Further, since, in such branching device, the movable guide plates are constructed in the form of a straight line, the device has a problem that it fails to provide a smoothness when the vehicle passes through it.
- the object of the present invention is to provide a switching device for vehicle which eliminates the above-mentioned problems inherent in the prior art, which is simple in construction, which is easy to maintain, and which makes it possible for the vehicle to have wider space for providing a current collector or power rails and to make a smooth switching movement.
- the present invention has been accomplished by discovering that the problems considered important in the prior art, i.e., the above-mentioned problems that when single guide wheel is guided between two vertical walls of a wheel way, it is brought alternatingly into contact with either of the two vertical walls of the wheel way and is thereby caused repeatedly to make its normal and back rotations and thus frictionally worn very much, are practically not serious problems, that is to say, by discovering that such problems are practically not fatal problems for the reasons that the guide wheel in the switching section is likely to be guided in contact with only one side wall of the wheel way; that, on the other hand, the length of the switching section is remarkably short as compared with the entire length of the track; etc.

- The present invention relates to a switching device for vehicle, applied to a vehicle guiding system wherein a vehicle is guided by its guide wheels allowed to rotate within a horizontal plane.
- Many of those vehicles arranged to travel on an exclusive track through their rubber made tires are guided leftwards or rightwards by means of their wheels which are provided horizontally.
- Fig. 1 shows a prior art vehicle of such type and a switching device for vehicle involved. The vehicle A has a
travel wheel 3 of rubber tire and travels on anexclusive track 10. In other track section than that in which the switching device is installed, the vehicle A is guided by travel of its guide wheels along their corresponding rail and by detecting the position of the vehicle A relative to the rail, or the variation thereof and by steering thetravel wheel 3 accordingly. - The track includes a general section and a switching section when it is roughly classified. Usually, in the general section, main rails 11L and 11R are provided on both sides of the track and, in the switching section, an
auxiliary rail 12L andmovable guide plate 13L, and anauxiliary rail 12R andmovable guide plate 13R are added to the main rails 11L and 11R, respectively, as shown in Fig. 1. - In Fig. 2, a sectional view of the vehicle A is shown. As seen, the guide wheels which are provided horizontally include two types of guide wheels, one of which is main wheels 1 and the other of which is switching wheels 2. In the vehicle shown in Figs. 2a and 2b, the main wheels 1 are guided by the main rails 11L, 11R while the switching wheels 2 are guided by the
auxiliary rails guide plates - When the vehicle travels on the track of general section, the main wheels 1 respectively provided on the right and left sides of the vehicle are guided by the right and left main rails 11L, 11R, respectively. In the switching section of track, the switching wheels of one side are guided by and along a corresponding one of the wheel ways H respectively provided between the main rails and auxiliary rails on both sides of the track. For selecting the course of the vehicle, in a switching section the
movable guide plates switching device 14 whereby the wheel way H is selectively formed on either one side of thetrack 10. - The construction of such switching device for vehicle is known as dissolved in Japanese Utility Model Laid-Open No. 126303/80, Japanese Patent Publication No. 264/81, Japanese Utility Model Laid-Open No. 123001/80, or Japanese Patent Laid-Open No. 39807/76.
- In the prior art, however, the above-mentioned two types of guide wheels, i.e., main wheels and branching wheels are always used as the horizontal guide wheels. Further, such arrangement of prior art intends, as understandable from Figs. 2a and 2b, that, during the travel of the vehicle in the switching section, any of main wheel and switching wheel is allowed to contact with the main rail or auxiliary rail only on one side of the wheel, whereby to prevent the wheels from making their reverse rotation and being much frictionally worn. Providing the switching wheels in the same number as that of the main wheels, however, means that a valuable space is employed only for the purpose of performing the switching operation which occupies a very small percentage in the entire travelling operation of the vehicle. This is not preferable from the viewpoint of spatial efficiency. On the other hand, while the branching wheels perform a very important function of selecting the course of the vehicle, a failure involved in such branching wheel will result in a great accident. For this reason, a large amount of labour is spent for their maintenance and inspection similarly as in the case of for maintenance and inspection of the main wheels.
- In the meantime, since the guide wheel 1 and the corresponding switching wheel 2 are vertically arranged in upper and lower stages, the respective positions of the main rails 11L and 11R become correspondingly high and the space required for installing the rails becomes correspondingly large. Accordingly, a space for providing
power rails 15 provided on the side of the track and used to supply a power, as well as a space for providing acurrent collector 4 on the side of the vehicle becomes necessarily small. - Further, in the switching device of the above-mentioned system, the movable guide plates are pivotally supported by the pins 13' as shown in Fig. 1, it becomes necessary to make dimentional adjustment of the device, make replacement of the worn pins or bushes, effect the supply of oil to the relevant parts, etc. Namely, there remains some problem of maintenance unsettled. Further, since, in such branching device, the movable guide plates are constructed in the form of a straight line, the device has a problem that it fails to provide a smoothness when the vehicle passes through it.
- In view of the above, the object of the present invention is to provide a switching device for vehicle which eliminates the above-mentioned problems inherent in the prior art, which is simple in construction, which is easy to maintain, and which makes it possible for the vehicle to have wider space for providing a current collector or power rails and to make a smooth switching movement. The present invention has been accomplished by discovering that the problems considered important in the prior art, i.e., the above-mentioned problems that when single guide wheel is guided between two vertical walls of a wheel way, it is brought alternatingly into contact with either of the two vertical walls of the wheel way and is thereby caused repeatedly to make its normal and back rotations and thus frictionally worn very much, are practically not serious problems, that is to say, by discovering that such problems are practically not fatal problems for the reasons that the guide wheel in the switching section is likely to be guided in contact with only one side wall of the wheel way; that, on the other hand, the length of the switching section is remarkably short as compared with the entire length of the track; etc. Further, the present invention has been materialized with conception that the auxiliary rails and movable guide plates need not be high in stiffness since they are solely intended to guide only the guide wheels for obtaining a steering signal unlike those intended to guide the travelling wheels as in case of a railway.
- The above object of the present invention is attained by arranging the main rails and the corresponding auxiliary rails such that the vertical guiding surface of the former rail and that of the latter rail are opposed to each other with the same height. Further, the above another object of the present invention is attained by preparing the movable rail in a manner that it is integrally and bendably connected at one end to a auxiliary rail or main rail by reducing lateral stiffness of connecting portion and the other free end of the movable rail is made flexible.
- An embodiment of the present invention will now be described with reference to the accompanying drawings.
- In Fig. 4, over the substantially entire length of a switching section S having main rails 11L and 11R provided thereon,
auxiliary rails auxiliary rail 12L adjacent to an entrance of the switching section S forms aswingable rail 12M, thus defining a switching section M..Assume now that a vehicle A mounted, at its right and left sides, with guide wheels 1 arranged to rotate within a horizontal plane, comes on from a direction indicated by an arrow. Then, the vehicle, in accordance with the position of the swingable rail, advances rightwards by having its right guide wheels guided along a right wheel road Hr, or alternatively advances leftwards by having its left guide wheels guided along a left wheel way H£. As seen in Fig. 5, a vertical guiding surface of the main rail 11 and a vertical guiding surface of theauxiliary rail movable rail 12M are same in height and made to oppose each other with one guide wheel 1 interposed or guided therebetween. - In this embodiment, the
swingable rail 12M is constructed in such a manner as to continue from the fixed or stationaryauxiliary rail 12L, and abending portion 20 is made small in the lateral stiffness and thereby made flexible or bendable. Afree end portion 12F (indicated by a-one-dot chain line in Fig. 4) of theswingable rail 12M is also made small or less in the lateral stiffness, whereby, when it is contacted with the main rail, it flexes to form a smooth guiding surface. - In the meanwhile, the
auxiliary rail 12R of the branching side is also fixedly provided over the substantially entire switching section S. In this case, however, anend 12F' of theauxiliary rail 12R is retreated from a point corresponding to said free end portion F, to such an extent that, when the vehicle advances straight along therails 11L and 12L, no hindrance arises in passing of its right-side guide wheel 1. Theends 12E', 12F' of theauxiliary rail 12R, as well as therespective ends auxiliary rail 12L andswingable rail 12M, should be extended up to the positions at which the vehicle can reliably be guided by only main rail 11L and opposing main rail 11R. Further, the swingable rail-12M may of course be provided on theauxiliary rail 12R. - Figs. 6, 7a, 7b and 7c each show a detailed structure of an embodiment of the
swingable rail 12M shown in Figs. 4 and 5. Cross-sectional shapes of main. rail 11L andswingable rail 12M are, however, not limited to those shown in these figures. In Fig. 7C, the cross section of the free end portion is shown, which joins themovable rail 12M to the corresponding main rail 11L. As seen, horizontal and vertical webs of the T-shapedmovable rail 12M have their respective parts omitted or cut away, whereby themovable rail 12M is reduced in the lateral stiffness. Thus, theswingable rail 12M is made flexible and thereby made capable of being pressed contact with the main rail so that it may have a smooth guiding surface. The reduced thickness of vertical webs is helpful for a smooth guiding..Further, the cross section (b-b) of an intermediate portion of theswingable rain 12M indicates that no particular fabrication is required in this intermediate portion. In the cross section (a-a) of a bending portion of theswingable rail 12M, a horizontal web thereof has its parts omitted or cut away, whereby reducing the lateral stiffness. Further, as shown in Fig. 6, theswingable rail 12M may be provided with an embossedportion 21 for reliably introducing the guide wheel 1 residing on the opposite side from theswingable rail 12M into the corresponding wheel road Hr. The necessity of the embossedportion 21 depends on the positional relation between the bendingportion 20 and theend portion 12F' of the opposingauxiliary rail 12R, this is, the embossedportion 21 is not required in case that theend portion 12F' is located more toward the entrance of switching section than the bendingportion 20, or in case that swingable rails are provided on both sides of the track as will be mentioned later. - In Fig. 8, there is shown another embodiment of the
swingable rail 12M, in which the swingable rail is provided on each of theauxiliary rails portions - When the movable rail 12ML is pressed against the main rail 11L by the switch-over force of the
switching device 14, a portion of the swingable rail 12ML which resides in the vicinity of the free end 12FL thereof is caused to flex or bend due to its elasticity and is thereby pressed contact with the main rail 11L. Thus, a desired smooth guiding surface is obtained. Since the swingable rail 12MR of opposite side is made curvilinear, it is possible to cause both the swingable rails 12ML and 12MR to suitably share a load applied from the guide wheels if, for example,stoppers 23 are located at the center side of the track. Where, on the contrary, the vehicle takes the straight course, pressing the swingable rail 12MR against the corresponding main rail llR by the switching device would cause the swingable rail 12MR to flex to pressed contact with the main rail 11R. Thus, a substantially linear rail form or guiding surface is obtained. At this time, the movable rail 12ML of opposite side is restored to its original linear form, whereby the guide wheels are guided without hindrance. Constructing theswingable rail 12ML or 12MR in a manner that it has thebendable portion - Fig. 9 shows still another embodiment of the present invention. This embodiment refers to a switching device wherein the
auxiliary rails passage 22 for passing the swingable rails. - In any case of the foregoing descriptions, reference was made to the case where the height of the main rails is made same as the height of the auxiliary rails. With such construction, it is possible, as stated before, to omit the provision of the branching wheel 2 to the vehicle, and also to make the constructing of the
current collector 4 and the power rails 15 on the I track easy. - However, it is also possible to improve.the switching device already in service for passing a vehicle equipped with the prior art guiding system in a manner simply to make the movable rail at both ends laterally bendable, resulting in a simple machanism of the switching section and in a smooth passing of the vehicle through the switching section.
- Fig. 10 shows the difference between the vehic guiding system according to the present invention shown at right side and that according to the prior art shown in left side. As seen in Fig. 10, the heightwise space necessary for the guide wheel section of the present invention becomes smaller as compared with that of the prior art, and the height of the main rail is reduced correspondingly to that of the guide wheels, by amount of Ah = hl - h2. As a result, the arm of moment applied to the main rail from the guide wheel become shorter, and the space for accommodating the power rails 15 become wider.
- The present invention has the following effects.
- (1) The vehicle has only main guide wheels, but no switching wheels. This makes it possible to omit the expenditures and labour involved in the manufacture and maintenance of such switching wheels.
- (2) The heights of guide wheels as well as of main rails are reduced. As a result, installation of the
current collector 4 in the vehicle and of the power rails 15 in the track become easier due to their wider spaces, and thesupport column 24 for the main rail may be light-structured due to the reduced arm length of moment applied thereon. - (3) Since, according to the invention, the supporting of the branching device is effected by elastic flexure or deformation instead of by hinge joints with pins, it is possible to eliminate the complexity in manufacture and maintenance which might be caused by the hinge joints with pins. And,
- (4) Since, according to the present invention, it is possible, by utilizing the elastic deformation of the swingable rail itself, to provide a smooth guiding surface at the switching portion of the track, the comfortable ride of passengers being obtained.
