Chapman Strut
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. The characteristic feature of the Chapman strut is a long upright strut combining a coil spring and shock absorber, with a universal-jointed drive shaft itself forming the lower link of the suspension. Origins Stout Scarab The design's origin lies with William Stout's 1932 Stout Scarab. This rear-engined car used swing axle independent rear suspension, with long near-vertical coilover struts from high mounting points on the space frame chassis. Stout had also been an aircraft designer and considered that the long-travel oleo struts made, '' 'the airplane landing gear '' s' the easiest type of running gear for comfort yet devised.' '' The lower ends of the struts were attached to the swing axle casings by swivel bushes. Forward radius rods handled the longitudinal forces ...

Chevrolet Cadet
Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Motor Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM). Louis Chevrolet (1878–1941) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose", would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929 with the Chevrolet International. Chevrolet-branded vehicles are sold in most aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft ( Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goggomobil
Goggomobil was a series of microcars produced by Hans Glas GmbH in the Bavarian town Dingolfing between 1955 and 1969. Glas produced three models on the Goggomobil platform: the Goggomobil T sedan, the Goggomobil TS coupé, and the Goggomobil TL van. The engine was an air-cooled, two-stroke, two-cylinder unit originally displacing 250 cc, but later available in increased sizes of 300 cc and 400 cc. It had an electric pre-selective transmission built by Getrag and a manual clutch. The engine was behind the rear wheels. Suspension was independent all round using coil springs with swing axles. 214,313 sedans, 66,511 coupés, and 3,667 Transporter vans and pickups were built from 1955 to 1969. T sedan The Goggomobil T250 was introduced by Glas at the 1954 IFMA international bicycle and motorcycle show. The T250 was a conventional-looking two door sedan with a rear-mounted 245 cc air-cooled two-stroke straight twin engine. Design changes were made to th ...

Double Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped, L-shaped, or even a single bar linkage. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lotus 17
The Lotus 17 was a sports car racing model built by Lotus Cars in 1959. Designed by Len Terry,Setright, L.J.K., "Lotus: The Golden Mean", in Northey, Tom, ed. ''World of Automobiles'' (London: Orbis, 1974), Volume 11, p. 1227. it was built in response to the Lola Mk1 which was dominant against the previous Lotus model, the Eleven. It was replaced in 1960 by the Lotus 19. The Lotus 17 was Chapman's answer to the Lola Mk 1, which by late 1958, was beating the venerable (but by then a good few years old) Eleven with monotonous regularity. The Lola was smaller and lighter than the Eleven, and so Chapman's riposte was even smaller, even lighter, even more aerodynamic. It was designed by Len Terry based on Chapman's ideas and it incorporated a number of new features, although in fact was the last front-engined sports racing car Lotus made. Its rear suspension was the Chapman strut, first used on the single seat Lotus Twelve, the Elite Coupe and the Lotus 15. Its front suspension ...

Anti-roll Bar
An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns—independent of its spring rate in the vertical direction. The first stabilizer bar patent was awarded to Canadian inventor Stephen Coleman of Fredericton, New Brunswick on April 22, 1919. Anti-roll bars were unusual on pre-WW2 cars due to the generally much stiffer suspension and acceptance of body roll. From the 1950s on, however, production cars were more commonly fitted with anti-roll bars, especially those vehicles with softer coil spring suspension. Purpose and operation An anti-sway or anti-roll bar is intended to force each side of the vehicle to lower, or rise, to similar h ...

Lever Arm Shock Absorber
Lever arm shock absorbers were the first form of hydraulic shock absorber or damper used for car suspension. They appeared in the 1930s and were most commonly used in the 1950s and 1960s, but were replaced by telescopic shock absorbers in the 1970s. One of the earliest patents for a hydraulic lever arm shock absorber was awarded in 1925 to Georges de Ram, who was already an established maker of friction disk shock absorbers. Hydraulic shock absorbers, invented by Ralph Peo in 1930, appeared as a development to replace the previous friction disks. These had, at best, provided a constant damping force, no matter what the size or speed of the suspension movement. With a viscous device using hydraulic oil, the resistance force increased with speed, so providing better damping for larger suspension bumps. Rotary vane The first hydraulic shock absorbers were of the ''rotary vane pattern'', the so-called Houdaille shock absorbers. These consisted of a cylindrical oil-filled body, bo ...

Telescopic Shock Absorber
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). Description 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 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, the dissipated energy can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent Front Suspension
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump on the road) independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together. Most modern vehicles have independent front suspension (IFS). Many vehicles also have an independent rear suspension (IRS). IRS, as the name implies, has the rear wheels independently sprung. A fully independent suspension has an independent suspension on all wheels. Some early independent systems used swing axles, but modern systems use Chapman or MacPherson struts, trailing arms, multilink, o ...
