The invention relates to the technical field of freight frames, and provides a truss type highway-railway dual-purpose freight frame which comprises three-dimensional trusses, a highway walking system suspension and a traction frame, the three-dimensional trusses comprise two middle plane trusses, two side plane trusses and a plurality of transverse connecting beams, and the side plane trusses and the middle plane trusses are arranged in parallel. The middle plane truss is connected through the transverse connecting beam, the two side plane trusses are connected to the two sides of the middle plane truss respectively, a plurality of arc-shaped grooves are formed in the bottoms of the two side plane trusses, the side plane trusses are further provided with fixing parts, and the fixing parts are used for fixing a railway walking system. By means of the technical scheme, the weight of a freight frame in the prior art is reduced, and highway and railway dual purposes can be achieved.
本发明涉及货运车架技术领域,提出了一种桁架式公铁两用货运车架,包括三维桁架、公路行走系统悬架和牵引架,三维空间桁架包括中间平面桁架、侧边平面桁架和若干横向连接梁,侧边平面桁架和中间平面桁架均有两个,中间平面桁架通过横向连接梁连接,两个侧边平面桁架分别连接在中间平面桁架的两侧,两个侧边平面桁架底部具有若干弧形凹槽,侧边平面桁架还具有固定部,固定部用于固定铁路行走系统。通过上述技术方案,解决了现有技术中货运车架减重并可以实现公铁两用的问题。
