The bogie comprises two oppositely-arranged side frames, a swing bolster and a wheel set assembly are installed between the two side frames, a lower center plate is installed on the swing bolster, each side frame comprises an upper cover plate, a supporting plate and a lower cover plate, the upper cover plates and the lower cover plates are oppositely arranged up and down, the supporting plates are arranged between the upper cover plates and the lower cover plates, and the supporting plates are arranged between the upper cover plates and the lower cover plates. The upper cover plate, the lower cover plate and the supporting plate are fixedly connected through bolts, rectangular spaces are formed in the middle positions of the side frames, the two side frames are fixedly connected through a spring assembly, and the two ends of the spring assembly are fixedly installed in the rectangular spaces of the corresponding side frames through bolts. The two ends of the swing bolster are inserted into the rectangular space and supported by the bearing springs composed of the springs, the side frames are formed by connecting plates through bolts, casting and welding processes are avoided, the possibility of defect occurrence is reduced, the manufacturing efficiency is improved, the two side frames are connected into a whole through the spring assembly, and the manufacturing cost is reduced. Rhombic deformation of the side frame in the operation process is effectively limited, and the operation quality and speed are improved.
一种转向架及铁路货车,包括两个相对设置的侧架,两个侧架之间安装有摇枕和轮对组成,摇枕上安装有下心盘,侧架包括上盖板、支撑板和下盖板,上盖板与下盖板上下相对设置,支撑板设置在上盖板和下盖板之间,上盖板、下盖板和支撑板之间通过螺栓固定连接,侧架的中间位置处含有矩形空间,两个侧架之间通过弹簧组成固定连接,弹簧组成的两端通过螺栓固定安装在对应侧架的矩形空间内,摇枕的两端插装在矩形空间内并通过弹簧组成的承载弹簧支撑,侧架采用板材螺栓连接而成,避免了铸造和焊接工艺,降低了缺陷发生的可能性,提高了制造效率,弹簧组成将两个侧架连接为一个整体,有效限制了运行过程中侧架的菱形变形,提高运行品质及速度。
