Abstract

A torsion bar system for a vehicle axle, in particular a rear axle, of a two-track vehicle, includes first and second rotary actuators, each of which is associated with a vehicle side, for an active suspension control. Each rotary actuator has at least one motor/gear unit with which torques can be generated and transmitted as actuating forces onto a wheel suspension element via an output lever. The motor/gear units of both rotary actuators are arranged in a common housing which is rotationally fixed to the vehicle body. The housing has at least two attachment points for bracing the vehicle body, wherein the attachment points are spaced from one another across a bearing distance, and the housing is mounted on the vehicle body in a rigid assembly via said attachment points.
