  • Patent number: 6840883
    Abstract: A differential mechanism with offset, self-aligning spherical side gears and wider side gear separation to provide differential mechanism that is less expensive and easier to assemble. The differential mechanism includes a centerpoint of one surface or gear that is offset from a centerpoint of the chamber or casing along an axle centerline in a direction away from an opposing surface or gear.
    Type: Grant

  • Patent number: 6652408
    Abstract: A direct drive differential containing a ring gear and a differential pin attached directly to the ring gear. This arrangement changes the load path through the differential case that allows for a new design to be created. The ring gear has a slot and the differential pin has a flat on the sides that mate together when assembled. The differential pin is round and the ring gear has a radius that mate together when assembled. The ring gear has a diameter machined into the inside ring diameter but allows a pin with slots to be assembled. The pin locks into place in the ring gear by rotating the pin during assembly. The ring gear has a through hole or is drilled and tapped and the differential pin has a hole therefore the two parts can be locked together in place.

  • Patent number: 6645113
    Abstract: A differential gear assembly for an automobile includes an annular ring gear, a differential case, a pair of side gears substantially axially aligned and spaced apart from each other and adapted to be supported by the differential case and to engage an axle shaft of the automobile, and a pair of differential pinion gears substantially axially aligned and spaced apart from each other, and adapted to engage the side gears. A differential pin is secured to and extends diametrically across the ring gear and is adapted to support the differential pinion gears in engagement with the side gears and to allow rotational movement of the differential pinion gears about the differential pin.
