Abstract
Abstract A limited slip differential includes at least a pair of pinion gears having a meshing relationship with a pair of side gears. The meshing relationship of one of the pinion gears with one side gear is out of phase with the meshing relationship of another pinion gear with the one side gear.

Claim 1
Independent Claim
180 words
A limited slip differential gear mechanism comprising a rotatable differential carrier, a plurality of pinion gears carried by said differential carrier and rotatable about their own axes relative to said differential carrier, a pair of side gears in continuous meshing engagement with said pinion gears, said side gears and pinion gears having gear teeth with a tooth profile which approxImates an involute curve, at least a pair of said pinion gears being mounted at diametrically opposite locations relative to said side gears, friction clutch means operatively associated with at least one of said side gears and said differential carrier for retarding relative rotation between said one side gear and said differential carrier, and each of said side gears having an odd number of teeth thereon providing an out-of-phase continuous meshing relationship of said pair of pinion gears with said side gears to thereby tend to provide a relatively uniform transmission of force between said side gears and said pinion gears upon relative rotation between said one side gear and said differential carrier against the influence of said friction clutch means.
