ABSTRACT:
The present invention provides a selectable one-way clutch including a generally annular race and a generally annular cam disposed radially about the race. The cam has a radially internal surface defining a first plurality of tapered face portions and a second plurality of tapered face portions. A first plurality of rollers are disposed radially between the race and the cam. A second plurality of rollers are disposed radially between the race and the cam, and are interposed between the first plurality of rollers. The first plurality of rollers are selectively engageable with the first plurality of tapered face portions to lock-up the selectable one-way clutch in a first direction, and the second plurality of rollers are selectively engageable with the second plurality of tapered face portions to lock-up the selectable one-way clutch in a second direction.
