Abstract:
A differential for a part-time 4-wheel drive vehicle, comprising:a differential assembly disposed on a front axle shaft to allow front wheels to turn at different speeds when the vehicle is in a turn, said differential assembly including a differential case;an outer case for receiving power from a power transfer case via a front propeller shaft, the outer case being disposed around the front axle shaft while enclosing the differential case of the differential assembly, the outer case and differential case being independently rotatable; anda clutch lever assembly disposed between the outer case and the differential assembly to selectively couple the outer case to the differential assembly, the clutch lever assembly being mounted on the outer case so as to operate in a coupling direction to the differential case by centrifugal force generated when the outer case is rotated by power transmitted from the power transfer case.
