Abstract

The invention discloses a railway wagon and an underframe assembly thereof. The underframe assembly comprises a supporting beam assembly, coupler mounting structures, and end part cuffs. The coupler mounting structures arranged on two ends of the supporting beam assembly and are used for being connected with the adjacent underframe assembly through the couplers. Each of the end part cuffs is fixedly connected with the supporting beam assembly, and is disposed on one side of each of the coupler mounting structures far away from the supporting beam assembly, the end part cuffs are provided withavoiding ports used for the coupler mounting structures, and the end part cuffs are provided with accommodation grooves capable of accommodating the couplers. The underframe assembly is provided withthe supporting beam assembly, so that the bearing capacity and the loading capacity are obviously improved; meanwhile, the combination of the end sleeve opening with the supporting beam assembly is adopted, the couplers can be installed in the accommodating groove of the end part cuffs, the length of the underframe cannot be increased, the increase of the length of the underframe assembly is effectively prevented, transmission efficiency of longitudinal force is obviously improved, and the couplers are guaranteed to be provided with reasonable installation space.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a railway freight car and its undercarriage assembly. Background technique [0002] At present, the underframe assembly of railway freight cars can be divided into two main types: with center beam and without center beam. Among them, in the underframe assembly with center beam, the center beam is a structure with front and rear cluster plate seats. In the underframe assembly without center beam structure, the bearing performance is poor, and the longitudinal force transmission performance is poor, which leads to the restriction of the load capacity and longitudinal force transmission of the vehicle. In the underframe assembly without center beam structure, relatively Adjacent underframes are connected to each other through couplers, and the rear and end dimensions of the coupler are large, the middle dimension is small, and the coupler swing angle is large. If the ...
