Abstract
The invention relates to a gear device for a motor vehicle, as is used, for example, for adjusting a camshaft in a combustion engine in order to influence the phase angle between crankshaft and camshaft. Such gear devices have to be constructed compactly and also have to have high resistance to wear, in particular upon reaching end stops during adjustment of the phase angle. For this purpose, the gear device has hydraulic end stop damping by the drive unit and the output unit having communicating cavities.
