Embodiment 1

[0026] Please refer to figure 1 , the embodiment of the present application provides a bogie frame manufacturing method, the manufacturing method comprising:

[0027] Step S10, determine the reference line of the bogie frame in the horizontal, longitudinal and height directions; in the actual design, manufacture and assembly process, the horizontal reference line of the bogie frame can be the lateral center line of the bogie frame, and the bogie frame is at The longitudinal reference line may be the longitudinal centerline of the bogie frame, and the reference line of the bogie frame in the height direction may be the axle centerline;

[0028] Step S20, using the reference line as a reference, mark the size parameters of each component in the bogie frame; take the reference line of the bogie frame in the horizontal, vertical and height directions as a reference, and carry out the dimensional parameters of each component in the bogie frame Dimensions, dimension parameters can ...

Embodiment 2

[0040] An embodiment of the present application provides a bogie frame, and the bogie frame is prepared by any one of the bogie frame manufacturing methods provided in the above embodiments. The bogie frame can include a beam composition and a side beam composition; wherein: the beam composition includes two half beams and two longitudinal beams, and the half beam includes a beam vertical plate, a beam upper cover plate and a beam lower cover plate; the side beam composition includes a side beam Riser, side sill top cover and side sill bottom cover.

[0041] When manufacturing the above-mentioned bogie frame, since the same datum is used in the manufacture and assembly of various parts, similarly, the consistency and continuity of the datum can be ensured, the unity of the datum is guaranteed, and the manufacturing error is reduced. , It can also reduce the assembly error, so the product quality can be improved, the manufacturing cost can be reduced and the product qualified r...

Abstract

The embodiments of the present application relate to the technical field of rail vehicles, and in particular, to a rail vehicle, a bogie, a frame and a manufacturing method thereof. The manufacturing method of the bogie frame includes: determining the reference line of the bogie frame in the horizontal direction, the longitudinal direction and the height direction; using the reference line as a reference, marking the size parameters of each component in the bogie frame; According to the reference line and the dimensional parameters, each part of the bogie frame is manufactured. In the manufacturing method of the bogie frame, all components use the same reference, which realizes the consistency and continuity of the reference, ensures the uniform reference, reduces manufacturing errors, and thus ensures product quality and reduces manufacturing costs.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular, to a rail vehicle, a bogie, a frame and a manufacturing method thereof. Background technique [0002] At present, with the rapid development of the railway vehicle industry, there are more and more types of bogies, including large railway carbon steel car bogies, high-speed EMU bogies, urban rail bogies, subway vehicle bogies and other bogies. The main frame of the bogie is a frame, and the frame is composed of beams and side beams welded, and the suspension parts and various hangers required for the bogie are welded on the beams and side beams. [0003] The manufacturing method of the existing bogie is as follows: firstly, the beam and the side beam of the box structure are respectively formed by welding steel plates, then the beam and the side beam are butt-welded to form a basic frame, and finally the additional device is welded on the basic frame. However, in t...
