Abstract (en)

[origin: CA1182341A] 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 flexibility 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 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.
