行星齿轮变速器自动控制系统及自行车花鼓内3速自动变速器
By employing a purely mechanically controlled planetary gear automatic control system in the 3-speed automatic transmission within the bicycle hub, combined with a torque sensor and a centrifugal pawl torque disengagement mechanism, the upshifting and downshifting functions of the bicycle hub-mounted transmission are realized. This solves the problems of difficult disengagement and slippage in existing technologies, and improves the flexibility and reliability of the control system.

AI Technical Summary
Existing planetary gear transmission automatic control systems rely on complex electrical and electronic control systems. Furthermore, the purely mechanical control method of the bicycle hub transmission can only shift up but not down, making it difficult to disengage, especially when riding uphill, where it is easy to lose control of the pedals.
The automatic control system of the planetary gear transmission, which adopts pure mechanical control and combines the function of torque sensor, realizes upshifting and downshifting of the initially set gear. The centrifugal pawl is set on the passive component and combined with torque disengagement mechanism to solve the problem of difficult disengagement.
It enables upshifting and downshifting of the 3-speed automatic transmission inside the bicycle hub at the initial gear setting, solving the problems of difficulty in disengaging and stepping into the wrong position, and improving the control flexibility and reliability of the transmission.
