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.
