Abstract
A one-way clutch, including: an inner race including a first outer circumference with a first plurality of ramps and at least one wedge plate including: a first inner circumference with a second plurality of ramps; a second outer circumference; and a first plurality of slots: passing through material forming the at least one wedge plate in an axial direction; including respective first ends open to the second outer circumference; and including respective second ends radially outward of the first inner circumference and enclosed by the at least one wedge plate. The one-way clutch includes an outer race including a second inner circumference. The outer race is able to rotate with respect to the inner race in a first circumferential direction. Rotation of the outer race in a second circumferential direction, opposite the first circumferential direction, causes the rotation of the outer race to lock to rotation of the inner race.
