Definitions

  • the invention relates to a drive unit for rail locomotives.
  • Drive unit for rail locomotives according to the preamble of the main claim.
  • 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 end facing 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 it 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.
  • a single wheel drive for vehicles in particular for railway vehicles, is known from DE-A 846 107, in which a drive motor is fixedly mounted on the sprung frame of the locomotive, the shaft of which is supported in two bearings arranged at the ends.
  • a pinion sitting on the shaft engages with a large gearwheel, which is connected to the drive wheel to be driven by means of a helical spring and is enclosed by a divided protective box.
  • the output-side support bearing of the motor shaft is held by a bearing plate which connects to a split protective box connected to the motor housing.
  • 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 a plane that runs parallel to the drive axis.
  • the two housing parts can be connected in a conventional manner by means of tie rods.
  • a drive unit 11 is shown, which is assembled from a drive motor 12 and a gear 14, which encloses a wheel axle 16 of a wheel set, not shown, in a common housing 38.
  • the drive unit 11 differs from conventional designs, inter alia, in that a conventional bearing plate for receiving the support bearing 26 is provided only on the side opposite the pinion, that is to say on the left in the drawings.
  • a housing section is provided, which is part of the housing part 38.1 on the drive motor side.

Claims (1)

  1. Ensemble propulsif pour des engins de traction ferroviaires comportant un moteur (12) électrique de propulsion qui présente un arbre de rotor (20) avec un rotor (22) placé sur celui-ci et un pignon (24) fixé à celui-ci qui est supporté dans des paliers (26, 28), ainsi qu'une transmission (14) qui est entraînée par le moteur (12) de propulsion et est reliée à un essieu à des fins d'entraînement de celui-ci, le rotor (22) et le pignon (24) étant placés entre les paliers (26, 28) qui sont disposés chacun à une extrémité de l'arbre de rotor (20), caractérisé par le fait que les moyens sont pourvus d'un carter (38) subdivisé en deux parties de carter (38.1, 38.2) parmi lesquelles la première partie de carter (38.1) reçoit le moteur de propulsion (12), l'arbre de rotor (20), le rotor (22), le pignon (24) ainsi que les paliers (26, 28) et se raccorde à la seconde partie de carter (38.2) qui contient la transmission (14), par le fait que le pignon (24) attaque directement la transmission (14), sans interposition d'un engrenage intermédiaire, et par le fait que plan de séparation des parties de carter (38.1, 38.2) s'étend parallèlement à l'arbre de rotor (20).
