Machining method of steel wheel spoke notch structure, steel wheel and vehicle

The invention relates to a machining method of a steel wheel spoke notch structure, a steel wheel and a vehicle. The machining method comprises the steps that a spoke with a notch is placed on a lower die to be positioned; and the upper die is controlled to move downwards till the die is closed, and the upper die and the lower die are used for extruding the notch till the thickness is reduced and the height is increased. The spoke notch is thinned through extrusion, so that the height of the notch can be increased, the matching length of the spoke and the rim at the notch is increased, the problems of notch light leakage caused by machining errors and end diameter jumping out-of-tolerance caused by the fact that the matching surface of the rim and the spoke is not long enough are solved, and meanwhile cost and weight cannot be increased. 本发明涉及一种钢车轮轮辐豁口结构的加工方法、钢车轮及车辆，其包括：将带有豁口的轮辐放至下模上进行定位；控制上模下行至模具闭合，利用上模和下模挤压所述豁口至厚度变薄且高度增高。通过对轮辐豁口采取挤压变薄的方式，可以增高豁口高度，从而使轮辐轮辋在豁口处配合长度增加，解决了因加工误差导致的豁口漏光及轮辋轮辐配合面不够长而造成的端径跳超差问题，同时也不会
