The invention discloses a split type bicycle hub ratchet wheel and a preparation method thereof. The split type bicycle hub ratchet wheel comprises a ratchet wheel cylinder and a ratchet wheel fluted disc seat connected with the ratchet wheel cylinder part, and the ratchet wheel cylinder is designed to be of a cylinder-type structure. The ratchet wheel fluted disc seat is structurally a metal component. According to the bicycle hub ratchet wheel, it can be guaranteed that the ratchets are not damaged, the production process can be simplified, the production cost is reduced, and the coaxiality precision grade of the ratchet wheel is increased; and meanwhile, the weight of the ratchet wheel can be lowered, and ratchet wheel bodies of different specifications can be changed in the production process.

    本发明公开了一种分体式自行车轮毂棘轮及其制备方法,其包含棘轮筒,与棘轮筒部相连接的棘轮齿盘座,所述棘轮筒设计为一筒式结构;所述棘轮齿盘座结构是一个金属构件。本发明的自行车轮毂棘轮,既能保证棘齿不受损,又能简化生产工艺,降低生产成本,提高棘轮同轴度精度等级,同时还能减轻棘轮重量,在生产中可变换不同规格的棘轮体。
