The invention relates to the technical field of railway vehicles, in particular to a side wall unit, a vehicle body and a railway vehicle. The side wall unit comprises side wall framework, the side wall framework is used for being connected between adjacent vehicle doors through an upper edge beam and a lower edge beam. The side wall framework comprises a pair of main stand columns connected between the upper edge beam and the lower edge beam in a spaced mode, a pair of window side stand columns arranged between the pair of main stand columns at intervals, a pair of main cross beams respectively perpendicular to and connected with the pair of window side stand columns in a crossed manner, and a plurality of oblique beams. One end of each oblique beam is fixedly connected to one main standcolumn, the other end of each oblique beam is connected with the upper edge beam or the lower edge beam, and the oblique beams are connected to the connecting positions of the main cross beams and thewindow edge stand columns in a crossed mode. The structural strength of the side wall framework can be effectively improved, so that the side wall unit can meet the vehicle body bearing requirement and the flatness requirement; and the weight of the side wall framework can be effectively reduced, so that the side wall unit meets the vehicle body light weight requirement.

    本发明涉及轨道车辆技术领域,尤其涉及侧墙单元、车体及轨道车辆。该侧墙单元包括侧墙骨架,侧墙骨架用于通过上边梁和下边梁连接在相邻的车门之间,侧墙骨架包括:一对主立柱,成间隔的连接于上边梁和下边梁之间;一对窗边立柱,成间隔的设置在一对主立柱之间;一对主横梁,分别与一对窗边立柱相互垂直且交叉连接;若干个斜梁,各个斜梁的一端分别固定连接在主立柱上,各个斜梁的另一端分别与上边梁或下边梁连接,且各个斜梁分别交叉连接在主横梁与窗边立柱的连接处。本发明能有效提高侧墙骨架的结构强度,以使侧墙单元能满足车体承载要求及平面度要求,在此基础上,还能有效减轻侧墙骨架的重量,从而使侧墙单元满足车体轻量化要求。
