Abstract

The embodiment of the invention provides a bogie. The bogie comprises a rigid framework, an adaptive seat and a brake clamp unit, wherein the rigid framework comprises two rigid side beams and a rigidcross beam, and the cross beam is welded between the two side beams; the adaptive seat is fixed to the side beam, the adaptive seat is provided with a clamp mounting hole, the length direction of theclamp mounting hole is parallel to the reference surface, wherein the reference surface is a coordinate surface determined by the movement direction and the gauge direction of the bogie; and the brake clamp unit comprises a cylindrical lever hanging seat pin, and the lever hanging seat pin is connected into the clamp mounting hole in a sleeved mode. According to the bogie, the technical problem of poor mounting stability of the brake clamp unit of the bogie is solved.

Description

technical field [0001] The present application relates to the technical field of rail trains, in particular to a bogie. Background technique [0002] figure 1 A schematic diagram of an existing bogie. Such as figure 1 As shown, the existing bogie includes a frame 3, a brake hanger 1 and a brake caliper unit 4; wherein, the brake hanger adopts a cantilever structure welded to the frame beam, and the brake caliper unit adopts a four-point suspension The hanging structure and the cantilever structure of the frame beam are installed through bolts and brake caliper unit mounting holes 11, and the length directions of the bolts and brake caliper unit mounting holes 11 are all perpendicular to the ground. Therefore, the gravity of the brake caliper unit, the load brought by the movement of the bogie and the braking load brought by the braking of the brake unit are all carried by the bolts, resulting in poor force on the bolts and easy damage, that is, the installation of the bra...
