    Abstract: A damping system of an active chassis for a vehicle wheel. The damping 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. A hydraulic pump has a hydraulic reservoir and a hydraulic unit including 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 of the hydraulic unit, a movement of the piston in a first direction of actuation or in a second direction of actuation can be provided. The hydraulic pump and the damper are connected via the hydraulic unit and a tube-hose system including tubes and hoses. The hydraulic cylinder of the damper and the tube-hose system of the damping system feature a combined hydraulic capacity of between 9 mL/100 bar and 14 mL/100 bar.
