[0003]

2. Description of the Related Art In a general vehicle, the gauge of wheels of a bogie supporting a vehicle body is always kept constant corresponding to the gauge of a track, and it is impossible for the same vehicle to get on a track of a different gauge. . For example, on a Shinkansen, a vehicle runs on a wide gauge (wide gauge) rail, and on a conventional line, a vehicle runs on a narrow gauge (narrow gauge) rail.

The prior art includes the following.

[0005] The so-called regauge, in which the gauge of the wheel of the vehicle is kept as it is and the gauge of the track is modified to match the gauge of the wheel, is used to enter a section having a different gauge.

[0006] TALGO in Spain
There is a "train" variable gauge bogie. This bogie is composed of independent wheels supported on a bogie frame with an axle that can slide in the left-right direction, lock pins for positioning wheel gauges, and the like. It consists of a guide rail for guiding the position of the wheels. And the change of the gauge of the bogie is that the body support rail contacts a part of the bogie frame, supporting the weight of the car body and at the same time the wheel becomes no load, the lock pin is removed, and the wheel can slide in the left and right direction The wheel is moved to a new position by the guide rail, the lock pin is inserted, the wheel is positioned, the bogie descends from the vehicle body support rail, and the change of the wheel gauge is completed.

There is a bogie described in JP-A-54-47221. In this bogie, the wheels are freely rotatable before and after a pair of left and right independent plate-shaped bogie frames, and a rack is provided on a lower surface on both sides of a lower bar supporting the vehicle body via a spring member in a rail width direction. At the same time, a rack meshing with the rack is provided on the upper surface of the central portion of the bogie frame in the width direction of the rail. The bogie gauge is changed by lifting the lower surface on both sides of the lower bar with a belt conveyor and lifting it off the rack, and moving the lower bar along with the vehicle body as the wheels of the bogie frame travel, while gradually changing the gauge. The distance between the wheels along with the bogie frame is changed by the rails, and when the bogie has completely moved onto the rail of the final target gauge, the rack part of the lower bar lifted by the belt conveyor is placed on the rack of the bogie frame. This is done by positioning.

[0008]

However, the above-mentioned prior art has the following problems.

[0009] When changing the gauge of a track: Remodeling of track equipment requires enormous cost, labor and time. Since the wheel gauges have not changed, you will not be able to get into sections with different gauges after all.

[0010] In the case of a "Talgo train": When the gauge is changed, the wheels cannot move by themselves because they are separated from the rails. Therefore, the gauge conversion operation cannot be performed unless the driving force of the train is externally applied.

[0011] In the case of Japanese Patent Application Laid-Open No. 54-47221: Since the vehicle body is lifted by a belt conveyor on a bogie frame,
Very little weight on the wheels. For this reason, the adhesive force required for self-traveling is lost, so that it is difficult to employ a driving bogie that drives wheels. In addition to the case where the vehicle body is lifted on the bogie frame, the bogie frame may fall during traveling. Further, it is difficult to make the moving speeds of the bogie frame and the lower bar coincide when changing the gauge.

The present invention has been made in view of the above points, and it is possible to realize the wheel gauge conversion even with a self-propelled driving bogie, and at the same time, the same mechanism can be applied to an associated bogie, and running stability can be improved. no less a truck of a conventional gauge fixing system, eliminating the mechanism that moves from the ground equipment, maintenance is intended to provide a gauge changing and variable gauge base cars, as well as gauge changing facilities easy carriage.

[0020]

According to the bogie gauge changing method of the present invention having the above configuration (claim 1), for example, when the bogie moves from a narrow gauge track to a wide gauge track, before the bogie enters the relay track. Then, a part of the vehicle load acting on the side beam orthogonal to the side beam is pushed up through the auxiliary wheel, and the locking means that restrains the position of the tip of the side beam and the side beam is released. The positioning is released by holding the lock. This state is maintained until the bogie is completely transferred from the narrow gauge track to the wide gauge track with the relay track in between. During this time, the wheels on both sides of the axle slide outward according to the change in the distance between the rails, and at the same time, the side beam supporting each wheel moves outward with the wheels relative to the other side beam. And finally, the interval between the left and right wheels of the bogie expands until it becomes equal to the interval between the rails of the wide gauge track, and the interval between the left and right side beams constituting the bogie frame also expands according to the widening of the wheel interval. . In this state, the vehicle load that has been pushed up via the auxiliary wheels again acts on the tip of the side beam, and the relative position of the side beam and the side beam in the left-right direction is again locked by the locking means. It is held and positioned. As a result, the distance between the left and right bogie frames and the distance between the left and right wheels of the bogie are kept constant, and the bogie can run stably on a track with a wide gauge. Note that when the bogie is shifted from a wide gauge track to a narrow gauge track, the gauge of the bogie is changed by substantially the same operation as described above.

Therefore, according to the bogie gauge changing method of the present invention, the unlocking operation of the mechanism that locks the wheel gauge is performed as follows.
This is performed by using a part of the forward moving force of the bogie to push up an auxiliary wheel provided on the bogie, and requires no special power for unlocking. When the wheel slides to a new position, it uses a part of the forward movement of the bogie to convert the gauge by pressing the wheel with the interaction force with the track rail or guide rail, and special power is required. do not do. The locking force of the wheel gauge is generated when the auxiliary wheel comes off the traveling path and a vehicle load is applied. The bogie passes through the variable gauge section
To do this, the bogie is usually equipped with a motor for running the vehicle.
Axle load is applied even during the gauge conversion,
The wheel does not rise, so it is on the common rail
The wheels and races remain the same during the gauge conversion
Can self-propelled with the adhesive force of

According to the variable gauge bogie of the present invention having the above configuration, the wheel interval of the bogie is changed according to the change in the rail interval corresponding to the ground equipment ( see the embodiment ). At this time, the left and right lateral beams move relative to the other side beam via the left and right link members in a direction opposite to each other while maintaining a constant interval and a parallel relationship, and the left and right side beams maintain the parallel relationship. Approach or separate relatively. Thus, the method of changing the gauge of the bogie is reliably performed.

In the variable gauge bogie according to the third aspect, when the gauge of the wheel is changed, the leading end side of the cross beam of the bogie frame is lifted with respect to the other cross beam via the auxiliary wheel, and the two are moved in the left-right direction. The restraining state by the locking means positioned by is released. This allows the wheels on both sides of the axle to
It slides at the same time as the bogie frame crosses according to the change of the track gauge. At this time, a part of the vehicle load acting on each link member is also supported by the auxiliary wheels, and is supported at three points, the front and rear wheels on one side and the auxiliary wheel at the intermediate position, so the load acting on each wheel decreases. And each wheel can slide smoothly. Also, when the wheel gauge changes in accordance with the change in the track gauge corresponding to the ground equipment, the drive device of each axle is held in the corresponding bogie frame.

In the variable gauge cart according to the fourth aspect, the slide is performed by substantially the same operation as the cart according to the third aspect, but the position at which the auxiliary wheel lifts the lateral beam is closer to the leading end of the side cart than the cart according to the third aspect. Therefore, the lifting of the side beam is performed more smoothly.

In the variable gauge cart according to the fifth aspect, the lever member is tilted about the pivot point by the auxiliary wheel, and one end of the link member is lifted together with the lock pin, thereby restraining the side beam and the side beam by the lock pin. The relationship is broken.

In the variable gauge cart according to the sixth aspect, since the left and right wheels can rotate freely, the running stability on a straight road is excellent.

In the variable gauge cart according to the seventh aspect, since both the left and right wheels are fixed with respect to the rotation of the axle, there is no difference from the behavior of the conventional wheel.

According to the gauge changing equipment of the present invention having the above-mentioned structure (claim 8), it is constituted by the rail and the traveling path, and has no movable parts. When the vehicle travels from a wide gauge track to a narrow gauge track, the rails serve to press the wheels.

According to the gauge changing equipment of the ninth aspect, it is constituted by the rail, the traveling path, and the inner guide rail, and has no movable part. When the vehicle travels from a narrow gauge track to a wide gauge track, the inner guide rails serve to press the wheels.

According to the gauge changing device of the tenth aspect, it is constituted by the rail, the traveling path, and the outer guide rail, and has no movable part. When the vehicle travels from a wide gauge track to a narrow gauge track, the outer guide rails serve to press the wheels. In addition, since the force for pressing the wheel can be relatively larger than the case of only the rail in the gauge changing equipment of claim 8, only the rail can be used.
The section of the relay track can be made relatively shorter than the gauge changing equipment (claim 8).

According to the gauge changing device of the eleventh aspect, it is constituted by the rail, the traveling path, the inner guide rail, and the outer guide rail, and has no movable part. Vehicles can also travel from narrow gauge tracks to wide gauge tracks.
It is also possible to travel from a wide gauge track to a narrow gauge track, and when traveling from a narrow gauge track to a wide gauge track, the inner guide rail presses the wheel and the narrow gauge track travels from the wide gauge track. When traveling to the outside, the outer guide rail serves to press the wheels.

The gauge changing equipment according to the twelfth aspect corresponds to the bogie according to the third and fifth aspects in which the auxiliary wheels are located inside the rail, and the gauge changing equipment according to the thirteenth aspect has the auxiliary wheels positioned outside the rail. It corresponds to the truck according to claim 4 located.

As is apparent from the above description,
Gauge change methods and variable gauge table car truck of the present invention
The, it has the following effects.

(1) According to the gauge changing method of the present invention, the gauge can be converted by running the bogie itself without separately applying a driving force. In addition, the gauge can be changed reliably while passengers and luggage are loaded, the running performance after changing the gauge is as stable as that of the conventional fixed type, and the ground equipment can be simple in structure.

(2) According to the variable gauge trolley of the present invention, the same configuration can be applied to an auxiliary trolley without a driving device. Therefore, the drive bogie can be easily converted into the auxiliary bogie or the auxiliary bogie into the drive bogie, and can be applied to any of passenger cars, electric cars, and railcars. In addition, since the wheels on both sides of the axle are configured to be relatively movable together with the bogie frame (side beam), the length of the axle protruding outward from the bogie in a narrow gauge state is small, so that it is easy to fit within the vehicle limit.

(3) In the variable gauge cart according to the third aspect,
The drive device of each axle can be fixed to the corresponding bogie frame, so that a conventional drive device can be used. In addition, since the sliding wheel of one wheel axle is only one side, the other wheel can use the conventional structure.

(4) In the variable gauge cart according to the fourth aspect,
Since the position at which the auxiliary wheel lifts the side beam is closer to the tip of the side beam than the bogie of the third aspect, the side beam can be lifted more smoothly.

(5) In the variable gauge cart according to claim 5,
The lever member is tilted about the pivot point by the auxiliary wheel, and by lifting one end of the link member together with the lock pin,
The restraining relationship between the side beam and the side beam by the lock pin is released.

(6) In the variable gauge cart according to claim 6,
Since the left and right wheels rotate freely, running stability on straight roads is excellent.

(7) In the variable gauge cart according to claim 7,
Both the left and right wheels rotate integrally with the axle, which is no different from the behavior of conventional wheels.

(8) The ground equipment of the gauge changing equipment of the present invention is composed of a rail and a traveling path or a rail and a traveling path and a guide rail, all of which are made of a rigid body and have no movable parts. Therefore, it is rich in durability, easy in security management, suitable as outdoor equipment, and can be used stably for a long period of time.

(9) In the ground equipment of the gauge changing equipment of claim 9, when the vehicle travels from a narrow gauge track to a wide gauge track, the inner guide rail serves to press the wheels.

(10) In the ground equipment of the gauge changing equipment according to the tenth aspect, when the vehicle travels from a wide gauge track to a narrow gauge track, the outer guide rail serves to press the wheels. Further, since the force for pressing the wheels can be relatively large, the section of the relay track can be relatively shortened as compared with the ground equipment having only the rail (claim 8).

(11) In the above-mentioned ground equipment of the gauge changing equipment , the vehicle can run from any direction of the narrow gauge track and the wide gauge track, and can move from the narrow gauge track to the wide gauge track. When traveling, the inner guide rails press the wheels, and when traveling from a wide gauge track to a narrow gauge track, the outer guide rails serve to press the wheels.

(12) The ground changing equipment of the gauge changing equipment according to the twelfth aspect corresponds to the cart according to the third and fifth aspects, wherein the auxiliary wheels are located inside the rails.

(13) The ground equipment of the gauge changing equipment according to claim 13 corresponds to the truck according to claim 4, wherein the auxiliary wheels are located outside the rails.
