Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an inductive wheel and induced how to use this maglev is particularly useful when applied to a case of inducing the garage or the like maglev from mains.

[0002] Development of a linear motor car is being promoted as a next-generation transportation system. In this linear motor car, a superconducting magnet is mounted on a vehicle body side, and travels by interaction between a superconducting magnet and a ground coil which is an electromagnet arranged on the ground along a track (guideway).

[0003]

In a transportation system using a linear motor car as described above, it is necessary to construct a guidance system for guiding the linear motor car from a main line to a garage, a yard, or the like. In this case, it is theoretically possible to install a ground coil by installing a ground coil as in the case of the main line, but installing a ground coil only for guidance to a garage or the like is costly and practical. is not.

[0004] That is, development of a system for guiding a linear motor car, which cannot run on its own without a ground coil, without the ground coil is expected.

[0005] The present invention has been made in view of the above prior art, and an object thereof is to provide an inductive how induction vehicle and using it maglev.

[0006]

The structure of the present invention which solves the above-mentioned problem is such that the wheels are rotated by the driving of the drive unit so that the wheels can run on their own, and the right and left sides of the linear motor car straddle the vehicle body. A gate-shaped body having legs on both sides faces a propulsion magnet of the linear motor car, and a magnetic coupling force acts between the magnet and the magnet.
And having an electromagnet which is disposed on the inner surface of the leg like that.

Further, the induction vehicle and the linear motor car are magnetically coupled by utilizing the magnetic interaction between the electromagnet of the induction vehicle running with the electromagnet and the propulsion magnet of the linear motor car. In this state, the linear motor car is guided by causing the guided vehicle to run by itself.

[0008]

According to the present invention having the above-described structure, a force mediated by magnetism acts on the magnet of the linear motor car and the electromagnet of the induction car. The linear motor car runs along with the car.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG.
Is a front view thereof.

As shown in both figures, the linear motor car 1
Has superconducting magnets 2a, 2b on the left and right sides of its lower part, and has tires 3a, 3b for running without magnetic levitation during low-speed running (for example, running at 100 km / h or less). . At the time of guidance, of course, tire 3
a, 3b.

The guide vehicle 4 has a leg-shaped body 5 having legs 5a, 5b on both left and right sides and straddling the body of the linear motor car 1, and a leg portion facing the magnets 2a, 2b. And electromagnets 6a and 6b disposed on inner surfaces of 5a and 5b. Wheels 7a, 7b and hydraulic motors 8a, 8b are provided below the legs 5a, 5b.
The vehicle body 5 is configured to be able to run on rails 9a and 9b by rotating the b by hydraulic motors 8a and 8b.

The induction car 4 is a magnet 2 of the linear motor car 1
a, 2b and the electromagnets 6a, 6b
The number is determined in consideration of the traction force of the guided vehicle 4 and the number of vehicles of the linear motor car 1. The rails 9a and 9b are continuously laid on a main line having a guideway 10 provided with a ground coil (not shown). Thus, the linear motor car 1 traveling on the main line along the guideway 10 enters into the internal space formed by the vehicle body 5 of the guidance vehicle 4 waiting at the end of the guideway 10 and stops by inertia. . In order to prevent the magnetic flux of the electromagnets 6a, 6b from entering the rails 9a, 9b at the branch point of the rails 9a, 9b, it is necessary to make a contrivance such as forming the rails 9a, 9b in this portion with a non-magnetic material. .

In this embodiment, the vehicle body 5 straddles the vehicle body of the linear motor car 1, and the magnets 2a and 2b and the electromagnet 6
If the electromagnets 6a and 6b are excited in a state where the electromagnets 6a and 6b are opposed to each other, a magnetic force acts between the magnets 2a and 2b and the electromagnets 6a and 6b. Therefore, if the guided vehicle 4 is driven by itself in this state, the interaction between the guided vehicle 4 and the linear motor car 1 through the magnetic field also causes the linear motor car 1 to travel together with the guided vehicle 4 via the tires 3a and 3b. Move.

In order to properly guide the linear motor car 1, the magnets 2a and 2b and the electromagnets 6a and 6
Although it is possible to use the attraction force between b and the repulsion force, the relative positional relationship between the linear motor car 1 and the legs 5a and 5b of the guide car 4 is maintained constant. A guide plate (not shown) having a vertical surface is provided on each of the legs 5a and 5b, and a guide wheel in contact with the guide plate is disposed on the linear motor car 1 so as to be rotatable about a vertical axis.

Although the guide vehicle 4 is provided with a driver's cab 4a so that the driver 11 can ride and drive, the guide vehicle 4 is basically guided by unmanned driving under control from the ground.

[0017]

As described above in detail with the embodiments, according to the present invention, a linear motor car, which cannot run on its own without a ground coil, is connected by a magnetic interaction using a magnet. It is possible to guide freely by running a guided vehicle by itself. Therefore, a desired guidance system can be realized only by securing the traveling path of the guidance vehicle as ground equipment without providing a ground coil or the like for guidance.
