Abstract

In a suspension of a vehicle wheel on a vehicle body, including a spring element for accommodating the compressive forces acting between the vehicle wheel and vehicle body and with a linear actuator for adjusting the kinematics and the distance between the vehicle wheel and the vehicle body, the spring element and the linear actuator include at least one tubular contraction element with at least one hydraulic or pneumatic or hydropneumatic pressure chamber enclosed in a casing, which is designed in such a way that a pressure rise in the pressure chamber widens the casing radially and shortens it axially.
