The invention relates to a limited slip differential locking mechanism, mainly destined to be used in the motor vehicle field, playing the role of limiting the difference of the rotation speed between the driving wheels or between the driving axles of road motor vehicles when one of the wheels or axles has a rotation speed higher than necessary, said rotation speeds being caused by slipping on the rolling surface. According to the invention, the mechanism comprises an oil pump subassembly (A), a subassembly (B) for driving a multiple-disk clutch and a subassembly (C) for adjusting and controlling the pressure, the subassembly (A) consisting of a pump body (16) mounted on a housing (10) of the differential, in the pump body (16) there being mounted some inlet and discharge valves (7 and 14) respectively, a plate (12) for fastening the bearings, and some bearings (21) for supporting some shafts (4) for the differential outlet in order to put into contact some pistons (6) with a driving circular cam (20), worked on the opposite side of the toothing of outlet pinions (3) which drives them, the oil inlet valves (7) and discharge valves (14) being some ball valves, the springs (17) for returning the pumping pistons (6) playing the role of maintaining in permanent contact the pumping pistons (6) with the actuation circular cam (20) for achieving the oil intake, and a housing (5) is mounted on the pump body (16) playing the role of support for the subassembly (B) for actuating the multiple-disk clutch which comprises a pressure plate (8) having some annular sealing gaskets (18), said subassembly limiting the rotary motion between the outlet shafts in relation to the housing (10) of the differential, said process being controlled by the subassembly (C) for adjusting and controlling the pressure, installed in the subassembly (B) in a pressure plate (8), the subassembly (C) comprising a subassembly body (1), a piston (2) with variable cross-section, a cover (3) and a piston return spring (4). |
