Air Suspension
Air suspension is a type of vehicle suspension powered by an electric or engine-driven air pump or compressor. This compressor pumps the air into a flexible bellows, usually made from textile-reinforced rubber. Unlike hydropneumatic suspension, which offers many similar features, air suspension does not use pressurized liquid, but pressurized air. The air pressure inflates the bellows, and raises the chassis from the axle. Overview Air suspension is used in place of conventional steel springs in heavy vehicle applications such as buses and trucks, and in some passenger cars. It is widely used on semi trailers and trains (primarily passenger trains). The purpose of air suspension is to provide a smooth, constant ride quality, but in some cases is used for sports suspension. Modern electronically controlled systems in automobiles and light trucks almost always feature self-leveling along with raising and lowering functions. Although traditionally called air bags or air bell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension (vehicle)
Suspension is the system of tires, tire air, spring (device), springs, shock absorbers and Linkage (mechanical), linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/Automobile handling, handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. The suspension is crucial for maintaining consistent contact between the road wheel and the road surface, as all forces exerted on the vehicle by the road or ground are transmitted through the tires' contact patches. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-levelling Suspension
Self-levelling refers to an automobile suspension system that maintains a constant ride height of the vehicle above the road, regardless of load. Purpose Many vehicle systems on a conventional vehicle are negatively affected by the change in attitude coming from changes in load - specifically a heavy load in the rear seat or luggage compartment. This change in attitude affects aerodynamic properties, headlight aim, braking, bumpers, shock absorption from the suspension and the vehicle's performance in a collision. Most of the braking power is on the front wheels of a vehicle, which means you will have more effective braking when more weight is over the front wheels. When the rear end has a heavy load, the braking is not as effective. The weight is concentrated on the rear end of the vehicle, and the rear brakes need to do all of the work. When braking quickly in this situation, the front brakes will be easier to lock up because of the lack of weight transfer to the front of th ...

Whitewall Tire
Whitewall tires or white sidewall (WSW) tires are tires having a stripe or entire sidewall of white rubber. These tires were most commonly used from the early 1900s to around the mid 1980s. Background The use of whitewall rubber for tire has been traced to a small tire company in Chicago called Vogue Tyre and Rubber Co that made them for their horse and chauffeur drawn carriages in 1914. Early automobile tires were made of pure natural rubber with various chemicals mixed into the tread compounds to make them wear better. The best of these was zinc oxide, a pure white substance that increased traction and also made the entire tire white. However, the white rubber did not offer sufficient endurance, so carbon black was added to the rubber to greatly increase tread life. Later, entirely black tires became available, the still extant white sidewalls being covered with a somewhat thin, black colored layer of rubber. Should a black sidewall tire have been severely scuffed against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadillac Eldorado
The Cadillac Eldorado is a luxury car manufactured and marketed by the Cadillac Motor Car Division of General Motors from 1952 until 2002, over twelve generations. The Eldorado was at or near the top of the Cadillac product line. The original 1953 Eldorado convertible and the Eldorado Brougham models of 1957–1960 had distinct bodyshells and were the most expensive models offered by Cadillac during those years. The Eldorado was never less than second in price after the Cadillac Series 75 limousine until 1966. Beginning in 1967, the Eldorado retained its premium position in the Cadillac price structure, but was manufactured in high volumes on a unique, two-door personal luxury car platform. The Eldorado carried the Fleetwood designation from 1965 through 1972, and was seen as a modern revival of the pre-war Cadillac V-12 and Cadillac V-16 roadsters and convertibles. Name The nameplate '' Eldorado'' is a contraction of two Spanish words that translate as "the gilded (i.e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Citroën Traction Avant
The Citroën Traction Avant () is the world's first mass-produced, semi-monocoque bodied, front-wheel drive car. A range of mostly four-door saloon (automobile), 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. Whilst front-wheel drive and four-wheel independent suspension had been established in production cars by Auto Union, and subsequently by others a few years prior – the Traction Avant pioneered integrating these into a mass-production car with a crash resistant, largely unitary, monocoque body. Additionally, the car was also an early adopter of Rack and pinion#Steering, rack and pinion steering. Although the car's name ("Traction Avant" literally means "front traction") emphasized its ...

Hydraulic Fluid
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery. Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic fluid used has zero compressibility. Functions and properties The primary function of a hydraulic fluid is to convey power. In use, however, there are other important functions of hydraulic fluid such as protection of the hydraulic machine components. The table below lists the major functions of a hydraulic fluid and the properties of a fluid that affect its ability to perform that function: Composition Base stock The original hydraulics fluid, dating back to the time of ancient Egyp ...

Paul Magès
Paul Ernest Mary Magès (1908–1999) is known for his invention of the first self-leveling automobile suspension, known as hydro-pneumatic suspension. This system replaced conventional steel springs with an adaptive system of hydraulic struts, resulting in a motoring experience that felt like no other automobile of the era. This suspension achieved its initial design brief: fast travel on poor road surfaces. This advantage is still noted today, especially in applications where ride quality is important, like ambulance design. His formal schooling was modest. He earned his National diploma (''Brevet d'Etudes du Premier Cycle''), a preparatory course for the Académie des Arts et Métiers in Marseille. At age 17, he sent his résumé to Citroën, one of the major automobile manufacturers in France, where he was hired to maintain equipment. In 1936 he became a technical draftsman, and in January 1942, CEO Pierre-Jules Boulanger assigned him to the development department to solve ...
