The invention relates to a spoke and a wheel comprising the same. The spoke comprises a disc and a side body, the side body comprises a ring surface, an upper circumference and a lower circumference, the upper circumference and the lower circumference are oppositely arranged and are connected with the ring surface, and the upper circumference is connected with the disc; wherein the lower circumference comprises a plurality of first circular arcs and a plurality of second circular arcs, the first circular arcs and the second circular arcs are concentric circular arcs and are distributed at intervals, and the radius of the first circular arcs is larger than that of the second circular arcs. Compared with the prior art, the spoke has the advantages that the lower circumference adopts circular arc distribution with different radiuses, and when the rim and the spoke are subsequently spliced at the second circular arc, the resistance of relative rotation generated by the spoke and the rim can be improved, the torque borne by a welding seam is reduced, and the radial fatigue strength of the wheel is improved.
本发明涉及一种轮辐及包含其的车轮,包括:圆盘与侧体;所述侧体包括环面、上圆周与下圆周,所述上圆周与所述下圆周相对设置且与所述环面相接,所述上圆周与所述圆盘连接;其中,所述下圆周包括若干条第一圆弧与若干条第二圆弧,所述第一圆弧与所述第二圆弧为同心圆弧且间隔分布,所述第一圆弧的半径大于所述第二圆弧的半径。与现有技术相比,本发明的有益效果在于,下圆周采用不同半径的圆弧分布,后续轮辋与轮辐拼接在第二圆弧处时,可提高轮辐与轮辋产生相对转动的阻力,减小焊缝处承受的扭矩,提高车轮径向疲劳强度。
