The size, weight, and cost of a full-traction differential are significantly reduced by the synergism of several interrelated design features of a cartridge-like gear complex: (1) Each combination gear has only a shallow journal hole in each end of an otherwise solid gear body, being supported on mating hubs fixed to mounting plates slipped into a one-piece differential housing. (2) The solid worm-wheel portion of the combination gears has a deeper hour-glass shape. (3) Mating worm/worm-wheel teeth have a broad “supra-enveloping” contact pa...


1. A gear complex in a full-traction differential transferring rotational forces from an external power source to a pair of output axles mounted on an output axis, said differential having a housing that receives one end of each respective axle and is rotationally driven by said external power source; said gear complex, being supported within and rotating with said housing, comprising:a pair of side-gear worms, each side gear being mounted for rotation about said output axis and fixed to a respective one of said output axles;at least two sets of paired c...
