摘要：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. Surrounding the

gear case is a fluid pressure mechanism (71) including a cylinder (73) and a piston (75),both of which are rotationally stationary, but free to move axially. Adjacent the piston-cylinder assembly is a pair of reaction members (61 and 63) which transmit the axialdisplacements of the piston and cylinder, by means of members (57 and 59), to a pair ofload plates (53 and 55), such that the displacements exert axially-outward biasing forceson the side gears and on the clutch packs. Because the piston-cylinder assembly isexternal to the gear case, no rotating seals are required. In addition, because thehydraulic biasing forces act in the same direction as normal gear reaction forces, lesshydraulic force is required to actuate the clutch packs.
