Abstract
A wedge one-way clutch is provided for selectively transmitting torque between two components in one direction, and selectively locking rotation in another direction. The clutch has an inner race with a groove defined about its outer surface. The clutch has an outer race disposed radially outwardly from the inner race. The outer race has a sloped surface as part of a pocket. A wedge segment rests in the pocket. The wedge segment is moveable within the pocket, wherein the wedge segment has a taper or chamfer at its inner surface that engages with the groove in a slideable fashion. The wedge may also have a sloped surface that mates with and slides along the sloped surface of the outer race. The wedge can slide along the sloped surface, and along the inner race, so that the wedge wedges between the outer and inner races to lock them together.
