ABSTRACT:
An overrunning clutch comprising a clamping ring provided with clamping ramps and spring-loaded clamping rollers housed in pockets of a cage and associated with the clamping ramps, the clutch being switchable from a first indexing position into a second by rotation of the cage with respect to the clamping ring. The cage is characterized by either directly or with the help of an intermediate member on the one hand, and the clamping ring with projections and recesses on the other, engage in each other in such a way after the fashion of a screw thread that when the cage or the intermediate member, as the case may be, is axially displaced, the cage executes a movement of rotation with respect to the clamping ring.
