Definitions

  • Such cars which heretofore have been used with the so-called 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.
  • the truck of the railway car is provided with steering wheel pairs for directing the vehicle and with support wheels for conveying the vehicle.
  • At each railway switch there are two guide rails, with outer guide flanges for supporting the steering wheels, which rails extend without interruption over the entire length of the railway switch.
  • one guide rail is provided for the straight direction and one guide rail is provided for the branch line.
  • the steering wheel pairs are arranged on a supporting device laterally displaceable with respect to the longitudinal axis (the axis of travel) between two limit positions in a manner whereby, in one of its limit positions, one steering wheel contacts the outer guide flange of the guide rail of the straight track line and, in the other limit position, the second steering wheel contacts the outer guide flange of the guide rail of the branch track line.
  • the track switch is passive (it has no moving parts) and may be used by several successive vehicles traveling in different directions.
  • the present invention provides the above-mentioned criteria with rather simple means, for bottomsupported as well as for suspended railway cars.
  • the word wheel includes all rolling bodies moving around an axis, such as rollers, etc.
  • a passive railway switch in which the direction is determined by at least one stationary guide rail having outer guide flanges for either the right or the left side of a railway car equipped with rimless guide wheels.
  • Each car has at least one supporting device adjustable between two limit positions, each corresponding to points of contact with two guide rails. Only one guide wheel at a time (of the supporting device) contacts one or the other of the two guide rails in each limit position.
  • the supporting device may be pivoted around a vertical axis by means of a switching device operating in the fashion of a toggle switch.
  • the supporting device is constantly maintained in one of its limit positions and may be moved to the other limit position by means of an internal (within the vehicle) switching device or by means of external (without the vehicle) steering rails disposed opposite the guide rails of the railway switch.
  • the switch mechanism may essentially consist of a bilateral positioning lever, preferably swiveling around the support axis of the supporting device between two limit positions, and a toggle lever, which is connected with one of the ends of the positioning lever.
  • the positioning lever is pivotably connected with the supporting device and is also axially displaceable against spring pressure.
  • connection chosen between toggle lever and positioning lever does not allow for changing the positioning lever with the toggle lever or the supporting device (i.e., it cannot be internally set) if the supporting device is brought into a limit position by a steering rail which limit position does not correspond to the limit position to be taken before the next railway switch and which had been pre-set by the set lever.
  • the supporting device achieves only a tilting of the toggle lever with axial displacement against spring pressure.
  • the supporting device is automatically returned into the pre-set proper limit position by this spring pressure as soon as it is released by the guide rail provided for the steering rail. This way it is possible to pass railway switches arranged in immediate succession (junctions, etc.) at high speed.
  • FIG. 1 is a plan view of a railway vehicle car provided with rimless supporting and guide wheels, with parts broken away for purposes of more clearly illustrating the invention
  • FIG. 2 is a cross-sectional view of the vehicle of FIG.
  • a railway truck shown in FIGS. 1 and 2 of a railway car not further illustrated or described consists essentially of a box-shaped body 1 having two wheel supports 2 for rimless wheels (e.g. rubber tires or the like).
  • Each wheel support 2 has two supporting wheels 3 mounted for rotation about a horizontal axis and two guide wheels 4 mounted for rotation about a vertical axis.
  • the wheels 3, 4 support and guide the railway car on horizontal support surfaces 5 and vertical inner guide flanges 6, respectively, of tracks 7 and 8 (FIGS. 4 and 5, respectively) which are either open at the top (FIG. 4) or at the bottom (FIG. 5) according to the arrangement of a railway car (not shown) to be connected to the truck.
  • the truck body 1 is suitable for bottom-supported vehicles, when the car rests on wheel supports 2, and is also suitable for suspended vehicles, when the car is attached to the body I.
  • FIGS. 1 and 2 there are two additional guide wheels 9 located above body 1, on a common, plate-like supporting device 10 (shown on FIG. 1 with parts broken away), which pivots about a vertical hollow bolt 11 (with collar) between two limit positions.
  • the device 10 is constantly maintained in one of its limit positions.
  • a switch mechanism provided in body 1, which mechanism consists of a positioning lever 13 pivoting around a bed bolt 12 (coaxial with the hollow bolt 11) between two limit positions, and a toggle lever 14 with coil spring 15.
  • Bolts 11 and 12 are firmly supported in body 1 and its cover plate 16, respectively as shown in FIG. 2.
  • bed bolt 12 passing through cover plate 16 tapers gradually and has threads 17 so that it rests at the cover and may be threaded to the hollow bolt 11, which is provided with a continuous female thread.
  • a spacing washer 19 is inserted between hollow bolt 11 and the cover 16.
  • Two bearing plates 20 are attached laterally to the body 1 to reinforce the supporting device 10; they may be made or'coated with a suitable plastic having good antifriction properties.
  • the connection with the set lever 13 is made by a guide bolt 21 which is pivoted in the lever 13, which lever has a radial bore 22.
  • the toggle lever 14 is axially displaceable in the bore 22 and is connected with supporting device 10 by a stop bolt 23 pivoted in the supporting device 10, which bolt 23 projects through an arcuate opening 24 in the cover 16.
  • a screw connection 26 secures the toggle lever 14 to the stop bolt 23, which itself is restrained in the axial direction by a safety washer 25.
  • the bed bolt 12 and the guide bolt 21 are provided with peg-shaped ends 27 which may be connected with the set lever 13 during manufacture.
  • the bolt 28 which is pivoted at the free end of the lever 13, which bolt 28 may serve to mount an adjusting device not shown here (e.g. an adjusting motor with lever gear or the like).
  • the set lever 13 consists of a pair of parallel lever plate elements 29, which are connected with each other through a spacer 30 by screw connections or the like.
  • a coil spring 15, acting between guide and stop bolts 21 and 23 respectively, ensures that the set lever 13, and the supporting device 10 are constantly maintained in one or the other of their two limit positions.
  • Stop lever 23 and the free end of the lever 13 rest on the same lateral surface 31 of the body 1.
  • the end of the set lever provided with guide bolt 21 rests on the opposite lateral surface.
  • the ends of the lever 13 determine its limit position. Of course, only one end, i.e. its free end, would have to be provided for.
  • both lateral surfaces 31 and the bearing plates 21 have horizontal slots 48 at the level of the toggle lever 14, in order to facilitate, in each limit position of the lever 13, the axial displacement of the toggle lever through lateral surfaces 31.
  • This switch mechanism is that supporting device 10 may be brought from the left limit position to the right limit position by means of its left guide wheel 9 without moving the lever 13 from its left limit position. Only the toggle lever 14 need be moved, in a fashion whereby it is axially displaced against the pressure of coil spring 15. When the left guide wheel 9 is released, the supporting device 10 is automatically returned to the left limit position set by the lever 13 by means of the coil spring 15. In the same manner, the supporting device 10 may be moved from the right position (not shown) to the left limit position through its right guide wheel 9 against the effect of the switch mechanism.
  • FIG. 4 shows, for example, a car in accordance with FIG. 1 with its supporting device 10 in the left limit position.
  • FIG. 3 In order to show this also in FIG. 3 (at the beginning of the railway switch), supporting girders 47 for guide rails 33 and 34 are shown with parts broken away. Even in case of a failure in the setting, e.g. failure of a switch not shown, which is coupled with the lever 13 (FIGS. 1 and 2), the switch mechanism ensures that the vehicle is guided along one of the guide rails 33 or 34. As already mentioned, supporting device 10 is always kept in one of its limit positions. Forces in the guide wheel 9 pass directly to the body through the supporting device 10 and the stop bolt 23; the rest of the switch mechanism is not involved in this action. If a railway switch (FIG.
  • the supporting device must be in a predetermined limit position (only one guide rail 33 or 34 is provided for each branch line). This is achieved, as shown in FIG. 3, by steering rails 37 having inner bearing surfaces 38 and following inner guide flange 39. At the end of the railway switch there is one such steering rail 37 arranged opposite each guide rail 33 and 34 so that, upon contact with one of the guide wheels 9 of the supporting device 10, the latter is brought into that limit position in which the second guide wheel 9 of the supporting device 10 contacts the outer guide flange 35 of the proper guide rail.
  • the supporting device 10 in case of wrong limit position, will be displaced by the steering rail 37 against the pressure of the coil spring (FIGS. 1 and 2) of the switch mechanism, and automatically will be returned to the limit position determined by the lever 13 after the railway switch has been traversed. Accordingly, while traversing a railway switch, the direction of the next railway switch to be passed in the merging direction may already be preset. This facilitates the construction of junctions, switch mechanisms in railway stations, and other short over-all lengths.
  • the supporting wheels 3 of one side of the truck of a suspended car cannot, by necessity, fulfill their function of support, i.e., the vehicle is only supported on the right or on the left side.
  • the right supporting wheels 3 of the truck are positioned over the opening 41 of the supporting beam 8 in the center of the railway switch.
  • the directive (left) guide wheel 9 then has dual functions, guiding as well as supporting.
  • supporting device 42 is equivalent to the one already mentioned (upper supporting device 2) and the two are rigidly connected by means of a shaft 46 going through the body.
  • the shaft 46 may be arranged axially and radially in the usual manner in body 1. It is advantageous to arrange the lever 13 described in FIGS. 1 and 2 pivoted on a bolt.
  • two supporting devices 10 and 42 with guide wheels 9 and 43 respectively is not limited to railway switches with small radius. Sway-resistance of suspended vehicles may be increased also in narrow curves of the tracks simply by adding guide rails (with outer guide flange). The latter is also true for bottom-supported vehicles, whereby their carriages would suitably have two upper supporting devices with guide wheels for reasons of load distribution. These may be arranged in such a fashion that in railway switches or curves one guide wheel (9) each can go over a front or back lower wheel (4) of wheel supports (2). Furthermore the guide wheels of the supporting device may be equipped with further guide wheels or possibly guide rollers, bolts, slides or similar, which can take over in case of rupture or failure of the corresponding guide wheel.
  • the cars may be driven by a linear motor, whereby such motor should have double translators arranged on both sides of the car body and stators attached to the lateral walls of tracks.
  • a linear motor In the center of a railway switch only one side of the track is driven, however, it is also possible to use driving motors for wheel propulsion. In the latter case, the supporting wheels also function as driving wheels.
  • a railway vehicle having rimless wheels, the direction of which vehicle is determined by contact with one of two stationary guide rails having outer guide flanges optionally provided for either the right or the left side of the vehicle, said vehicle including at least one supporting device mounting a pair of guide wheels adjustable between two limit positions, in each of said limit positions one of said guide wheels contacts one of the guide rails, means for mounting said supporting device for pivotal movement about a vertical axis, adjusting means comprising a plurality of levers operating in the nature of a toggle switch for pivoting said supporting deivce; at least one of said plurality of levers being displaceable relative to an adjacent one of said plurality of levers; biasing means maintaining said adjusting means in one of said two limit positions; said adjusting means being movable to said limit positions by means carried by said vehicle or by means of steering rails disposed opposite to said guide rails.
  • the adjusting means comprises a two-armed set lever pivoting about the axis of the supporting device between said two limit positions and a single-armed toggle lever connected with one of the ends of the set lever; said connection accommodating pivotal as well as axially displaceable movement against said biasing means.
  • a railway vehicle according to claim 1 including said guide rails and steering rails disposed in a forked switch characterized by the fact that the steering rails include a contact surface and inner guide flange arranged at the ends of the railway switch opposite each guide rail in a manner wherebycontact of one of said guide wheels of the supporting device is brought into the limit position where its second guide wheel rests on the outer guide flange of the respective guide rail.
  • a railway vehicle according to claim 2 character- 6.
