Abstract

The invention relates to a gear device (101) for a motor vehicle, for example for adjusting a camshaft in an internal combustion engine in order to influence the phase angle between the crankshaft and the camshaft. Such a gear device (101) must be constructed compactly and must also have a high wear resistance, in particular when reaching an end stop during the adjustment of the phase angle. For this purpose, the gear device (101) has a hydraulic end stop damping by means of a drive unit (103) and an output unit (105) with a communication chamber (113, 115).
