ABSTRACT OF THE DISCLOSURE In a propulsion unit for the driven axles of an electrically- powered rail vehicle, the torque of an electric propulsion motor is transmitted to the respective driven axle by way of a torque transmitting mechanism inclu- ding gears and couplings. A common housing in the form of a hollow beam is used to enclose the propulsion motor, a bearing system, and a transmission. Cut- outs are provided in the sides of the housing to allow space for the driven axles. In order to increase the flexural and torsional stiffness of the propul- sion unit, the hollow beam includes an annular end surface through which the propulsion motor and torque transmitting apparatus are inserted. The hollow beam not only forms a common housing or the propulsion components, but is a very stiff support element that reduces vibration and improves the running behavior of the propulsion unit.
