Drive device for a hatch of a motor vehicle

摘要

The invention relates to a drive device for a hatch of a motor vehicle, wherein the drive device comprises two drive sections that are linearly moveable relative to each other between a retracted position and an extended position, wherein the drive sections are spring biased against each other into the extended position by a spring arrangement, wherein an end stop is provided to limit the drive motion between the drive sections to the extended position. It is proposed that the end stop comprises a damping arrangement with a deformation zone, wherein during a drive motion into the end stop, depending on the speed of the drive motion, the damping arrangement damps the drive motion mainly based on plastic deformation of the deformation zone.

1. A drive device for a hatch of a motor vehicle, wherein the drive device comprises two drive sections that are linearly moveable relative to each other between a retracted position and an extended position;
wherein the drive sections are spring biased against each other into the extended position by a spring arrangement; wherein an end stop is provided to limit the drive motion between the drive sections to the extended position; and wherein the end stop comprises a damping arrangement with a deformation zone, wherein during a drive motion into the end stop, depending on the speed of the drive motion, the damping arrangement damps the drive motion mainly based on plastic deformation of the deformation zone, wherein the plastic deformation of the deformation zone leaves the functioning of the drive device in view of driving the hatch unaffected.
