Abstract
A clutch, including: an inner race forming a pocket; an outer race; a pawl including a portion in the pocket; and a cage radially disposed between the inner race and the outer race. The cage includes a radially outer surface segment and a lift off bump stop extending from the surface segment. For a one-way mode, the inner race rotates, with respect to the outer race, only in one circumferential direction. For a first phase of the one-way mode, the inner race rotates in the circumferential direction and the pawl is arranged to be in contact with the outer race and free of contact with the lift off bump stop. For a second phase of the one-way mode: the inner TO race rotates in the first circumferential direction; and the pawl is arranged to be in contact with the lift off bump stop and free of contact with the outer race.
