  • Pressure regulation of speed sensing electronic limited slip differential for axles
    Patent number: 6789657
    Abstract: A clutch pack actuation system for compressing the annular clutch pack of a limited slip differential includes a pump which can provide a supply of pressurized fluid, an annular member provided between the pump and the annular clutch pack, and an annular piston which is slidable within the annular member. Together with the annular member, the annular piston defines a clutch pressure chamber adapted to receive the supply of pressurized fluid. A fluid return line, by which the pressurized fluid is discharged from the clutch pressure chamber, is provided, and a valve, through which the pressurized fluid is returned to a fluid reservoir, is disposed in the fluid return line. The valve includes an element which is electromagnetically actuated so as to produce a desired pressure in the clutch pressure chamber.
