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, which is prepared by any bogie frame manufacturing method 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, because 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 rate can be improved.

Embodiment 3

[0043] An embodiment of the present application provides a bogie, and the bogie includes the bogie frame provided in the above embodiments.

Abstract

The embodiment of the invention relates to the technical field of railway vehicles, in particular to a railway vehicle, a bogie, a framework and a manufacturing method thereof. The manufacturing method of a bogie framework comprises the steps that determining datum lines of the bogie frame in the transverse direction, the longitudinal direction and the height direction; marking size parameters ofall parts in the bogie frame by taking the datum lines as a reference; and according to the datum lines and the size parameters, manufacturing all parts of the bogie frame. According to the manufacturing method, in the manufacturing process of the bogie frame, the same benchmark is adopted for all parts, consistency and continuity of the benchmark are achieved, benchmark unification is guaranteed,manufacturing errors can be reduced, then the product quality is guaranteed, and the manufacturing cost is reduced.

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...
