Abstract
Unit for picking up a spare wheel of a vehicle. According to one implementation the unit includes a gear assembly configure to apply a torque on a drum supporting a cable, the gear assembly having a cam that wobbles as the gear assembly transmits the torque. A rotatable stop is situated adjacent a side edge of the cam and is configured to act on the edge of the cam to limit the travel of the cam during the wobbling movement. The stop has a first contact surface and a second contact surface with the edge of the cam configured to slide along the first contact surface as the drum is rotated in at least one direction by operation of the cam. A guide surface is provided to interact with the second contact surface to limit the rotation of the stop when the edge of the cam acts on the stop.
