- 26 - TITLE PARALLEL-AXIS DIFFERENTIAL WITH TRIPLET COMBINATION GEARS ABSTRACT The preferred embodiments of the invention disclose an automotive torque-proportioning differential of the parallel-axis type having two planetary sets of either three or four combination gears in mesh with sun/side gears that receive respective vehicle axle ends. Each respective combination gear in each set is in meshing engagement with both (a) a respective one of the differential's two sun gears and (b) at least one other combination gear of its set. As compared with the planetary gearing of conventional differentials of similar size and torque-proportioning characteristics, the widely-separated sets of planetary gears occupy remarkably less interior space in the housing, permitting (i) the use of unconventionally large housing windows that significantly reduce the weight of the differential and greatly facilitate lubrication of the differential's gearing, and/or (ii) accommodation of C-clip assembly for the axle ends without increasing the exterior dimensions of the differential. In one embodiment, the center combination gear of each planetary set is designed with a larger diameter than the respective diameters of the two outer combination gears of the set.
