The invention discloses a side beam bearing articulated chassis in a railway and a railway wagon, solves the problems of limited load and large dead weight of an articulated chassis in the prior art, and has the beneficial effects of reasonable structural arrangement, reduction of bending moment at a middle beam structure and guarantee of load of the chassis. According to the specific scheme, the side beam bearing joint type chassis in the railway comprises at least two chassis assemblies, every two adjacent chassis assemblies are connected through a joint connector, each chassis assembly comprises an end traction and bolster structure, the end traction and bolster structures are located at one ends of the chassis assemblies, and connecting beams are arranged at the other ends of the chassis assemblies; the connecting beam is connected with the two sides of the end traction and bolster structure through side beams respectively, the connecting beam is connected with the middle of the end traction and bolster structure through a middle beam structure, a cross beam structure is transversely connected between the middle beam structure and the side beams, the middle beam structure comprises at least two longitudinal beams, and a set distance is arranged between every two adjacent longitudinal beams.

    本发明公开了一种铁路中侧梁承载关节式底架及铁路货车,解决了现有技术中关节式底架存在载重受限、自重较大的问题,具有结构设置合理,降低中梁结构处的弯矩,保证底架的载重的有益效果,具体方案如下:一种铁路中侧梁承载关节式底架,包括至少两组底架组成,相邻两组底架组成之间通过关节连接器连接,每一底架组成包括端牵枕结构,端牵枕结构位于底架组成的一端,底架组成另一端设置连接梁,连接梁与端牵枕结构的两侧分别通过侧梁连接,连接梁与端牵枕结构的中部通过中梁结构连接,中梁结构与侧梁之间横向连接有横梁结构,中梁结构包括至少两条纵梁,相邻两纵梁之间间隔设定距离。
