ABSTRACT:
A differential gear assembly for vehicles is provided between a pair of drive axles (12), (14) are received in bores (10) formed in the sides of a differential housing (4), and wherein axially aligned worm or side gears (18, 18') are coupled to each axle end for meshing engagement with torque transfer gears (20) within said housing. A non-rotatable washer element (30) is inserted between confronting end faces of the side gears (18, 18') to reduce the sliding velocity between the washer and each side gear to one-half of the relative sliding velocity between the side gears, thereby reducing and/or controlling friction between the side gears and reducing differences in bias ratios associated with opposite directions of differentiation.
