DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail-car variable bogie capable of changing the rail gauge of a rail car.

[0002]

2. Description of the Related Art Conventionally, when the gauge of a track changes between a departure place and a destination, a train change (for example, a change from a Shinkansen to a conventional line) or a change in the same vehicle is performed on the track side. I am trying to do it. For example, on the Yamagata Shinkansen, the gauge of the conventional line is changed to the same as that of the Shinkansen.

[0003] In Europe, there is an example corresponding to a case where the gauge of a track changes with a single-axis independent accompanying truck.
That is, in this case, the bogie has one axis, and all bogies have an independent structure. Furthermore, there is an example in which a bogie is converted every time.

[0004]

However, in the above-mentioned conventional system for changing trains, passengers have to change trains, which is inconvenient and takes time. Also, changing the trajectory is enormously expensive. Furthermore, in the case of a single-axis independent accompanying truck, the structure cannot be used as a driving truck.

When a bogie is converted, a large number of ground facilities are required for exchanging the bogie, which requires a large space and increases equipment costs. The present invention eliminates the above-mentioned problems, eliminates the inconvenience of passenger transfer, can reduce time, reduce costs, can use existing tracks, and has a simple structure, It is an object of the present invention to provide a rail-gauge variable bogie for a railway vehicle in which a compact driving motor is integrated with wheels and a rail-gauge can be easily changed.

[0006]

According to the present invention, in order to achieve the above object, there is provided a rail-car-ranged variable bogie capable of changing the rail-to-rail distance of a railcar, having a lock hole and a non-rotating axle; A bushing-shaped slide shaft slidable in the axial direction, having two lock through-holes formed coaxially with the axle and formed in the axial direction and the vertical direction, and a bearing mounted on the slide shaft through a bearing. The first drive from the drive unit and the wheels mounted thereon can be fitted and locked in the lock hole of the axle and the first lock through hole of the slide shaft, and can be locked by the second drive from the drive unit. A lock pin that is at least disengaged from the lock hole of the axle and is lockable by being fitted into the lock hole of the axle and the second lock through-hole of the slide shaft, and controls the axial movement of the slide shaft. A lockable device, a cylindrical rotor having one end fixed to the side surface of the wheel and the other end supported on the slide shaft via a bearing, and corresponding to the cylindrical rotor. A driving motor having a stator fixed to the slide shaft, the slide device is slid by the operation of the lock device to move the wheels in the axle direction, and fixed at a predetermined position, so that the track distance is increased. Is changed so that it can run on tracks between different gauges.

[0007]

According to the present invention, since the configuration is as described above,
By changing the position of the wheel and the slide shaft on which the drive motor integrated with it is mounted by the operation of the drive device, passengers do not need to transfer even if the track gauge changes, and passengers need to transfer. Can be eliminated and time can be reduced. Also, since there is no need to change the orbit,
Costs can be reduced and existing tracks can be used.

Furthermore, a compact driving motor having a simple structure is mounted on the slide shaft integrally with the wheels, so that the work for changing the gauge can be easily performed.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view of a rail-to-rail variable bogie showing a first embodiment of the present invention.
In this figure, reference numeral 1 denotes an axle, which is fixed to a bogie frame 3 via an axle spring 2 so as not to rotate.

On the left and right sides of the axle 1, bushing-like slide shafts 4 are arranged coaxially with the axle 1 and slidable in the axial direction. Wheels 6 are attached to the slide shaft 4 via bearings 5, and the wheels 6 are configured to be rotatable on a track 13. Its wheels 6
A cylindrical rotor 8 having one end fixed to the inner surface of the shaft and the other end supported by the slide shaft 4 via a bearing 7.
And a drive motor 11 corresponding to the cylindrical rotor 8 and including a stator 10 having an armature coil 9 fixed to the slide shaft 4. That is, the structure is such that the wheel 6 and the driving motor 11 are mounted on the slide shaft 4.

The slide shaft 4 is arranged in the axial direction with respect to the axle 1,
In other words, it is configured to be slidable in the left-right direction, and when the track 13 of the track is in a narrow section, the slide shafts 4 are respectively slid inside the axle 1 so that the distance between the left and right axles is reduced. That is, the slide shaft 4 is configured to be fixed by the lock device 12 at the changed position.

FIG. 2 is a cross-sectional view of a main part of the rail-carriage variable trolley showing a specific example of the part A in FIG. 1, and FIG. 3 is a side view of the rail-car variable trolley. As shown in these figures,
Axle 21 fixed to bogie frame 23 via axle spring 22
On the upper side, a bushing-like slide shaft 24 that is arranged coaxially with the axle 21 and that can slide in the axial direction is arranged. Wheels 26 are attached to the slide shafts 24 via bearings 25 composed of roller bearings, and the wheels 26 are configured to be rotatable on a track 37.

One end is fixed to the inner surface of the wheel 26 and the other end is supported by the slide shaft 24 via a bearing 27 formed of a ball bearing. In correspondence with child 28,
A driving motor 31 including a stator 30 having an armature coil 29 fixed to the slide shaft 24 is provided. That is, the structure is such that the wheel 26 and the driving motor 31 are mounted on the slide shaft 24.

One end of a case-like rotating member 45 constituting the cylindrical rotor 28 is attached to the wheel 26 with a bolt 40. Here, an example of the lock device will be specifically described. The electromagnetic lock device 32 is attached to the vehicle bearing 38 by the fixture 36. This electromagnetic lock device 32 has an electromagnetic coil 33 for operating a lock pin 34. That is, when the electromagnetic coil 33 is deenergized, the lock pin 34 is pushed up by the spring 35 to be locked, and the lock pin 34 is lowered when the electromagnetic coil 33 is energized.

The slide shaft 24 has a stepped portion on the outer surface of the wheel 26 so as to be thicker at both ends, and a first portion of the slide shaft 24 is provided behind the thickened slide shaft 24.
Lock through hole 24a and second lock through hole 24b
Are formed. On the other hand, the axle 21 has a lock hole 21a.
In FIG. 2, in a solid line state, the lock pin 34 penetrates through the first lock through hole 24 a and is fitted into the lock hole 21 a of the axle 21 to be locked.

Therefore, when releasing the lock, the electromagnetic coil 33 is urged to lock the lock pin 3 against the spring 35.
4 is lowered to release the lock pin 34 from the lock hole 21a and the first lock through hole 24a. In this state, for example, the slide shaft 24 is slid by rotating wheels on a track extending from a standard gauge distance of 1435 mm provided in a section where the gauge distance is to be variable to a narrow gauge distance of 1067 mm.

Therefore, as shown by the dotted line in FIG. 2, when the slide shaft 24 slides to the narrow gauge of 1067 mm, the electromagnetic coil 33 is deenergized, the lock pin 34 is raised by the spring 35, and the lock pin 34 is The lock is performed by fitting the lock through-hole 24b and the lock hole 21a. In the above embodiment, the electromagnetic lock device is arranged below the slide shaft, but may be arranged laterally or above the slide shaft.

Further, the electromagnetic lock device may be constituted by a fluid operated lock device. That is, the lock pin may be driven by a fluid. In this case, as described above, in the case of an electromagnetic lock, it is dangerous if the lock is released due to a failure of the electric system or the like. It is desirable to have a simple configuration.

It is desirable that the fluid-operated lock device be so configured as to provide a so-called fail-safe so that the lock is not released even if the pressure or oil pressure is released. Thus, the wheels 26 and the driving motor 31 mounted on the slide shaft 24 are slid inward from the outside and fixed. That is, as shown by the dotted line in FIG. 2, the gauge can be changed to a narrow gauge of 1067 mm.

With this configuration, it is possible to easily change the gauge of the bogie and to enable the same vehicle to travel on a track between different gauges. FIG. 4 is a schematic cross-sectional view of a rail-to-rail variable bogie showing a second embodiment of the present invention. In this embodiment, the driving motors arranged on the left and right are connected to be integrated, and the other points are the same as those of the first embodiment. The same reference numerals as in the embodiment are used, and the description is omitted.

A spline gear 51a is provided outside the case-shaped rotary member 50 forming the rotor 8 of the right drive motor 11, and a case shape forming the rotor 8 of the left drive motor 11. The spline gears 51b are arranged on the outside of the rotating member 50, and the spline gear device 51 is configured such that they are in shallow engagement.
In other words, they are configured to rotate integrally in the rotation direction, but to be slidable in the axle direction.

Therefore, the standard gauge 1435 shown in FIG.
When the gauge is changed from 10 mm to a narrow gauge of 1067 mm, the lock is released and the left and right slide shafts 4 are slid inward and fixed to obtain a narrow gauge of 1067 mm.
The gauge can be changed. In this case, the ends of the spline gear 51a and the end of the spline gear 51b of the spline gear device 51 come close to each other, forming a deep connection.

In the above embodiment, an example is shown in which a spline gear is formed outside the case-shaped rotating member.
The structure is not limited to this, as long as the wheels and the drive motor can slide in the axle direction, and the wheels and the drive motor on both sides are integrally driven in the rotation direction. Next, the number of axes of the rail-to-rail variable bogie of the present invention will be described.

FIG. 5 is a schematic plan view showing a one-axis rail-to-rail variable bogie. In the case of the bogie 60, slide shafts 62 are provided on the left and right of a single axle 61, and wheels 63 and a driving motor 64 are arranged on the slide shaft 62. And, although not shown,
Each slide shaft 62 is provided with a lock device.

FIG. 6 is a schematic plan view showing a two-axle rail-to-rail variable bogie. In the case of this bogie 70, two axles 71 and 75 are arranged, slide shafts 72 are provided on the left and right sides of the axle 71, wheels 73 and a driving motor 74 are mounted on the slide shaft 72, and the other axle is provided. A slide shaft 76 is also provided on the left and right sides of the wheel 75, and a wheel 77 and a drive motor 78 are mounted on the slide shaft 76. Although not shown, each of the slide shafts 72 and 76 is provided with a lock device.

Further, the number of axes of the rail-to-rail variable bogie for railway vehicles is not limited to the above-mentioned one axis and two axes, but may be three or more axes. Further, the structure of the driving motor and the arrangement of the wheels and the driving motor in the above embodiment,
The number of shafts or the structure of the lock device is not limited to the above embodiment, and various modifications can be made based on the gist of the present invention, and these are not excluded from the scope of the present invention.

[0027]

As described above in detail, according to the present invention, the position of the slide shaft on which the wheels and the driving motor integrated with the wheels are mounted is changed by the operation of the driving device. Even when the gauge of the track changes, the passenger does not need to change trains, eliminating the inconvenience of changing passengers and shortening the time.

Further, since it is not necessary to change the track, the cost can be reduced and the existing track can be used effectively. Furthermore, a compact driving motor having a simple structure is integrated with the wheels and mounted on the slide shaft, so that the work of changing the gauge can be easily performed.
