[0001]

BACKGROUND OF THE INVENTION 1.

Reducing magnetic levitation train vehicles.

2. Description of the Related Art As a conventional technique relating to a magnetic levitation train, for example, there are techniques disclosed in Japanese Patent Application Laid-Open Nos. 4-353068 and 4-140003.
Its contents are to arrange the levitation coil and the propulsion coil on the track. A magnetic levitation train is generally used in which a superconducting magnet is disposed on the vehicle side facing these coils, and the train is propelled while the vehicle levitates by the repulsive force of the magnet.
In addition, as means for maintaining the stability during running of the magnetic levitation train, by discharging compressed air from the side of the vehicle to the guideway, yawing or pitching of the vehicle body is prevented, and the train moves along the guideway. There is a method to ensure the stability of the vehicle body while traveling.

[0003]

The drawbacks of the prior art magnetic levitation train vehicles are that they require high construction costs for laying tracks and cannot be applied to existing railway networks.

[0004] The reason is that according to the whole on the track of the train,
Since it is necessary to arrange the magnetic levitation coil and the propulsion coil, considerable construction cost is required as described in the related art. Furthermore, since it is not applicable to the conventional railway network using the existing rail track, it is necessary to lay a new track separately from the existing railway network.

Accordingly, an object of the present invention is to reduce the sway of a conventional vehicle by magnetic levitation of a passenger car unit by applying technology to an existing railway vehicle without newly constructing a large railway track. The vibration and sway of the vehicle can be reduced by magnetic levitation of the passenger car.

SUMMARY OF THE INVENTION It is an object of the present invention to magnetically levitate a train (passenger car unit) to reduce vibrations and shaking. A further object of the present invention is to reduce the vibration and shaking of a passenger car by applying the method to a conventional vehicle in an existing railway network without newly constructing a railway track.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reduce the vibration and sway of a conventional vehicle by installing an additional portion for applying another technology to an existing railway vehicle without newly constructing a large railway track. The object of the present invention is to realize a magnetic levitation of the passenger compartment, and to reduce the movement due to the vibration due to the vibration and shaking of the conventional vehicle by the magnetic levitation of the passenger compartment.

[0008] An object of the present invention is to reduce vibrations and vibrations by magnetically levitating the passenger compartment of a train. The first object of the present invention is to reduce the vibration and sway of the passenger compartment by applying to existing vehicles in an existing railway network without newly constructing a railway track.

A maglev train vehicle according to the present invention comprises a pantograph for a last train, a passenger compartment for accommodating passengers, and a bogie unit on which the cabin unit is mounted. A first superconducting coil is provided on both side ends thereof as viewed from above, and a second superconducting coil corresponding to the first superconducting coil is provided inside the passenger car portion and at the bottom of the passenger compartment. A coil having a superconducting material as a conductor is provided, and a coil having a superconducting material as a conductor is installed in the bogie portion. Is generated by the excited coil, an induced current is generated in the coil provided on the bogie of the train, a repulsive force is generated between the two coils, and the passenger car portion is levitated.

[0010] In the magnetic levitation train vehicle, the operating center of the second superconducting coil attached to the passenger car unit is located higher than the first superconducting coil attached to the bogie unit. It is composed.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In a magnetically levitated train vehicle according to the present invention, a passenger cabin 2 is levitated from a bogie unit 7 as shown in FIG. As means for this, a superconductor that is also used in a linear motor car is used.

A permanent magnet is installed on the carriage 7, and the cabin 2 is a high-voltage overhead wire 1 conventionally laid.
Power is supplied from B through the shoe 1A of the pantograph 1, and power is supplied to the superconductor. Also,
To stabilize the balance when the cabin unit 2 floats, the cabin unit 7
A gyro (there is a type using not only wheels but also a ferroelectric material) is used, and the attitude of the passenger compartment 7 is controlled by its output.

Further, it is necessary to reconsider the shape from the front end of the vehicle to the rear of the vehicle to control the flow of air during traveling. By reducing air resistance and causing air to flow into the space between the bogie unit 7 and the cabin unit 2 when the cabin unit 2 floats, the generation of buoyancy required for levitating can be achieved to stabilize the posture of the cabin unit 2. I will make it useful. Therefore, the passenger compartment 2 of the passenger vehicle is levitated by the electromagnetic force. Therefore, even if the flying height is small, it is possible to prevent vibrations and the like transmitted from the rails 9 through the wheels 6 from being directly transmitted to the passenger compartment 2 constituting the passenger vehicle.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings. In the present invention, in the operation of the passenger railway, the passenger compartment 2 is caused to travel with the passenger compartment unit 2 raised from the bogie unit 7 as shown in FIG.

When the vehicle stops at a station or the like, the ascent is stopped as described with reference to FIG. 1 and returned to a normal state. At the start of traveling, as shown in FIG. Power.
While the passenger cabin 2 floats during traveling, power is always supplied from the overhead wire 1B, but it is necessary to supply power from the overhead wire 1B even when the floating is completed. At this time, the active height of the pantograph 1 may need to be controlled because the total height of the vehicle differs between the time of ascent and the time of non-ascent. Further, in addition to the permanent magnet for floating, a permanent magnet having a different polarity is provided for pseudo connection of a passenger car and a bogie. However, in ascending the passenger car unit 2, the repulsive force of the same pole is used.

Here, the operation of the first embodiment of the present invention will be further described in detail with reference to FIG.

Power is supplied to the superconductor winding from the high-voltage overhead wire 1B through the pantograph 1 and its shoe 1A. The superconductor that has been supplied with electric power generates a magnetic force, and causes the passenger car unit 2 to float by reaction with the permanent magnet of the bogie unit 7.
At the start of traveling or at the time of traveling stop, it is expected that an absolute spatial position shift occurs between the bogie unit 7 and the passenger car unit 2. As a countermeasure, apart from buoyancy generating permanent magnets,
Prepare magnets of different polarity and attract them. Further, since the flying height at the time of flying is not large, connection with a wire or the like is also conceivable.

[0018]

The effect of the present invention is to improve the attitude control technology, and it can be applied to the development of a means of transportation having a levitation type of movement, which is because passengers Since the vehicle is a vehicle, the required posture stabilization has an effect that the technology can be established.
