Abstract
A switchable clutch, including: a housing defining a pocket; a race arranged to receive torque; a pawl disposed in the pocket; a spring ring rotatable by an actuator to circumferential position with respect to the pawl; a ramp ring; and resilient element fixed to the spring ring and in contact with the pawl. In a free-wheel mode: the race is rotatable, with respect to the housing, in a first circumferential direction and in a second circumferential direction; and the resilient element urges the pawl radially outwardly out of contact with the race. In a one-way mode: the spring ring is in the circumferential position; the resilient element urges the pawl into contact with the race; and the pawl blocks rotation of the race, with respect to the housing, only in the first circumferential direction. In a locked mode, the ramp ring, the pawl, and the race are non-rotatably connected.
