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 solely by way of a torque sensor that is disposed on the drive shaft and constitutes a pressure medium throttle that is adjustable as a function of the load, or in which a pressurizing valve preceding this torque sensor and controlled as a function of the transmission ratio is employed to additionally effect throttling as a function of the transmission ratio.
