Abstract
The invention relates to a device for damping tractive and compressive forces which damps forces acting in both the tractive and compressive directions over a wide range, the device operating to be free of wear and having small overall length. The device has a damping system held in a housing and which has a resilient unit and a hydraulic damping arrangement, and a piston rod which is displaceable in the longitudinal direction relative to the housing of the damping system. Formed in an end region of the piston rod is a piston head which is held in a first hydraulic chamber of the hydraulic damping arrangement to be displaceable. If there is longitudinal movement of the piston head relative to the first hydraulic chamber, hydraulic fluid flows in a throttled manner, via a transfer-flow system, to a second hydraulic chamber of the hydraulic damping arrangement.
