Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic levitation type traveling body and a method for stabilizing the traveling thereof, and particularly to a traveling body suitable for a magnetic levitation train in which the repulsive force of an inner magnet of a railway vehicle is used to levitate the vehicle body. Concerning driving stability method.

[0002]

2. Description of the Related Art In a magnetic levitation train in which a vehicle body is levitated by utilizing the repulsive force of a magnet, electromagnetic coils that receive a levitation force and a propulsion guide force are attached to both sides of the vehicle body. Since the levitation and propulsion guide coils are discretely arranged on the ground guideway, the levitation force and the propulsion guide force received by the vehicle body are oscillating. Especially, rolling of the car body (yawing)
As for, no such measures have been taken.

As a means for maintaining stability during running of a magnetic levitation train, there is an example described in JP-A-54-136018.
In the configuration of this example, a horizontal wing is attached to the head portion of the levitation vehicle, and the steering angle of the wing is adjusted according to the traveling speed to control the stable traveling posture of the vehicle.

Furthermore, as a measure to prevent rolling of a magnetically levitated train,
There is an example in which a symmetrical blade is placed on the top of the vehicle body, and this blade is rotated to exert a horizontal lateral force (aerodynamic force) in the direction opposite to the rolling direction, which serves as a vibration suppression force. 61-159803
(See the official gazette).

There is also a proposal of a structure similar to an aircraft in which the body is levitated by the lift of the wing instead of using the magnetic force (Aero-tr
ain).

[0006]

However, in the prior art in which the horizontal blades are provided, even if the rudder angle of the horizontal blades is adjusted, it will stabilize the vertical movement (pitching) of the vehicle body. There was a problem that the shaking had no effect.

Further, mounting the wings at a high position on the vehicle body is easily affected by side winds and gusts, and the presence of the wings may hinder the running stability. Moreover, the wing body that overhangs in the tunnel, at the station, or at the base will be an obstacle to running or construction.

In the Aero-train, the wing body is limited to a horizontal body, and this wing body has only a function for generating a lift force, and cannot produce any rollback suppressing effect.

A first object of the present invention is to provide a traveling stabilizing device which is also effective for yawing the vehicle body.

A second object of the present invention is to provide a device for ensuring the running stability of each connected vehicle.

A third object of the present invention is to provide a traveling stabilizer which is not easily affected by side winds and gusts and which does not disturb the inside of a tunnel or a station.

[0012]

According to the present invention, a current is passed through a coil mounted on a vehicle body to generate a magnetic field, and a repulsive force is generated between the coil and a coil installed on a guideway (orbit). The present invention relates to a magnetic levitation type traveling body that levitates a vehicle body, and has the following features.

(1) A device for rectifying the flow of air on the outer surface of the vehicle body is provided at the upper end of the side wall of the guideway (height.
Mount on a lower body surface.

(2) Forming a convex portion and / or a concave portion unrelated to the traveling of the traveling body on the outer surface of the vehicle body and at a position lower than the upper end of the side wall of the guideway.

(3) A protrusion is formed on the outer surface of the vehicle body and at a position lower than the upper end of the side wall of the guideway, and a groove is formed inside the guideway so as to fit the protrusion with a gap.

(4) A device for rectifying the air flow on the outer surface of the vehicle body is formed on the outer surface of the vehicle body or both on the outer surface of the vehicle body and on the inside of the guideway facing the vehicle body. Control by communication means.

(5) Each of the rectifying devices or the convex portions and / or the concave portions has a function of aligning the air flow on the outer surface of the vehicle body in one direction.

(6) The respective rectifying devices or the convex portions and / or concave portions do not directly contribute to (participate in) the running stability.

(7) The recess is a groove, particularly preferably a plurality of grooves.

(8) A hangar is provided in the vehicle body so that each of the rectifying devices or the convex portions and / or the concave portions can be stored in the vehicle body.

(9) The convex portion is arranged substantially vertically below the vehicle body. More desirably, a plurality of blades may be arranged, a rectifying device may be installed for each vehicle body, a mechanism that can arbitrarily change the air flow on the outer surface of the vehicle body, and the like.

[0022]

According to the present invention, the rectifying device operates in the air stagnating inside the guideway. While the traveling body is traveling, the rectifying device receives a force from the air flowing on the outer surface of the vehicle body, and acts so that the posture of the vehicle body is changed.

A fluid force generated in a convex portion such as a wing or a regular air vortex generated in a concave portion acts so as to apply a force in a certain direction to the vehicle body.

The fluid force applied to the vehicle body via the convex portion or the rectifying device can be applied to each connected vehicle. Further, the force applied to the traveling body can be changed by changing the rudder angle of the wing.

Convex portion or straightening device (including part) in the hangar
If it can be stored, it acts so that it does not receive any fluid force when traveling in a curve or when entering a tunnel.

The operation of the rectifier may be uncontrolled via external communication means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) A first embodiment of the present invention will be described with reference to FIGS.

A superconducting magnet 2 is attached to a front portion and a rear portion of each vehicle via a carriage 3 in a vehicle body 1 in which a plurality of vehicles are connected. The guideway 4 is provided with a levitation coil 5, a propulsion guide coil 5, a propulsion guide coil 6, and a power transmission cable 7 connecting them.

Wings 8 are attached to the front and rear of the vehicle body 1 vertically and horizontally. The wings 8a on the upper surface are low enough to allow running in a tunnel. Also, the lower wing 8b
Is a height that does not contact the bottom surface of the guideway 4 when the wheels are traveling at low speed. The wings 8c on the left and right sides have a width that does not contact the side wall of the guideway 4. The wing 8 is also attached to the intermediate vehicle. When the vehicle runs, a force is applied to the wing 8 by air in a direction perpendicular to the traveling direction of the vehicle, and a force is generated in a direction to stop the sway of the wing 8. This force is applied to the vehicle body 1 as it is to prevent the vehicle body from shaking during traveling.

(Second Embodiment) A second embodiment of the present invention will be described with reference to FIG.

As in the previous case, the blades are used as the rectifying device, but in this example, the blades 9 are discretely arranged around the cross section of the vehicle body 1. By doing so, the force applied to the vehicle body 1 can be dispersed, the force shared by each blade 9 is reduced, and the effect is that the shape of each blade 9 can be reduced.

(Third Embodiment) A third embodiment of the present invention will be described with reference to FIGS.

The present embodiment is an example in which the upper portion of the blade 9 proposed in the second embodiment is covered with a panel 10. The blades 11 may be continuously attached to the inside of the panel 10 along the traveling direction of the simple substance 1, or may be discontinuous on the way.

The air sucked in the front part of the vehicle body 1 is surrounded by the panel 10 and the wing 11, and goes out from the rear part through the duct part. According to the present embodiment, even if a cross wind hits the vehicle body, it does not hit the wing 11 and the posture is not disturbed by the cross wind. Another possible method is to use this duct to send air into the vehicle body 1 and again to inject air from the jet outlets on the side surface of the vehicle body toward the guideway 4, and to prevent the vehicle body 1 from rolling laterally by its reaction force.

(Fourth Embodiment) A fourth embodiment of the present invention will be described with reference to FIGS. 6, 7 and 8.

In FIG. 6, the wing 12 which functions as a rectifier is continuous from the front part to the rear part of each vehicle body 1. By doing so, in addition to the effect of the fluid force acting on the wing, the effect of improving the rigidity of the vehicle body 1 is produced.

FIG. 7 is a bottom view of the vehicle body 1. In this example, the blades 13 are arranged in different stages. By doing so, it is possible to make them less susceptible to the influence of the turbulent flow generated behind each blade.

The blades do not always have to be placed parallel to the traveling direction, and may be arranged at an angle like the blades 14 as shown in FIG. With this arrangement, the fluid force acting on the wing 14 is further generated in the direction of the center line of the vehicle body 1, and the rolling can be prevented. Further, the same effect can be expected with a blade having a taper like the blade 15.

(Fifth Embodiment) A fifth embodiment of the present invention will be described with reference to FIG.

Wings 16 (16a, 16b) are attached to the side surface and the lower surface of the outer surface of the vehicle body 1. The wings are mounted at a position lower than the height of the side wall of the guideway 4. By doing so, the posture of the vehicle body 1 can be kept stable without being affected by gusts or side winds.

(Sixth Embodiment) A sixth embodiment of the present invention will be described with reference to FIG.

In this example, the shape of the wing 17 is changed for each vehicle in the connected vehicles 1. This is an example in which the height of the wing 17 is increased as the vehicle 18 in the rear portion becomes closer. This produces the effect of reducing the air resistance of the traveling wing and the effect of not receiving the turbulent flow generated at the rear end of the wing attached to the front vehicle 19.

(Seventh Embodiment) A seventh embodiment of the present invention will be described with reference to FIGS. 11, 12 and 13.

A plurality of recesses 20 are provided on the outer surface of the vehicle body 1. The concave portion is manufactured by making a recess by press working when manufacturing the vehicle body 1 made of, for example, aluminum. The size is arbitrary, and various shapes such as circular and rectangular can be considered. Due to the recess 20, the rigidity of the body is improved, and the turbulent flow generated in the recess during traveling reduces the air resistance and enhances the straight running stability.

FIG. 12 shows an example in which a recess is provided in the guideway 4. A plurality of straightening vanes 21 are provided on the vehicle body 1 side,
The guideway 4 is provided with a groove 22 through which the blade can freely move. During traveling, the flow straightening vanes 21 pass through the air stagnated in the grooves 22, and the fluid force at that time causes the vehicle body 1 to go straight. This example has the advantage that the height of the blade can be increased. Also, in an emergency, this wing serves as a roll stopper.

FIG. 13 shows an example in which the groove 23 is provided on the vehicle body 1 side. The groove 23 may be continuous from the front part to the rear part of the vehicle body 1 or may be discretely cut in the middle. The direction of the groove may be the traveling direction or may be angled. During traveling, air enters the groove 23 and applies a force to the inner surface of the groove 23. As a result, the vehicle body 1 can travel while maintaining straightness even if it receives a force that causes the vehicle body to roll laterally due to a slight disturbance.

Since it is a groove, it is not affected by cross wind. Further, since the groove is formed on the outer plate of the vehicle body 1 by pressing or the like, there is an advantage that the bending rigidity of the body is increased.

(Eighth Embodiment) An eighth embodiment of the present invention will be described with reference to FIGS. 14, 15, 16, 17, 17, and 19.

The operation of this example will be described with reference to FIG. The sensor 28 constantly measures the distance δ from the guideway 4 during traveling. The sensor 28 also measures the acceleration G of the vehicle body 1 at the same time. If the distance δ from the guideway becomes small for some reason during traveling, and the distance from the side wall becomes too close, the calculator 29 causes the vertical blade 25 to move until the distance falls within the allowable range.
Adjust the rudder angle of. At this time, the effect of the acceleration G is also calculated by the calculator 2.
9 Incorporated into the internal calculation, by modifying the rudder angle,
The steering angle correction amount is determined so that the vehicle body does not vibrate.

When the vehicle body 1 is tilted as shown in FIG. 17, the unit 24 at the front of the vehicle body adjusts the steering angle of the vertical wing 25 so as to move the vehicle body downward in the drawing and the rear unit 24 moves the vehicle body upward. To do. By attaching this unit to each vehicle, the posture of each vehicle can be changed independently.

FIG. 18 shows an example of suppressing vertical movement (pitching) of the vehicle body 1 by using the horizontal wing 30 of the unit 24. It is assumed that the vehicle body 1 is in a posture of raising the front part and lowering the rear part while traveling. At this time, the sensor inputs the distance from the floor surface of the guideway and the vertical acceleration into the calculator 29 to determine the correction amount of the steering angle. In the example of the drawing, the rudder angle of the horizontal wing 30 is adjusted by the servo motor 27, and each wing moves so as to lower the front part and raise the rear part.

FIG. 19 shows an example in which the vehicle body 1 is rolling. In this case, the horizontal blades 30 may be moved in opposite phases on the left and right, and the steering angle is adjusted so that the right blade in the figure raises the vehicle body and the left blade lowers it.

In the example using these units 24, the blades operate in a portion of the guideway which is not affected by gusts or crosswinds, so that stable control can be performed.
