Abstract

A wheel suspension comprising a vehicle body, a wheel movably articulated on the vehicle body via a control arm assembly. A wheel carrier and at least one helical pressure spring which is supported on the vehicle body on the one hand and on the wheel carrier or the control arm assembly on the other hand. The spring stiffness of the vehicle body support referred to the wheel contact point of the wheel can be controlled so as to be variable. Use is made of a helical pressure spring assembly whose force action line deviates from the geometric spring center line. Furthermore, there are provided rotational means for the 3-dimensional adjustment of the force action line relative to the geometric spring center line.
