Abstract
A damping system of an active chassis for one wheel of a motor vehicle. The system includes a double-acting hydraulic cylinder and a damper having a piston, which damper is couplable to a wheel suspension system for the wheel. The system also includes a hydraulic pump, and a hydraulic unit having a hydraulic reservoir and valves. The hydraulic pump and the hydraulic unit cooperate with hydraulic chambers of the hydraulic cylinder such that, depending on the direction of conveyance of the hydraulic pump, a movement of the piston in a first direction of actuation or in a second direction of actuation can be provided. The damper includes the hydraulic cylinder and the piston is designed such that, in the region of the damper, a flow of hydraulic oil via the piston or along the piston of the damper is at most 3 L/min.
