Abstract:
A limited slip differential comprising:a differential case having a central axis, the differential case being connectable to an input shaft of an engine; a drive body coaxially disposed within the differential case; a planetary gear unit disposed around the drive body; a cam assembly for performing a differential action depending on a speed difference generated by planetary gear unit; and a multi-plate clutch assembly having outer plates connected to the cam assembly and inner plates connected to the drive body, wherein the cam assembly comprises a drive cam for moving in a circumferential direction with respect to the central axis by a speed difference between drive wheels, and a piston cam is urged toward the multi-plate clutch assembly when the drive cam is displaced in the circumferential direction to engage the inner and outer plates with each other; and wherein the outer plates are connected to the drive cam by a fixing member fixed on the differential case.
