Embodiment Construction

[0031] The present invention will be further described in conjunction with specific embodiments now.

[0032] see figure 1 , figure 2 Shown:

[0033] 1. The fixing ring is welded on the first round tube 1 by electron beam welding to form a round tube assembly, and the first round tube is a short round tube;

[0034] 2. The plate is bent into a U-shaped bent plate 4, and the U-shaped bent plate 4 and the straight plate 5 are welded into a column 2;

[0035] 3. The upper end surface of the column 2 is welded with the round tube assembly in step 1 by circumferential welding;

[0036] 4. Weld the two assemblies in step 3 on both sides of the second round tube 3, the second round tube is a long round tube.

[0037] 5. The finished shaft head is connected to the fixed ring by bolts.

[0038] In a specific embodiment, the liftable intermediate support shaft and axle housing assembly is made of tailor-welded round tube profiles and bent plates; it includes a first round tube 3, ...

Abstract

The invention relates to a liftable intermediate support shaft axle housing assembly and a manufacturing method thereof, which are formed by welding a round pipe profile and a bent plate. The axle housing assembly includes a first round tube, a vertical column, and a second round tube, and the first round tube and the second round tube are respectively a short round tube and an long round tube. The bending plate is used as a column on both sides, and the two short round tubes are supported on both sides of the long round tube; the shaft heads or fixing rings are welded on both sides of the short round tube; the short round tube and the column are fixed by surrounding welding; the columns are perpendicular to the short round tube respectively Tube, long round tube. The fixing ring and the short round tube are fixed together by electron beam welding, and then connected with the finished shaft head by bolts. The beneficial effect of the present invention is that it is suitable for the middle liftable support shaft, and can meet the requirements of large drop, light weight and reliability while effectively reducing the development cost.

Description

technical field [0001] The invention belongs to the field of vehicle axles, and in particular relates to an axle housing assembly and a manufacturing method thereof, in particular to an intermediate liftable support shaft axle housing assembly and a manufacturing method thereof. Background technique [0002] At present, the forming forms of the axle housing assembly that can be lifted in the middle are mostly forged curved beams, bent round tubes and tailor-welded square tubes. Among them, forged curved beams have high development and manufacturing costs and heavy quality; bent round pipes are limited by the forming process and have a small drop; tailor-welded square pipes have low production efficiency and poor reliability. [0003] Therefore, it is necessary to design an axle housing suitable for the middle liftable support shaft to meet the requirements of large drop, low cost, low weight and high reliability. Contents of the invention [0004] The invention aims at th...
