本发明属于轨道交通技术领域,尤其涉及一种转向架。该转向架包括构架、摇枕以及中央悬吊装置,其中构架包括上弦梁、下弦梁以及连接梁,所述上弦梁以及所述下弦梁相对设置,所述上弦梁以及所述下弦梁之间通过多个间隔设置的所述连接梁连接,摇枕通过所述中央悬吊装置悬挂在所述下弦梁的中部。本发明可减小轨道梁和支撑轨道梁的墩柱结构尺寸,以降低用钢量,达到降低线路建设成本的目的。

    The invention belongs to the technical field of rail transit, and particularly relates to a bogie. The bogie comprises a framework, a swing bolster and a central suspension device, the framework comprises an upper chord beam, a lower chord beam and connecting beams, the upper chord beam and the lower chord beam are oppositely arranged, and the upper chord beam and the lower chord beam are connected through the multiple connecting beams arranged at intervals. And the swing bolster is suspended in the middle of the lower chord beam through the central suspension device. The sizes of pier columnstructures of the track beam and the supporting track beam can be reduced, so that the steel consumption is reduced, and the purpose of reducing the line construction cost is achieved.
