DE2349701A1 - Track-guided road-wheel vehicle railway junction points - has guidance device transferring between sides in diverging track - Google Patents

Abstract

The vehicles have horizontal drive-wheels for facing edges and guide-rollers for outside opposite edges, permitting drive on only one side. There is a guideway in the straight track on the side facing the diverging track, with an inner edge, comprising a stationary section near the froz zone, and a movable elastic tongue, which is deformable for production of the divergence. The diverging track has a stationary guideway at frog level with inner and counter edges, running partially parallel to the end of the elastic tongue, and forming together with this a double guideway for vehicles crossing into the diverging track or coming out of it, the guideway for the vehicle crossing from one side to the other.

German patent application P 23 14 119.7 employed by the applicant with the use of an elastic tongue that allows a single or double changeover between converging and parallel tracks allowed-

The present invention relates to the construction of a single switch for lanes of vehicles that are driven according to the above-mentioned S.S, S. system. Still based the invention on the prerequisites that the SoS.G. vehicles bring with them with regard to the fact that they are only on one side be guided.

The device according to the invention is characterized in that that in the straight track at the point of the switch at the Branch lane opposite side a guide with an inner edge and an opposite edge is provided, which consists of a stationary section (near the zone of the switch frog or frog) and consists of a movable, elastic tongue, the latter being fixed at the end remote from the switch frog and being deformable to produce the branch; and that in the branch lane at the height of the frog and this opposite a stationary guide with an inner edge and opposite edge is provided, which is partially parallel to the end of the the branch position occupying the elastic tongue runs and with this end a double guide for the changing lane Vehicle forms when the latter takes the lead from the one Side passes to the other side.

The guide ends with the edge and the opposite edge in the branch lane

practically at a distance from the straight lane that Its size is sufficient to allow the outer guide rollers of a vehicle traveling in a straight line to pass by.

Taking the advantages and requirements of those described above Soft with an elastic tongue are among others. above all the following should be mentioned:

a) Small size}

b) Extremely simple equipment and mode of operation and thus low construction and operating costs j

c) The possibility of a bank at the junction in the curve.

The simple mode of operation ensures a high level of safety, although this switch is not used by rail vehicles is driven on.

Further advantages and features of the invention emerge from the following description of a preferred embodiment in conjunction with the accompanying drawings. The drawing shows a plan view of a device according to the invention,

Corresponding are opposite sides or edges a straight track is provided, with which horizontal wheels 3 of the guide carriage of a vehicle cooperate. The vehicle owns road wheels and is in the track shown guided. Furthermore, sides or edges 5 are a branch track intended. The switch according to the invention is used to create a branch connection between the latter and the straight lane

place. Use the guiding devices of these lanes
In addition to the edges 1 and 5, there are also external mating edges that work together with external guide rollers.
The latter form part of that guide or drive unit which also contains the horizontal wheels 3. The guide rollers 7 are arranged in such a way that they cooperate offset in their height with respect to the wheels 3 with the outer opposing edges, the latter being provided in those sections in which the vehicle is not guided on both sides, but only on a single side. These
Guide or drive arrangement is under the designation
SS ₀ G. system known and developed by the applicant. The guide rollers 7 lie outside the wheels 3 and are preferably arranged opposite them. The distance between the wheels corresponds to the track width between the edges 1, which is in the
Drawing is provided with the reference symbol S.

Between the edges 1 and 5, a point or a so-called switch frog 9 is formed at the point of the switch, which
has an angle, v. The size of this angle changes with the curve radius of branch lane 5.

The edges 1 are interrupted at the point of the switch, the drive units of the vehicles being designed as follows. Essentially at the point of the switch frog 9 and on the side opposite the branch lane, that is, on the outside, a guide arrangement 11 with an edge and an opposing edge is provided. This guide arrangement 11 is aligned with the outer edge 1A of the track 1. It ends at the free end of an elastic

Tongue 13, which also corresponds to the outer edge 1A »This elastic tongue 13 is defined in the zone 13A and forms the continuation of the outer edge'IA of track 1. The tongue can assume a rest position 13X in which it is aligned with the guide arrangement 11. Furthermore, it can have an elastic Assume the deflected position, which is shown in the drawing in solid lines. She then follows the direction the branch lane. To deform the elastic tongue 13, a device 15 can be provided, which in the direction of the Arrow F acts essentially perpendicularly on the elastic tongue, namely at a short distance from the free end of the Tongue. When the tongue 13 is deflected, it assumes a parabolic shape, except for the portion of the free end, which remains straight and represents a tangent to the curve formed by the tongue. Also the fastening section of the The tongue in the area of the edge 1A forms a tangent to this curve. The elastic tongue 13 provides a guide edge and a mating edge for the horizontal wheels 3 and for the Guide rollers 7 for driving on only one side.

Along the outer edge 5A. the branch lane 5 is a stationary one Guide arrangement 17 provided with edge and opposite edge. the Guide arrangement 17 extends from the zone of the switch frog 9 against the straight track formed by the edges 1.

The guide arrangement 17 ends at 17A at such a distance of the straight track that a free passage for the guide rollers 7 of those vehicles is guaranteed, which

509815/0 22 5

are guided by their guide means along the rectilinear track. The movable end of the elastic tongue 13 is, if the latter assumes its elastically deformed deflected position, moved away from the end 11A of the guide arrangement 11 by such a distance that the guide rollers 7 of a drive unit, which is moved along and guided along the elastic tongue 13, be allowed through. The deformation of the elastic tongue forms an angle S between the guide assembly 11 and the tangent to the deflected end of the tongue 13 "This angle is smaller than the angle vL of WeichenherzstückSo the movement of the elastic tongue 13 that is, the angle ß ₉ is proportionally smaller based on the angle J. , if the latter increases, since the difference between the two angles increases when the angle X is taken .

A vehicle arriving in the direction of arrow F will only be guided by the two edges 1 and then arrives at the location of the switch frog to a right-hand guide, namely using the guide arrangement 11. It then happens' the elastic tongue 13, which is locked in its rest position 13X, and finally comes back to a two-sided guide through the straight edges 1, about at the Location of the attachment zone 13A. The dash-dotted line gives approximately the outer trajectory of the wheels 3 of a vehicle again, which moves in the manner described above. A vehicle traveling in the opposite direction of arrow F is driven in a corresponding manner.

heart piece 9 with a left-hand guide using the guide arrangement 17 and the wheels 3 and the guide rollers 7. Before reaching the end 17A of the guide arrangement begins the guide unit of such a vehicle at the same time with a right-hand guide on the tongue 13, the elastically deformed and in the unbroken line in the drawing Lines reproduced position is set. After passing the overlapping zone or the zone with both sides Guide (formed by the end 17A of the guide assembly and from the substantially rectilinear end of the Tongue 13) the vehicle begins with right-hand guidance, based on the direction of travel indicated by the arrow F ^, Then it occurs with the edges 1A next to the Attachment zone 13A in contact. One in the opposite direction of arrow F. moving vehicle will be in a corresponding manner guided. The dash-dotted line 21 denotes the path of movement of the outer edges of the wheels 3 of a one driving into the branch lane 5 or coming out of this lane Vehicle.

The profile of the turn-off lane, specifically that Profile of the guide arrangement 17, an increasing, possess parabolic curvature.

There is the possibility of the branch lane opposite the Edge 1A a transverse, increasing slope between the attachment zone 13A and the zone of the switch frog, i.e. H."

the zone of the guide arrangement 17 and the edge 5A. This enables the vehicle to travel smoothly and smoothly on the branch lane even when the Radius of curvature between the attachment zone 13A and the Zone of the guide arrangement 17 and the adjacent edge 5A decreases considerably.

In fact, and as is well known, one of the disadvantages of common road switches in that the curved branch-off lane is in the same plane as the straight line Track so that any transverse elevation of the The curve is completely omitted. As a result, the driving speed on the branch lane is reduced even further.

This deficiency can be counteracted in part by reducing the angle pj of the Wexchenherzstückes, if possible. This leads to a lengthening of the switch and to an increase in the radius of curvature of the branching section. However, for reasons of space it is not always possible and often even impossible to reduce the angle ^. It is then advantageous to give the branching section in the curve a camber in the transverse direction. This means that it is advantageous to place the switch in the curve.

This transverse elevation is based on a slight elevation (h) in section 1A-1B.

To simplify the description, it is assumed that the Curve section 1B-1C-5A is overall at the same level. This then results in the section of the switch frog D-1C an exaggeration H that is greater than the value h.

At this point you have to take into account that the sides of the Switch zone in the present case all independently of one another and that everyone is therefore able to create a Driving vehicle. In particular, the side 1B-1C-5A is independent of the side 13A-11 and independent of the side 13A-13Y, which forms the elastic tongues.

The only element that establishes the common connection is that the movement path of the vehicle wheels (indicated by the dash-dotted line 19 of the drawing) between 1B and D must increase by the value H, which does not cause any difficulties leads, while the trajectory in curve 1A-D must increase by the value (H-h). So it runs straight Lane 13A-1E inclines with respect to lane IB-D and also rises by the value (H-h). The inclination can disappear if points 1A and 1B are at the same level »because in this case the edges 13A-1E also increase by the value h, provided that points D and IE are at the same height.

It should be noted that the inclined line is 1A-1E on the line 1B-D depends on the values h and H. These are larger or smaller according to the setting of the pneumatic vehicle suspension, which gives the possibility of larger ones

or to set smaller differences in altitude. The longer the section 1B-D is, the easier it becomes to make a sizable Set cant (H-h).

So it turns out that the track is outside of the sections (1C-D), (1A-1B) and (1E-D) has the ability to progressively to take the optimal level-height course.

It should be noted that what is shown in the drawing Embodiment is only intended to show a practical implementation for the invention and that in Within the scope of the invention, modifications in terms of shape and arrangement given are.
