DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic levitation type railway vehicle propulsion device.

[0002]

2. Description of the Related Art A conventional magnetic levitation railway using a superconducting coil on a vehicle will be described with reference to FIG.

A vehicle 1 of a magnetic levitation railway has a vehicle body 3 mounted on a bogie 2, and furthermore, a vehicle levitating, guiding,
The superconducting coils 4 and 4 for propulsion are mounted, and the vehicle interacts with the ground coils 7 and 7 on the side wall 6 of the track 5 to levitate, guide, and propell the vehicle.

However, the vehicle rather than flies constantly during running of such stop longitudinal and vehicle base is the track 5 at a low speed by the driving wheels 8, 8 and the guide wheels 9, 9 provided in the lower portion of the carriage 2 There is a wheel traveling area that travels along the ground along the road.

As described above, the track 5 in the superconducting magnetic levitation railway has a levitation coil 11 for levitation of the vehicle 1.
Its side walls 6 a propulsion coil 10 for driving the train and
In addition to driving the vehicle 1 in preparation for, the vehicle also plays a role of a traveling track of the traveling wheels 8 and 8 and the guide wheels 9 and 9 when traveling on the ground as needed.

[0006] In order to install the propulsion coil 10 and the levitation coil 11 (both are collectively referred to as ground coil 7), the track side wall 6 has a thickness of about 600 to 700 mm, and the coil is formed on the ground coil mounting surface side. It is a concrete structure pre-molded into a shape that is easy to install. The propulsion coil 10 and the levitation coil 11 are attached to the track side wall 6, and the guide wheels 9 protruding from the vehicle side are in contact with the concrete guide surface 12 to prevent the vehicle 1 from contacting the track side wall 6 .

[0007] In a train depot or the like, the train is supported by the running wheels 8 and runs at a low speed, so that the floating coils 11 and
11 is unnecessary. However, the propulsion coils 10 and 10 are necessary, and the raceway side wall 6 for mounting the propulsion coils 10 and 10 is required.

[0008]

However, in the track of a magnetically levitated railroad using superconductivity configured as described above, it is necessary to provide a track branching device for branching the track. The branching device in this case includes a side wall vertical moving branch and a traverser branch. However, since the track side wall moves up and down and left and right, the device becomes complicated and large-scale. Further, in a place such as a vehicle depot, the width of the track side wall on both sides is added to the vehicle width as a required track width, so that the interval between adjacent service lines is increased and the area of the vehicle depot is increased. Furthermore, at the train depot, the bogies before train departure and other maintenance inspections are carried out, so workability is poor if there is a track side wall, and furthermore, work such as excitation and demagnetization of superconducting coils cannot be performed. There is.

In view of the above, the present invention removes the side wall of the track, and can easily configure the branching structure of the track, thereby making it possible to reduce the interval between the lead-in lines. It is intended to facilitate the workability of vehicle maintenance and inspection. Therefore, an attempt is made to achieve this by improving the method of installing the propulsion electromagnetic coil at low speeds.

[0010]

Means for Solving the Problems] The present invention in a wheel travel area for low-speed running of a vehicle or the like base, below the electromagnetic <br/> coil mounted on the vehicle to the corresponding propulsion electromagnetic coil thereto, without touching the running wheels of the truck, water earnestly or is inclined to face at right angles to the flux installed in the track floor. Also, the propulsion electromagnetic coil is replaced with the vehicle-side electromagnetic coil.
It is installed at the position where the interaction with the maximum.

Further, without providing the track side wall in the wheel traveling area, constitutes a planar orbit of only promote the electromagnetic coil of the orbit floor, bifurcation of the guide track is constituted by a simple head-shaking switch rail .

[0012]

With such a configuration, there is no side wall and the electromagnetic coil for propulsion on the floor of the miniaturized track is mounted on the vehicle side .
Due to the mutual force with the electromagnetic coil , the vehicle runs on wheels at low speed. The bifurcation of the guide track is a simple neck vibration switched of, the small branch device.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS.

In a low-speed wheel running area such as in a depot, the magnetically levitated vehicle does not levitate and travels on the track while being guided by the guide wheels 9 and 9 .

In such a case, in FIGS. 1 and 2, the superconducting coil 4 which is an electromagnetic coil mounted on the bogie 2 of the vehicle 1
Respect, the propulsion electromagnetic coil 14 on the track floor on 13 thereunder, a horizontal distance from the center of the superconducting coil 4 to the center of the propulsion electromagnetic coil 14 (d), about the outside of the vehicle 1 0.30 Displace horizontally by 0.35 m. At this time, naturally, the conventional track side wall is not provided.

The value of the horizontal distance d that 0. 30～0.35M This is read from the mutual force characteristic curve (Fig. 3).

[0017] That is, FIG. 3, the vertical displacement of the propulsion electromagnetic coil 14 centered position with the superconducting coil 4 center position (distance h), Ri by the positional relationship between the horizontal displacement (distance d) <br The changing propulsion force (Fkg) is shown. Sand
Chi, Figure 3 is a driving force characteristics acting upon flowing the reference current to the electromagnetic carp <br/> Le 14 for promotion by the positional relation of the deviation
It is a figure showing a change .

[0018] According to this, the positional relationship which can be obtained than necessary thrust Fkg for moving the vehicle 1, propulsion electromagnetic coil 14 becomes larger closer to the center of the superconducting magnet in the vertical direction (h). In the horizontal direction, it can be seen that the maximum position is approximately 0.30 to 0.35 m shifted symmetrically from the position of d = 0.

The propulsion electromagnetic coil 1 is provided outside the vehicle 1.
To place a 4 and 14, since the draft within vehicle wheel 9, 9 and the guide rails 12, 12 is adjacent to the line wheels 8, 8 run,
This is to avoid interference with this, and also to take into account the workability of maintenance and inspection on the service lines.

As another embodiment of the present invention, as shown in FIG. 4, the propulsion electromagnetic coil 14 is an electromagnetic coil on the vehicle 1 side.
Rather than below the certain the superconducting coils 4, outside the vehicle 1,
They may be arranged at right angles to the direction of the magnetic flux.

As described above, when the height of the propulsion electromagnetic coil is increased, the magnetic flux density increases, so that the obtained propulsion force also increases. However, in this case, in terms of reducing the size of depots and construction cost gowns, and simplifying the branch structure,
It is slightly inferior to the previous embodiment.

Next, a description will be given of a track branching device using the above-described electromagnetic coil for propulsion according to the present invention (see FIG. 5).

Compared to the conventional branching device having a track side wall, the branching swing rail 18 integrated with the propulsion electromagnetic coil 14 arranged on the track floor is simply moved.

That is, from the straight path 16 to the branch path 17
However, it is composed of a swing branch rail 18 that is shared by both, and an escape straight rail 19 and an escape branch rail 20 on the straight side and the branch side, respectively.

The swing branch rail 18 rotates about the fulcrum 21 and serves as both a branch and a straight (two-dot chain line) rail. In this case, the displacement of the propulsion electromagnetic coil 14 due to the arrangement along the branch curve with respect to the straight line of the straight traveling rail is within a range that hardly affects the propulsion force.

Escape straight rail 19 and escape branch rail 20
Is a fulcrum 2 depending on the presence or absence of the swinging-off branch rail 18, respectively.
It moves around 2 and 23 and replaces it.

[0027] According to the present invention, for the promotion of dedicated as described above
By arranging the track floor of the electromagnetic coil, the track branching structure can be easily configured, and the distance between the lead-in lines can be narrowed, so that the depot can be made compact and the construction cost can be reduced. It will also lead to improvement in sex.

[0028]

According to the present invention, by having established a dedicated propulsion electromagnetic carp <br/> Le of the orbit floor, in the wheel travel area of the low-speed running, it is possible to remove the track side walls, Ma
In addition , the track branching structure can be easily configured, and the distance between the service lines can be narrowed.
The construction cost can be reduced, and the maintenance and inspection of the vehicle can be facilitated.
