Definitions

  • the present invention relates to a fully sprung single wheel drive of a low-floor rail vehicle according to the preamble of claim 1.
  • the drive is regularly mounted on the outside of the drive wheel. But because a certain width may not be exceeded in rail vehicles, the available space for the drive is limited. As a result, the performance of the Drive is also limited, because there is no room for a larger electric motor and a correspondingly larger braking device. It should be noted that even in low-floor rail vehicles a maximum ground clearance is sought so that bumps, possibly existing snow accumulations or the like can be reliably run over.
  • From the EP 0 698 540 B1 is a drive for a low-floor rail vehicle is known in which an electromechanical drive via a drive shaft to an angle gear with a bevel gear acts, and wherein between the bevel gear and the wheel designed as a wedge-pack clutch cardan double clutch is provided. Between the electromechanical drive and the angle gear, a braking device is provided on the drive shaft. This braking device and the electric drive are arranged within a housing between the driven wheels. Thus, the low-floor rail vehicle has sufficient ground clearance for operation, the drive motor and the braking device can only have a small diameter.
  • the from the EP 0 698 540 B1 known drive with its limited drive power is used in inner-city operation on flat roads and well-developed railways with only low bumps and only little snow.
  • the present invention the object of the invention to provide a drive device of the type mentioned above, which allows a greater engine performance with high ground clearance, or at the same engine power has increased ground clearance.
  • a trained according to this technical teaching drive device has the advantage that the attachment of the brake device outside the drive train allows the use of a larger brake disc, because outside the housing of the transmission more space is available, which ultimately leads to a higher braking performance.
  • Another advantage is that a brake disc arranged outside the transmission / drive train is better ventilated, because there is a simpler air exchange than inside the transmission / drive train. This results in the same size of the brake disc to an improved braking performance or the same braking power to a smaller disc, resulting in increased ground clearance.
  • both the caliper and the brake disk are held on the drive train, in particular on the transmission.
  • This has the advantage that between the caliper and the brake disc no relative movement takes place with the result that the entire surface of the brake disc can be used.
  • This in turn allows for the same braking effect the use of a smaller brake disc and leads to a more compact design of the drive device, the width of the drive device is reduced and the ground clearance is increased.
  • the attachment of the brake disc to the transmission shaft by means of a spur gear and / or a central screw facilitates the assembly and disassembly of the brake disc, which contributes to a further reduction in maintenance and repair costs.
  • the transmission is designed in two stages, wherein between the first and the second stage, a transmission shaft is provided.
  • This transmission shaft is preferably designed as a bevel pinion shaft.
  • Figs. 1 to 3 show in a schematic way a part fully sprung single drive a low-floor rail vehicle with a schematically indicated chassis 10, which is held on a bogie 12.
  • a drive train 14 is held, which drives a running on a rail, not shown here drive wheel 16.
  • the drive train 14 itself in particular comprises an electromechanical drive 18, a drive shaft 20, a transmission 22, a clutch 24, a wheel adapter 26 and a brake device 28.
  • Fig. 3 is the electromechanical drive 18 only indicated, which drives the drive shaft 20 ,.
  • a steel diaphragm coupling 30 is provided between the electromechanical drive 18 and the drive shaft 20 in order to compensate for any relative movements between the electromechanical drive 18 and the transmission 22.
  • the drive shaft 20 is provided with a spur gear 32 which is in operative connection with a bevel pinion shaft 34.
  • the bevel pinion shaft 34 is designed as a bevel gear 35 and is in operative connection with a correspondingly formed, not shown here hollow shaft transmission.
  • This brake device 28 includes under a brake disc 36 and a brake caliper 38.
  • both the brake disc 36 and the brake caliper 38 are attached directly to the transmission 22, wherein the brake disc 36 is fixed via a central screw 40 at an opposite end of the bevel gear 35 of the bevel pinion shaft 34.
  • a spur gear 42 is provided between the brake disc 36 and the front end of the bevel pinion shaft 34 in order to allow a good power transmission from the brake disc 36 to the bevel pinion shaft 34. Via the central screw 42, the exposed brake disc 36 can be easily assembled and disassembled, which reduces maintenance costs.
  • both the brake disc 36, and the caliper 38 directly on the gear 22 a relative movement between the brake disc 36 and the brake caliper 38 is avoided, so that the entire surface of the brake disc 36 can be used for braking. This in turn allows a smaller design. Thus, both the width of the entire drive device is reduced and increased as well as their ground clearance.
