A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat ) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
127-511: A Baja Bug is an original Volkswagen Beetle modified as an all-terrain vehicle to operate off-road (open desert, sand dunes and beaches), although other versions of air-cooled Volkswagens are sometimes modified as well. Baja bugs often race in off-road desert races such as the Baja 1000 . There are different classes for bugs, namely class 11, class 5 1600, and class 5 unlimited. According to desert racing association Score International , class 11
254-422: A "two-tube" shock absorber, this device consists of two nested cylindrical tubes, an inner tube that is called the "working tube" or the "pressure tube", and an outer tube called the "reserve tube". At the bottom of the device on the inside is a compression valve or base valve. When the piston is forced up or down by bumps in the road, hydraulic fluid moves between different chambers via small holes or "orifices" in
381-547: A 3.3% increase from the previous year. When including Audis produced at Ingolstadt, the combined output from Volkswagen and its Auto-Union company constituted 50.4% of all West German cars produced that year. In 1968, the Type 1 was officially given the name "Beetle" (from "der Käfer", German for beetle ). While it was largely successful in the 1960s, recording its highest sales growth in North America from 1960 to 1965,
508-459: A 90- mile-per-hour speedometer . On 30 July 1962, Volkswagen made several updates for the 1963 model year , including the incorporation of an air filter into the oil filter, the introduction of larger-diameter cylinder head induction ports and the adoption of plastic for the headliner and window guides. Volkswagen replaced the Wolfsburg crest on the hood, which had been present since 1951, with
635-456: A PSD shock absorber, which still consists of two nested tubes and still contains nitrogen gas, a set of grooves has been added to the pressure tube. These grooves allow the piston to move relatively freely in the middle range of travel (i.e., the most common street or highway use, called by engineers the "comfort zone") and to move with significantly less freedom in response to shifts to more irregular surfaces when upward and downward movement of
762-521: A car similarly shaped to the Beetle, more than five years before Porsche unveiled his initial "People's Car" design. Through a court ruling in 1953, Barényi successfully asserted his authorship and associated claims. He explained that he had previously elucidated the concept of the Beetle, which was already formulated in the 1920s, to Porsche in great detail. However, this concept was not protected sufficiently by patents . Key elements of this concept included
889-551: A complete disappearance of the "comfort vs. control" tradeoff, it also reduced pitch during vehicle braking and roll during turns. However, ASD shocks are usually only available as aftermarket changes to a vehicle and are only available from a limited number of manufacturers. Coilover shock absorbers are usually a kind of twin-tube gas charged shock absorber inside the helical road spring. They are common on motorcycles and scooter rear suspensions, and widely used on front and rear suspensions in cars. The principal design alternative to
1016-502: A compression valve, whose role has been taken up by the dividing piston, and although it contains nitrogen gas, the gas in a mono-tube shock is under high pressure (260-360 p.s.i. or so) which can actually help it to support some of the vehicle's weight, something which no other shock absorber is designed to do. Mercedes became the first auto manufacturer to install mono-tube shocks as standard equipment on some of their cars starting in 1958. They were manufactured by Bilstein , patented
1143-444: A correspondingly effective shock. The next phase in shock absorber evolution was the development of a shock absorber that could sense and respond to not just situational changes from "bumpy" to "smooth" but to individual bumps in the road in a near instantaneous reaction. This was achieved through a change in the design of the compression valve, and has been termed "acceleration sensitive damping" or "ASD". Not only does this result in
1270-399: A final target of 3,000 per day. During 1960, the company occasionally increased production by around 100; by the end of 1960, Volkswagen planned to produce 4,000 examples daily. Nordhoff stated, "Then we believe we shall have reached a balance between supply and demand so that we can finally deliver Volkswagens to customers without a waiting period". By the early 1960s, the Wolfsburg facility
1397-479: A full-flow oil filter , a 6.6:1 compression ratio —allowing for the use of unleaded fuel —and an electric fuel pump . A standard version was also released in 1993, featuring painted bumper bars and many minor removals. From 1997, front disc brakes and an immobiliser became available, and the De Luxe model featured small traffic indicator side lamps ahead of the top door hinge. The steering wheel's centre boss

#17327976518181524-477: A great future for racing due to its light weight and easy fitment. One of the earliest hydraulic dampers to go into production was the Telesco Shock Absorber, exhibited at the 1912 Olympia Motor Show and marketed by Polyrhoe Carburettors Ltd. This contained a spring inside the telescopic unit like the pure spring type 'shock absorbers' mentioned above, but also oil and an internal valve so that
1651-707: A lack of interest from British car manufacturers; an official report included the phrase, "The vehicle does not meet the fundamental technical requirement of a motor-car [...] it is quite unattractive to the average buyer [...] To build the car commercially would be a completely uneconomic enterprise." Instead, the factory remained operational by producing cars for the British Army . Allied dismantling policy changed from late 1946 to mid-1947. During this period, heavy industry in Germany continued until 1951. In March 1947, Herbert Hoover helped change policy by stating: There
1778-402: A large power hike. Basic modifications are simple. A lightweight, shortened fiberglass front body panel is fitted after the sheet metal from the trunk lid edge forward and rear engine deck lid and everything rearward (rear apron and engine compartment) is removed. The rear treatment leaves the engine totally exposed to aid in cooling. A tubular steel cage, along with a front and rear bumper,
1905-677: A lawsuit, halted only by Germany's invasion of Czechoslovakia in 1938, leading to the Nazi administration of the Tatra factory in October. Hitler instructed Tatra to focus exclusively on heavy trucks and diesel engines, discontinuing all car models except the V8-engined Tatra 87 . The issue resurfaced post-World War II, and in 1965, Volkswagen paid Ringhoffer-Tatra 1,000,000 Deutsche Marks in an out-of-court settlement. The name Volkswagen
2032-594: A longer engine cowl and longer rear fenders that original VW Bug rear lights could be mounted to. It was this 1971 kit that inspired the Tamiya Sand Scorcher radio controlled Baja Bug. The 1971 update was also due to updated regulations in California regarding engine coverage. In many US states and other countries, the headlight spacing of the Bugeye kits was illegal - the headlights were close together in
2159-425: A political organisation aimed at providing the populace with leisure activities) was in charge of this project. Robert Ley , the Nazi official heading Kraft durch Freude (KdF), announced in 1938 that every German would own a Volkswagen within ten years. However, there were challenges. Gasoline prices in Germany were high due to taxes, making it expensive for private car ownership. Gasoline was also primarily used for
2286-569: A quick and inexpensive part exchange. As Hitler explained, the reason for choosing an air-cooled engine was that many rural doctors did not have access to garages for maintaining coolant. On 22 June 1934, Ferdinand Porsche received a development contract from the Verband der Automobilindustrie (German Association of the Automotive Industry) for the prototype of an inexpensive and economical passenger car after Hitler decided there
2413-518: A savings plan to buy a car. At that time, Germany had fewer cars than other European countries. In 1930, there were only about 500,000 registered cars in Germany, while France and Great Britain had over 1 million each, and the USA had more than 26 million. However, the onset of the Second World War hindered the distribution of the cars, and there was a lack of time for series production . With
2540-415: A significant downturn, leading to the loss of many dealerships for the company. In 1991, the planning of a new car began once J Mays and Freeman Thomas returned to California to open Volkswagen's Design Centre at Simi Valley . Recognising that Japanese manufacturers dominated the market in the 1970s and '80s, Volkswagen needed to introduce a vehicle to regain popularity. Before this, the company began
2667-408: A slight curvature, replacing its flat configuration. Door windows also expanded by 6%, with a slight backward canting of door vent window edges. Rear side windows increased by 17.5%, and the rear window by 19.5%. In 1967, updates comprised shortened front and rear bonnets, box-profile bumpers with a railway rails design that were installed at a higher position, vertically oriented scattering discs for

By March of the same year, the export model began to be equipped with a hydraulic brake system , which became a standard feature from April onwards. In 1952, the equipment was enhanced with the addition of vent windows in the doors, and the wheels were reduced to a diameter of 15 inches (380 mm) from the previous 16 inches (410 mm). On 10 March 1953,

They are equipped with the AP engine from the early Volkswagen Golf generations, and can be feeded by carburetor or electronic injection . Baja Bugs originated in Southern California in the late 1960s as an inexpensive answer to the successful Volkswagen-based dune buggies of the mid-1960s, especially the Meyers Manx . The building of
3048-467: Is a stock VW beetle with modifications limited to ground clearance and strength. Class 5 1600 rules state that a 1600 cc VW engine must be used and the car must have the exterior appearance of a "baja bug" with body modification limited to whatever cutting is needed to install a consumer baja kit. Class 5 unlimited is any 4 cylinder VW-style engine , and it must have Baja-style fenders and side panels, and VW-style suspension .. Another version of Baja Bug
3175-404: Is a dramatic reduction in "foaming" or "aeration", the undesirable outcome of a twin-tube overheating and failing which presents as foaming hydraulic fluid dripping out of the assembly. Twin-tube gas charged shock absorbers represent the vast majority of original modern vehicle suspension installations. Often abbreviated simply as "PSD", this design is another evolution of the twin-tube shock. In
3302-419: Is a hydraulic shock absorber, which usually includes a piston, a cylinder, and an oil-filled chamber. The piston is connected to the piston rod, which extends into the cylinder and divides the cylinder into two parts. One chamber is filled with hydraulic oil, while the other chamber contains compressed oil or air. When there is an accident or vibration in the vehicle, the piston moves into the cylinder, forcing
3429-514: Is compatible with electronic control. Primary among benefits cited in Multimatic ’s 2010 patent filing is the elimination of performance ambiguity associated with flexible shims, resulting in mathematically predictable, repeatable, and robust pressure-flow characteristics. An extra tube or container of oil connected to the oil compartment of the (main) shock via a flexible pipe (remote reservoir) or inflexible pipe (piggy-back shock). Increases
3556-400: Is constantly evolving due to the continuous improvement of vehicle dynamics and passenger comfort. In common with carriages and railway locomotives, most early motor vehicles used leaf springs . One of the features of these springs was that the friction between the leaves offered a degree of damping, and in a 1912 review of vehicle suspension, the lack of this characteristic in helical springs
3683-553: Is fitted to the body and floor pan for protection of engine and occupants. Shortened fiberglass fenders both front and rear meant removal of the Beetle's distinctive running boards and the likely addition of more tubular steel parts (side bars) in their place. The rugged torsion bar front and rear suspension standard on the Beetle, allows it to withstand the rigors of offroading and the rear ride height to easily be raised slightly and stiffened to make clearance for larger heavy-duty off-road tires and wheels. The relatively light front end of

The front indicators were relocated to the front bonnet within chrome housings, and the rear indicators were integrated into the tail lamps . In January, the valve-clearing adjusting nut was slightly enlarged and resistor-type ignition leads were adopted. In March, Volkswagen made several modifications to its front trailing arm and
3937-534: Is the illusion that the New Germany left after the annexations can be reduced to a " pastoral state ". It cannot be done unless we exterminate or move 25,000,000 people out of it. Major Ivan Hirst (1916–2000), a British Army officer, has been widely acknowledged for the reopening of the factory. Hirst was ordered to take control of the heavily bombed factory, which the Americans had captured. Recognising

4064-913: Is to damp spring oscillations. Shock absorbers use valving of oil and gasses to absorb excess energy from the springs. Spring rates are chosen by the manufacturer based on the weight of the vehicle, loaded and unloaded. Some people use shocks to modify spring rates but this is not the correct use. Along with hysteresis in the tire itself, they damp the energy stored in the motion of the unsprung weight up and down. Effective wheel bounce damping may require tuning shocks to an optimal resistance. Spring -based shock absorbers commonly use coil springs or leaf springs , though torsion bars are used in torsional shocks as well. Ideal springs alone, however, are not shock absorbers, as springs only store and do not dissipate or absorb energy. Vehicles typically employ both hydraulic shock absorbers and springs or torsion bars. In this combination, "shock absorber" refers specifically to
4191-482: The Golf in 1974. In the late 1970s and '80s, Japanese automakers began to dominate the market, which contributed to the Beetle's declining popularity. Over its lifespan, the Beetle's design remained consistent, yet Volkswagen implemented over 78,000 incremental updates. These modifications were often subtle, involving minor alterations to its exterior, interior, colours, and lighting. Some more noteworthy changes included
4318-522: The Kommandeurswagen persisted until 1944 when the production at the plant halted due to the extensive damage inflicted by the Allied air raids. Due to gasoline shortages late in the war, a few " Holzbrenner " (wood-burner) Beetles were built fueled with wood logs. Planned for September 1939, Kraft durch Freude arranged an event to showcase Germany's Autobahn highway system and to promote
4445-552: The Puebla plant in Mexico, Volkswagen produced the final Type 1, after 21,529,464 examples were produced globally during its tenure. Its production span of 65 years is the longest of any single generation of automobile, and its total production of over 21.5 million is the most of any car of a single platform . To celebrate the occasion, Volkswagen marketed a series of 3,000 Beetles as "Última Edición" (Final Edition). While

Hitler, an avid automotive enthusiast, rode in Tatras multiple times during political tours of Czechoslovakia and had frequent dinners with Ledwinka. Following one such tour, Hitler remarked to Porsche, "This is the car for my roads". From 1933 onwards, Ledwinka and Porsche met regularly to discuss their designs, and Porsche admitted, "Well, sometimes I looked over his shoulder, and sometimes he looked over mine" while designing
4699-524: The Volkswagen Type 1 , is a small family car produced by the German company Volkswagen from 1938 to 2003. One of the most iconic cars in automotive history, the Beetle is noted for its distinctive shape. Its production period of 65 years is the longest of any single generation of automobile, and its total production of over 21.5 million is the most of any car of a single platform . The Beetle

The Beetle suspension "stops" can be moved to allow more suspension travel. Longer shock absorbers , for the increase in suspension travel, provide more damping control over bumps giving more driver control and comfort. Some people eliminate
5461-624: The Beetle in the 1960s, including 1200, 1300, 1500, 1600, 1302, and 1303. Volkswagen introduced a series of large luxury models throughout the 1960s and 1970s—comprising the Type 3 , Type 4 and the K70 —to supplement the Beetle, but none of these models achieved the level of success that it did. Rapidly changing consumer preferences toward front-wheel drive compact hatchbacks in Europe prompted Volkswagen's gradual shift away from rear-wheel drive, starting with
5588-596: The Beetle started facing competition from more contemporary designs worldwide in the 1970s. The decade started out well for Volkswagen, which sold 569,000 Beetles in 1970. In 1970, fifteen Volkswagen dealerships in Washington convened to implement the Volkswagen American Dealers Association , which was made to preserve a free market of imported international automobiles through political pressure and lobbying. On 17 February 1972,
5715-614: The Beetle. As opposed to the Beetle, the Golf was substantially redesigned over its lifetime, with only a few components carried over between generations. On 10 January 1980, the final Beetle convertible of 330,281 rolled off the production line at the Karmann facility in Osnabrück . It was the most successful convertible for a long time and was replaced by the first Golf cabriolet in 1979. The number of Beetle units sold by Volkswagen
5842-489: The Forces of Occupation received 20,991 cars, leaving less than 10,000 for export or domestic consumption. The number of employees increased from 6,033 by the end of 1945 to almost 57,000 in 1957. After the war, over 10,000 apartments were built to house the workers in Wolfsburg, which then had a population of nearly 60,000. In 1959, Volkswagen invested more than DM500 million to increase daily production by 1,000, reaching
5969-551: The Gabriel Snubber started being fitted in the late 1900s (also the similar Stromberg Anti-Shox). These used a belt coiled inside a device such that it freely wound in under the action of a coiled spring but met friction when drawn out. Gabriel Snubbers were fitted to an 11.9HP Arrol-Johnston car which broke the 6 hour Class B record at Brooklands in late 1912, and the Automator journal noted that this snubber might have
6096-604: The Mexican 1000 of 1968 in Baja California . The first fiberglass Baja kit (bug eye kit) was not introduced until 1969 by the Miller-Havens company. The original "Bugeye" kit by Miller-Havens Enterprises was widely copied - Drino Miller estimated that at least 8 of the original 10 kits sold were “Splashed” (used to make copy moulds). Miller-Havens modified the rear panels of the original Bugeye kit in mid 1971 to add
6223-534: The Second World War because the Volkswagen plant at Fallersleben (now Wolfsburg ), founded in May 1938, was not yet finished. During the war, other German manufacturers were concurrently producing military vehicles and armaments , so the series production of the then-called Volkswagen car could not begin until peacetime; nevertheless, 210 KdF-Wagens were manufactured by the end of the war in May 1945. Following
6350-480: The Type 1 and used by the Wehrmacht . These vehicles, including several hundred Kommandeurswagen (Type 87), featured a Type 1 Beetle body mounted on the robust chassis of the four-wheel-drive Type 86 Kübelwagen prototype. The Kommandeurswagen included a portal axle, a Schwimmwagen drivetrain, wider fenders, and oversized Kronprinz all-terrain tyres, reminiscent of the later Baja Bugs . The production of
6477-508: The Type 60 K 10, officially known as the Porsche 64 . Although the engineers produced three vehicles, they never made it to the race due to the outbreak of war before the scheduled date; two of them disappeared during the conflict. Austrian Otto Mathé acquired the third Berlin-Rome car and raced it throughout the 1950s, becoming the fastest in its class during the 1950 Alpine Cup. He continued to use it until his death in 1995.

#17327976518186604-406: The Type 60 before 1946, received the dub "Pretzel Beetle" due to its distinctive oval-shaped, vertically divided rear window. On 1 July 1949, the Volkswagen lineup was expanded to include the "export" model featuring enhanced interiors, chrome bumpers, and trim. It was offered in a variety of colours to distinguish it from the preceding "Standard" model. Starting in 1950, an optional sunroof with
6731-460: The Type 60 by Porsche, the Beetle project involved a team of designers and engineers comprising Erwin Komenda , who specialised in the bodywork; Josef Kales, responsible for the engine design; Karl Rabe , serving as the chief engineer; and Josef Mickl and Franz Xaver Reimspiess, the latter credited for devising the iconic Volkswagen badge. The project saw significant milestones in October 1935 with
6858-750: The V3s underwent over 50,000 km (31,000 mi) of testing across various terrains. A series of thirty W30 development models, commissioned by Porsche and manufactured by Daimler-Benz, underwent testing in early April 1937, covering a total distance of over 2,900,000 kilometres (1,800,000 mi). All vehicles featured the characteristic rounded design and included air-cooled , rear-mounted engines . A further batch of 44 VW38 pre-production cars produced in 1938 introduced split rear windows, and subsequently, Volkswagen introduced fifty VW39 cars, completed in July 1939.

In the 1960s and '70s, Volkswagen augmented its product portfolio with several models to supplement the Type 1—the Type 3 , the Type 4 and the NSU -based K70 sedan. None of these models achieved the level of success of the Beetle. The overdependence on a singular model, which was experiencing a decline in popularity, meant that Volkswagen

Following the war, numerous KdF savers pressed for the receipt of a Volkswagen. When their request was denied, the VW saver initiative ensued, spanning several years. During the war, the factory predominantly built the Kübelwagen (Type 82), the Schwimmwagen (Type 166) and numerous other light utility vehicles . These vehicles were derived mechanically from

It accommodated five passengers in its compact four-door body, which provided luggage storage under the front bonnet and behind the rear seats. Just before the outbreak of World War II , Tatra filed numerous legal claims against VW for patent infringement. Tatra launched
7493-437: The action of the auxiliary spring in the unit itself. The first production hydraulic dampers to act on the main leaf spring movement were probably those based on an original concept by Maurice Houdaille patented in 1908 and 1909. These used a lever arm which moved hydraulically damped vanes inside the unit. The main advantage over the friction disk dampers was that it would resist sudden movement but allow slow movement, whereas
7620-464: The adoption of the crankshaft from the Type 3 . This extended the stroke from 64 mm (2.5 in) to 69 mm (2.7 in), resulting in an engine displacement of approximately 78 cubic inches (1,280 cm ). 1965 also marked the Beetle's most extensive design change when its body stampings were extensively revised. It allowed for significantly larger windows, a departure from previous designs. The windshield increased by 11% in area and adopted

The testing of three additional V3 prototypes began on 11 July 1936, the first of which was driven to Obersalzberg and inspected by Hitler. Two V3s were delivered to Berlin in August for examination by other Nazi Party officials, who showed great interest in them. By June 1936,
8509-657: The concept in its final form, which was slated for completion by the end of the century. To help gauge public demand of the forthcoming automobile in the United States, Volkswagen implemented a free-access telephone line to allow members to express their thoughts on the car. The line quickly became inundated with calls, with many saying, "You build it, I'll buy it!" Work on the Concept One continued, with further redesigns on its front fascia . To reduce production investments and expenses, Volkswagen initially planned to use

Ganz personally drove a Hanomag Kommissbrot and a swing-axle Tatra—both featuring elements such as a central tubular frame, independent wheel suspension, and a rear/mid-engine design. Ganz incorporated these technical features into his proposed vehicle designs. Hitler reportedly saw cars designed by Josef Ganz at

Spool valve dampers are characterized by the use of hollow cylindrical sleeves with machined-in oil passages as opposed to traditional conventional flexible discs or shims. Spool valving can be applied with monotube, twin-tube, or position-sensitive packaging, and
8890-416: The design of the Beetle changed little over its lifespan, Volkswagen implemented over 78,000 incremental updates. Typically subtle, these alterations usually involved minor updates to the exterior, interior, colours and lighting. More noteworthy changes have comprised new engines, models and systems, such as updated dashboards and hydraulic braking . The Type 11 standard limousine, initially designated as
9017-460: The development of a city car, codenamed " Chico ", in which they invested millions of Deutsche Marks . In 1993, the brand stated that the Chico was intended to begin production in 1995. However, this plan was abandoned once Volkswagen realised that the project was commercially infeasible. Mays and Thomas recognised the difficulties faced by the brand and suggested the need for a vehicle that included
9144-419: The dissipated energy can be stored and used later. In general terms, shock absorbers help cushion vehicles on uneven roads and keep wheels in contact with the ground. In a vehicle, shock absorbers reduce the effect of traveling over rough ground, leading to improved ride quality and vehicle handling . While shock absorbers serve the purpose of limiting excessive suspension movement, their intended main purpose
9271-430: The effort to infuse the Beetle with a modernised design, this did not resonate with consumers, resulting in declining Beetle sales. In 1975, the 1303 and 1303S received rack and pinion steering, but in July of that year, Volkswagen discontinued both of them. The long-serving 1200 was renamed the "1200L" in 1976, with the additional deluxe features incorporated into the car's interior. In July 1984, Volkswagen eliminated
9398-632: The engine lid louvres. Starting in 1986, for the 1987 model year , the sole model available was the single-carburettor version with 98 cubic inches (1,600 cm ). From late 1992 for the 1993 model year, Volkswagen standardised catalytic converters , the Bosch Digifant engine management system , a lambda probe and electric ignition . This fuel-injection system proved much more straightforward and reliable than previous injection systems used on German-assembled Volkswagens since 1967. Vehicles with these modifications can be identified externally by
9525-399: The engines to breathe more effortlessly. The British automotive magazine Autocar expressed disappointment in its power increase, noting, "Even with 14 [per cent] more power, the total output of 50 bhp is very modest for the size of the engine". The Super Beetle had a 2 cm (0.8 in) increase in wheelbase , but the extra space was in front of the windshield. For 1971,
9652-511: The final Beetle was produced at the Wolfsburg plant after 11,916,519 examples were made there. Following its discontinuation, Volkswagen ceased the ongoing development of the Beetle in Germany. On 19 January 1978, the last Beetle sedan manufactured in Europe rolled off the production line at the Emden plant with the chassis number 1182034030. After its discontinuation in Germany, production of
9779-625: The first Baja Bug is generally credited to Gary Emory (now of Parts Obsolete), circa 1968. Gary and his hot rodder father, Neil Emory, built the car in the bodyshop at the Chick Iverson Volkswagen dealership in Newport Beach, California; Gary worked in the parts department there after leaving school and Neil was working in the bodyshop. The first Baja Bug in racing is credited to Dave Deal, the Californian cartoonist, in
9906-442: The flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders , the hydraulic fluid heats up, while in air cylinders , the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types,
10033-407: The former has a capacity of 96.7 cubic inches (1,584 cm ). In English-speaking countries, the name "Super Beetle"—alongside "1600"—was included on the written description but not the engine cover. The 1302 possessed the same 32.4 kW (44 PS) output as the 1300, whereas the 1302S saw an increase to 36.8 kW (50 PS). This was facilitated by a twin-port cylinder head , enabling
10160-428: The front bonnet and behind the rear seat, and it has a drag coefficient of 0.48. The bodywork attached with eighteen bolts to the Beetle's nearly flat platform chassis featured a central structural tunnel. The front and rear suspension incorporated torsion bars and a front stabiliser bar, providing independent suspension at all wheels, albeit the front axle was designed with double longitudinal trailing arms, whereas
10287-661: The front panel, similar to early Land Rovers. In mid-1972, Don Rountree of the Sandwinder Company/R&;H Fiberglass launched the first wide-eye Baja bug kit (Designed by Barry "Burly" Burlile) - the headlights of the Sandwinder kit were mounted in the front fenders and the rear panels were much longer. The Sandwinder one-piece flip front was then used on the majority of Baja racers cars. In the early days before fiberglass body panels became available, enthusiast and racers simply made their own modification to both
10414-415: The headlights and larger rear lights with an iron design. Volkswagen introduced external fuel filler flap, eliminating the need to open the front bonnet for refuelling. In September 1967, the 1500 Beetle was introduced. Its engine displacement was approximately 91.1 cubic inches (1,493 cm ), its power output was 32 kW (43 hp) and it featured a three-speed semi-automatic transmission . In 1968,
10541-524: The hydraulic fluid through small holes, creating resistance and dissipating energy in the form of heat. This dampens oscillations, reducing further bouncing or wobble of the car. Shock construction requires a balance of features such as piston design, fluid viscosity, and overall size of the unit to ensure performance. As technology developed, other types of shock absorbers emerged, including gas and electric shock absorbers, that provided improved control and flexibility. The design and manufacture of shock absorbers
10668-430: The hydraulic piston that absorbs and dissipates vibration. Now, composite suspension systems are used mainly in 2 wheelers and also leaf springs are made up of composite material in 4 wheelers. Shock absorbers are an important part of car suspension designed to increase comfort, stability and overall safety. The shock absorber, produced with precision and engineering skills, has many important features. The most common type
10795-422: The introduction of new engines, models and systems, such as improved technology or comfort. In May 1934, at a meeting at Berlin's Kaiserhof Hotel , the leader of Nazi Germany , Adolf Hitler , insisted on the development of a vehicle that could accommodate two adults and three children while not using more than seven litres of fuel per 100 km (33.6 mpg US/40.4 mpg UK). All components were designed for
10922-500: The key components. Once Heinrich Nordhoff assumed management at Volkswagenwerk , manufacturing capacity increased significantly. Production in 1946 and 1947 was rated at 9,878 and 8,973 examples, respectively, but in Nordhoff's first year, 1948, manufacture doubled to approximately 19,244 units. On 6 August 1955, the millionth example was assembled and by 1959, production capacity was rated at 700,000 units per year. By mid-1948,
11049-465: The locations in which it was manufactured. Official exportation of the Beetle to the Brazilian market began on 23 March 1953, with its parts imported from Germany. For the local market, the Type 1 was officially known "Volkswagen Fusca". In January 1959, Volkswagen shifted assembly to the new São Bernardo do Campo plant, initially maintaining 60 per cent of its German parts. However, by
11176-529: The mid-1960s, the cars had about 99.93 per cent Brazilian-made components. Production persisted until 1986, after over 3.3 million examples were produced there, and resumed in 1992, extending until 1996. The production of the Beetle was possible through agreements with companies like Chrysler in Mexico and the Studebaker-Packard Corporation , which assembled cars imported in complete knock-down form. The Beetle
11303-399: The military in the Nazi regime. Despite that, the Nazi leaders saw the mass-produced car as a way to promote their system. It symbolised a shift from cars being a privilege for the wealthy to a dream that lower-class Germans could now fulfil. Hitler was particularly enthusiastic about it because the car could easily be adapted for military use. The KdF-Wagen was not series-produced before
11430-407: The new model, some of which were minor. Noteworthy changes comprised an automatic choke, an anti-icing carburettor heater , a redesigned fuel tank that increased boot capacity , an external gas tank vent to prevent odours in the car, standard windshield wipers and a new ignition switch. Stylistic improvements included new paint colours and interior design options, a coloured steering wheel and
11557-419: The oil damped in the rebound direction. The Telesco unit was fitted at the rear end of the leaf spring, in place of the rear spring to chassis mount, so that it formed part of the springing system, albeit a hydraulically damped part. This layout was presumably selected as it was easy to apply to existing vehicles, but it meant the hydraulic damping was not applied to the action of the main leaf spring, but only to
11684-468: The overall length increased by 8 cm (3.1 in), doubling the front trunk capacity and adding 3 cu ft (0.1 m ) of luggage space. Volkswagen also implemented a new fresh-air ventilation system, drawing its air from the rear quarter panels. In August 1972, the 1303 range superseded the 1302 model, which featured a curved windshield. This design change elicited mixed opinions; some favoured it, while others expressed dissatisfaction. Despite
11811-414: The piston and via the valve, converting the "shock" energy into heat which must then be dissipated. Variously known as a "gas cell two-tube" or similarly named design, this variation represented a significant advancement over the basic twin-tube form. Its overall structure is very similar to the twin-tube, but a low-pressure charge of nitrogen gas is added to the reserve tube. The result of this alteration
11938-465: The piston starts to occur with greater intensity (i.e., on bumpy sections of roads— the stiffening gives the driver greater control of movement over the vehicle so its range on either side of the comfort zone is called the "control zone"). This advance allowed car designers to make a shock absorber tailored to specific makes and models of vehicles and to take into account a given vehicle's size and weight, its maneuverability, its horsepower, etc. in creating
12065-582: The platform of the Polo . However, in 1995, at the Tokyo Motor Show , the company unveiled another prototype , sharing its wheelbase and its broader range of engine options with the Golf . Simultaneously, Volkswagen announced that it would be named the "New Beetle". After over six years of planning and development, Volkswagen introduced the New Beetle in 1997. On 30 July 2003 at 9:05 a.m., at
12192-455: The pressure tube in response to changes in road smoothness. The two pistons also completely separate the shock's fluid and gas components. The mono-tube shock absorber is consistently a much longer overall design than the twin-tubes, making it difficult to mount in passenger cars designed for twin-tube shocks. However, unlike the twin-tubes, the mono-tube shock can be mounted either way— it does not have any directionality. It also does not have
12319-435: The previous model; it was a horizontally opposed , overhead valve , four-cylinder air-cooled engine . It generated 40 kilowatts (54 PS; 54 hp) at 3,900 rpm and produced 83 newton-metres (61 lbf⋅ft) at 2,000 rpm. The 1961 Beetle introduced a full-synchronised four-speed manual transmission , replacing the former non-synchronised first gear. The Volkswagen facility implemented 27 alterations to
12446-508: The purported beginning of the production of the KdF-Wagen , involving a 1,500-kilometre (930 mi) journey from Berlin to Rome. Erwin Komenda supervised the development process, while Karl Froelich was responsible for creating official plans that they subsequently used to form a wooden scale model. The model was wind tunnel tested at Stuttgart University by Josef Mickl. Dubbed the "Berlin-Rome car", Porsche AG's engineers designed
12573-502: The ratio is now down to about every four [Volkswagens] out of every ten. If the current VW starts to slip, the new [Type 3]—soon to be introduced—probably will be imported to justify the [company's] more than 600 [Volkswagen] dealerships and the $ 100 million investment in facilities". He continued by expressing that the Type 3 had failed to leave a positive impression on industry executives in both Europe and North America. The new engine essentially possessed identical specifications as
12700-541: The rear axle was a swing axle . Light alloy forms the Beetle's engine, transmission, and cylinder heads. German-Bohemian Ferdinand Porsche (1875–1951) and his team were generally known as the original designers of the Volkswagen. However, there has been debate over whether he was the original designer. Rumours circulated, suggesting that other designers, such as Béla Barényi , Paul Jaray , Josef Ganz and Hans Ledwinka , may have influenced its design. In 1925, Austro-Hungarian automotive engineer Béla Barényi designed
12827-410: The recognisable design of the Beetle as a potential solution to improve customer appeal. During development, this car was known as the "Concept One" project. The prototype version of the project was revealed at the 1994 Detroit Motor Show , and a red convertible variant of the model was showcased at the 1995 Geneva Motor Show . It took a year for Volkswagen to officially confirm the production of
12954-401: The reintroduced louvred engine lid, heavier and larger bumper bars, four-stud wheels with twenty ventilation holes and a "1600i" badge on the engine lid. The 1993 model also featured a third-generation Golf -style steering wheel and front seats, a protection alarm, handbrake and engine compartment lamps and an optional ZF limited-slip differential . The engine received hydraulic tappets ,
13081-529: The rotary friction dampers tended to stick and then offer the same resistance regardless of speed of movement. There appears to have been little progress on commercialising the lever arm shock absorbers until after World War I , after which they came into widespread use, for example as standard equipment on the 1927 Ford Model A and manufactured by Houde Engineering Corporation of Buffalo, NY. Most vehicular shock absorbers are either twin-tube or mono-tube types with some variations on these themes. Also known as
13208-602: The scarcity of occupations in Germany and the shortage of vehicles in the British Army, Hirst persuaded the British military to order 20,000 cars, stating that it "was the limit set by the availability of materials". By March 1946, production capacity was rated at approximately 1,000 units per month. Based on an eight-hour shift in mid-1946, production was around 2,500 per month. At the time, about 1,800 machine tools were in operation, of which 200 were used exclusively for
13335-467: The split rear window was replaced with a one-piece rear window. Starting in 1954, the Type 122 engine had a 77 mm (3.0 in) cylinder bore , increased by 2 mm (0.08 in), and an engine displacement of 1,192 cc (1.19 L; 72.74 cu in), surpassing the previous 1,131 cc (1.1 L; 69.0 cu in). This engine produced 22 kW (30 PS), a 4 kW (5.4 PS) improvement over its predecessor. In 1955,
13462-526: The spring and vehicle combination bounced with a characteristic frequency, these auxiliary springs were designed with a different period, but were not a solution to the problem that the spring rebound after striking a bump could throw you out of your seat. What was called for was damping that operated on the rebound. Although C.L. Horock came up with a design in 1901 that had hydraulic damping, it worked in one direction only. It does not seem to have gone into production right away, whereas mechanical dampers such as
13589-458: The steering damper. In May 1960, Volkswagen added plastic warm air ducts to decrease noise. In the mid-1960s, the traditional labels "standard" and "export" for the Beetle's model variants were superseded by numerical designations, approximately correlating with the engine displacements. In the October 1961 issue of Motor Trend , Don Werner noted, "Five years ago, out of every ten imported cars sold, six were Volkswagens. [The] latest figures show
13716-802: The time given us. The wheel of history never turns back! Whatever opportunities you miss today will never return! The new year will have 366 days this time; every day, we will cross one off—and soon there will be only four left. No power of heaven or earth will bring those days back. Let us use this time, as long as we are free to do so, as we are now, and as we shall still be for a few years. The Emden facility represented an expenditure exceeding DM154.4 million, with Beetle operations beginning there on 1 December 1964. By late 1965, Volkswagen's annual production exceeded 1,600,000 units, averaging 6,800 units per day. Volkswagen's share of all cars produced in West Germany reached 48.6 per cent, representing
13843-518: The torsion bar suspension and install coilover-type springs that mount to a roll cage, allowing extreme amounts of travel with a very comfortable ride. There are two basic styles, The Narrow and Wide Eye Baja Bug. The Narrow Eye (Bugeye) places the headlights on the front apron (see picture below); while, the Wide Eye has the headlights on the front fenders in more or less the stock location. Volkswagen Beetle The Volkswagen Beetle , officially
13970-548: The total West German automotive market and 42.3 per cent of sub-2,750 lb (1,250 kg) commercial vehicle market there. Nordhoff's recurring encouragement proved to be highly effective. He consistently urged the team to work harder, reduce expenses and avoid complacency and corporate inefficiencies. In January 1960, Nordhoff quoted: We shall some day speak of the Golden Fifties . We are now moving away from them and we must recognise that fact and use
14097-416: The traditional VW semaphore turn signals were replaced by conventional flashing directional indicator lamps for North America, followed by their worldwide replacement in 1961. In 1958, the Beetle received a revised instrument panel, and a larger rectangular rear window replaced the previous oval design. "The 1961 Volkswagen sedan provides the kind of happy surprise that comes when an excellent motor vehicle
14224-452: The twin-tube form has been the mono-tube shock absorber which was considered a revolutionary advancement when it appeared in the 1950s. As its name implies, the mono-tube shock, which is also a gas-pressurized shock and also comes in a coilover format, consists of only one tube, the pressure tube, though it has two pistons. These pistons are called the working piston and the dividing or floating piston, and they move in relative synchrony inside
14351-431: The war, the Beetle experienced a significant growth in success. On 11 April 1945, Fallersleben , where 17,000 people lived, was officially designated " Wolfsburg ". Official series manufacture of the saloon began on 27 December 1945; Volkswagen made fifty-five vehicles by the end of the year. The Volkswagen facility, initially slated for dismantling and transportation to Britain under American control in 1945, faced
14478-573: The world car production record was broken by the Beetle, with a total of 15,007,034 units produced worldwide, thereby surpassing the production figure that had been held by the American Ford Model T for nearly fifty years. Volkswagen donated the car to the Smithsonian Institution for permanent exhibition in its industrial history section. By 1973, over 16 million Beetles had been manufactured. On 1 July 1974,
14605-467: Was a need for a people's car —a car affordable and practical enough for lower-class people to own—to serve the country's new road network, the Reichsautobahn . Although the Volkswagen Beetle was primarily the conception of Porsche and Hitler, the idea of a "people's car" is much older than Nazism and has existed since the introduction of automotive mass-production. Originally designated as
14732-443: Was also fitted to many cars. One of the problems with motor cars was the large variation in sprung weight between lightly loaded and fully loaded, especially for the rear springs. When heavily loaded the springs could bottom out, and apart from fitting rubber 'bump stops', there were attempts to use heavy main springs with auxiliary springs to smooth the ride when lightly loaded, which were often called 'shock absorbers'. Realizing that
14859-460: Was at its lowest in the 1980s. The Beetle faced competition from Japanese automakers such as Toyota and Honda , whose cars were uprated in reliability and performance. The closure of Volkswagen's Pennsylvania factory was due to high costs, subpar quality, and poor sales. In the United States, Volkswagen introduced the Rabbit and Corrado , both of which had little success. The overall sales suffered
14986-427: Was available with a semi-automatic transmission and radial-ply tyres . In 1970, the 1500 received a new carburettor and dual circuit braking, and Volkswagen discontinued the 1500. In 1971, the 1200 received a larger windscreen, while the 1300 received a power increase to 32 kW (43 hp) and larger brakes, effectively replacing the 1500. Volkswagen replaced the 1300 with the 1300A "economy version" in 1973 for
15113-485: Was conceived in the early 1930s. The leader of Nazi Germany, Adolf Hitler , decided there was a need for a people's car —an inexpensive, simple, mass-produced car—to serve Germany's new road network, the Reichsautobahn . The German engineer Ferdinand Porsche and his design team began developing and designing the car in the early 1930s, but the fundamental design concept can be attributed to Béla Barényi in 1925, predating Porsche's claims by almost ten years. The result
15240-659: Was in a financial crisis and needed German government funding to produce the Beetle's replacement. Consequently, the company introduced a new generation of water-cooled, front-engined, front-wheel-drive models, including the Golf , the Passat , the Polo and the Scirocco , all of which were styled by the Italian automotive designer Giorgetto Giugiaro . By 1979, the Golf constituted over 50 per cent of Volkswagen sales, and it eventually became Volkswagen's most successful model since
15367-638: Was introduced to the Mexican market in 1954, and began official production ten years later. The local market referred to the Beetle as the "Vocho". The introduction of a new taxi regulation in Mexico City, requiring only four-door vehicles to be permitted to prevent robberies, influenced Volkswagen's decision to the end of the production of the Beetle in 2003. Shock absorber Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control
15494-430: Was massive. It accommodated about 10,000 production machines and covered 10.8 million square feet in roofed area, more than the combined residential area in Wolfsburg . Daily production increased to approximately 5,091, and the plant employed over 43,500 workers. By 1962, Nordhoff had spent over DM675 million in expanding the factory. At that time, Volkswagen sales constituted 34.5 per cent of
15621-500: Was no longer positioned diagonally at the front under the hood but instead rested horizontally under a cover in the trunk area. The company initially intended to designate the car as the "1301", but a trademark already held by the French company Simca compelled Volkswagen to use "1302" instead. Volkswagen produced the more powerful 1302S alongside the 1302. The latter has an engine displacement of 79 cubic inches (1,300 cm ), while
15748-468: Was officially substituted by the term KdF ( Kraft durch Freude ; German for 'Strength Through Joy') derived from the Nazi organisation once Hitler ceremoniously laid the foundation stone for the Volkswagen factory on 26 May 1938. As part of this organisation, Volkswagen urged workers to "save five marks a week and get your car". Before the completion of the KdF factory, many Germans had already signed up for
15875-522: Was restyled to resemble that of the contemporary Golf and Polo. In 1998, Volkswagen removed the small through-flow ventilation slots behind the rear side windows and standardised front disc brakes. Furthermore, Volkswagen included a security alarm as standard and removed the "1600i" inscription from the engine lid. Over its 65-year tenure, Volkswagen produced the Volkswagen Type 1 in numerous locations worldwide. The following list encompasses all
16002-422: Was the Volkswagen Type 1 and the introduction of the Volkswagen brand. Volkswagen initially slated production for the late 1930s, but the outbreak of war in 1939 meant that production was delayed until the war had ended. The car was originally called the Volkswagen Type 1 and marketed simply as the Volkswagen. It was not until 1968 that it was officially named the "Beetle". Volkswagen implemented designations for
16129-533: Was the reason it was "impossible" to use them as main springs. However the amount of damping provided by leaf spring friction was limited and variable according to the conditions of the springs, and whether wet or dry. It also operated in both directions. Motorcycle front suspension adopted coil sprung Druid forks from about 1906, and similar designs later added Friction disk shock absorber rotary friction dampers, which damped both ways - but they were adjustable (e.g. 1924 Webb forks). These friction disk shock absorber s
