Abstract
A limited slip differential, comprising a housing (10), two bevel side gears (15, 16), clutch assemblies (21, 22) disposed between the outermost ends of the side gears and the housing, two bevel planet gears (23, 24), thrust members (32) engaging the side gears, and spring means (37) operating on the thrust members to urge them into engagement with the side gears and cause frictional engagement in the clutch assemblies; wherein the bevel planet gears are rotatably supported on a shaft member (25) which extends transversely through the housing and also through a support member (30) which holds the thrust members (32) against rotation, the shaft member also loading the spring means when it is inserted. The arrangement enables the differential to have a housing in one piece, with a lateral opening or openings through which all parts can be introduced into the housing with assembly being completed by insertion of the planet gear support shaft member to load the spring means and hold the suport member in position.
