Abstract
A differential gear mechanism is provided of the type including a gear case (17), at least one pinion gear (21), and a pair of side gears (27 and 29). Clutch packs (43 and 45) are disposed between the side gears and the gear case and are operable, when engaged, to retard relative rotation between the gear case and the side gears. The mechanism includes a fluid pressure actuated displacement mechanism (57) which, in response to an external signal (71) transmits its output displacment into axial movement of a plurality of input members (81). The axial movemenat of the input members has an actuating travel X and an actuating force F. A pair of lever members (85) receives the axial input from the input members 81, with each lever member pivoting about a fulcrum member (91) to transmit to each of the clutches a clutch actuating movement having an actuating travel substantially less than the actuating travel X, and an actuating force substantially greater than the actuating force F.
