Differential with limited slip and negligible prestressing in the conditions under a slight load

摘要

A geared differential of the limited slip type wherein spring or bias means, exerting a predetermined force, are interposed between the outer ends of the side gears and adjacent portions of the differential carrier housing for urging each side gear in a direction opposite to the direction of the axial force applied to the side gear, via the planetary gear, thereby normally tending to urge the clutch friction discs into disengagement as long as the predetermined force is greater than the axial force, thereby permitting a high differential bias under heavy drawbar conditions and a relatively low bias under light drawbar conditions.
