    Abstract: A differential gear mechanism, of either the locking or limited slip type, including a gear case (11) rotatably disposed within an outer housing (H) and means (37) to limit rotation of side gears (23,25) relative to the gear case (11), this means (37) including a member (41) which is axially moveable between a first position (FIG. 2) and a second position (FIG. 5). The mechanism includes a sensor assembly (95) and a sensor element (97) disposed adjacent the gear case (11). The axially moveable member (41) includes a sensed portion (89) surrounding an annular outer surface (11S) of the gear case, and disposed between the annular outer surface (11S) and the sensor element (97). Movement of the sensed portion (89) corresponding to changes within the mechanism between, for example, the unlocked and locked conditions, results in the sensor assembly (95) transmitting either a first or second electrical output. Thus, the present invention permits the vehicle control logic to know the condition of the differential mechanism and control certain other parts or functions of the vehicle accordingly.

    Abstract: The present invention relates to a limited slip differential with friction using a pressure generating device for performing a slip differential function of a vehicle and simultaneously, by limiting a portion of the slip differential function for movement of the vehicle when a big slip differential occurs, for rotating both wheels smoothly comprising a body section (12) having a fixed cover (11), a first side pinion gear (14) arranged inside of said body section (12) and connected with a driving shaft of a vehicle , a second side pinion gear (13) rotatably connected with a driving shaft of vehicle opposite to said first side pinion gear (14), a pair of differential pinion gears (15, 16) each of which is rotated in engagement with said first side pinion gear (14) and second side pinion gear (13), friction plates arranged at rear sides of said first side pinion gear (14) and second side pinion gear (13), and a pressure generating device (20) constructed such that its cover gear (22) and piston gear (25) engage with said second side pinion gear (13) and first side pinion gear (14), respectively, and can be displaced away from each other in a longitudinal direction of said device.
