Abstract

The invention provides a variable-speed actuating mechanism, a bicycle transmission and a control method, which are applied to the bicycle transmission and comprise a steering engine, a hollow bracket and a winch fixed with a variable-speed cable, wherein The hollow bracket sleeves one end, where an output shaft is located, of the steering engine; the output shaft penetrates through the hollow support and then is connected with the winch, so that the winch is driven to rotate through the output shaft of the steering engine, a speed change line fixed on the winch is tensioned or loosened, and electronic speed change is achieved. The whole device is low in cost and suitable for a bicycle with a modified traditional mechanical speed control system, and the application range is large.

Description

technical field [0001] The application belongs to the technical field of bicycle transmissions, and in particular relates to a transmission actuator, a bicycle transmission and a control method. Background technique [0002] The traditional mechanical shifting system performs shifting operations through various mechanical structures such as gears, ratchets, and winches in the shifting operating mechanism. With the increase of bicycle gears, the mechanical structure of mechanical shifting becomes complicated and heavy, which brings reliability. At the same time, due to the multi-turn winding of the transmission line, the mechanical transmission may also have the problem of fatigue fracture of the transmission line. [0003] At present, some manufacturers adopt electronic transmission system, remove the transmission line of the traditional transmission mechanical system, and directly use the electronic control unit to replace the complicated mechanical structure. However, the ...
