ABSTRACT:
A differential gear mechanism of the limited slip type is provided. The mechanism includes a clutch pack (35) and a cam mechanism (41) which are able to retard differentiating action of the differential gear means (19,23,25). A flyweight mechanism (51) is operable to actuate the cam mechanism, and to engage the clutch pack. The cam member (43) includes a cam surface (47) having alternating rising surface portions (61) and falling surface portions (63). These surface portions include pad portions (71,73), such that engagement with the mating cam surface (45) is limited to the area of the pad portion, thus making the transmittal of camming forces to the clutch pack more consistent and predictable.
