BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting an outer hood for a railway vehicle and a mounting structure, and more specifically, to a vehicle connecting portion suitable for a railway vehicle having a side shape curved or bent in the vertical direction. The present invention relates to a method of attaching an outer hood that is attached to both side surfaces, and a structure for attaching an outer hood attached by the method.

[0002]

2. Description of the Related Art As shown in FIGS. 6 (a) and 6 (b), a connecting portion 2 of a vehicle 1 has an appearance of the vehicle 1 and reduces air resistance when the vehicle is running. An outer hood 3 made of a rubber plate having a U-shaped cross section is attached for the purpose of, for example, preventing the vehicle from falling to the track in the space between the vehicles.

Conventionally, the outer hood 3 as described above is shown in FIG.
As shown in (b), the flexible plate-like body 4 made of rubber or the like having a substantially rectangular shape in which the vicinity of the central portion in the width direction is formed thin is folded in two at the thin portion, and the connecting portion 2 of the vehicle 1 is formed. It was attached by a plurality of fixing metal fittings 6 along the form 5 installed so as to face both side surfaces (hereinafter referred to as gable surfaces).

A plurality of folds 7 are formed on one side surface of the outer hood 3 which is located inside the vehicle 1 when the outer hood 3 is folded in two, and the folds 7 bend or bend the outer plate of the vehicle side when the outer hood 3 is folded in two. It has played a role of absorbing the circumferential length difference between the outer side surface and the inner side surface due to.

However, when the degree of curving or bending of the side shape of the vehicle 1 becomes remarkable, the fixing portion of the outer hood 3 to the formwork 5 fits in, but the two-folded portion 8 tries to maintain the straight state, so that FIG. As shown in FIGS. 9A and 9B, the double-folded portion 8 buckles, and as shown in FIGS. 9A to 9C, the longitudinal end portion 8 ′ of the outer hood 3 extends from the mounting end portion 9 to the vehicle 1. There is a problem in that it swells to the outside of the vehicle and protrudes to the outside of the vehicle 1.

Such a buckling phenomenon of the double-folded portion 8 and the protrusion from the side surface of the vehicle are not only dangerous when the vehicle is traveling, but also the appearance of the connecting portion 2 is deteriorated and the wind pressure during high-speed traveling. As a result, the outer hood 3 becomes fluttering, which causes a decrease in the durability of the outer hood 3.

In particular, in recent years, as the speed of railway cars has increased, the shape of the outer plate on the side surface of the train has become more and more curved or bent in the vertical direction. It's getting harder.

In order to solve this problem, Japanese Patent Laid-Open No. 11-1
As disclosed in Japanese Patent No. 71011, an outer hood having a fan-shaped planar shape has been proposed, and by this, problems such as buckling of the two-folded portion of the outer hood and protrusion from the vehicle side surface have been solved.

[0009]

However, in order to manufacture an outer hood having a fan-shaped planar shape, the mold used for molding becomes expensive, and moreover, it is often used in accordance with the shape of the outer plate on the side surface of the vehicle. The need for a molding die of the above remained a new problem.

The object of the present invention is to prevent the buckling phenomenon of the folded portion and the protrusion from the side surface of the vehicle while using the conventional outer hood made of a substantially rectangular plate-like body and to prevent the appearance and outside of the vehicle connecting portion. An object of the present invention is to provide a method for mounting an outer hood for a railway vehicle that improves durability of the hood, and a structure for mounting an outer hood mounted by the method.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

In each figure, the same constituents are designated by the same reference numerals, and the duplicated description will be omitted.

FIG. 1 is a partial perspective view for explaining a situation in which the outer hood of the present invention is mounted on a mold, and the outer hood 3 is mounted on the mold 5.

Here, since the mold frame 5 is attached to the end face along the outer plate shape forming the side surface of the vehicle in the longitudinal direction, when the outer plate shape of the vehicle is a curved surface in the vertical direction or at the bent portion. In the case where the outer hood 3 is provided, both ends in the width direction of the outer hood 3 are attached so as to form a curved shape or a bent shape according to the curvature of the outer plate shape of the vehicle.

A fold 7 is formed on a surface of the outer hood 3 located inside the vehicle, and an outer surface and an inner surface of the outer hood 3 when the fold 7 is attached according to a vertical curvature of an outer plate of the vehicle. It absorbs the difference in circumference.

Here, when the vertical curvature of the outer panel of the vehicle is extremely large, the half-folded portion 8 tries to maintain the straight state, and therefore the longitudinal end portion 8'of the half-folded portion 8 is shown in the drawing. It protrudes toward the outer side of the vehicle indicated by the arrow A, and is shown in FIG.
The state becomes as shown in.

In order to prevent this, the outer hood 3 at a position corresponding to the central portion of the vehicle outer plate which is curved or bent in the vertical direction.
The inner mounting end portion 9 is pulled in and attached to the bottom surface side of the form 5 as shown by an arrow B in FIG.

In this way, a part of the attachment end 9 of the outer hood 3 to the mold 5 is pulled toward the bottom side of the mold 5 in accordance with the vertical curvature of the outer plate of the vehicle, so that the half-folded part 8 is folded. The longitudinal end 8'is pulled in the direction opposite to the arrow A in the figure (inside the vehicle), and the protrusion to the outside of the vehicle is eliminated.

Here, the amount of drawing of the mold 5 to the bottom side is adjusted each time according to the degree of vertical bending or bending of the outer plate of the vehicle.

That is, in a portion of the outer plate of the vehicle where the vertical curvature is large, the amount by which the mounting end 9 is pulled toward the bottom surface of the form 5 at a position corresponding to the curved or bent central portion is increased, and its surroundings. Is gradually reduced.

The appropriate amount of retraction is usually 5 to 20 mm. If it is less than 5 mm, it is not sufficient to eliminate the protrusion of the two-folded portion 8 to the outside of the vehicle, and if it exceeds 20 mm, the two-folded portion 8 tends to buckle. At the same time, the width of the outer hood 3 locally changes when the connecting portion is viewed from the side of the vehicle, impairing the appearance.

FIG. 2 (a) is a partial perspective view for explaining the positions of the mounting holes provided in the outer hood for mounting the outer hood of the present invention on the form, for mounting the form 5 inside the vehicle. The case where the position of the mounting hole 10 provided in the outer hood 3 is changed in the width direction of the outer hood 3 is shown.

Here, the rate of changing the mounting hole 10 in the width direction of the outer hood 3 is adjusted according to the vertical curvature of the outer plate of the vehicle.

As described above, the mounting hole 10 is provided at a position which is changed in the width direction from the mounting end portion 9 of the outer hood 3, and is fixed to the mounting hole of the form 5 arranged equidistantly from the bottom surface. As a result, the attachment end 9 of the outer hood 3 is pulled in and attached to the bottom surface side of the form 5 in accordance with the vertical curvature of the outer plate of the vehicle, so that the two-folded portion 8 protrudes outside the vehicle. Can be prevented.

FIG. 3 is a partial perspective view for explaining the positions of the mounting holes provided in the frame for mounting the outer hood of the present invention. The positions of the mounting holes 11 on the vehicle inside of the frame 5 are shown in FIG. 5 shows a case where the bottom surface of No. 5 is changed.

Here, the rate of changing the mounting hole 11 with respect to the bottom surface of the mold 5 is adjusted according to the vertical curvature of the outer plate of the vehicle, as in the case of FIG.

As described above, the mounting holes 11 are provided at positions changed with respect to the bottom surface of the form 5, and the mounting end portions 9 are attached to the mounting holes 11.
By fixing the outer hood 3 having the mounting holes 10 arranged equidistantly in the width direction from the bottom, the mounting end 9 of the outer hood 3 is consequently fixed according to the vertical curvature of the outer plate of the vehicle. Since it has been installed by pulling it to the bottom side of
It is possible to prevent the half-folded portion 8 from protruding outside the vehicle.

FIG. 4 is a partial perspective view similar to FIG. 3 for explaining another embodiment of the mold for attaching the outer hood of the present invention, in which the mold 5 is attached to the outer hood 3. In order to facilitate the pulling in of the mold 9, the inside surface of the vehicle of the formwork 5 is processed into a taper surface facing inward, and a mounting hole 11 is formed in the taper surface as in FIG. Shows.

The structure, operation and effect of each part in this embodiment are the same as those in FIG.

[0037]

EXAMPLE As shown in FIGS. 5 (a) and 5 (b), an outer hood 3 (liter = 1100 mm, w) formed of a substantially rectangular rubber plate-like body having a thin portion formed near the center in the width direction. =
394 mm, t = 8 mm) was manufactured.

On one mounting portion 9 side of the outer hood 3, five mounting holes 10 (inner diameter 10 mm) are formed in the longitudinal direction at a position of 20 mm widthwise inward from the mounting portion 9, and the other mounting portion 9 side. 40mm, 47.5mm, 45mm and 42.5m inward in the width direction from the mounting portion 9, respectively.
5 mounting holes 10 in the longitudinal direction at positions of m and 40 mm
a, 10b, 10c, 10d, 10a (inner diameter 10 mm)
Was formed.

When this was mounted on the formwork 5 installed on the end face of the vehicle, no protrusion of the half-folded portion 8 to the outside of the formwork 5 was observed.

In the above description of the embodiment, the mounting end 9 on the inner side of the outer hood 3 at the position corresponding to the vertical bending or bending center of the outer plate of the vehicle is pulled into the bottom surface of the form 5. Although the case where the outer hood 3 is mounted on the form 5 is described above, the mounting end portion of the outer hood 3 located outside the vehicle to the form 5 depends on the vertical curvature of the outer plate of the vehicle side surface. It is also possible to lift and attach from the bottom side of the form 5, and in this case, as shown in FIG.
As shown in, the position of the mounting hole 10x provided in the outer hood 3 for mounting the mold 5 inside the vehicle is changed so that the bottom surface side is easily pulled up in the width direction of the outer hood 3.

Here, the rate of changing the mounting hole 10 in the width direction of the outer hood 3 is adjusted according to the vertical curvature of the outer plate of the vehicle.

[0042]

As described above, according to the present invention, when the outer hood is mounted on the form while using the conventional outer hood made of the substantially rectangular plate-like body, the mounting end portion inside the vehicle is mounted outside the vehicle. Depending on the shape of the plate, it is possible to prevent the buckling phenomenon of the folded part and the protrusion from the side of the vehicle by pulling it toward the bottom of the frame.

Therefore, without changing the outer hood itself, it is possible to cope with a wide variety of vehicle outer plate curve or bending by adjusting the amount of drawing into the bottom surface of the formwork. It is possible to improve the appearance of the connecting part and the durability of the outer hood.
