摘要： A locking differential includes a pair of clutch members that are biased together by a resilient disc and friction pack assembly toward a cross pin that extends diametrically across the central chamber of a cylindrical housing driven by the drive shaft of a vehicle, thereby to drive a pair of side gears and the output shafts splined thereto. The cross-pin extends within operating cam grooves contained in the adjacent faces of the clutch members, such that when the rotational velocity of one output shaft exceeds that of the other by a predetermined amount, the friction pack assembly of the faster shaft is operated to a non-compressed condition, thereby to disengage the over-running output shaft from the drive shaft. The resilient disc devices may be annular wave springs, or resilient disc springs.

摘要： A differential includes a differential case; a side gear comprising a helical face gear; a helical pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the helical pinion. The pinion housing includes a first face; a second face opposing the first face; a first projection located on the first face; and a second projection located on the second face. In some embodiments, the differential further comprises an actuator configured for engagement with the pinion housing and a plurality of friction plates disposed between the actuator and the differential case. The pinion housing also includes an aperture or hole extending radially inwardly from an outer radial surface of the generally annular ring; and a channel extending from the first face to the second face, wherein the channel is substantially radially aligned with the aperture or hole.
