The invention relates to a railway vehicle, a vehicle end hinging structure thereof and a vehicle end hinging mounting structure. The vehicle end hinge installation structure comprises a structure body. Boundary beam mounting seats are respectively arranged at two ends of the structure main body; the boundary beam mounting seat is detachably connected with a vehicle body chassis boundary beam; and a hinge device mounting seat is arranged on the front side surface of the structure main body. The hinge device mounting seat is used for being detachably connected with a hinge device, and a floor connecting seat is arranged on the rear side surface of the structure body and used for being detachably connected with a vehicle body chassis floor. According to the rail vehicle end hinge mounting structure, the side beam mounting base and the floor connecting base are detachably connected with the bottom plate of the vehicle body chassis and the two side beams correspondingly, and maintenance and replacement are convenient; the structure can disperse the borne stress to the vehicle body boundary beam and floor area, so that the stress of the vehicle body chassis is uniform, and the bearing of the chassis is dispersed. Therefore, the fatigue damage is not prone to occurring at the joint of the vehicle body chassis and the railway vehicle end hinged installation structure.
本发明涉及一种轨道车辆及其车端铰接结构与车端铰接安装结构,该车端铰接安装结构包括结构主体,结构主体的两端分别设置有边梁安装座,边梁安装座用于与车体底架边梁可拆卸连接,结构主体的前侧表面设置有铰接装置安装座,铰接装置安装座用于与铰接装置可拆卸连接,结构主体的后侧表面设置有地板连接座,地板连接座用于与车体底架地板可拆卸连接;上述轨道车辆车端铰接安装结构通过边梁安装座以及地板连接座分别与车体底架的底板以及两个边梁可拆卸连接,便于维修及更换,并能够将所承受的应力分散至车体边梁及地板区域,使车体底架受力均匀,分散底架承载,使车体底架与轨道车辆车端铰接安装结构的连接处不易出现疲劳损伤。
