Are connected side by side in the traveling direction, and the opposing normal conducting coils are connected to each other by a predetermined wiring method (hereinafter referred to as "null flux wiring"), and the superconducting coil is placed at a position on the vehicle corresponding to the normal conducting coil on the ground side. It is configured by arranging coils.

In the above-mentioned magnetic levitation railway, a superconducting current is passed through a superconducting coil on the vehicle side in advance to form a permanent magnet, and power is transmitted to a normal conducting coil on the ground side by a power transmission device such as a substation, thereby forming a superconducting coil. In addition to generating an attractive magnetic field in the ground-side normal conducting coil located in front of the traveling direction,
A repelling magnetic field is generated in the ground-side normal conducting coil located behind the superconducting coil in the traveling direction, and these magnetic fields are moved in the traveling direction. With this configuration, the superconducting coil on the vehicle side is propelled in the traveling direction by the attractive magnetic force and the repulsive magnetic force of the ground-side normal conductive coil. This is the principle of propulsion of the above-mentioned magnetic levitation railway, and in this case, the ground-side normal conducting coil and the vehicle-side superconducting coil constitute a linear motor.

When the vehicle moves at a high speed in the traveling direction as described above, an induced current is induced in the ground-side normal conducting coil. For this reason, a repelling magnetic force (levitation force) or an attractive magnetic force is generated in the ground-side normal conducting coil to which the vehicle-side superconducting coil is approaching, and the vehicle-side superconducting coil is supported at a predetermined position above the ground-side normal conducting coil. A force is generated.
This is the levitation principle of the magnetic levitation railway described above.

The ground-side normal conducting coils facing each other on the left and right sides in the traveling direction are connected by a predetermined connection method. Therefore, when the vehicle is biased to one of the left and right vertical walls, a repulsive magnetic force is generated in the ground-side normal conducting coil on the biased side, and the vehicle-side superconducting coil is pushed back in the direction opposite to the biasing direction, and the opposite side. Attraction magnetism is generated in the ground-side normal conducting coil, and the vehicle-side superconducting coil is pulled in the direction opposite to the bias direction. As a result, control is performed such that the center of the vehicle is always near the center of the guideway. This is the guiding principle of the above-mentioned magnetic levitation railway.

The magnetic field had leaked out.

Further, in the above-mentioned conventional magnetic levitation railway, if one of the superconducting coils on the vehicle side is broken and becomes a quench state, the balance between the left and right guiding forces is greatly disturbed, and it becomes difficult to guide the vehicle. There was a fear.

Will be promoted. By adjusting the frequency and phase of the three-phase alternating current, the speed of the moving magnetic field can be synchronized with the running speed of the vehicle. Thereby, the speed of vehicle 200 can be adjusted. In this case, each ground coil pair 11, 1
2 and the on-board coil 21 constitute a linear motor.

Next, the floating principle will be described with reference to FIG. The superconducting current i
0 flows as shown by the arrow in FIG. 5, and the coil elements 21a and 21b on the vehicle are made permanent magnets. This on-board coil 21 is the k-th lower ground coil 11 and k
In the case where the vehicle enters between the k-th ground coil pair including the upper ground coil 12, the on-board coil element 21
The following description focuses on a and the k-th lower ground coil element 11a and the k-th upper ground coil element 12a. First, when the on-board coil element 21a is located at the center of the space between the lower ground coil element 11a and the upper ground coil element 12a, an induced voltage generated in the lower ground coil element 11a and generated in the upper ground coil element 12a. Since the induced voltage and the induced voltage cancel each other, no current flows through either the lower ground coil element 11a or the upper ground coil element 12a. Therefore, in this case, no levitation force acts on the on-board coil element 21a.

On the other hand, the on-board coil element 21a is moved from the central position between the lower ground coil element 11a and the upper ground coil element 12a in one of the vertical directions in FIG. In the case of the vertical downward shift indicated by, an induced voltage that generates a magnetic field in the opposite direction to the magnetic field from the lower surface of the on-board coil element 21a approaching the lower ground coil element 11a is generated, An induced voltage is generated in the ground coil element 12a so as to generate a magnetic field in the same direction as the magnetic field from the upper surface of the onboard coil element 21a.
There is a difference between the induced voltage generated between 1a and the upper ground coil element 12a. As a result, the lower ground coil element 11a, the upper and lower connection wirings 13a and 13b, and the upper ground coil element 12a
a is generated. Due to this circulating current i2, the lower ground coil element 11a and the upper ground coil element 12a each become an electromagnet, and the lower ground coil element 11a
1a, a repelling force acts on the lower surface side, and the upper ground coil element 12a moves away from the on-board coil element 21.
Attraction magnetic force acts on the upper surface side of a.

When the on-board coil element 21a is displaced vertically upward from the center between the lower ground coil element 11a and the upper ground coil element 12a in the direction opposite to the direction of arrow D2 in FIG. By a function completely opposite to the above-mentioned function, the lower ground coil element 11a applies an attractive magnetic force to the lower surface side of the vehicle coil element 21a, and the upper ground coil element 12a functions as the vehicle coil element 21a.
A repelling magnetic force is applied to the upper surface side of a. Therefore,
The on-board coil element 21a includes a lower ground coil element 11a.
When it deviates from the center position between the ground coil element 12a and the upper ground coil element 12a, a restoring force acting to return to the center position acts. This restoring force is applied to the lower ground coil element 11a.
Is approximately proportional to the amount of displacement of the coil element 21a on the vehicle from the central position between the ground coil element 12a and the upper ground coil element 12a.

On-board coil element 21b, k-th lower ground coil element 11b, and k-th upper ground coil element 12b
The same operation is performed between and, in this case,
When the on-board coil element 21b is displaced from the center position of the lower ground coil element 11b and the upper ground coil element 12b in any vertical direction, the lower ground coil element 1
1b and the induced voltage between the upper ground coil element 12b and the lower ground coil element 11b and the vertical connection wiring 13
a, 13b and the upper ground coil element 12b, a circulating current (e.g., i3 when the vehicle coil element 21b is displaced in the direction D2) causes the vehicle coil element 21b to move to the lower ground coil element. A restoring force acts to return to the center position between the upper ground coil element 12b and the upper ground coil element 12b. Thus, the on-board coil 21 is
Since the vehicle is magnetically supported at a position corresponding to the vehicle weight between the ground coil pairs 11 and 12, the vehicle 200 floats.

Next, the principle of guidance will be described with reference to FIG. The superconducting current i
0 flows as shown by the arrow in FIG. 6, and the coil elements 21a and 21b on the vehicle are made permanent magnets. This on-board coil 21 is the k-th lower ground coil 11 and k
In the case where the vehicle enters between the k-th ground coil pair including the upper ground coil 12, the on-board coil element 21
a, 21b and k-th lower ground coil element 11a, 11
The description will be made focusing on b. First, the on-board coil element 21a
A line parallel to the traveling direction of the vehicle at the center line between the lower ground coil elements 11a and 11b is parallel to the traveling direction of the vehicle at the center line between the lower ground coil elements 11a and 11b. Line (hereinafter referred to as the "lower ground coil center line")
Is located above the lower ground coil element 11a.
The induced voltage generated in the lower ground coil element 11b and the induced voltage generated in the lower ground coil element 11b cancel each other out, so that no current flows through either of the lower ground coil elements 11a and 11b. Therefore, in this case, no guide force acts on the vehicle-mounted coil 21.

On the other hand, from the position above the center line of the lower ground coil, the center line of the on-board coil is in one of the horizontal directions in FIG. 6, when the vehicle is deviated to the right in the vehicle traveling direction indicated by arrow D3, an induced voltage that generates a magnetic field in the opposite direction to the magnetic field from the lower surface of the on-board coil element 21a moving away from the lower ground coil element 11a. On the other hand, since an induced voltage is generated in the lower ground coil element 11b so as to generate a magnetic field in the same direction as the magnetic field from the lower surface of the upper coil element 21b approaching the lower ground coil element 11b, the induced voltage generated in the lower ground coil elements 11a and 11b is generated. There is a difference between the voltages. As a result, the lower ground coil elements 11a and 11b
And a circulating current i4 circulating between the two is generated. Due to this circulating current i4, the lower ground coil elements 11a and 11a
b is an electromagnet, and the lower ground coil element 11a
Applies an attractive magnetic force to the lower surface side of the on-board coil element 21a that goes away. At the same time, the lower ground coil element 1
1b exerts a repulsive magnetic force on the upper surface side of the approaching vehicle coil element 21b.

When the center line of the on-board coil is displaced from the position above the center line of the lower ground coil in the leftward direction of the vehicle traveling direction, which is the opposite direction to the direction of arrow D3 in FIG. The lower ground coil element 11a exerts a repulsive magnetic force on the lower surface of the vehicle coil element 21a, and the lower ground coil element 11b exerts an attractive magnetic force on the upper surface of the vehicle coil element 21b. Let it work. Therefore, when the center line of the on-board coil is displaced from the position above the center line of the lower ground coil to one of left and right in the vehicle traveling direction, the center line of the on-board coil is set to the lower center line coil center line. A restoring force to return to the upper position acts. This restoring force is substantially proportional to the amount of deviation of the vehicle center line from the position above the lower ground line center line.

The same operation is performed between the on-board coil elements 21a and 21b and the k-th upper ground coil elements 12a and 12b. In this case, the center line of the on-board coil is moved to the upper ground coil elements 12a and 12b. From the position below a line parallel to the traveling direction of the vehicle (hereinafter referred to as the “upper ground coil center line”) at the center line between the left and right sides of the horizontal direction in FIG. , The induced voltage between the upper ground coil element 12a and the upper ground coil element 12b causes a difference, and the upper ground coil element 12a and the upper ground coil element 1
2b (for example, if the on-board coil elements 21a and 21b are displaced in the direction D3, i
According to 5), a restoring force acts to return the vehicle-mounted coil center line of the vehicle-mounted coil 21 to a position below the upper ground coil center line. Thus, the on-board coil 21
Is controlled by magnetic force in the middle of the ground coil pairs 11 and 12 so as to always maintain the position where the vehicle center coil center line is above the lower ground coil center line and below the upper ground coil center line. The vehicle 200 will be guided.

The coil winding shapes of the ground coils 11 and 12 as described above, the connection between the coil elements, and the upper and lower coils 1
Due to the connection between the coils 1 and 12 and the connection between the coil pairs 11 and 12 and the power transmission device, a propulsive force in the traveling direction, a levitation force, and a guide force on the left and right sides in the traveling direction act on the on-board coil 21. The above-described coil winding shape, connection between coil elements, connection between upper and lower coils, and connection between a coil pair and a power transmission device are hereinafter referred to as “PLG connection”. The lower ground coil 11 and the upper ground coil 12 correspond to a magnetic levitation type ground coil for propulsion, levitation, and guidance for a railway.

Therefore, the magnetic levitation railway according to the first embodiment has the following advantages. First, since guidance on the left and right sides in the traveling direction can be performed only by the two upper and lower ground coil pairs 11 and 12 provided on one guide beam, one of the left and right vehicle coils 21 and 21 can be guided. Even in the quench state, guidance can be provided without any trouble.

Further, since the on-board coil elements 21 a and 21 b constituting the on-board coil 21 are configured so that the current flows in the opposite directions, when one of the on-board coil elements becomes the N magnetic pole, , The other on-board coil element becomes an S magnetic pole. Therefore, the magnetic lines of force coming out of one of the on-board coil elements that become N magnetic poles enter the other adjacent on-board coil element in an arc-shaped curve without going to the outside. Therefore, the magnetic field leaking from the vehicle coil to the outside can be reduced.

Further, the lower ground coil 11 and the upper ground coil 12 are mounted on the guide beam 100, and a pair of the lower ground coil and the upper ground coil which are vertically opposed to each other is provided.
If a prefabricated member having a predetermined length integrally formed with a connection terminal T for performing a PLG connection between the paired coils and a connection with an adjacent guide beam is manufactured at a guideway construction site, The guide beams are arranged side by side on the left and right in the traveling direction, one side of the guide beam is connected in the traveling direction, and it is only necessary to connect to the power transmission device, and there is no need for null flux wiring between the left and right guide beams. Construction is simplified. Also, the guide beam 100
The connections inside are all fixed connections and have no moving parts, so that there is an advantage that the configuration is simplified, the manufacturing cost is reduced, and the number of failures is reduced.

The magnetic levitation railway according to the first embodiment has a feature in enhancing the magnetic levitation force. Hereinafter, this point will be described. As shown in FIGS.
Overhang portions 10a of left and right guide beams 100
A ferromagnetic plate 14 made of a ferromagnetic material containing soft iron, steel, cobalt, nickel, or an alloy thereof is formed on the upper surface 10d. Ferromagnetic plate 14
Are formed in a rectangular shape having the same size as the outer shape of the upper ground coil 12 and the vehicle coil 21, and are juxtaposed so as to be located immediately above the upper ground coil 12.

With the above-described configuration, the on-board coil 21 that has been turned into a permanent magnet by the superconducting current moves by propulsion, thereby generating a floating magnetic field in the upper ground coil 12 near the on-board coil 21. I do. The magnetic field for levitation is applied to the ferromagnetic plate 1 located immediately above the upper ground coil 12.
4 is temporarily magnetized. Therefore, the on-board coil 21
Is strongly attracted by the temporarily magnetized ferromagnetic plate 14 from above. Therefore, this attraction magnetic force can be used as a part of the levitation force of the vehicle, so that the ground coils 11 and 12 can be reduced in size accordingly. In this case, the upper ground coil 12 corresponds to an upper normal conducting coil, and the ferromagnetic plate 14 corresponds to a levitation force support member.

Since a part of the weight of the vehicle 200 is supported by the ferromagnetic plate 14 and the contact pressure is reduced, a sliding shoe (sliding leg member) can be used as an emergency braking means. Become.

When viewed from the side of the vehicle 200, the ferromagnetic plate 14 has a magnetic shielding effect of shielding a magnetic field that enters the seat 25 from the upper ground coil 12 and the on-board coil 21.

When utilizing the attractive magnetic force of the ferromagnetic member for the purpose of supporting the levitation force, instead of the above-mentioned ferromagnetic plate 14, a belt-like member made of a ferromagnetic material and extending in the traveling direction is used. The formed member may be arranged.

The magnetic levitation railway according to the first embodiment has a feature in the power collection method. Hereinafter, this current collecting method will be described. As shown in FIG.
In the lower part of 00, current collecting coils 22 are provided at left and right positions corresponding to the ferromagnetic plates 14, 14, respectively.

The ferromagnetic plates 14 are arranged side by side in the traveling direction, but there is a discontinuous portion where no ferromagnetic material exists between the plates. As described above, when the vehicle 200 travels at a high speed in the traveling direction, the ferromagnetic plate 14 near the on-board coil 21 is temporarily magnetized, and a magnetic field is generated accordingly. On the other hand, since no ferromagnetic material exists in the middle discontinuous portion of the ferromagnetic plate 14, no magnetic field is generated. For this reason, when the current collecting coil 22 passes over the intermediate discontinuous portion of the ferromagnetic plate 14, a change in the magnetic field occurs, and an induced electromotive force is induced in the current collecting coil 22. That is,
“Induction current collection” can be performed by this induction electromotive force. Further, in this case, the magnetic shielding plate 23 disposed at the lower part of the vehicle 200 exerts an action of increasing the induced magnetic field of the current collecting coil 22, so that the current collecting performance is further improved.

FIG. 7 is a conceptual diagram showing the configuration of the on-board coil and the ground coil for propulsion, levitation and guidance, and the principle of propulsion in the magnetic levitation railway according to the second embodiment of the present invention. FIG. 8 is a conceptual diagram showing the configuration of an on-board coil and ground coils for propulsion, levitation, and guidance, and the principle of levitation in a magnetic levitation railway according to a second embodiment of the present invention. FIG. 9 is a conceptual diagram showing the configuration of the on-board coil and the ground coil for propulsion, levitation and guidance, and the principle of guidance in the magnetic levitation railway according to the second embodiment of the present invention.

The magnetic levitation railway according to the second embodiment differs from the first embodiment in the configuration of the on-board coil and the ground coil, and the other configuration is exactly the same as that of the first embodiment.

It may be a single wire, or may be wound three or more times.

As shown in FIGS. 7, 8, and 9, the lower ground coil 11 'has a winding made of a normal conductive material having a substantially "b" shape.

The point P is set so that a 'and 11b' form a substantially "8" -shaped loop.
5 and P6. Each of the lower ground coil elements 11a 'and 11b' is formed by a double winding, and at the same position on the loop, current flows in the same direction in all the windings. When a current flows only in the lower ground coil element 11 ', the direction of the loop current flowing in the lower ground coil element 11a' is opposite to the direction of the loop current flowing in the lower ground coil element 11b '. Are connected to each other.

The same is true for the upper ground coil 12 ', and two upper ground coil elements 12a' and 1 whose windings made of a normal conductive material are wound in a substantially "L" shaped loop shape.
The points P7 and P8 are set so that 2b 'becomes a substantially "8" -shaped loop.
, And each upper ground coil element 1
2a 'and 12b' are formed by double windings, so that current flows in the same direction in both windings at the same location on the loop. Also, the upper ground coil 1
When a current flows only in 2 ′, the upper ground coil element 1
The two are connected so that the direction of the loop current flowing through 2a 'and the direction of the loop current flowing through upper ground coil element 12b' are opposite.

The upper ground coil 12 'has exactly the same arrangement as the lower ground coil 11' translated upward. The points P5 and P7 are connected by a vertical connection wiring 13a '(broken line), and the points P6 and P8 are connected by a vertical connection wiring 13b' (dashed line). Are connected to power transmission lines 15a ', 15a' (broken lines),
It is connected to a power transmission device (not shown). The winding in each ground coil element 11a ', 11b', 12a ', 12b' may be a single wire, or may be wound in three or more turns.

In FIGS. 7 to 9, the vehicle (vehicle coil 21 ') is assumed to travel from left to right in each figure, and ground coil pairs 11' and 12 'are oriented in the traveling direction of the vehicle. The ground coil pair on the left side is shown.

First, the principle of propulsion will be described with reference to FIG. The superconducting current i0 'is previously passed through the on-board coil 21' as shown by the arrow in FIG. 7, and the on-board coil 21 'is made permanent magnet. On the other hand, when the three-phase AC current 4i1 'is transmitted from an external power transmission device or the like via the power transmission wiring 15a' or the like (the other two are not shown), the k-th lower ground coil 11 'and k A current 2i1 'is supplied to each of the k-th ground coil pair consisting of the k-th upper ground coil 12', and the lower ground coil elements 11a 'and 11 constituting the k-th lower ground coil 11' are respectively provided.
A current i1 'flows through b', and a current i1 'also flows through upper ground coil elements 12a' and 12b 'constituting the k-th upper ground coil 12', respectively, and lower ground coil elements 11a 'and 11b'. And the upper ground coil elements 12a 'and 12b' respectively become electromagnets. In this way, the on-board coil 21 'can be attracted by the attraction magnetic force from each of the upper and lower ground coil elements in FIG.

Accordingly, a ground coil pair consisting of the lower ground coil 11 'and the upper ground coil 12' is continuously arranged side by side, and a three-phase alternating current is supplied to these ground coil pairs. 1
A moving magnetic field in the same direction (for example, the direction indicated by arrow D1 'in FIG. 7) can be simultaneously generated in 1' and the upper ground coil 12 '. The vehicle-mounted coil 21 ', which has been turned into a permanent magnet by the superconducting current, is attracted by this moving magnetic field and tends to move together with the moving magnetic field. ) Is promoted. By adjusting the frequency and phase of the three-phase alternating current, the speed of the moving magnetic field can be synchronized with the running speed of the vehicle. Thereby, it is possible to adjust the speed of the vehicle. In this case, each ground coil pair 1
1 ', 12' and the on-board coil 21 'constitute a linear motor.

Next, the floating principle will be described with reference to FIG. A superconducting current i0 'is previously passed through the vehicle-mounted coil 21' as shown by the arrow in FIG. 8, and the vehicle-mounted coil 21 'is formed as a permanent magnet. When the vehicle coil 21 'enters between a k-th ground coil pair consisting of a k-th lower ground coil 11' and a k-th upper ground coil 12 ', the vehicle coil 21' and the k-th lower coil The following description focuses on the ground coil element 11a 'and the k-th upper ground coil element 12a'. First, when the on-board coil 21 'is located at the center of the space between the lower ground coil element 11a' and the upper ground coil element 12a ', the induced voltage generated in the lower ground coil element 11a' and the upper ground coil element Since the induced voltage generated at 12a 'is canceled out, no current flows through either the lower ground coil element 11a' or the upper ground coil element 12a '.
Therefore, in this case, no levitation force acts on the on-board coil 21 '.

On the other hand, the on-board coil 21 'is moved from the center position between the lower ground coil element 11a' and the upper ground coil element 12a 'to one of the vertical directions in FIG. If it is shifted downward vertically as indicated by arrow D2 ', the lower ground coil element 11
a 'generates an induced voltage that generates a magnetic field in the opposite direction to the magnetic field from the lower surface of the approaching on-board coil 21', while the upper ground coil element 12a 'moves away from the upper surface of the on-board coil 21'. An induced voltage that generates a magnetic field in the same direction as the magnetic field from
There is a difference between the induced voltage generated between 1a 'and the upper ground coil element 12a'. As a result, the lower ground coil element 11
a ', circulating current i2 circulating between upper and lower connection wires 13a' and 13b 'and upper ground coil element 12a'.
'Occurs. Due to the circulating current i2 ', the lower ground coil element 11a' and the upper ground coil element 12a 'each become an electromagnet, and the lower ground coil element 11a' acts on the underside of the approaching onboard coil 21 '. At the same time, the upper ground coil element 12a 'applies an attractive magnetic force to the upper surface side of the on-board coil 21' which moves away.

The on-board coil 21 'is shifted vertically upward from the center between the lower ground coil element 11a' and the upper ground coil element 12a 'in the direction opposite to the direction of arrow D2' in FIG. In this case, the lower ground coil element 11a 'exerts an attractive magnetic force on the lower surface side of the vehicle-mounted coil 21' and the upper ground coil element 12a 'generates the attracted magnetic force by the operation completely opposite to the above operation. ′
A repulsive magnetic force acts on the upper surface side of. Therefore, when the vehicle coil 21 'is displaced from the center position between the lower ground coil element 11a' and the upper ground coil element 12a ', a restoring force for returning to the center position is applied. . This restoring force is applied to the lower ground coil element 11a '.
And the upper ground coil element 12a 'is approximately proportional to the amount of displacement of the vehicle coil 21' from the center position.

On-board coil 21 ', k-th lower ground coil element 11b', and k-th upper ground coil element 12b '
The same operation is performed between and, in this case,
When the on-board coil 21 'is displaced in any vertical direction from the center position of the lower ground coil element 11b' and the upper ground coil element 12b ', the lower ground coil element 1

Is shifted in the direction D2 ', a restoring force acts to return the vehicle coil 21' to the center position between the lower ground coil element 11b 'and the upper ground coil element 12b' by i3 '). become. In this manner, the on-board coil 21 'is magnetically supported at a position corresponding to the vehicle weight between the ground coil pairs 11' and 12 '.
The vehicle will surface.

Next, the principle of guidance will be described with reference to FIG. A superconducting current i0 'is previously passed through the vehicle-mounted coil 21' as shown by an arrow in FIG. 9, and the vehicle-mounted coil 21 'is formed into a permanent magnet. When the vehicle coil 21 'enters between a k-th ground coil pair consisting of a k-th lower ground coil 11' and a k-th upper ground coil 12 ', the vehicle coil 21' and the k-th lower coil Description will be given focusing on the ground coil elements 11a 'and 11b'. First, a line parallel to the traveling direction of the vehicle on the center line of the on-board coil 21 '(hereinafter referred to as "on-board coil center line") is defined by the center line between the lower ground coil elements 11a' and 11b '. Is located above a line parallel to the traveling direction (hereinafter, referred to as a "lower ground coil center line"), an induced voltage generated in the lower ground coil element 11a 'and an induced voltage generated in the lower ground coil element 11b'. Are mutually offset, the lower ground coil elements 11a 'and 11
No current flows in any of b '. Therefore, in this case, no guiding force acts on the on-board coil 21 '.

On the other hand, from the position above the center line of the lower terrestrial coil, the center line of the on-board coil is located in one of the horizontal directions in FIG. When the vehicle is shifted to the right in the vehicle traveling direction indicated by the arrow D3 'in FIG. 9, the lower ground coil element 11a' generates a magnetic field in the opposite direction to the magnetic field from the lower surface of the on-board coil 21 'moving away. While an induced voltage is generated, an induced voltage is generated in the lower ground coil element 11b 'so as to generate a magnetic field in the same direction as the magnetic field from the lower surface of the approaching onboard coil 21'. And 11b '. As a result, a circulating current i4 'circulating between the lower ground coil elements 11a' and 11b 'is generated. By the circulating current i4 ', the lower ground coil elements 11a' and 11b 'each become an electromagnet, and the lower ground coil element 11a' exerts an attractive magnetic force on the lower surface of the on-board coil 21 'which moves away. At the same time, the lower ground coil element 11b '
A repulsive magnetic force acts on the upper surface side of 1 '.

If the center line of the vehicle coil is shifted from the position above the center line of the lower ground coil to the left in the vehicle traveling direction, which is the opposite direction to the direction of arrow D3 'in FIG. By the operation completely opposite to the operation, the lower ground coil element 11a 'exerts a repulsive magnetic force on the lower surface side of the vehicle coil 21', and the lower ground coil element 11b 'operates on the upper surface side of the vehicle coil 21'. Apply magnetic attraction. Therefore, when the center line of the on-board coil is shifted from a position above the center line of the lower ground coil to one of left and right in the vehicle traveling direction, the center line of the on-board coil is set to the lower ground coil center line. Restoring force to return to the upper position is applied. This restoring force is substantially proportional to the amount of deviation of the vehicle center line from the position above the lower ground line center line.

The same operation is performed between the on-board coil 21 'and the k-th upper ground coil element 12a', 12b '. In this case, the center line of the on-board coil is shifted to the upper ground coil element 12a'. From a position below a center line between the center lines 12b 'and parallel to the traveling direction of the vehicle (hereinafter referred to as an "upper ground coil center line"), the horizontal direction in FIG. In any direction, the upper ground coil element 12
a 'and the induced voltage of the upper ground coil element 12b', a circulating current flowing between the upper ground coil element 12a 'and the upper ground coil element 12b' (e.g. If it shifts to D3 ', i5')
As a result, a restoring force acts to return the on-board coil center line of the on-board coil 21 'to a position below the upper ground coil center line. Thus, the on-board coil 21 '
Is controlled by magnetic force so as to always maintain a position where the vehicle center coil center line is above the lower ground coil center line and below the upper ground coil center line between the ground coil pairs 11 'and 12'. Therefore, the vehicle is guided.

Each of the ground coils 11 ', 12' as described above
Coil connection shape, connection between coil elements, connection between upper and lower coils 11 ', 12', and coil pair 11 ', 1
Due to the connection between the power transmission device 2 'and the on-board coil 21', a propulsive force in the traveling direction, a levitation force, and a guide force on the left and right sides in the traveling direction act on the on-board coil 21 '. The above-described coil winding shape, connection between coil elements, connection between upper and lower coils, and connection between a coil pair and a power transmission device correspond to PLG connection. Further, the lower ground coil 11 'and the upper ground coil 12' correspond to ground coils for propulsion, levitation and guidance for a magnetic levitation railway.

Therefore, in the magnetic levitation railway according to the second embodiment described above, guidance on the left and right sides in the traveling direction can be performed only by the ground coil pairs 11 'and 12' of one guide beam, and the left and right vehicles can be guided. There is an advantage that a guide can be provided without any trouble even when one of the coils is in a quench state, and that there is an advantage that a guideway with a simple configuration and low production cost can be provided.

Anything is included in the technical scope of the present invention.

For example, in each of the above embodiments, in each of the left and right guide beams, two ground coils, which are normal conducting coils, are arranged so as to vertically sandwich a vehicle-mounted coil which is a superconducting coil. Although an example in which the plane of each coil is a horizontal plane has been described, the present invention is not limited to this, and other coil arrangement methods, for example, a vehicle in which a ground coil that is two normal conducting coils is a superconducting coil. The coils may be arranged so as to be sandwiched between the left and right, that is, the plane of each coil is a vertical plane. Or, a state in which the ground coil, which is two normal conducting coils, obliquely sandwiches the on-board coil, which is the superconducting coil,

As described above, according to the present invention,
A pair of normal conducting coils on the ground side
Since the superconducting coils on the vehicle side are arranged to be sandwiched independently of each other, even if the superconducting coils on the vehicle side are in a quench state, guidance can be performed without any trouble. Further, the guideway can be configured by a member fixedly connected to only one of the left and right sides, and null flux wiring on the left and right sides of the guideway becomes unnecessary. Further, if each coil is formed into an 8-shaped loop, the amount of the magnetic field of the vehicle-side coil that leaks to the outside can be particularly reduced. Further, by arranging the ferromagnetic member above the upper coil of the ground side normal conducting coil, it is possible to support the magnetic levitation performance, and it is also possible to perform magnetic shielding for the vehicle side. Further, the ferromagnetic members can be arranged discontinuously at predetermined intervals, a current collecting coil can be provided on the vehicle side, and current can be collected by a change in the magnetic field accompanying the running of the vehicle.
