Abstract

The invention provides a railway wagon bogie and a railway wagon with the same, the railway wagon bogie comprises a side frame, the side frame is provided with a mounting hole extending in the horizontal direction, and the mounting hole penetrates through the side wall of the side frame; a swing bolster, wherein a mounting groove extending in the vertical direction is formed in the side wall of the swing bolster, the swing bolster penetrates through the mounting hole, the side frame is inserted into the mounting groove, a stopping piece is arranged between the side wall of the mounting groove and the side frame, and the swing bolster is in clearance fit with the side frame through the stopping piece so as to limit the swing bolster to rotate relative to the side frame in the horizontal direction. Through the railway wagon bogie provided by the invention, the problem that the operation quality of the bogie in the related technology is relatively poor can be solved.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a railway freight car bogie and a railway freight car with the bogie. Background technique [0002] Such as figure 1 As shown, the bogie of the railway freight car includes side frame 10, bolster 20, center disc assembly 40, cam assembly 50, side bearing and damping spring, adopts center plate assembly 40 and Bypass connection. Wherein, the bolster 20 and the side frame 10 are connected by a wedge assembly 50 and a shock-absorbing spring, and the bolster 20 and the railway wagon body can be relatively rotated through the center plate assembly 40, and between the bolster 20 and the side frame 10 The bolster 20 and the side frame 10 can also rotate horizontally relative to each other through the longitudinal relative movement of the wedge assembly 50 and the damping spring. [0003] In the related art, there is no reliable rotational constraint between the bolster 2...
