Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lightweighting, and particularly to a lightweight tube beam assembly component. Background Art

[0002] Conventional tube beam assemblies of market regular heavy-duty tractors usually entirely adopt steel structures or adopt a combination of American aluminum alloy + steel structures. The steel tube beam assembly is welded between steel brackets to form the tube beam assembly. The weight of the tube beam assembly is relatively large, and the precision control of the tube beam assembly and the assembly precision control of the products carried thereon require high costs. For the tube beam assembly made of a combination of American aluminum alloy + steel structures, the weight of the tube beam assembly is lighter than that of the steel tube beam. The steel brackets are connected by welding, and the American aluminum alloy and the steel structure are usually connected by fasteners. The same control precision requires high costs;
