Description

  The present invention relates to a guide rail and a track-type traffic system including the guide rail. More specifically, a guide rail that guides a track-type vehicle including a pair of guide portions that are arranged in the vehicle width direction and that are spaced apart from each other along a travel route, and a track-type traffic system that includes the guide rail About.

  In recent years, as a new means of transportation other than buses and railroads, a new transportation system, which is a kind of track transportation system, has attracted attention. As such a new transportation system (Automated People Mover, Automated Transit Systems), there is known a system that travels a vehicle having traveling wheels made of rubber tires on a traveling road. In the new traffic system, a guide rail is provided to define the traveling direction of the vehicle.

  As a guide rail system for this type of vehicle, there are a central guide rail system and a side guide rail system. The central guide rail system is a system for guiding a vehicle along a travel route by a central guide rail disposed in the center of the travel route. The vehicle is provided with a pair of guide wheels that sandwich the central guide rail. The vehicle travels in a direction along the central guide rail when one of the pair of guide wheels comes into contact with the central guide rail and the guide wheels receive a force in the width direction of the travel path from the central guide rail. Will do. The side guide rail system is a system for guiding a vehicle along a travel route by a pair of side guide rails arranged on both sides of the travel path. The vehicle is provided with a pair of guide wheels that can contact the pair of side guide rails. In the vehicle, either one of the pair of guide wheels comes into contact with the side guide rail on one side, and the guide wheel receives a force in the width direction of the road from the side guide rail on one side. The vehicle travels in a direction along the side guide rail.

  By the way, in any method, when branching, the guide rail of the branching portion is bent at a certain angle with respect to the guide rail of the straight portion, so the guide wheel is relative to the guide rail of the branching portion, The contact is made at this fixed angle, and a relatively large impact is received.

  Therefore, for example, in the technique described in Patent Document 1 below, the guide rail of the branch portion is formed of a flexible material, so that the impact received by the guide wheels is reduced and the riding comfort is improved.

  The distance between the pair of guide surfaces of the guide rail is always the contact between the pair of guide wheels from the viewpoint of suppressing wear caused by the contact of the pair of guide wheels with the pair of guide surfaces at all times. The interval cannot be set. Specifically, in the central guide rail system, the distance between the pair of guide surfaces of the central guide rail is narrower than the gap distance between the pair of guide wheels.

  For this reason, even if the guide rail of the branch part is formed of a flexible material as in the technique described in Patent Document 1, the guide of the branch part is provided due to a gap between the guide wheel and the guide surface. There is a problem that the guide wheel receives an impact when contacting the rail, and the improvement of the ride comfort cannot be expected so much.

First, a first embodiment of a track traffic system according to the present invention will be described with reference to FIGS.

  The track system traffic system of this embodiment is a new traffic system of the center guide rail type, and includes a center guide type travel facility and a track system vehicle that travels on the travel path of the travel facility. First, a track system vehicle that travels on this traveling facility will be described with reference to FIGS. 7 and 8.

  The track system vehicle V according to the present embodiment includes a vehicle body 1 and a traveling device 10 disposed on each of the front and rear sides of the lower portion of the vehicle body 1. The track system vehicle V in the following description is simply referred to as a vehicle V.

  The traveling device 10 extends along a pair of left and right traveling tires 3, an axle 5 that connects the pair of traveling tires 3, a suspension device (not shown) that supports the axle 5 and the pair of traveling tires 3, and a central guide rail 20. And a steering guide device 11 for directing the traveling tire 3 in the selected direction. In the following description, regarding the vehicle V, when it is simply referred to as “vertical direction”, “front / rear direction”, and “left / right direction (vehicle width direction)”, these directions indicate that the track system vehicle is in a straight traveling portion. The direction based on the vehicle body 1 when positioned on the guide rail is assumed to be indicated. That is, the “vertical direction” means a direction perpendicular to the guide rail in a cross section perpendicular to the extending direction of the guide rail, “front-back direction” means the extending direction of the guide rail, The “left-right direction (vehicle width direction)” means the width direction of the vehicle V.

  The steering guide device 11 includes a king pin 12 that serves as a steering shaft of the traveling tire 3, a guide frame 13 that is disposed below an axle support (not shown) of the suspension device, and the guide frame 13 that is disposed on the floor surface of the vehicle body 1. A pivot bearing 14 that is pivotably supported around a vertical pivot axis A, a steering link mechanism 15 that changes the steering angle of the traveling tire 3 in conjunction with the pivot of the guide frame 13 around the pivot axis A, and a central guide rail 20. And a guide wheel 18 serving as a guide portion arranged in a line in the front-rear direction of the guide frame 13.

  The guide frame 13 forms a rectangular frame.

  As described above, the turning axis A of the turning bearing 14 is an axis perpendicular to the floor surface of the vehicle body 1 and passes through the center in the longitudinal direction of the axle 5, that is, an intermediate position between the pair of left and right traveling tires 3. is there. The pivot bearing 14 is disposed between the axle support (not shown) of the suspension device and the guide frame 13 in the vertical direction. The turning bearing 14 has an inner ring and an outer ring. One of the inner ring and the outer ring is fixed to the lower part of the axle support, and the other is fixed to the upper part of the guide frame 13. The center of the guide frame 13 in the front-rear direction and the left-right direction is located on the turning axis A.

  The steering link mechanism 15 includes a steering arm 16 that swings integrally with the traveling tire 3 with respect to the king pin 12 of the traveling tire 3, and a steering rod 17 that connects the steering arm 16 and the guide frame 13. ing. One end of the steering rod 17 is pin-coupled to the end of the steering arm 16, and the other end is pin-coupled to the guide frame 13.

  The outer periphery of the guide wheel 18 is formed of an elastic body such as urethane rubber. The main body 21 of the central guide rail 20 with which this guide wheel 18 contacts is formed of H-shaped steel. The H-shaped steel is arranged so that the outer surfaces of the pair of flanges 22 face in the vertical direction and the web 24 connecting the pair of flanges 22 faces in the horizontal direction, thereby forming the rail body 21. In the rail main body 21, the outer surface far from the other flange 22 among the surfaces of the pair of flanges 22 forms a guide surface 23. Here, H-shaped steel is used for the rail body 21, but the present invention is not limited to this, as long as there is a pair of surfaces that are parallel to each other and facing opposite directions, For example, I-shaped steel or railroad rails may be used. Moreover, as shown in FIG.7 and FIG.8, although the center guide rail 20 has a part formed only by the rail main body 21, the rail main body 21 and the induction | guidance | derivation part 60s are mentioned so that it may mention later using FIG. Some parts have

  The distance between the pair of guide surfaces 23 of the central guide rail 20 is narrower than the gap distance between the pair of guide wheels 18. This is because the guide wheels 18 are always in contact with the guide surface 23 to prevent the guide wheels 18 from being worn in a short period of time. This is for preventing deterioration of the riding comfort due to the guide wheel 18 being displaced in small increments due to the step of the surface 23 or the like.

  Next, operation | movement of the traveling apparatus 10 demonstrated above is demonstrated easily. When the vehicle V reaches a direction change portion such as a branching portion or a bent portion on the travel route, the guide wheel 18 positioned on the direction change side in the travel width direction with respect to the central guide rail 20 is the central guide rail 20. The center guide rail 20 receives a force in the vehicle width direction. This force is transmitted from the guide wheel 18 to the guide frame 13 and turns the guide frame 13 around the turning axis A. When the guide frame 13 turns, the steering rod 17 of the steering link mechanism 15 is displaced along with the turning, and the steering arm 16 and the traveling tire 3 rotate around the king pin 12 by this displacement. That is, the traveling tire 3 is steered.

  Next, the traveling equipment of this embodiment will be described.

  As shown in FIG. 1, the traveling facility according to the present embodiment includes a center guide disposed between a pair of left and right traveling roads R on which a pair of left and right traveling tires 3 of the vehicle travel and a pair of left and right traveling roads R, respectively. Rail 20. The traveling equipment includes a straight portion S where the vehicle V goes straight, a curved portion C (FIG. 5) where the traveling route of the vehicle V is bent, and a branching portion B where the traveling route of the vehicle V is branched. The straight traveling portion S, the bent portion C, and the branch portion B are provided with the above-described traveling path R and the central guide rail 20, respectively.

  The branch portion B is provided at an intersection between the travel main route ML in the travel route and the travel branch line route BL branched from the middle of the travel main route ML. The traveling facility further includes a branching mechanism 80 that changes the direction of the traveling path R and the central guide rail 20 in the branching section B. In the following description, it is assumed that the traveling main route ML is configured by the straight traveling portion S for the sake of simplicity.

  As shown in FIGS. 1 to 3, the branching mechanism 80 includes a center guide rail 20 (hereinafter referred to as a branching portion rail 20 b) of the branching portion B and a base 81 provided with a traveling path R on the upper side, and a branch start. And a switch 82 for turning the base 81 around a base turning shaft 85 provided at the position BC. The switch 82 has a main line guide position (FIG. 1) in which the branch rail 20b and the branch road R on the base 81 face in the main line direction MR along the main road route ML, and along the driving branch line BL. The base 81 is turned around the base turning shaft 85 between the branch guide rail 20b on the base 81 and the branch guide position (FIG. 2) in which the branch running path R faces in the branch direction BR.

  The base turning shaft 85 is on the extension line of the guide surface 23si on the direction change side of the central guide rail 20 (hereinafter referred to as the straight portion rail 20s) of the straight portion S, and is the aforementioned branch start position BC where the branch starts. Is provided. The base 81 extends to the front side and the front side in the traveling direction of the main line direction MR with respect to the base turning shaft 85 at the main line guide position. The traveling path R on the base 81 is provided from the end of the base 81 to the end, that is, from the front end in the traveling direction of the base 81 to the front end in the traveling direction. On the other hand, the branch rail 20 b on the base 81 is provided from the branch start position BC, which is the position of the base turning shaft 85, to the front end in the traveling direction of the base 81. On the base 81, between the front end in the traveling direction and the branch start position BC, the straight portion rail 20s of the straight portion S provided on the near side in the traveling direction of the branch portion B extends. Yes. The end of the straight portion rail 20s is supported by the base turning shaft 85, but it does not turn even if the base 81 turns.

  In the base 81 and the traveling path R on the base 81, the shape of the front end in the traveling direction and the front end in the traveling direction form an arc shape with the branch start position BC as the center. In addition, the traveling path R of the straight portion S also has an arc shape with the end of the branch portion B side being centered on the branch start position BC.

  The switch 82 extends in the travel path width direction with respect to the travel main path ML, and has a rod 84 whose tip is attached to the base 81, and a drive source that moves the rod 84 in the travel path width direction with respect to the travel main path ML. 83. As the drive source 83, a hydraulic cylinder, an electromagnetic cylinder, an electric motor, or the like is used. Here, the output of the drive source 83 is transmitted to the base 81 via a single rod 84, but the output of the drive source 83 is transmitted to the base 81 via a plurality of gears and a plurality of links. Also good. In particular, when an electric motor is used as a drive source, it is necessary to change the rotational motion of the drive source to a linear motion using, for example, a rack and a pinion.

  As shown in FIG. 4, the rectilinear portion rail 20s of the rectilinear portion S provided on the front side in the advancing direction of the branch start position BC (hereinafter, referred to as the front straight portion rail (front portion rail) 20ss) is the above-described H The rail main body 21 made of steel and the front side in the traveling direction of the rail main body 21, that is, the branch start position BC side, and the direction change side (hereinafter referred to as the in side) in the travel path width direction are: And a guide portion 60s provided on the opposite side (hereinafter referred to as the out side).

  Of the pair of guide surfaces 23si, 23so of the front straight portion rail 20ss, the guide portion 60s includes a guide surface 61s that forms part of the out-side guide surface 23so, and the guide surface 61s as it approaches the branch start position BC. A width-shifting portion 62s that gradually moves away from the in-side guide surface 23si is provided. For this reason, the width between the pair of guide surfaces 23si and 23so of the front straight portion rail 20ss gradually increases as it approaches the branch start position BC, and becomes the maximum width near the branch start position BC. Yes. This maximum width is substantially the same as the gap interval Wa between the pair of guide wheels 18.

  The guiding portion 60s is formed such that its guiding surface 61s is continuous with the guide surface 23so on the out side of the rail main body 21. The angle θs in the direction in which the guide surface 61s extends with respect to the main line direction MR is smaller than the angle θb of the branch direction BR with respect to the main line direction MR, for example, 1 ° or less.

  A branch rail 20b, which is the central guide rail 20 of the branch B, is a rail main body 21 formed of the above-described H-shaped steel, and a front side in the traveling direction of the rail main body 21, that is, a branch start position BC side. And a guiding portion 60b provided on the out side.

  The guide portion 60b includes a guide surface 61b that forms part of the out-side guide surface 23bo of the pair of guide surfaces 23bi and 23bo of the branch portion rail 20b, and the guide surface 61b as the distance from the branch start position BC increases. A width-shifting portion 62b that gradually approaches the side guide surface 23bi is provided. For this reason, the mutual width of the pair of guide surfaces 23bi and 23bo of the branch portion rail 20b is the maximum width at the branch start position BC and gradually decreases as the distance from the branch start position BC increases. This maximum width is also substantially the same as the gap interval Wa between the pair of guide wheels 18, as is the maximum width of the pair of guide surfaces 23 si and 23 so of the front straight portion rail 20 ss.

  Therefore, when the branch rail 20b is at the main guide position, the pair of guide surfaces 23bi and 23bo of the branch rail 20b has continuity with the pair of guide surfaces 23si and 23so of the front straight track 20ss. doing. However, when the branch rail 20b is in the branch guide position, this branch is centered on the base turning shaft 85 (FIGS. 1 and 2) located on the extension line of the in-side guide surface 23si of the front straight rail 20ss. Since the portion rail 20b is turning, the continuity between the in-side guide surface (changed portion guide surface) 23bi of the branch portion rail 20b and the in-side guide surface 23si of the front straight portion rail 20ss is maintained. The out side guide surface 23bo of the branch portion rail 20b is separated from the out side guide surface 23so of the front straight portion rail 20ss, and the continuity is not maintained.

  Each of the guide portion 60s of the front straight portion rail 20ss and the guide portion 60b of the branch portion rail 20b is formed by combining steel plates or by processing L-shaped steel, H-shaped steel, or the like.

  Next, the operation of the vehicle V entering the branch part B from the straight ahead part S when the base 81 of the branch mechanism 80 is located at the branch guide position will be described.

  At a position on the near side in the traveling direction of the guide portion 60s of the front straight portion rail 20ss, the pair of guide wheels 18 is in a state of not contacting any of the pair of guide surfaces 23si and 23so of the front straight portion rail 20ss. In other words, only one guide wheel 18 is in contact with one guide surface 23.

  Temporarily, the pair of guide wheels 18 goes straight in the main line direction MR until the pair of guide wheels 18 are not in contact with any of the pair of guide surfaces 23si and 23so of the front straight portion rail 20ss, and the branch rail 20b at the branch guide position. As a result, the in-side guide wheel 18i of the pair of guide wheels 18 suddenly contacts the in-side guide surface 23bi of the branch rail 20b, and the in-side guide wheel 18i receives a relatively large impact force. For this reason, the turning angle of the guide frame 13 provided with the in-side guide wheel 18i is instantaneously considerably larger than the angle of the branch direction θb with respect to the main line direction MR, and the riding comfort is deteriorated.

  On the other hand, in the present embodiment, when the pair of guide wheels 18 enters the area where the guide part 60s of the front straight part rail 20ss is provided, the guide surface 61s which is the out-side guide surface 23so starts to branch in this area. As it approaches the position BC, it gradually moves away from the in-side guide surface 23si, so that the out-side guide wheel 18o of the pair of guide wheels 18 is surely placed on the guide surface 61s at any position in this region. To touch. As a result, the out-side guide wheel 18o gradually moves away from the in-side guide surface 23si as it approaches the branch start position BC, while the in-side guide wheel 18i paired with the out-side guide wheel 18o gradually increases. Approaches the in-side guide surface 23si. When the pair of guide wheels 18 reaches the branch start position BC, the mutual width of the pair of guide surfaces 23 of the front straight portion rail 20ss at the branch start position BC is equal to the pair of guide wheels 18 as described above. Since the gap interval Wa is substantially the same, the pair of guide wheels 18 are substantially in contact with the guide surface 23.

  As described above, the in-side guide surface 23si of the front straight portion rail 20ss and the in-side guide surface (change portion guide surface) 23bi of the branch portion rail 20b are either the main line guide position or the branch guide position. It is continuous. For this reason, if the in-side guide wheel 18i is in contact with the in-side guide surface 23si of the front straight portion rail 20ss at the branch start position BC, the in-side guide wheel 18i is guided to the in-side guide of the front straight portion rail 20ss. It will contact the in-side guide surface (changed portion guide surface) 23bi of the branch rail 20b while being in contact with the surface 23si.

  Therefore, in this embodiment, the impact caused by the in-side guide wheel 18i suddenly contacting the in-side guide surface 23i of the branch rail 20b at the branch guide position can be reduced.

A guide surface 61s that forms part of the surface 23so and a width-shifting portion 62s that gradually moves the guide surface 61s away from the in-side guide surface 23si as it approaches the bending start position BC. The bend start position BC is a contact position between the central guide rail 20 of the bent portion C (hereinafter referred to as a bent portion rail 20c) and the front straight portion rail 20ss.

  Further, similarly to the branch portion rail 20b, the bent portion rail 20c is the rail main body 21 formed of the above-described H-shaped steel and the front side in the traveling direction of the rail main body 21, that is, the bending start position BC side. It has the guidance part 60c provided in the out side.

  The guide portion 60c also includes a guide surface 61c that forms part of the out-side guide surface 23co, and a guide surface 61c that moves away from the bending start position BC, out of the pair of guide surfaces 23ci and 23co of the bent portion rail 20c. And a width-shifting portion 62c that gradually approaches the side guide surface 23ci.

  In this way, by providing the guiding portion 60s also on the front straight traveling portion rail 20ss provided on the front side in the traveling direction of the bending portion C, in the process where the pair of guide wheels 18 reaches the bending start position BC, The guide wheel 18i substantially contacts the in-side guide surface 23si of the front straight portion rail 20ss, and the in-side guide wheel 18i suddenly contacts the in-side guide surface (changed portion guide surface) 23ci of the bent portion rail 20c. The impact caused by contact can be reduced.

  As mentioned above, in this embodiment, in the direction change part containing the branch part B and the curved part C, the impact by the guide wheel 18 which is a guide part suddenly contacting the center guide rails 20b and 20c of this direction change part is relieved. Can improve ride comfort.

  In the present embodiment, as shown in FIG. 4, the rail body 21 of the branch rail 20b is linear, and the rail body 21 at the branch guide position extends straight along the travel branch line path BL. The branch start position BC is coincident with the position of the intersection point IP between the travel branch line route BL and the travel main line route ML. However, as shown in FIG. 6, the rail main body 21 of the branch portion rail 20b is smoothly curved, and the rail main body 21 at the branch guide position is gradually bent along the travel branch line route BL. In this case, the branch start position BC is located on the near side in the traveling direction with respect to the intersection IP that is the intersection of the travel branch line route BL and the travel main route route ML. As described above, when the rail main body 21 of the branch portion rail 20b is smoothly curved at the branch guide position so as to follow the travel branch line route BL, the input of the straight portion rail 20ss at the branch start position BC. The angle formed by the side guide surface 23si and the in-side guide surface 23bi of the branch portion rail 20b can be reduced, and the impact received by the guide wheel 18 can be further reduced.

  Next, the traveling equipment of this embodiment will be described.

  As shown in FIG. 9, the traveling facility of the present embodiment includes a traveling path R on which a pair of left and right traveling tires 3 of the vehicle Va respectively travel, side guide rails G disposed on both sides of the traveling path R, It has. Similarly to the traveling facility of the first embodiment, the traveling facility also includes a straight traveling portion S where the vehicle Va goes straight, a curved portion C (FIG. 13) where the traveling route of the vehicle Va bends, and a traveling route of the vehicle Va. There is a branch B. The straight traveling portion S, the bent portion C, and the branch portion B are provided with the above-described traveling path R and side guide rail G, respectively.

  The branch portion B is provided at the intersection of the travel main route ML in the travel route and the travel branch line route BL that branches from the middle of the travel main route ML. A pair of main guide rails 30 with which the main guide wheels 18 of the vehicle Va contact are provided as side guide rails G in the straight traveling portion S and the bent portion C (FIG. 13). In addition, as a side guide rail G, a pair of branch guide rails 34 in contact with the branch guide wheels 19 of the vehicle Va as well as a pair of main guide rails 30 in contact with the main guide wheels 18 of the vehicle Va are provided at the branch portion B. , 35 are provided. In the following description, it is assumed that the traveling main route ML is configured by the straight traveling portion S for the sake of simplicity.

  The main guide rails 30 in the straight portion S, the bent portion C, and the branch portion B are provided along the travel path R on both sides of the travel path R. That is, the main guide rails 30 exist on the left and right sides of the vehicle Va, and form a pair. The rail main body 31 of the main guide rail 30 is formed of H-shaped steel as shown in FIGS. The H-shaped steel is arranged such that the outer surfaces of the pair of flanges 32 face in the vertical direction, and the web 34 w connecting the pair of flanges 32 faces in the horizontal direction, thereby forming the rail body 31. In the rail main body 31, the surface on the other rail main body 31 side facing the rail main body 31 through the traveling path R among the surfaces of the pair of flanges 32 forms a main guide surface 33. In addition, although H-type steel is used for the rail main body 31 here, this invention is not limited to this, I-type steel etc. may be used.

  Of the rail main bodies 31 of the pair of main guide rails 30, the distance Wb (FIG. 15) between the main guide surface 33 of one rail main body 31 and the main guide surface 33 of the other rail main body 31 is a pair of main guide wheels. It is wider than 18 outer edge intervals Wc. This is because each of the pair of main guide wheels 18 is always in contact with the main guide surface 33 to prevent the main guide wheels 18 from being worn in a short period of time. This is because, for example, to prevent deterioration of the riding comfort due to the main guide wheel 18 being displaced in small increments due to a step or the like of the main guide surface 33 at a joint or the like.

  As shown in FIG. 13, among a pair of main guide rails 30 and 30 (hereinafter referred to as front rails 30si and 30so) provided in the straight forward portion S on the front side in the traveling direction of the bent portion C, the in side The front rail 30si is a rail main body 31 formed of the above-described H-shaped steel, and a leading side in the traveling direction of the rail main body 31, that is, a bending start position BC side, and an induction provided on the out side thereof. Part 60s. On the other hand, out of the pair of front rails 30si and 30so, the out-side front rail 30so is formed of only the rail main body 31. The bend start position BC is the position of the front end of the bent portion C in the traveling direction of the main guide rail 30, that is, the front guide rail 30si which is the main guide rail 30 of the bent portion C and the main guide rail 30 of the straight portion S. , 30 so.

  The guiding portion 60s gradually moves the guiding surface 61s that forms a part of the main guide surface 33si of the in-side front rail 30si and the guiding surface 61s toward the out-side front rail 30so as it approaches the bending start position BC. And a width-adjusting portion 62s that is brought closer. For this reason, the width between the main guide surfaces 33si and 33so of the pair of front rails 30si and 30so gradually decreases as the branch start position BC is approached, and is the maximum near the branch start position BC. It is narrow. This minimum width is substantially the same width as the distance Wc between the innermost surface of the outer peripheral surface of the in-side main guide wheel 18i and the outermost surface of the outer peripheral surface of the out-side main guide wheel 18o. is there.

  The guiding portion 60s is formed such that its guiding surface 61s is continuous with the main guide surface 33si of the rail body 31. The angle of the direction in which the guide surface 61s extends with respect to the main guide surface 33si of the rail body 31 is, for example, 1 ° or less.

  Among a pair of main guide rails 30 (hereinafter referred to as bent portion rails 30ci and 30co) provided in the bent portion C, the in-side bent portion rail 30ci includes a rail body 31 formed of the aforementioned H-shaped steel. The rail main body 31 has a guide portion 60c provided on the front side in the traveling direction, that is, on the bending start position BC side and on the out side thereof. On the other hand, of the bent portion rails 30ci and 30co, the out-side bent portion rail 30co is formed by only the rail main body 31.

  The guide portion 60c gradually approaches the guide surface 61c that forms a part of the main guide surface 33i of the in-side bent portion rail 30ci and the guide surface 61c toward the in-side as the distance from the bending start position BC increases. The side bent portion rail 30ci has a width-shifting portion 62c that is continuous with the main guide surface 33i of the rail main body 31.

  Each of the guide portion 60s of the in-side front portion rail 30si and the guide portion 60c of the bent portion rail 30ci is formed by combining steel plates, processing L-shaped steel, H-shaped steel, or the like.

  Next, the operation of the vehicle Va in the process of moving from the straight portion S on the near side in the traveling direction of the bent portion C to the bent portion C will be described.

  As shown in FIG. 13, the pair of main guide wheels 18 are located on the main guide surfaces 33si and 33so of the pair of front rails 30si and 30so at the position on the front side in the traveling direction of the guide portion 60s of the in-side front rail 30si. Either one of the main guide wheels 18 is in contact with one main guide surface 33.

  If the pair of main guide wheels 18 goes straight in a state where they are not in contact with any of the main guide surfaces 33si and 33so of the pair of front rails 30si and 30so, and reaches the bent portion C, the pair of main guides Out-side main guide wheel 18o of wheels 18 suddenly contacts main guide surface 33co of out-side bent portion rail 30co at a predetermined angle, and out-side main guide wheel 18o has a relatively large impact force. receive. For this reason, the guide lateral beam 13b of the steering guide device 11a provided with the out-side main guide wheel 18o is momentarily greatly displaced in the vehicle width direction, and the forward / reverse lever plate 14a is displaced due to this displacement, thereby the steering. The arm 16 and the running tire 3 rotate greatly around the kingpin 12. For this reason, the steering angle of the traveling tire 3 increases momentarily considerably, and the ride comfort deteriorates.

  On the other hand, in the present embodiment, when the pair of main guide wheels 18 enter the region where the guide portion 60s of the in-side front rail 30si is provided, in this region, the main guide surface 33i of the in-side front rail 30si. As the guide surface 61s is gradually approaching the out-side front rail 30so as it approaches the bend start position BC, the in-side main guide wheel 18i is guided to the guide surface 61s at any position within this region. To make sure it comes into contact. As a result, the pair of main guide wheels 18 gradually approach the out side as they approach the bend start position BC. When the pair of main guide wheels 18 reaches the bending start position BC, the mutual widths of the main guide surfaces 33si and 33so of the pair of front rails 30si and 31so at the bending start position BC are the in-side main widths. Since the innermost surface of the outer peripheral surface of the guide wheel 18i and the outermost surface of the outer main surface of the out side main guide wheel 18o have substantially the same width Wb, a pair of main guide wheels 18 is in a state of being substantially in contact with the main guide surface 33.

  By the way, the main guide surface 33so of the out side front portion rail 30so and the main guide surface (change portion guide surface) 33co of the out side bent portion rail 30co are continuous. For this reason, when the out side main guide wheel 18o is in contact with the main guide surface 33so of the out side front portion rail 30so at the bending start position BC, the out side main guide wheel 18o is connected to the out side front portion rail 30so. From the state in contact with the main guide surface 33so, it smoothly transitions to the main guide surface (changed portion guide surface) 33co of the bent portion rail 30co continuous with the main guide surface 33so, and comes into contact with the main guide surface 33co. Will do.

  Therefore, in the present embodiment, it is possible to reduce the impact caused by the out side main guide wheel 18o suddenly contacting the main guide surface (change portion guide surface) 33co of the out side bent portion rail 30co at a predetermined angle. For this reason, it is possible to prevent a deterioration in riding comfort due to a momentary increase in the steering angle of the traveling tire 3.

  When the vehicle Va enters the branch part B from the straight part S, the out-side branch guide wheel 19o out of the pair of branch guide wheels 19i and 19o is inward from the straight-ahead guide surface 38o of the out-side movable branch rail 35o. The straight travel guide surface 38o is not touched during travel of the branch portion B, and the travel restriction by the straight travel guide surface 38o is not imposed. Of the pair of main guide wheels 18i, 18o, the out-side main guide wheel 18o is located on the in-side from the main guide surface 33bo of the out-side branching section main rail 30bo. There is no contact with the guide surface 33bo, and no movement restriction is imposed by the main guide surface 33bo.

  On the other hand, when the vehicle enters the branch part B from the straight part S, the in-side branch guide wheel 19i has an outer side surface of the outer side surface thereof that is a branch guide surface (change part guide surface) 38i of the in-side movable branch rail 35i. Proximity. Further, the in-side main guide wheel 18i has an in-side surface of the outer peripheral surface thereof close to the main guide surface 33bi of the in-side branch portion main rail 30bi of the branch portion B. That is, the in-side branch guide wheel 19i is restricted from moving outward by the branch guide surface 38i of the in-side movable branch rail 35i existing on the out side, and the in-side main guide wheel 18i is in the in-side. Movement to the in side is restricted by the main guide surface 33bi of the in-side branching section main rail 30bi that exists.

  Therefore, when the vehicle Va enters the branch portion B, the in-side branch guide wheel 19i rolls in contact with the branch guide surface (change portion guide surface) 38i of the in-side movable branch rail 35i, or the in-side main guide. The wheel 18i rolls in contact with the main guide surface 33bi of the in-side branch portion main rail 30bi. For this reason, when the vehicle Va enters the branch portion B, the in-side branch guide wheel 19i or the in-side main guide wheel 18 receives a force in the vehicle width direction, and the guide cross beam 13b of the steering guide device 11a is displaced in the vehicle width direction. As a result of this displacement, the forward / reverse lever plate 14a is displaced, and the steering arm 16 and the traveling tire 3 rotate around the kingpin 12. That is, the traveling tire 3 is steered.

  Here, when the movable branch rail 35 is located at the branch guide position, the operation of the vehicle Va in the process in which the vehicle Va moves from the straight portion S on the near side in the traveling direction of the branch portion B to the branch portion B. This will be described in more detail.

  When the movable branch rail 35 is located at the branch guide position, as described above with reference to FIG. 14, the approach end side end of the branch guide surface 38 i of the in-side movable branch rail 35 i is located on the in-side fixed branch rail 34 i. The branch guide surface 38i is located at substantially the same position in the traveling direction width direction as the front end in the traveling direction of the branch guide surface 38i, and the branch guide surface 38i of the in-side movable branch rail 35i is the travel direction of the in-side fixed branch rail 34i. It is a position facing the direction (branch direction BR) along the branch guide surface 38i on the near side.

  Furthermore, when the movable branch rail 35 is located at the branch guide position, the position of the front end in the traveling direction of the branch guide surface 38i of the in-side movable branch rail 35i is the in-side front portion rail 30si in the travel path width direction. The position of the main guide surface 33si where the guide portion 60s is not provided is located on the outer side than the outer diameter of the branch guide wheel 19.

  The pair of main guide wheels 18 are not in contact with any of the main guide surfaces 33si and 33so of the pair of front rails 30si and 30so at the position on the front side in the traveling direction of the guide portion 60s of the in-side front rail 30si. In this state, only one main guide wheel 18 is in contact with one main guide surface 33s.

  Assuming that none of the pair of main guide wheels 18 is in contact with the main guide surfaces 33si, 33so of the rail bodies 31, 31 of the pair of front rails 30si, 30so, go straight in the main line direction MR, Upon reaching the in-side movable branch rail 35i at the branch guide position, the in-side branch guide wheel 19i suddenly moves inward to the in-side movable branch in a state where neither the main guide wheel 18 nor the branch guide wheel 19 is in contact with the guide surface. The inboard branch guide wheel 19i comes into contact with the branch guide surface (change portion guide surface) 38i of the rail 35i and receives a relatively large impact force, so that the riding comfort is deteriorated.

  On the other hand, in this embodiment, when the pair of main guide wheels 18 enters the area where the guide part 60s of the in-side front part rail 30si is provided, the guide surface that is the in-side main guide surface 33si in this area. As 61s approaches the branch start position BC, the inward main guide wheel 18i is surely in contact with the guide surface 61s at any position within this region. As a result, together with the in-side main guide wheel 18i, the in-side branch guide wheel 19i gradually goes to the out side and approaches the branch guide surface 38i of the in-side movable branch rail 35i as it approaches the branch start position BC. When the pair of main guide wheels 18 reaches the branch start position BC, the in-side branch guide wheel 19i substantially contacts the branch guide surface (change portion guide surface) 38i of the in-side movable branch rail 35i. become.

  Therefore, in the present embodiment, in the process in which the vehicle Va moves from the front side in the traveling direction of the branching portion B to the branching portion B, the guidance corresponding to either the in-side main guide wheel 18i or the in-side branching guide wheel 19i corresponds. The surfaces 33si and 38i are in contact with each other. For this reason, in the present embodiment, the in-side branch guide wheel 19i suddenly has the in-side movable branch rail 35i in a state where neither the in-side main guide wheel 18i nor the in-side branch guide wheel 19i is in contact with the corresponding guide surface. The impact due to contact with the branch guide surface (change portion guide surface) 38i can be alleviated, and deterioration of ride comfort can be prevented.

  As described above, also in the present embodiment, as in the first embodiment, in the direction change portion including the branch portion B and the bent portion C, the impact caused by the guide wheels 18 and 19 suddenly contacting the guide rail of the direction change portion is reduced. Can improve ride comfort.

  Next, a modified example of the guide rail having the guide portion 60s will be described.

"First variation of guide rail"
First, the 1st modification of a guide rail is demonstrated using FIG.16 and FIG.17.

  As shown in FIG. 16, the guide rail of the present modification is a central guide rail 20 a, and supports the rail body 21 formed of H-shaped steel, the leaf spring 71, and one end portion of the leaf spring 71. It has a shaft 75 and a cradle 76 to which the other end of the leaf spring 71 is fixed. In the present modification, the leaf spring 71, the support shaft 75, and the cradle 76 constitute the guide portion 70.

  Of the pair of flanges 22a and 22b of H-shaped steel forming the rail main body 21, one flange 22a is partially cut away. A support shaft 75 is fixed to the front side in the advancing direction in the notched portion, perpendicular to the H-shaped steel web 24 and parallel to the flange 22a. Further, as shown in FIG. 17, a pedestal 76 is fixed to the front end portion in the advancing direction of the flange 22 a on the side that is partially cut away. The pedestal 76 is L-shaped steel, and one of the two flanges 76 a and 76 b orthogonal to each other has one flange 76 a opposed to the flange 22 a of the rail body 21, and the other flange 76 b has the end portion of the rail body 21 flange. It is fixed to 22a. One flange 76a of the pedestal 76 has a notch 77a cut out from one side in the thickness direction to an intermediate position in the thickness direction of the flange 76a, and the flange 76a from the other side in the thickness direction. Cutout portions 77b cut out to an intermediate position in the thickness direction are alternately formed in the height direction of the flange 22a of the rail body 21.

  As shown in FIG. 16, the leaf spring 71 has a main surface 72 perpendicular to the plate thickness direction facing the flange 22 b of the rail body 21, and the main surface 72 is predetermined with respect to the flange 22 a of the rail body 21. The front end portion in the traveling direction is attached to the support shaft 75 and the front end portion in the traveling direction is attached to the pedestal 76 so as to be inclined at an angle. The front end of the leaf spring 71 in the traveling direction is wound around the support shaft 75 so that the front side in the traveling direction can swing around the support shaft 75. Further, as shown in FIG. 17, the front end in the traveling direction of the leaf spring 71 has a plurality of cuts parallel to the longitudinal direction of the leaf spring 71 at different positions in the height direction of the flange 22 a of the rail body 21. It is. A plurality of fractional pieces 73 partitioned by a plurality of cuts are formed. The plurality of segment pieces 73 are fitted into the notches 77a and 77b of the receiving portion 76, respectively.

  Of the pair of main surfaces 72 of the leaf spring 71 which is an elastic body, the main surface 72 on the side farther from the flange 22b of the rail body 21 forms a guide surface 72s. The guide surface 72s forms a predetermined angle with respect to the flange 22a of the rail body 21 and the guide surface of the rail body 21 at the end of the leaf spring 71 on the support shaft 75 side, like the guide surfaces in the above embodiments. 23 is substantially continuous. This predetermined angle is, for example, 1 ° or less.

  As described above, in this modified example, since the guide portion 70 has the leaf spring 71, when the guide wheel 18 contacts the guide surface 72s of the guide portion 70, the leaf spring 71 of the guide portion 70 is elastic. By deforming, the impact when the guide wheel 18 contacts the guide surface 72s can be reduced. Therefore, riding comfort can be improved as compared with the guide rails of the above-described embodiments having the high-rigidity guide portion 60s formed of a steel plate, a mold steel, or the like.

  In this modified example, the cradle 76 is formed of L-shaped steel, but instead of this, other shaped steel or a combination of a plurality of steel plates may be used. Moreover, although the rail main body 21 is formed with the H-shaped steel in the present modified example and the following modified examples, other steel shapes or a combination of a plurality of steel plates may be used instead.

"Second modification of guide rail"
Next, the 2nd modification of a guide rail is demonstrated using FIG.

  The guide rail of this modification is also a central guide rail 20d, and has a rail main body 21 formed of H-shaped steel and a leaf spring 71b that constitutes a guide portion.

  Of the pair of flanges 22a and 22b of H-shaped steel forming the rail main body 21, one flange 22a is cut out from the middle to the position of the front end in the traveling direction. A leaf spring 71b is disposed in the notched portion. The leaf spring 71b has a main surface 72b perpendicular to the plate thickness direction facing the flange 22b of the rail body 21, and the main surface 72b is inclined at a predetermined angle with respect to the flange 22a of the rail body 21. The front end portion in the traveling direction is joined to one flange 22a of the rail body 21. On the other hand, the front end of the leaf spring 71b in the traveling direction is not supported at all. That is, in the first modification, the leaf spring 71 is supported at both ends, but in the present modification, the leaf spring 71b is cantilevered. For this reason, the leaf spring 71b of the present modification has a larger elastic coefficient in the direction between the pair of flanges of the rail main body 21 (running path width direction) than the elastic coefficient of the leaf spring 71 of the first modification. .

  Of the pair of main surfaces 72b of the leaf spring 71b, which is an elastic body, the main surface 72b far from the flange 22a of the rail body 21 forms a guide surface 72s. When the leaf spring 71b is in a natural state, the guide surface 72s forms a predetermined angle with respect to the flange 22 of the rail main body 21 in the same manner as the guide surface in each of the embodiments and the first modification described above. It is continuous with the guide surface 23 which is the flange 22a of the rail main body 21 at the end. This predetermined angle is, for example, 1 ° or less.

  As described above, also in the present modified example, when the guide wheel 18 contacts the guide surface 72s, the leaf spring 71b, which is an elastic body, elastically deforms and contacts the guide wheel 18 with the guide surface 72s, as in the first modified example. This can alleviate the impact and improve the ride comfort. Moreover, in this modification, a structure can be simplified rather than the guide rail of a 1st modification.

"Third modification of guide rail"
Next, the 3rd modification of a guide rail is demonstrated using FIG.

  The guide rail of this modification is also a central guide rail 20e, a rail main body 21 formed of H-shaped steel, a steel plate (guide face plate) 71c, a support shaft 75 that supports one end of the steel plate 71c, and a steel plate. And an elastic body 77 that elastically supports the other end of 71c. In the present modification, the steel plate 71c, the support shaft 75, and the elastic body 77 constitute the guide portion 70c.

  Of the pair of flanges 22a and 22b of the H-shaped steel forming the rail body 21, one flange 22a is cut out from the middle to the position of the front end of the H-shaped steel in the traveling direction. A support shaft 75 is fixed to a portion on the front side in the traveling direction in the cut-out portion so as to be perpendicular to the H-shaped steel web 24 and parallel to the flange 22a. Further, one end of the elastic body 77 is fixed to the front side in the moving direction of the flange 22b that is not cut and to the web 24 side.

  The steel plate 71c has a main surface 72c perpendicular to the thickness direction of the steel plate 71c facing the flange 22b of the rail body 21 and the main surface is inclined at a predetermined angle with respect to the flange 22a of the rail body 21. A side end is attached to the support shaft 75, and a front end in the traveling direction is attached to the other end of the elastic body 77. The front end in the traveling direction of the steel plate 71c is wound around the support shaft 75 so that the front side in the traveling direction can swing around the support shaft 75.

  Of the pair of main surfaces 72c of the steel plate 71c, the main surface 72c far from the flange 22 of the rail main body 21 forms a guide surface 72s. When the elastic body 77 has a natural length, the guiding surface 72s forms a predetermined angle with respect to the flange 22a of the rail main body 21 as in the guiding surfaces 72s in the above-described embodiments and the first modification, and the progress thereof. It is substantially continuous with the guide surface 23 of the rail body 21 at the end on the front side in the direction. This predetermined angle is, for example, 1 ° or less.

  As described above, even if the guiding portion 70c is formed by the elastic body 77 and the steel plate 71c forming the guiding surface 72s, when the guide wheel 18 contacts the guiding surface 72s, the elastic body 77 is formed as in the first modification. Is elastically deformed, and the impact when the guide wheel 18 comes into contact with the guide surface 72s can be mitigated, and the riding comfort can be improved. In this modification, the elastic coefficient of the derivative can be easily changed by replacing the elastic body 77.

  Here, a coil spring may be used as the elastic body 77, but as shown in FIG. 20, a resin such as urethane rubber or 6 nylon may be used. Further, as shown in FIG. 21, neither of the pair of flanges 22a and 22b of the H-shaped steel forming the rail main body 21 is cut out, and an elastic body 77 is formed between the end of one flange 22a and the steel plate 71c. The aforementioned urethane rubber or the like may be disposed. In addition, as shown in FIG. 22, a coil spring 77d as an elastic body is disposed between the flange 22b of the rail body 21 and the steel plate 71c, and a damper 78d as a shock absorber or a vibration control device is disposed. Good. As described above, when the damper (damper) 78d is used together with the coil spring 77d and the like, the vibration generated when the steel plate 71c contacts the guide wheel 18 can be converged in a short time.

  In addition, although the above each modification is an example which deform | transformed the center guide rail 20 in 1st embodiment, it cannot be overemphasized that the main guide rail 30 of the side guide rail G in 2nd embodiment can be deform | transformed similarly.
