Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] The driving mechanism of the electric bicycle includes a housing 1, a pedal rod 2, a motor 3, a reducer 4 and a power synthesis mechanism 5. The pedal rod 2 is rotatably arranged in the housing 1, and the two ends of the pedal rod are respectively connected to the The pedals of the electric bicycle are connected to the power synthesis mechanism, and the motor 3 is placed in the housing and connected to the power synthesis mechanism 5 through the reducer 4 .
[0018] The power synthesis mechanism 5 includes a sprocket 51, a first one-way wheel 52 and a second one-way wheel 53, and a ratchet 54 that are rotatably arranged in the housing, and the ratchet is rotatably arranged in the housing, and the outer ring of the ratchet and the sprocket The inner ring of the first one-way wheel 52 and the second one-way wheel 53 are coaxially and rotatably arra...

The invention relates to a driving mechanism of an electric power-assisted vehicle, which includes a housing, a pedal rod, a motor, a speed reducer and a power synthesis mechanism. The pedal is connected with the power synthesis mechanism, and the motor is placed in the housing and connected with the power synthesis mechanism through the speed reducer. In the present invention, the output shaft of the motor and the rotating shaft of the harmonic reducer are in a coaxial structure to improve the working conditions of the entire mechanism. In this patent, the output power of the motor is transmitted to the rotating shaft of the harmonic reducer in a coupled manner, and then The latter drives the flexible bearing and the flex spline to rotate. Since the rigid spline of this mechanism is fixed, the output speed of the flex spline is 1 / i times the motor speed, and the torque is amplified by "i" times; due to the use of a power synthesis mechanism, they are mutually The movements between them do not interfere with each other, and the power generated by each can be output through the power synthesis mechanism.
Description
technical field [0001] The invention relates to the field of electric bicycles, in particular to a driving mechanism of electric bicycles. Background technique [0002] For electric mopeds, there are two kinds of power, one is the output power of the motor, which drives the sprocket to rotate, so that the whole vehicle moves forward; the other is the way of human pedaling, which can also make The sprocket turns, causing the car to move forward. The transmission efficiency of the driving mechanism of the existing electric bicycle is low, the damage to the motor between start and stop is relatively large, and there is more or less interference between the transmission mechanisms corresponding to the above two riding modes of the existing electric bicycle, so that The efficiency of electric energy utilization is low when electric driving, and it is more laborious when manpower is riding. Contents of the invention [0003] The purpose of the present invention is to solve the...
