PURPOSE:To prevent erroneous function of clutch due to the liquid pressure boosted through centrifugal force by providing means for limiting the motion of clutch piston between the clutch piston and the clutch shaft. CONSTITUTION:Upon rotation of the clutch shaft 1 and the clutch piston mechanism 9, centrifugal force will function onto the liquid filled in the liquid chamber of the clutch pistons 19, 20 to push them toward the clutch mechanisms 7, 8. But since balls 30, 31 are fitted in the ball grooves 26, 27 of the clutch shaft through springs 28, 29, motion of piston is blocked by said balls 30, 31. Upon supply of operating liquid pressure, relatively high force will function onto the piston to enable normal clutching. |
