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, or wishbones.
Independent suspension allows wheels to rise and fall on their own without affecting the opposite wheel. Suspensions with other devices, such as sway bars that link the wheels in some way, are still classed as independent. Semi-dependent suspension is a third type. In this case, the motion of one wheel does affect the position of the other, but ...
A multi-link suspension is a type of independent vehicle suspension having three or more control links per wheel. [1] These arms do not have to be of equal length, and may be angled away from their "obvious" direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 [2] and later on their W201 and W124 series. [3] [4]
A key difference between the camber and toe changes of a twist beam versus a traditional independent suspension is the change in camber and toe is dependent on the position of the other wheel, not the car's chassis. In a traditional independent suspension, the camber and toe are based on the position of the wheel relative to the body.
Swing axle suspension characteristics: Camber change on bumps, "jacking" on rebound. A swing axle is a simple type of independent suspension designed and patented by Edmund Rumpler in 1903 for the rear axle of rear wheel drive vehicles. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow ...
A "semi trailing-arm" (or semi trailing-link) is a common form of independent rear suspension on automobiles, particularly those with front wheel drive (where it allows a flatter rear floor pan). Leading arms are similar horizontal arms, perpendicular to the axle, but connecting the wheels to the vehicle structure via pivot joints to the rear of
A short long arms suspension (SLA) is also known as an unequal-length double wishbone suspension. The upper arm is typically an A-arm and is shorter than the lower link, which is an A-arm or an L-arm, or sometimes a pair of tension/compression arms. In the latter case, the suspension can be called a multi-link, or dual-ball joint suspension.
When first introduced, it was relatively rare for British cars to have independently sprung rear wheels, [1] most production cars of the time using live rear axles. Independent suspension systems offer the advantage of lower unsprung mass to improve roadholding, and when properly designed, the ability to maintain the roadwheels perpendicular to ...
