The invention provides a spoke and a manufacturing method. The spoke comprises a spoke body, bolt holes, heat dissipation holes and reinforcing pieces. The bolt holes and the heat dissipation holes are all formed in the spoke body, and the reinforcing pieces cover the positions, where the bolt holes are formed, of the surface of the spoke body through friction welding and are provided with throughholes matching the bolt holes. The spoke and the manufacturing method have the beneficial effects that (1) during spoke forming, the thickness of a plate is small, only bolt holes are locally reinforced, the weight reduction effect of the spoke is good, and the light weight ratio is 20% or above; (2) the corresponding manufacturing method of the designed product is simple, the production efficiency is high, the spoke adopts a cold stamping process, and the production efficiency is improved by more than 10 times compared with a spinning process; and (3) the production process saves raw materials, the bolt hole local reinforcing pieces and the spoke bottom of the spoke are welded into a whole, the reinforcing effect is good, the fatigue life is long, the production efficiency is remarkable,and the cost is reduced.
本发明提供一种轮辐及制造方法,包括:轮辐本体、螺栓孔、散热孔及加强片;所述螺栓孔与散热孔均开设于所述轮辐本体上,所述加强片通过摩擦焊覆盖在所述轮辐本体表面的所述螺栓孔开设处且设有与所述螺栓孔相配合的通孔。本发明的有益效果在于:(1)轮辐成型时板料厚度薄,且只在螺栓孔局部进行加强、轮辐降重效果好,轻量化比例20%以上;(2)设计的产品相应的制造方法简单,生产效率高,轮辐采用冷冲压工艺,相比旋压工艺生产效率提高10倍以上;(3)该生产工艺在节省原材料、螺栓孔局部加强片与轮辐辐底焊接为一个整体,加强效果好,疲劳寿命高生产效率有显著优势,降低成本。
