ABSTRACT:
A differential having a differential case, a pair of side gears disposed in the differential case and a biasing element disposed between the side gears to force the side gears against the differential case, creating a torque bias between the side gears and the differential case. The torque bias may also include the torque bias between the biasing element and the side gears. In some embodiments, the differential may include washers disposed between the side gears and the differential case, so that the torque bias may be the sum of the bias created between the side gears and the biasing element, the side gears and the washer, and the washer and the differential case. In an alternative embodiment, the differential includes a pair of pinions rotatably engaging the side gears, wherein the biasing element applies a force to the pinion gears to create a torque bias on the pinion gears, thereby inhibiting the side gears from movement relative to each other until the pinion torque bias is overcome.
