Abstract
A parallel-axis torque-proportioning differential includes four sets of planetary gear pairs mounted within a differential housing having exterior dimensions substantially identical to those presently being used for comparable prior art designs. The four planetary pairs are arranged in two planetary sets positioned symmetrically-but-non-equiangularly with the axes of the planet gears in a mirror-image relationship about the common axis of the sun/side gears and with each planetary set comprising two of the separate and distinct planet gear pairs. The two planetary sets are separated from each other by large angular spacings; and two large windows, which are positioned in circumferential alignment with each of said large angular spacings, facilitate lubrication and also provide appropriate access to accommodate C-clip assembly.
