The invention discloses a dual-mode two-speed hub motor, and relates to the field of hub motors. The dual-mode two-speed hub motor is characterized in that: a second-gear clutch assembly connected with an end cover is arranged between a second-gear motor planetary speed reduction assembly and a pedal second-gear input piece, and the second-gear clutch assembly is connected with a centrifugal driving assembly; the centrifugal driving assembly limits or releases the second-gear clutch assembly according to the rotating speed of the end cover, and therefore transmission between the second-gear motor planetary speed reduction assembly and the end cover and transmission between the pedal second-gear input piece and the end cover are controlled. The dual-mode two-speed hub motor has a pedal input mode and an electric input mode, and each mode comprises two speed change gears, so that the working efficiency of the motor can be improved; and automatic gear shifting is realized according to the output speed in the two modes, so that the riding experience can be improved, and the service life of the motor is prolonged.
本发明公开了一种双模两速轮毂电机,其涉及轮毂电机领域。其技术方案要点包括:第二挡电机行星减速组件与脚踏二挡输入件之间设置有与所述端盖连接的二挡离合组件,所述二挡离合组件连接有离心驱动组件;所述离心驱动组件根据所述端盖的转速来对所述二挡离合组件进行限制或者释放,从而控制所述第二挡电机行星减速组件与端盖之间、以及所述脚踏二挡输入件与端盖之间的传动。本发明包括脚踏输入和电动输入两种模式,而且每种模式均包括两个变速挡位,从而能够提高电机的工作效率;而且两种模式下均根据输出速来实现自动换挡,从而能够提高骑行体验,并延长电机的使用寿命。
