Definitions

  • the present invention relates to a Losradachse with individually mounted wheels for single or double axle chassis rail vehicles, in particular low-floor vehicles, with a U-shaped, the wheels with lateral Support legs outside encompassing Radtragrahmen, wherein each wheel on the inside of the associated support leg via a wheel bearing arranged inside the wheel a stub axle of the support leg is rotatably hinged, and wherein each wheel is torque-locked on its inside connected to a shaft extending through openings of the wheel and the support leg extends to the outside.
  • Such a loose wheel axle is described in WO 98/24674. It is concretely a driven axle, being on each chassis longitudinal outside of the chassis frame a drive is fastened. The drive is - due to a between the support frame and a Drive-carrying chassis frame provided primary suspension - via a gimbal double clutch with the wheel connected.
  • a first, drive-side coupling plane arranged on the outside of the drive and a second, output-side clutch plane is located directly on the Inside of the wheel.
  • the thus acting as a propeller shaft Wave runs consistently with appropriate length between the two coupling planes of the gimbal Double coupling.
  • This known Losradachse has the advantage that axis and drive can have a small width, for example, even narrow-gauge vehicles with at the same time small car body width without disturbing projection of the To allow landing gear.
  • Another advantage exists in that the bearing of the wheel within it is arranged, whereby a good load capacity and high Lifespan is reached.
  • this solution is then of Disadvantage if a maximum, only by the distance the wheels and necessary transverse suspension paths and clearances Limited aisle width (such as in low-floor wagons usual), as this is due to the inside the wheel arranged coupling plane is limited.
  • the disadvantage can also be hampered by the coupling plane Accessibility of wheel components, such. B. the Wheel bearing, for maintenance work.
  • should an adaptation to other z. B. even lower gauges virtually the entire design can be changed.
  • the present invention is based on the object, a Losradachse of the generic type to create with the a particularly good application variability, in particular in terms of adaptation to lower gauges achieved while maintaining the benefit of one optimal design of the wheel bearing by arranging the same inside the wheel. In addition, maintenance work be relieved.
  • the shaft as a brake shaft can be used by putting in the Coupling level is connected to a braking device.
  • the braking device is advantageous as a disc brake executed, with the brake shaft, a brake disc is connected, which supported with a support leg Brake caliper interacts.
  • the invention also includes maintenance and repair work fast and easy to carry out, because all Components are easily accessible. This is especially true for the wheel bearing, which is almost free from the frame inside is accessible, and advantageously without disassembly of the drive.
  • the drive itself can be simple and fast be separated from the intermediate shaft according to the invention, without causing the frame-mounted part dismantled would have to be (wheel with intermediate shaft).
  • One in case of one electrical drive required grounding contact arrangement is preferred on the outside, d. H. leading the way from the wheel End of the shaft according to the invention arranged integrated in this.
  • the ground contact arrangement can also be good through the hollow drive shaft through from the vehicle outside be achieved.
  • Fig. 1 is initially an example of an application of two erf indungsdorfen Losradachsen 1 in a driven Double axle landing gear illustrated.
  • a drive unit 2 negotiate, the from an electric motor 4 and flanged on both sides Bevel gearboxes 6 consists.
  • Each axis has a U-shaped Wheel frame 8 on, also under the term Portal axis is known.
  • wheels 10 stored individually, the wheel support frame 8, the wheels with lateral support legs 12 engages around the outside and each Wheel 10 on the inside of the associated support leg 12th is hinged.
  • Each drive unit 2 is at one suspension frame not shown suspended via a primary suspension on the respective wheel frame 8 is supported.
  • the wheel support frame 8 in particular in Area of the support legs 12 bearing surfaces 14 for primary spring elements on.
  • each wheel 10 is on its Inside torque-tight connected to a shaft 16, extending through openings of the wheel 10 and the Carrying leg 12 extends to the outside.
  • This shaft 16 ends According to the invention in a directly on the outside of the Carrying leg 12 formed coupling plane 18th
  • the shaft 16 is on its inside over a detachable connection element 30 rigidly connected to the wheel 10, so that the shaft rotates coaxially with the wheel.
  • the wheel 10 itself is about a wheel bearing 32 on a in the wheel 10th engaging axle stub 34 of the support leg 12 stored. This embodiment ensures optimal bearing stress and thereby a long shelf life of the bearings.
  • the Shaft 16 can - as shown - additionally via a pivot bearing 36 be stored in the support leg 12.
  • the shaft 16 forms a drive intermediate shaft 20, in the coupling plane 18 via a Clutch 22 with an actual drive shaft 24 of the Drive unit 2 is connected.
  • the drive shaft 24 is on its other, opposite side over one another clutch 26 with the gear 6 of the drive. 2 connected.
  • the Drive shaft 24 as an extension of the intermediate shaft essentially coaxial, preferably hollow cardan shaft and the two two-sided couplings 22 and 26 as gimbals Double clutch executed.
  • the drive shaft runs 24 through the gear 6 through, so that a Drive-side coupling plane 28 on the support frame of the 8th technological outside of the transmission 6 and the drive 2, while the output-side clutch plane 18 and the clutch 22 between the gear 6 and the support leg 12 of the support frame 8 are (see also Fig. 1).
  • Each coupling 22, 26 is made in a conventional manner star-shaped coupling pieces, with the interposition of elastic, wedge-like compensation elements interlock. This allows a gimbal balance of suspension movements of the order of at least approx. ⁇ 15 mm.
  • a ground contact arrangement 38 on the shaft 16 on the Side of the coupling plane 18 is arranged integrated. there it is a sliding contact arrangement to a electrically conductive connection between rotating and to ensure non-rotating parts.
  • the ground contact arrangement 38 is about a centric, through the hollow trained shaft 16 extending to the inside of the wheel Holding rod 40 and an adjoining, horizontal Torque support 42 fixed to the support frame. 8 supported. It can between the hollow shaft 16 and the Holding rod 40 at least one pivot bearing 44 may be arranged in particular in the interior, approximately in the plane of Rades 10 lying area.
  • the idler axle 1 also be used in a non-powered version. It then omitted the drive units 2 with the electric motors 4 and the gears 6 including the drive shafts 24. It can then each wave 16 advantageously as Brake shaft can be used by being in the coupling plane 18 is connected to a braking device. At this not shown alternative is then the braking device preferably designed as a disc brake, wherein with the Shaft 16 is connected to a brake disc, so that these rotates together with the wheel 10. The brake disc acts supported with a support leg 12 of the Radtragrahmens 8 Brake caliper together.
