Encyclopedia > Independent suspension

Independent suspension is broad term for any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump in the road) independently of each other. This is contrasted with a beam axle, live axle or deDion system in which the wheels are linked - movement on one side affects the wheel on the other side. Karl Benzs Velo (vélo means bicycle in French) model (1894) - entered into the first automobile race 2005 MINI Cooper S. An automobile (also motor car or simply car) is a wheeled passenger vehicle that carries its own motor. ... The front suspension components of a Ford Model T. Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. ... An axle is a central shaft for a rotating wheel or gear. ... Solid axle and Panhard rod on a 2002 Mazda MPV 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 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. ... A de Dion tube is an automobile suspension technology. ...


Most modern vehicles have independent suspensions on the front wheels. 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, multiple links, or wishbones. A swing axle suspension is a simple type of independent suspension used in automobiles. ... A Chapman strut is an automobile suspension device. ... A simple MacPherson strut suspension on the left front wheel of a rear-wheel drive vehicle. ... A trailing-arm suspension is an automobile suspension design in which one or more arms (or links) are connected between (and perpendicular to) the axle and the chassis. ... A multi-link suspension is a type of suspension design typically used in independent suspensions, using 3 or more lateral arms, and one or more longitudinal arms. ... A double wishbone suspension is an automobile independent suspension design using two parallel wishbone-shaped arms to locate the wheel. ...


Independent suspension typically offers better ride quality and handling characteristics, due to lower unsprung weight and the ability of each wheel to address the road undisturbed by activities of the other wheel on the vehicle. Independent suspension requires additional engineering effort and expense in development versus a live axle or beam axle arrangement. A very complex IRS solution can also result in higher manufacturing costs. Ride quality refers to the degree of protection offered vehicle occupants from uneven elements in the road surface, or the terrain if driving off-road. ... Car handling and vehicle handling is a description of the way wheeled vehicles perform transverse to their direction of motion, particularly during cornering and swerving. ... 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. ... Solid axle and Panhard rod on a 2002 Mazda MPV 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. ...


The key reason for lower unsprung weight relative to a live axle design is that, for driven wheels, the differential unit does not form part of the unsprung elements of the suspension system. Instead it is either bolted directly to the vehicle's chassis, or more commonly to a subframe. 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. ... In an automobile and other four-wheeled vehicles, a differential is a device, usually consisting of gears, for allowing each of the driving wheels to rotate at different speeds, while supplying equal torque to each of them. ... This does not cite its references or sources. ... A chassis (plural: chassis) consists of a framework which supports an inanimate object, analogous to an animals skeleton; for example in the construction of an automobile or of a firearm. ... A subframe is a structural component of a vehicle, such as an automobile or an aircraft, that uses a discrete, separate structure within a larger body-on-frame or unit body to carry certain components, such as the engine, drivetrain, or suspension. ...


The relative movement between the wheels and the differential is achieved through the use of swinging driveshafts connected via universal (U) joints, analogous to the constant-velocity (CV) joints used in front wheel drive vehicles. A universal joint A universal joint, U joint, Cardan joint or Hardy-Spicer joint is a joint in a rigid rod that allows the rod to bend in any direction. ... Cross-section through a typical outer CV joint (Saab 96) Constant Velocity Joints (aka 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. ... Front wheel drive is the most common form of engine/transmission layout used in modern passenger cars, where the engine drives the front wheels. ...


However, independent suspension has its downfalls. It is costly to maintain because the parts are more expensive. It is harder to work on since most work requires the removal of the entire front end of the vehicle. Lifting an IFS(Independent Front Suspension) vehicle requires a lot of custom fabrication, which includes quite a bit of cutting and welding which many are hesitant to do. If you are looking for an offroad vehicle, stray away from the IFS systems. They break down easier and are more expensive. They offer less traction and less offroad driving ability.

Double wishbone suspension - Wikipedia, the free encyclopedia (624 words)
A double wishbone suspension is an automobile independent suspension design using two parallel wishbone-shaped arms to locate the wheel.
The suspension consists of a pair of upper and lower lateral arms, roughly horizontal and of similar length.
The advantage of a double wishbone suspension is that it is fairly easy to work out the effect of moving each joint, so you can tune the kinematics of the suspension easily and optimize wheel motion.
