中文摘要 |
行星齒輪式自動變速器廣泛的運用於車輛中,行星齒輪式自動變速器具有 構造緻密、體積小、高減速比等優點,藉由更換不同的離合器或制動器可以得到 不同的輸出轉速。對於行星齒輪式自動變速器的專利非常的多,但大部分專利趨 勢趨向於三自由度行星齒輪系或者使用內嵌式離合器制動器等複雜的構型。若能 在同樣多速,相同轉速比的前提下,使用製造和控制上相對簡單的二自由度變速 機構和外部離合器制動器,將會是變速機構比較好的選擇。故本論文提出一套針 對二自由度並排式行星齒輪式自動變速器的設計流程並使用電腦輔助設計。首先 建立可達到八速自動變速器的比例數線圖,拆解比例數線圖所有可能的三點數 線,將四組不同三點數線組合得到所有可能構行,利用直接數碼法得到構件編號 數碼,判斷構型配置制動器離合器的可能。剔除不能配置的構型,建立可配置構 行資料庫,最後給定轉速比,剔除不符合限制範圍基本齒數比的構型,並繪製可 用之構行簡圖。將簡圖依齒數設計利用繪圖軟體實體化。 關鍵詞:行星齒輪式自動變速器、比例圖畫、直接數碼法、構件編號數碼、離合 器配置 |
Abstract |
Epicyclic-type automatic transmissions are used in automobiles widely. There are many advantages of epicyclic-type automatic transmissions. It is composed more densely, smaller and provide higher gear ratio. We can get different output speed by actuating different clutches or brakes. There are a lot of patents for epicyclic-type automatic transmissions, but most of them tends to be three degrees of freedom automatic transmissions or using embedded clutches or brakes and other complex constructions. It is a better choice if we could use relatively simple manufacturing and control of two degrees of freedom and external clutches and brakes in the same multi speeds, speed ratio of the same premise. Therefore, this study aims to propose a set of design process for two degrees of freedom parallel-connected epicyclic gear automatic transmissions and computerize the process. First, we established the lever diagram for eight-speed automatic transmissions. By decomposing lever diagrams to all possible three-point lines, then composing four different lines to get all possible eight-speed automatic transmission constructions. Then, we use direct-member -number method to get member number of all constructions. Determining the possibility of configuring clutches and brakes, excluding the construction which can’t configure the clutch and brake, establish the database can be configured. Finally, we determine a speed ratio for the eight-speed automatic transmissions, excluding the constructions doesn’t match the appropriate gear ratios. Drawing the diagram which comply the restriction for eight-speed automatic transmissions. Keywords: automatic transmission, lever diagram, direct-member-number method, member number, configuration of clutches |
