Description

本発明は、前後の車両同士を連結する連結部における車両間の空間を塞ぐ高速鉄道車両の外幌装置に関する。 The present invention relates to an outer hood device for a high-speed railway vehicle that closes a space between vehicles at a connecting portion that connects front and rear vehicles.

高速鉄道車両の走行時には、その車体の側部や屋根部に沿って走行風が流れるので、この走行風により、車体表面に凹凸部があると、激しい渦流が生じて、風切り騒音が増大し、また走行抵抗が増大する。すなわち、高速鉄道車両の場合、車両連結部において車両間に空間があると、風切り騒音と走行抵抗が増大する原因となるため、大きな問題となる。そこで、高速鉄道車両においては、前後の車両同士を連結する連結部における車両間の空間を外幌装置で塞ぐことが一般に行われている。 When traveling on a high-speed railway vehicle, traveling wind flows along the sides and roof of the vehicle body, so if there are irregularities on the surface of the vehicle body due to this traveling wind, intense eddy currents will occur, increasing wind noise, Also, running resistance increases. That is, in the case of a high-speed railway vehicle, if there is a space between the vehicles at the vehicle connecting portion, it causes a problem that wind noise and running resistance increase, which is a big problem. Therefore, in high-speed railway vehicles, it is a common practice to block the space between vehicles at a connecting portion that connects the front and rear vehicles with an outer hood device.

上記外幌装置の内、前後車両間の空間における車両側部間の空間を塞ぐ左右の側部外幌機構としては、例えば、前後車両の一方の車両の妻壁に固定されて車両側部間の空間の前記妻壁側の部分を塞ぐ固定外幌と、該固定外幌に隣接配置される第一可動外幌と、該第一可動外幌を前記固定外幌との整列位置と固定外幌の内方側に重なる縮退位置との間で変位可能に前記妻壁に支持する第一リンク機構と、前記固定外幌と反対側にて前記第一可動外幌に隣接配置される第二可動外幌と、該第二可動外幌を前記整列位置にある第一可動外幌との整列位置と第一可動外幌の内方側に重なる縮退位置との間で変位可能に前記第一可動幌の支持フレームに支持する第二リンク機構とを備えた三段シャッター式のものがある（例えば、特許文献１参照。）。 Among the outer hood devices, the left and right side outer hood mechanisms that close the space between the vehicle side portions in the space between the front and rear vehicles are, for example, fixed to the front wall of one vehicle of the front and rear vehicles and between the vehicle side portions. A fixed outer hood that closes a portion of the space on the side of the wife wall, a first movable outer hood disposed adjacent to the fixed outer hood, and an alignment position of the first movable outer hood with the fixed outer hood and a fixed outer A first link mechanism that is supported on the end wall so as to be displaceable between a retracted position overlapping the inner side of the hood, and a second link that is disposed adjacent to the first movable outer hood on the opposite side of the fixed outer hood. The first movable outer hood and the second movable outer hood are displaceable between an alignment position of the first movable outer hood in the aligned position and a degenerate position overlapping the inner side of the first movable outer hood. There is a three-stage shutter type equipped with a second link mechanism supported by a support frame of a movable hood (see, for example, Patent Document 1).

特開２００７−２８３８１２号公報JP 2007-283812 A

しかしながら、上記従来の外幌装置は、第一及び第二の可動外幌をそれぞれ第一及び第二のリンク機構で可動させることから、全体の構造が複雑になり、重量の面でも不利になる。また、シャッター可動用の僅かな隙間にも風が入り込むため、車両のさらなる高速化を考慮すると、可撓性を有する外幌でシャッター間を塞ぐ構成であることが望ましい。
他方、新幹線に対して車幅の狭い在来線規格の高速鉄道車両（新在直通車両）に上記のような外幌装置を採用する場合、狭まった車幅に適した構成が必要となる。すなわち、車両間の連結部には前後車両の妻面間に渡る通路が設けられ、この通路の左右にそれぞれ側部外幌機構が配設されることから、車幅が狭まった分だけ側部外幌機構の収容スペースが狭まると、通常は前記収容スペースの車両中心側から行うメンテナンス作業が困難になるという問題がある。 However, in the conventional outer hood device, the first and second movable outer hoods are moved by the first and second link mechanisms, respectively, so that the overall structure becomes complicated and disadvantageous in terms of weight. . In addition, since wind enters a small gap for moving the shutter, it is desirable that the shutter is closed with a flexible outer hood in consideration of further increase in vehicle speed.
On the other hand, when the above-described outer hood device is employed in a conventional high-speed railway vehicle (new direct train) having a narrower vehicle width than the Shinkansen, a configuration suitable for a narrow vehicle width is required. In other words, the connecting part between the vehicles is provided with a passage extending between the front and back of the front and rear faces of the vehicle, and side hood mechanisms are provided on the left and right sides of the passage respectively. When the storage space of the outer hood mechanism is narrowed, there is a problem that maintenance work usually performed from the vehicle center side of the storage space becomes difficult.

そこでこの発明は、高速鉄道車両の外幌装置において、車両左右の側部間の空間を塞ぐ左右の側部外幌機構のメンテナンス等を容易にすることを目的とする。 Accordingly, an object of the present invention is to facilitate maintenance of the left and right side outer hood mechanisms for closing the space between the left and right sides of the vehicle in the outer hood device for a high-speed railway vehicle.

本発明によれば、高速鉄道車両の直線走行状態では、固定外幌、可撓性外幌及び可動外幌が車体外側面とほぼ面一をなすように直列的に並ぶことで、前後車両間の空間の内の左右側部間の空間が隙間なく塞がれる。一方、高速鉄道車両の旋回走行状態では、該車両の一側部側にて前記空間が縮小されるが、このとき、リンク機構の動作により可動外幌が車両中心側へ変位し、かつこれに伴い可撓性外幌も車両中心側へ撓み変形することで、当該部位に隙間を生じさせることなく前記縮小が吸収される。このように、一組の可動外幌及びリンク機構と固定外幌及び可動外幌間に渡る可撓性外幌とにより、比較的簡単な構造で重量を抑えた上で、車両の左右側部間の空間を隙間なく塞ぐことができる。
そして、固定外幌及び可動外幌が、その車両外側から着脱可能な締結具を介して、前記一方の車両の妻面及びリンク機構にそれぞれ取り付けられることで、前記締結具を車両外側から着脱することにより、固定外幌及び可動外幌並びにこれらの間に渡る可撓性外幌を容易に着脱することができ、側部外幌機構のメンテナンス作業等を容易に行うことができる。
また、高速鉄道車両が直線走行状態から旋回走行状態に移行する際、リンク機構の動作により、可動側摺動板が固定側摺動板に摺接しつつ、可動外幌を車両中心側へ変位させることで、可動外幌と他方の車両の妻面との間に隙間を生じさせることなく、可動外幌をスムーズに車両中心側へ変位させることができる。また、側部外幌機構が一方の車両にのみ支持されることで、前後車両の連結・分離作業が連結器の連結・分離作業だけでよくなり、車両の連結・分離作業を簡単にできる。
そして、可動側摺動板の車両中心側の部位を固定側摺動板（他方の車両の妻面）から離間する側に反らせることで、リンク機構に可動側摺動板を取り付けた状態でもこれらを車両側部間の空間に着脱し易くなり、かつ不意の横風等の影響を受けて可動側摺動板が過大に摺動したとしてもこれを正規の摺動範囲に容易に復帰させることができる。
さらに、リンク機構がコンパクトなＸ字状リンクを構成することで、新幹線に対して車幅の狭い在来線規格の高速鉄道車両に当該外幌装置を採用した際にも、側部外幌機構の機構部分の収容スペースを容易に確保できる。
しかも、付勢手段の付勢力によりリンク機構を介して可動側摺動板を固定側摺動板側に付勢することで、高速鉄道車両が旋回走行状態から直線走行状態に戻った際に可動外幌と他方の車両の妻面との間に隙間が生じることを防止できると共に、側部外幌機構を着脱する際には、前記解除手段を用いて付勢手段の付勢力を解除することで、側部外幌機構の着脱を容易に行うことができる。
そして、固定外幌、可動外幌及び可撓性外幌の下部の車幅が抑えられ、当該外幌装置を前記在来線規格の高速鉄道車両に採用した際にも、車両下部における車両限界を侵すことなく、側部外幌機構の収容スペースを確保することができる。 According to the present invention, in a straight traveling state of a high-speed railway vehicle, the fixed outer hood, the flexible outer hood, and the movable outer hood are arranged in series so as to be substantially flush with the outer surface of the vehicle body. The space between the left and right sides of the space is closed without any gap. On the other hand, when the high-speed railway vehicle is turning, the space is reduced on one side of the vehicle. At this time, the movable outer hood is displaced toward the vehicle center by the operation of the link mechanism, and Accordingly, the flexible outer hood is also bent and deformed toward the center of the vehicle, so that the reduction can be absorbed without causing a gap in the portion. In this way, a pair of movable outer hood and link mechanism and a fixed outer hood and a flexible outer hood that spans between the movable outer hoods reduce the weight with a relatively simple structure and The space between them can be closed without gaps.
Then, the fixed outer hood and the movable outer hood are respectively attached to the wife surface and the link mechanism of the one vehicle via a fastener that can be attached and detached from the outside of the vehicle, so that the fastener is attached and detached from the outside of the vehicle. Thus, the fixed outer hood, the movable outer hood, and the flexible outer hood between them can be easily attached and detached, and the maintenance work and the like of the side outer hood mechanism can be easily performed.
Further, when the high-speed railway vehicle transitions from the straight traveling state to the turning traveling state, the movable outer hood is displaced toward the vehicle center side while the movable sliding plate is in sliding contact with the stationary sliding plate by the operation of the link mechanism. As a result, the movable outer hood can be smoothly displaced toward the vehicle center without causing a gap between the movable outer hood and the wife's face of the other vehicle. Further, since the side outer hood mechanism is supported by only one vehicle, the connection / separation work of the front and rear vehicles only needs to be the connection / separation work of the coupler, and the connection / separation work of the vehicle can be simplified.
And even if the movable side sliding plate is attached to the link mechanism, the movable side sliding plate is warped to the side away from the fixed side sliding plate (the other vehicle's face). Can be easily attached to and removed from the space between the side parts of the vehicle, and even if the movable side sliding plate slides excessively due to the influence of unexpected side wind, etc., it can be easily returned to the normal sliding range. it can.
In addition, since the link mechanism constitutes a compact X-shaped link, the side outer hood mechanism can be used even when the outer hood device is used in a conventional high-speed railway vehicle with a narrower vehicle width than the Shinkansen. It is possible to easily secure a storage space for the mechanism portion.
Moreover, the movable side sliding plate is urged to the fixed side sliding plate side via the link mechanism by the urging force of the urging means, so that the high-speed railway vehicle can move when it returns from the turning state to the linear state. It is possible to prevent a gap from being generated between the outer hood and the wife's face of the other vehicle, and to release the urging force of the urging means using the releasing means when the side outer hood mechanism is attached or detached. Therefore, the side outer hood mechanism can be easily attached and detached.
The vehicle width at the lower part of the fixed outer hood, the movable outer hood and the flexible outer hood is suppressed, and even when the outer hood device is adopted in the conventional line standard high-speed railway vehicle, It is possible to secure a storage space for the side outer hood mechanism without invading.

ここで、高速鉄道車両が直線走行状態から旋回走行状態（ポイント切り替え点の走行時等含む）となった際には、車両走行軌跡の内周側における車両側部間の空間４が縮小するが、このとき、当該部位に配される側部外幌機構６では、リンク機構１５の作用によりその後端側に支持した可動側摺動板２６及びこれに固定される可動外幌１３が車両中心側へ変位すると共に、この変位に追従するように可撓性外幌１４が撓み変形することで、当該側部外幌機構６が隙間を生じさせることなく前記側部間の空間４の縮小を吸収する。 Here, when the high-speed railway vehicle changes from a straight traveling state to a turning traveling state (including when traveling at a point switching point), the space 4 between the vehicle side portions on the inner peripheral side of the vehicle traveling locus is reduced. At this time, in the side outer hood mechanism 6 disposed in the part, the movable sliding plate 26 supported on the rear end side by the action of the link mechanism 15 and the movable outer hood 13 fixed thereto are arranged on the vehicle center side. And the flexible outer hood 14 bends and deforms so as to follow this displacement, so that the side outer hood mechanism 6 absorbs the reduction of the space 4 between the side portions without causing a gap. To do.

リンク機構１５は、平面視（上面視）で互いにＸ字状に交差する第一及び第二のリンク部材３２を備えてなる。第一のリンク部材３１は上下方向に沿う壁状をなし、この第一のリンク部材３１の上下に棒状の第二のリンク部材３２がそれぞれ配設される。第一のリンク部材３１の中間部の上下には回動軸３１ａが突設され、この上下回動軸３１ａがそれぞれ上下の第二のリンク部材３２の中間部に回動可能に係合する。なお、第一のリンク部材３１には、軽量化のための開口３１ｂが複数形成されている。 The link mechanism 15 includes first and second link members 32 that intersect each other in an X shape in plan view (top view). The first link member 31 has a wall shape extending in the vertical direction, and a rod-like second link member 32 is disposed above and below the first link member 31. Rotating shafts 31a project from the upper and lower portions of the intermediate portion of the first link member 31, and the upper and lower rotating shafts 31a engage with the intermediate portions of the upper and lower second link members 32, respectively. The first link member 31 has a plurality of openings 31b for weight reduction.

第一のリンク部材３１は、その一端部が前側車両２の妻面２ａの車両外側にて前記外ベースプレート２３上に固定された支持ブラケット３３に上下方向に沿う軸Ｊ１を介して回動可能に連結されると共に、他端部が前記可動側摺動板２６の車両中心側の裏面に突設された内連結部３５に上下方向に沿う軸Ｊ２を介して回動可能に連結される。 One end of the first link member 31 is rotatable on a support bracket 33 fixed on the outer base plate 23 on the outer side of the end surface 2a of the front vehicle 2 via an axis J1 along the vertical direction. In addition to being connected, the other end is rotatably connected to an inner connecting portion 35 projecting from the back surface of the movable side sliding plate 26 on the vehicle center side via an axis J2 extending in the vertical direction.

ここで、前記可動側摺動板２６は、後側車両３の妻面３ａに固定された該妻面３ａに沿う平板状の固定側摺動板２７に摺接するもので、この可動側摺動板２６の車両外側の部位は、固定側摺動板２７と平行な平板状をなすのに対し、車両中心側の部位は、その先端側ほど固定側摺動板２７から離間するように反った弧状の反り形状をなしている。この可動側摺動板２６の反り形状部２６ｃの先端側の内連結部３５に、前記第一のリンク部材３１の他端部が連結される。なお、可動側摺動板２６は、可動外幌１３の外側縁近傍から車両中心側へ所定幅で延びるもので、後面視で車両外側面に沿う逆Ｊ字形状をなしている。各摺動板２６，２７は、例えば金属板やＦＲＰ板等の剛性を有する板材で構成されている。 Here, the movable side sliding plate 26 is in sliding contact with a flat plate-like fixed side sliding plate 27 along the end surface 3 a fixed to the end surface 3 a of the rear vehicle 3. The portion on the vehicle outer side of the plate 26 has a flat plate shape parallel to the fixed side sliding plate 27, whereas the portion on the vehicle center side warps away from the fixed side sliding plate 27 toward the tip side. It has an arcuate warping shape. The other end portion of the first link member 31 is connected to the inner connection portion 35 on the distal end side of the warped shape portion 26 c of the movable side sliding plate 26. The movable side sliding plate 26 extends from the vicinity of the outer edge of the movable outer hood 13 to the vehicle center side with a predetermined width, and has an inverted J shape along the vehicle outer surface in a rear view. Each of the sliding plates 26 and 27 is made of a rigid plate material such as a metal plate or an FRP plate.

一方、第二のリンク部材３２は、その一端部が前側車両２の妻面２ａの車両中心側に配設されたスライド機構３６Ａのスライダ３６に上下方向に沿う軸Ｊ３を介して回動可能に連結されると共に、他端部が前記可動側摺動板２６の車両外側の裏面に突設された外連結部３５ａに上下方向に沿う軸Ｊ４を介して回動可能に連結される。 On the other hand, the second link member 32 is rotatable at one end thereof to the slider 36 of the slide mechanism 36A disposed on the vehicle center side of the front surface 2a of the front vehicle 2 via an axis J3 along the vertical direction. While being connected, the other end is rotatably connected to an outer connecting portion 35a provided on the rear surface of the movable side sliding plate 26 on the outer side of the vehicle via an axis J4 along the vertical direction.

ここで、スライダ３６機構は、前側車両２の妻面２ａに内ベースプレート３４を介して固定された左右方向（車幅方向）に沿うガイドレール３７に、前記スライダ３６を左右方向でスライド可能に支持してなる。このスライダ３６に軸支される第二のリンク部材３２の一端部は、前述の如く回動可能であると共に、車幅方句で移動可能に前側車両２の妻面２ａに支持されるといえる。 Here, the slider 36 mechanism supports the slider 36 slidably in the left-right direction on a guide rail 37 extending in the left-right direction (vehicle width direction) fixed to the end surface 2a of the front vehicle 2 via the inner base plate 34. Do it. One end portion of the second link member 32 pivotally supported by the slider 36 can be rotated as described above, and can be supported by the front surface 2a of the front vehicle 2 so as to be movable in the vehicle width phrase. .

可動側摺動板２６の外連結部３５ａは、車幅方向に長い長孔３９を有し、この長孔３９に第二のリンク部材３２の他端部が前記軸Ｊ４及びこれを挿通するローラ３８を介して移動可能に連結される。これにより、第二のリンク部材３２の他端部は、前述の如く回動可能であると共に、車幅方向で移動可能に可動側摺動板２６に支持されるといえる。なお、前記長孔３９は、車両外側ほど前側に位置するように傾斜しており、したがって第二のリンク部材３２の他端部は、前後方向でも移動可能に可動側摺動板２６に支持されるといえる。 The outer connecting portion 35a of the movable sliding plate 26 has a long hole 39 that is long in the vehicle width direction, and the other end portion of the second link member 32 is inserted into the long hole 39 through the shaft J4 and the roller. It is movably connected via 38. Accordingly, it can be said that the other end portion of the second link member 32 is supported by the movable sliding plate 26 so as to be rotatable as described above and movable in the vehicle width direction. The long hole 39 is inclined so as to be located on the front side toward the outer side of the vehicle. Therefore, the other end portion of the second link member 32 is supported by the movable side sliding plate 26 so as to be movable also in the front-rear direction. It can be said.

支持ブラケット３３の近傍には取り付け部３３ａが固定的に設けられ、この取り付け部３３ａとスライダ３６との間には、リンク機構１５を介して可動側摺動板２６を後側車両３の妻面３ａ側に付勢する付勢装置４１が設けられる。付勢装置４１は、左右方向に沿って延在する棒状のもので、取り付け部３３ａに上下方向に沿う軸Ｊ５を介して回動可能に連結される外端部４１ａと、スライダ３６に前記軸Ｊ３を介して回動可能に連結される内端部４１ｂと、両端部４１ａ，４１ｂ間に所定の初期張力をもって張設される引張りコイルスプリング４１ｃとを一体的に有する。この付勢装置４１の付勢力により、スライダ３６が取り付け部３３ａ側（支持ブラケット３３側）に引かれるように付勢され、もって可動側摺動板２６が後側車両３の妻面３ａ側に押し付けられるように付勢される。 An attachment portion 33a is fixedly provided in the vicinity of the support bracket 33, and the movable-side sliding plate 26 is interposed between the attachment portion 33a and the slider 36 via the link mechanism 15 and is a face of the rear vehicle 3. A biasing device 41 that biases toward the 3a side is provided. The urging device 41 is a rod-shaped member extending in the left-right direction, and an outer end portion 41a that is rotatably connected to the attachment portion 33a via an axis J5 along the vertical direction, and the slider 36 is connected to the shaft. An inner end portion 41b that is rotatably connected via J3 and a tension coil spring 41c that is stretched between the both end portions 41a and 41b with a predetermined initial tension are integrally provided. The urging force of the urging device 41 urges the slider 36 so as to be pulled toward the mounting portion 33a (support bracket 33 side), so that the movable sliding plate 26 moves toward the end surface 3a of the rear vehicle 3. It is energized to be pressed.

ここで、図１，２に示すように、高速鉄道車両の車体は、その上部に対して下部が車両中心側へ変化するように滑らかに湾曲しており、これに伴い、固定外幌１２、可動外幌１３及び可撓性外幌１４も、その上部に対して下部が車両中心側へ変化するように滑らかに湾曲して設けられる。これにより、前後車両２，３の連結部９下側の車幅（左右幅）が抑えられ、在来線規格の高速鉄道車両に当該外幌装置１を採用した場合でも、車両下部における車両限界を侵すことなく、側部外幌機構６の特に機構部分の収容スペースを広く確保することができる。 Here, as shown in FIGS. 1 and 2, the body of the high-speed railway vehicle is smoothly curved so that the lower portion changes toward the vehicle center side with respect to the upper portion. The movable outer hood 13 and the flexible outer hood 14 are also provided so as to be smoothly curved so that the lower portion changes toward the vehicle center side with respect to the upper portion. As a result, the vehicle width (left-right width) below the connecting portion 9 of the front and rear vehicles 2 and 3 is suppressed, and even when the outer hood device 1 is used in a conventional high-speed railway vehicle, the vehicle limit at the lower part of the vehicle Without encroaching on the side, it is possible to secure a wide accommodation space particularly in the mechanism portion of the side outer hood mechanism 6.

図６（ａ）を参照し、高速鉄道車両の直線走行状態において、固定外幌本体１２ａ、可撓性外幌１４及び可動外幌本体１３ａは、前記付勢装置４１の付勢力により、互いに面一状に整列した初期状態に保持される。これにより、前後車両２，３の連結部９における車両側部間の空間４が塞がれ、当該部位における風切り騒音や走行抵抗力が低減される。 Referring to FIG. 6A, in the straight traveling state of the high-speed railway vehicle, the fixed outer hood main body 12a, the flexible outer hood 14 and the movable outer hood main body 13a face each other by the urging force of the urging device 41. It is maintained in an initial state aligned in a single shape. Thereby, the space 4 between the vehicle side parts in the connection part 9 of the front and rear vehicles 2 and 3 is closed, and wind noise and travel resistance at the part are reduced.

一方、高速鉄道車両が直線走行状態から旋回走行状態に移行した際には、車両走行軌跡の内周側における車両側部間の空間４が縮小するが、この縮小は、付勢装置４１の付勢力に抗して可動側摺動板２６が前側車両２の妻面２ａ側に変位しつつ固定側摺動板２７上を摺動し、可動側摺動板２６及び可動外幌１３が車両中心側へ変位すると共に、この変位に追従するように可撓性外幌１４が撓み変形することで、当該部位に隙間を生じさせることなく前記側部間の空間４の縮小が吸収される。 On the other hand, when the high-speed railway vehicle transitions from the straight traveling state to the turning traveling state, the space 4 between the vehicle side portions on the inner periphery side of the vehicle traveling locus is reduced. The movable side sliding plate 26 slides on the stationary side sliding plate 27 while being displaced toward the front surface 2a side of the front vehicle 2 against the force, and the movable side sliding plate 26 and the movable outer hood 13 are located in the center of the vehicle. When the flexible outer hood 14 is deformed so as to follow the displacement, the reduction of the space 4 between the side portions is absorbed without causing a gap in the portion.

図６（ｂ）を参照し、前記側部間の空間４が縮小すると、第一のリンク部材３１の傾動により可動側摺動板２６が車両中心側へ移動する。このとき、回動軸３１ａを介して第二のリンク部材３２も車両中心側へ移動することで、スライダ３６が車両中心側へ移動すると共に、第二のリンク部材３２の傾動により軸Ｊ４及びローラ３８が長孔３９内を車両外側かつやや前側へ移動する。 Referring to FIG. 6B, when the space 4 between the side portions is reduced, the movable side sliding plate 26 moves to the vehicle center side by the tilting of the first link member 31. At this time, the second link member 32 also moves to the vehicle center side via the rotation shaft 31a, so that the slider 36 moves to the vehicle center side, and the shaft J4 and the roller are tilted by the tilt of the second link member 32. 38 moves inside the long hole 39 to the outside of the vehicle and slightly to the front.

図６（ｃ）〜（ｅ）を参照し、前記側部間の空間４がさらに縮小すると、可動外幌１３が固定外幌１２の内方側に入り込むように移動し、これに伴い可撓性外幌１４も大きく撓み変形するが、当該部位に隙間が生じることはない。 6 (c) to 6 (e), when the space 4 between the side portions is further reduced, the movable outer hood 13 moves so as to enter the inner side of the fixed outer hood 12, and accordingly, the flexible The outer outer hood 14 is also greatly bent and deformed, but there is no gap at the site.

一方、高速鉄道車両が旋回走行状態から直進走行状態に戻る際には、前述の動作とは逆の動きで可動側摺動板２６、リンク機構１５及び可動外幌１３が初期状態（直進走行状態）に戻る。このときの逆の動きは、前記付勢装置４１の付勢力によってなされる。 On the other hand, when the high-speed railway vehicle returns to the straight traveling state from the turning traveling state, the movable side sliding plate 26, the link mechanism 15 and the movable outer hood 13 are in the initial state (straight traveling state) with the reverse movement to the above-described operation. Return to). The reverse movement at this time is made by the urging force of the urging device 41.

ここで、図５に示すように、固定外幌本体１２ａ、可動外幌本体１３ａ及び可撓性外幌１４は、前記締結ボルト２４，２８により車両外側から着脱可能に取り付けられており、例えばリンク機構１５等のメンテナンスを行う際には、前記締結ボルト２４，２８を車両外側から取り外して固定外幌本体１２ａ、可動外幌本体１３ａ及び可撓性外幌１４を一体的に取り外すことで（図５（ｂ）参照）、車両側部間の空間４が車両外側に開放されてアクセス可能となり、側部外幌機構６のメンテナンスや組み付け等を容易に行うことができる。なお、図中符号１２ａ，１３ａは固定外幌本体１２ａ及び可動外幌本体１３ａの前後の位置決めを行うリブを、符号１２ｃ，１３ｃは固定外幌本体１２ａ及び可動外幌本体１３ａと各フレーム２１，２２の側壁部２１ａ，２２ａとの間に配されるクッション材をそれぞれ示す。 Here, as shown in FIG. 5, the fixed outer hood main body 12a, the movable outer hood main body 13a, and the flexible outer hood 14 are detachably attached from the outside of the vehicle by the fastening bolts 24, 28. When performing maintenance of the mechanism 15 and the like, the fastening bolts 24 and 28 are removed from the outside of the vehicle, and the fixed outer hood main body 12a, the movable outer hood main body 13a, and the flexible outer hood 14 are integrally removed (see FIG. 5 (b)), the space 4 between the side portions of the vehicle is opened to the outside of the vehicle and can be accessed, so that the maintenance and assembly of the side outer hood mechanism 6 can be easily performed. In the figure, reference numerals 12a and 13a denote ribs for positioning the fixed outer hood main body 12a and the movable outer hood main body 13a before and after, and reference numerals 12c and 13c denote fixed outer hood main body 12a and movable outer hood main body 13a and the respective frames 21, The cushioning material distribute | arranged between 22 side wall parts 21a and 22a is each shown.

また、可動側摺動板２６の車両中心側の部位が固定側摺動板２７から離間するように反り形状をなすことで、該可動側摺動板２６を取り付けた状態のリンク機構１５を車両側部間の空間４に挿入し易くなると共に、横風等の影響で可動側摺動板２６が過大に摺動したとしても、該可動側摺動板２６が正規の摺動位置へ復帰し易くなる。さらに、第一のリンク部材３１の他端部が可動側摺動板２６の反り形状の先端側に連結されることで、第一のリンク部材３１の長さが短縮されて軽量化が図られる。 Further, by forming a warped shape so that a portion of the movable side sliding plate 26 on the vehicle center side is separated from the fixed side sliding plate 27, the link mechanism 15 with the movable side sliding plate 26 attached thereto is mounted on the vehicle. It becomes easy to insert into the space 4 between the side portions, and even if the movable side sliding plate 26 slides excessively due to the influence of a cross wind or the like, the movable side sliding plate 26 easily returns to the normal sliding position. Become. Furthermore, the other end of the first link member 31 is connected to the warped tip side of the movable sliding plate 26, whereby the length of the first link member 31 is shortened and the weight is reduced. .

図７に示すように、前記付勢装置４１の両端部４１ａ，４１ｂとスライダ３６及び取り付け部３３ａとの各連結部（図では付勢装置４１の両端部４１ａ，４１ｂ）には、付勢装置４１の付勢力を解除するための解除装置４２の取り付け部４３がそれぞれ設けられる。なお、付勢装置４１の外端部４１ａ及び取り付け部３３ａを、付勢装置４１と支持ブラケット３３との連結部とみなすこともできる。 As shown in FIG. 7, the urging device includes a connecting portion (both ends 41 a and 41 b of the urging device 41) between the both ends 41 a and 41 b of the urging device 41 and the slider 36 and the mounting portion 33 a. Attachment portions 43 of release devices 42 for releasing the urging force of 41 are provided. Note that the outer end portion 41 a and the attachment portion 33 a of the urging device 41 can be regarded as a connecting portion between the urging device 41 and the support bracket 33.

解除装置４２は、付勢装置４１と略平行に延在する棒状のターンバックルであり、前記各取り付け部４３に着脱可能に締結される一対の端部４２ａと、該各端部４２ａの一方から他方側へ延びる一対のネジ軸４２ｂと、該各ネジ軸４２ｂを両端部に螺合する胴体枠４２ｃとを有してなる。各ネジ軸４２ｂの一方は逆ネジとされ、前記胴体枠４２ｃを各ネジ軸４２ｂ中心に回転させることで、各端部４２ａ間の距離を増減可能である。 The release device 42 is a rod-shaped turnbuckle extending substantially parallel to the urging device 41, and includes a pair of end portions 42a that are detachably fastened to the attachment portions 43, and one of the end portions 42a. It has a pair of screw shafts 42b extending to the other side, and a body frame 42c for screwing the screw shafts 42b to both ends. One of the screw shafts 42b is a reverse screw, and the distance between the end portions 42a can be increased or decreased by rotating the body frame 42c about the screw shafts 42b.

そして、リンク機構１５の着脱等の作業時には、解除装置４２により付勢装置４１を短縮させてリンク機構１５の前後幅を圧縮し、この状態で車両側部間の空間４にリンク機構１５を着脱することで、側部外幌機構６のメンテナンスや組み付け等を容易に行うことができる。なお、リンク機構１５の組み付け後には、解除装置４２を取り外して可動側摺動板２６を固定側摺動板２７側に付勢すればよい。また、取り付け部４３はスライダ３６や取り付け部３３ａに設けてもよい。 During work such as attachment / detachment of the link mechanism 15, the biasing device 41 is shortened by the release device 42 to compress the front / rear width of the link mechanism 15, and the link mechanism 15 is attached / detached to the space 4 between the vehicle side parts in this state. By doing so, the maintenance, assembly, etc. of the side outer hood mechanism 6 can be easily performed. After the link mechanism 15 is assembled, the release device 42 may be removed and the movable side sliding plate 26 may be biased toward the fixed side sliding plate 27 side. Further, the attachment portion 43 may be provided on the slider 36 or the attachment portion 33a.

前記固定外幌本体１２ａ及び可動外幌本体１３ａは、前記締結ボルト２４，２８によって、前記固定側フレーム２１及び可動側フレーム２２にそれぞれ取り付けられている。
また、前記固定外幌１２、可動外幌１３及び可撓性外幌１４は、これらが互いに連結された状態で、前記締結ボルト２４，２８の着脱により、前側車両２の妻面２ａ及びリンク機構１５に対して着脱可能とされている。 Here, the fixed outer hood 12 has a fixed frame 21 attached to the front surface 2a of the front vehicle 2 and a fixed outer hood main body 12a attached to the outer edge of the fixed frame 21.
The movable outer hood 13 is attached to a movable side frame 22 in contact with the end face 3a of the rear vehicle 3 via a movable side sliding plate 26 supported by the link mechanism 15 and an outer edge of the movable side frame 22. A movable outer hood main body 13a,
The fixed outer hood main body 12a and the movable outer hood main body 13a are attached to the fixed frame 21 and the movable frame 22 by the fastening bolts 24 and 28, respectively.
In addition, the fixed outer hood 12, the movable outer hood 13, and the flexible outer hood 14 are connected to each other, and the fastening surface 24 and 28 are attached to and detached from the front surface 2a of the front vehicle 2 and the link mechanism. 15 is detachable.

この構成によれば、高速鉄道車両の直線走行状態では、固定外幌１２、可撓性外幌１４及び可動外幌１３が車体外側面とほぼ面一をなすように直列的に並ぶことで、前後車両２，３間の空間９ａの内の左右側部間の空間４が隙間なく塞がれる。一方、高速鉄道車両の旋回走行状態では、該車両の一側部側にて前記空間４が縮小されるが、このとき、リンク機構１５の動作により可動外幌１３が車両中心側へ変位し、かつこれに伴い可撓性外幌１４も車両中心側へ撓み変形することで、当該部位に隙間を生じさせることなく前記縮小が吸収される。このように、一組の可動外幌１３及びリンク機構１５と、固定外幌１２及び可動外幌１３間に渡る可撓性外幌１４とにより、比較的簡単な構造で重量を抑えた上で、車両の左右側部間の空間４を隙間なく塞ぐことができる。
そして、固定外幌１２及び可動外幌１３が、その車両外側から着脱可能な締結ボルト２４，２８を介して、前側車両２の妻面２ａ及びリンク機構１５にそれぞれ取り付けられることで、前記締結ボルト２４，２８を車両外側から着脱することにより、固定外幌１２及び可動外幌１３並びにこれらの間に渡る可撓性外幌１４を容易に着脱することができ、側部外幌機構５，６のメンテナンス作業等を容易に行うことができる。 According to this configuration, in the straight traveling state of the high-speed railway vehicle, the fixed outer hood 12, the flexible outer hood 14 and the movable outer hood 13 are arranged in series so as to be substantially flush with the outer surface of the vehicle body. The space 4 between the left and right side portions in the space 9a between the front and rear vehicles 2 and 3 is closed without a gap. On the other hand, in the turning state of the high-speed railway vehicle, the space 4 is reduced on one side of the vehicle. At this time, the movable outer hood 13 is displaced toward the vehicle center side by the operation of the link mechanism 15. In addition, the flexible outer hood 14 is also bent and deformed toward the center of the vehicle, so that the reduction is absorbed without causing a gap in the portion. As described above, the weight of the movable outer hood 13 and the link mechanism 15 and the flexible outer hood 14 extending between the fixed outer hood 12 and the movable outer hood 13 is reduced with a relatively simple structure. The space 4 between the left and right sides of the vehicle can be closed without a gap.
And the fixed outer hood 12 and the movable outer hood 13 are respectively attached to the end face 2a of the front vehicle 2 and the link mechanism 15 via fastening bolts 24 and 28 that can be attached and detached from the outside of the vehicle. By attaching and detaching 24 and 28 from the outside of the vehicle, the fixed outer hood 12 and the movable outer hood 13 and the flexible outer hood 14 between them can be easily attached and detached. The maintenance work can be easily performed.

この構成によれば、高速鉄道車両が直線走行状態から旋回走行状態に移行する際、リンク機構１５の動作により、可動側摺動板２６が固定側摺動板２７上に摺接しつつ、可動外幌１３を車両中心側へ変位させることで、可動外幌１３と後側車両３の妻面３ａとの間に隙間を生じさせることなく、可動外幌１３をスムーズに車両中心側へ変位させることができる。また、側部外幌機構５，６が前側車両２にのみ支持されることで、前後車両２，３の連結・分離作業が連結器の連結・分離作業だけでよくなり、車両の連結・分離作業を簡単にできる。
そして、可動側摺動板２６の車両中心側の部位を固定側摺動板２７（後側車両３の妻面３ａ）から離間する側に反らせることで、リンク機構１５に可動側摺動板２６を取り付けた状態でもこれらを車両側部間の空間４に着脱し易くなり、かつ不意の横風等の影響を受けて可動側摺動板２６が過大に摺動したとしてもこれを正規の摺動範囲に容易に復帰させることができる。 Further, in the outer hood device 1, the movable outer hood 13 includes a movable sliding plate 26 extending from the outer edge on the rear vehicle 3 side to the vehicle center side, and on the wife surface 3a of the rear vehicle 3, A fixed-side sliding plate 27 that is in sliding contact with the movable-side sliding plate 26 is provided, and a portion of the movable-side sliding plate 26 on the vehicle center side is warped so as to be separated from the fixed-side sliding plate 27. It is what is done.
According to this configuration, when the high-speed railway vehicle transitions from the straight traveling state to the turning traveling state, the movable side sliding plate 26 is in sliding contact with the fixed side sliding plate 27 by the operation of the link mechanism 15, and is not movable. By displacing the hood 13 toward the center of the vehicle, the movable hood 13 can be smoothly displaced toward the center of the vehicle without creating a gap between the movable outer hood 13 and the end face 3a of the rear vehicle 3. Can do. Further, since the side outer hood mechanisms 5 and 6 are supported only by the front vehicle 2, the connecting and separating operations of the front and rear vehicles 2 and 3 need only be the connecting and separating operations of the coupler, and the connecting and separating of the vehicles. Easy work.
Then, the movable side sliding plate 26 is warped toward the side away from the fixed side sliding plate 27 (the end surface 3a of the rear vehicle 3) of the movable side sliding plate 26, thereby causing the link mechanism 15 to move the movable side sliding plate 26. These can be easily attached to and detached from the space 4 between the side portions of the vehicle, and even if the movable side sliding plate 26 slides excessively due to the influence of the unexpected side wind, etc. Can be easily returned to range.

また、上記外幌装置１は、前記リンク機構１５が、平面視で互いにＸ字状に交差する第一及び第二のリンク部材３１，３２を備え、前記第一のリンク部材３１は、その一端部が前側車両２の妻面２ａ側に回動可能に支持されると共に、他端部が前記可動側摺動板２６の反り形状の先端側に回動可能に支持され、前記第二のリンク部材３２は、その一端部が前側車両２の妻面２ａ側に回動可能かつ車幅方向で移動可能に支持されると共に、他端部が前記可動側摺動板２６に回動可能かつ車幅方向で移動可能に支持されるものである。
この構成によれば、リンク機構１５がコンパクトなＸ字状リンクを構成することで、新幹線に対して車幅の狭い在来線規格の高速鉄道車両に当該外幌装置１を採用した際にも、側部外幌機構５，６の機構部分の収容スペースを容易に確保できる。 Further, the outer hood device 1 includes first and second link members 31 and 32 in which the link mechanism 15 intersects with each other in an X shape in plan view, and the first link member 31 has one end thereof. The second link is rotatably supported on the front surface 2a side of the front vehicle 2 and the other end is rotatably supported on the warped tip end side of the movable side sliding plate 26. One end of the member 32 is supported so as to be rotatable toward the end surface 2a of the front vehicle 2 and movable in the vehicle width direction, and the other end thereof is rotatable to the movable sliding plate 26. It is supported so as to be movable in the width direction.
According to this configuration, the link mechanism 15 forms a compact X-shaped link, so that when the outer hood device 1 is employed in a conventional high-speed railway vehicle having a narrower vehicle width than the Shinkansen, In addition, it is possible to easily secure an accommodation space for the mechanism portions of the side outer hood mechanisms 5 and 6.

また、上記外幌装置１は、前記リンク機構１５が、前側車両２の妻面２ａ側に前記第一のリンク部材３１の一端部を回動可能に支持する支持ブラケット３３と、前側車両２の妻面２ａ側に前記第二のリンク部材３２の一端部を回動可能かつ車幅方向で移動可能に支持するスライダ３６とを有し、前記支持ブラケット３３近傍の取り付け部３３ａ及びスライダ３６の間には、これらを互いに接近する側に付勢する付勢装置４１が渡設され、前記付勢装置４１と取り付け部３３ａ及びスライダ３６との各連結部（各端部４１ａ，４１ｂ）には、それぞれ前記付勢装置４１の付勢力を解除する解除装置４２の取り付け部４３が設けられるものである。
この構成によれば、付勢装置４１の付勢力によりリンク機構１５を介して可動側摺動板２６を固定側摺動板２７側に付勢することで、高速鉄道車両が旋回走行状態から直線走行状態に戻った際に、可動外幌１３と後側車両３の妻面３ａとの間に隙間が生じることを防止できると共に、側部外幌機構５，６を着脱する際には、前記解除手段を用いて付勢装置４１の付勢力を解除することで、側部外幌機構５，６の着脱を容易に行うことができる。 In the outer hood device 1, the link mechanism 15 includes a support bracket 33 that rotatably supports one end portion of the first link member 31 on the end face 2 a side of the front vehicle 2, and a front vehicle 2. And a slider 36 that supports one end of the second link member 32 so as to be rotatable and movable in the vehicle width direction on the side of the end face 2 a, and between the mounting portion 33 a and the slider 36 in the vicinity of the support bracket 33. The urging device 41 for urging them toward each other is handed over, and each connecting portion (each end portion 41a, 41b) between the urging device 41 and the mounting portion 33a and the slider 36 is provided with Each is provided with a mounting portion 43 of a release device 42 for releasing the biasing force of the biasing device 41.
According to this configuration, the movable side sliding plate 26 is urged to the fixed side sliding plate 27 side via the link mechanism 15 by the urging force of the urging device 41, so that the high-speed railway vehicle is straight from the turning state. When returning to the running state, it is possible to prevent a gap from being generated between the movable outer hood 13 and the end face 3a of the rear vehicle 3, and when the side outer hood mechanisms 5 and 6 are attached and detached, By releasing the urging force of the urging device 41 using the releasing means, the side outer hood mechanisms 5 and 6 can be easily attached and detached.

また、上記外幌装置１は、前記固定外幌１２、可動外幌１３及び可撓性外幌１４の下部が、車両中心側へ変化するように設けられるものである。
この構成によれば、固定外幌１２、可動外幌１３及び可撓性外幌１４の下部の車幅が抑えられ、当該外幌装置１を前記在来線規格の高速鉄道車両に採用した際にも、車両下部における車両限界を侵すことなく、側部外幌機構５，６の収容スペースを確保することができる。 The outer hood device 1 is provided such that lower portions of the fixed outer hood 12, the movable outer hood 13, and the flexible outer hood 14 change toward the vehicle center side.
