Abstract
Damping arrangement of an active chassis for an axle of a vehicle. A damping system cooperates with each wheel. Each of the damping systems has a damper having a double-acting hydraulic cylinder and a piston, a reversible hydraulic pump and an electric motor, and a hydraulic unit having a hydraulic reservoir and valves. The hydraulic pump and the hydraulic unit of the respective damping system cooperate with the hydraulic cylinder thereof such that, dependent upon the conveying direction of the hydraulic pump, a movement of the piston in a first actuation direction or in a second actuation direction can be provided. The electric motors of both damping systems are connected to and drivable by a common control device. A position sensor is associated with each electric motor to acquire the rotor position of the respective electric motor. A pressure sensor is associated with each hydraulic pump to acquire a pressure.
