行星齒輪機構廣泛地應用於各式車輛自動變速器，藉離合器與制動器控制行星齒輪機構的固定構件與輸入構件達到變換不同轉速比的目的，為使一行星齒輪機構能夠提供更多的速檔，常見的設計便是於行星齒輪機構中置入兩個或三個內嵌離合器，其中對於存在一個內嵌式離合器的設計與研究卻一直被忽略。故本研究主要目的在於針對具一個內嵌離合器之車輛自動變速器，建立一套可行的系統化設計方法。首先，歸納行星齒輪式自動變速器的需求訂定設計規格；其次以現有的二排式行星齒輪機構為基礎，以一簡單程序置入一個內嵌離合器，並建立對應的構想圖集；接著發展檔位合成方法以進行自動變速器之檔位合成；最後發展離合器與制動器配置方法，並對完成配置的自動變速器進行齒數設計，透過性能分析評估所設計自動變速器是否滿足所訂定的規格。本研究成果為完成五顆五速二排式自動變速器、一顆七速三排式行星齒輪機構自動變速器，其各檔效率皆高於0.95，為可行的設計結果。

The epicyclic gear mechanisms are widely used in the automatic transmissions for automobiles, and can provide several speed ratios by the controls of the input and fixed links with clutches and brakes. In order to increase the number of speed ratios, two or three embedded clutches are adapted in the automatic transmissions. However, the design of automatic transmissions with one embedded clutch has been hitherto ignored. Thus, the purpose of this work is to develop a systematic methodology for the design of automobiles automatic transmissions with one embedded clutch. First, the design specifications are established based on the requirements of the epicyclic automatic transmissions. Next, a procedure of the conceptual synthesis is developed to enumerate the epicyclic gear mechanisms with one embedded clutch. The corresponding atlas of the epicyclic gear mechanisms with two fundamental geared entities are established. Finally, a method is created to arrange the clutches and brakes into epicyclic gear mechanisms. Then the numbers of the teeth of gears are calculated by an analytical way. The result of this research shows that five five-speed automatic transmission and one seven-speed automatic transmission are synthesized. The associated efficiency for each speed is greater than 95%. This demonstrates the feasibility of the proposed methodology.
