Pedal electric power-assisted bicycle with transmission integration and without manual speed regulation

Abstract

The invention discloses a pedal electric power-assisted bicycle with transmission integration and without manual speed regulation, comprising a frame, wheels, a handlebar, a pedal transmission mechanism and an electric transmission mechanism for driving the wheels, and a pedal torque sensing mechanism, wherein the controller of the pedal torque sensing mechanism is disposed on the handlebar; the pedal transmission mechanism comprises a pedal central shaft, a chain wheel shaft and a central shaft planetary gear speed redactor; the electric transmission mechanism comprises a high-speed power-assisted motor, a chain wheel shaft and a motor planetary gear speed redactor; a chain disc on the chain wheel shaft is connected with the flywheel of the rear wheel via a chain; the pedal transmission mechanism, the electric transmission mechanism and the pedal torque sensing mechanism are intensively formed to be a central transmission mechanism using the high-speed power-assisted motor as a main body; and the triangular support and the rear fork of the frame are connected to the shell of the high-speed power-assisted motor. The pedal electric power-assisted bicycle with transmission integration and without manual speed regulation disclosed by the invention simplifies the structure of transmission mechanism and enables the spatial installation position of transmission mechanism to be reduced and suitable for installation for transmission mechanism on the frame of traditional bicycle; and the pedal electric power-assisted bicycle with transmission integration and without manual speed regulation is good in universality.

Description

(1) Technical field: [0001] The invention relates to a pedal electric power-assisted bicycle, in particular to a transmission-integrated 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 used in the existing elec...

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 versatility of the frame is poor, the manufacturing cost increases, the weight of the whole vehicle is large and the appearance is not beautiful
