Abstract
The invention relates to a planetary automatic shifting system of a unilateral clutch hub motor. The invention uses the principle that the forward rotation and the backward rotation of the motor can produce different torques and rotate speeds, and the output rotation direction is forward. The invention consists of a shift switch, a timing shift linkage switch, a singlechip shift controller, a forward and backward rotate buffer, a motor driver, an electromagnetic brake, a planetary bracket rotating shaft, a sun wheel, a planetary gear, a planetary outer gear ring unilateral clutch, a left unilateral clutch rotating shaft, a left unilateral clutch body, a motor rotor, a motor stator, a motor hub, a right unilateral clutch rotating shaft, and a right unilateral clutch body. When the control system electrifies the motor with different-direction current, the forward rotation and the backward rotation of the motor drive the automatic shifting system to work, and the purposes of timing and moment-changing are achieved. The output rotation direction always rotates in the forward direction, thereby the hub motor is caused to possess the automatic timing function.
