Abstract: 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 the groove and is operatively connected for rotation with the housing. A dampening communication spring is disposed over an outer circumference of the clutch members and cooperates with the cross pin to control interaction of the clutch members.

Abstract: The present disclosure relates to a differential including a differential case adapted to be rotated about an axis of rotation. The differential also includes a cross-shaft operatively coupled to the differential case such that the cross-shaft and the differential case rotate together about the axis of rotation; left and right clutch actuators having opposing inboard sides between which the cross-shaft is positioned; and left and right axle hubs positioned on opposite sides of the cross-shaft. A left clutch pack prevents relative rotation between the left clutch actuator and the left axle hub about the axis of rotation when a left clutch engagement pressure is applied to the left clutch pack and a right clutch pack prevents relative rotation between the right clutch actuator and the right axle hub about the axis of rotation when a right clutch engagement pressure is applied to the right clutch pack. A clutch pre-load spring applies pressure to both the left and right clutch packs without applying pressure to the left and right clutch actuators. The clutch pre-load spring is positioned inboard of the left and right clutch packs. Contact between the cross-shaft and a ramp surface at the inboard side of the left clutch actuator causes the left clutch engagement pressure to be applied to the left clutch pack, and contact between the cross-shaft and a ramp surface at the inboard side of the right clutch actuator causes the right clutch engagement pressure to be applied to the right clutch pack.

A rotation limiting arrangement at the inboard sides of the left and right clutch actuators is provided for limiting relative rotation between the left and right clutch actuators about the axis of rotation. The rotation limiting arrangement includes a rotation limiter captured between first and second stop surfaces which cooperate to define a limited range of relative rotational movement between the left and right clutch actuators. The rotation limiter has a first location that makes line contact with the first stop surface. The rotation limiter also has a second location that makes line contact with the second stop surface.
