Wherein:
in step S1, the journal bracket blank 1 is not subjected to the processing of the caliper mounting surface S2, the hub mounting surface S1, the hub mounting hole a, and the caliper mounting hole b.
In step S3, the machining sequence of the hub mounting surface S1 and the caliper mounting surface S2 is not limited, for example, the caliper mounting surface S2 may be machined first, and then the hub mounting surface S1 may be machined; or the hub mounting surface s1 may be machined first, and then the hub mounting surface s1 may be machined;
in step S4, the machining sequence of the hub mounting hole a and the caliper mounting hole b is not limited either, for example, the hub mounting hole a may be machined first, and then the caliper mounting hole b may be machined; or the caliper mounting hole b may be machined first, and then the hub mounting hole a may be machined.

In addition, in order to ensure that the journal bracket blank 1 and the torsion beam body 2 can be stably positioned at the welding position in the welding process, a welding positioning hole c is correspondingly processed on the journal bracket blank 1 and the torsion beam body 2 for positioning components such as a positioning pin to pass through.
As can be seen from fig. 4 to 6, in the present application, the welding positioning hole c is located at the position of one of the caliper mounting holes b, and the diameter of the welding positioning hole c is smaller than that of the caliper mounting hole b, so that the caliper mounting hole b can be machined on the basis of the welding positioning hole c after the axle diameter bracket blank 1 is welded to the torsion beam body 2, and the influence of the welding positioning hole c on the structure of the axle bracket is avoided.
