ている。 A vehicle body 1 is supported by a truck 2 via an air spring 3. It is connected to a truck 2 in the front-back direction by an anchor 4 having a shock absorbing device, and each truck 2 is connected by a connecting link 5 between the trucks. FIG. 2 is a plan view showing the truck 2 in detail, and FIG. 3 is a side view thereof. Although many necessary structures are attached to an actual truck, only the important elements are shown. The bogie frame 2 has air springs 3, 3 on the left and right sides of the upper center surface. The bogie frame 2 has side beams arranged on the left and right sides, and four superconducting magnets 6 are arranged on the outside of the side beams. This is an example of a superconducting electromagnet for a U-shaped track. Each superconducting electromagnet houses one racetrack superconducting coil, and helium is used to cool this coil as needed. A reliquefaction machine is also included. At the front and rear ends of the underframe, connecting links 5,
5 is arranged and connected to other carts. The rubber tires 7 for ground running are designed to travel by receiving the load of the vehicle bogie since the levitation force does not act on the superconducting electromagnet in a low speed range, and aircraft tires or the like are used. Each of these four rubber tires 7 has a support device 8, and when the levitation force is obtained due to high-speed running, the tire is raised by an oleo device using an internal upper and lower cylinder to avoid contact with the ground. Even when the bogie is pitched and moved up and down, the tires are kept from rubbing against the road surface at high speed and becoming worn out. However, if the superconducting electromagnet malfunctions and quenches during high-speed running, and if the levitation force is lost and the vehicle lands, it is considered that the vehicle will land sliding in the sliding shoe 12. Similarly, each of the four side guide wheels 10 has a retraction device 11, and when the floating becomes stable at high speed, the retraction device is activated to release the guide wheel from the guide wall, but abnormal lateral displacement is prevented. In order to prevent abnormal displacement, the guide wheels themselves are made of hard wheels or have sliding surfaces.

るものである。(Problem to be Solved by the Invention) The above-mentioned superconducting magnetic levitation vehicle uses a strong magnetic flux of a superconducting electromagnet to obtain propulsion power in synchronization with the primary motor of a linear synchronous motor installed on the ground side. The vehicle generates an induced current by moving on a loop coil placed on the vehicle, and the induced magnetic flux is repelled by the superconducting magnet on the vehicle, causing the vehicle to levitate.

る傾向がある。 When considering train organization using such magnetically levitated vehicles, the following problems arise. A characteristic of linear synchronous motors is that if the pitches on the vehicle and on the ground are not precisely aligned, a strong forward force or braking force will be applied, making it impossible for the vehicle to run smoothly. For this reason, the superconducting magnetically levitated vehicle currently being planned connects the bogies with superconducting electromagnets to each other using a fairly rigid coupler, and on top of that, a slightly soft anchor is used to move the body of each vehicle in the longitudinal direction. They are connected and supported vertically and horizontally using air springs. In this way, the vehicle body will not be subjected to front and rear buffer shocks, and will have a structure similar to that of an aircraft fuselage, which can withstand the load of passengers and the pressure differences caused by high-speed travel in tunnels, etc., making it possible to create an extremely light structure. However, the trolley is equipped with powerful superconducting electromagnets, helium freezing and liquefaction machine running wheels,
In addition to guide wheels, skid devices for landing during high-speed running, etc., coupling devices between bogies must also be installed, which tends to increase the weight compared to the vehicle body.

する手段が無く非常に困つた状態となつている。 If we consider the appearance of a running vehicle with such weight distribution from the perspective of vehicle vibration theory, the vibrations generated by running the vehicle are caused by all of the irregularities in the rails and electromagnetic vibrations that are applied to the bogie and via the springs. is transmitted to the vehicle body. Here, if the car body is made strong like a general railway car and a lot of equipment is loaded, the car body is heavy and the bogie is light, so even if the bogie generates some vibration, the pillow spring between the car body and bogie By inserting a damper in the section, it is possible to suppress the vibration of the truck to such an extent that it hardly becomes a problem. However, in the case of a superconducting magnetic levitation vehicle, unfortunately all the heavy objects are concentrated on the bogie, and the vehicle body is abnormally light, so no matter how many dampers are inserted at the pillow springs, it will not be effective as long as the vehicle body is light. The superconducting magnetic levitation vehicle is in a very difficult situation because it cannot generate damping force and there is no means to ensure the ride comfort of the superconducting magnetically levitated vehicle.

The object of the present invention is to provide a superconducting magnetic levitation vehicle having the following characteristics.

力を発生する。(Example) A description will be given below based on the drawings. First of all,
Referring to FIG. 5, an embodiment will be described in which a dynamic damper is constructed using a ground running tire device 7A. The pneumatic tire 7 is rotatably attached to the shaft 14 at the tip of a piston body 13 bundled with the oleo 8 of the tire support device 8A using a rotation prevention device 15. This oleo 8 is a support shaft and is attached to the truck by a shaft 16 fixed to its upper end. Links 21 and 22 are attached to the middle portion of the oleo 8 and are connected to a fixed end 23 of the truck. A hydraulic cylinder 24 and a piston 25 are connected to this link 22, and the other end 26 is attached to a truck. Furthermore, the tip 18 of arm 17 that came out from Oreo 8
A tension spring 19 is disposed between the support point 20 and the support point 20 on the truck side, and pulls the tip 18 of the arm 17 upward. Here, when the piston 25 is in the extended state, the link 21,
22 is straight and locked so that it cannot move even if a compressive or tensile force is applied. At this time, since the tip 18 is on the opposite side of the links 21 and 22 with respect to the rotation axis 16 of the oleo 8, the oleo 8 applies a rotational force to rotate counterclockwise in FIG. 4.
Here, when the piston 25 is retracted, the links 22 and 21
The oleo 8 rotates clockwise until it becomes almost horizontal. At this time, when the arm 17 also rotates clockwise, the tip 18 will move between the fulcrum 20 and the shaft 16.
In this relationship, the spring 19 passes through the hole point and generates a force in the clockwise direction that can support the entire weight including the oleo 8.

It is devised so that it rotates around the axis perpendicular to the Oreo car body and has a retracting effect.

C, the throttle 31 connects to the hydraulic source 2 via the electromagnetic switching valve 28;
7 and the oil drain port 32. Hydraulic solenoid switching valve 2
8 has three positions, 29A, 29B, and 29C. At 29A, high pressure oil acts on the upper chamber of the piston 25A, the piston 25 extends, and the pneumatic tire 7E
hold in the exit position. Next, at 29B, high pressure oil acts on the lower amount of piston 25A, causing piston 25
compresses to hold the pneumatic tire 7E in the folded position.
Next, at 29C, the pipes 30A and 30B communicate through the throttle 31 and the pipe 30C, so the upper and lower chambers of the piston 25A communicate with each other, and the piston 25A freely moves up and down with a certain throttle effect. things become possible.

を誘起せしめる事が出来る。 Next, the effect will be explained. The pneumatic tire, oleo, and other parts are completely locked down and no parts can move when the pneumatic tire is in the lowered position, so that it appears completely fixed to the trolley. However, when the truck travels and obtains levitation force, and the pneumatic tires no longer bear the load, the entire pneumatic tire system is pulled up horizontally to a nearly horizontal position centering on the top of the oleo, and the spring 19 absorbs its weight. At the point where the piston 25A can be supported, the upper and lower chambers of the piston 25A communicate with each other, and the entire pneumatic tire device is attached to the shaft 1 while being suspended by the spring 19.
You will be able to swing around 6. At this time, the weight of the pneumatic tire device is not added to the weight of the truck, and if the inertia weight around the shaft 16 of the pneumatic tire device and the spring constant of the spring 19 are properly taken, the natural vibration is approximately equal to the vibration excitation frequency of the truck. It becomes possible to act as a spring-suspended mass having . This acts as a vibration absorbing device, which is generally discussed in mechanical vibration theory, and even if the frequency is off, the vertical movement of the piston 25A causes the links 21 and 22 to move due to the vibration of the oleo device 8E, causing oil to flow through the throttle 31. It can flow through the area and induce a damping effect.

In other words, according to the superconducting magnetically levitated vehicle structure of the present invention, the pneumatic tire device is firmly fixed to the bogie while the tires are running, and when the pneumatic tire device moves to levitated running, the pneumatic tire device has a sprung mass in addition to the insufficient sprung vehicle weight. This makes it possible to effectively act on vibration damping. However, the mass of a single pneumatic tire mechanism is not very large, but since there are many of them, it becomes a considerable value when compared to the total mass of the bogie, and it has a sufficiently effective damping effect. Instead of storing pneumatic tires using a mechanism that raises and lowers them in the past, the pneumatic tires are stored using links, so the increase in structural weight is so small that it can be ignored, and there is almost no change in vehicle weight. It is an extremely effective means to be able to create a vibrating mass for damping.
