The invention discloses a rail transit vehicle chassis structure and a machining method of the rail transit vehicle chassis structure. The rail transit vehicle chassis structure comprises a sleeper beam, a traction beam, a floor, an edge beam and an end beam. The end beam middle section and the sleeper beam middle section are welded to the floor through the traction beam, and the end beam edge and the sleeper beam edge are connected through welding of the two sets of edge beams. A welding seam between the traction beam and the sleeper beam is a single V-shaped welding seam. A reinforcing rib is arranged on the traction beam, and a welding seam between the reinforcing rib and the sleeper beam is a Z-direction welding seam. A torsion bar seat installation face is arranged at the welding position of the sleeper beam and the edge beam, and the number of the torsion bar rivet pulling holes in the torsion bar seat installation face is 12.

    本发明公开了一种轨道交通车辆底架结构及一种轨道交通车辆底架结构的加工方法,包括枕梁、牵引梁、地板、边梁及端梁;所述端梁中段与枕梁中段通过牵引梁焊接在地板上,所述端梁边缘及枕梁边缘通过两组边梁焊接完成连接;所述牵引梁与枕梁之间的焊缝为单V焊缝。所述牵引梁上设置有加强筋,所述加强筋与枕梁之间的焊缝为Z向焊缝。所述枕梁与边梁焊接处设置有扭杆座安装面,所述扭杆座安装面上的扭杆拉铆孔为12个。
