Abstract
A controllable differential having a clutch mechanism which transfers a predetermined amount of torque between a rotatable differential casing and a side gear when an initiating force is applied by an electronic actuator. A pair of sensors provide inputs to the electronic actuator which, in turn, actuates an electromagnet. A clutch mechanism is actuated by the electromagnet and applies an initiating force to the clutch mechanism to initially actuate the clutch mechanism when a predetermined relative rotational condition of the side gears is sensed. The application of the initiating force in combination with the interaction between engagement surfaces and between camming portions fully engages a clutch mechanism to transfer a predetermined controllable amount of torque.
