The spring suspension should absorb impacts from bumps in the road and convert them into oscillations. In connection with the shock absorbers , it causes a nearly uninterrupted road surface contact during acceleration, braking and particularly with uneven roads and when cornering.

How it works

The spring suspension connects 'unsprung mass' (wheels, brakes, portions of the suspension and steering) and 'sprung mass' (car body, drive- train and the remaining parts of the suspension and the steering). It works together with the spring suspension through the stabiliser, the tyres, and the seating. For the vehicle are not only up and down movements, also rotary motion, pitching (turning around the transverse axis), rolling (turning around the radial axis) and yawing (turning around the vertical axis) possible. Together with the shock absorbers and the suspension, the springs should ensure that the vehicle, maintaining maximum comfort for the driver, is controllable at all times.


All parts which connect sprung with unsprung mass, such as springs, shock absorbers and parts of the suspension, can only be proportionately, according to certain weight portions classed as one or the other. 06/09
