Title
(EN) END CHASSIS STRUCTURE FOR USE IN RAILWAY VEHICLE AND RAILWAY VEHICLE
(FR) STRUCTURE DE CHÂSSIS D'EXTRÉMITÉ POUR UTILISATION DANS UN VÉHICULE FERROVIAIRE ET VÉHICULE FERROVIAIRE

Abstract
(EN)
An end chassis structure for use in a railway vehicle, comprising a traction beam (1) and a pair of upper support plates (4) respectively mounted on two sides of the traction beam (1) and a pair of lower support plates (5) arranged opposite to one another underneath the upper support plates (4), the side edges of the upper support plates (4) and the lower support plates (5) being fixedly connected to the side walls of the traction beam (1), the upper surface of the upper support plates (4) forming an upper support surface used for supporting a floor plate, and the lower surface of the lower support plates (5) forming a lower mounting face of a component interface. The structure of the upper support plates (4) and the lower support plates (5) replaces the previous cross beam structure for supporting a floor plate, increasing the support area, improving the bearing capacity, preventing the deformation caused by local stress concentration, and increasing overall strength and rigidity; the arrangement of the lower support plates (5) increases the interface area of the lower part of the chassis and increases the component mounting area, the position of the components being more rational and simple. Also comprising a railway vehicle provided with the end chassis structure.
(FR)
L'invention concerne une structure de châssis d'extrémité destinée à être utilisée dans un véhicule ferroviaire, comprenant une poutre de traction (1), une paire de plaques de support supérieures (4) respectivement montées sur deux côtés de la poutre de traction (1) et une paire de plaques de support inférieures (5) disposées à l'opposé l'une de l'autre sous les plaques de support supérieures (4). Les bords latéraux des plaques de support supérieures (4) et des plaques de support inférieures (5) sont reliés à demeure aux parois latérales de la poutre de traction (1), la surface supérieure des plaques de support supérieures (4) forme une surface de support supérieure utilisée pour supporter une plaque de plancher, et la surface inférieure des plaques de support inférieures (5) forment une face de montage inférieure d'une interface de composant. La structure des plaques de support supérieures (4) et des plaques de support inférieures (5) remplace la structure de poutre transversale précédente servant à supporter une plaque de plancher, augmentant la zone de support, améliorant la capacité de support, empêchant la déformation provoquée par la concentration de contrainte locale, et augmentant la résistance et la rigidité globales. L'agencement des plaques de support inférieures (5) augmente la zone d'interface de la partie inférieure du châssis et augmente la zone de montage de composants, la position des composants étant plus rationnelle et simple. L'invention concerne également un véhicule ferroviaire équipé de la structure de châssis d'extrémité.

一种轨道车辆用端部底架结构,包括牵引梁(1)以及分别安装在牵引梁(1)两侧的一对上支撑板(4)和相对设置在一对上支撑板(4)下方的一对下支撑板(5),上支撑板(4)和下支撑板(5)的侧边均与牵引梁(1)的侧壁固定连接,上支撑板(4)的上表面形成用于支撑地板的上支撑面,下支撑板(5)的下表面形成零部件接口的下安装面。由上支撑板(4)和下支撑板(5)的结构代替之前的横梁结构来支撑地板,使支撑面积增加,承载能力提高,避免局部应力集中带来的变形,增加了整体的强度、刚度;下支撑板(5)的设置增加了底架下部的接口面积,零部件安装面积增加,零部件的位置布置更加合理简便。还包括一种具有所述端部底架结构的轨道车辆。
