Abstract
A differential gear unit provided with a limited slip mechanism which comprises a first cam element integral with one side gear, a second cam element axially slidable and rotatable on a hub portion of the side gear and being engaged with the first cam element to be axially displaced by its cam action when rotated relatively to the first cam element, and a friction clutch mechanism disposed between the second cam element and an internal end wall of a differential case to be engaged in response to the axial displacement of the second cam element. The limited slip mechanism further includes a clutch ring axially slidably mounted within the differential case in surrounding relationship with the second cam element, the clutch ring being formed at an inner periphery thereof with a conical surface for frictional engagement with a corresponding conical surface formed on an outer periphery of the second cam element. The clutch ring is operatively connected to a manually controlled penumatic actuator to be shifted between a disengaged position where it is disengaged from the second cam element and an engaged position where it is engaged with the second cam element to effect relative rotation…
