ABSTRACT:
In a driving power transmission, an input shaft is coaxially rotatably carried in a closed cylinder housing, extending through an operating piston received therein. The operating piston is bodily rotatable with the housing and axially movable relative to the housing and the input shaft. The piston defines at opposite ends thereof a clutch chamber and an axially thin circular space. A multiple disc clutch operable by the piston is provided in the clutch chamber for selectively transmitting a torque from the input shaft to the housing acting as an output shaft. A rotor with diametrically opposite blades is received within the axially thin circular space and is rotatable bodily with the input shaft for compulsorily displacing silicon oil filled in the circular space, so as to generate a pressure therein when relative rotation occurs between the housing and input shaft. For improved performance of the transmission, there are specified the volume of air which together with the silicon oil, is filled up within the axially thin circular space and the volume of air which, together with a lubrication oil, is filled up within the clutch chamber.
