The invention discloses a railway flatcar concave underframe and a railway flatcar. The depressed center frame of the railway flatcar comprises two side beams, a cross beam frame, a first end beam, a second end beam, a traction beam and a sleeper beam. The two side beams are symmetrically arranged; the side beams are of a sash structure. The outer contour of each side beam comprises a downward concave part and a bent part in the length direction of the side beam. The bending part and the concave part are arranged to enable the side beam to have a gradually-changed bending angle type middle concave structure; the cross beam sash is arranged between the lower concave parts of the two side beams and is vertically connected with the two side beams; the first end beam and the second end beam are symmetrically arranged; the two ends of the first end beam are perpendicularly connected with one ends of the two side beams respectively, and the two ends of the second end beam are perpendicularly connected with the other ends of the two side beams respectively. The sleeper beam and the traction beam are both of a double-web box type structure. The rigidity and strength of the concave underframe can be further improved, and the height of a bearing surface is reduced.

    本发明公开了一种铁路平车凹底架及铁路平车。该铁路平车凹底架包括两根侧梁、横梁框格、第一端梁、第二端梁、牵引梁和枕梁;两根侧梁对称设置;侧梁为框格结构;侧梁的外轮廓沿其长度方向包括下凹部和折弯部;折弯部和下凹部设置为能够使得侧梁具有渐变折角式中部下凹结构;横梁框格设置于两根侧梁的下凹部之间,并与两根侧梁垂直相连;第一端梁和第二端梁对称设置;第一端梁的两端分别与两根侧梁的一端垂直相连,第二端梁的两端分别与两根侧梁的另一端垂直相连;枕梁和牵引梁均为双腹板箱型结构。本发明的凹底架可以进一步提高其刚强度,降低承载面高度。
