The invention discloses a bottom side beam of a carriage, a connecting structure of a side plate and a bottom frame and the carriage, the bottom side beam of the carriage comprises a web plate, a wing plate extending from the inner surface of the web plate to the inner side and a supporting plate extending downwards from the inner side edge of the wing plate, the upper surface of the wing plate is supported on the side plate, and the lower surface of the wing plate is supported on the bottom frame. A pressing plate which horizontally extends inwards and is arranged on the bottom frame in a pressing mode is arranged at the lower end of the supporting plate. The installation height of the carriage side plates and the bottom side beams is increased, under the condition that the height positions of the top ends of the carriage side plates are not changed, the side plates have the relatively small overall height, when the carriage side plates are transported in a fragmented mode, the side plates with the relatively small height occupy small space, and the logistics transportation cost is reduced.

    本发明公开了一种车厢的底侧梁、侧板与底架的连接结构及车厢,车厢的底侧梁,包括腹板、由腹板的内表面向着内侧延伸的翼板、由翼板的内侧边向下延伸的支撑板,翼板的上表面支撑于侧板上,支撑板的下端部设置有水平向内延伸并压设于底架上的压板。本发明抬高了车厢侧板与底侧梁的安装高度,在车厢侧板顶端高度位置不变的情况下,使侧板具有相对较小的整体高度,在车厢侧板分片运输时,高度相对较小的侧板占用空间小,降低了物流运输的成本。
