Definitions

  • This invention relates to railway vehicles having trucks which are equipped with wheelsets which are pivotally mounted to the truck.
  • the wheelsets are guided to a radial alignment during travel of the railway vehicle along circular curved track.
  • each wheelset is mounted in a steering yoke.
  • the yokes are interconnected.
  • these mechanisms make use of the yaw motion of the car body relative to the truck centre line to create the steering motions.
  • forces are created in a lateral direction on the outboard yoke and reacted through a reference link and lateral link to the truck side frame.
  • the stiffness which can be designed into these type of components making up the mechanical linkage, is usually such that steering accuracy is inadequate and stability against hunting oscillations is unsatisfactory.
  • the steering mechanism of this invention may be mounted on an existing truck having axles mounted in inter­connected yokes.
  • the mechanism is offset laterally from the centre line of the truck. It is advantageous to effect the mechanism as far as practical.
  • a steering mechanism for use on a railway vehicle having a car body mounted on at least two trucks. At least one of the trucks has inboard and outboard wheelsets, each of the wheelsets being mounted in a yoke. The inboard and outboard yokes are pivotally interconnected. Each of the wheelsets is affixed to the truck in such a manner as to be adapted for relative pivotal movement with respect to the truck about a general vertical axis.
  • the mechanism further includes a steering mechanism for guiding the wheelsets to a radial alignment when the vehicle is travelling on circular curved track.
  • the mechanism comprises a steering link connected to the car body and a steering lever which is pivotally connected to the steering link.
  • a linkage mechanism inter­connects the steering lever and the inboard and outboard yokes whereby relative longitudinal movement of the car body/steering link connection point with respect to the truck when moving from tangent track to circular track causes relative and opposite pivotal movement of the inboard and outboard yokes whereby the wheelsets assume a radial configuration when on curved track.
  • Figure 1 illustrates in side view, a truck or bogie, incorporating a preferred embodiment of the steering mechanism of this invention
  • Figures 2 and 3 show plan views of the truck or bogie.
  • the mechanism may be mounted on typical wheelset yokes and is offset laterally from the centre line of the truck as far as practical.
  • a bracket may be attached to the outboard yoke which bracket carries the lower pivot for a vertical steering lever which is thereby connected to it.
  • a steering rod is connected to the bracket by means of a pivotal connection and this steering rod is similarly attached to the inboard yoke through a bracket carrying a pivot connection.
  • the top of the steering lever is connected to a longitudinal steering link through a pivot connection and the other end of that link is connected to the car body.
  • the steering link As the car body swivels relative to the truck the steering link is moved fore and aft relative to points on the truck, thus pivoting the steering lever and forcing the yokes apart or together. Because the yokes are pinned together at the centre of the truck, the action of the steering mechanism is to cause the wheelset/yoke assemblies to rotate relative to one another into a steered alignment. Correct proportioning of the lever ratio ensures that true radial alignment is achieved on circular curves.
  • FIG. 1 illustrates a truck generally at 10 having a steering mechanism according to this invention installed thereon.
  • the truck comprises an outboard wheelset 12 and an inboard wheelset 14.
  • Each wheelset as will be understood by those familiar with railroad art, comprises an axle and a pair of flanged conical wheels fixed thereto such that the axle and wheels turn at the same radial speed.
  • Such conical wheelsets if permitted appropriate freedom will move to a radial configuration when travelling on curved tracks.
  • such single wheelsets are unstable and will continue to hunt when travelling on either tangent track or on curved track.
  • the wheelsets are mounted in yokes.
  • the outboard yoke is indicated at 16 and the inboard yoke at 18.
  • the truck frame is indicated generally at 20.
  • a bracket 30 is attached to outboard yoke 16.
  • the bracket 30 comprises a pivotal connection 32 at a convenient portion of the bracket.
  • a substantially vertical steering lever 34 is pivotally connected to bracket 30 at pivotal connection 32.
  • the steering lever 34 has a pivotal connect­ion 36 at its upper end.
  • a steering link 40 is pivotally connected to steering lever 34 at the pivotal connection 36.
  • the steering link 40 is attached to the car body, which is not illustrated, at connection 42.
  • the bracket 30, steering lever 34 and steering link 40 are all located laterally as remote as possible from the centre line of the vehicle.
  • the location of the steering mechanism is dictated by the configuration of the truck frame, the yokes and the configuration of bracket 30.
  • the advantage of having the mechanism remote as far as possible from the centre line is that larger motions are available for more accurate steering inputs.
  • the steering lever 34 has a pivotal connection 44 which is intermediate the pivotal connections 32 and 36.
  • a steering rod 46 is pivotally connected to the steering lever 34 at pivotal connection 44.
  • the steering rod 46 is pivot­ally connected to a bracket 48 at pivotal connection 50.
  • Bracket 48 is affixed to the inboard steering yoke 18.
  • the outboard steering yoke 16 and the inboard steering yoke 18 are pivotally connected to each other for relative pivotal movement.
  • connection 42 will move longitudinally as the truck pivots with respect to the car body.
  • the steering lever 34 will be caused to pivot about the pivotal connect­ion 32.
  • the steering rod 46 to be drawn to the left with respect to the pivotal connection 32.
  • the two wheels illustrated of wheelsets 12 and 14 respectively will be moved towards each other and thus accomplish a turn with the centre of curvature in front of the sheet.
  • movement in the other direction will cause the wheels illustrated in the drawing to move further apart accomplishing a turn in the direction with the radius of curvature behind the sheet.
