Abstract

A differential assembly includes a case, a pair of pinion gears, a pair of side gears and an electrically operable coupling including an electromagnet. The coupling selectively drivingly interconnects one of the side gears and the case. The electromagnet of the coupling is axially moveable within the case to selectively place the differential assembly in an open or a locked condition.
