Abstract: The invention concerns an overrunning clutch for receiving a shaft (10), said overrunning clutch comprising an outer ring having clamping surfaces, a cage (5) equipped with clamping rollers (6) and spring elements (8) for suspending the clamping rollers (6) being arranged in the outer ring. The clamping rollers (6) comprise a frustoconical bevel (9) on at least one end face, so that when the shaft (10) is not inserted, the enveloping circle diameter DHK of the conic frustum at its outer end is equal to or larger than the diameter DW of the shaft (10). This enables an automatic assembly of the entire overrunning clutch because the shaft (10) can be inserted without any problem into the cage (5).

Abstract: The invention concerns a switchable locking element freewheel with two concentric cage rings and locking elements lodged in pockets thereof, the cage rings being movable relative to each other for switching the freewheel. In order to make such a freewheel basically operable in two opposing directions and to provide simple switchover facilities herefor and also for cases in which switchability is required only in one direction, the relative movement of the two cage rings serving to switch the freewheel is an axial displacement which, with a view to any further embodiments of the freewheel, can be converted into a rotary movement.

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.

Abstract: A one-piece synthetic plastic cage for retention of clamping rollers in an overrunning roller clutch has two spaced-apart coaxial rims, axially parallel bars extending between the rims and defining roller pockets, and a discrete leaf spring for each bar. The springs are integral with one of the rims and are located radially outwardly of the corresponding bars so that they can bypass such bars by moving in the circumferential direction of the rims. One leg of each spring is integral with the one rim, and the other leg is integral with the one leg and has a free end which bears against the clamping roller in the corresponding pocket.
