The invention provides an automatic internal transmission. The automatic internal transmission comprises a hub shaft, an input mechanism, an output mechanism, a speed change mechanism and an automatic gear shifting control mechanism. The speed change mechanism comprises a first planetary gear train and a second planetary gear train; the automatic gear shifting control mechanism comprises a centrifugal block and a clutch control unit, the centrifugal block is connected with the output mechanism, and the centrifugal block is connected with the clutch control unit; the centrifugal block can rotate to a first state along a first direction relative to the output mechanism to drive the clutch control unit to rotate, so that the driving force is transmitted through the first planetary gear train; the centrifugal block can further rotate to a second state in the first direction relative to the output mechanism, the clutch control unit is driven to further rotate, and the driving force is transmitted through the second planetary gear train. The invention further provides a bicycle. According to the automatic inner transmission and the bicycle, the gear shifting phenomenon cannot occur in the gear adjusting process, and the riding experience of a rider is better guaranteed.
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。
