In an infinitely variable cone pulley transmission the cone pulley pair on one of the two shafts (driving or driven) is pressed together by a helical coil spring and on the other shaft by a hydraulic force. On the hydraulically operated side the axially displaceable cone disc and the transmission shaft form together a cylinder and piston arrangement. A particularly compact dimensioning of the transmission and the control device is achieved by arranging the pressure pump housing immediately adjacent the transmission housing. The pressure pump housing contains in one block a slide valve for regulating the hydraulic pressure, lines for guiding the pressure liquid, first mechanical elements for automatically sensing and controlling the transmission ratio, and second mechanical means for manually overriding the automatically adjusted ratio. |
