Abstract
A device for active wheel alignment of wheels arranged on a wheel axle of a motor vehicle includes two hydraulic body dampers arranged between a vehicle body and the wheel axle. Each body damper is configured as a differential cylinder having a cylinder and a dividing piston which is guided in the cylinder. A throttle is arranged outside the cylinder of the body damper. Operably connected with the body dampers via hydraulic lines is a hydraulic servo unit, wherein hydraulic fluid is transferable via the throttle from one side of the dividing piston to the servo unit and from the servo unit via a returning one of the hydraulic lines back to another side of the dividing piston.
