Abstract
The utility model relates to a driving mechanism for an electric moped. The driving mechanism comprises a shell, a pedal rod, a motor, a speed reducer and a power synthesis mechanism, wherein the pedal rod is rotationally arranged in the shell; the two ends of the pedal rod are connected with pedals of the electric moped and the power synthesis mechanism respectively; the motor is arranged in the shell, and is connected with the power synthesis mechanism through the speed reducer. A motor output shaft is coaxial with a rotating shaft of a resonant speed reducer in order to improve the working status of the entire mechanism. Output power of the motor is transmitted to the rotating shaft of the resonant speed reducer in a coupling manner, and the rotating shaft is used for driving a flexible bearing and a flexible wheel to rotate. The mechanism is fixed by adopting a rigid wheel, thus the output rotating speed of the flexible wheel is 1/i times of the rotating speed of the motor, and meanwhile the torque is amplified by i times. By adopting the power synthesis mechanism, motion interference is eliminated, and respective power is output through the power synthesis mechanism.
