Patent ID: 8167764

Claim:
A power transmitting device comprising: a differential case having a mounting hub; a gearset received in the differential case, the gearset comprising a side gear that is received in the differential case and rotatable about an axis; and a locking mechanism comprising an actuator, a first dog ring, a second dog ring and a thrust plate, the actuator being mounted about the mounting hub, the first dog ring being coupled for rotation with the side gear and having a set of first dog teeth, the second dog ring being non-rotatably but axially slidably coupled to the differential case, the second dog ring being formed of metal and having a set of second dog teeth, the thrust plate being formed of a polymer and being overmolded onto the second dog ring, the thrust plate extending through the differential case and abutting the actuator, wherein the actuator is selectively operable to translate the second dog ring such that the set of second dog teeth engage the first dog teeth to lock the side gear to the differential case.
