A damping device for an active chassis of a motor vehicle axle in which a damping system interacts with each wheel of the axle, each of the damping systems having the following components: a damper having a double-acting hydraulic cylinder and a piston; a hydraulic pump and an electric motor, the hydraulic pump being a reversing pump that can be driven by the electric motor in different rotational directions to provide different delivery directions; a hydraulic unit comprising a hydraulic tank and a valve, the hydraulic pump and the hydraulic unit of the respective damping system interacting with the hydraulic cylinder of the respective damping system such that a movement of the piston in a first actuation direction or in a second actuation direction can be provided depending on the conveying direction of the hydraulic pump, the electric motors of the two damping systems are connected to a common control device and can be actuated by the common control device, a position sensor is associated with each electric motor for acquiring the rotor position of the respective electric motor, the position sensor is connected to the control device, at least one pressure sensor is associated with each hydraulic pump for acquiring the pressure, and the position sensor is connected to the control device. The pressure sensor is connected to the control device.

    一种用于机动车辆车桥的主动式底盘的减震装置,其中减震系统与该车桥的每个车轮相互作用,该减震系统中的每个减震系统具有以下组件:减震器,该减震器具有双作用液压缸和活塞;液压泵和电动马达,液压泵是换向泵,该换向泵能够由电动马达在不同的旋转方向上驱动以提供不同的输送方向;液压单元,该液压单元包括液压油箱和阀,该液压泵和相应减震系统的该液压单元与相应减震系统的液压缸相互作用,使得根据该液压泵的该输送方向能够提供活塞在第一致动方向上或在第二致动方向上的移动,两个减震系统的电动马达连接到公共的控制装置并能由公共的控制装置驱控,位置传感器与每个电动马达相关联,以获取相应电动马达的转子位置,位置传感器连接到该控制装置,至少一个压力传感器与每个液压泵相关联以获取压力,该压力传感器连接到该控制装置。
