<p>PURPOSE: An electronically actuated automatic differential limiting device is provided to improve strength and torque transmission ability. CONSTITUTION: A differential gear mechanism includes a first output gear(25), and a cam and ramp actuator including first(59) and second(63) actuating plates, relative rotation of which results in axial movement of the first plate toward the first output gear. The mechanism includes an electromagnetic actuator operable to cause rotation of the second actuating plate, relative to a gear case(11). Both actuating plates are disposed external to an end wall(53) of the gear case. The first actuating plate has a plurality of actuation members extending axially through openings in the end wall. A locking plate(41) is disposed adjacent the first output gear, and is fixed to be non-rotatable relative to the gear case, but axially moveable therein. The output gear defines an array of teeth and the locking plate defines a plurality of recesses(43), adapted to receive the teeth, and lock the locking plate relative to the output gear whenever the cam and ramp actuator and the actuation members move the locking plate to a locked position.</p> |
