Abstract:
1. An assembly comprising a differential case, a gear set and a locking device, the gear set including first and second side gears and a plurality of pinion gears, the pinion gears meshingly engaging the first and second side gears, the locking device including a first dog, a second dog, a return spring, a thrust member, and an actuator, the first dog including a plurality of first engaging features and being non-rotatably coupled to the second side gear, the second dog including a plurality of second engaging features and being non-rotatably but axially slidably engaged to the differential case, the return spring biasing the second dog away from the first dog, the thrust member extending through the differential case, the actuator being mounted about the differential case and comprising a plunger that is movable between a first position in which the first engaging features are decoupled from the second engaging features, and a second position in which the first engaging features are engaged with the second engaging features to thereby inhibit relative rotation between the second side gear and the differential case; wherein the plunger, the thrust member and the second dog are fixedly coupled to one another in an axial direction.
