Abstract

The invention relates to a high strength automobile aluminium alloy wheel rim, in particular to an automobile wheel rim matched with oversize vehicles. The high strength automobile aluminium alloy wheel rim is made of high strength aluminium alloy material which comprises main chemical elements with the mass percent: 0.4-0.8% of Si, 0.8-1.2% of Mg, 0.16-0.22% of Ti, 0.2-0.3% of Zn, 0.6-0.8% of Fe,0.15-0.4% of Cu, 0.04-0.35% of Cr, 0.1-0.2% of Mn, 0.02-0.03% of Sb, 0.02-0.03% of Sr and the rest of Al. The automobile aluminium alloy wheel rim has high tensile strength which is 10% higher than that of the existing aluminium alloy wheel rim produced by 6061-T6, is good in mechanical property, enhances the rotatable performance of alloy when the structure is refined, and has the advantages ofwide application scope, low production cost and easy popularization and use.

Description

【Technical field】: [0001] The invention relates to an automobile wheel rim, in particular to a high-strength automobile aluminum alloy wheel rim matched with a large vehicle. 【Background technique】: [0002] The rim is the part that fixes and installs the tire in the wheel. It belongs to the automobile security parts. The rim structure has two-piece, three-piece, four-piece, five-piece, etc., and the most commonly used ones are two-piece and three-piece. Wheel rims can be divided into steel rims and aluminum alloy rims according to their manufacturing materials. At present, steel rims are generally used at home and abroad. These steel rims are manufactured by section steel processing or plate rolling. The material grades are 12LW-GB11262-89, BG380CL, etc., among which the tensile strength of the 12LW-GB11262-89 material is σ b It is 355-470MPa, and the elongation is >30%. Compared with steel rims, aluminum alloy rims have absolute advantages in light weight, heat dissip...
