摘要：A V belt stepless variable transmission provided with a driving pulley comprisinga stationary conical disc fixed to a drive shaft and a movable conical disc axially movablewith respect to the drive shaft, a driven pulley comprising a stationary conical disc fixed toa driven shaft and a movable conical disc axially movable with repsect to the driven shaft,and an endless V belt running across both the pulleys, so that an interval between eachstationary conical disc and each movable conical disc is changed to thereby carry outstepless variable transmission, the driving pulley being provided with a tension adjustingmeans for mechanically giving to the movable conical disc thrust to meet input torque tothereby adjust tension on the V belt, and the driven pulley being provided with anhydraulic actuating cylinder for hydraulically driving the movable conical disc at the drivenpulley, so that a fluid is supplied or discharged to or from the hydraulic actuating cylinderso as to actuate the movable conical disc at the driven pulley, thereby controlling thepulley ratio.
