ABSTRACT:
A parallel-axis torque-proportioning differential has four pairs of planet gears arranged symmetrically-but-non-equiangularly about a common axis in two mirror-image gear sets separated by angular spacings adequate to permit access for C-clip assembly. A thrust-block, positioned between the opposed end faces of the sun/side gears, is not supported in a housing window but rather is supported on the outer circumferential surfaces of four planet gears, two from of each set, so that the housing window can be significantly larger than the thrust-block, thus increasing lubrication and lessening the cost and weight of the housing and reducing the weight of the required thrust-block. Also, the thrust-block may include two side-by-side mating members separated by a spring element to exert a preload force between the opposed end faces of the side gears.
