摘要： 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 including 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 propulsion 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.

摘要： A longitudinal double-axle drive for an electric, track-bound, self-propelled vehicle is disclosed in which the electric propulsion motor is disposed longitudinally between two driving axles of the vehicle. The motor drives both driving axles via a respective angle transmission. In order to provide flexiblity for operating under different conditions, the electric propulsion motor is a double motor with two electrically independent rotors of equal length and a common stator comprised of two separate stator lamination stacks and a continuous stator winding. The side of each rotor facing its associated transmission is supported by an overhung arrangement from the transmission housing. Thereby, the two driving axles can rotate at different speeds without compulsion forces being generated.
