Abstract
A one-way clutch, including: a plurality of first ramps with respective first face surfaces orthogonal to an axis of rotation or forming a first acute angle with the first line. The clutch includes at least one wedge plate including a smooth second outer circumference and a first inner circumference with a plurality of second ramps with respective second face surfaces orthogonal to the axis of rotation in the radial direction or forming a second acute angle with the second line. The clutch includes an outer race including a second inner circumference. The outer race is rotatable with respect to the inner race in a circumferential direction. For relative rotation of the outer race in the direction, at least one, but not all, first face surfaces is in contact with second face surface. Rotation of the outer race in an opposite circumferential direction locks the inner and outer races.
