Description

FIELD OF THE INVENTION The present invention relates to a track vehicle, and more particularly to a vehicle capable of bending along a curve of a track. More specifically, the present invention relates to a suspension articulated vehicle in which a vehicle body is suspended and supported on a track via a carriage.

2. Description of the Related Art Orbital transportation devices constructed in recent years often employ an elevated structure so as not to hinder road traffic. Since the construction cost of this elevated structure is higher than that of the surface structure, various lightweight and inexpensive structures have been proposed to solve the problem. For example, Japanese Patent Publication No. 58-5528 discloses a track structure in which a supporting cable is attached in a catenary shape between steel towers arranged at intervals, and a rail is supported on the supporting cable via a hanger. The vehicle is thus suspended on the rail supported by the support cable and travels along the rail.

This cable suspension method can be expected to have the advantage that the track structure is light and inexpensive, but since the track structure is largely bent by the weight of the vehicle, a vehicle that can adapt to the bending and run smoothly is required. As a vehicle that seems to be suitable for this purpose,
It was used to transport personnel at the 1978 International Exposition in Mannheim, West Germany. The vehicle in the transportation system of Mannheim has a plurality of vehicle bodies arranged in a line, which are pin-coupled to each other at their roofs to form a refractable vehicle. One dolly is provided for each car body,
Each trolley has a pair of running wheels arranged at intervals on the left and right, through which the vehicle body is suspended and supported by the track structure. The running wheels have a flange, and this flange serves as a guide. Therefore, the truck does not have a guide wheel.

In this vehicle body structure, the roof portion is provided with the connection strength of the vehicle body, and a bogie frame having a sufficient strength for suspending and supporting the vehicle body is arranged between the vehicle body and the track. Therefore, in this vehicle structure, the two strength members of the vehicle body roof portion and the bogie frame are arranged close to each other, which is disadvantageous for weight reduction of the vehicle.

Further, when this vehicle is used for a cable track as disclosed in the above-mentioned patent publication, the cable track inevitably undergoes a large deflection due to the weight of the vehicle during use, and therefore the vehicle is in a horizontal plane. In addition, it must be possible to refract in the vertical plane. In this case, the smaller the resistance to refraction in the horizontal plane, the better. However, if the resistance to refraction in the vertical plane is too small, each vehicle body is oriented in any direction in the vertical plane, and a vehicle composed of a series of multiple vehicle bodies. Becomes zigzag, which is not preferable. That is, the trolley
Since it is supported on the track by one running wheel in the front-rear direction, there is no constraint on the movement in the refraction direction in the vertical plane, and refraction occurs in an uncontrolled state. If the resistance to refraction in the vertical plane is too large, the entire vehicle becomes rod-shaped and cannot follow the curve of the track.

Further, when the vehicle is guided only by the flanges of the wheels in a vehicle structure having only two right and left wheels in one vehicle body, the load on the wheel flanges becomes excessive and the life of the wheels is significantly reduced.

Problems to be Solved by the Invention The present invention solves the above-mentioned problems in conventional refractable vehicles. In other words, it is possible to flexibly bend along the vertical and horizontal curves of the track, has no structurally irrational points, is lightweight and inexpensive, and makes the vehicle guide stable. It is an object of the present invention to provide a vehicle that has a long wheel life and is capable of refracting while traveling stably.

Means for Solving the Problems In order to solve the above problems, a refracting vehicle according to the present invention is configured such that bogies each supporting one vehicle body are arranged side by side in the front-rear direction, and the bogies can be refracted from each other. Pin it like this. Further, among these plurality of carriages, four guide wheels are provided for both ends and, at least, for every other one. Then, the adjacent vehicle bodies are elastically coupled to each other at the lateral center of the bottom portion.

That is, in the refractable vehicle according to the present invention, the traveling wheels that roll on the upper surface of the traveling road are arranged in the center of the longitudinal direction of the bogie, and a plurality of bogies that suspend and support the vehicle body are arranged in the front-rear direction. The trolleys are pin-coupled to each other so that they can be bent, and four guide wheels are provided on each of the front and rear trolleys and at least one trolley in the front-rear direction, and each trolley has one guide wheel. It is characterized in that the vehicle bodies are suspended and supported, and the adjacent vehicle bodies are elastically coupled to each other at the lower center of the vehicle body in the vehicle width direction.

Operation According to the above-mentioned configuration of the present invention, since the connection between the vehicle bodies is performed between the bogies, the vehicle body roof portion does not need the structural strength necessary to bear the force generated by the connection between the vehicle bodies. Therefore, the structure of the vehicle body can be made lightweight and inexpensive. Also,
Since the trolley has the necessary guide wheels,
Since the traveling wheels do not have a burden for guiding and all the carriages bend on curved roads, each carriage faces the tangential direction with respect to the curve, and the traveling wheels provided at the longitudinal center of the carriage are Since it faces the traveling direction of a curved road, no side slip occurs. Lifespan is increased. Furthermore, the adjacent car bodies are
Since it is elastically coupled and its coupling position is the center of the vehicle width direction in the lower part of the vehicle body, it does not cause resistance to refraction in the horizontal plane, and it is appropriate for refraction in the vertical plane. Can give resistance. Even if not all the trucks are provided with the guide wheels, if every other truck is provided with the guide wheels, it is possible to accurately travel along the curved road. However, guide wheels are always required for the bogies on both ends.

Embodiment First, referring to FIG. 1 to FIG.
One vehicle, which is composed of one bogie and nine car bodies, is suspended and supported. The vehicle has a configuration in which guided vehicles 7a and general vehicles 7b are alternately arranged one by one. That is, the guided carriages 7a are arranged at both ends of the vehicle, and the general carriages 7b and the guided carriages 7a are alternately arranged toward the inner side thereof. Each trolley includes a vertical member 8a that penetrates the center in the front-rear direction and the vertical member 8a.
8a has a pair of vertical members 8b arranged on both sides, and a horizontal member 8c whose both ends are connected to the vertical member 8b. A rectangular frame is formed by the members 8b and 8c, and the vertical member 8a is a horizontal member. It is connected to the lateral member 8c at the center of 8c. Each of the vertical members 8b is provided with a wheel support frame 8d at the center in the front-rear direction.

Each carriage has traveling wheels 6 supported by a wheel support frame 8d. Further, the carriages are coupled to each other at the end of the vertical member 8a so that they can be bent in a horizontal plane and a vertical plane. As shown in FIG. 1 and FIG. 2, a coupler 31 is arranged at both end portions so as to project in the front-rear direction. A bumper may be attached instead of the connector at this end.

The guided vehicle 7a has guide wheels 9 arranged at four corners of the frame and supported by the frame. The bogies 7a at both ends support the end car body 14a, and the middle bogie supports the middle car body 14b. An anti-vibration rubber 12 is arranged between each carriage and the vehicle body. Referring to FIG. 4, one traveling rail 10 is arranged on each of the left and right sides, each of which is composed of a steel rail piece having an I-shaped cross section, and a guide rail 11 is attached to a side surface of the rail piece. The reaction rail of the linear motor is used as the lower surface of the rail 10. The left and right rails 10 are connected to each other by a bracket 20, and the bracket 20 is suspended and supported by a cable 22 via a track hanger 21. The running wheel 6 rolls on the upper surface of the rail 10, and the guide wheel 9 rolls on the side surface of the guide rail 11. A coil 32 is arranged on the frame of the truck so as to face the conductive plate 33 of the reaction rail, and coupling portions 31a between the trucks are provided at both ends of the truck frame.

Referring to FIG. 2, each of the vehicle bodies 14a and 14b is provided with a pillar 17 extending vertically downward from the vibration isolating rubber 12, and the lower end of the pillar 17 is connected to a floor frame 16 of the vehicle body. Therefore, the weight of the vehicle body is transmitted from the floor frame 16 to the vibration damping rubber 12 via the pillars 17, and is transmitted from the vibration damping rubber 12 to the truck. Adjacent vehicle bodies are elastically connected to each other by a connecting mechanism 13 at the center of the lower part in the vehicle width direction.

FIG. 5 shows the details of the coupling mechanism 13. An end frame 25 is provided at an end of the floor frame 16, and a spring 26 is arranged between the end frames 25 of adjacent vehicles. A rod 27 is arranged so as to penetrate the spring 26 and the frame 25.
Retainers 28 are attached to both ends of the. In each vehicle, a spring 29 is arranged between the retainer 28 and the frame 25. A hood 30 made of an elastic material is arranged between adjacent vehicle bodies, and a bridge 35 is placed on the floor. With the configuration of the coupling mechanism 13, it is possible to reliably prevent the zigzag bending between the vehicle bodies.

Effect As described above, in the present invention, the bogies for supporting the vehicle bodies one by one are arranged side by side in the front-rear direction,
Since these bogies are pin-coupled to each other so that they can be bent, the roof of the vehicle body does not need to have sufficient strength to withstand the vehicle body connection, and the vehicle body can be made lightweight. Also, among the multiple carriages, four guide wheels are provided for both ends and, at least, for every other one, so there is no need to rely on the running wheels to guide the carriage, and all carriages Since it bends on a curved road, each dolly faces the tangential direction to the curve, and the running wheels provided at the longitudinal center of the dolly face the running direction of the curved road, so no side slip occurs and the running wheels The life can be increased. further,
Since the adjacent vehicle bodies are elastically coupled to each other at the center in the vehicle width direction of the lower portion thereof, it is possible to reliably prevent a state in which a series of a plurality of vehicle bodies is bent in a zigzag direction in the vertical direction.

Further, the configuration in which the traveling wheels are arranged at the center in the longitudinal direction of each carriage makes it possible to direct the traveling wheels almost in the tangential direction of the curved track even when the guide wheels are provided on every other carriage. In particular, if the guide wheels of the guided vehicle are located at substantially the same distance from the longitudinal center of the vehicle, the effect is further enhanced.
