ABSTRACT:
In a drive system for motor vehicles having two drive axles, one of said driven axles is driven by means comprising a liquid friction coupling. In order to permit the use of a relatively small liquid friction coupling and to permit the interdependence of the speed difference between the coupling halves of the liquid friction coupling and the torque transmission capacity to be modulated within a large range with simple means, one coupling half of the preferably controllable liquid friction coupling is held against rotation, the other coupling half is connected to one torque-transmitting member of a planetary gear train having three torque-transmitting members, another of said three torque-transmitting members is arranged to be driven by the motor, and the third of said torque-transmitting members is connected to the axles to drive the same.
