Abstract
A differential mechanism for transmitting power from an input to an output includes a case containing a side gear, a locking member rotatably secured to the case and axially displaceable relative to the case. The locking member alternately engages the side gear to limit rotation of the side gear relative to the case, and disengages the side gear to permit rotation of the side gear relative to the case. An electromagnetic coil assembly is supported on the case for movement toward and away from the locking member. A first actuator including an electromagnetic coil is supported on the case for moving the locking member toward engagement with the side gear in response to energizing the coil. A second actuator urges the locking member away from engagement with the side gear.
