A power-dividing gear train assembly for motor vehicles includes a differential that outputs torque to two output shafts. The output torque applied to the output shafts is changeable by using a superimposing gear train, which comprises a plurality of epicyclic gear trains and is drivingly connected indirectly or directly with the output shafts. A drive motor is drivingly coupled to the superimposing gear train and the transmission ratio of the superimposing gear train is set such that an output shaft of the drive motor is still when the output shafts are rotating synchronously. To achieve a more precise and quicker-reacting redistribution of the drive torques, at least one epicyclic gear train, which reduces torque and cooperates with the differential, is connected upstream of the superimposing gear train. |
