Definitions

  • the invention relates to a double-axle longitudinal drive for an electric rail locomotive, in which the electric drive motor arranged longitudinally between two drive axles drives both drive axles via an angular gear, the large wheel of which is connected to the drive axle via elastic couplings, the rotor shaft of the electric drive motor being directly in the pinion bearings of the Angular gear is mounted.
  • Such a double-axis longitudinal drive is known from DE-PS 25 14 265.
  • the otherwise usual end shields of the electric traction motor have been omitted, since the bearing shaft is mounted in the pinion bearings of the angular gear and thus in the gear housing.
  • at least one centering clutch which allows longitudinal displacements is provided in the known drive in the course of the rotor shaft.
  • further weight savings can be achieved by designing the drive motor without a housing.
  • double-axis longitudinal drives from DE-AS 26 06 807 that for flexible adaptation to the operating conditions, which sometimes include a different speed of the two drive axles, it is advantageous to design the electric drive motor which drives on both sides as a double motor.
  • This known double motor consists of two electrically independent runners of the same length and a common stator from two separate stator core packages of the same length with continuous stator winding. As a result, the two runners are subject to a common electrical undivided excitation, with a pure separation of the fluxes of the two runners and thus a clear magnetic decoupling.
  • both runners with the same length have the same speed / torque characteristic and can take up different speeds, so that in the event of slip phenomena that cannot be avoided, there are no constraining forces due to differences in wheel diameters or when cornering.
  • the rotors are each supported independently of one another with the aid of a central shaft and a hollow shaft surrounding them, the central shaft both mechanically coupling to one another.
  • the invention has for its object to obtain the flexible adaptation to the operating conditions with a simple construction and low weight of the traction motor in a double-axis longitudinal drive.
  • a double-axis longitudinal drive of the type described at the outset is designed in accordance with the invention in such a way that the electric traction motor is designed in a manner known per se as a double motor with two electrically independent rotors of the same length and a common stator from two separate stator core packages of the same length with continuous stator winding is and that each rotor is floating on one side in the angular gear. Due to the flying support of the two runners, there is no mechanical connection between them. This allows longitudinal displacements without the provision of a be special clutch. The centrifugal forces of the rotor and the pinion forces are absorbed by the bearings and the gear housing. The rotor forms a unit with the gear pinion shaft and, as a compact unit, can be easily installed in the stand during assembly.
  • Such a rotor mounted on the fly is advantageously designed as a solid rotor or as a plate rotor for reasons of vibration and stability.
  • FIG. 1 shows schematically the structure of a double-axis longitudinal drive designed according to the invention as a longitudinal section
  • Figures 2 to 4 each show a particular embodiment of the rotor of the electric traction motor in whole or in part in longitudinal section.
  • each drive axle 1 is connected in a manner not shown by means of an elastic coupling to the large wheel 3 of an angular gear 4, in which the pinion 5 of the electric drive motor 2 engages.
  • the housing 6 of the angular gear bes 4 is in turn mounted in a manner not shown on a hollow shaft surrounding the drive shaft-1.
  • the electric traction motor 2 which is designed as a double motor, has a common stator with two separate stator core assemblies 7 of the same length, in the slots of which a continuous stator winding 8 is inserted.
  • the electric traction motor 2 has two identical rotors 9 of the same length. Each rotor 9 is overhung on one side in the housing 6 of the angular gear 4, for which purpose the rotor shaft 10 is arranged in roller bearings 1-1.
  • the pinion 5 of the rotor 9 can be inserted with a special stub shaft 12 in the rotor shaft 10.
  • This design of the electric traction motor 2 as a double motor with a common stator winding 8 has the advantage that the two drive axles 1 can have slightly different speeds, without any constraining forces occurring between the two completely independent runners 9.
  • Fig. 4 shows the execution of the rotor 9 as a solid rotor, in which the rotor body 15 in one piece with the Rotor shaft 10 is formed.
  • the rotor body 15 is provided with a recess 16 on one side, in which the roller bearings 11 of the one-sided flying bearing of the rotor 9 are partially accommodated within the rotor body 15.
  • an extension of the housing 6 of the angular gear 4 also projects into the recess 16.
  • the rotor winding 17 is designed as a cage winding.
