Definitions

  • the vertical surfaces of the directional rails contact the control wheels mounted on the railway vehicle for controlling che direction that the railway vehicle takes in traversing a branch
  • the guide wheels and control wheels are mounted on vertical axes for rotation in horizontal planes and are supported on a unique linkage which is adapted, under a vdynamic control influence applied from within the vehicle itself or from a static camming control influence applied by a steering rail disposed in the railway path prior to a junction (in which pairs of tracks are merging or diverging), to pivot the control wheels about the guide wheels to contact a selected one of the directional rails for the purpose of properly and safely directing the railway vehicle as it traverses the junction.
  • railway cars have been provided with rimless supporting or traction wheels disposed on horizontal axes and rimless guidance wheels disposed on vertical axes.
  • Such cars which heretofore have been used with the socalled girder road systems (bottom-supported or suspended railway vehicles), have the important advantage that pneumatic tires may be used as wheels.
  • a considerable advantage of such girder road cars is that they may be directionally switched across railway switches without the use of adjustable or moving track parts.
  • German patent publication DT-OS 2034106 a railway installation of this general type is disclosed in which directional rails are provided in the area of branch lines, however, the guide wheels for the railway vehicle disclosed in that publication are not equipped with their own drives. Accordingly, they are nonrotating as the railway vehicle traverses non-branching sections of the railway line, however, upon reaching an area of branching, they will be subjected to an abrupt and immediate commencement of rotation. This abrupt and immediate change in condition of the guide wheels from non-rotating to rapidly rotating is detected within the railway car as a jolt and is, of course, undesirable.
  • German publication DT-OS 2127088 another railway installation of this general type is disclosed in which there are continuous guide rails for the guide wheels. However, in that arrangement there is an absence of reliable guidance for the vehicle wheels in the area of branching lines.
  • one of the objectives of the present invention is to develop an improved and safe mechanism for guiding rimless railway vehicles at branching lines, while eliminating the undesirable effects of some of the earlier proposed switching arrangements.
  • this objective has been accomplished by the provision of a new and improved arrangement of railway apparatus in which a control wheel, located at each corner of the vehicle, is driven through a gear means, pulley means, belt means, or the like, by a guide wheel;
  • the driven control wheel is pivotable about the gear axis, in planetary" type fashion into contact with an appropriate directional rail at a branching area for properguidance of the railway vehicle therethrough.
  • the displacement of the control wheel into one of two positions (active and inactive) is effected by a special parallelgram-type control mechanism.
  • the control mechanism is arranged so that the control wheel pair on one or the other side of the vehicle are active, i.e., only one control wheel pair engages a directional wheel at a branch, in order to properly guide the railway car in its traverse of a branching area by contact with one or the other of the directional auxiliary rails located at a branching area.
  • the guide wheels on each side of therailway vehicle are rotated by contact with the vertical surfaces of the guide rails as the railway vehicle travels along the horizontal supporting surfaces of the main track.
  • This rotary motion is directly transmitted to the control wheels, by a mechanical coupling.
  • the control wheels are selectively displaced into engagement with the desired directional rail in a branching area by means of a steering device which may be controlled passively by the influence of a steering rail placed in the path of the railway vehicle ahead of the branching area, or by means of an appropriate electrolinear motor placed within the railway vehicle itself.
  • control mechanism for trans mitting rotation from the guide wheels tothe control wheels may comprise sprocket wheels mounted on the wheel axles and suitably interconnected by a roller chain or a gear train between the axles.
  • sprocket wheels mounted on the wheel axles and suitably interconnected by a roller chain or a gear train between the axles.
  • belts and pulleys in lieu of a gear train or in lieu of sprocket and roller chains.
  • pulleys advantageously enables an opposite direction of rotation to be established between the guide wheels and the control wheels by the simple expedient of criss-erossing the pulley'belt in known manner. Such opposite rotary motion is required when the directional rail is disposed inside the guide rail while the guide wheels and control wheels are located outside of the guide rail.
  • the control wheel or the driven element in all cases will be pivotable about the axis of the guide wheel or the driving element, i.e., the driven control wheel will have a generally planetary motion with respect to the driving guide wheel.
  • the guide wheels and the control wheels are preferably arranged in each of the four corners of a railway vehicle.
  • all of the control wheels are interconnected by means of a common control mechanism comprising a plurality of pivotably joined longitudinal links, cross links and levers.
  • the guide wheels are mounted on axles or shafts projecting from one end of one of the links of the mechanism while the control wheels are mounted at the opposite ends of those same links.
  • the entire control mechanism is bilateral and may be actuated into one of its two positions in which it steers a railway vehicle in one of two directions through a branch line by moving the control wheels into contact with one of the two directional rails present at each branch by means of an electrolinear motor mounted in a railway vehicle.
  • the secondary of the motor is an element in the mechanism.
  • Appropriate brackets for supporting the guide wheels at each of the corners of the vehicle also support the control mechanism interconnecting the control wheels with the guide wheels at each of the four corners of the vehicle.
  • the control mechanism in accordance with the principles of the invention, selectively pivots the control wheels in a planetary fashion about the axis of rotation of said guide wheels.
  • the linkage of the control mechanism is biased by a spring fixed at one end to the railway vehicle and at its opposite end to an element pivotable between two limit positions, which limit positions are established by the cooperation of mechanical stops disposed on the linkage and on the railway vehicle.
  • the spring is a coil spring arranged to operate the mechanism in the nature of a toggle switch. Accordingly, the switch-like mechanism of the invention does not have a dead center, and the linkage biased by the spring and pivoting the control wheels tends to function as a snap action toggle switch, so that as the linkage passes over center, it tends to be snapped into one or the other of its limit positions through the biasing effect of the spring.

Bottom supported and/or suspended vehicles 6 travel along pairs of main rails 1 in directions indicated by the arrows in FIGS. 1, 2, 4, 6, and 7. At railway junctions or switches, the direction of the railway vehicle as it traverses the junction is determined, in accordance with the principles of the present invention, by the proper setting or orientation of a bilateral switching or control mechanism 12 having two limit positions. The control mechanism interconnects vehicle guide wheels 8 and control wheels 9. The choice of the particular limit position of the control mechanism 12 may be effected by control means disposed within the vehicle, such as an electrolinear motor 15, or by control rails 5 disposed outside of the vehicle in the track path ahead of the junctions.

  • the longitudinal link 12a on the lefthand side of the vehicle is selectively displaceable by end functions in the nature of the secondary of an electrolinear motor 15 mounted on the vehicle truck.
  • the longitudinal links 12a carry stops 12c which cooperate with stops 6b on the vehicle truck 6 to establish opposite limit positions of the mechanism 12, i.e., the throw of the toggle switch mechanism.
