Definitions

  • the invention relates to a device for compensating undesirable steering torques on wheels of rail vehicles in particular, wherein a turning circumferential force which is proportional to the circumference of a driven or braked wheel and is determined by the circumferential wheel force and the steering roller radius is applied to the wheel in question from the outside.
  • the present invention is therefore based on the object of avoiding the disadvantages of the known devices.
  • the device should also be able to be used on small wheels.
  • the solution to the problem is that the wheel is mounted with one or more roller bearings on the steering knuckle and the reaction part of the planetary gear to be supported with roller bearings in the hollow hub of the wheel and between the reaction part of the gearbox and the axle bridge a known per se effective in both directions of rotation and articulated torque support is arranged.
  • the ring gear of the planetary gear is advantageously used as the reaction part to be supported, the ring gear being connected to the axle bridge via a lever serving as torque support or via two bevel gears which roll on one another or their segments.
  • the advantage of the invention lies above all in the fact that the device can be used with all wheel sizes, which was previously not possible. In addition, there is no need for complex leverage to switch the moments against each other.
  • the wheel is driven by a planetary gear integrated in the rail wheel.
  • the rail wheel 11 has a hollow hub 12 with which the wheel 11 with the interposition of two roller bearings 13 is arranged on the steering knuckle 14, which in turn is fastened with the roller bearings 15 about the axis bridge 26 on the chassis frame 17 so as to be pivotable about an approximately vertical axis 16.
  • the ring gear 19 of a planetary gear is also arranged with roller bearings 18, which meshes with the planet gears 20.
  • the planet gears 20 are supported with roller bearings 21 on the carrier 22 and mesh with the central wheel 23, which is connected via coupling elements and a universal joint shaft 24 to the drive shaft 25, which in turn is arranged in the axle bridge 26 in a manner known per se.
  • a torque support 27, 28, known per se and effective in two directions, in the form of a fork piece 27, which acts on a ball head 28, is arranged according to FIG.
  • the supporting torque of the ring gear 19 is transmitted to the axle bridge 26 in this way.
  • This torque support can also consist of two cams, which are arranged on the axle bridge 26, between which a cam attached to the ring gear 19 extends.
  • FIG. II Another possibility is shown in FIG. II, where a bevel gear 29 or a segment thereof is connected to the axle bridge 26 and another bevel gear 30 or a segment thereof is connected to the ring gear 19 to be supported.
  • a possible embodiment is characterized in that the pivot axis 16 of the steering knuckle 14 lies in a plane perpendicular to the wheel plane, which extends between the bearing group 18 of the fixed ring gear 19 of the planetary gear and the bearing group 13 of the wheel 11 on the steering knuckle 14.
  • the planet carrier 22 is connected to the wheel 11, whereas the ring gear 19 of the planetary gear via the rotation Torque support 27,28 is connected to the axle bridge 26 and therefore belongs to the non-rotating parts of the planetary gear.
  • a torque is transmitted to the central wheel 23 via the drive shaft 25, which torque can be a drive or a braking torque.
  • the support torque that occurs on the ring gear and is proportional to the drive or braking torque generates a circumferential force in the active surfaces of the torque support 27, 28 and 29.30, which generates a compensation torque with its lever arm to the pivot axis 16, which counteracts the steering torque formed from the wheel circumference force and the steering roller radius.
  • the planet gear carrier or the inner central wheel of the planetary gear can also be used as a part of the transmission to be supported.
