Description

[Detailed Description of the Invention] The present invention relates to a vehicle body support device for a magnetically levitated vehicle.

The bogie of a magnetically levitated vehicle driven by a superconducting magnet-induced repulsion type linear synchronous motor has the following differences from a bogie of a general railway vehicle. That is, since a general bogie has its body supported on two bogies, there is no particular problem even if the dimensions between the bogies change when traveling on a curved section. however,
In the above-mentioned magnetic levitation vehicle, superconducting magnets are arranged along the entire length of the vehicle, and a synchronous motor cannot be constructed unless the distance between each pole is maintained at the correct pitch.

Next, it is possible to support the car body by constructing a bogie for one magnetically levitated vehicle with two bogies, front and rear, like a general vehicle, but since the distance between the supports is large, it is necessary to increase the strength of the car body, and the weight of the vehicle is This is disadvantageous in terms of promoting

The object of the present invention is to provide a vehicle body support device for a magnetically levitated vehicle that can operate through curves without problems, and that can simplify and reduce the weight of the vehicle body itself and the structure between the vehicle body and the bogie. .

In this invention, the bogie is composed of three bogies: an intermediate bogie, the front and rear bogies, and each bogie is connected by a coupler that can rotate vertically and horizontally. A superconducting magnet is installed, and multiple superconducting magnets are also installed on both sides of the intermediate bogie, and the car body is supported via air springs with low rigidity on the left and right sides on each bogie. are connected by anchors placed on both sides of the intermediate bogie in the longitudinal direction, and the weight of the vehicle is supported by the entire bogie without significantly changing the distance between the superconducting magnets when passing through a curve. , and allowing horizontal displacement between the car body and the bogie by the air spring,
Furthermore, the longitudinal force between the vehicle body and the bogie is transmitted by the above-mentioned anchor with a simple structure.

Hereinafter, one embodiment of the present invention shown in the drawings will be described in detail. 1 is a car body, 2A, 2B, and 2C are carts, and the same number of superconducting magnets 3 are attached to both sides of the carts 2A and 2C, and the cart 2B is an intermediate cart, and the number of superconducting magnets 3 is larger than that of the cart 2A. installed. Each trolley 2A, 2B,
2C is provided with auxiliary support devices 4A, 4B, 4C and auxiliary guide devices 5A, 5B, 5C,
Moreover, between each trolley 2A, 2B and 2C, the central part 1
The points are connected by a coupler 6 that can rotate vertically and horizontally to form a bogie of one vehicle. Incidentally, couplers 7 are provided at the ends of the carts 2A and 2C to connect the carts to each other. 10 is a guideway.

The vehicle body 1 is supported between the bogies 2A, 2B, and 2C by interposing air springs 8A, 8B, and 8C as secondary support devices, which have low lateral rigidity, that is, allow displacement in the width direction of the vehicle body. Further, the longitudinal force between the car body 1 and the bogie is transmitted by connecting one end to the car body 1 allowing vertical displacement, and connecting the other end to the bogie 2B allowing vertical displacement, and It is configured to transmit by anchors 9 arranged in parallel on both sides.

By supporting the vehicle body 1 with such a configuration, when passing through a curve, the bogies 2A, 2B, and 2C are bent along the guideway 10 at each connecting point coupler 6, as shown in FIG. pass in state. At this time, the vehicle body 1 can be operated without any problem in a posture parallel to the bogie 2B as shown by the double dotted line in FIG. In other words, the horizontal displacement of the bogies 2A and 2C with respect to the car body 1 is not affected because the anchors 9 arranged on both sides of the bogie 2B have a firmness as described above, and the bogies 2A and 2C are moved evenly. Relative movement can be performed. In addition, in the curve passing state, relative left-right displacement between the car body 1 and the bogies 2A, 2B, and 2C causes unnecessary reaction force because the air springs 8A, 8B, and 8C have low left-right rigidity. The relative movement is not restricted.

As explained above, according to the present invention, since the load movement is supported by the entire front and rear direction of the vehicle body 1, it is not necessary to improve the strength of the vehicle body 1 and the weight can be reduced. Since it is supported only by air springs and the longitudinal force can be transmitted by the anchor between the intermediate bogie and the car body, the structure between the car body and the car body can be simplified and the weight can be reduced. In addition, by dividing the cart into three carts and connecting them with a coupler, and supporting the cart through air springs with low left and right stiffness, the entire cart can bend and follow the guideway well, making it easier to pass through curves. It can be operated without any problems.
