The invention relates to the technical field of railway vehicles, and provides a side door frame, a side wall assembly and a railway vehicle, the side door frame comprises a door upper cross beam, a lower doorsill, a connecting piece and a pair of door stand columns, the pair of door stand columns are parallel and distributed at intervals in the reference direction, and the door stand columns are fixedly connected with a side wall plate; the two ends of the door upper cross beam are correspondingly connected with the upper ends of the pair of door stand columns, and the door upper cross beam is fixedly connected with the side wall upper edge beam. The lower ends of the pair of door stand columns are fixedly connected with a lower doorsill, and the lower doorsill is fixedly connected with a side wall lower edge beam. The connecting pieces are arranged on the sides, away from each other, of the pair of door stand columns, and the connecting pieces are arranged at the upper end and the lower end of each door stand column and suitable for being fixedly connected with side wall stand columns. Therefore, the side door frame is of an independent and integral structure, is formed before the side wall assembly and the underframe assembly, is less affected by assembly errors and tolerance accumulation, can be independently adjusted and repaired, and can be beneficial to improving the structural size precision of a door area mounting interface.

    本发明涉及轨道车辆技术领域,提供一种侧门门框、侧墙总成及轨道车辆,其中,侧门门框包括门上横梁、下门槛、连接件和一对门立柱,一对门立柱平行且沿参考方向间隔分布,门立柱与侧墙墙板固定连接;门上横梁的两端与一对门立柱的上端对应连接,门上横梁与侧墙上边梁固定连接;一对门立柱的下端均与下门槛固定连接,下门槛与侧墙下边梁固定连接;连接件设于一对门立柱相互远离的一侧,每个门立柱的上下两端均设有连接件,连接件适于侧墙立柱固定连接。如此,侧门门框为独立的、整体的结构,形成于侧墙总装和底架总装之前,受装配误差、公差积累的影响较小,且可以单独调修,可以有利于提高门区安装接口的结构尺寸精度。
