Scania-Vabis L20
The Scania-Vabis L20/L60/L71 was a series of heavy duty trucks produced by Swedish automaker Scania-Vabis between 1946 and 1958. Scania-Vabis L20 Scania-Vabis’ first post-war model, the L10 had been introduced already in 1944. Two years later came the larger L20, with a six-cylinder variant of the company's module engine which had been introduced in the late 1930s. The truck was also offered with a trailing axle. This version was called the LS20, with an “S” for "support axle". The largest bogie vehicle had a payload capacity of 10.2 tonnes. Scania-Vabis L60 At the end of 1949, Scania-Vabis introduced a direct injected diesel development of their module engine. It had been designed in collaboration with British truck manufacturer Leyland Motors. With the new engine, the six-cylinder truck got its name changed to L60 and LS60 respectively. Otherwise the truck was mostly unchanged. In 1951 the old fashioned non-synchro four-speed gear box was replaced by a synchroni ...

Scania-Vabis
Scania AB is a major Swedish manufacturer headquartered in Södertälje, focusing on commercial vehicles—specifically heavy lorries, trucks and buses. It also manufactures diesel engines for heavy vehicles as well as marine and general industrial applications. Scania was formed in 1911 through the merger of Södertälje-based Vabis and Malmö-based Maskinfabriks-aktiebolaget Scania. Since 1912, the company has been re-located again to Södertälje after the merger. Today, Scania has production facilities in Sweden, France, the Netherlands, Thailand, China, India, Argentina, Brazil, Poland, Russia and Finland. In addition, there are assembly plants in ten countries in Africa, Asia and Europe. Scania's sales and service organisation and finance companies are worldwide. In 2012, the company employed approximately 42,100 people around the world. Scania was listed on the NASDAQ OMX Stockholm stock exchange from 1996 to 2014. The company is a subsidiary of Traton, part of the Vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailing Axle
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle ( wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating surface area and steam generatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tow Truck
A tow truck (also called a wrecker, a breakdown truck, recovery vehicle or a breakdown lorry) is a truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles. This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location. A tow truck is distinct from a car carrier trailer, which is used to move multiple new or used vehicles simultaneously in routine transport operations. History Ferdinand Porsche of Austro-Daimler developed an artillery tractor for the Austro-Hungarian army in 1908, the M 08. One of the batch was constructed as a recovery vehicle for the others, with a large winch on the rear platform. The wrecker (with lifting jib) was invented in 1916 by Ernest Holmes Sr. of Chattanooga, Tennessee, a garage worker who was inspired after he needed blocks, ropes, and six men to pull a car ou ...

Power Steering
A power steering is a mechanical device equipped on a motor vehicle that helps drivers steer the vehicle by reducing steering effort needed to turn the steering wheel, making it easier for the vehicle to turn or maneuver at lower speeds. Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly. Power steering can also be engineered to provide some artificial feedback of forces acting on the steered wheels. Hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system. These systems have a direct mechanical connection between the steering wheel and the linkage that steers the wheels. This means that power-steering system failure (to augment effort) still permits the vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Brake (road Vehicle)
An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad or brake shoe needed to stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, such as trucks, buses, trailers, and semi-trailers, in addition to their use in railroad trains. George Westinghouse first developed air brakes for use in railway service. He patented a safer air brake on March 5, 1872. Westinghouse made numerous alterations to improve his air pressured brake invention, which led to various forms of the automatic brake. In the early 20th century, after its advantages were proven in railway use, it was adopted by manufacturers of trucks and heavy road vehicles. Design and function Air brakes are typically used on heavy trucks and buses. Typical operating pressure is approximatel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear Box
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-synchronous Transmission
A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require the driver to manually synchronize the transmission's input speed (engine RPM) and output speed (driveshaft speed). Non-synchronous transmissions are found primarily in various types of industrial machinery; such as tractors and semi-tractors. Non-synchronous manual transmissions are also found on motorcycles, in the form of constant-mesh sequential manual transmissions. Prior to the 1950s and 1960s, most cars used constant-mesh (and also sliding-mesh) but non-synchronous transmissions. History Most early automobiles were rear-engined, using a single-speed transmission and belt-drive to power the rear wheels. In 1891, the French Panhard et Levassor automobile used a three-speed manual transmission and is considered to have set the template for multi-speed manual transmissions in motor vehicles. This transmission ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leyland Motors
Leyland Motors Limited (later known as the Leyland Motor Corporation) was a British vehicle manufacturer of lorries, buses and trolleybuses. The company diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. It gave its name to the British Leyland Motor Corporation, formed when it merged with British Motor Holdings in 1968, to become British Leyland after being nationalised. British Leyland later changed its name to simply BL, then in 1986 to Rover Group. After the various vehicle manufacturing businesses of BL and its successors went defunct or were divested, the following marques survived: Jaguar and Land Rover, now built by Jaguar Land Rover owned by TATA Motors; MG, now built by MG Motor, and Mini, now built by BMW. The truck building operation survived largely intact as Leyland Trucks, a subsidiary of Paccar. History Beginning Leyland Motors has a long history dating from 1896, when the Sumner and Spurrier fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Scania-Vabis L10
The Scania-Vabis L10/L40/L51 was a series of trucks produced by Swedish automaker Scania-Vabis between 1944 and 1959. Scania-Vabis L10 During the Second World War Scania-Vabis’ entire production went to the Swedish Armed Forces and other public institutions. The company designed a new generation of trucks for post war times, when the pent-up demand for new trucks was expected to boom. The first post-war model, L10, was introduced in 1944.Scania Group - history It was the first Scania-Vabis truck with .

Scania-Vabis 335
The Scania-Vabis 335/345/355 was a series of heavy duty trucks produced by Swedish automaker Scania-Vabis between 1931 and 1944. Scania-Vabis 335 In 1931 Scania-Vabis presented a larger version of its standard truck, called the 335. The truck had a payload capacity of 4 to 5 tonnes and was sold with a six-cylinder engine in petrol or Hesselman version. In 1936 the truck was modernized with a more streamlined front with a slightly sloping radiator cover. More importantly the engine and cab was moved forward so that the engine was mounted above the front axle. This meant increased payload capacity with a longer loading platform and a better distribution of axle loads. From 1936 onwards the truck was offered with Scania-Vabis’ first pre-chamber diesel engine. Sales to private customers ceased at the outbreak of the Second World War. All production went instead to the Swedish Armed Forces and other public institutions. Most engines were converted to run on wood gas. The lo ...
