The claw disc is made of a carbon fiber material and comprises a disc main body and an annular outer edge formed on the periphery of the disc main body, and a shaft hole is formed in the center of the disc main body; the annular outer edge is provided with a four-hole group structure which is composed of four first lock holes and used for installing a four-corner disc and a five-hole group structure which is composed of five second lock holes and used for installing a five-corner disc, and the front face and the back face of the annular outer edge are both of a flat face structure so that the disc can be installed on the front face and/or the back face of the annular outer edge. The claw disc is made of the carbon fiber material, the compressive strength and the yield strength of the overall structure of the claw disc are better than those of an existing conventional claw disc made of an aluminum alloy material, the claw disc is light in weight, light weight of a product can be achieved easily, the four-corner disc piece or the five-corner disc piece can be installed in a matched mode through the four-hole-group structure and the five-hole-group structure, and the adaption universality of the claw disc is high.
本发明公开一种爪盘及自行车,爪盘由碳纤维材料制成,包括圆盘主体和形成于圆盘主体外周处的环形外缘,圆盘主体的中心处开设有轴孔,环形外缘上开设有一组由四个第一锁孔组成以用于安装四角盘片的四孔组结构和一组由五个第二锁孔组成以用于安装五角盘片的五孔组结构,且环形外缘的正面和背面均为平整面结构,以便在环形外缘的正面和/或背面处安装盘片。本发明的爪盘由碳纤维材料制成,其整体结构的抗压强度和屈服强度都要优于现有常规的铝合金材质的爪盘,且重量轻,有利于实现产品轻量化,且通过四孔组结构和五孔组结构可适配安装四角盘片或五角盘片,其适配通用性强。
