An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type of axle is referred to as a spindle.
A chassis is the load-bearing framework of a manufactured object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis.
The Lotus Elite name has been used for two production vehicles and one concept vehicle developed and manufactured by British automobile manufacturer Lotus Cars. The first generation Elite Type 14 was produced from 1957 until 1963 and the second generation model from 1974 until 1982. The Elite name was also applied to a concept vehicle unveiled in 2010.
A strut is a structural component commonly found in engineering, aeronautics, architecture and anatomy. Struts generally work by resisting longitudinal compression, but they may also serve in tension.
The Maserati Bora is a two-seat, rear mid-engine, rear-wheel drive sports car and grand tourer, manufactured by Maserati from 1971 to 1978. In common with other Maserati cars of the era, it is named after a wind, Bora being the wind of Trieste. The Bora was the company's first mid-engined street car and ended Maserati's reputation for producing fast but technologically out of date cars, also being the first Maserati with four wheel independent suspension. In contrast, competitor Lamborghini had first used full independent suspension in 1964.
The Y platform, or Y body, designation has been used twice by the General Motors Corporation to describe a series of vehicles all built on the same basic body and sharing many parts and characteristics. The first was for a group of entry-level compacts including the conventional front-engine compacts built by GM divisions Buick, Oldsmobile and Pontiac from 1961 to 1963. The second, and current, incarnation is used for a high-end rear-wheel drive sports-car platform from the 1970s through the 2000s.
The Chapman strut is a design of independent rear suspension used for light cars, particularly sports and racing cars. It takes its name from, and is best known for its use by, Colin Chapman of Lotus.
Body-on-frame, also known as ladder frame construction, is a common motor vehicle construction method, whereby a separate body or coach is mounted on a strong and relatively rigid vehicle frame or chassis that carries the powertrain and to which the wheels and their suspension, brakes, and steering are mounted. While this was the original method of building automobiles, body-on-frame construction is now used mainly for pickup trucks, large SUVs, and heavy trucks.
The Messerschmitt Kabinenroller was a series of microcars made by RSM Messerschmitt from 1953 to 1956 and by Fahrzeug- und Maschinenbau GmbH, Regensburg (FMR) from 1956 to 1964. All the Messerschmitt and FMR production cars used the Kabinenroller's monocoque structure, featuring tandem seating and usually a bubble canopy.
The General Motors K platform was the automobile platform designation used for the rear wheel drive Cadillac Seville midsize luxury models from 1975 to 1979.
The Bowin P3 is a monocoque racing car that was produced in 1968 by Bowin. The P3 was designed for the Australian National Formula and the Australian 1½ Litre Formula. After the capacity limit for Australian Formula 2 was increased from 1100cc to 1600cc at the beginning of 1969, the P3 found a new home in that class. The car was designed by John Joyce, founder of Bowin and assisted by Ray Parson, better known as a mechanic.
The Chevrolet Engineering Research Vehicle (CERV) is a series of Chevrolet experimental cars. Chevrolet Staff engineer, designer, and race car driver Zora Arkus-Duntov started development of the CERV I in 1959, and began work on the CERV II in 1963. Chevrolet chief engineer Don Runkle and Lotus' Tony Rudd discussed creating a new show car to demonstrate their engineering expertise in 1985; It would become the CERV III. Corvette chief engineer Dave Hill unveiled the CERV IV in 1993, a test vehicle for the 1997 C5 Corvette.
The following outline is provided as an overview of and topical guide to automobiles:
Backbone tube chassis is a type of automobile construction chassis that is similar to the body-on-frame design. Instead of a two-dimensional ladder-type structure, it consists of a strong tubular backbone that connects the front and rear suspension attachment areas. A body is then placed on this structure. It was first used in the English Rover 8hp of 1904 and then the French Simplicia automobile in 1909.
The GTM Coupé is a Mini based kit car dating back to 1967. GTM is an initialism for "Grand Touring Mini". The car was first shown at the 1967 Racing Car Show and soon afterwards went into production by the Cox brothers from their garage in Hazel Grove, Stockport as the Cox GTM. In 1969 the rights to the design and manufacturing were bought by Howard Heerey and the Cox part of the name was dropped. His father's company Midland Garage took over manufacture of the GTM. In April 1980 ownership changed again to GTM Engineering, who upgraded and continued to manufacture the Coupé until 1995.
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine.
A vehicle frame, also historically known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
Jaguar's independent rear suspension (IRS) unit has been a common component of a number of Jaguar production cars since 1961, passing through two major changes of configuration up to 2006 and last used in the Jaguar XK8 and Aston Martin DB7. This article concentrates on the first generation Jaguar IRS, which firmly established the marque's reputation for suspension sophistication, combining as it did smooth ride with excellent roadholding and low levels of noise, vibration, and harshness (NVH). The two generations overlap in time due to their being used in both full size and sports models that were updated at different times.
The Citroën Traction Avant is the world's first monocoque-bodied, front-wheel drive, mass-production car. A range of mostly 4-door saloons and executive cars, as well as longer wheelbased "Commerciale", and three row seating "Familiale" models, were produced with four- and six-cylinder engines, by French carmaker Citroën from 1934 to 1957. With some 760,000 units built, the Traction Avants were the first front-wheel drives made in such (six-figure) quantity.
A platform chassis is a form of vehicle frame / automobile chassis, constructed as a flat plate or platform, sometimes integrating a backbone or frame-structure with a vehicle's floor-pan.
