The invention discloses a chassis and side wall connecting structure, a vehicle body and a railway vehicle, the chassis and side wall connecting structure comprises a chassis and a side wall, the chassis comprises a floor and a side beam, the first side of the side beam is provided with a supporting part, the supporting part is used for supporting the floor, and the floor is connected with the side beam through a first connecting piece; the side wall comprises an inner plate and an outer plate, the inner plate is located above the edge beam and connected with the edge beam or the floor, the outer plate extends to the second side of the edge beam and connected with the edge beam through a second connecting piece, and the second side is the side, away from the floor, of the edge beam. By extending the outer plate of the side wall to the side part of the side beam, the contact area between the outer plate and the side beam can be increased, in addition, the inner plate of the side wall is connected with the side beam or the floor, the connection strength of the side wall can be enhanced, and in addition, the side wall can be positioned in the horizontal direction through the contact between the outer plate and the side beam; in addition, the supporting parts are arranged on the edge beams to support the floor, the floor can be positioned in the vertical direction, and therefore the side wall and the bottom frame can be conveniently installed.

    本发明公开了一种底架与侧墙的连接结构、车体及轨道车辆,包括底架和侧墙,其中底架包括地板和边梁,边梁的第一侧设有支撑部,支撑部用于支撑地板,地板通过第一连接件与边梁连接;侧墙包括内板和外板,内板位于边梁的上方,且与边梁或者地板连接,其中外板延伸至边梁的第二侧,且与边梁通过第二连接件连接,第二侧为边梁远离地板的一侧。通过将侧墙的外板延伸至边梁的侧部,能够提高两者的接触面积,此外侧墙的内板与边梁或者地板连接,能够加强侧墙的连接强度,另外通过外板和边梁的接触,可以对侧墙起到水平方向的定位作用,此外通过在边梁上设置支撑部来支撑地板,能够对地板起到竖直方向的定位作用,因此可以便于侧墙和底架的安装。
