Framework and bogie comprising same

Abstract

The invention discloses a framework. The framework comprises a cross beam and a side beam, wherein the side beam is of a sheet structure and hunches up in the center in the longitudinal direction; and the cross beam is connected to the hunching-up top of the side beam and detachably connected with the side beam. The invention further provides a bogie at the same time. The bogie comprises the framework; integration mounting bases are installed on the upper surfaces of the transverse two ends of the cross beam correspondingly; each integration mounting base comprises a foundation seat, a pair of brake mounting seats, a vertical absorber seat and an antiroll device mounting seat, wherein the brake mounting seats are arranged on one side of the foundation seat in the same straight line in a back-to-back mode, the vertical absorber seat is arranged at one end of the other lateral side of the foundation seat, and the antiroll device mounting seat is arranged on the other end of the other lateral side of the foundation seat; and the side beam, the cross beam and the integration mounting bases are in series connection sequentially through fasteners. The problem that a framework made from carbon fiber composite materials is poor in welding property is solved. The longitudinal, transverse and vertical rigidity decoupling of the side beam and the cross beam is achieved. The framework and the bogie have the advantages that the structure and assembling process of the bogie are simplified, and the loading burden of the framework is relieved.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a frame and a bogie. Background technique [0002] The general frame is an integral welded or cast structure, the beam is a steel pipe structure or a box beam structure, the side beam is a fish-belly box beam structure, the middle of the side beam is concave, and the side beam and the beam are integrally formed. [0003] The existing bogie structure mainly has the following defects: [0004] 1. The frame adopts an integrated structure, and there is stiffness coupling between the side beam and the cross beam. [0005] 2. The frame itself will bear a relatively large force, and the braking device of the existing structure is transmitted to the frame through the brake mounting seat during the braking process, which brings a greater load burden to the frame. [0006] With the increase of train speed, some special requirements are put forward for the light weight of ro...

[0005] 2. The frame itself has to bear a large force, and the braking device of the existing structure is transmitted to the frame through the brake mounting seat during the braking process, which brings a greater load burden to the frame

If composite materials are used to manufacture the frame, its welding performance is poor, and how to manufacture and assemble various parts to meet the requirements is a big problem
