Definitions

  • the invention relates to a device for the steering torque compensation of a steerable or self-steering wheel, in particular for rail vehicles, wherein the driven or braked wheel is subjected to a turning moment which is proportional to the effective wheel circumferential force and is determined by the wheel circumferential force and the steering roller radius from the outside.
  • the present invention is therefore based on the object of avoiding the disadvantages of the known device and of providing a device for steering torque compensation which is independent of the presence of a reduction gear and does not require more components than a comparable construction without steering torque compensation and itself can also be used on small bikes.
  • the solution to the problem is that the axis of rotation of a gear of a transmission is aligned with the pivot axis of the steering knuckle and this gear meshes with another gear which is connected directly or via an intermediate gear, for example a planetary gear, to the impeller and that the Rolling point of the tooth engagement of the two gear wheels acting tangential force F t with the operating pitch circle radius r b1 of the first-mentioned gear wheel results in a compensation torque which acts around the pivot axis and which is the steering torque formed by the wheel circumferential force F u and the steering roller radius r 1 in the same amount but in the opposite direction.
  • an intermediate gear for example a planetary gear
  • Two gears can advantageously also be arranged on a single shaft aligned with the swivel axis of the steering knuckle, one of which meshes with the gear of the output and the other gear meshes with the gear of the drive.
  • the gearwheel arranged in the steering knuckle is expediently mounted in the rotating part of the impeller in the presence of a downstream gearbox with at least one of several bearings.
  • the advantage of the device according to the invention is that its effect is independent of the presence of a reduction gear and that no more components are required than in a comparable construction without steering torque compensation.
  • the wheel 12 is supported with bearings 15 on the steering knuckle 11, which is pivotally pivoted about the pivot axis 10 on the axle bridge 16.
  • the axle bridge 16 is connected to the vehicle 17.
  • the drive shaft 18 mounted in the axle bridge 16 carries at its end a bevel gear 19 which meshes with the bevel gear 20 acting as an intermediate gear.
  • the gear 20, whose axis of rotation is aligned with the pivot axis 10, meshes with a further bevel gear 21, which is mounted with the bearings 13 and 14 in the pivotable steering knuckle 11.
  • the ring gear 23 of this epicyclic gear is rotatably connected to the steering knuckle 11 and the planet gears 24 are mounted on the planet gear carrier 25, which in turn is rotatably connected to the impeller 12.
  • FIG. 2 in which the same parts as in FIG. 1 are provided with the same reference numerals, shows an embodiment of the device according to the invention for steering torque compensation, in which the shaft of the gear wheel 21 is directly connected via a torsionally rigid, radially and axially flexible coupling 27 without an intermediate reduction gear is connected to the impeller 12.
  • two gear wheels 28 and 29 are mounted on a single shaft 30 that is aligned with the pivot axis 10 of the steering knuckle 11.
  • the gear 29 meshes with the gear 19 of the drive
  • the gear 28 meshes with the gear 21 of the output.
  • the embodiment according to FIG. 4 differs from the embodiment according to FIG. 1 only in that the shaft of the bevel gear 21 is mounted with one of the two bearings 31, 32 in the rotating part 25 of the impeller 12.
  • the embodiment according to FIG. 5 differs from the embodiment according to FIG. 1 only in that - due to the type of reduction gear used with the inner central wheel 22, the intermediate wheels 24 mounted in the steering knuckle 11 and the ring gear 23 connected to the wheel 12 - the directions of rotation of the gear 21 and the impeller 12 are in opposite directions.
  • the gearwheel 20, whose axis of rotation is aligned with the pivot axis 10, is therefore arranged here in such a way that the tooth engagement of the gearwheels 20 and 21 lies above the center line of the impeller 12, so that the compensation torque caused by the tangential force F t is caused by the wheel circumferential force F u Steering torque is directed in the opposite direction.
  • the amounts of steering and compensation torque are the same if equation (I) is fulfilled.
