Abstract

The invention relates to a production method of an automobile suspension support arm. The suspension support arm comprises a first support, a second support, a bush component and a spearhead. The bush component comprises a bush and a connecting end. The production method includes arranging the connecting end of the bush component between the first support and the second support; then combining the first support with the second support and welding and fixing the connecting edge of the first support and the second support; then fixing the spear head on the combined entity of the first support and the second support; and finally electrophoretic painting on the welded combined entity. The automobile suspension support arm is firm in welded structure and high in strength; and abrasion-resistance and corrosion-resistance are good by the electrophoretic painted surface, and stability of an automobile system can be improved.

Description

technical field

[0001] The invention relates to the technical field of auto parts, more specifically, the invention relates to an auto suspension support arm and a preparation method thereof. Background technique

[0002] The automobile swing arm assembly is the core component of the automobile suspension system. Its structure is complex and odd-shaped, the product technology content is high, and the production technology is difficult. Under the condition of millions of large load impacts and the safety and reliability meet the requirements of 100%, the physical strength, bending Deformation, shock-resistant and wear-resistant auto parts. The current automobile swing arm assembly has relatively low processing precision, but it is strong and strong, and it is easy to achieve safety and reliability. However, the mid-to-high-end car series swing arm assembly has complex shape, high processing precision, fine structure, and light weight, but it is safer and more reliable. Diff...
