Abstract

PROBLEM TO BE SOLVED: To reduce whistling sounds produced by a single arm type pantograph by reducing the air resistance of an intermediate hinge section by installing a guide bar to the anti-bending side of the hinge section. SOLUTION: Since a guide bar 12 is installed to the anti-bending side of an intermediate hinge section, the air flow which comes into collision with the guide bar 12 arranged at an appropriate distance from the hinge section on the wind side is divided into upper and lower parts by the bar 12, and a turbulent flow area which is several times as large as the bar 12 is formed on the rear side of the bar 12, when the hinge section runs in the anti-bending direction. Then, the hinge section is enclosed in the turbulent flow area and, in view of the structure of the turbulent flow layer, it seems to be only the guide bar 12 existing in the air current without the presence of the hinge section. Therefore, the air resistance of the hinge section is reduced to a value which is nearly equal to that of the guide bar 12 being several times in resistance as small as the intermediate hinge and the same state as that when a hinge cover 10 is attached to the bending side of the intermediate hinge, while the hinge runs in the bending direction, resulting in lower whistling sounds.

The conventional single-arm pantograph is constructed as described above, and the intermediate hinge portion of the framework is provided with a bearing, a bush, and a pin for rotatably connecting the upper frame and the lower frame. Since the train has a complicated shape with many components such as shafts, when the train travels at high speed, the air resistance increases and the wind noise increases. In order to reduce this, a flutter side hinge cover is provided on the flutter side of this portion.

However, the flutter side hinge cover is effective in reducing air resistance and wind noise when traveling in the fluttering direction, but is ineffective when traveling in the anti-fluttering direction. At present, there is no shape effective for running in the anti-fluttering direction, and it is necessary to cope with the folded state where the angle between the upper frame and the lower frame is almost 0 °, so the mounting method is difficult ,
There was no effective anti-flutter side hinge cover. Therefore,
In the conventional single arm type pantograph, the air resistance of the intermediate hinge portion tends to be larger when traveling in the anti-fluttering direction than when fluttering, and the wind noise tends to be larger.

According to the present invention, there is provided a single arm type pantograph which eliminates the tendency that the intermediate hinge portion has a large air resistance and a large wind noise when traveling in the anti-fluttering direction as described above. It is as follows. The reason why the flutter side hinge cover is effective when the intermediate hinge part travels in the fluttering direction is that, as is clear from FIG. This is because they flow separately. The effect of reducing the air resistance can be achieved if the airflow hitting the intermediate hinge portion is made to flow smoothly even when traveling in the anti-fluttering direction.

For this reason, in the present invention, without attaching the hinge cover, the intermediate hinge is separated by an appropriate distance on the anti-fluttering side and is moved forward (upwind) in the anti-fluttering direction in a horizontal direction perpendicular to the vehicle traveling direction. For example, a guide bar having a cylindrical shape is provided in the first embodiment. The length of the guide bar is substantially the same as the horizontal width of the intermediate hinge portion. The guide bar is rotatably supported by the other end of a support rod rotatably supported from both sides or one side of the upper frame and the lower frame. The shape of the guide bar is not limited to a cylindrical shape, but may be any shape such as a drum shape or a prism shape.

The operation of each of the above means will be described as follows.

Then, the intermediate hinge portion is included in the turbulent flow area, and when viewed from the flow of air, only the guide cover exists in the air current, and it is as if the intermediate hinge portion does not exist. Therefore, the air resistance is a fraction of that of the intermediate hinge.
The resistance is reduced to the same level as the resistance of only the guide cover having the size of, and the state is the same as that when the flutter-side hinge cover is attached during traveling in the fluttering direction, and the wind noise is reduced. The action of the support bar supporting both ends of the guide cover is such that even if the height of the pantograph changes while the train is running and the angle between the upper frame and the lower frame changes, the position of the guide cover in the height direction is intermediate. It is a child that holds almost the same height as the hinge. Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The pantograph of the present invention is constructed as described above, and its operation will be described below. 3 to 5 are illustrations showing an air flow for explaining the aerodynamic action of the guide bar.

In FIG. 4, since the front area of the intermediate hinge portion with respect to the airflow is large, a large turbulence region is formed at the rear, and the air resistance is large and the wind noise is large. FIG. 5 shows a case of the present invention, in which the airflow is divided into upper and lower portions by hitting a guide bar 12 arranged on the windward side of the intermediate hinge portion, and a turbulent flow region is formed behind the guide bar. Since the size of the turbulent flow area is about three times as large as the guide bar, the intermediate hinge portion is included in the wake of the guide bar, and the air flow passes without being disturbed by the intermediate hinge portion. Therefore, the air resistance of the intermediate hinge portion during anti-fluttering travel is substantially equal to the air resistance of only the guide bar, and is significantly reduced. Therefore,
Wind noise as well as air resistance during anti-fluttering travel is reduced.

In this embodiment, the guide bar is illustrated and described as having a cylindrical shape, but the operation is the same even if the guide bar has a prismatic shape. Guide bar 2 shown in FIG.

When the pantograph is folded, the upper frames 6 and 7 and the lower frame 4
2 shows a guide bar having an intermediate portion made thinner in consideration of a narrower interval between the guide bar and the guide bar. In this case, even if the intermediate portion is narrow, the air flow formed at both ends and the air flow at the intermediate portion interfere with each other, and a turbulent flow region similar to that shown in FIG. 5 is formed behind the guide bar. This is the same as the first embodiment.

Although not shown, it is possible to support the guide bar from the upper frame 6 with a support rod and a torsion spring in the same manner.
