The Saviem SM was a range of medium trucks produced by the French manufacturer Saviem between 1967 and 1975.
62-515: The Société Anonyme de Véhicules Industriels et d'Équipements Mécaniques ( French pronunciation: [sɔsjete anɔnim də veikyl ɛ̃dystʁijɛl e dekipmɑ̃ mekanik] ), commonly known by the acronym Saviem ( French pronunciation: [savjɛm] ), was a French manufacturer of trucks and buses/coaches part of the Renault group, headquartered in Suresnes , Île-de-France . The company
124-406: A fifth wheel hitch. Box trucks have walls and a roof, making an enclosed load space. The rear has doors for unloading; a side door is sometimes fitted. Chassis cab trucks have a fully enclosed cab at the front, with bare chassis frame-rails behind, suitable for subsequent permanent attachment of a specialized payload, like a fire-truck or ambulance body. Concrete mixers have
186-493: A motor vehicle designed to transport freight , carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles . Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in
248-485: A 25 mph (40 km/h) speed governor as they are classified as low-speed vehicles. These vehicles have found uses in construction, large campuses (government, university, and industrial), agriculture, cattle ranches, amusement parks, and replacements for golf carts. Major mini-truck manufacturers and their brands include: Daihatsu Hijet , Honda Acty , Tata Ace , Mazda Scrum , Mitsubishi Minicab , Subaru Sambar , and Suzuki Carry . Light trucks are car-sized (in
310-401: A common construction: they are made of a chassis , a cab , an area for placing cargo or equipment, axles , suspension and roadwheels , an engine and a drivetrain . Pneumatic , hydraulic , water , and electrical systems may also be present. Many also tow one or more trailers or semi-trailers. The "cab", or "cabin" is an enclosed space where the driver is seated. A " sleeper " is
372-711: A compartment attached to or integral with the cab where the driver can rest while not driving, sometimes seen in semi-trailer trucks. There are several cab configurations: A further step from this is the side loading forklift that can be described as a specially fabricated vehicle with the same properties as a truck of this type, in addition to the ability to pick up its own load. Most small trucks such as sport utility vehicles (SUVs), vans or pickups , and even light medium-duty trucks in North America, China, and Russia use gasoline engines (petrol engines), but many diesel engined models are now being produced. Most of
434-580: A factory to the nearest railway station. The first semi-trailer appeared in 1881, towed by a steam tractor manufactured by De Dion-Bouton . Steam-powered wagons were sold in France and the United States until the eve of World War I , and 1935 in the United Kingdom, when a change in road tax rules made them uneconomic against the new diesel lorries. In 1895, Karl Benz designed and built
496-406: A ladder if tipped on end. The rails consist of a tall vertical section (two if boxed) and two shorter horizontal flanges. The height of the vertical section provides opposition to vertical flex when weight is applied to the top of the frame (beam resistance). Though typically flat the whole length on heavy-duty trucks, the rails may sometimes be tapered or arched for clearance around the engine or over
558-491: A limited range of trucks and buses with a single 105 CV engine, taking advantage of the economies of scale, which proved unsuccessful. In 1953, the strategy was changed and Renault decided to acquire rival manufacturers, starting with Somua and Latil . The company Saviem was formed in October 1955 by the merger of Renault's trucks and buses manufacturing operations with Somua and Latil and both Schneider (owner of Somua) and
620-420: A manual transmission with synchromesh (synchronizers). Bigger trucks often use manual transmissions without synchronizers, saving bulk and weight, although synchromesh transmissions are used in larger trucks as well. Transmissions without synchronizers, known as "crash boxes", require double-clutching for each shift, (which can lead to repetitive motion injuries), or a technique known colloquially as "floating",
682-545: A manual transmission, while conventional automatic or automated manual transmissions would have anything from 5 to 12 gears. Almost all heavy truck transmissions are of the "range and split" (double H shift pattern) type, where range change and so‑called half gears or splits are air operated and always preselected before the main gear selection. A truck frame consists of two parallel boxed (tubular) or C‑shaped rails, or beams, held together by crossmembers . These frames are referred to as ladder frames due to their resemblance to
SECTION 10
#1732782889737744-515: A maximum power output of 135 PS (133 bhp ; 99 kW ) at 2,900 rpm and a torque of 392 N⋅m (289 lb⋅ft ) at 1,600 rpm. It incorporated MAN-licensed direct injection technology and was only used on the SM6 and some military vehicles from 1970 onwards. In 1970, the SM range mounted the 797 and 798 (also called 597-05 and 598) engines, derived from the 597. The 797 (introduced in 1970)
806-407: A method of changing gears which does not use the clutch, except for starts and stops, due to the physical effort of double-clutching, especially with non-power-assisted clutches, faster shifts, and less clutch wear. Double-clutching allows the driver to control the engine and transmission revolutions to synchronize so that a smooth shift can be made; for example, when upshifting, the accelerator pedal
868-510: A more uncertain origin, but probably has its roots in the rail transport industry, where the word is known to have been used in 1838 to refer to a type of truck (a goods wagon as in British usage, not a bogie as in the American), specifically a large flat wagon. It might derive from the verb lurry (to carry or drag along, or to lug) which was in use as early as 1664, but that association
930-529: A revised design, new buses and coaches and, in 1964, a S range of medium duty trucks (with Renault and Perkins engines), unveiled at the Paris Motor Show. In January 1961, Saviem took control of the bus manufacturer Floirat , based at Annonay . That year, Saviem signed a cooperation agreement with Henschel-Werke . In 1962, Pierre Dreyfus decided to expand the European partnerships of Saviem and
992-401: A roof and floor, used for transporting fresh and frozen cargo such as ice cream, food, vegetables, and prescription drugs. They are mostly equipped with double-wing rear doors, but a side door is sometimes fitted. Refuse trucks have a specialized body for collecting and, often, compacting trash collected from municipal, commercial, and industrial sites. This application has the widest use of
1054-547: A rotating drum on an inclined axis, rotating in one direction to mix, and in the other to discharge the concrete down chutes. Because of the weight and power requirements of the drum body and rough construction sites, mixers have to be very heavy duty. Dual drive/Steer trucks are vehicles used to steer the rear of trailers . Dump trucks ("tippers" in the UK) transport loose material such as sand, gravel, or dirt for construction. A typical dump truck has an open-box bed, which
1116-709: A six-axle truck may have a maximum weight of 44 t (97,000 lb) or more. Off-road trucks include standard, extra heavy-duty highway-legal trucks, typically outfitted with off-road features such as a front driving axle and special tires for applications such as logging and construction, and purpose-built off-road vehicles unconstrained by weight limits, such as the Liebherr T 282B mining truck. Australia has complex regulations over weight and length, including axle spacing, type of axle/axle group, rear overhang, kingpin to rear of trailer, drawbar length, ground clearance, as well as height and width laws. These limits are some of
1178-570: A torque of 455 N⋅m (336 lb⋅ft) at 1,800 rpm. The SM5 used an evolution of the 712-01 engine used on the SG range. The transmission was a rear-wheel drive system of single shaft on the shorter chassis, and double shaft on the longer. The clutch was a manually-operated single-plate Verto Division Ferodo 12 LF 39 (except for the SM8 4x4). The gearbox was an horizontally-mounted 5-speed (4 synchronised) manual unit codenamed as 301. The suspension of
1240-411: A truck, of a trailer, from axle to hitch point, kingpin to rear of trailer, and turning radius are all regulated. In additions, there are special rules for carrying containers, and countries can set their own rules for local traffic. The United States Federal Bridge Law deals with the relation between the gross weight of the truck, the number of axles, the weight on and the spacing between the axles that
1302-622: A version of their Xebra electric tricycle (licensable in the U.S. as a motorcycle). Popular in Europe and Asia, many mini-trucks are factory redesigns of light automobiles, usually with monocoque bodies. Specialized designs with substantial frames such as the Italian Piaggio shown here are based upon Japanese designs (in this case by Daihatsu ) and are popular for use in "old town" sections of European cities that often have very narrow alleyways. Regardless of name, these small trucks serve
SECTION 20
#17327828897371364-573: A wide range of uses. In Japan, they are regulated under the Kei car laws, which allow vehicle owners a break in taxes for buying a smaller and less-powerful vehicle (currently, the engine is limited to 660 cc displacement). These vehicles are used as on-road utility vehicles in Japan. These Japanese-made mini-trucks that were manufactured for on-road use are competing with off-road ATVs in the United States, and import regulations require that these mini-trucks have
1426-427: Is hinged at the rear and lifts at the front, allowing the material in the bed to be unloaded ("dumped") on the ground behind the truck. Flatbed trucks have an entirely flat, level platform body. This allows for quick and easy loading but has no protection for the load. Hanging or removable sides are sometimes fitted, often in the form of a stakebody . Refrigerator trucks have insulated panels as walls and
1488-422: Is in neutral, it allows the engine speed to drop and synchronize engine and transmission revolutions relative to the road speed. Downshifting is performed in a similar fashion, except the engine speed is now required to increase (while the transmission is in neutral) just the right amount in order to achieve the synchronization for a smooth, non-collision gear change. "Skip changing" is also widely used; in principle,
1550-573: Is most often made as vans. Medium trucks are larger than light but smaller than heavy trucks. In the US, they are defined as weighing between 13,000 and 33,000 lb (5.9 and 15.0 t). For the UK and the EU the weight is between 3.5 and 7.5 t (7,700 and 16,500 lb). Local delivery and public service ( dump trucks , garbage trucks and fire-fighting trucks ) are normally around this size. Heavy trucks are
1612-461: Is mostly reserved for larger vehicles. In Australia and New Zealand, a pickup truck is frequently called a ute (short for "utility" vehicle), while in South Africa it is called a bakkie ( Afrikaans : "small open container"). In the United Kingdom, India, Malaysia, Singapore, Ireland, and Hong Kong lorry is used instead of truck , but only for the medium and heavy types, while truck
1674-469: Is not definitive. The expanded meaning of lorry , "self-propelled vehicle for carrying goods", has been in usage since 1911. In the United States, Canada, and the Philippines, "truck" is usually reserved for commercial vehicles larger than regular passenger cars, but includes large SUVs, pickups, and other vehicles with an open load bed. In Australia, New Zealand and South Africa, the word "truck"
1736-412: Is released and the clutch pedal is depressed while the gear lever is moved into neutral, the clutch pedal is then released and quickly pushed down again while the gear lever is moved to the next higher gear. Finally, the clutch pedal is released and the accelerator pedal pushed down to obtain the required engine speed. Although this is a relatively fast movement, perhaps a second or so while the transmission
1798-516: Is used almost exclusively to refer to pickups . Often produced as variations of golf cars , with internal combustion or battery electric drive , these are used typically for off-highway use on estates, golf courses, and parks. While not suitable for highway use some variations may be licensed as slow speed vehicles for operation on streets, generally as a body variation of a neighborhood electric vehicle . A few manufactures produce specialized chassis for this type of vehicle, while Zap Motors markets
1860-552: The European Union , vehicles with a gross combination mass of up to 3.5 t (3.4 long tons; 3.9 short tons) are defined as light commercial vehicles , and those over as large goods vehicles . Trucks and cars have a common ancestor: the steam-powered fardier Nicolas-Joseph Cugnot built in 1769. However, steam wagons were not common until the mid-19th century. The roads of the time, built for horse and carriages, limited these vehicles to very short hauls, usually from
1922-606: The Super Galion , in partnership with Avia . In 1975 Saviem, together with DAF , Volvo and Magirus-Deutz (soon after to become a part of Iveco ) became co-founder of the Club of Four cooperation to produce medium-sized trucks. At the same time, Saviem signed an agreement with DAC in Romania to provide engines for their new 6135 . The same year Saviem also acquired Sinpar and completed, together with Fiat and Alfa Romeo,

1984-468: The cab-over configuration in North America, to provide better maneuverability in tight situations. They are also among the most severe-duty and highest GVWR trucks on public roads. Semi-tractors ("artics" in the UK) have a fifth wheel for towing a semi-trailer instead of a body. Saviem SM At the end of 1967, as part of an extended partnership with the German MAN , Saviem introduced
2046-422: The diesel engine did not appear in production trucks until Benz introduced it in 1923. The diesel engine was not common in trucks in Europe until the 1930s. In the United States, Autocar introduced diesel engines for heavy applications in the mid-1930s. Demand was high enough that Autocar launched the "DC" model (diesel conventional) in 1939. However, it took much longer for diesel engines to be broadly accepted in
2108-461: The phase-out of fossil fuel vehicles includes trucks. According to The Economist magazine "Electric lorries will probably run on hydrogen, not batteries, which are too expensive." Other researchers say that once faster chargers are available batteries will become competitive against diesel for all, except perhaps the heaviest, trucks. Small trucks use the same type of transmissions as almost all cars, having either an automatic transmission or
2170-541: The Blum family (owner of Latil) had stakes in the new company. Initially, the Saviem name was added besides the existing badges of the three forming companies but, from 1957 onwards, Saviem-LRS appeared as marque's name on the company's products (the acronym representing the former marques Latil, Renault and Somua), which was simplified to Saviem in 1960. In 1959, Saviem became a whole-owned subsidiary of Renault. The early range of
2232-512: The French heavy equipment manufacturer Richard-Continental in a bid to compete with Caterpillar . From 1963 to 1977, Saviem cooperated with MAN of Germany (in 1967 such cooperation was expanded). As part of the agreement, Saviem supplied cabs and in return, MAN supplied axles and engines. The result of this was the launch of the SM (Saviem-MAN) and JM truck ranges in France. Renault also introduced
2294-479: The SM (Saviem-MAN) ranges. They were made up of the namesake SM medium truck range using the 812 cab , derived from the cab used for the SG range ( Super Galion and Super Goélette ), and the heavier SM Europe range using the Europe/Espace cab. The commercial versions of the SM were discontinued in 1975, although versions for military use were still produced after that year. The SM range line-up included
2356-609: The SM5 (8.7-tonne GVW ), the SM6 (9-tonne GVW), the SM7 (10.95-tonne GVW) and the SM8 (12.3-tonne GVW). All the SM range (except for the SM5) initially used the 597 engine manufactured at Saviem's Limoges plant, and later its evolutions: the 797 and the 798. The 597 was introduced in 1967, and it was also used for trucks of the MAN's medium range. It was a 5.27-litre atmospheric straight-six unit with
2418-545: The US, no more than 13,900 lb (6.3 t)) and are used by individuals and businesses alike. In the EU they may not weigh more than 3.5 t (7,700 lb) and are allowed to be driven with a driving licence for cars. Pickup trucks , called utes in Australia and New Zealand, are common in North America and some regions of Latin America, Asia, and Africa, but not so in Europe, where this size of commercial vehicle
2480-558: The US: gasoline engines were still in use on heavy trucks in the 1970s. Electrically powered trucks predate internal combustion ones and have been continuously available since the mid-19th-century. In the 1920s Autocar Trucks was the first of the major truck manufacturers to offer a range of electric trucks for sale. Electric trucks were successful for urban delivery roles and as specialized work vehicles like forklifts and pushback tugs . The higher energy density of liquid fuels soon led to
2542-403: The axles. The holes in rails are used either for mounting vehicle components and running wires and hoses or measuring and adjusting the orientation of the rails at the factory or repair shop. The frame is usually made of steel , but can be made (whole or in part) of aluminum for a lighter weight. A tow bar may be found attached at one or both ends, but heavy tractors almost always make use of

2604-650: The case of refuse trucks , fire trucks , concrete mixers , and suction excavators . In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a " tractor ". The majority of trucks currently in use are powered by diesel engines , although small- to medium-size trucks with gasoline engines exist in North America . Electrically powered trucks are more popular in China and Europe than elsewhere. In
2666-442: The company consisted of small commercial vehicles derived of Renault's existing models (Goélette and Galion), new medium and heavy trucks with Alfa Romeo engines and Chausson support for the coach/bus production. With an aggressive market approach focussed in volume rather than quality, Saviem became the leader by sales in France. During the early 1960s the company introduced a renovated JL heavy and medium duty trucks range with
2728-733: The company received a large capital amount from the French State for recapitalisation and modernisation. It also got the Limoges factory, which manufactured diesel engines. Between 1963 and 1966, Saviem moved most of its production from the Paris area to Blainville-sur-Orne and Annonay. In 1967, the Blainville-sur-Orne factory produced 26,000 large goods vehicles and the Annonay factory 1,777 buses/coaches. In 1965, Saviem acquired
2790-537: The construction of a joint production facility for engines ( Sofim ) in Foggia , Italy, at a cost of US$ 250 million . In January 1968, the main Saviem factory at Blainville-sur-Orne was the setting for one of the first workers' protests that led to the French May . As a result of companies' reorganisation and a French State decision of unifying the heavy vehicle production in France, in 1975 Renault also acquired
2852-431: The decline of electric-powered trucks in favor of, first, gasoline, and then diesel and CNG-fueled engines until battery technology advanced in the 2000s when new chemistries and higher-volume production broadened the range of applicability of electric propulsion to trucks in many more roles. Today, manufacturers are electrifying all trucks ahead of national regulatory requirements, with long-range over-the-road trucks being
2914-464: The end of 1946, Renault abandoned the production of heavy trucks in view of its financial troubles, and the company lost the position of France's market leader which it had before World War II . However, the rapid development and production concentration on that sector made Renault to seek ways to enter into the market. In 1950, the Renault's technical chief, Fernand Picard, elaborated a plan to launch
2976-493: The first internal combustion truck. Later that year some of Benz's trucks were modified to become busses by Netphener . A year later, in 1896, another internal combustion engine truck was built by Gottlieb Daimler , the Daimler Motor Lastwagen . Other companies, such as Peugeot , Renault and Büssing , also built their own versions. The first truck in the United States was built by Autocar in 1899 and
3038-451: The former Cahen shipyards, Blainville was the only truck factory owned by Saviem from 1966 onwards. In May 1964, the French government donated to Saviem the Limoges factory, a manufacturing facility for aircraft engine parts. Limoges became the main engine assembly location of the company. Saviem-owned Richard-Continental had two factories in Lyon. Truck A truck or lorry is
3100-443: The heavier trucks use four-stroke diesel engines with a turbocharger and intercooler . Huge off-highway trucks use locomotive-type engines such as a V12 Detroit Diesel two stroke engine. A large proportion of refuse trucks in the United States employ CNG (compressed natural gas) engines for their low fuel cost and reduced carbon emissions. A significant proportion of North American manufactured trucks use an engine built by
3162-440: The highest in the world, a B-double can weigh 62.5 t (61.5 long tons; 68.9 short tons) and be 25 m (82 ft) long, and road trains used in the outback can weigh 172 t (169.3 long tons; 189.6 short tons) and be 53.5 m (176 ft) long. The European Union also has complex regulations. The number and spacing of axles, steering, single or dual tires, and suspension type all affect maximum weights. Length of

#17327828897373224-407: The largest on-road trucks, Class 8 . These include vocational applications such as heavy dump trucks, concrete pump trucks, and refuse hauling, as well as ubiquitous long-haul 4x2 and 6×4 tractor units . Road damage and wear increase very rapidly with the axle weight. The number of steering axles and the suspension type also influence the amount of the road wear. In many countries with good roads
3286-521: The last remaining major independent engine manufacturer ( Cummins ) but most global OEMs such as Volvo Trucks and Daimler AG promote their own "captive" engines. In the European Union, all new truck engines must comply with Euro VI emission regulations, and Euro 7 from the late 2020s has stricter exhaust limits and also limits air pollution from brakes and tires . As of 2019 several alternative technologies are competing to displace
3348-662: The most challenging. Truck is used in American English ; the British English equivalent is lorry. The first known usage of "truck" was in 1611 when it referred to the small strong wheels on ships' cannon carriages, and comes from "Trokhos" (Greek) = "wheel". In its extended usage, it came to refer to carts for carrying heavy loads, a meaning known since 1771. Its expanded application to "motor-powered load carrier" has been in usage since 1930, shortened from "motor truck", which dates back to 1901. "Lorry" has
3410-424: The operation is the same as double-clutching, but it requires neutral be held slightly longer than a single-gear change. Common North American setups include 9, 10, 13, 15, and 18 speeds. Automatic and automated manual transmissions for heavy trucks are becoming more and more common, due to advances both in transmission and engine power. In Europe, 8, 10, 12, and 16 gears are common on larger trucks with
3472-734: The truck and bus manufacturer Berliet from the Michelin group. In 1978, Berliet and Saviem were merged to form Renault Véhicules Industriels (RVI). Again, the old marque names were retained for two more years while the model lineups gradually were assimilated, and in April 1980 they were replaced by the name Renault, putting an end to the Saviem badging. In 1977, its last year as a separate company within Renault, Saviem manufactured 35,059 buses/coaches and trucks. Vénissieux and Saint-Ouen were Somua factories. Vénissieux continued producing trucks until 1962. Saint-Ouen assembled engines until that activity
3534-592: The truck can have on the Interstate highway system. Each State determines the maximum permissible vehicle , combination , and axle weight on state and local roads. Uniquely, the State of Michigan has a gross vehicle weight limit of 164,000 lb (74 t), which is twice the U.S. federal limit. A measure to change the law was defeated in the Michigan Senate in 2019. Almost all trucks share
3596-405: The use of diesel engines in heavy trucks. CNG engines are widely used in the US refuse industry and in concrete mixers, among other short-range vocations, but range limitations have prevented their broader uptake in freight hauling applications. Heavy electric trucks and hydrogen-powered trucks are new to the market in 2021, but major freight haulers are interested. Although cars will be first
3658-493: Was a 5.49-litre atmospheric straight-six engine with a power output (at launch) of 145 PS (143 bhp; 107 kW) at 2,900 rpm and a torque of 402 N⋅m (296 lb⋅ft) at 1,700 rpm. The 797 was used in the SM7 and SM8 models. The 798 (used only on some versions of the Saviem SM8 4x4 ) was similar to the 797, but it was turbocharged and had a power output of 170 PS (170 bhp; 130 kW) at 2,900 rpm and
3720-635: Was available with 5 or 8 horsepower (4 or 6 kW) engines. Another early American truck was built by George Eldridge of Des Moines, Iowa, in 1903. It was powered by an engine with two opposed cylinders, and had a chain drive A 1903 Eldridge truck is displayed at the Iowa 80 Trucking Museum, Walcott, Iowa. Trucks of the era mostly used two-cylinder engines and had a carrying capacity of 1.5 to 2 t (3,300 to 4,400 lb). After World War I, several advances were made: electric starters , and 4, 6, and 8 cylinder engines. Although it had been invented in 1897,
3782-473: Was completely transferred to Limoges in 1964 and later auto parts. Suresnes and Saint-Cloud were Latil factories. Suresnes slowly ceased production but was kept as the head office and research and development base for the company. The Argenteuil factory was a former Chausson bus/coach facility operated by Saviem since 1960. It produced parts for both Saviem and Chausson. The coach/bus factory since 1961, originally part of Floirat and Isobloc. Built in 1956 on

The company initially had various factories for vehicle production around France (mainly at the Paris area ) which came from its predecessors and Chausson , but it soon centred assembly on Blainville-sur-Orne (trucks) and Annonay (buses and coaches). Saviem formed partnerships with other manufacturers, leading to technology-sharing agreements. At
