Abstract

A torsion bar spring arrangement for a wheel suspension of a motor vehicle includes an actuator arranged on a vehicle body or on a subframe and constructed to variably pre-tension the torsion bar spring arrangement, a coaxial first torsion bar spring having an output side that is connected by way of an output lever to a wheel suspension element of the wheel suspension, and a housing of the actuator supported on the vehicle body in at least one bearing location for movement in a circumferential direction and resiliently yieldingly supported on the vehicle body in the direction of torsional moments acting on the torsion bar spring by way of at least one spring element.
