Abstract

The invention provides a three-speed device with parts convenient to replace and capable of providing a high speed ratio, and relates to the field of speed changers. The three-speed device with the parts convenient to replace and capable of providing the high speed ratio comprises a shell body, wherein a transmission rod, a rotating rod I, a rotating rod II are sequentially arranged on the top ofthe shell body from left to right in an interpenetrating mode, and the ends, close to the shell body, of the transmission rod, the rotating rod I and the rotating rod II all penetrate through the topof the shell body and extend into the shell body. According to the three-speed device with the parts convenient to replace and capable of providing the high speed ratio, by arranging a clamping rod, asliding plate, a clamping ring, a tube body, nuts, a spring and a rotating disk, the effect of the convenient replacement of the parts of the three-speed device capable of providing the high speed ratio is achieved, and thus the use of users is facilitated, the working efficiency of the three-speed device capable of providing the high speed ratio is further improved, meanwhile, the use efficiencyof the three-speed device capable of providing the high speed ratio is further improved, and the use of the users is further facilitated.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a three-speed device that can provide large speed ratios and is convenient for replacing parts. Background technique [0002] Bicycle automatic transmission (that is, internal transmission) is a new type of transmission that is designed and manufactured using centrifugal and lever principles, and automatically shifts gears as the riding speed changes. The shift range is more suitable for people's normal riding rules, and the shifting time can be adjusted according to people's preferences. The shifting power is driven by the centrifugal force generated by the bicycle riding state, and it depends on the riding speed. To control the speed ratio, and through the combination of torque input and mechanical principle, the movement driven by centrifugal force is limited, the gear is locked, and the purpose of fixed gear positioning is achieved. [0003] When it comes to the use of...
