internal transmission control mechanism

Abstract

The invention discloses an inner transmission control mechanism used in a chainless drive vehicle and a chain drive vehicle. According to the inner transmission control mechanism, a clutch mechanism to be controlled is driven to perform disengage or engage action by a power rotating part (such as an input ring, an inner gear, a planet carrier and an output ring) in an inner transmission via a cam or cam-like structure, or a linkage device is driven by the cam or cam-like structure to rotate or translate so as to enable the clutch mechanism to be controlled to perform disengage or engage action, then a rapid switching effect of the control mechanism is completed by rotating the cam or cam-like structure or the linkage device for a certain angle, main transmission power is supplied by the power rotating part instead of a shifting rod for controlling the switching action, the shifting rod can act relatively slightly, the transmission operation can be relatively accurate, the overall control mechanism is relatively simple and easy, the weight can be relatively reduced, the size can be relatively reduced, and furthermore the overall industrial practicability and the practicable performance of the inner transmission can be improved.

Description

technical field [0001] The present invention relates to an internal transmission control mechanism commonly used in chainless transmission bicycles and chain transmission bicycles, especially the control mechanism is composed of power rotating parts in the internal transmission (such as: input ring, internal gear, planet carrier, output ring, etc.) Use a cam or cam-like structure to drive the action of the clutch mechanism that needs to be controlled by the clutch, or use a cam or cam-like structure to drive a linkage device to rotate or translate to achieve the action of the clutch mechanism that needs to be controlled by the clutch, so as to achieve a cam structure or a cam-like structure The fast switching effect of the control mechanism is achieved when the structure or the linkage device rotates at a certain angle, and the main shifting power comes from the power rotating part, rather than the lever that controls the switching action. Background technique [0002] It is...

AI Technical Summary

Problems solved by technology

[0002] It is generally known that the control mechanism of the internal transmission of the bicycle is not only complicated in structure, but also has the problems of large structure, heavy weight, and high cost, and also causes the sensitivity and speed of the transmission to be unsatisfactory when actually operating the transmission. The shortcomings also directly lead to the reduction of the quality of the internal derailleur and the overall bicycle. Therefore, in the structural design of the relevant bicycle internal derailleur, the industry is constantly striving for innovation and breakthroughs.
