Inside the both coil mounting tracks b, a first propulsion coil e and a second propulsion coil f are respectively arranged in a row in the longitudinal direction of the coil mounting track b. When the coil f is energized, the coil f is magnetically levitated by the electromagnetic induction action of the superconducting magnet m and the coils e and f, which will be described later, and a thrust force is added to the vehicle so that the vehicle travels at high speed.

On the other hand, between the two coil mounting tracks b,
A trolley g is provided, and a pair of front and rear traveling wheels h are provided below the trolley g so as to roll on the wheel track d. A pair of front and rear guide wheels i are horizontally provided on both sides of the carriage g so as to roll on the inner wall surfaces of the upper portions of the coil mounting tracks b. j is installed via each air spring k. Further, superconducting magnets m are provided on both sides of the carriage g where the first propulsion coil e and the second propulsion coil f are located, facing the first propulsion coil e and the second propulsion coil f. When the first propulsion coil e and the second propulsion coil f are energized, the carriage g is magnetically levitated by the electromagnetic induction action of the first propulsion coil e and the second propulsion coil f and the superconducting magnet m, and the thrust is generated. In addition, the vehicle runs at high speed.

Therefore, the above-mentioned magnetic levitation vehicle drives the traveling wheels h and travels while rolling on the upper inner wall surfaces of the coil mounting tracks b by the guide wheels i when traveling in the station yard. .

[0007]

However, since the coil mounting track b in the above magnetically levitated vehicle is configured to surround both sides and the lower part of the carriage g, maintenance of the traveling wheels h and the guide wheels i is performed. Not only is it troublesome to perform tire inspection and tire replacement due to tire wear, but also when the vehicle travels at high speed, the traveling wheels h and the guide wheels i are stored in the carriage g. In order to cool the vehicle, the installation space of the cooling device installed in the carriage g is limited, and maintenance and inspection of these are difficult.

On the other hand, since the above-mentioned magnetic levitation vehicle is provided so as to store the traveling wheels h and the guide wheels i in the carriage g, the carriage is used for the storage device for the traveling wheels h and the guide wheels i. There is a problem that the weight of the vehicle itself becomes heavy, and the result is against the weight reduction of the magnetically levitated vehicle.

In order to solve the above-mentioned problems, the present invention eliminates the limitation of the installation space of the cooling device for the superconducting magnet, facilitates maintenance and inspection, and reduces the weight of the vehicle itself. The purpose is to provide a levitating vehicle.
