Description

  The present invention relates to a magnetically levitated vehicle.

As a traffic system for moving a vehicle by magnetically levitating, one using a superconducting (conducting) conductive magnet and one using a normal conducting magnet have been developed.
The former system is disclosed in Patent Document 1 below, and the latter system is disclosed in Patent Document 2.
Japanese Patent Laid-Open No. 06-255486 JP 09-123908 A

In a normally-conducting attraction type magnetically levitated vehicle, the propulsive force of the module (cart) is transmitted to the vehicle body via a sliding table by a traction link. The traction link is connected to a bracket attached to the module via a bolt. The rubber on the side of the bracket through which the bolt passes is filled with cushioning rubber so that the module vibration is not transmitted to the vehicle body as much as possible.
Also, an aluminum washer is inserted between the bolt head and nut and the bracket to reduce the surface pressure.
However, there was a problem that the bracket and the washer were rubbed and worn due to module vibration, and the washer was useless for several years.
An object of the present invention is to provide an improved traction link for connecting a bogie (module) and a vehicle body of a normal conducting attraction type magnetic levitation vehicle.

  The normal conducting attraction type magnetically levitated vehicle according to the present invention is supported as a basic means by a plurality of modules having normal conducting magnets arranged opposite to the lower surface of the rail, and a suspension through the modules. A normally-conducting attraction type magnetically levitated vehicle equipped with a vehicle body, comprising a traction link that connects the module and the vehicle body, and a bracket that connects the traction link to the module is free to connect the bracket at the end of the traction link to the bracket A joint and a washer made of Teflon material disposed on a bolt / nut portion for joining the metal fitting and the bracket are provided.

  According to the present invention, a stable magnetic levitation traveling can be achieved by connecting a bogie (module) and a vehicle body of a normal conducting attraction type magnetic levitation vehicle.

FIG. 1 is an explanatory view showing the appearance of a magnetically levitated vehicle embodying the present invention, and FIG. 2 is a side view.
In this embodiment, one train is composed of three vehicles 1A, 1B, and 1C and travels on the track 2.
Each vehicle includes a module 20 corresponding to a carriage at the lower part thereof. A total of ten modules 20 are installed, five on each side of each vehicle.

FIG. 3 is an explanatory diagram showing the relationship between the electromagnets provided in the module 20 and the track 2.
The track 2 includes sleepers 5 placed on a base 3 made of concrete or the like, and rails 6 fixed to both sides of the sleepers 5. The rail 6 is made of a magnetic material and has convex portions 6a and 6b that protrude downward in an eight-letter shape.
A reaction plate 7 of a linear motor for propulsion is attached to the upper surface of the rail 6.

On both sides of the base 3, power transmission lines 4 are disposed via support columns 4a.
The module 20 has an electromagnet core 30 around which a coil 32 is wound. The pantograph 34 in contact with the power transmission line 4 receives power and sends current to the coil 32.
The module 20 is attracted toward the rail 6 by the magnetic force generated in the core by the current flowing through the coil 32 and floats in the direction of arrow B.
The flying distance is set to about 8 mm. The gap sensor 60 monitors the flying distance and controls the current value sent to the coil 32 so as to keep the flying distance constant.

On the both sides of the core 30, upward convex portions 30a and 30b are provided. When the protrusions 30a and 30b of the core 30 and the protrusions 6a and 6b of the rail 6 face each other, a force that always returns to a normal position is generated even when the vehicle body 10 moves in the arrow A direction.
A linear motor coil 40 is mounted on the lower surface of the module 20 to generate a propulsive force of the vehicle between the reaction plates 7 fixed to the upper surface of the rail 6.
A support device 50 is provided on the lower surface of the module 20 to support the vehicle on the rail 6 while the levitation is not performed.
The module 20 supports the vehicle body 10 via the air spring 12.

FIG. 4 shows a connection structure of ten modules 20, and each module 20 is connected via a slide base 70.
A second slide 70b disposed between the first and second modules in the traveling direction of the vehicle indicated by the arrow F, and a fifth slide disposed between the fourth and fifth modules. The moving base 70e is connected to the vehicle body 10 side. The other slides are connected by a link denoted as a whole by 80.

FIG. 5 is a plan view of the module assembly in which the left and right modules 20 are assembled, and FIG. 6 is a front view of the module assembly.
Since the posture of the module 20 is not stable as a single unit, a pair of left and right modules 20 are opposed to each other, and front and rear ends are connected by a module connecting link 100 to constitute an assembly.
The connecting link 100 includes an upper link member 110 and a lower link member 120, and both link members are coupled by pins 130.

  At the top of the module 20 is provided a traction link 300 that connects the module and the vehicle body, and an emergency roller 500 that supports the module 20 when the magnet of the module 20 is obstructed and the levitation force due to magnetic force disappears. Is also equipped.

7 is a front view of the module, FIG. 8 is a plan view, FIG. 9 is a right side view, and FIG. 10 is a view of the module from the back side.
The module denoted as a whole by reference numeral 20 includes a frame 200, a traction link 300 attached to the upper portion of the frame 200, and a magnet coil unit 250 attached to the lower portion of the frame.

As shown in FIG. 9, the frame 200 has a magnet core 220 connected to the upper frame 210 via an end box 230 and a magnet mounting bracket 240, and is configured by a magnet coil 250 attached by the magnet core 220. .
The module 20 is equipped with a service brake 400, an emergency roller 500 that protrudes by hydraulic pressure in an emergency and supports the vehicle, and a support skid device 600 that becomes a support member when the vehicle is stopped on the rail by stopping magnetic levitation. Is done.

FIG. 11 is an explanatory view showing the attachment structure of the traction link, FIG. 12 is an explanatory view of the traction link alone, and FIG. 13 is an explanatory view showing the attachment structure of the traction link and the module side.
One end side of the tow link 300 is connected to the upper frame 210 of the module via a bracket 310 on the module side. The other end side of the traction link 300 is connected to the vehicle body 10 side via a bracket 350.
The traction link 300 has a pipe-shaped main body, and mounting brackets 301 and 302 are fixed to both ends by welding.

It has a tow link that connects the module and the car body,
The bracket that connects the traction link to the module includes a universal joint that connects a metal fitting at the end of the traction link to the bracket, and a washer made of Teflon material that is disposed on a bolt / nut portion that connects the metal fitting and the bracket.

  In the present invention, a washer 330 made of Teflon is provided between the guide ring 324 and the mounting portion 312. By interposing the Teflon washer 330, friction between the aluminum guide ring 324 and the mounting portion 312 is reduced, and wear of the guide ring 324 is prevented.
