Automotive suspension technologies Automotive suspension technologies Active Body Control, or ABC, is a fully- active suspension, by Mercedes-Benz, that allows to control the vehicle body motions and therefore virtually eliminates body roll in many driving situations including cornering, accelerating, and braking. ...more on Wikipedia about "Active Body Control"
Automatic Leveling System are suspension system that automatically adjusts front and rear ride heights to compensate for changes in axle load. ...more on Wikipedia about "Automatic Leveling System"
An axle is a central shaft for a rotating wheel or gear. In some cases the axle may be fixed in position with a bearing or bushing sitting inside the hole in the wheel or gear to allow the wheel or gear to rotate around the axle. In other cases the wheel or gear may be fixed to the axle, with bearings or bushings provided at the mounting points where the axle is supported. Sometimes, especially on bicycles, the latter type is referred to as a spindle. ...more on Wikipedia about "Axle"
A beam axle is a suspension system, also called a solid axle, in which one set of wheels is connected laterally by a single beam or shaft. A live axle is a type of beam axle in which the shaft (or shafts, since live axles, while connected to move as a single unit, are seldom one piece) also transmits power to the wheels; a beam axle that does not also transmit power is sometimes called a dead axle. Beam axles are commonly used at the rear wheels of a vehicle. ...more on Wikipedia about "Beam axle"
In mechanical engineering, bushing can describe any of a variety of parts which allow one piece to pass through another. Plain bearings are also referred to as bushings. ...more on Wikipedia about "Bushing"
A Chapman strut is an automobile suspension device. Being a strut, it is designed to act as both a shock absorber (with an integrated coil spring) and a wheel location device. That is, it is designed to resist lateral forces. Chapman struts are the term for such a device when used on rear wheels, while the very similar MacPherson strut is used in front. (See MacPherson strut for more information.) ...more on Wikipedia about "Chapman strut"
A coilover is an automobile adjustable suspension device. It consists of a shock absorber or MacPherson strut with a coil spring encircling it. This provides for optimal damping without torsional loads. Coilovers are adjustable for ride height as well using a simple threaded spring perch similar to a nut. ...more on Wikipedia about "Coilover"
Constant Velocity Joints or homokinetic or CV joints allow a rotating shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front wheel drive and all wheel drive cars. However, rear wheel drive cars with independent rear suspensions typically use CV joints at the ends of the rear axle halfshafts. Audi Quattros use them for all four half-axles and on the front-to-rear driveshaft ( propeller shaft) as well, for a total of ten CV joints. ...more on Wikipedia about "Constant-velocity joint"
In automobiles, a control arm is a suspension link that connects a kunckle or wheel flange to the frame. One end of a control arm attaches to the knuckle or wheel flange, generally with either a ball joint or bushing. The opposite end of the arm, which attaches to a frame member, usually pivots on a bushing. ...more on Wikipedia about "Control arm"
A de Dion tube is an automobile suspension technology. It is a sophisticated form of non- independent suspension and is a considerable improvement over the alternative swing axle and Hotchkiss drive types. A de Dion suspension uses universal joints at both the wheel hubs and differential, and uses a solid tubular beam to hold the opposite wheels in parallel. Unlike an anti-roll bar, a de Dion tube is not directly connected to the chassis nor is it intended to flex. In suspension geometry it is close to the trailing beam suspension most recently seen on the front wheel drive Chrysler " K-cars", but without the torsional flexibility of that suspension. ...more on Wikipedia about "De Dion tube"
A double wishbone suspension is an automobile independent suspension design using two parallel wishbone-shaped arms to locate the wheel. Each wishbone (or arm) has two mounting positions to the chassis and one at the wheel hub. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double-wishbone designs allow the engineer to carefully control the camber angle of the wheel, and are commonly used in sports cars. ...more on Wikipedia about "Double wishbone suspension"
Hydactive Suspension is a development of Citroen Hydropneumatic suspension that can dynamically alter the cars suspension- Active Suspension. Most cars suspension is a compramise between comfort and handling, Hydractive is designed to provide both. Hydroactive suspension can activly switch between hard and soft modes depending on road conditions. ...more on Wikipedia about "Hydractive"
Hydragas is a type of automotive suspension system used in many cars produced by British Leyland and its successor companies. ...more on Wikipedia about "Hydragas"
Hydrolastic is a type of automotive suspension system used in many cars produced by British Motor Corporation (BMC) and its successor companies. ...more on Wikipedia about "Hydrolastic"
Hydropneumatic is the name given to a suspension system invented by Citroën and fitted to Citroën cars, as well as being adapted by other car manufacturers, notably Mercedes-Benz and Peugeot. It was also used on Berliet trucks. Similar systems are also used on some military vehicles. ...more on Wikipedia about "Hydropneumatic"
An independent suspension is an automobile suspension system that allows the wheels on an axle to move independently of each other. This is contrasted with a beam axle, live axle or deDion system in which they are linked. ...more on Wikipedia about "Independent suspension"
A leaf spring is a simple form of spring, commonly used for the suspension in wheeled vehicles. It is also one of the oldest forms of springing, dating back to medieval times. ...more on Wikipedia about "Leaf spring"
A live axle is a type of beam axle suspension system that uses the driveshafts that transmit power to the wheels to connect the wheels laterally so that they move together as a unit. ...more on Wikipedia about "Live axle"
A lower tie bar is an alloy/ steel bar that ties the lower suspension pick-up points of a vehicle together. It increases chassis rigidity by bracing the left and right lower-control-arm sheetmetal mounting points. The lower tie bar is designed to reduce the movement of the control arms and to stiffen the subframe to lessen the distortion of the lower suspension, especially during hard cornering; thus generally improving the handling and steering response of the vehicle much like a strut bar. The bar lowers ground clearance by some 30 mm on most aftermarket installations. ...more on Wikipedia about "Lower tie bar"
The MacPherson strut is a type of car suspension system widely used in modern vehicles, named after Earl S. MacPherson, an engineer who developed the design for the 1951 Ford Consul and later Zephyr. It can be used for both front and rear suspensions, but is usually found at the front, where it provides a steering pivot ( kingpin) as well as a suspension mounting for the wheel. Rear struts of a similar design are properly called Chapman struts. ...more on Wikipedia about "MacPherson strut"
A multi-link suspension is a type of vehicle suspension design typically used in independent suspensions, using three or more lateral arms, and one or more longitudinal arms. These arms do not have to be of equal length, and may be angled away from their 'obvious' direction. ...more on Wikipedia about "Multi-link suspension"
A Panhard rod is a component of a car suspension system that provides lateral location of the axle. Originally invented by the Panhard automobile company of France in the early twentieth century, this device has been widely used ever since. ...more on Wikipedia about "Panhard rod"
A radius rod (also called a radius arm or a torque arm) is a suspension member intended to control wheel motion in the longitudinal (fore-aft) plane. The link is connected (with a rubber or solid bushing) on one end to the wheel carrier or axle, on the other to the chassis or unibody of the vehicle. ...more on Wikipedia about "Radius rod"
To start with, standing on the right side of a car at rest, when the car starts to go forward, the wheel will go clockwise. This must be countered by the rear suspension taking up a counter-clockwise torque; otherwise, the body and frame of the car will strip itself off the rear suspension, whatever it is. It is that need which dominates several of the varieties of rear suspension. ...more on Wikipedia about "Rear suspension"
Cadillac introduced a Road Sensing Suspension system as part of the Northstar System in 1993. The system monitored damping rates of the shock absorbers every 15 milliseconds, selecting between two settings. ...more on Wikipedia about "Road Sensing Suspension"
