Abstract
A switchable ratcheting clutch achieves four different modes of operation based on a relative rotational position of a cam ring and an inner ring. In a central relative position, an outer ring can rotate freely in either direction with respect to the inner ring. In either extreme relative position, the outer ring is prevented from rotating in either direction relative to the inner ring. In intermediate positions one either side of the central position, the outer ring is permitted to rotate in one direction but not the other. A number of pawls are supported on the inner ring and pushed radially out of engagement with the outer ring by a spring on a spring cage. The spring cage moves with the cam ring between the one-way positions but the cam ring rotates relative to the spring cage when moving into the extreme positions.
