Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a railway vehicle connection structure, and more particularly to a structure of an outer hood plate attached to a connection part of a vehicle body.
[0002]
[Prior art]
In railway vehicles, the gap between the front and rear vehicle bodies is generally 500 mm, and therefore, a 220 mm long outer hood plate is formed on each side edge of the opposite face of the connected vehicle body. It is attached to reduce the gap.
[0003]
In addition, there is a type in which pre-compression is applied to both the outer hood plates for eliminating the gap between the vehicle bodies to 10 mm to bring the outer hood plates into contact with each other so that no gap is generated between the outer hood plates when traveling on the main line.
[0004]
[Problems to be solved by the invention]
However, in the former outer hood plate, a gap of about 60 mm remains between the two outer hoods, and the vehicle body becomes discontinuous. Also, when running on the main line, both outer hood plates contact below the curve of R700m, and when passing through the curve of R200m on the premises line, the distance between the vehicle bodies is reduced to 250mm. Rubbing while undergoing compression deformation.
[0005]
On the other hand, in the latter outer hood plate, both outer hood plates always rub against each other and move. Therefore, the outer hood plates were worn quickly and had to be replaced frequently. Moreover, when one vehicle body moved to the right and the other vehicle body moved to the left, a step was formed between both outer hood plates, and air collided with the protruding portion during high-speed traveling, generating aerodynamic noise. .
[0006]
In view of this, the present invention gently connects between successive vehicle bodies to prevent aerodynamic noise from being generated during traveling, and ensures the rigidity of the outer hood plate in the cross-sectional direction of the vehicle body so that the outer hood plate flutters during traveling. On the other hand, an object of the present invention is to provide a railway vehicle connection structure that can cope with deformation caused by relative displacement between vehicle bodies and large deformation caused by various distortions at low cost.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a railway vehicle connection structure in which a vehicle connection portion is covered with an outer hood plate attached to an outer edge of a mating face of a vehicle body facing each other of the connected vehicle. The roof part, comprising a roof part, side parts, a shoulder part continuous to both of these parts, and a mounting plate to the outer edge of the opposite body side face of the both sides in the longitudinal direction of the body of each part. Each of the side portion and the shoulder portion is formed by integrally forming a bone member constituted by a plurality of bones and a surface material covering the outer surface of the bone member with a soft vulcanized rubber, and constitutes each bone member. Between the plurality of bones, spaces for allowing deformation of the bone members are formed, and the bone members of the roof portion include a plurality of transverse bones extending in parallel to the sleeper direction and a plurality of longitudinal bones extending in the rail direction. And the space is formed between the transverse bone and the longitudinal bone, The bone member of the portion is formed in a net shape, and the space portion is formed between the nets, and the bone member of the shoulder portion includes a plurality of horizontal bones extending in parallel to the sleeper direction and a roof extending in the rail direction. It is characterized in that it is formed by connecting a longitudinal bone on the side portion and a longitudinal bone on the side portion side, and the space portion is formed between the adjacent lateral bones .

[0011]
Similarly to the roof portion 4, the shoulder portion 5 and the side portion 6 are formed by integrally vulcanizing the surface members 5b and 6b on the bone members 5a and 6a. The bone member 5a of the shoulder portion 5 is shown in FIG. As described above, the four horizontal bones 5c extending in parallel in the left-right direction of the vehicle body having the same curve as the shoulder portions of the vehicle bodies 1 and 2 are formed on the roof portion side in the same shape as the vertical bone 4d of the roof portion 4. A bone 5d is connected to a bone member 6a of a side portion 6 to be described later and is connected to a longitudinal bone 5e on the side of the same shape, and a space portion 5f is provided between adjacent lateral bones 5c and 5c. . Furthermore, the bone member 6a of the side portion 6 is formed in a net shape having a space portion 6c as shown in FIGS. Further, since the vertical bones 5d and 5e of the shoulder portion 5 are formed in the same shape as the vertical bone 4d of the roof portion 4 and the bone member 6a of the side portion 6, the vertical bones 5d and 5e and the vertical bones of the roof portion 4 are formed. The bone 4d and the bone member 6a of the side portion 6 can be smoothly connected.
[0012]
As shown in the example of the side portion 6 in FIG. 2, the roof portion 4, the shoulder portions 5, 5 and the side portions 6, 6 have both ends in the longitudinal direction of the vehicle body. A mounting plate 7 made of a highly rigid material such as stainless steel is integrally formed by vulcanization, and the outer hood plate 3 has each mounting plate 7 bolted to the outer edges of the end faces 1a and 2a of the vehicle bodies 1 and 2.
