Abstract
A drive apparatus for a closure element of a motor vehicle, including a tube defining an axis, a spindle disposed within the tube and configured to move from an extended position to a first retracted position and a second retracted position, a spindle nut disposed within the tube and operatively engaged to the spindle, a stop nut fixed to the spindle, and a damping element disposed between the spindle nut and the stop nut. The tube defines a first end stop face and the stop nut defines a second end stop face, and when the spindle is in the first retracted position, the damping element engages the first end stop face and is spaced apart from the stop nut.
