[0021]
Hereinafter, the organization of this dual mode vehicle traffic system and its release will be described.
[0022]
FIG. 5 is a schematic diagram of organization and release of a dual mode vehicle traffic system that can be used for both railway and road, showing an embodiment of the present invention.
[0023]
(1) First, as shown in FIG. 5 (a), the vehicle is in a mode as a normal road surface traveling vehicle (bus) 11 that runs on the land road 10.
[0024]
(2) Next, in order to set the mode of the railway vehicle, as shown in FIG. 5B, the carriage 1 is set at the place where the stopper devices 23 and 24 having the rails 21 are arranged, The vehicle 11 is moved forward by driving the rear wheel 12 of the vehicle 11 by driving the air spring lifting device 15 on the front wheel 14 side of the vehicle 11 to raise the front of the vehicle 11, that is, the vehicle height.
[0025]
(3) Next, as shown in FIG. 5C, the front wheel 14 of the vehicle 11 is held in the recess 2 </ b> A (see FIG. 3) of the tire carrier 2 of the carriage 1. Therefore, the air spring lifting / lowering device 15 of the vehicle 11 is driven to lower the front of the vehicle 11 (lower the vehicle height), and the vehicle locking pin 18 (see FIG. 4) is used by the locking device 18 of the vehicle 11. The lock body 18A (see FIG. 4) descends from above (step 1), and is then tightened (step 2), locked, assembled, and the front of the vehicle 11 is firmly locked. When unlocking, on the contrary, the locked locking body 18A (see FIG. 4) is loosened and then pulled upward.
[0026]
Therefore, the knitting of the dual mode vehicle is finished, the stopper devices 23 and 24 are removed, the rear wheel 12 of the vehicle is rotated by driving the prime mover 13 of the vehicle 11, and the rear wheel 12 is a tire travel path (tire travel plate). Begins advancing by friction with 22 The carriage 1 travels on the rail 21. The carriage 1 has a steering mechanism and proceeds along the rail 21. However, when it is necessary to apply a brake, as shown in FIG. 2, the carriage 1 is driven by a working fluid pressure generated by a compressor 16 or a hydraulic pump. The brake device 17 can be operated to brake the vehicle 11 along with the speed control of the vehicle 11. The brake device 17 may be a tread pressing method or a side disk (ring center disk) system. Rather, the side disk (ring center disk) method is more effective.
[0027]
In addition, the travel path provided along the track is minimal, and when the vehicle (bus) travels on the track, the front wheel of the carriage 1 is flange-guided in the same manner as the railroad vehicle, so that the handle becomes free.
[0028]
(4) And when releasing the dual mode vehicle traffic system, as shown in FIG. 5 (d), the stopper devices 23, 24 are arranged before and after the carriage 1, and the locking device 18 of the vehicle 11 is installed. After releasing the front of the vehicle from the vehicle locking pin 4, the air spring lifting / lowering device 15 is driven to raise the front of the vehicle 11 (the vehicle height is raised). By driving the prime mover 13, the rear wheel 12 of the vehicle is rotated in the reverse direction, and the vehicle 11 is returned.
[0029]
(5) Next, as shown in FIG. 5 (e), the air spring lifting / lowering device 15 of the vehicle 11 is driven to lower the front of the vehicle 11 (lower the vehicle height) and travel on the land road 10. The normal road surface traveling vehicle (bus) 11 is returned to the mode.
[0030]
In this way, these trajectory conversions can be performed with passengers on.
[0031]
In addition, after pulling out the trolley | bogie 1, the vehicle (bus | bath) 11 can go out to a general driving | running route, and it cannot be overemphasized that the convenience improvement and effect by direct communication are possible.
[0032]
Moreover, although the above-mentioned trolley | bogie 1 was demonstrated as a 2-axis trolley | bogie, as shown below, you may comprise so that it may be a 3-shaft trolley | bogie.
[0033]
FIG. 6 is a schematic view of a three-shaft carriage showing another embodiment of the present invention.
[0034]
As shown in this figure, the triaxial cart 31 includes a tire carrier 32 having a front wheel 33, an intermediate wheel 34, and a rear wheel 35, and the position of a recess 32 </ b> A of the tire carrier 32 that holds the front wheel 14 of the vehicle 11. It is arranged near the intermediate wheel 34. The front wheel 14 of the vehicle 11 secures a space S in the recess 32 </ b> A of the tire carrier 32 in order to absorb the tire displacement when rotating around the vehicle locking pin 4.
[0035]
By adopting such a three-axis cart configuration, there are advantages that the vehicle is stable and the grounding condition of the cart can be improved as compared to the two-axis cart configuration. The grounding condition can be improved in conjunction with the installation of the grounding promoting brush on the wheel of the carriage, and the short-circuit sensitivity of the track circuit can be improved.
[0036]
In this way, since the wheels can be attached, it is possible to cope with track circuits and current collection, so that it is possible to develop a trolley bus system (underground section, tramway section).
[0037]
Further, as shown in FIGS. 1 and 3, by providing a snow plow 5 in front of the tire carrier 2 of the carriage 1, the vehicle can be advanced while removing snow on the rail and the tire running path.
[0038]
Note that the tire travel path 22 can be arranged in a track that has already been secured, and there is no need to newly secure a site.
[0039]
In addition, as a vehicle, a bus driven by a prime mover has been described as an example, but application to a trolley bus that supplies power from a rail, other special vehicles, and a connected vehicle is also possible.
[0040]
In the method of the present invention, since the front wheels are guided by the rails and wheels, not only is it easy to lay the traveling plate, but it is also possible to share the railroad and track circuits, so it is possible to deal with ATS and railroad crossing circuits. is there. It is also possible to perform electric driving by adding a current collector.
[0041]
The cart is a simple and lightweight mechanism, and it is easy to attach and detach because it has a brake device attached to the body.
[0042]
In addition, this invention is not limited to the said Example, A various deformation | transformation is possible based on the meaning of this invention, and they are not excluded from the scope of the present invention.
[0043]
【The invention's effect】
As described above in detail, according to the present invention, the following effects can be obtained.
[0044]
(A) While simplifying the trolley | bogie which drive | works a rail, a vehicle can drive | work by driving the rear wheel of a vehicle only by attaching the front wheel to a trolley | bogie.
[0045]
(B) The three-axis cart configuration has the advantage that the vehicle can be stabilized against point interruptions and actions, and the grounding conditions of the cart can be improved compared to the two-axis cart configuration.
[0046]
(C) By providing a snow plow in front of the tire carrier of the bogie, the vehicle can be advanced while removing snow on the rail and the tire travel path.
[0047]
(D) When there is a tendency to reduce the number of railway users in depopulated areas and the new supply of railway vehicles is difficult due to budget constraints, a bus can be used instead of the railway cars. A dual mode vehicle transportation system can be provided, and a flexible and efficient transportation system can be constructed.
[0048]
As described above, since the changeover of the track is short, the time required for direct communication can be shortened, and the ground equipment is also inexpensive.
[0049]
Moreover, since only the traveling plate is placed outside the track, it is easy to secure the wheel flange way in the snowy area.
[0050]
Further, the regular deceleration for running on the track is sufficient for the rear wheels, but the front wheels can also be suddenly decelerated by the action of the vehicle body side brake, thus avoiding danger.
[0051]
In addition, the structure of the carriage is simple, and there is no connection of piping from the vehicle body side, so the attachment / detachment time is short, and no brake or the like due to troubles of these connection parts does not occur.
[0052]
Furthermore, since the rail track circuit equipment can be used almost as it is, it is possible to enter and mix with railway vehicles. Since the front wheels are mounted on the front carriage, the suspension of the front wheels can be utilized in track running, so that the ride comfort is reduced.
[0053]
In addition, the scale of commercial bus remodeling is small compared to previous systems.
[0054]
Any system currently under development can be used for the power source of the bus.
