A steering transmission for an electro-mechanical steering system for a vehicle includes an electric motor, a servo transmission, and an angle transmission for connecting a steering column of the steering system to a control stalk of the steering system. The angle transmission is a mechanically driven recirculating-ball transmission with a ball nut, which is engaged with a segment shaft of the steering transmission that is/can be connected to the steering stalk. A spindle of the recirculating-ball transmission is continuous. The spindle is connected to an output shaft of the servo transmission on one side. The servo transmission is/can be driven by the electric motor.

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.
