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 automatic gear shifting control mechanism comprises a centrifugal block, a clutch control unit, an elastic reset piece, an adjusting piece and a driving piece. The centrifugal block is connected with the output mechanism, and the clutch control unit is connected with the centrifugal block; the elastic reset piece is used for providing restoring force for the centrifugal block through self-elasticity. The adjusting piece is connected with the elastic resetting piece; the driving piece is connected with the output mechanism and the adjusting piece, and the driving piece can drive the adjusting piece to operate to change the deformation state of the elastic reset piece so as to change the restoring force borne by the centrifugal block. Meanwhile, the invention further provides a bicycle. Compared with the prior art, the automatic internal transmission and the bicycle can adjust the restoring force applied to the centrifugal block by the elastic reset piece, so that gear shifting and speed changing can be achieved at different rotating speeds, and the riding requirements of a rider are better met.

    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;自动换档控制机构包括离心块、离合控制单元、弹性复位件、调节件及驱动件;离心块与输出机构连接,离合控制单元与离心块连接;弹性复位件用以通过自身弹力为离心块提供恢复力;调节件与弹性复位件连接;驱动件与输出机构、调节件连接,且驱动件可带动调节件运行,改变弹性复位件的形变状态,以改变离心块所受的恢复力。同时,本发明还提供了一种自行车。与现有技术相比,本发明提供的自动内变速器及自行车可以调节弹性复位件对离心块所施加的恢复力大小,从而使得换档变速可以在不同转速下实现,更好的满足了骑行者的骑行需求。
