The invention discloses a multi-gear adjustable speed change mechanism, and relates to the field of power-assisted bicycles. According to the technical scheme, the gearbox comprises a middle shaft, an output shell, an input sleeve, a planetary gear assembly and a gear shifting adjusting assembly. The planetary gear assembly integrated with the three sun gears in the speed change mechanism can achieve five-gear speed change, so that the axial size can be optimized, the speed change mechanism can be conveniently integrated in the hub motor, the number of gears is increased, and therefore the riding experience can be optimized; meanwhile, the first gear and the second gear are in speed reduction transmission, so that starting during riding can be facilitated, and the riding experience is further optimized.

    本发明公开了一种多挡可调变速机构,其涉及助力自行车领域。其技术方案要点包括中轴、输出壳体、输入套筒、行星齿轮组件以及换挡调节组件。本发明变速机构中集成有三个太阳轮的行星齿轮组件能够实现五挡变速,这样能够优化轴向尺寸,方便将变速机构集成于轮毂电机内,而且增加了挡位数量,从而能够优化骑行体验;同时,一挡和二挡为降速传动,这样能够方便在骑行时起步,进而优化骑行体验。
