The invention discloses a railway flatcar body and a longitudinal beam of a railway flatcar, the longitudinal beam comprises a first sub-beam and a second sub-beam, the second sub-beam is located below the first sub-beam and located in the middle area of the first sub-beam in the longitudinal direction, and the second sub-beam is connected with the first sub-beam through a connecting piece. The longitudinal beam comprises the first sub-beam and the second sub-beam which are split, the first sub-beam and the second sub-beam are connected through the connecting piece, welding is less, the green production level is high, reasonable distribution of strength at different areas of the longitudinal beam is facilitated, and then the weight can be reduced.
本发明公开一种铁路平车的车体及铁路平车的纵梁,其中,该纵梁包括第一分梁和第二分梁,所述第二分梁位于所述第一分梁的下方,并位于所述第一分梁在纵向上的中间区域,且所述第二分梁通过连接件和所述第一分梁相连。上述纵梁包括分体式的第一分梁和第二分梁,第一分梁和第二分梁之间采用连接件连接,焊接较少,绿色化生产水平较高,且有利于纵梁不同区域处强度的合理分配,进而可以减轻重量。
