汽車自動變速器為配置於引擎與驅動輪之間的一種傳動裝置，主要提供車輛在增減速時，引擎能維持在一定的工作轉速範圍。已量產的行星齒輪式汽車自動變速器數目雖多，但在相關比例圖畫法之設計理論上尚未完善，故本研究主要目的在於提出一套有效的行星齒輪式汽車自動變速器比例圖畫設計方法。本文首先介紹行星齒輪式汽車自動變速器的基本組成與作動原理，以及行星齒輪機構的構造圖集目錄，並建立行星齒輪式汽車自動變速器之設計規格；其次，介紹比例圖畫法之基本理論，並對現有汽車自動變速器進行分析，另一方面建立二自由度13型七桿與190型九桿行星齒輪機構之可行比例數線圖集目錄；然後，提出比例圖畫法之一般性檔位合成理論，建立四共軸構件與五共軸構件可行檔位作動順序之比例關係限制範圍，並得到可行構型之檔位作動順序與其基本齒數比範圍；最後，應用平面圖畫之離合器配置理論以及比例關係之齒數設計，進行六速自動變速器之設計。本研究結果顯示七桿二自由度行星齒輪機構與九桿二自由度行星齒輪機構確實能提供的最高檔位數分別為四速與六速。

　An automatic transmission that is a transmission device between the engine and drive wheel, offers the vehicle while increasing and decreasing the speed mainly. Its job keeps the engine within a certain working rotational speed range.　Although there are many epicyclic-type automatic transmissions in production, the related design methods of lever diagram is not well developed.　Thus, the purpose of this research is to develop a systematic design of the epicyclic gear transmissions for automobiles with lever diagrammatical methodology.　First, fundamentals and gear-shifting operations of the four-speed and six-speed epicyclic-type automatic transmissions are illustrated to establish the design requirements.　Second, based on the basic theories of lever diagram, a procedure is applied to kinematic analysis for automatic transmission existed, and set up composite lever diagrams of 13 two-DOF seven-link epicyclic gear mechanisms and 190 two-DOF nine-link epicyclic gear mechanisms.　Next, a general clutching-sequence synthesis of lever diagrammatical method are proposed and illustrated. According to the limit range of lever dimensions established for four and five coaxial components, the clutching-sequences and the ranges of basic gear ratio of the feasible gear trains can be derived.　Finally, the planar-graph representation for arranging desired clutch and the number of teeth based on lever dimensions are applied to design six-forward speeds automatic transmission. The result of this work shows that the seven-link two-DOF epicylic gear mechanisms, and the nine-link two-DOF parallel-connected epicylic gear mechanisms could reach four- and six-forward speeds at most, respectively.
