Problems solved by technology

In 1994, Japan’s Yamaha Engine Co., Ltd. launched it to the market. The motor is installed on the central axis of the bicycle. The output speed is reduced to below 60 revolutions per minute through the reducer. The control system processes the signal collected by the torque sensor and synthesizes it with human pedaling. Driven vehicles can be defined as the first generation of electric bicycles, which need to be improved urgently due to their large size, heavy weight, low efficiency and high manufacturing costs.

Embodiment Construction

[0012] The super electric bicycle adopts an engine combined with a harmonic reducer with a large reduction ratio and a high-speed brushless motor, which is more than 50% smaller than an engine of the same power in volume and weight. Drive, expand the inner diameter of the bottom bracket of the bicycle from 40mm to 102mm, and install the engine from the axial direction of the bottom bracket. insert into the inside of the down tube of the bicycle (attached image 3 Shown), because the engine, battery and controller are all hidden inside the body of the bicycle, so the super electric bicycle achieves a stunning visual effect.

[0013] The super electric bicycle engine is composed of a harmonic reducer (attached Figure 4 ) 4-6 output power and manpower (pedaling the bicycle crank) through the double overrunning clutch (attached Figure 4 )4-7 are combined to drive the vehicle together.

[0014] The power output by the engine of the super electric bicycle passes through the pas...

Abstract

The invention relates to a super electric bicycle. A sinusoidal wave driving harmonic gear reducing driving motor technology, a double gear tooth effect power distribution execution technology, a position and current double closed loop control technology and a technology of arranging an engine device in an enlarged bottom bracket of the bicycle and arranging a power source and a control system in a lower pipe of the bicycle are adopted. The unprecedented super electric bicycle is provided, all excellent attributes of bicycles are retained, the super electric bicycle has the advantages of being extremely strong in performances, extremely light and highly dazzling in vision and having extremely long endurance and the like, optimal combination of performance and portability of the electric bicycle is created, and the super electric bicycle is excellent in comprehensive performance and low in manufacturing cost and is bound to replace a manpower bicycle to become the most commonly used tool for riding instead of walk.

Description

Technical field [0001] The invention relates to a super electric bicycle. Background technique [0002] A vehicle with an electric motor installed in a bicycle wheel cannot be defined as an electric bicycle in the strict sense. In 1994, Japan’s Yamaha Engine Co., Ltd. launched it to the market. The motor is installed on the central axis of the bicycle. The output speed is reduced to below 60 revolutions per minute through the reducer. The control system processes the signal collected by the torque sensor and synthesizes it with human pedaling. Driven vehicles can be defined as the first generation of electric bicycles, which need to be improved urgently due to their large size, heavy weight, low efficiency, and high manufacturing costs. Contents of the invention [0003] The purpose of the invention is to improve the comprehensive performance of the electric bicycle. [0004] The technical solution adopted in the present invention is: adopt (1) sine wave drive, harmonic ...
