ABSTRACT:
An infinitely variable cone disc transmission is disclosed in which the contact pressure forces are generated fully hydraulically and in which the contact pressure level is set either by way of a torque sensor that is disposed on the driven shaft and constitutes a pressure medium throttle that is adjustable as a function of the load and the transmission ratio, or by way of a pressurizing valve that is connected in series with this torque sensor and controlled as a function of the load.
