ABSTRACT:
A differential apparatus for a part-time four-wheel drive vehicle is provided. The differential apparatus includes an outer differential casing, an inner differential casing, a clutch member adjacent to the inner differential casing, a pair of dog clutches, a differential gear system arranged in the inner differential casing and an actuator body for actuating the clutch member. One of the dog clutches is connected with the inner differential casing, while the other of the dog clutches is formed on the clutch member. When the vehicle is traveling under two-wheel drive, the inner differential casing and the differential gear system are raced, while the outer differential casing and the clutch member do not race. Accordingly, it is possible to reduce the racing loss of these members and the noise caused by the racing loss.
