ABSTRACT:
A compound type planetary gear set lacking ring gears has been applied to a differential limiting apparatus for distributing driving force between left and right wheels of a vehicle. The driving force conveyed from an engine is inputted to a first sun gear through a differential case and dividedly transmitted to a second sun gear through first and second pinions composed of helical gears and to a carrier supporting the first and second pinions, respectively. The driving force conveyed to the second sun gear is transmitted to a left drive axle and the driving force conveyed to the carrier is transmitted to a right drive axle. When slipping occurs in the left or right wheels, the first and second pinions rotate around the first and second sun gears. The helix angles of the first and second pinions produce thrust forces which generate a differential limiting torque between the left and right drive axles.
