Abstract

A wheel suspension for a motor vehicle has a transverse control arm that can be attached to a vehicle body by way of bearings and a spring-elastic torsion bar assembly, and can be rotated about a longitudinal axis. The torsion bar assembly has a body spring that can be attached to the vehicle body with one end, and a transverse control arm spring that is attached to the transverse control arm with one end. The body spring and the transverse control arm spring are coupled with one another at their free ends. The transverse control arm spring and the body spring are coupled with one another by way of a setting element or a releasable connection, whereby the setting element or the releasable connection, respectively, allows rotation of the ends assigned to one another, for setting purposes.
