The invention provides a ratchet wheel hub and a bicycle, relates to the technical field of bicycle accessories, and solves the technical problems that bottom teeth of a hub main body are easily separated from upper teeth of a ratchet wheel main body, and transmission of influence force is affected. The ratchet wheel hub comprises a hub body, a ratchet wheel body, a bottom tooth part connected with the hub body and an upper tooth part connected with the ratchet wheel body, one of the bottom tooth part and the upper tooth part is provided with an insertion part, the other one of the bottom tooth part and the upper tooth part is provided with a concave part, the insertion part is provided with first oblique teeth, and the concave part is provided with second oblique teeth. And when the insertion part extends into the concave part and is inserted into the concave part in place, the first helical teeth can be meshed with the second helical teeth. Through the matching structure of the insertion part and the concave part, the stability of the structure can be improved, the bottom tooth part and the upper tooth part are prevented from being disengaged due to strong take-off and the like, and stable transmission of torque is facilitated.

    本发明提供了一种棘轮花鼓及自行车,涉及自行车配件技术领域,解决了花鼓主体的底齿与棘轮主体的上齿之间容易脱离,影响力的传输的技术问题。该棘轮花鼓包括花鼓主体、棘轮主体、与花鼓主体相连接的底齿部、与棘轮主体相连接的上齿部,底齿部和上齿部两者中,其中之一上设置有插入部,其中另一上设置有凹陷部,插入部上设置有第一斜齿,凹陷部上设置有第二斜齿,插入部伸入凹陷部内并与凹陷部插接到位时,第一斜齿能与第二斜齿相啮合。插入部与凹陷部的配合结构,能够提高结构的稳定性,防止底齿部与上齿部因强力起跳等而发生脱齿,便于力矩的稳定传输。
