The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

FIG. 1 is a cross-sectional view of a magnetic levitation system according to a first embodiment of the present invention, taken along a width direction.

1, the magnetic levitation system 101 according to the present embodiment includes a trajectory 120 installed in one direction and a bogie 110 moving on a magnetic levitation in the trajectory 120. [

The bogie 110 according to the present embodiment may be placed on the trajectory 120 or propelled from the trajectory 120. The orbit 120 is formed in a long direction in one direction and includes a girder 122 formed on the upper part and a column 121 disposed below the girder 122 and supporting the girder 122 from the ground.

On the lower surface of the girder 122, a floating-use ferromagnetic plate 173 is fixed and protrusions protruding downward are formed at both edges of the floating-use ferromagnetic plate 173. The projections are arranged to face the projections formed on the core 114a of the floating electromagnet 114 described below. A conductive plate 172 is disposed on the upper surface of the girder 122 and a conductive plate 172 is disposed opposite the propelling electromagnet 160.

The bogie 110 includes a bogie top plate 150 and a viewing frame 112 disposed below the bogie top plate 150 and four viewing frames 112 support the bogie top plate beneath the bogie top plate 150 do.

A bracket 113 protruding toward the facing view frame 112 is provided in the view frame 112. The bracket 113 is provided with a floating electromagnet 114 so as to face the floating ferromagnetic plate 173.

The floating electromagnet 114 includes a core 114a and a coil 114b installed to surround the outer periphery of the core 114a. The core 114a has a structure in which two projections are spaced apart with a groove therebetween, and a coil 114b is wound around the projections. The floating electromagnet 114 pulls the floating use ferromagnetic plate 173 against the floating use ferromagnetic plate 173, and thus a floating force is generated. The present invention is not limited to this, and the floating electromagnet 114 may be positioned on the upper side, and the floating-use ferromagnetic plate 173 may be positioned below the foil .

A protruding portion 112a protruding toward the opposing view frame 112 is formed on the upper portion of the view frame 112 and a propelling electromagnet 160 is fixed to the lower surface of the protruding portion 112a. The protrusion 112a is protruded from the side surface 112b of the view frame 112 toward the widthwise center of the track 120. [

The propulsion electromagnet 160 includes a core 161 and a coil 165 inserted in a groove formed in the core 161. [ A plurality of projections 163 are formed in the core 161 in the longitudinal direction of the track 120 and coils 165 are inserted into the grooves between the projections 163. [ Three coils 165 are provided and three coils 165 are alternately inserted into the grooves. Since the propulsion electromagnet 160 is installed to face the conductor plate 172, when the propulsion electromagnet 160 moves, a magnetic flux moving in time and space is generated, and an eddy current is generated in the conductor plate 172. The interaction between the eddy currents and the air magnetic flux is represented by Lorentz's force equation. When a linear induction motor is used as in the present embodiment, a plate-shaped conductor plate can be provided on the upper surface of the track on a track, thereby freeing the design of the track. In addition, it is possible to control the same as the alternator, and it is easy to generate large-output atmospheric power and it is easy to maintain.

On the inner side surface of the view frame 112, a guide roller 118 is provided to abut the side surface of the girder 122 in an emergency. The guide roller 118 supports the bogie 110 in an emergency so as to prevent the bogie 110 from swaying in the lateral direction.

Further, a plurality of dampers 152 are installed between the view frame 112 and the truck upper plate 150. The damper 152 may be a pneumatic or hydraulic damper and serves to buffer vibrations and shocks applied to the truck upper plate 150.

The view frame 112 is provided with an injection nozzle 130 for removing foreign matter. The end of the injection nozzle 130 is open toward the orbit 120. The injection nozzle 130 is fixed to the inside of the side surface of the view frame 112 and is inclined with respect to the inside of the side surface of the view frame 112. The injection nozzle 130 injects air, and the injection nozzle 130 is connected to a tank or an air compression pump that stores compressed air.

The open end of the injection nozzle 130 is disposed so as to face the upper surface of the conductive plate 172, and removes foreign substances located on the upper surface of the conductive plate 172. Since the conductive plate 172 is exposed upward, it is exposed to foreign substances such as sand, dust, and garbage. Snow may accumulate on the conductor plate 172, especially during winter. This foreign matter interferes with the operation of the gap sensor, so that the gap between the floating electromagnet 114 and the conductive plate 172 can not be kept constant. In addition, the foreign matter may be caught in the gap of the electromagnet or the like to cause mechanical defects.

FIG. 2 is a cross-sectional view of a magnetic levitation system according to a second embodiment of the present invention, taken in the width direction.

2, the magnetic levitation system 102 according to the second embodiment has the same structure as the levitation system according to the first embodiment except for the installation structure of the injection nozzle 140 So redundant description of the same structure is omitted.

The same structure as that of the floating system is provided, so redundant description of the same structure is omitted.

A plurality of propelling permanent magnets 175 are successively disposed along the longitudinal direction of the track 120. The propelling permanent magnets 175 are provided on the upper surface of the track 120. [ The propelling research magnets 175 are arranged so that the N poles and the S poles are alternately located. A propelling electromagnet 180 is mounted on the protrusion 112a of the view frame 112. The propelling electromagnet 180 includes a core 181 and a coil 182 surrounding the core 181.
