Definitions

  • the invention relates to a drive unit for rail vehicles with an electric drive motor with a rotor shaft mounted in support bearings, which carries a rotor (armature) and a pinion, and with a gear, which is acted upon by the drive motor and is connected to this for driving a wheel set.
  • a disadvantage of the known drives is the arrangement of the support bearings for the rotor shaft, wherein the support bearings take the rotor between them and the pinion is overhung on the protruding shaft stub pointing to the gearbox, so that the output-side support bearing of the rotor shaft also has a bending moment in addition to the drive torque the rotor shaft must accommodate.
  • This results in problems with regard to the design of the bearing since on the one hand this should not become too large because of the desired high engine speed, but on the other hand the desired high torque requires a large bearing diameter.
  • the advantage of the design according to the invention is based on the fact that the individual components, namely the drive unit, namely the drive motor and transmission, which are preassembled for installation in the rail locomotive and are now to be handled in one piece. It is provided according to the invention that the drive motor on the output side on which the pinion is arranged on the rotor shaft does not have a bearing plate, but that the support bearing on this side is rather an integral part of the common housing.
  • a joint of the common housing is placed in the plane in which the output-side bearing plate was originally arranged, so that the connection of the two housing parts can take place in a conventional manner by means of tie rods.
  • the parting line required for the individual assembly of the respective components is placed parallel to the rotor axis.
  • a drive unit 10 which is composed of a drive motor 12 and a gear 14, through which a wheel axle 16 is passed without contact, in a common housing 18.
  • the common housing 18 is divided along a parting line 19 into two parts which, on the one hand, accommodate the drive motor 12 and, on the other hand, the transmission 14.
  • the drive motor 12 has in its interior a rotor shaft 20 with a rotor 20 arranged thereon and a pinion 24 likewise fastened on the rotor shaft 20 and is supported in two support bearings 26, 28, which are each located at the shaft end of the rotor shaft 20. While the support bearing 26 in the rotor 22 enclosing Housing part 18.1 is inserted, the pinion-side support bearing 28 is inserted in the housing part 18.2 receiving the transmission.
  • the gear 14 is shown only roughly schematically with a main gear 30, which is arranged on a hollow shaft 32, which is supported in support bearings 34, 36 and at one end has a flange 38 for fastening a clutch, by means of which the connection to the here is not closer shown the wheel axle 16 having wheelset is produced.
  • a further gear wheel as an intermediate gear or a pair of gear wheels as a reduction stage can additionally be arranged in the gear housing.
  • FIG. 2 shows a drive unit 11 which corresponds almost identically to the arrangement according to FIG. 1 and which comprises a drive motor 12 and a gear 14 which has a contactlessly carried out wheel axle 16 encloses a wheel set, not shown, is assembled in a common housing 38. Accordingly, the same explanations apply to the specified reference numbers as have already been given for FIG. 1.
  • the arrangement according to FIG. 2 is a housing with a parallel to the wheel axis 16 or to the rotor axis 20 of the drive motor 12 or to the hollow shaft 32 of the transmission 14 extending joint 39 which divides the common housing 38 into a drive motor-side housing part 38.1 and a gear-side housing part 38.2.
  • the arrangement of the pinion-side support bearing 28, which takes the pinion 24 between it and the rotor 22 at the end of the rotor shaft 20 in the housing 38, is essential for both arrangements shown in FIGS. 1 and 2.
  • the drive unit 10 according to FIG. 1 and the drive unit 11 according to FIG. 2 differ from conventional designs, inter alia in that a conventional bearing plate is only provided on the side opposite the pinion, that is to say in the drawings on the left Support bearing 26 is provided.
  • a housing section is provided which, according to FIG. 1, is part of the housing part 18.2 on the transmission side and, according to FIG. 2, is part of the housing part 38.1 on the drive motor side.
