ABSTRACT:
A differential mechanism is disclosed including a pair of holdout rings each of which is angularly displaceable to an operable position for maintaining in a disengaged condition an associated overrunning or underrunning clutch member, characterized by the arrangement of the center cam member concentrically within the center driving member, together with the provision of a rotation limiting stop for limiting the extent of rotation of the holdout ring relative to the central driving member when the holdout ring is rotated from an inoperative condition toward an operative condition. In one embodiment, the stop comprises the side wall of a through slot (2e) contained in the inner periphery of the center driving member (2), which stop is engaged by the lateral surface (30e) of an axial projection (30c) of reduced width on the associated holdout ring lug (30b). In a second embodiment, each holdout ring lug (130b) has a generally rectangular configuration, and certain teeth (102m) on the center driving member have stepped teeth with portions of reduced height (102n) that extend radially inwardly between the slots, which reduced tooth portions have lateral surfaces that are engaged by the lugs (130b) to limit the extent of rotational displacement of each holdout ring relative to the central driving member. By providing the stop on the central driving member, a more accurate positioning of the holdout ring in the operative condition is achieved, thereby affording improved quality and reliability of the differential mechanism.
