技術說明

本發明之目的在於提供一種應用在腳踏車的無段變速裝置。此變速器固定在腳踏車機架上，變速器輸入軸即為腳踏車的踏板軸。變速器以凸輪機構為基礎，具有構造簡單、可靠度高、以及成本低等優點。此變速器可在運動中適時調整傳動速度比，解決習知技術無法同時兼具可靠度高、成本低、以及可以無段變速之問題。本發明主要由主傳動機構、輸出機構(單向離合器)和調速機構所組成，主傳動機構係以一個擺動凸輪機構組成一個相位，由至少三個相位組合成為一個變速機構，經由單向離合器的作用輸出單向的動力，並利用改變偏心凸輪的作用位置達成無段變速的功能。 The purpose of the invention is to provide a continuously variable transmission for application in a bicycle. This transmission is fixed to the bike frame and the transmission input shaft is the pedal shaft of the bike. The transmission is based on cam mechanism and has the advantages of simple construction, high reliability and low cost. This transmission can adjust the transmission speed ratio in motion, and its can solve the problem that know technology cannot combine high reliability, low cost, and stepless speed change. This invention mainly consists of the main drive unit, the output unit and the speed adjusting unit. The main drive unit is formed into a phase by a swing cam mechanism. Consisting of at least three phases to form a continuously variable speed transmission. This transmission output of the power of one direction through the action of a one-way clutch and use to change the eccentric cam's action position to achieve the function of stepless variable speed.
