Abstract
An axle control element of a motor vehicle has a torsion spring system connected to a wheel control element via a rotary spring arm and fixedly supported on the vehicle body via a controllable actuator. The torsion spring system has a torsion spring rod nested inside a torsion spring tube. An actuator unit is spaced apart from the torsion spring system and is fixed on the vehicle body and a pivotally controllable drive lever is connected to the actuator unit. The drive lever is connected to a torsion spring tube, and an output lever is connected to a torsion spring rod and directly or indirectly via a coupling to the wheel control element. Alternatively, the drive lever is connected to a torsion spring rod, and the output lever is connected to a torsion spring tube and directly or indirectly via a coupling to the wheel control element.
