Abstract:
1. A device for active wheel alignment of wheels arranged on a wheel axle of a motor vehicle, said device comprising: two hydraulic body dampers arranged between a vehicle body and the wheel axle, each said body damper being configured as a differential cylinder having a cylinder and a dividing piston guided in the cylinder; a throttle which is arranged outside the cylinder of the body damper; a hydraulic servo unit for tread adjustment operably connected with the body dampers via hydraulic lines, 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, and a directional control valve arranged in one of the hydraulic lines between the throttle and the servo unit, wherein the directional control valve has a first switching position in which hydraulic fluid is conducted from the one side of the dividing piston via the throttle directly to the other side of the dividing piston, and a second switching position in which hydraulic fluid is conducted from the one side of the dividing piston via the throttle to the servo unit.
