ABSTRACT:
A fluctuating gear ratio limited slip differential assembly is provided that includes a differential case and a pair of side gears disposed within the differential case. Each of the side gears may have a tooth with a first tooth flank. The differential assembly may further include a pinion shaft disposed within the differential case and a plurality of pinions supported by the pinion shaft. The pinions may be configured for engagement with the pair of side gears and each of the pinions may have a tooth with a second tooth flank. The first and second tooth flanks are configured to cause movement of the plane of action defining all contact points between the first tooth flank of the side gears and the second tooth flank of the pinions in a predetermined and/or controlled manner.
