The invention discloses a rim spoke connecting structure which comprises a spoke body and a tooth cap capable of being connected with a rim in a matched mode, a taper section with the small inside and the large outside is arranged on the peripheral face of one end of the spoke body, a through tooth cap mounting hole is formed in the tooth cap, the inner diameter of the tooth cap mounting hole is matched with the minimum outer diameter of the taper section, and the tooth cap is fixedly sleeved on the taper section through the tooth cap mounting hole. The tooth cap mounting hole is tightly meshed with the spoke taper section, the minimum outer diameter of the taper section is matched with the inner diameter of the tooth cap mounting hole, in the moving process, the tooth cap is extruded by the taper section to generate micro deformation, the outward extrusion force on the nut matched with the tooth cap is increased, the more the tooth cap moves towards the tail end of the spoke, the more the extrusion force is increased, the wheel set fault caused by the fact that the nut is loosened and falls off from a tooth cap due to vibration of the spoke in the riding process is effectively prevented, and compared with a coating degumming prevention method, the preparation process is simple, and the cost is low.
本发明公开了一种车圈辐条的连接结构,包括辐条本体和一能配合连接车圈的牙帽,所述辐条本体的一端外周面设有内小外大的锥度段,所述牙帽设有贯穿的牙帽安装孔,所述牙帽安装孔内径与所述锥度段的最小外径相适配,所述牙帽通过所述牙帽安装孔固定套接在所述锥度段上。本发明提供一种牙帽安装孔与辐条锥度段紧密啮合,由于锥度段的最小外径与所述牙帽安装孔内径相适配,在移动过程中,牙帽受锥度段的挤压产生微变形,导致对与其相适配的螺帽向外的挤压力增加,越往辐条末端移动,挤压力越增加,有效的预防了骑行过程中由于辐条震动导致螺帽松动从牙帽上脱落,从而造成轮组故障,且其相比涂覆防脱胶的方法,制备工序简单,成本低。
