本发明提供了一种自动内变速器,其包括花毂轴、输入机构、输出机构、变速机构及自动换档控制机构;变速机构包括第一行星轮系及第二行星轮系;自动换档控制机构包括离心块及离合控制单元,离心块与输出机构连接,且离心块与离合控制单元连接;离心块可相对于输出机构沿第一方向转动至第一状态,带动离合控制单元转动,使驱动力经第一行星轮系传递;离心块还可相对于输出机构沿第一方向进一步转动至第二状态,带动离合控制单元进一步转动,使驱动力经第二行星轮系传递。本发明还提供了一种自行车。本发明的自动内变速器及自行车在档位调节过程中不会出现“越档”的现象,更好的保障了骑行者的骑行体验。

    An automatic internal transmission (100), comprising a hub shaft (10), an input mechanism (20), an output mechanism (30), a transmission mechanism (40), and an automatic shift control mechanism (50). The transmission mechanism (40) comprises a first planetary gear train (41) and a second planetary gear train (42). The automatic gear shifting control mechanism (50) comprises a centrifugal block (501) and a clutch control unit (53), the centrifugal block (501) being connected to the output mechanism (30), and the centrifugal block (501) being connected to the clutch control unit (53). The centrifugal block (501) can rotate relative to the output mechanism (30) to a first state in a first direction, so as to drive the clutch control unit (53) to rotate, so that a driving force is transmitted by means of the first planetary gear train (41). The centrifugal block (501) can further rotate relative to the output mechanism (30) to a second state in a first direction, so as to drive the clutch control unit (53) to further rotate, so that the driving force is transmitted by means of the second planetary gear train (42). A bicycle, comprising a bicycle body and the automatic internal transmission (100).
