Gas spring damper device for motor vehicle, has resilience point comprising energy storage for storing portion of hydraulic energy, where energy is provided during insertion movement along path portion of spring path

摘要

The device (1) has a resilience point (21) comprising a gas compensation chamber that is filled with a compressible medium, and hydraulically assigned to working chambers (13, 15). A portion of hydraulic energy is stored by the point by a compressible medium, where the energy is changed by the point during immersion movement. The point comprises an energy storage for storing another portion of hydraulic energy, where the energy is provided during insertion movement along a path portion (35) of a spring path (23). The energy storage comprises a polymer spring (33).
