Title: Wedge friction clutch with onboard enable and disable function

Abstract: A wedge friction clutch with onboard enable and disable function, including: an axis of rotation; an inner race; an outer race located radially outward of the inner race; and a wedge assembly including at least one wedge plate located between the inner and outer races in a radial direction; at least one resilient element; and at least one piston. For a locked mode in which the inner and outer races are non-rotatably connected, the at least one resilient element is arranged to displace the at least one wedge plate in at least one first circumferential direction. For a free wheel mode in which the inner and outer races are independently rotatable with respect to each other, the at least one piston is arranged to displace the at least one wedge plate in at least one second circumferential direction.
