Description

鉄道車両構体Railway vehicle structure
　本発明は、鉄道車両構体に関する。 The present invention relates to a railway vehicle structure.
　一般的に、鉄道車両構体は床面をなす台枠と、台枠の幅方向の両端部に立設される側構体と、台枠の長手方向の両端部に立設される妻構体と、側構体および妻構体の上端部に載置される屋根構体からなる６面体で形成されている。 In general, a railway vehicle structure is a base frame that forms a floor surface, side structures that are erected at both ends in the width direction of the frame, and wife structures that are erected at both ends in the longitudinal direction of the frame, It is formed of a hexahedron composed of a roof structure placed on the upper ends of the side structure and the wife structure.
　そして、鉄道車両構体の製造において、部品点数が少なく製作工数を小さくするために、押出成形した複数の部材を利用する場合がある。この場合、アルミニウム合金を鉄道車両構体の長手方向に押出成形した複数の中空押出形材を接合して鉄道車両構体を構成する台枠や側構体や屋根構体を製造する。 In manufacturing a railway vehicle structure, a plurality of extruded members may be used to reduce the number of parts and the number of manufacturing steps. In this case, a plurality of hollow extruded shapes obtained by extruding aluminum alloy in the longitudinal direction of the railway vehicle structure are joined to produce a frame, a side structure, and a roof structure constituting the railway vehicle structure.
　また、鉄道車両が曲線や渡り線を通過する際に、鉄道車両の長手方向の端部の幅方向の最大寸法が車両限界の範囲内に収まるように、側構体の長手方向の端部の幅方向寸法を小さく設計する場合がある。こうした場合には、特許文献１に開示されているように、鉄道車両構体の長手方向の端部の幅方向寸法を小さく設計している。 In addition, when the railway vehicle passes a curve or a crossover, the width of the end portion in the longitudinal direction of the side structure is set so that the maximum dimension in the width direction of the longitudinal end portion of the railway vehicle is within the vehicle limit range. The direction dimension may be designed to be small. In such a case, as disclosed in Patent Document 1, the width direction dimension of the end portion in the longitudinal direction of the railway vehicle structure is designed to be small.

　鉄道車両構体の幅方向の寸法がその長手方向において変化しない場合は、側構体を側構体の長手方向の長さを有する中空押出形材で容易に製造することができる。しかし、鉄道車両構体の長手方向の端部の幅方向寸法をその中央部の幅方向寸法より小さくする場合には側構体の全てを側構体の長手方向の長さを有する中空押出形材で製造するのは容易でない。何故ならば、対向する２枚の面板を複数のリブで接続した中空押出形材は、その曲げ剛性が大きいため、曲げ加工等が容易に行えないからである。 When the dimension in the width direction of the railway vehicle structure does not change in the longitudinal direction, the side structure can be easily manufactured with a hollow extruded shape having a length in the longitudinal direction of the side structure. However, when the widthwise dimension of the longitudinal end of the railway vehicle structure is made smaller than the widthwise dimension of the central part, all of the side structures are manufactured with a hollow extruded shape having the length of the side structure in the longitudinal direction. It is not easy to do. This is because a hollow extruded shape member in which two facing face plates are connected by a plurality of ribs has a large bending rigidity, so that bending work or the like cannot be easily performed.
　このため、鉄道車両構体の幅方向の寸法が端部において変化する場合には側構体を、その長手方向中央部の中央部構造体と、その長手方向端部の端部構造体に分割して製造している。つまり６面体で形成される鉄道車両構体を台枠、中央部構造体、端部側構体、妻構体、屋根構体を溶接等で接合して製造している。このような製造工程においては、端部側構体は、中央部構造体及び屋根構体、台枠、妻構体の４部材と整合して取り付けなければならないため、製造工程が複雑であった。 For this reason, when the width direction dimension of the railway vehicle structure changes at the end, the side structure is divided into a central structure at the center in the longitudinal direction and an end structure at the end in the longitudinal direction. Manufacture. In other words, a railcar structure formed of hexahedrons is manufactured by joining a frame, a central structure, an end-side structure, a wife structure, and a roof structure by welding or the like. In such a manufacturing process, the end side structure has to be attached in alignment with the four members of the center structure, the roof structure, the underframe, and the end structure, and thus the manufacturing process is complicated.
　本発明の目的は、中央部側構体と端部側構体から構成される側構体を有する鉄道車両構体において、中央部側構体と端部側構体の接合部を容易に位置決めでき、鉄道車両構体を容易かつ確実に製造可能な構成を備える鉄道車両構体を提供することである。 An object of the present invention is to provide a railway vehicle structure having a side structure composed of a central portion side structure and an end portion side structure, and can easily position a joint portion between the central portion side structure and the end portion side structure. It is an object of the present invention to provide a railway vehicle structure having a configuration that can be easily and reliably manufactured.
　上記目的を達成するため、代表的な本発明の鉄道車両構体の一つは、床面をなす台枠と、側面をなす側構体と、前記側構体の上端部に載置される屋根構体とを有する鉄道車両構体において、前記側構体は、前記側構体の長手方向の中央部に備えられる中央部側構体と、前記中央部側構体の長手方向の端部に備えられる端部側構体とを有しており、前記中央部側構体は、高さ方向の上端部に、前記側構体の長手方向の端部に至るまで延伸する延伸部を有し、前記延伸部の下部に前記端部側構体が設けられていることを特徴とする。 In order to achieve the above object, one of the representative railway vehicle structures of the present invention includes a base frame that forms a floor, a side structure that forms a side surface, and a roof structure that is placed on the upper end of the side structure. In the railway vehicle structure, the side structure includes a central portion side structure provided at a central portion in the longitudinal direction of the side structure and an end portion side structure provided at an end portion in the longitudinal direction of the central portion side structure. The central part side structure has an extension part extending up to an end part in the longitudinal direction of the side structure at an upper end part in the height direction, and the end part side at a lower part of the extension part A structure is provided.
　本発明によれば、中央部側構体と端部側構体とから構成される側構体を有する鉄道車両構体において、中央部側構体と端部側構体の接合を容易かつ確実に行うことができる。 According to the present invention, in a railway vehicle structure having a side structure composed of a center part structure and an end part structure, the center part structure and the end part structure can be easily and reliably joined.

Similarly, the extending portion 23 of the central portion side structure 22 is also configured by a hollow extruded shape member. Here, the center portion side structure 22 is manufactured by arranging a plurality of hollow extruded shapes extruded in the X direction on a surface plate, and abutting and joining the ends in the Z direction of the hollow extruded shapes. Is done. That is, as shown in FIGS. 1 to 3, the center side structure 22 is assembled in a panel shape in which a plurality of hollow extruded shapes are arranged in the Z direction. The central structure 22 is provided with a window opening 21 and a side opening (not shown) for passengers to get on and off.
　図３に示されるように中央部側構体２２は、Ｚ方向上側から順に２０ａ～２０ｆの６つの中空押出形材で形成されている。そして、Ｚ方向の上端部の中空押出形材２０ａには、側構体２０の端部に向けてＸ方向に延びる延伸部２３を備えている。そしてこの延伸部２３は、側構体２０のＸ方向の一方の端部から他方の端部（側構体２０の全長に至るまで）に渡って形成されている。また、中央部側構体２２において延伸部２３の下部分は、切り欠いた切欠き部６０となっており、この切欠き部６０に端部側構体２４が接続される。 As shown in FIG. 3, the central structure 22 is formed of six hollow extruded members 20a to 20f in order from the upper side in the Z direction. The hollow extruded shape member 20 a at the upper end portion in the Z direction is provided with an extending portion 23 that extends in the X direction toward the end portion of the side structure 20. The extending portion 23 is formed from one end of the side structure 20 in the X direction to the other end (until the entire length of the side structure 20). Further, the lower portion of the extending portion 23 in the central portion side structure 22 is a notched portion 60, and the end portion side structure 24 is connected to the notched portion 60.
　図３に示される実施形態においては、延伸部２３は、中央部側構体２２のＺ方向の上端部の中空押出形材２０ａの一部が側構体２０のＸ方向に延伸して形成されている。しかし、延伸部２３のＺ方向の長さは任意に変更可能であり、中空押出形材２０ａ全体が延伸部２３となる構成でもよい。さらに、延伸部２３は、中空押出形材２０ａの全体及びその下部の中空押出形材２０ｂや２０ｃ等を含むように構成されてもよい。 In the embodiment shown in FIG. 3, the extending portion 23 is formed by extending a part of the hollow extruded shape member 20 a at the upper end portion in the Z direction of the central side structure 22 in the X direction of the side structure 20. . However, the length of the extending portion 23 in the Z direction can be arbitrarily changed, and the entire hollow extruded shape member 20 a may be the extending portion 23. Furthermore, the extending | stretching part 23 may be comprised so that the hollow extrusion shape material 20a whole and the hollow extrusion shape materials 20b and 20c of the lower part may be included.
　図３に示されるように、延伸部２３が中空押出形材２０ａの一部として形成された場合には、中空押出形材２０ａの下側には、中空押出形材２０ａ以外の中空押出形材（２０ｂ、２０ｃ、２０ｄ、２０ｅ、２０ｆ）がＺ方向に並んで接続される。この場合これらの中空押出形材（２０ｂ、２０ｃ、２０ｄ、２０ｅ、２０ｆ）におけるＸ方向の寸法は、側構体２０の長手方向の寸法に比べて端部側構体２４のＸ方向の寸法分だけ小さく設定されている。つまり、中空押出形材２０ａ以外の中空押出形材（２０ｂ、２０ｃ、２０ｄ、２０ｅ、２０ｆ）においては、Ｘ方向における端部側は切欠き部６０の部分となっている。 As shown in FIG. 3, when the extending portion 23 is formed as a part of the hollow extruded shape 20a, a hollow extruded shape other than the hollow extruded shape 20a is provided below the hollow extruded shape 20a. (20b, 20c, 20d, 20e, 20f) are connected side by side in the Z direction. In this case, the dimension in the X direction of these hollow extruded shapes (20b, 20c, 20d, 20e, 20f) is smaller than the dimension in the longitudinal direction of the side structure 20 by the dimension in the X direction of the end side structure 24. Is set. That is, in the hollow extruded shapes (20b, 20c, 20d, 20e, 20f) other than the hollow extruded shape 20a, the end portion side in the X direction is a portion of the notch 60.
（端部側構体）

The reinforcing material 29 is a reinforcing material for connecting the vertical edge material 26, the horizontal edge material 28, and the face plate 25, and a plurality of reinforcing materials 29 are provided. The vertical edge member 26, the horizontal edge member 28, and the reinforcing member 29 are all formed of an extruded shape made of an aluminum alloy.
　図４の断面図で示されるように、中央部側構体２２は、中空押出形材であり、対向する車内側面板２２ａと車外側面板２２ｂの２枚の面板とこれら面板を接続するリブから形成される。そして端部側構体２４の縦縁材２６は、本体部２６ａと、重ね部２７と、面板接続部２６ｂを備えている。縦縁材２６の本体部２６ａは、上側から見て中空の四角柱状の形状であり、Ｚ方向に沿って形成されている。重ね部２７は、本体部２６ａより、Ｘ方向が中央側の端部から、Ｙ方向が車内側の端部から、側構体２０の中央部側へ向けてＸ方向に延びている板状部材である。そして、重ね部２７は縦縁材２６と一体に形成されている。また、面板接続部２６ｂは、本体部２６ａからＸ方向外側（側構体２０の端部側）へ突出する突起状の板部材であり、面板２５の車内側に重ねて接続することができる。このとき、面板接続部２６ｂを、面板２５の厚み分だけ車内側に位置させる。これにより、面板２５の車外側の表面と縦縁材２６の本体部２６ａの車外側の表面のＹ方向の位置を合わせることができ、なめらかな車外側の表面として外観がよいものとすることができる。 As shown in the cross-sectional view of FIG. 4, the central portion side structure 22 is a hollow extruded shape member, and is formed of two face plates, an in-vehicle side surface plate 22a and an in-vehicle side surface plate 22b, and ribs connecting these face plates. Is done. And the vertical edge material 26 of the edge part side structure 24 is provided with the main-body part 26a, the overlap part 27, and the faceplate connection part 26b. The main body portion 26a of the vertical edge member 26 has a hollow quadrangular prism shape when viewed from above, and is formed along the Z direction. The overlapping portion 27 is a plate-like member extending from the main body portion 26a in the X direction in the X direction from the end portion on the center side, and in the Y direction from the end portion on the vehicle inner side toward the center portion side of the side structure 20. is there. The overlapping portion 27 is formed integrally with the vertical edge member 26. The face plate connecting portion 26 b is a protruding plate member that protrudes from the main body portion 26 a to the outside in the X direction (the end portion side of the side structure 20), and can be overlapped and connected to the inside of the face plate 25. At this time, the face plate connecting portion 26b is positioned inside the vehicle by the thickness of the face plate 25. Thereby, the position in the Y direction of the vehicle outer surface of the face plate 25 and the vehicle outer surface of the main body portion 26a of the vertical edge member 26 can be matched, and the appearance as a smooth vehicle outer surface is good. it can.
　また、図４に示されるように、重ね部２７の車外側の面は、中央部側構体２２と略平行な面を有している。これにより、端部側構体２４の車外側の面の位置と中央部側構体２２の車外側の面の位置、つまり中心線７０からＹ方向への距離を整合させることができる。この重ね部２７の車外側の面を中央部側構体２２の車内側の面板に当接して重ねることで端部側構体２４のＹ方向の面位置を容易に決めることができる。そして、端部側構体２４の重ね部２７と中央部側構体２２を接続することができる。さらに、中央部側構体２２におけるＸ方向の端部側の側面は、縦縁材２６の本体部２６ａのＸ方向の側面に当接させる。このことにより、中央部側構体２２及び端部側構体２４のＸ方向の位置を容易に決めることができる。そして、端部側構体２４の縦縁材２６と中央部側構体２２を接続することができる。このとき縦縁材２６の本体部２６ａの車外側の面と中央部側構体２２の車外側の面はＹ方向で同じ位置になることで、滑らかな車外側の表面にできる。 Further, as shown in FIG. 4, the surface on the vehicle exterior side of the overlapping portion 27 has a surface substantially parallel to the center side structure 22. As a result, the position of the outer surface of the end side structure 24 and the position of the outer surface of the center side structure 22, that is, the distance from the center line 70 in the Y direction can be matched. The surface of the end portion side structure 24 in the Y direction can be easily determined by abutting and overlapping the surface on the vehicle outer side of the overlapping portion 27 with the face plate on the vehicle inner side of the central portion side structure 22. Then, the overlapping portion 27 of the end portion side structure 24 and the central portion side structure 22 can be connected. Further, the side surface on the end portion side in the X direction in the center side structure 22 is brought into contact with the side surface in the X direction of the main body portion 26 a of the vertical edge member 26.

（側構体の製造方法の説明）
　次に、中央部側構体２２と端部側構体２４を接続して側構体２０を製造する製造過程を説明する。 (Description of manufacturing method of side structure)
Next, a manufacturing process for manufacturing the side structure 20 by connecting the center-side structure 22 and the end-side structure 24 will be described.
　中央部側構体２２と端部側構体２４を接続するためには、定盤の上に中央部側構体２２を置いて、端部側構体２４を位置決めしていく。まず、中央部側構体２２のＸ方向の端部において端部側構体２４を位置決めする。この時、図４で示されるように中央部側構体２２のＸ方向の端部では、中央部側構体２２の車内側面板２２ａが、端部側構体２４の重ね部２７に重ねられる。これにより、端部側構体２４の中央部側構体２２に対するＹ方向の位置決めを短時間で済ませることができる。さらに、図４で示されるように中央部側構体２２のＸ方向の端部は、端部側構体２４の縦縁材２６の本体部２６ａに当接してＸ方向の位置決めも短時間で済ませることができる。 In order to connect the center part side structure 22 and the end part side structure 24, the center part side structure 22 is placed on the surface plate, and the end part side structure 24 is positioned. First, the end side structure 24 is positioned at the end of the center side structure 22 in the X direction. At this time, as shown in FIG. 4, at the end portion in the X direction of the central portion side structure 22, the vehicle interior side surface plate 22 a of the central portion side structure 22 is overlapped with the overlapping portion 27 of the end portion side structure 24. Thereby, the positioning of the end part side structure 24 with respect to the center part side structure 22 in the Y direction can be completed in a short time. Furthermore, as shown in FIG. 4, the end portion in the X direction of the central portion side structure 22 abuts on the main body portion 26 a of the vertical edge member 26 of the end portion side structure 24, and positioning in the X direction can be completed in a short time. Can do.
　次に、端部側構体２４をＺ方向（上方向）にスライド（移動）させる。この時、図４で示されるように中央部側構体２２のＸ方向の端部は、端部側構体２４の縦縁材２６の本体部２６ａに当接している状態となっており、この状態のままスライドさせる。これにより、端部側構体２４のＸ方向の位置が一定のままＺ方向に端部側構体２４を移動させることができる。すなわち、縦縁材２６の本体部２６ａは、Ｘ方向の位置を一定とするためのガイド部材として機能する。さらに、図４で示されるように中央部側構体２２のＸ方向の端部では、中央部側構体２２の車内側面板２２ａが、端部側構体２４の重ね部２７に重ねた状態になっており、この状態のままスライドさせる。これにより、端部側構体２４のＹ方向の位置が一定のままＺ方向に端部側構体２４を移動させることができる。すなわち、重ね部２７は、Ｙ方向の位置を一定とするためのガイド部材として機能する。このように、横縁材２８の本体部２８ａと重ね部２７によりガイドされながら、端部側構体２４がＺ方向にスライドさせることができる。 Next, the end side structure 24 is slid (moved) in the Z direction (upward). At this time, as shown in FIG. 4, the end portion in the X direction of the central portion side structure 22 is in contact with the main body portion 26 a of the vertical edge member 26 of the end portion side structure 24. Slide it. Thereby, the end part structure 24 can be moved in the Z direction while the position of the end part structure 24 in the X direction is constant. That is, the main body portion 26a of the vertical edge member 26 functions as a guide member for keeping the position in the X direction constant. Further, as shown in FIG. 4, at the end portion in the X direction of the central portion side structure 22, the vehicle interior side surface plate 22 a of the central portion side structure 22 is overlaid on the overlapping portion 27 of the end portion side structure 24. And slide in this state. Thereby, the end part structure 24 can be moved in the Z direction while the position of the end part structure 24 in the Y direction is constant. That is, the overlapping portion 27 functions as a guide member for making the position in the Y direction constant. As described above, the end-side structure 24 can be slid in the Z direction while being guided by the main body portion 28 a of the lateral edge member 28 and the overlapping portion 27.
　そして、端部側構体２４を横縁材２８が延伸部２３に当接するまでスライドすることで、端部側構体２４の位置決めをすることができる。図５は、端部側構体２４の横縁材２８が延伸部２３に当接して接続した状態を示している。端部側構体２４の横縁材２８の当接部に、延伸部２３の車内側面板２３ａと車外側面板２３ｂの少なくとも一方の面板が当接する。横縁材２８の当接部としては、上述したように、本体部２８ａ、車内側接続部２８ｂ、車外側接続部２８ｃのうち少なくとも１以上が当接部となり得る。これにより、Ｚ方向位置が決定される。このとき、横縁材２８の車内側接続部２８ｂは、延伸部２３の車内側面板２３ａと重なるように配置されていると共に、横縁材２８の車外側接続部２８ｃは、延伸部２３の車外側面板２３ｂと重なるように配置されている。 Then, the end side structure 24 can be positioned by sliding the end side structure 24 until the lateral edge member 28 comes into contact with the extending portion 23. FIG. 5 shows a state in which the lateral edge member 28 of the end side structure 24 is in contact with and connected to the extending portion 23. At least one face plate of the inboard side surface plate 23a and the outboard side surface plate 23b of the extending portion 23 abuts on the abutting portion of the lateral edge member 28 of the end side structure 24. As described above, at least one or more of the main body portion 28a, the vehicle interior connection portion 28b, and the vehicle exterior connection portion 28c can serve as the contact portion of the lateral edge member 28. Thereby, the Z direction position is determined. At this time, the vehicle inner side connection portion 28b of the lateral edge member 28 is arranged so as to overlap the vehicle interior side surface plate 23a of the extending portion 23, and the vehicle outer side connection portion 28c of the lateral edge member 28 is connected to the vehicle of the extending portion 23. It arrange | positions so that it may overlap with the outer surface board 23b.
　端部側構体２４の位置決めが完了した後、端部側構体２４と中央部側構体２２を接合する。まず、図４に示される端部側構体２４の縦縁材２６と中央部側構体２２のＸ方向との突き合わせ部を接合する。それとともに、縦縁材２６の重ね部２７と中央部側構体２２の車内側面板２２ａと接合する。さらに、図５に示される端部側構体２４の横縁材２８と、中央部側構体２２の延伸部２３（中空押出形材２０ａ）の当接部を接合する。ここでの接合は、例えば、横縁材２８の車内側接続部２８ｂと延伸部２３の車内側面板２３ａ、横縁材２８の車外側接続部２８ｃと延伸部２３の車外側面板２３ｂを接合すること等により行われる。このようにして、縦縁材２６および横縁材２８と中央部側構体２２との接合が完了すると、中央部側構体２２に対して端部側構体２４が接続され、側構体２０が完成する。 After the positioning of the end side structure 24 is completed, the end side structure 24 and the center side structure 22 are joined. First, the butted portion between the vertical edge member 26 of the end side structure 24 and the X direction of the center side structure 22 shown in FIG. 4 is joined. At the same time, the overlapping portion 27 of the vertical edge member 26 and the vehicle interior side surface plate 22 a of the central portion side structure 22 are joined. Further, the lateral edge member 28 of the end side structure 24 shown in FIG. 5 and the contact portion of the extending portion 23 (hollow extruded shape member 20a) of the center side structure 22 are joined. The joining here is, for example, joining the vehicle interior side connection portion 28b of the lateral edge member 28 and the vehicle interior side surface plate 23a of the extending portion 23, and the vehicle exterior side connection portion 28c of the lateral edge member 28 and the vehicle exterior side surface plate 23b of the extended portion 23. It is done by things. In this way, when the joining of the vertical edge member 26 and the horizontal edge member 28 to the central portion side structure 22 is completed, the end portion side structure 24 is connected to the central portion side structure 22, and the side structure 20 is completed. .
　このように、端部側構体２４における縦縁材２６に重ね部２７を備えることに加えて、中央部側構体２２のＸ方向の端部の上端部に延伸部２３を備えることにより、中央部側構体２２に対して端部側構体２４を容易に位置決めすることができる。このため、側構体２０の製作工数を小さくすることができると共に、確実な製作が可能となる。 Thus, in addition to providing the vertical edge member 26 in the end portion side structure 24 with the overlapping portion 27, the center portion side structure 22 is provided with the extending portion 23 at the upper end of the end portion in the X direction. The end side structure 24 can be easily positioned with respect to the side structure 22. For this reason, the manufacturing man-hour of the side structure 20 can be reduced, and reliable manufacturing becomes possible.
