Damping arrangement for an axle of a motor vehicle and motor vehicle

A damping arrangement for an axle of an active chassis of a motor vehicle, wherein damping systems of the damping arrangement interact with respective wheels of the axle, wherein each of the damping systems comprises:

• (a) a damper comprising a double-acting hydraulic cylinder and a piston, wherein the damper is configured to be coupled to a wheel suspension system of the respective wheel,
• (b) a hydraulic pump and an electric motor for driving the respective hydraulic pump, wherein the hydraulic pump is a reversing pump which is configured to be driven by the electric motor in different directions of rotation in order to provide different delivery directions, and
• (c) a hydraulic unit which comprises a hydraulic reservoir and valves, wherein the hydraulic pump and the hydraulic unit of the respective damping system interact with hydraulic chambers of the hydraulic cylinder of the respective damping system in such a manner that a movement of the piston in a first operating direction or in a second operating direction can be provided depending on the delivery direction of the hydraulic pump,
• wherein the electric motors of both damping systems are connected to a common control device and are configured to be actuated by the common control device,
• wherein the common control device has electronic assemblies which are distributed on different printed circuit boards in such a way that:
• (i) a first printed circuit board of the common control device has a low-voltage range with low-voltage assemblies and a high-voltage range with high-voltage assemblies which is galvanically isolated from the low-voltage range by isolating assemblies, wherein a CPU is included in the high-voltage assemblies of the first printed circuit board, and
• (ii) a second printed circuit board of the common control device has exclusively high-voltage assemblies, wherein the second printed circuit board is electrically connected to the high-voltage range of the first printed circuit board.
