The invention discloses a speed control system, a hub motor and an agricultural unmanned vehicle, and belongs to the technical field of transmission equipment. The speed change system adopts the spherical roller as a transmission body of the input and output structure, and is provided with the centrifugal part which does centrifugal motion along with the actual rotating speed of the output structure, and the self-adaptive adjustment of the transmission ratio and the stepless speed change are realized along with the change of the position of the centrifugal part and the change of the inclination angle of the first axis of the spherical roller. According to the hub motor and the agricultural unmanned vehicle, the centrifugal mechanism can be matched with the spherical roller capable of doing precession motion, the transmission ratio can be adjusted in a self-adaptive and stepless mode, the output characteristic of the motor with the fixed transmission ratio can be achieved through the motor with the smaller power, cost is reduced, and self-adaptive speed regulation can be achieved in various scenes.

    本发明公开一种变速系统、轮毂电机以及农业无人车,属于传动设备技术领域。该变速系统采用球形滚子作为输入输出结构的传动体,并设置了随输出结构实际转速的作离心运动的离心件,随着离心件位置的变化,球形滚子第一轴线倾斜角度变化,实现传动比的自适应调整,实现无级变速。该轮毂电机以及农业无人车,可以通过离心机构与可作进动运动的球形滚子配合,实现自适应地、无级地调整传动比,可通过更小功率电机实现传动比固定的电机的输出特性,降低成本,并且可以在多种场景下实现自适应调速。
