以行星齒輪系為變速機構主體的自行車內變速器具有體積小、換檔作動穩定與不易受到外在環境影響等優點,故內變速器已逐漸成為各大車廠研發的重點。本文之主要目的在於發展一套設計理論,使自行車內變速器的設計系統化。首先歸納內變速器之基本特性與需求,作為內變速器設計之依據,有系統的建立內變速器的可用行星齒輪系構型目錄;其次對每一可用行星齒輪系構型進行檔位合成,確定其檔位作動表;接著依照給定之轉速比值配合檔位作動表求出齒輪系之齒數;然後進行內變速器調速系統之設計,並建立將變速機構與調速系統結合成一變速器的相關理論;最後進行新型內變速器的探討,尋求可能的新型內變速器,以利於內變速器的創新與開發。
A multi-speed drive hub is one of important components in transmission system. The purpose of this work is to develop a system methodology for the design of multi-speed bicycle drive hubs. First, identify the basic characteristics and design requirement of multi-speed drive hub. Second, using the useful gear trains. Third, a method is proposed to determine the feasible multi-speed sequence tables for each gear train. Fourth, an analytic method is formulated to synthesize the gear ratios and gear teeth according to a set of desired speed ratios. Fifth, the basic theory for transmission analysis of multi-speed drive hubs will be developed. The results of this work will be benefit to the development and design of multi-speed bicycle drive hubs.
