The invention provides a wheel and a manufacturing method thereof, a wheel assembly and an automobile, and relates to the technical field of automobile manufacturing. The wheel comprises a rim and a spoke. By limiting a microcosmic grain size and a grain size change trend at a contact interface of the rim and the spoke, performance of a welding part of the rim and the spoke is basically consistentwith that of a body, and the manufactured wheel has excellent mechanical performance and meets performance requirements of national and industrial standards for the wheel. According to the manufacturing method of the wheel, the rim and the spoke are welded through rotary friction welding to obtain the wheel, and the obtained wheel has excellent mechanical performance by limiting a welding mode ofrotary friction welding and technological parameters such as a welding surface linear speed, upsetting pressure and the like in the rotary friction welding process; and meanwhile, the manufacturing method is short in time in the whole welding process and high in welding efficiency so that production efficiency of the wheel is obviously improved, and the manufacturing method is suitable for industrial mass production.
本发明提供了一种车轮及其制造方法、车轮总成和汽车,涉及车辆制造技术领域。该车轮包括轮辋和轮辐,通过对轮辋和轮辐接触的界面处微观晶粒尺寸以及晶粒尺寸变化趋势的限定,使得该轮辋和轮辐焊接的部位与本体性能基本一致,所制得的车轮具有优良的机械性能,满足国家及行业标准对于车轮的性能要求。本发明提供了上述车轮的制造方法,采用旋转摩擦焊将轮辋和轮辐进行焊接得到车轮,通过对旋转摩擦焊这一焊接方式以及旋转摩擦焊过程中焊接面线速度和顶锻压力等工艺参数的限定,使得所得到的车轮具有优良的机械性能;同时,该制造方法在整个焊接过程时间短,焊接效率高,从而使得车轮的生产效率明显提高,适合于工业上大批量生产。
