Abstract:
1. An assembly comprising: a differential having a differential housing, said differential containing a bevel ring gear, a miter gear carrier affixed to said bevel ring gear and a sun gear affixed to said miter gear carrier, wherein said miter gear carrier supports at least one miter gear, and wherein said miter gear carrier and said sun gear rotate with said bevel ring gear; a driveshaft coupled to a pinion gear that intermeshes with said bevel ring gear within said differential; a first axle having a bevel drive gear and an externally toothed spur gear affixed thereto, wherein said first axle extends into said differential, wherein said bevel drive gear intermeshes with said at least one miter gear in said miter gear carrier; an internally toothed spur gear set in a fixed position within said differential housing; an annular gear concentrically aligned with said internally toothed spur gear; a subassembly of planetary gears that interconnect said sun gear, said internally toothed spur gear, said annular gear and said externally toothed spur gear on said first axle, wherein said differential transfers rotational energy from said driveshaft to said first axle, therein causing said first axle to rotate at a second rotational speed when said driveshaft turns at a first rotational speed; and an electric motor that selectively turns said annular gear, therein selectively altering said second rotational speed of said first axle.
