Definitions

  • the present invention relates to a gear arrangement for driving a wheel set shaft of a rail vehicle according to the closer defined in the preamble of claim 1.
  • axle drive for a rail-bound railcar.
  • the axle drive as a gear arrangement between the left and right drive wheels of a wheelset below ground, so installed below the vehicle floor.
  • the transmission is the drive side connected to a drive motor and the output side with the axle of the bogie of the rail vehicle.
  • the drive shaft is arranged parallel to the direction of travel, wherein the output or the wheelset is arranged transversely to the direction of travel. Consequently, a bevel drive between the drive shaft and the axle is required.
  • a predetermined ratio is necessary so that in addition to the bevel gear and a spur gear is provided.
  • the drive shaft is therefore connected via a spur gear with a bevel pinion, which is in engagement with a ring gear, which is coupled to the axle.
  • a drive unit with a drive machine for driving at least one wheel in which the drive machine is arranged offset in the axial direction to the wheel axle. It meshes with the output shaft of the drive machine rotatably connected pinion with the internal teeth of a ring gear.
  • the ring gear is in turn rotatably coupled to the wheel axle.
  • the present invention is based on the object to propose a gear arrangement of the type described above, which on the one hand provides the predetermined gear ratio and on the other hand reduces the Hypoidversatz to a minimum.
  • the transmission arrangement comprises at least one spur gear drive connected to a drive shaft and at least one angle drive connected to the wheelset shaft, the road wheel drive comprising a spur gear driven by the drive shaft or the drive motor with external teeth or the like and a ring gear driving the angle drive with internal gearing or the like.
  • the internal gear is realized in the spur gear in a structurally simple manner that the smaller diameter than the ring gear having spur gear is at least partially disposed within the ring gear, so that the external teeth of the spur gear meshes with the internal teeth of the ring gear.
  • the present invention will be further explained with reference to the drawing.
  • the sole figure of the invention shows an example of a possible embodiment of a gear arrangement according to the invention for driving a wheel set shaft 1 of a rail vehicle, such as a railcar or the like.
  • the gear arrangement comprises a gear housing 2, in which at least in sections a connectable to a drive motor not shown drive shaft 3 is mounted, which is coupled via a spur gear and an angle drive with the wheelset 1. This results between the drive or the drive shaft 3 and the output or the wheelset 1, a vertical distance C.
  • the spur gear comprises a connected to the drive shaft 3 spur gear 4 with an external toothing 5 and a coupled with the angular drive ring gear 6 with internal teeth 7.
  • the spur gear 4 is dimensioned such that it is at least partially disposed within the ring gear 6, so that the external toothing 5 is in engagement with the internal toothing 7 of the ring gear 6.
  • the ring gear 6 has an axial length which is dimensioned such that the ring gear 6 is connected to a bevel pinion 9 of the hypoid drive or hypoid stage formed angle drive.
  • the two bearing points 10 of the ring gear 6 also serve to support the bevel pinion 9.
  • the bevel pinion 9 is in engagement with a ring gear 11 of the hypoid drive, wherein the ring gear 11 is connected to the wheelset shaft 1.
  • connection between the ring gear 6 and the bevel pinion 9 can, as shown in the figure, be realized via a sleeve member 12 by the shaft of the bevel pinion 9 is disposed inside the sleeve member 12, wherein the sleeve member 12 in turn in the inner diameter or in Inside the ring gear 6 is added.
  • This connection can be realized for example by a press fit or by pressing.
  • the ring gear 6 and the bevel pinion 9 are integrally formed.
