The invention relates to the technical field of bulldozers, in particular to a bogie frame structure of a bulldozer, which solves the problem that the manufacturing precision of a bogie frame is difficult to guarantee, and comprises a front section assembly, a middle section assembly, a pivot box assembly, a bottom plate, a balance beam seat and a trunnion, wherein the bottom plate is connected with the front section assembly, the middle section assembly and the pivot box assembly in a welding manner; the balance beam base is arranged on one side of the middle section assembly in a welded mode, and the trunnion is arranged on one side of the middle section assembly in a welded mode. The manufacturing precision of the trolley frame is improved by one grade; CAE analysis shows that the strength is increased by 30%; the weight is reduced by 10%; the total assembling and welding efficiency of the bogie frame is improved, and the working hours are reduced by 30%; and comprehensive cost reduction by 15%.

    一种推土机的台车架结构,涉及推土机技术领域,解决了台车架制造精度较难保证的问题,包括前段合件、中段合件、枢轴箱合件、底板、平衡梁座和耳轴,所述的底板通过焊接的方式分别与前段合件、中段合件、枢轴箱合件相连接,所述的平衡梁座通过焊接的方式设置在中段合件的一侧,所述的耳轴通过焊接的方式设置在中段合件的一侧;台车架制造精度上升一个等级;经CAE分析强度增加30%;重量下降10%;台车架总装配焊效率提升,工时降低30%;综合成本降低15%。
