Abstract
An electronic locking differential that includes a movable electromagnet to selectively operate a dog clutch for locking a side gear to a carrier. The dog clutch includes a dog member having a plurality of legs that extend through leg apertures in the carrier. A cam mechanism is employed on the legs and the carrier to generate and apply a force to the dog member to maintain the dog member in an engaged position when torque is transmitted through the cam mechanism. The carrier is configured with an annular rib that surrounds a pocket. The annular rib has a frustoconical shape that matches that of a pole piece on the electromagnet. The electromagnet is received into the pocket when the electromagnet is operated and the dog member is in its engaged position.
