ABSTRACT:
An epicyclic planetary gear system having a plurality of partially meshed straight-cut primary and secondary planetary gears slidably mounted in a slidable differential housing and partially meshed with respective straight-cut input and output gears. Forward drive is achieved in each of a plurality of forward drive ranges by the respective coupling of the primary planet gears with the secondary planet gears and output gear and the secondary planet gears with the input gear. Reverse drive is similarly achieved for each of the forward ranges via the coupling of the input gear only with the secondary planet gears and the output gear only with the primary planet gears, while restraining rotation of the differential housing.
