Abstract
A locking differential assembly includes a differential case, a first output shaft and a second output shaft. A first side gear is non-rotatably coupled to the first output shaft and a second side gear is non-rotatably coupled to the second output shaft. A differential pin is also included, the differential pin having differential gears. The differential gears are rotatably supported by the differential case and drivingly engaged with the first and second side gears to allow differential rotation thereof. A lock mechanism is actuated when a first torque force is applied to a drive cam and a driven cam. Finally, an electromagnetic coil actuates a brake plate, wherein the brake plate comes into frictional with a brake disc. Furthermore, the electromagnetic coil is discontinuous around the circumference of the brake disc.
