Description

本発明は、鉄道車両の連結構造に係り、詳しくは車体の連結部分に取付けられる外幌板の構造に関する。   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.
鉄道車両では、前後の車体間の間隙が一般的には500mmあるため、ゴム材で形成した長さ220mmの外幌板を、連結された車体の相対向する妻面の側部外縁部にそれぞれ取り付けて間隙を縮めるようにしている。   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.
また、車体間の間隙をなくすための両外幌板に予圧縮を各々10mm与えて両外幌板を接触させ、本線走行時に両外幌板間に間隙が生じないようにしたものがある。   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.
しかし、前者の外幌板では、両外幌間に60mm程度の間隙が残り、車体間が不連続になるために、高速走行時には空力音が発生していた。また、本線走行時には、両外幌板はR700mの曲線以下では接触し、構内線でR200mの曲線を通過する場合では、車体間隔が250mmまで縮まるので、縮んだ側の両外幌板は95mmの圧縮変形を受けながら擦れ合う。   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.
一方、後者の外幌板では、両外幌板が常に擦れ合って動くため、外幌板の摩耗が早く、頻繁に交換しなければならなかった。しかも、一方の車体が右に、他方の車体が左に動いた場合には、両外幌板間に段差が生じ、高速走行時には出っ張った部分に空気が衝突して空力音が発生していた。   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. .
そこで本発明は、連続する車体間をなだらかに繋いで、走行中に空力音が発生することを防止すると共に、外幌板の車体断面方向の剛性を確保して走行中に外幌板がばたつくことを抑える一方、車体間の相対変位による変形や、各種の歪みによる大変形にも対応できる鉄道車両の連結構造を安価に提供することを目的としている。   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.
上記の目的を達成するため本発明は、連結車両の相対向する車体の妻面の外縁に取付けられた外幌板にて車両連結部を覆う鉄道車両の連結構造において、前記外幌板は、相対向する車体間を連続してなだらかに繋ぐ表面材と、表面材に覆われて複数の骨によって構成される開放された網目状の骨部材とを、軟質加硫ゴムで一体成形されており、前記骨部材の網目構造の空間部は、相対向する車体間の相対変位による変形に追従できることを特徴としている。 In order to achieve the above object, the present invention provides a railway vehicle connection structure in which a vehicle connection part is covered with an outer hood plate attached to an outer edge of a mating face of a vehicle body opposite to the connected vehicle. and a surface material gently connect continuously between the vehicle body facing each, covered with the surface material and a mesh-like skeleton member which is opened constituted by a plurality of bones, and is integrally molded in a soft vulcanizates The space portion of the mesh structure of the bone member can follow deformation caused by relative displacement between the opposite vehicle bodies.
本発明によれば、外幌板を空間部を有した骨部材と、該骨部材の外側面を覆う表面材とで形成すると共に、前記骨部材と前記表面材とを軟質加硫ゴムで一体成形したので、外幌板の車体断面方向の剛性が確保され、走行中にばたつくことがなく、また、外幌板が車体間の相対偏位による変形に容易に追随でき、各種の歪みによる大変形にも対応できるようになる。さらに、外幌板が連続する車体間をなだらかに繋ぐので、車体の連結部分の空気抵抗を有効に減少させることができると共に、外幌板を安価に提供することができる。   According to the present invention, the outer hood plate is formed of the bone member having the space portion and the surface material covering the outer surface of the bone member, and the bone member and the surface material are integrated with the soft vulcanized rubber. Since it is molded, the rigidity of the outer hood plate in the vehicle cross-section direction is secured, it does not flutter during running, and the outer hood plate can easily follow deformation due to relative displacement between the vehicle bodies, and it can be greatly affected by various distortions. It will be possible to cope with deformation. Furthermore, since the outer hood plates smoothly connect the continuous vehicle bodies, the air resistance of the connecting portions of the vehicle bodies can be effectively reduced, and the outer hood plates can be provided at low cost.
以下、本発明を、図面に示す実施形態例に基づいて詳しく説明する。図1乃至図7は本発明の第1実施形態例を示すもので、連結車両における前後に連結される車体1,2の対向する妻面1a,2aの外縁には、図4に示されるように、車体1,2に連続する外幌板3が取付けられている。 Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. 1 to 7 show a first embodiment of the present invention, Wife surface 1a facing each of the vehicle body 1 which is connected to the front and rear of the articulated vehicle, the outer edge of 2a, as shown in FIG. 4 Thus, the outer hood plate 3 continuing to the vehicle bodies 1 and 2 is attached.
外幌板3は、防振ゴムとして採用されている硬度40度から70度の軟質加硫ゴムで形成され、屋根部4と、肩部5,5と、肩部5,5に連続する側部6,6とから構成されている。   The outer hood plate 3 is formed of a soft vulcanized rubber having a hardness of 40 degrees to 70 degrees, which is employed as an anti-vibration rubber, and is continuous to the roof section 4, the shoulder sections 5, 5, and the shoulder sections 5, 5. It consists of parts 6 and 6.
屋根部4は、図3に示されるように、骨部材に表面材4bが加硫一体成形されるもので、骨部材4aは、図5に示されるように、車体の左右(枕木)方向に平行に延びる複数の横骨4cを、レール方向に延びる波状の複数の縦骨4dで繋いで形成され、横骨4aと縦骨4bとの間には空間部4eを有している。   As shown in FIG. 3, the roof portion 4 is formed by integrally vulcanizing a surface material 4b on a bone member, and the bone member 4a is formed in the left and right (sleeper) direction of the vehicle body as shown in FIG. A plurality of horizontal bones 4c extending in parallel are connected by a plurality of wavy vertical bones 4d extending in the rail direction, and a space 4e is provided between the horizontal bone 4a and the vertical bone 4b.
肩部5及び側部6も屋根部4と同様に、骨部材5a,6aに表面材5b,6bが加硫一体形成されるもので、肩部5の骨部材5aは、図6に示されるように、車体1,2の肩部と同様のカーブを有した車体の左右方向に平行に延びる4本の横骨5cを、前記屋根部4の縦骨4dと同一形状の屋根部側の縦骨5dと、後述する側部6の骨部材6aと同一形状の側部側の縦骨5eとで繋いで形成され、隣り合う横骨5c,5cの間には空間部5fを有している。さらに、側部6の骨部材6aは、図1及び図7に示されるように空間部6cを備えた網状に形成されている。また、肩部5の縦骨5d,5eが、屋根部4の縦骨4dと側部6の骨部材6aと同一形状に形成されることから、縦骨5d,5eと、屋根部4の縦骨4d及び側部6の骨部材6aとをなだらかに繋げることができる。   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. . Further, 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.
この屋根部4,肩部5,5及び側部6,6の、車体前後方向の両妻側端面には、図2の側部6の一例に示す如く、可撓性材または鋼材,アルミ材,ステンレス材等の剛性の高い材料からなる取付け板7が加硫により一体成形されていて、外幌板3は、各取付け板7を車体1,2の妻面1a,2aの外縁部にボルト止めすることによって取付けられる。   As shown in an example of the side portion 6 in FIG. 2, the roof portion 4, the shoulder portions 5 and 5, and the side portions 6 and 6, on both ends in the longitudinal direction of the vehicle body, as shown in the example of the side portion 6 in FIG. 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. Installed by locking.
上述の実施形態例では、表面材4b,5b,6bが骨部材4a,5a,6aの外側面を覆うことにより、外幌板3が車両1,2の妻面1a,2a間をなだらかに繋ぐことができ、車両走行時に空気抵抗を減少させることができる。また、各骨部材4a,5a,6aによって、外幌板3の車体断面方向の剛性が確保され、外幌板がばたついて音が発生するおそれがない。   In the above-described embodiment, the outer covering plate 3 gently connects the end faces 1a, 2a of the vehicles 1, 2 by covering the outer surfaces of the bone members 4a, 5a, 6a with the surface materials 4b, 5b, 6b. The air resistance can be reduced when the vehicle is running. Further, the rigidity of the outer hood plate 3 in the vehicle body cross-sectional direction is ensured by the bone members 4a, 5a, 6a, and there is no possibility that the outer hood plate flutters and sounds are generated.
さらに、外幌板3全体が可撓性のある軟質加硫ゴムで形成されると共に、骨部材4a,5a,6aに、骨部材4b,5b,6bの変形を許容する開放された空間部4e,5f,6cが形成されていることにより、外幌板3が、車体1,2間の相対変位による変形に容易に追随できることは勿論、各種の歪みによる大変形にも対応できるようになる。また、骨部材4a,5a,6aと表面材4b,5b,6bとは、軟質加硫ゴムで加硫一体成形されているので、幌外板3を安価に形成することができる。 Further, the outer hood plate 3 as a whole is formed of flexible soft vulcanized rubber, and the open space 4e that allows the bone members 4a, 5a, 6a to deform the bone members 4b, 5b, 6b. , 5f, and 6c, the outer hood plate 3 can easily follow deformation due to relative displacement between the vehicle bodies 1 and 2, and can cope with large deformation due to various distortions. Further, since the bone members 4a, 5a, 6a and the surface materials 4b, 5b, 6b are integrally vulcanized with soft vulcanized rubber, the hood outer plate 3 can be formed at low cost.
図8は、取付け板の他の実施形態例を示すもので、取付け板8は、前記実施形態例と同様、鋼材,アルミ材,ステンレス材等の比較的剛性の高い材料で形成され、屋根部4,肩部5,5及び側部6,6の車体前後方向の両端面の軟質加硫ゴム材に加硫接着して取付けられる。取付け板8にはボルト挿通孔8aが適宜穿設されていて、屋根部4,肩部5,5及び側部6,6は、各取付け板8を車体1,2の妻面1a,2aの外縁部にボルト止めすることによって取付けられる。   FIG. 8 shows another embodiment of the mounting plate, and the mounting plate 8 is formed of a material having a relatively high rigidity such as a steel material, an aluminum material, a stainless steel material, and the like as in the above embodiment. 4, the shoulder portions 5 and 5 and the side portions 6 and 6 are attached by vulcanization adhesion to the soft vulcanized rubber material on both end surfaces in the longitudinal direction of the vehicle body. Bolt insertion holes 8 a are appropriately drilled in the mounting plate 8, and the roof portion 4, the shoulder portions 5, 5 and the side portions 6, 6 are connected to the mounting surfaces 8 of the vehicle bodies 1, 2 a. Installed by bolting to the outer edge.
図9及び図10は、本発明の第2実施形態例を示すもので、外幌板10の骨部材10aの車体前後方向の両端部には、車体中央側に突出する車体取付け用の脚部10bが設けられ、脚部10bの先端に取付け板11が加硫により一体成形されている。取付け板11は、ボルト12によって前記妻面1a,2aの外縁部より車体中央側に取付けられる。   FIGS. 9 and 10 show a second embodiment of the present invention. At both ends in the longitudinal direction of the vehicle body of the bone member 10a of the outer hood plate 10, leg portions for mounting the vehicle body projecting toward the center of the vehicle body are shown. 10b is provided, and a mounting plate 11 is integrally formed by vulcanization at the tip of the leg 10b. The attachment plate 11 is attached to the vehicle body center side from the outer edge part of the said end faces 1a and 2a with the volt | bolt 12. FIG.
図10は、車両の曲線通過時に、外幌板10に前後方向の引っ張りや圧縮歪みが生じたり、S字曲線通過時に左右方向の剪断歪みがそれぞれ発生して、外幌板10が大変形しようとする時に、脚部10bと車体1,2の妻面1a,2aが離間すると共に空間部10cが変形することによって、外幌板10の大変形を許容する状態を示している。   FIG. 10 shows that the outer hood plate 10 is greatly deformed by a longitudinal tensile or compressive strain generated on the outer hood plate 10 when passing through the vehicle curve, or a lateral shear strain generated when passing the S-shaped curve. In this case, the leg portion 10b and the end faces 1a and 2a of the vehicle bodies 1 and 2 are separated from each other and the space portion 10c is deformed to allow large deformation of the outer hood plate 10.
このように、第2実施形態例では、外幌板10が受ける大変形を脚部10b及び空間部10cで吸収させることができ、車体1,2間の相対変位による変形に外幌板3がより容易に追随できるようになる。   As described above, in the second embodiment, the large deformation received by the outer hood plate 10 can be absorbed by the leg portion 10b and the space portion 10c. It becomes easier to follow.
図11及び図12は、本発明の第3実施形態例を示すもので、本実施形態例の外幌板12は、骨部材12aに表面材12bを一体加硫成形する際に、骨部材12aの空間部12cを覆う表面材12bを車体外方へ突出させ、表面材12bに突部12dと凹部12eとが形成されている。   FIGS. 11 and 12 show a third embodiment of the present invention. The outer hood plate 12 of this embodiment is formed by the bone member 12a when the surface material 12b is integrally vulcanized and formed on the bone member 12a. A surface material 12b covering the space 12c is projected outward from the vehicle body, and a protrusion 12d and a recess 12e are formed on the surface material 12b.
上述のように形成することにより、外幌板12が大変形を受けたり、車体1,2間の相対変位が生じた場合に、凹部12eが外幌板12の変形を許容し、外幌板12が車体1,2の動きに容易に追随できるようにしている。   By forming the outer hood plate 12 as described above, the recess 12e allows the outer hood plate 12 to be deformed when the outer hood plate 12 undergoes large deformation or relative displacement between the vehicle bodies 1 and 2 occurs. 12 can easily follow the movement of the vehicle bodies 1 and 2.
尚、外幌板は、上述の各実施形態例のように車体1,2の妻面1a,2aの外縁部に連続して取付けるものに限らず、各実施形態例の外幌板を車体の屋根部と両側部とに分割して設けてもよく、さらにそれ以上に細かく分割して取付けるものでもよい。また、図13及び図14に示されるように、骨部材6a間の表面材6bのばたつきを抑えるために、補強リブ6dを適宜設けてもよい。   The outer hood plate is not limited to the one that is continuously attached to the outer edge portions of the end faces 1a and 2a of the vehicle bodies 1 and 2 as in each of the above-described embodiments, and the outer hood plate of each embodiment is not limited to that of the vehicle body. You may divide and provide in a roof part and both sides, and may also divide | segment and divide | segment more finely than that. Further, as shown in FIGS. 13 and 14, reinforcing ribs 6d may be provided as appropriate in order to suppress fluttering of the surface material 6b between the bone members 6a.
