ABSTRACT:
A friction clutch device comprising a clutch spring capable of springing friction plates in a preset direction, a hydraulic device capable of generating oil pressure for likewise pressing said friction plates in said preset direction, and a release device which, when in inoperative conditions, permits the springing force of said clutch spring and the oil pressure of said hydraulic device to act as said pressing force with respect to said friction plates and which, when in operative conditions, effects the discharge of oil pressure from said hydraulic device and the release of the springing force of said clutch spring with respect to said friction plates. With this arrangement, the engaging force of the clutch device is obtained by the sum of the springing force of the clutch spring with respect to a pressure plate and the pressing force by use of oil pressure of the hydraulic device whereas the disengaging position is obtained by the release of the springing force of the clutch spring resulting from the operation of a release mechanism and the release of oil pressure. Thus, it becomes possible to increase the capacity of load while controlling the clutch operating force to the minimal value as needed. In addition, the present device is advantageous because the required engaging force can be secured by the clutch spring even if no oil pressure is present in the source of oil pressure.
