The invention relates to a motor vehicle aluminum alloy wheel with a Udercut weight reduction structure on the inner side of a rim and a machining strengthening method of the motor vehicle aluminum alloy wheel. Compared with a traditional spoke weight reduction structure, the Udercut weight reduction structure has the advantages that the machining process is more advanced, and the light weight is more remarkable. In addition, tests prove that the fatigue life of the wheel with the Udercut weight reduction structure is better than that of a wheel with a spoke weight reduction structure. According to the machining method, a special groove cutter is added, and special machining process parameters are adopted, so that the Udercut weight reduction structure is obtained. The spinning machining method is added, the roller spinning technology is adopted, the strength and hardness of the Udercut weight reduction structure are improved, and perfect balance between weight reduction and mechanical strength is achieved. Compared with a traditional spoke weight reduction structure, the Udercut weight reduction structure has the advantages that the machining process is more advanced, and the light weight is more remarkable. In addition, tests prove that the fatigue life of the wheel with the Udercut weight reduction structure is better than that of a wheel with a spoke weight reduction structure.

    本发明涉及一种轮缘内侧具有Udercut减重结构的机动车铝合金车轮及其加工强化方法。Udercut减重结构与传统轮辐减重相比较,其加工工艺更先进,轻量化更显著。而且,经试验验证,Udercut减重结构车轮疲劳寿命优于轮辐减重车轮。机加工加工方法是增加专用沟槽刀具,采用专用机加工艺参数,获得Udercut减重结构。增加旋压加工方法,采用辊轮旋压工艺,提高Udercut减重结构的强度及硬度,做到减重和机械强度之间完美平衡。Udercut减重结构与传统轮辐减重相比较,其加工工艺更先进,轻量化更显著。而且,经试验验证,Udercut减重结构车轮疲劳寿命优于轮辐减重车轮。
