The invention provides an unequal-thickness steel wheel and a manufacturing method thereof. The manufacturing method of the unequal-thickness steel wheel comprises the following steps that the unequal-thickness steel wheel is divided into at least two areas, and the at least two areas correspond to different positions of the unequal-thickness steel wheel respectively and have different thickness requirements; according to different thickness requirements, required steel plates are cut, and the thickness and the size of the steel plates are matched with those of the at least two areas; and the steel plate is machined through an unequal-thickness forming technology to form the unequal-thickness rim and spoke assembly. The variable-section wheel is designed, the steel plate is machined through the unequal-thickness forming technology, the rigidity of the rim and the spoke is variable, the NVH performance of a whole vehicle using the steel wheel is improved, and noise in the vehicle is effectively reduced; and compared with an equal-thickness steel wheel, optimal distribution of weight and rigidity is achieved.

    本申请提供一种不等厚钢轮及其制造方法。不等厚钢轮的制造方法包括以下步骤:将不等厚钢轮划分为至少两个区域,至少两个区域分别对应不等厚钢轮的不同位置并且具有不同的厚度要求;根据不同的厚度要求,切割所需的钢板,钢板的厚度及尺寸与至少两个区域相匹配;采用不等厚成型工艺对钢板进行加工以形成不等厚的轮辋轮辐组件。本申请通过设计变截面的车轮,采用不等厚成型工艺对钢板进行加工,实现了轮辋轮辐的刚度可变,不但提升了使用钢轮的整车NVH性能,有效降低车内噪音;相对于等厚度钢轮,实现重量和刚度的最优分配。
