Abstract: Power transfer apparatus mountable intermediate a vehicular transmission and drive shaft comprising an input shaft spline mounted to one side of an inner split differential housing having a plurality of planetary gears rotatively mounted interiorly about the mating surfaces of the housing halves in engagement with a side gear. An output shaft mounted to the side gear rotatively extends through the differential housing at a bearing surface formed therein. Bearings journaled within a surrounding lubricant containing housing separately support the input and output shafts to rotate therein. Power is progressively transferred to the output shaft with the inability of the planetary gears to maintain pace with the input shaft.

Abstract: A positive drive differential which passes drive power directly to one wheel by splining one axle centrally to one side of a differential housing; and which side of the differential housing has no side differential gear. The other axle is splined into the only existing side differential gear and which also is geared to two small end differential gears or planetary gears that are journalled one-hundred and eighty degrees apart in the differential housing. The differential also contains a ring gear that is positively fastened to the differential housing and the differential housing is journalled in the ordinary manner to the axle housing by the means of ball-bearings. Similarly, the side differential gear is journalled to the differential housing by the means of ball-bearings.
