Abstract
A friction transmission having at least one friction disc formed as a rotating presser cylinder of a piston firmly connected with the associated shaft, with load-dependent hydraulic generation of the pressing forces, where at least on one transmission shaft a sensor is arranged for the torque transmitted there. The sensor, due to a torque-dependent movement of at least two valve parts in relation to one another, generates a torque-dependent hydraulic pressure and the necessary load-dependent hydraulic pressing force is generated exclusively by this pressure.
