<p>In the disclosed torque-proportioning type of automotive differential (10), a parallel-axis planetary gear arrangement interconnects the ends of a pair of coaxial drive axles (14, 16). The axles are received, respectively, by a pair of sun/side gears (20, 22) having helical teeth and confronting end faces and being interconnected by planetary sets of combination gears (44, 46; 48, 50; 52, 54). Each combination gear of each planetary set is provided with a narrowed shank portion intermediate two separate and distinct meshing portions in mesh with a respective one of the side gears and/or another combination gear of its respective planetary set. A washer component (56) is positioned with its opposite sides in engagement with the confronting end faces of the side gears and is restrained from rotation by a plurality of radially-extending support regions (58) positioned, respectively, between the shank portions of two combination gears of said planet gear sets. The sides of the washer component can be provided with radial grooves (62) to facilitate lubrication and/or with materials having differing coefficients of friction to modify the torque-bias characteristics of the differential.</p> |
