Definitions

  • the invention relates to a drive unit for the drive axles of rail vehicles with an electric traction motor, the torque of which is transmitted to the drive shaft via gearboxes and couplings and in which the housing of the traction motor stator, the bearing and the gearbox are connected to one another, wherein in Housing parts recesses are provided for the passage of the drive shaft.
  • a drive unit is known from DE-OS 23 25 787 and 23 64 594.
  • the structural design of the interconnected housings is in each case designed in accordance with the external dimensions in accordance with the drive parts contained in them.
  • the required boundary conditions, such as pinion shaft mounting and arrangement of the bogie cross member result in constrictions due to the limited space available, which have a disadvantageous effect on the stability of the drive unit.
  • the invention has for its object to increase the bending and torsional rigidity of a drive unit for rail vehicles.
  • a drive unit of the type described at the outset is designed in accordance with the invention in such a way that a hollow support is used as a common housing for all drive parts and has suitable mounting interfaces for inserting the drive parts.
  • a hollow beam the length of which corresponds to the length of the drive unit, has a high section modulus and, accordingly, a high degree of bending and torsional rigidity.
  • any suitable material of sufficient strength can be selected, e.g. B. aluminum alloys.
  • ferromagnetic material it is also advisable to use ferromagnetic material in such a way that the hollow support in the area of the drive motor forms all or part of its magnetic stator circuit. As a result, the function of the magnetic circuit in the traction motor area is also taken over by the hollow beam.
  • the hollow beam into the bogie, in which it is designed as a longitudinal center beam of the bogie and has side arms, which form the wheelset support arms. This is possible because of the given great bending and torsional rigidity of the hollow beam, so that the bogie is considerably simplified construction is achieved because the previously common bogie frame is no longer required because its function is taken over by the hollow beam.
  • FIG. 1 shows schematically, partially in section, a plan view of a drive unit designed according to the invention for the drive axles of rail vehicles.
  • FIG. 2 shows a side view, partly cut along line II-II in FIG. 1.
  • 3 to 5 show, also shown in principle, sections through the hollow beam in the area of the electric traction motor.
  • the electric traction motor 1 drives two drive axles 3 each via angular gears 2.
  • the electric traction motor 1 is perpendicular to the two drive axles 3 and its rotor shaft 4 is connected on both sides to the pinion shaft 7 carrying the pinion 6 via a centering coupling 5 which allows longitudinal displacements.
  • the pinion 6 is in engagement with the large wheel 8 of the angular gear 2, which is arranged on the hollow shaft 9 surrounding the drive shaft 3 with play.
  • the hollow shaft 9 is in turn connected to the drive shaft 3 via an elastic and centering rubber coupling 10.
  • all drive parts such as the electric traction motor 1, the pinion shaft 7 and their bearings, formed by roller bearings 11 and the angular gear 2, are arranged inside a hollow support 12.
  • This hollow beam 12 has the same outer dimensions over its entire length. It also contains recesses 13 for the passage the drive axles 3 and the hollow shaft 9 surrounding them and is closed off at the end faces by end walls 14.
  • the hollow carrier 12 continues to M o ntageschnittstellen 15 which obliquely, the recesses 13 extend for the cutting drive shaft 3.
  • the electric traction motor 1 which is completely designed with a housing, end shields and bearings for the rotor shaft 4, is first pushed into the interior of the hollow support 12, its position in the longitudinal direction being determined by a stop 16 inside the hollow support 12 .
  • a spacer ring 17 is then introduced on the other end face of the traction motor 1 and the support housing 18 for the roller bearings 11 of the pinion shaft 7 is inserted thereon.
  • the hollow shaft 9 is mounted in the hollow support 12 via roller bearings 19, so that the hollow support 12 forms the housing for the angular gear 2 there.
  • Corresponding seals are provided, by means of which the areas for the circulation of the lubricants required for the angular gear 2 or for the various bearings are limited within the hollow support 12.
  • This arrangement of all drive parts in the interior of the hollow support 12 creates a very rigid structure which is favorable in terms of running and operating properties.
  • this hollow beam 12 takes over the function of the longitudinal center beam of the bogie 20 and is therefore provided with side arms 21 which form the wheelset support arms of the bogie 20.
  • the hollow beam 12 can not only take on mechanically supporting functions, but also form its magnetic stator circuit 22 in whole or in part.
  • 3 shows an embodiment in which the hollow support 12 is used to guide a part of the magnetic flux of the stator circuit 22, so that despite the presence of a closed stator yoke 23, the main 24 and reversing poles 25 have a reduced height.
  • FIG. 4 shows an embodiment in which the main poles 24 and reversing poles 25 with their excitation windings 26 and 27 are inserted directly into the hollow support 12, so that this forms the magnetic stator circuit 22 alone.
