Abstract

An adjustable wheel suspension for the wheels of an axle of a motor vehicle is disclosed, wherein each wheel is guided by means of wheel guide elements and each wheel is operatively connected to an adjustable torsion bar, the torsion bars associated with the respective wheels being partially aligned with each other and each torsion bar being associated with an adjusting device that can be regulated and/or controlled by a controller for adjustment and each torsion bar being mounted on an auxiliary frame via its adjusting device and the controller. The adjusting devices and the adjusting mechanism are mounted in a common housing, which can be mounted on the auxiliary frame as an integral structural component.

First claim

What is claimed is:

1. An adjustable wheel suspension for wheels of an axle of a motor vehicle, comprising:
adjustable torsion bars respectively assigned to the wheels in one to one correspondence and operatively connected to the wheels, said torsion bars being partially aligned with each other and oriented in transverse direction of the vehicle;
a setting device for adjusting the torsion bars respectively assigned to each of the torsion bars and controllable via a controller, each of the torsion bars being respectively supported via the setting device and the controller on an auxiliary frame of the motor vehicle; and
a housing fastenable on the auxiliary frame as integral component and configured and dimensioned so as to provide sufficient stability to enable construction of the auxiliary frame without a transverse member,
wherein the setting devices, the controller, and the torsion bars are arranged entirely in the housing.

2. The adjustable wheel suspension of claim 1 , wherein the housing is configured as a closed profile.

3. The adjustable wheel suspension of claim 2 , wherein the closed profile has a circular, rectangular or triangular cross section.

4. The adjustable wheel suspension of claim 1 , wherein multiple shapings are formed on the housing, each having a horizontal bore, said auxiliary frame having horizontally oriented bores corresponding to the horizontal bore of the shapings, said housing being fastened on the auxiliary frame via a horizontally oriented threaded connection.
