A differential includes a differential case; a side gear; a pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the 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. 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. In embodiments, the pinion housing includes one or more transfer formations configured to transfer torque from the differential case, and the pinion housing is configured to permit movement in an axial direction between a pair of side gears.

Limited slip differential using face gears and a pinion housing

A locking differential assembly includes a differential case defining an axis of rotation and a gear chamber. A first side gear is at a first end of the differential case. A second side gear is at a second end of the differential case opposite the first end for selectable rotation relative to the differential case. A solenoid is at the first end. The solenoid is directly wound onto a stator.

Locking differential assembly

Face gear

A locking differential assembly includes a differential case defining an axis of rotation and a gear chamber. A first side gear is at a first end of the differential case. A second side gear is at a second end of the differential case opposite the first end for selectable rotation relative to the differential case. At least two pinion gears are rotatably supported in the gear chamber in meshing engagement with the first side gear and the second side gear. A solenoid is at the first end. A plunger is selectably magnetically actuatable by the solenoid. A lock ring is selectably engagable with the second side gear to selectably prevent the side gear from rotating relative to the differential case. At least two relay rods are each connected to the plunger and to the lock ring to cause the lock ring to remain a fixed predetermined distance from the plunger.

A locking differential for a vehicle includes a rotatable housing and a differential mechanism supported in the housing. The differential mechanism includes a pair of clutch members wherein each of the clutch members presents an inwardly directed face. Each face includes a groove disposed in spacing relationship with respect to the other. A cross pin is received in each groove and is operatively connected for rotation with the housing. At least one biasing member is disposed between the clutch members and at least one wear pad is disposed at an end of the at least one biasing member to preload the at least one biasing member and to allow the at least one biasing member to be acted upon by only a single one of the clutch members.

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.

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.
