Problems solved by technology

[0004] The said invention patent "A Pedal Torque Sensing System for Electric Power-assisted Bicycles" is not concentrated due to the dispersion of the transmission mechanism, resulting in the complexity of the transmission mechanism, and the frame structure must be specially designed to adapt to the installation position of the high-speed power-assisted motor, resulting in The universality of the frame is poor, the manufacturing cost increases, and the appearance of the whole vehicle is not beautiful

Embodiment Construction

[0024] Now in conjunction with accompanying drawing technical scheme of the present invention is described further:

[0025] In the present invention, the central transmission device of the pedal electric power-assisted bicycle without manual speed regulation integrates the pedal transmission mechanism, the motor transmission mechanism and the pedal torque sensing mechanism as a whole, such as figure 1 , figure 2 shown.

[0026] The main body of the present invention is a hollow-shaft high-speed booster motor 1. The output shaft 4 of the hollow-shaft high-speed booster motor 1 is a hollow structure. The motor transmission mechanism is mainly composed of an output shaft 4, a motor planetary gear reducer and a sprocket shaft 2. Shaped sprocket shaft 2 is installed in the output shaft 4 through bearings, and the end of the sprocket shaft 2 protruding from the output end of the output shaft 4 is the installation position of the chain disc, and the planetary gear reducer of the m...

Abstract

The invention discloses a built-in transmission device of a pedal electric power-assisted bicycle without manual speed regulation. The device comprises a pedal transmission mechanism, a motor transmission mechanism and a pedal moment induction mechanism. The motor transmission mechanism comprises a hollow output shaft of a hollow-shaft high-speed power-assisted motor, a motor planet wheel decelerator and a sprocket wheel shaft. The pedal transmission mechanism comprises a pedal central shaft, a central shaft planet wheel decelerator and a sprocket wheel shaft. The sprocket wheel shaft is rotatably arranged in the output shaft. The pedal central shaft is rotatably arranged in the shaft sleeve of the sprocket wheel shaft. The motor planet wheel decelerator is arranged at one side of the output shaft of the hollow-shaft high-speed power-assisted motor. The central shaft planet wheel decelerator is arranged at the other side of the hollow-shaft high-speed power-assisted motor. The device disclosed by the invention has the characteristics of being concise and intensive in structure, good and reliable in performance, good in process and the like. A motor power-assisted system and physical drive are organically linked but cannot be interfered with each other. The transmission efficiency is very high.

Description

(1) Technical field: [0001] The invention relates to a transmission mechanism of an electric bicycle, in particular to a mid-mounted transmission device for a pedal electric power-assisted bicycle without manual speed regulation. (two) background technology: [0002] The development of the bicycle has gone through the process of pedal bicycle-electric bicycle-pedal electric bicycle-electric power-assisted pedal bicycle. As the latest achievement, the electric power-assisted pedal bicycle is actually a bicycle with pedals as the main pedal, and the motor is used as an auxiliary power-assisted drive. The consumption is exactly the same as that of ordinary bicycles. In the state of electric power assist, when riding, the motor only responds to the pedal stress signal to provide corresponding power assistance, thereby reducing the physical energy consumption of the rider. [0003] In order to prevent the resistance generated by cutting the magnetic lines of force, the motor use...
