Beschreibung
Zusammenfassung:	A differential gear mechanism of the limited slip type is provided, and includes a mechanism for locking up the differential gear set, and a mechanism for actuating the lockup mechanism. The actuating mechanism includes a flyweight mechanism (71) and a latch mechanism (111). The latch mechanism includes a latch member (115) defining a pair of latch surfaces (125 and 127). The latch mechanism further includes a frame member (113) and a weighted member (117) which is oppositely disposed from the latch member about the axis of rotation of the differential gear set. The weighted member is operable to move the latch mechanism, in opposition to the biasing force of a spring (123), along a straight, generally diametrally-oriented path, in response to increasing rotational speed of the differential gear mechanism. Such movement causes movement of the latch member from an operative position (FIGS. 4 and 5) to an inoperative position (FIG. 8), in which the latch member is incapable of engaging either of the flyweights to prevent rotation of the flyweight mechanism. The position and mode of operation of the weighted member is effective to reduce missed engagements of the actuating mechanism.
