Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to levitation, guidance, and
This relates to the combined propulsion device 6.

(Conventional technology) Induction-repulsion type magnetic levitation' two railways are well known.

An example of the perspiration, guidance, and propulsion mechanism will be explained with reference to FIGS. 10 to 13.

20.20' is a superconducting coil mounted boldly on both sides of the bogie 9 of +i i+T4 V, and 21.21' is a superconducting coil that is continuous horizontally on the bottom surface along the vehicle traveling direction of the trackway 13 having a U-shaped cross section, for example. 22 and 22' are conductors such as levitation conductor coils or conductive sheets arranged in the relationship shown in FIG.
Conductor coils for guiding and propulsion are vertically and continuously arranged at a predetermined interval on both sides of the inside of the superconducting coil 20, 20', and are arranged so as to be electromagnetically coupled to the superconducting coil 20, 20'.

Vehicle ■ has conductor coil 21.21' and superconducting coil 2.
A floating blade is provided by 0.20' and propelled and guided by the conductive coil 22.22° and the superconducting coil 20.20°.

This point will be explained with reference to FIGS. 11(a) to 13.

In Fig. 11 (a>), 20.20° is the loop-shaped superconducting coil shown in Fig. 10.

Normally, adjacent superconducting coil beams have opposite polarity. 2
1.21' is the conductor coil 21.21 in FIG.
°.

Even with this configuration, as long as the vehicle V is stopped, the superconducting coil 20.20' and the conductor coil 21.2 on the vehicle
1', no electromagnetic interaction occurs. A superconducting coil 20.20'' installed on the vehicle V and a propulsion guide conductor coil 22 installed on the trackway 13,
The vehicle V is made to travel by a linear motor configured with an angle of 22 degrees.

As a result, the superconducting coil 20.20' becomes the conductor coil 2.
1.21', the superconducting coil 20
．． A current is induced in the conductive coils 2+, 2+' by 20'. This induced current increases with the running speed of the vehicle, becomes almost saturated at a certain running speed, for example, about 200 km/h, and remains at the same level as long as the vehicle runs at a higher speed.

That is, the conductor coil 21.2 shown in FIG. 11(a)
Figure 11 (b
) are interlinked, and a voltage e for the float 1 shown in FIG. 11(C), which is also drawn correspondingly in position, is induced. ) will flow as shown in FIG. In this case, if the current in the superconducting coil 20 flows in the direction of arrow a as shown in Figure 1(e), the current induced in the conductive coil 2 by the current flows in the right direction. As a result, floating blade 1'=B X i is obtained according to Fleming's left-hand law. Here, B is the magnetic flux density created by the superconducting coil 20.20°, and i is the current flowing through the conductive coil 21.21'. In other words, vehicle ■ has a superconducting coil of 20.20
' is caused by the repulsive force acting between the current induced in the conductor coil 21%21°.

Next, we will discuss the guidance and propulsion effects of both Ili and ■.

The cross sections h1 of the conductor coils 22.22° are all set to be the same, and they are connected by a null flux as shown in FIG. When the vehicle is running, let φg and φg' be the magnetic fluxes interlinked by the superconducting coils 2o and 20° to the opposing conductor coils 22 and 22°, respectively.
11 If there is no displacement in the left and right direction, φg = φg°
Therefore, the magnetic flux linkage for l pairs of coils is φg−φg'
= Q, so no current is induced and no guiding force is generated, but when the vehicle is displaced in the left-right direction, φg>φg' (when the vehicle is displaced to the right), or φg - φg.

(when the vehicle is displaced to the left), the interlinkage magnetic flux as a pair of coils is φg - φg゛; ±△φg゛, and the current as shown by the solid line in Fig. 13 is in the coil 22.22゛. The flow and repulsion generate a guiding force in the direction of eliminating the displacement, which is proportional to the displacement.

On the other hand, as shown in FIG. 13, a three-phase or multi-phase power source 23 for propulsion is connected to the conductive coil 22 for both propulsion and guidance. .22°, currents flow in the same direction as indicated by the dotted arrows, so according to Fleming's left-hand rule, ilj and ■
A driving force is generated that promotes.

In this method, medium-weight power running 4 coasting, braking and stopping 1
-, etc. are from the power supply 2/3 to the conductor coil 22 used in combination with the propulsion guide.
．． This is done by controlling the current flowing at 22°.

When the vehicle (■) starts running due to the propulsion force generated by the conductor coil 22.22' which also serves as a propulsion guide, the 1 degree force of the vehicle is applied by the superconducting coil 20.20° and the conductor coil 21.2B, and the superconducting The guiding force of the vehicle is generated by the coil 20.20° and the conductor coil 22.22°,
After the vehicle (1) reaches a certain speed or higher, the wheels 12 are retracted and the vehicle is guided by the floating F while maintaining a constant levitation force. When the running speed falls below a certain speed, the buoyancy force decreases and the vehicle lands on the ground track 13 via the pulled-out wheels 12.12. Note that 10 is a mechanical guide wheel whose one end is pivotally connected to the other end of a shaft 11 fixed to the vehicle.
It assists in guiding while rotating along the side of the machine.

However, this maglev railway is i? The ground conductor coil 21.21' of l-Jll is placed horizontally at the center of the bottom of the trackway, and the superconducting coil 20.20 on the IIT
Since the m4 electric coil 21.° is installed in the polished surface direction on the side surface of the bogie 9 located in the side direction of the trackway, the m4 electric coil 21.
It is necessary to flow a large induced current through 21', and there is a limit to reducing the loss of the levitation conductor coil 21, 21'. In other words, there is a limit to how low running resistance can be made.
Furthermore, since an unstable spring in the horizontal direction is generated from the levitation conductor coil 21.21 degrees, it is necessary to generate a sufficiently stable spring at the conductor coil 22.22 degrees used for both propulsion and guidance.

(A problem to be solved by the invention) In view of the above-mentioned current situation, the present invention is capable of effectively exerting all the functions of propulsion, levitation, and guidance with a pair of simple conductive coils, and moreover, compared to conventional methods. The object of the present invention is to provide a combined levitation, guidance, and propulsion device that can significantly reduce running resistance and has a stable levitation and guidance function.

(Means for solving the problem) Claim 1 A vehicle in which superconducting fills are vertically arranged continuously at predetermined intervals on both sides along the vehicle traveling direction is floated and guided along a track path, The model is a guided repulsion magnetic levitation railway.

(1) Place one conductor coil and the lower conductor coil facing each other on both sides of the trackway. The upper conductor coil and the L-side conductor coil are each connected by a null flux.

The conductor coils configured in this manner are arranged at predetermined intervals along the traveling direction of the vehicle. The 14 conductor coils and the other L conductor coils facing the 14 conductor coils are further connected by a null flux via a connecting wire. Claim 2, wherein the connection line is provided with a propulsion power source. When the vehicle is running via the auxiliary small wheels, the conductor is connected to a superconducting coil mounted on the vehicle and placed on the trackway, which is connected by a null flux. The coils are set in a positional relationship such that the phase 11° inductance between them is zero.

(0 river) When the power vehicle is running at low speed via the auxiliary wheels, the interlinkage magnetic flux of the opposing conductive coil is O1, the current is 0, and the electromagnetic running resistance is O.

When a vehicle is running in levitation, a difference occurs in the interlinking magnetic flux between the upper and lower coils, which induces a current and generates a levitation force that attempts to return the superconducting coil upwards, bringing it to a position where it balances with the weight of the vehicle. becomes stable.

When the guiding force vehicle is displaced in the left-right direction, a difference occurs in the interlinking magnetic fluxes between the opposing upper coils and the lower coils, a current is induced, and a guiding force is generated that returns the superconducting coils to the center.

The propulsion power source is connected to the opposing conductive coils via a connection line, and current flows in the same direction through the upper fill and lower coils, generating propulsive force on the right side.

(Example) 1 As described above, the conventional induction repulsion type magnetic floating railway shown in FIGS. 10 to 13 has a floating conductor coil 21.
．． It is necessary to flow a large induced current in 2+', and there is a limit to reducing the loss of the levitation conductor coil. That is, there is a limit to how low the running resistance can be, and unstable springs are generated in the horizontal direction from the levitation conductor coils 21, 21'.

It is necessary to generate a sufficiently stable spring at 22.22° in the conductor coil for both propulsion and guidance.

Under such circumstances, it has been found that the configuration shown in FIGS. 3 to 6 is extremely effective as a mechanism for reducing the running resistance of the vehicle.

When the configuration shown in FIG. 3 is compared with the conventional configuration shown in FIG. 10, it is found that in FIG. The conductor coil 15 is placed at the same position as the coil 20.20° and the conductor coil 22.22° which also serves as guide and propulsion.
．． 16. Electric conductor coil for both levitation and propulsion between 15 degrees.
16゛, conductor coil +5. The difference is that +5° is used as a conductive coil exclusively for guidance.

? ? The conductor coil 16.16' used for I-1 propulsion is the same as the conductor coil 17.1 having the same shape and dimensions.
8.17° and 18゛ are placed on one side and below the same line l-, and they are connected by a null flux.
A three-phase or multi-phase propulsion power source 23 is connected to the null flux connection part of.

When the vehicle V is running at low speed via the wheels 12.12, the eastward center of the superconducting coil 20.20', the vertical center of the conductor coil 16.16' for levitation and propulsion, and the guiding conductor The specifications are set so that the centers of the body coils 15 and 15' in the center direction are on the same water line.

The conductor coils 17, 18 and 17°, +8° are arranged symmetrically in the -1-1 downward direction about the vertical center of the conductor coils 16 and 16°, which also serve as floating and dual propulsion.

In such a configuration, when +lj both run at low speed, the magnetic flux linkage for levitation in the L force coils 1F and 17゛ and the F side coils 18 and 18゜ becomes 0 and the current becomes O, so the electromagnetic running resistance is O.

While the vehicle V is running in levitation, the center of the superconducting coil 20°20° is balanced in the direction F from the center of the levitation and propulsion conductor coil 16.16°, and the current is flowing through the upper conductor as shown in Figure 5. It flows in the opposite direction in coils 17 and 18 and the vehicle's t'71
- A force is generated, but the floating two-wheel conductor coil 2 in Figure 1O
Since the levitation force is generated more effectively than the current flowing at 1.21°, the amount of current flowing can be reduced, and therefore the electromagnetic running resistance can be reduced.

On the other hand, the power supply current supplied to the conductor coil 16.16° for levitation propulsion is as shown in Figure 6.
7. Since the flow flows in the same direction in the lower coil 18,
Propulsive force is generated around.

Guidance of the vehicle by the guide conductor coil 1515' in this system is performed according to the same principle as that of the conductor coil 22 also used for propulsion and guidance shown in FIGS. 10 to 13.

In this system, a conductor coil 16 is used for both levitation and propulsion.
16°, like the guiding conductor coils 15 and +5', are arranged vertically facing the superconducting coils 20 and 20', so a stable left and right spring is generated, and the guiding conductor coils +5. The spring generated from +5° can be small.

It has been found that the structure shown in FIGS. 7 to 9 has a force of 41 as a structure for reducing the running resistance of the vehicle.

Comparing this second promising method with the first method shown in FIGS. 3 to 6, the guiding conductor coil 15 of the first method is
．． The conductor coil 24 provided at the 15° position is used as a propulsion-only conductor coil, and the conductor coil +61 has the same configuration as the floating conductor coil 16, +6' for both propulsion in the first method. , +61° is used as a conductive coil that also serves as levitation guide, and is arranged on opposite sides of the trackway 161°161
' are different in that they are null-flux connected via connecting wires 162 and 163 so that the induced voltages induced in the coils above them are canceled out.

In this method, the vehicle's floating blade is as shown in Figure 8.
This occurs based on the same principle as shown in FIG. 5 in the first method.

On the other hand, a conductive coil 161 which also serves as a floating guide and upper coils 171 and 17 of +6 Bi are arranged on opposite sides of the trackway.
1' are null flux connected via connection wires 162 and 163, so if the superconducting coil 20.20° is not displaced in the left-right direction, no electromagnetic action will occur, and the magnetic flux of each coil will be 0, the current is O, but
When the superconducting coil 20.20' is displaced in the left-right direction,
On the other hand, a difference occurs in the magnetic fluxes interlinking between the coils +71 and 171' and the lower coils 181 and 181', and a current as shown in FIG. A guiding force is generated that tries to return it. Moreover, the current that generates the guiding force hardly affects the floating blade.

The feature of this method is the conductor coil 24 dedicated to propulsion.
The levitation guide system is constructed electrically and separately.

The present invention utilizes the induction-repulsion magnetic a1/guide propulsion system, which is effective in reducing the running resistance of the vehicle as described above, and ensures stable performance with an extremely simplified mechanism. The purpose of this project is to provide a device that combines floating, guidance, and propulsion.

The present invention will be explained according to the embodiment shown in FIGS. 1 to 2(b).

In FIGS. 1 and 2, the same symbols as in FIGS. 3 to 1; 3 do not indicate the same components.

1.1° is a conductor coil having the same configuration as 16.16° in FIG. 3 and 161.161° in FIG. It consists of a closed circuit with a null flux connection. For example, the conductive coils 1, 1' are continuously arranged at predetermined intervals along both the inner side surfaces of the trackway 13 having a tJ-shaped cross section in both directions of travel. The upper coil 2 of the conductor coil l and the upper coil 2 of the conductor coil 1° facing it
A null flux connection is made between the two via connection lines 4 and 5 as shown in FIG. 2(a). Vehicle V has auxiliary wheels 12.12
The center of the superconducting coil 20.20' in the vertical direction and the conductive coil 1.1' when the superconducting coil 20.20' is seated on the ground.
11°lThe center of the force direction is set to be on the same horizontal line.

A three-phase or multi-phase propulsion heavy source 6 is connected to connection VA4.5.

Hereinafter, the present invention configured as described above will be explained in detail.

r'? , upper blade: When the vehicle ■ is running at low speed via the auxiliary 11i wheels 12.12, the order 1n relationship between the superconducting coil 20°20° and the conductive coil 1.1° is set as described above. , and the lower coils 2 and 3 and 2' and 3° are null flux connected, so the conductor coils 1, ! The interlinkage flux of ゛ is 0, the current is 0, and the electromagnetic running resistance is 0.

When the vehicle V is running floating with the auxiliary wheels 12 retracted, the center of the superconducting coil 20.20° in the stacking direction is the conductive coil 1. The width II' of l' shifts from the center in the 1 direction to the do direction, and a difference occurs in the interlinking magnetic flux between the 1st coil and the lower coils 2 and 3 and between 2nd and 3rd, and the 1st coil and the lower coil A current as shown in Figure 2 ([)] is induced in 1
By repulsion and attraction, the superconducting coil 20.20'
A γf1- force is generated that tries to return the
It is stable in a position that is balanced with the force. In this case as well, the first coil and the lower coils 2, 3, 2°, and 3′ effectively generate the a1 force with a small current, so that the electromagnetic running resistance can be reduced.

When the guide crab vehicle ■ is located in the center of the track, the conductor coil 1
．． 1° are arranged symmetrically with respect to the longitudinal centerline of the trackway, and the opposite lower coil 2.2° is connected to the connecting wires 4, 5.
Since the 5 conductor coils are null flux connected through 1. The flux linkage at l° is O5, the current is O, and the electromagnetic running resistance is O. While the floating boat is traveling, when both +lj and V are displaced in the left and right direction, a difference occurs in the interlinking magnetic flux between the lower coil 2 and 2° and between the lower coil 3 and 3°,
A similar current is induced when flowing through the conductor coils 16+ and 161° in FIG.
．． A guiding force is created that returns the 20° to the center.

As shown in FIG. 2(a), the current for propelling the propulsion crab is supplied to the conductor coil 1 via the connection point 7 of the connection line 4 from the three-phase power supply 6, for example.

Current flows in the same direction as shown by the arrows in so, and a propulsive force is generated on the vertical side. In addition, -[In the above embodiment, an example was described in which a type II cross section was used as the trackway, but it is also possible to use a trackway with a divine shape, such as a box-shaped cross section, and the shape of the trackway may be , but is not limited to this. In addition, in the first embodiment, the 1-1 coil 2.2° and the lower coil 3.3' are disposed 6 on the track path.
Although we have described an example in which the coils 2.2° and 3.3' have the same shape and the same size, even if these coils 2.2° and 3.3' are not the same shape and size (in this case, is different, when the center of the !fE rectangular white direction of the super-u conductor coil 20.20° is on the same long F line as the center of the superimposed direction of the conductor coil 1.I', the interlinkage magnetic flux becomes 0. However, at a position where the mutual inductance between the superconducting coil 20, 20' and the conductor coil 1, lo becomes 0, the interlinkage magnetic flux becomes 0, and the electromagnetic running resistance becomes 0.

Accordingly, in the present invention, the superconducting coil 20.20° and the conductive coil 1.1° are set to have such a 1n relationship during ili-wheel running. Therefore, in the present invention, the coils 2.2', 3, and 3° have the same shape and the same -
It includes whether or not the Il method is used.

(Effect of the invention) The main effects of the present invention are as follows.

1) As for the ground J general equipment, it is only necessary to continuously install a pair of conductive coils on both sides of the trackway, so it is extremely simplified compared to the conventional method shown in Figure 10. .

Therefore, when laying the track, there is no need to control the design accuracy of the bottom surface of the trackway as in the past, and the investment capital for laying can also be reduced.

2) The electromagnetic running resistance during driving in light rain can be suppressed to zero or extremely small, thereby making it possible to save energy consumption for heavy vehicle driving compared to the conventional technology.

Furthermore, unlike in the conventional system, unstable springs in the left and right directions do not occur, and stable floating 19 and guiding force are guaranteed.

In the second 41-way method, there is a connection line +51 buried in the trackway connecting 5 and I5°, and connection lines 162 and 163 connecting 161° and the conductive coil 16+ that also serves as a guide. If the power supply for
Since no voltage is applied, the conductor coil and connecting wire can be used for low voltage. In contrast, the present invention is characterized in that a pair of conductor coils l, I' performs all the functions of levitation, guidance, and propulsion, so that the conductor coils 1, ! and the connecting wires 4.5 that connect them must be of high voltage resistance. But for promotion.

The degree of high voltage that must be applied is determined by the Ichikawa of the moving body, more specifically, the number of strokes of the train formation type, and if the formation H1j1I is reduced, the applied voltage can be reduced by that amount. Design and implementation for high voltage resistance become easier. In this zero taste, the present invention is relatively
It is suitable as a guide and propulsion device for trains with little loss of formation.
