For this reason, the magnetic shielding effect inside the connection portion can be further enhanced.

Further, the magnetic shield structure of the magnetic levitation railway vehicle according to claim 2 employs a plank as contactor.
As is well known, the contact between the crossover plates can be maintained by allowing relative displacement between the vehicles in the front-back, left-right, and up-down directions.

When a relative displacement occurs in the vertical direction, the displacement is allowed by sliding on the XZ plane or the YZ plane. Therefore, even if relative displacement occurs between vehicles,
The magnetic path in the front-back direction is continuously formed without being cut in the middle, and the magnetic shielding effect inside the connecting portion is maintained.

Further, in the magnetic shielding structure of a magnetic levitation type railway vehicle according to the fourth aspect , the flexible high-permeability material that connects the vehicles can provide relative displacement in the front-back, up-down, left-right directions between the vehicles. Can be tolerated. Therefore, even if a relative displacement occurs between the vehicles, the magnetic path in the front-rear direction is not cut in the middle and is continuously formed, and the magnetic shielding effect inside the connecting portion is maintained.

Furthermore, in the magnetic shielding structure of the magnetic levitation type railway vehicle according to the fifth aspect, the partition member capable of permitting relative displacement prevents a passenger from entering a portion having a high magnetic field strength. Therefore, a portion of the inside of the connecting portion partitioned by the partition member has a higher magnetic shielding effect.

It is composed of a connecting member 60 and crossover plates 42, 52 provided at the ends of the floor surfaces of both connecting frame portions 41, 51.

The connecting frames 41 and 51 are connected to the vehicles 40 and 50, respectively.
Except that the floors and ceilings of the throughways 43 and 53 provided in the passenger compartment are extended and tapered so that the side faces are open to the other vehicles 50 and 40, This is the same as the connection frame portions 11 and 21. That is, the connection frame 41,

The contacts 74 and 84 provided at the end of the side surface of 81 and both contacts 7
4 and 84, and is constituted by an intermediate member 94 which comes into contact therewith.
Further, in the present embodiment, for convenience of explanation, the front-rear direction of the vehicles 70 and 80 is defined as an X-axis, the left-right direction is defined as a Y-axis, and the vertical direction is defined as a Z-axis.

The connection frame 71 is substantially the same as the connection frame 11 of the first embodiment, and is formed by a shield 71a and a portion 71b other than the shield 71a. However, a contact 74 having an XZ plane is formed on the shield part 71a of the connection frame part 71 by extending and bending the end part thereof.

The connection frame 81 is substantially the same as the connection frame 21 of the first embodiment, and is formed by a shield portion 81a and a portion 81b other than the shield portion 81a. However, a contact 84 having a YZ plane is formed on the shield portion 81a of the connection frame portion 81 by extending and bending the end portion thereof.

The intermediate member 94 is formed by forming an L-shaped magnetic shield plate, and includes an XZ plane slidable on the XZ plane of the contact 74 and a YY slidable on the YZ plane of the contact 84.
And a Z plane. This intermediate member 94 is connected to the vehicle 70

YZ plane. The elastic member 95 is fixed to an elastic member mounting plate 96 erected on the rear surface of the vehicle 70.

The airtight connecting member 90 and the transition plates 72 and 82 are
Since they are almost the same as the hermetic connection member 30 and the transition plates 12 and 22 of the first embodiment, description thereof will be omitted. As a result of the above configuration, the connecting portions 88 of the vehicles 70 and 80 have the shielding portions 71a of the connecting frame portions 71, the connecting plates 72, the connecting plates 82, and the shielding portions of the connecting frame portions 81, as in the first embodiment. 8

a, the contact 74, the intermediate member 94, the contact 84, and the shield portion 81 a of the connection frame 81 form a second magnetic path in the front-rear direction.

The operation and effect of the magnetic shielding structure of the connecting portion 88 having the above configuration will be described below. It has been found from examination results that the direction of the magnetic flux by a superconducting magnet (not shown) arranged under the floor of the connecting portion 88 is dominated by the magnetic flux in the front-rear direction of the vehicle. Since this magnetic flux passes through the first and second magnetic paths, the through path 93 provided inside the connecting portion 88 is magnetically shielded.

The operation and effect of the crossover plates 72 and 82 and the airtight connecting member 90 when the relative displacement occurs between the two vehicles 70 and 80 are the same as in the first embodiment. Also, the first
Like the magnetic path of the first embodiment, even if a relative displacement occurs, the magnetic path is continuously formed without being cut in the middle, and the magnetic shielding effect of the through passage 93 in the connecting portion 88 is maintained. Is retained.

Subsequently, the contacts 74 and 84 and the intermediate member 94

When a relative displacement in the front-rear direction, that is, in the X-axis direction occurs between the contact members 84, the YZ plane of the intermediate member 94 is moved by the elastic member 95.
Are held in contact with each other, and the two 94 and 84 maintain a contact state. On the other hand, the XZ plane of the intermediate member 94 is
Since the contact 74 slides on the XZ plane,
4 keeps the contact state.

The right and left direction, ie, Y, between the two vehicles 70 and 80
When the relative displacement in the axial direction occurs, the XZ plane of the intermediate member 94 is pressed against the XZ plane of the contact 74 by the elastic member 95, so that the two members 94 and 74 maintain the contact state.
On the other hand, since the YZ plane of the intermediate member 94 slides on the YZ plane of the contact 84, the two members 94 and 84 maintain the contact state.

The vertical direction, Z, between the two vehicles 70, 80
When a relative displacement in the axial direction occurs, the XZ plane and the YZ plane of the intermediate member 94 are respectively contacted by the elastic members 95 with the contacts 74.
While being pressed by the XZ plane of the
Slides in the axial direction. Therefore, even if a relative displacement occurs between the vehicles 70 and 80, the second magnetic path in the front-rear direction is not cut off in the middle and remains formed continuously, and the connecting portion 8
The magnetic shielding effect of the through passage 93 in 8 is maintained.

In the present embodiment, the second magnetic path is formed in addition to the first magnetic path.
It is further enhanced as compared with the first embodiment. Also, since a large relative displacement can be tolerated, displacement between vehicles in the event of an abnormality can be escaped, and it is not necessary to install a displacement suppressing mechanism that affects the strength of the structure such as restraint between vehicles. This has the effect of reducing the weight of the vehicle.

Next, a fourth embodiment will be described. 4th
The embodiment is an example of a magnetic shielding structure in which a magnetic path is formed in the front-rear direction using the high-permeability woven fabric 2 for the airtight connection member 30 of each of the first embodiments. FIG. 7 is an explanatory diagram of the high-permeability woven fabric 2. The high-permeability woven fabric 2 includes a cloth 5 in which fibers 3 having a high magnetic permeability are arranged in the front-rear direction of the vehicles 10 and 20 and fibers 4 having an appropriate strength are arranged in the up-down direction. It comprises high-permeability strips 6 and 7 provided at both ends. In the two vehicles 10 and 20, the high permeability strips 6 and 7 provided at both ends of the high permeability woven fabric 2 are attached to the ends of the connecting frame portions 11 and 21 of the vehicles 10 and 20. Are linked.

As a result, the connecting portion 28 of the vehicles 10 and 20 is connected to the shield portion 11a of the connecting frame portion 11, the fiber 3 of the high-permeability woven fabric 2, and the shield portion 21a of the connecting frame portion 21 by the vehicle. A magnetic path is separately formed in the front-back direction. Also,
The high-permeability woven fabric 2 has flexibility since it is a woven fabric of the fibers 3 and the fibers 4. Therefore, vehicles 10, 2
A relative displacement in the front-back, up-down, and left-right directions between 0 can be allowed. Therefore, even if a relative displacement occurs between the vehicles 10 and 20, this magnetic path is continuously formed without being cut in the middle, and the magnetic shielding effect of the through path 33 in the connecting portion 28 is maintained. Is done. In the present embodiment, by forming this magnetic path separately, the magnetic shielding effect of the through passage 33 is further enhanced as compared with the first embodiment.

The magnetic shield material of each of the above embodiments and the fourth embodiment
Since the high magnetic permeability fiber 3 of the embodiment needs to sufficiently flow the magnetic flux in the front-rear direction of the vehicle, it is represented by, for example, industrial pure iron having a low carbon content, magnetic steel sheet containing silicon, and the like. It is preferable to use a material having a high magnetic permeability and a high saturation magnetic flux density. Here, the high magnetic permeability is an index indicating the property of allowing a large magnetic flux density to flow with a small magnetizing force.

FIG. 8 is a graph showing a DC magnetization curve and a DC magnetic permeability curve of a magnetic steel sheet containing silicon. FIG. 9 shows a graph of ordinary iron for comparison. Magnetizing force generated around a maglev railway vehicle is
Usually, it is in the range of 100 to 500 [A / m]. Within this range, the silicon-containing electromagnetic steel sheet shows a higher magnetic flux density than ordinary iron, and particularly has a magnetizing force of 100 to
The difference is remarkable in the range of 300 [A / m]. In addition, the preferable numerical range of the magnetic flux density in the range of the magnetizing force is 1.0 to 1.4 [Tesla].

It is needless to say that the present invention is not limited to the above embodiments and can be carried out in various modes without departing from the gist of the invention. For example,
The crossover plate of the connecting portion may adopt, for example, the structure shown in FIG. 10 in addition to the one shown in the above embodiment. That is, the connecting portion 112a and the connecting portion shield portion 121a are formed by the connecting plate 112 having two projections on the lower surface.
May be employed. This transition board 112
According to this, even when relative displacement between the vehicles occurs, the magnetic path is continuously formed without being cut, and the same effects as those of the above embodiments can be obtained.
