  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, conceptual diagrams are shown, and detailed structures and the like are not shown. FIG. 1 is a front view of the vehicle 1. The vehicle 1 mainly includes a vehicle body 3 and a carriage 4.

  As shown in FIG. 1, the vehicle body 3 is a portion on which passengers and luggage are placed. The carriage 4 is below the vehicle body 3 and supports the vehicle body 3. The carriage 4 is a traveling device, and mainly includes an axle 5, wheels 7, driving tires 9, a carriage frame 11, and an air spring 13. The carriage frame 11 is a structure attached to the vehicle body 3 via an air spring 13 to support the weight of the vehicle body 3 and distribute the weight of the vehicle body 3 to the wheels 7 and the drive tires 9. 5 position is determined.

  The axle 5 is rotatably attached to the carriage frame 11 via a shaft spring and a shaft box (not shown). The wheel 7 is fixed to the axle 5 and rotates together with the axle 5. Similarly, the driving tire 9 is fixed to the axle 5 and rotates together with the axle 5. The driving tire 9 is installed outside the wheel 7. An iron wheel can be used as the wheel 7. As the driving tire 9, a rubber tire can be used.

  FIG. 2 is a side view of the vehicle 1. As shown in FIG. 2, the carriage 4 is disposed in front of and behind the vehicle body 3 and travels while supporting the vehicle body 3. The carriage 4 is provided with an axle 5. Wheels 7 and driving tires 9 are attached to the axle 5. It should be noted that the carts 4 are not limited to the illustrated example, and at least one pair of the carts 4 may be disposed at the front and rear.

  The wheel 7 and the driving tire 9 do not have to be supported by the same axle 5, but the wheel 7 and the driving tire 9 may be installed on the same axle 5 as shown in FIG. desirable.

  FIG. 3 is a configuration diagram showing a driving device and the like in a state where the vehicle 1 travels on the track 24. The vehicle body 3 includes an engine 15, a gear 19, a steering mechanism 21, and a link mechanism 23. The vehicle body 3 and the carriage 4 include devices such as a brake and a drive mechanism that are not shown. A track 24 for the vehicle 1 to travel is on a roadbed 25 and includes a road bed 27, a sleeper 29, a rail 31, and a tire travel surface 33.

  The engine 15 is connected to the axle 5 via a gear 19 and transmits power to the wheels 7 and the driving tire 9 via the axle 5. When the vehicle 1 travels on the track 24, the wheel 7 travels on the rail 31, and at the same time, the driving tire 9 travels on the tire travel surface 33 located outside the sleeper 29. At this time, the driving tire 9 and the wheel 7 function as driving wheels.

  The engine 15 does not have to be connected to all of the plurality of axles 5 provided on the carriage 4, and may be connected to at least one axle 5. That is, all the wheels 7 and the driving tires 9 do not have to be driven by the power from the engine 15.

  As shown in FIG. 3, the height of the ground contact surface of the wheel 7 is located above the height of the ground contact surface of the driving tire 9. For this reason, when traveling on the track 24, the driving tire 9 travels on the tire traveling surface 33, and at the same time, the wheel 7 can travel on the rail 31 positioned above the tire traveling surface 33.

  In addition, the vehicle 1 includes a steering mechanism 21. The steering mechanism 21 is connected to the carriage 4 via the link mechanism 23 and steers the driving tire 9. When the vehicle 1 travels on the track 24, the steering mechanism 21 is disconnected from the link mechanism 23. At this time, the carriage 4 can be rotated in the horizontal direction with respect to the vehicle body 3. Therefore, the carriage 4 rotates according to the rail 31, and the vehicle 1 can travel along the track 24.

  As shown in FIG. 3, the road bed 27 is for holding and fixing a sleeper 29 and generally uses ballast or the like. The sleeper 29 is installed on the road bed 27. The sleeper 29 supports the rail 31, keeps the distance between the rails 31 constant, and distributes the load of the vehicle 1 to the road bed 27. The rail 31 is fixed to the sleeper 29. The wheel 7 travels on the rail 31.

  At this time, the rail 31 functions as a track circuit. That is, when the vehicle 1 travels on the track 24, it detects the presence or absence of other trains and vehicles via the wheels 7 that are in contact with the rails 31, and receives information for control. Therefore, the vehicle 1 can be safely operated even in a route section where other trains and vehicles are simultaneously operated.

  The tire running surface 33 is obtained by performing scattering prevention processing on a part of the road bed 27 outside the sleeper 29. The driving tire 9 travels on the tire travel surface 33. Examples of the scattering prevention process for the road bed 27 include pavement using asphalt, concrete, or a method of fixing a panel or the like on the road bed.

  FIG. 4 is a perspective view of the vehicle 1 traveling on the track 24 as seen from above. As shown in FIG. 4, the drive tire 9 is installed outside the wheel 7, and a space is formed in the axial direction of the axle 5 between the wheel 7 and the drive tire 9. In other words, the wheel 7 and the driving tire 9 are spaced apart from each other on the same axle 5. This space is located between the rail 31 and the tire running surface 33 when the vehicle 1 travels on the track 24. As a result, the track structure is such that an existing track maintenance machine such as a multiple tie tamper can be used.

  FIG. 5 is a configuration diagram showing a drive device and the like in a state where the vehicle 1 travels on the road 35. The vehicle 1 is equipped with an engine 15. The engine 15 is connected to the axle 5 via a gear 19 and transmits power to the driving tire 9. When the vehicle 1 travels on the road 35, the driving tire 9 travels on the road 35, and the driving tire 9 functions as a driving wheel.

  As shown in FIG. 5, the height of the ground contact surface of the wheel 7 is located above the height of the ground contact surface of the driving tire 9. For this reason, when traveling on the road 35, the driving tire 9 travels on the tire traveling surface 33, but the wheel 7 does not contact the road 35.

  As described above, the vehicle 1 includes the steering mechanism 21. The steering mechanism 21 is connected to the carriage 4 via the link mechanism 23. When the vehicle 1 travels on the road 35, the steering mechanism 21 is connected to the link mechanism 23. Therefore, the driving tire 9 can be steered.

  The road 35 on which the vehicle 1 travels is a travel path provided for vehicles and the like to pass, and generally, the travel surface is paved with asphalt or the like.

  As described above, according to the vehicle 1, the track 24, and the road 35 of the present embodiment, when the vehicle 1 travels on the track 24, the vehicle 1 travels using the wheels 7 and the driving tire 9 at the same time. In addition, when driving on the road 35, the driving tire 9 is used. Thus, the vehicle 1 can travel on the track 24 and the road 35. Therefore, a traveling system (operation method) of the vehicle 1 that can travel on the track 24 and the road 35 can be obtained.

  Further, when traveling on the road 35, the wheel 7 does not contact the road 35, so that the wheel 7 does not interfere with the road 35 when traveling on the road 35. That is, when traveling on the track 24 and traveling on the road 35, the travel mode is achieved by simply connecting and disconnecting the steering mechanism 21 without requiring a complicated mechanism such as the lifting and lowering operation of the wheels 7 and the driving tire 9. Can be switched. Therefore, vehicle improvement and vehicle operation become very easy.

  Further, since the wheel 7 and the driving tire 9 are installed on the same axle 5, the structure is simple and the vehicle 1 can be reduced in weight.

  In addition, the conventional dual mode vehicle has a problem that rubber tires are severely worn because rubber tires run on iron rails during track running. However, according to the track of this embodiment, asphalt is provided on the tire running surface 33. By performing pavement suitable for running rubber tires and the like, it is possible to reduce tire wear compared to running on an iron rail. That is, the track 24 can travel the vehicle 1 only by performing a roadbed scattering prevention process on a general railway track, and the existing facilities can be easily improved and can be constructed at low cost.

  Further, since the vehicle 1 travels using both the wheels 7 and the driving tires 9 when traveling on the track 24, the braking distance is shortened and the operation density is increased as compared with a railway vehicle traveling only by wheels. it can. Furthermore, if a rubber tire is used for the driving tire 9, the acceleration, the climbing ability, and the low noise performance can be improved by using friction between the driving tire 9 and the tire running surface 33 as compared with a railway vehicle that runs only by wheels. Is obtained.

  Furthermore, by providing the wheel 7 and the driving tire 9 with a space in the axial direction, a track structure is provided in which an existing track maintenance machine can be used, and track maintenance can be easily performed.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs.
