Description

一种复合式辐条 技术领域
本发明涉及一种辐条， λ其是用于自行车或摩托车轮圈的辐条。 背景技术
现有的普通辐条如图 1所示，通常包括端部的弯头部 1、 中部的主体部 2 和另一端的螺牙部 3, 主体部 1截面通常为圓形， 但是这种辐条通常全部是 金属材质， 重量较大， 不能适应一些要求较高场合， 另外也有一些辐条是全 碳纤材质， 如图 2 , 此种辐条虽然重量轻， 但是性能不足， 使用中断裂率较 高 ( 10%甚至以上）。 发明的公开
本发明的目的在于提供一种复合式辐条，在保证强度的基础上降低重量， 防止断裂。
本发明是这样实现的： 一种复合式辐条， 包括弯头部、 主体部和螺牙部， 主体部外表面包覆有碳纤层。
所述主体部外表面开有多条环形槽，主体部沿长度方向截面形成鱼骨状。 所述主体部截面形状为长方形、 椭圓形或者由上下两条横向的平行直线 和左右两条外凸的弧线构成的封闭图形。
所述主体部最大直径大于弯头部与主体部连接位置的直径 , 主体部与弯 头部连接处形成一段正面视图为梯形的连接段；
主体部最大直径大于螺牙部与主体部连接位置的直径， 主体部与螺牙部 连接处形成一段正面视图为梯形的连接段。
所述主体部上开有多个小孔。
附图的简要说明
. 下面结合附图和具体实施方式对本发明作进一步说明。
