Abstract
A self-loading limited slip differential is disclosed including differential pinion and side gears having conical back surfaces, and torque-responsive wedge means operable by said pinion gears for applying frictional torque bias to the driven shafts via the side gears. The wedge means includes conical wedge elements that are displaced inwardly by the pinion gears upon the application of torque to the differential casing to force the side gears apart into frictional engagement with corresponding conical portions of the wall surfaces of the differential casing.
