<p>PURPOSE:To obtain reliable centrifugal hydraulic pressure removing mechanism with the simple structure by generating the centrifugal hydraulic pressure in the piston pressure receiving chamber and the oil chamber being established on the other side of the piston pressure receiving chamber against the piston. CONSTITUTION:The rotary clutch is constituted by the hub 5 which is incorporatedly rotated with input shaft 1, the clutch mechanism 8 to clamp or disconnect the hub 5 and the output shaft 11 being provided between them, and the piston 18 which clamps the clutch mechanism 8 by displacing by conducting the working oil into the piston pressure receiving chamber 21 between the output shaft 11 and the piston 18 which is incorporatedly rotated with the output shaft 11. The sealing ring 25 is inserted between the hub 5 and the piston 18 of the rotary clutch mentioned above to form the centrifugal oil hydraulic pressure chamber 26 which matches the centrifugal oil hydraulic pressure in the piston pressure receiving chamber 21 to form the balance piston type centrifugal oil hydraulic pressure eliminating mechanism. Then the oil port 26 for lubrication which is connected to the oil hydraulic pressure chamber 26 through the oil port 28 in the radius direction is provided at the center of the input shaft 1.</p> |
