摘 要

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。本文之主要目的為以組合式內變速器之概念,發展一套有效的組合式內變速器的設計理論與方法,希望建立一系統化的設計程序,以利於多速內變速器的創新與開發。首先歸納組合式多速內變速器之基本特性與需求,有系統的合成出適用於組合式多速內變速器的行星齒輪系構型目錄;其次對每一個構型進行檔位合成,確定其檔位作動順序表;接著依照給定之轉速比值配合檔位作動順序表求出齒輪系之齒數;然後對各個可行之機構構型進行調速系統之設計與配置,再依不同的調速系統解繪出其實體圖;最後依性能分析理論進行傳動性能分析與評估,得到較佳之設計以幫助組合式多速內變速器之創新設計與開發。

Abstract
英文摘要

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 by using a concept of combination. First, identify the basic characteristics and design requirement of combinative multi-speed drive hub. Second, using three combinative 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, a computer programs developed for the automatic analysis the transmission performance of drive hubs. The results of this work will be benefit to the development and design of multi-speed bicycle drive hubs.
