Abstract
A damping arrangement for an axle of an active chassis of a motor vehicle. A damping system interacts with each wheel of the axle, each damping system has the following: a damper having a double-acting hydraulic cylinder and a piston, a hydraulic pump and an electric motor for driving the hydraulic pump, a hydraulic unit having a hydraulic reservoir and valves. The hydraulic pump and the hydraulic unit of the respective damping system interact with the respective hydraulic cylinder in such a manner that, depending on the conveyance direction of the hydraulic pump, a movement of the piston can be provided in a first or in a second actuation direction. The electric motors of both damping systems are arranged with axially aligned rotational axes in a casing and can be regulated by a common control device which has electronic construction groups which are arranged on at least one circuit board.
