Abstract
A clutch, including: an inner race including a pocket; an outer race; and a pawl including a portion disposed in the pocket and pivotable within the pocket. In a locked mode of the switchable ratcheting clutch: the pawl contacts the outer race; and the pawl, the inner race, and the outer race are non-rotatably connected. In a one-way mode of the switchable ratcheting clutch: the pawl contacts the outer race; and relative rotation of the inner race around the axis of rotation and with respect to the outer race is enabled only in a first circumferential direction. In a freewheel mode of the switchable ratcheting clutch: the pawl is free of contact with the outer race; and the inner race is rotatable around the axis of rotation and with respect to the outer race in the first circumferential direction and in a second circumferential direction, opposite the first circumferential direction.
