Abstract:
A damping arrangement of an active chassis for an axle of a motor vehicle. A damping system cooperates with each wheel of the axle, wherein each of the damping systems includes a damper, a hydraulic pump, and an electric motor. A hydraulic unit includes a hydraulic reservoir and valves, wherein the hydraulic pump and the hydraulic unit of the respective damping system cooperate with hydraulic chambers of the hydraulic cylinder of the respective damping system, such that, depending on the conveying direction of the hydraulic pump of the hydraulic unit, a movement of the piston in a first actuation direction or in a second actuation direction can be provided. The hydraulic pumps and the electric motors of both damping systems are combined to form a motor-pump unit. The motor-pump unit is fastened on both sides thereof to an axle carrier of the axle via two bearings.
