Description

本発明の鉄道車両の構体構造は、車体の車幅方向両端部に夫々位置する側外板と、前記車体の車両長手方向前端部に位置し、車幅方向両端部が前記側外板に接合されている妻構体と、を備え、前記妻構体は、車幅方向端部において、前記側外板に向かって車両長手方向後方に傾斜している傾斜部と、前記傾斜部の長手方向前方側にある傾斜面に形成され、前記傾斜部より摩擦抵抗が小さい固体潤滑部とを有する構体構造を備えたものである。 Assembly structure of a railway vehicle according to the present invention, the side skins respectively located in the vehicle width direction end portions of the vehicle body, located in the vehicle longitudinal direction front end portion of the vehicle body, the vehicle width direction end portions on the side outer plate A wife structure that is joined, and the wife structure has an inclined part that is inclined rearward in the longitudinal direction of the vehicle toward the side outer plate at an end in the vehicle width direction, and a front side in the longitudinal direction of the inclined part. And a solid structure having a solid lubricating part having a lower frictional resistance than that of the inclined part.

＜妻構体＞
妻構体３は、図１に示すように、妻外板７、貫通路柱８、かもい９、桟部材１０、アーチ桁２３及び隅柱５を有している。図１に示すように妻外板７は、正面視で大略的に逆Ｕ字状の板部材であり、台枠２に立設されている。妻外板７の上端は、後述するアーチ桁２３まで延在しており、妻外板７は、逆Ｕ字状の切欠きが形成され、中央部分に貫通路７ａを有している。貫通路７ａの両側には、貫通路７ａに沿って貫通路柱８が夫々立設されており、貫通路７ａの上側には、かもい９が設けられている。貫通路柱８は、台枠２からアーチ桁２３まで延在しており、かもい９は、これら２つの貫通路柱８の間を渡すように左右に延在している。また、妻外板７の内側には、貫通路柱８より外側に断面ハット状の複数の桟部材１０が上下左右に夫々延在させて設けられている。 <Wife structure>
As shown in FIG. 1 , the wife structure 3 has a wife outer plate 7, a through-pass column 8, a frame 9, a crosspiece member 10, an arch girder 23, and a corner column 5. As shown in FIG. 1, the wife outer plate 7 is a substantially U-shaped plate member in a front view and is erected on the frame 2. The upper end of the end face plate 7 extends to an arch girder 23, which will be described later, and the end end face plate 7 is formed with an inverted U-shaped notch and has a through passage 7a at the center. On both sides of the through-passage 7a, through-passage pillars 8 are erected along the through-passage 7a, respectively, and a gill 9 is provided on the upper side of the through-passage 7a. The through-pass column 8 extends from the underframe 2 to the arch girder 23, and the cam 9 extends to the left and right so as to pass between the two through-pass columns 8. In addition, a plurality of crosspiece members 10 having a hat-shaped cross section are provided on the inner side of the end plate 7 so as to extend from the through-pass column 8 to the upper, lower, left, and right sides, respectively.
