Abstract
A clutch drum is engaged to the rear part of a carrier of a center differential device. A clutch piston, which is rotated together with the rear drive shaft while allowing it to retractively move in a direction along a rear drive shaft, is provided within the clutch drum. Pinion shafts are protruded from the rear end face of the carrier to form protruded parts, which are confronted with the front end face of the clutch piston. A cam part, which is in sliding contact with the protruded parts, is formed on the front end of the clutch piston. When the carrier and the rear drive shaft relatively rotate, the protruded parts retractively move the clutch piston along cam crests of the cam part to press a clutch mechanism.
Claims24
A differential limiting device for a differential device, which limits relative rotations of a shaft for inputting and outputting drive power to a carrier and said carrier aligned with said shaft, said differential limiting device comprising:
- a clutch mechanism aligned with said shaft for engaging said shaft and said carrier;
- a ring-shaped clutch piston being rotated together with said shaft and being retractively movable in an axial direction of said shaft, thereby pressing said clutch mechanism;
- protruded parts protruded in the axial direction and each having an end that is confronted with said clutch piston;
- and
- cam crests formed on a surface of said clutch piston and confronted with said protruded parts, said cam crests being brought in sliding contact with the ends of said protruded parts respectively;
- wherein said protruded parts refractively move along the cam crests of said cam part to move said clutch piston in the axial direction when said carrier and said shaft relatively rotate.
