Definitions

  • the invention relates to a drive unit for rail vehicles with an electric drive motor, with a gear and with a main shaft designed as a hollow shaft, which acts on a wheel set via a rubber joint coupling.
  • the main transmission shaft is connected by means of a clutch to a hollow clutch shaft which acts on the wheel set via a second clutch and serves as a brake disc carrier.
  • the configuration according to the invention now makes it possible to dispense with brake disks arranged directly on the wheel axles and instead to arrange them on the hollow clutch shaft concentrically surrounding the wheel axle. This reduces the unsprung masses.
  • the outer surface of the hollow coupling shaft is provided with a braking surface arranged on its circumference.
  • these braking surfaces can be acted upon azimuthally, that is to say in the circumferential direction, or axially by braking units provided for this purpose.
  • the main advantage of the configuration according to the invention is that the replacement of worn brake surfaces does not require the removal of the gearbox, but only the replacement of the hollow clutch shaft.
  • FIG. 1 shows a hollow coupling shaft 10, which is designed as a circular cylindrical body and has ring flanges 12, 14 on the end faces.
  • a hollow coupling shaft 10 which is designed as a circular cylindrical body and has ring flanges 12, 14 on the end faces.
  • circumferential radial formations 16, 18 are provided at a distance from one another and to the ring flanges 12, 14, which serve as braking surfaces.
  • These braking surfaces 16, 18, which are connected in one piece to the hollow coupling shaft 10, work together with brake units (not shown in more detail) which act on the braking surfaces 16, 18 radially, axially or azimuthally, depending on their design.
  • the braking units act axially such that the braking surfaces 16, 18 serve as brake disks.
  • the ring flanges 12, 14 located on the end faces are provided with uniformly arranged screw holes and serve to fasten a rubber joint coupling 20, which is only shown schematically.
  • one end of the hollow coupling shaft 10 is connected to a wheel 22 of a wheel set 24, which consists of a further wheel 23 and a wheel axle 25 connecting these two wheels 22, 23.
  • the wheel axle 25 is passed through the hollow coupling shaft and a hollow transmission shaft 26 of a transmission 28 which is also non-positively connected to the coupling 20.
  • An electric drive motor 32 is accommodated with the transmission in a common housing 30.
  • the drive motor 32 drives a pinion 36 fixed to its rotor shaft 34 to drive a gear wheel 38, which acts on the hollow clutch shaft 10 via the hollow gear shaft 26 and the rubber joint coupling 20, which in turn acts on the wheel 22 of the wheel 22 via the rubber joint coupling 20 Wheel set 24 drives.
  • the wheels 22, 23 of the wheel set 24 are releasably plugged onto the wheel axle 25, so that in the event of a repair or replacement of the hollow coupling shaft 10, only the wheel 22 located on this side of the wheel axle 25 must be removed in order to be able to remove the hollow coupling shaft 10 after loosening the rubber joint coupling 20.
