Problems solved by technology

[0002] In my country's electric vehicle market, simple "bicycle + motor" and other light motor vehicles are mistaken for "electric bicycles". The reason is that this product does not comply with the regulations on non-motor vehicles (electric bicycles) in the new "Traffic Law" implemented on May 1, 2004. At present, many cities in our country have banned this type of electric vehicle, and this type of electric vehicle will be marketed soon. completely eliminated

Embodiment Construction

[0012] in figure 1 In this case, the driver [2] is installed in the bottom bracket of the bicycle bracket [1] and runs on the central axis of the bicycle. Drive the bicycle to travel through the chain and mechanical speed change mechanism [4].

[0013] in figure 2 In this, the motor power is transmitted to the power synthesis mechanism [7] through the harmonic reducer [5]. The human power is transmitted to the power synthesis mechanism [7] through the pedals and the bicycle axle [6].

[0014] in image 3 In, the human power is transmitted to the middle ratchet wheel [10] through the ratchet ring [8] of the power synthesis mechanism, and the motor power is transmitted to the middle ratchet wheel [10] through the ratchet core [11]. The middle ratchet transmits the synthetic power to the bicycle sprocket to drive the bicycle. The ratchet teeth [9] of the power synthesis mechanism can be propped up or down according to different operating conditions, and the electric power and manp...

Abstract

The electric bicycle produced in the prior art only realizes the effects of a bicycle and an electric motor, and substantially belongs to a light-duty motor vehicle. The invention combines a harmonic wave speed reduction motor and a double-overrun clutch power coupling mechanism, and then installs the harmonic wave speed reduction motor and the double-overrun clutch power coupling mechanism in a five-way valve of a bicycle, the bicycle is driven to run by a bicycle chain and a mechanical speed-change mechanism, and high efficiency and low energy consumption of the system are ensured. The safety and the convenience of the electric bicycle are completely the same as those of a traditional bicycle. Because of low cost and low energy consumption, the invention can replace the traditional bicycle to become an updating and upgrading product of the bicycle.

Description

Technical field [0001] The invention relates to a harmonic deceleration electric bicycle. Background technique [0002] my country’s electric vehicle market mistakes the simple “bicycle + motor” for light-duty vehicles as “electric bicycles” because of their unreasonable design, unsafe, heavy, high energy consumption, and high cost. They are not a mature product at all. It is that the product does not comply with the new "Traffic Law" on May 1, 2004 for non-motorized vehicles (electric bicycles) regulations. At present, many cities in my country have banned such electric vehicles from driving, and such electric vehicles will soon be marketed. Completely eliminated. Summary of the invention [0003] The technical scheme adopted by the present invention is: after the harmonic deceleration motor is combined with the double overrunning clutch power synthesis mechanism, it is installed in the bicycle bottom bracket, and the bicycle is driven through the bicycle chain and the mechanical ...
