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自行車內變速器之系統化設計理論。首先經由分析現有專利歸納出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與配置；最後針對各種可行之設計構想進行評估與分級，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, analyse multi-speed drive hub patents to identify the basic characteristics and design requirement of multi-speed drive hub. Second, using a systematized mathod to synthesize the feasible 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, design and dispose governors of multi-speed drive hubs. The results of this work will be benefit to the development and design of multi-speed bicycle drive hubs.
