A hinged framework for a subway bogie with a built-in axle box is of a split structure formed by mixing and welding low alloy steel plates and steel castings, the low alloy steel plates and the steel castings are assembled together through a hinged structure in an opposite insertion mode, and the hinged framework comprises a cross beam unit, a first side beam unit, a second side beam unit and the hinged structure. The hinged framework for the subway bogie with the built-in axle boxes has the advantages of being compact in structure, light in weight and the like, especially under the working conditions of small curves and poor line conditions, the trafficability of the bogie is high, curve ultrahigh change passing and track irregularity can be achieved through framework hinged displacement adaptation, and the bogie is high in practicability. Especially under the working conditions of many small-radius curves of existing lines and poor line conditions, the bogie is high in trafficability and reasonable in wheel load distribution, the wheel load of the vehicle can be adjusted through a hinge structure and self-dynamic distribution, and wheel load balance is achieved.

    一种用于轴箱内置式地铁转向架的铰接构架,所述的构架采用低合金钢板和铸钢件混合焊接的分体式结构,通过对插的方式使用铰接结构组装到一起,包括横梁单元、第一侧梁单元、第二侧梁单元和铰接结构;用于轴箱内置式地铁转向架的铰接构架具有结构紧凑,重量轻等特点,尤其是小曲线和线路条件差的工况下,转向架的通过能力强,可以通过构架铰接变位适应实现曲线超高变化通过和适应轨道不平顺,尤其是既有线小半径曲线较多和线路条件较差的工况下,转向架的通过能力较强,轮重分配合理,能够通过铰接结构,自身动分配调整车辆轮重,实现轮重均衡。
