DRIVE
December 17, 2025
Damping arrangement for an axle of an active suspension system of a motor vehicle, wherein a damping system cooperates with each wheel of the axle, each damping system having: a damper which has 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, wherein the hydraulic pump and the hydraulic unit of the respective damping system cooperate with the respective hydraulic cylinder in such a manner that, depending on the delivery direction of the hydraulic pump, a movement of the piston in a first or in a second actuating direction can be provided, wherein the electric motors of both damping systems are arranged in a housing with axially aligned rotation axes and can be controlled by a common control device which has electronic components arranged on at least one circuit board, wherein the at least one circuit board extends laterally next to the electric motors parallel to the rotation axes of the electric motors, and wherein a DC-link capacitor of the control device extends from a board perpendicularly to the rotation axes of the electric motors into a free space between the electric motors.
