Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side plate structure for a railway vehicle in which a single body is supported by a bogie ζ.

As is well known, recently stainless steel materials have been widely used for car bodies (111 bodies) in order to reduce the weight of railway vehicles. Vehicles made of stainless steel have the practical advantage of being able to be used unpainted without having to worry about corrosion, and that the material's mechanical strength allows the plate thickness to be kept to a minimum.

However, the loads that apply to the entire vehicle include vertical load, torsional load, car end load, and internal pressure, and the vertical charge applied to the structure is mainly handled by the * structure. For this reason, conventionally,
When manufacturing parts, the side plates (
1) is shown as a single point @ edge in Figure 1 (it has an arcuate shape. However, when manufacturing the side m, the straight 114+1 provisional (1) is assembled into an arcuate shape (18 crooked bending), so the first
The top edge of the side plate (1) is cloudy as shown by the solid line in the figure.
4) is on the elongated side, so it can be easily adapted to a relatively soft T, but since its lower end (5) is rounded, it cannot fully absorb distortion, resulting in a wavy shape. As a result, distortions and wrinkles occur particularly on the lower side of the side plates (11), resulting in a very unsightly appearance.

In the case of a side plate made of iron plate, the above-mentioned distortions and wrinkles can be eliminated by so-called heat strain relief treatment, but in the case of a side plate made of stainless steel plate, heat strain relief treatment can be performed. Can not. Therefore, although railway cars using side plates made of stainless steel plates have a relatively long service life, the fact that they are not painted means that they have a very poor appearance.

The present invention was invented in view of the above-mentioned actual situation.If the side plate is composed of a plurality of strip-shaped plates, it is possible to prevent distortion by devising the shape of these strip-shaped plates. This paper attempts to propose a 111& structure for a railway vehicle that does not cause wrinkles.

Below, with reference to Figures 2 to 7 for the non-inventive embodiments,
The vehicle body 01 includes an underframe aυ, a roof portion 04, and side columns (c). In Figure 2, a is the curtain part, b
C is the window and vent area, and C is the waist area.

Figures 6 to 5 show the side plate (waist outer plate) attached to the waist C.
This shows a first embodiment of the invention. The 1111Yu α-tan of this embodiment includes, for example, four belt-shaped plates (161
(171(IIQ) (2) consists of a waist outer panel consisting of II and a window outer panel (2), and these strip-shaped panels (161-(l and window outer panel 122+ are in the same vertical position) The strip plates Q61-09 are formed, for example, from roll-formed (drawn) flat strip plates into a cross-sectional shape as shown in FIG. -t19 is an assembly special number which is curved at the same time in the direction away from the trolley (l: side) between the supported part h (!: B"': 6 in Fig. 6, and the inside of the supported part The end portion is constructed so that it is curved in the direction (upward) away from the cart, and is bonded by spot welding.As shown in Fig. 1 piece of the lower edge of the strip plate 061-H other than the
In addition, the cross section extending in the horizontal direction is formed with a V-shaped protrusion (7), and a strip plate 0bl disposed at the top.
The upper wire number of the strip plate un -Ql other than the above is provided with a bent portion 3υ in order to increase the buckling strength at the portion indicated by d. In addition, as shown in FIG. 5, a portion of the above-mentioned bent portion Qυ corresponding to the side pillar (c) constituting the structure is formed with a notch CI!41. 6 In Figure 1, (27a) is a window opening/closing opening, and (27b) is a door opening/closing opening.

However, as clearly shown in Fig. 4, the strips α[9Q7), (17)01, and Qll
With the lower edge and upper edge of 09 superimposed on each other, keep the curved shape M4 as described above and spot on the side column (c), lower window stringer 0-, side beam 04, etc. Welding (2Bm
) ~(288), (29a) ~(29C), (30ri ~(3[IC), (31aX31b) and (32a)
(32b) @The trowels are respectively joined. And as shown by the dashed line in Fig. 6, the window outer panel is formed in the same shape as the strip plates ae~0.
The supported part A of the vehicle body Ql is joined by this.
A 9Ql groove Q5 is formed in which the portion between B and B is upwardly curved, and the corresponding end portions are upwardly curved.

In the manufacturing process of a 09 like C, when the straight side plates (band plates 00 to 0) are curved into an arch shape, the first
As shown in the figure, it consists of a single board and has a height of 1.
When the side plate (1) is bent, a large amount of slack is formed at the lower end (5), and this slack appears as unevenness on the plane. If the side beams C and C are joined together by spot welding, the unevenness will remain as distortion. It should be noted that since the wainscot is spot-bonded with unevenness, this distortion cannot be eliminated even if the load is applied and the vehicle body becomes horizontal, thus degrading the appearance of the vehicle.

However, in this embodiment, as shown in FIG. 4, the wainscot board is divided into several low-height boards. Since the distance between the two is narrow, bending deformation of the band-like temporary position ~al is allowed within the range of elastic deformation of the lower end, and there is little slack at the lower end, so unevenness on the plane is also very small. You can. Since the parts are spot-bonded together with the frame in this state, the completed side 11QS has fewer irregularities (distortions).

In addition, the bent portions Qυ of the belt-shaped plates Q71 to α9 are arranged on the inside to prevent water from entering the inside of the vehicle body Ql, and a fifth As shown in the figure, the side posts (c) are fitted and arranged, and the strip plates a9 to a are arranged and fixed in close contact with the side posts (c).

When the car body 11 assembled in this way is supported by a bogie f (not shown), a stress F corresponding to the weight of the supported parts A and B of the car body 01 + the car body QG here is applied. This stress is transmitted through the side column (231 @ 4i11
tts f works. At this time, the strip plate Q61-Q
If 'J were a single plate, the protrusion (4) would deform into an acute angle and no shear force would be transmitted; however, as in this example, the protrusion (4)
Since spot welding is performed on both the upper and lower parts of 2), the shearing force is transmitted to the strip plates aυ~4 without interruption.

According to the octopus side structure a4, when the strip plates Oe to α are joined together, a closed section with a roughly triangular cross section is formed at the protrusion (7), so it has high strength. In addition to being a cylinder and structure, the bending part CI! By providing II, the buckling strength of the portion indicated by d in FIG. 4 is increased. For this reason, the strip plate 1161-Q! Even if the thickness of the plate 1 is made thinner, sufficient strength can be obtained for the sides and structure (151), and it is possible to significantly reduce the weight of the tabletop area.

Moreover, since the joining of the strip plates (161 to 11) is performed near the protrusion, and this joining is done by spot welding, the material of the welded part is different from that of arc welding, etc. It does not cause any cracks and therefore does not spoil the appearance of the side structure haze, giving it a good appearance.It is also advantageous in that the respective strip plates 08 to Ql are the same.

Figure 7 and 1f! FIG. 8 shows a second embodiment of the present invention.

In this embodiment, as shown in FIG. Strip plate 1341 (to)
and a strip plate (2) having a projection ■ on the upper edge.
It consists of 9 or more. These strip plates (161-Q
The former is made of a stainless steel plate as in the previously described first embodiment, and is formed into the same external shape as the strip plate +Ie-Ql. The upper and lower edges of the band-like plates are overlapped and joined by spot welding as shown in Figure 7. The ends of the strips adjacent to each other (B), (2) (To) and Seki (To)
In the overlapping part of the strip plates arranged on the inside, the protrusions 4 of the strip plates arranged on the inside protrude inwardly, and the protrusions m of the strip plates arranged on the outer side protrude inwardly.
(It is configured so that 2Q protrudes outward.

The ends of the uppermost strips are joined to the lower window stringer (2119), and the lowermost strips are joined to the side beams of the underframe αυ using spot welding trowels. Each strip plate No. 08 to a1 has % side pillars (134
In the corresponding portions, notches that cross the protrusion CXJ are formed.

Even in the case of 5eas configured in this way, the same effects as in the case of the above-mentioned embodiments can be achieved.

Although the present invention has been described above with reference to Examples, the present invention is not limited to these Examples, and various changes and modifications can be made based on the technical idea of the present invention.

For example, Confucian Q! The number of strip plates constituting the vehicle body 9 is not limited to four, and can be increased or decreased as needed. It goes without saying that the present invention can be applied.

As described above, the present invention provides a method in which at least two car end portions corresponding to the supported portions of the vehicle body are bent in a direction away from the bogie, and the corresponding portions between the supporting portions are bent in a direction away from the bogie. The 9Allll of the vehicle body is constructed by combining a plurality of thinly curved strip plates with their positions shifted in the vertical direction by I.

Therefore, the side plate structure of the railway vehicle of the present invention is made up of a plurality of strip plates, and the shape of each strip plate is shaped as described above. At the same time as it is possible to reduce distortion during the process, the rigidity of the completed car body is also high, so it is possible to reduce the occurrence of deformation (distortion) caused by disturbances such as electricity and vibration, so it is possible to reduce distortions and wrinkles that are unfavorable to the appearance. This can be effectively prevented from occurring. Furthermore, since each strip plate can be manufactured using a compact molding machine, it is advantageous in terms of manufacturing costs.
