摘要

2004年以前所生產的前置引擎前輪驅動( Front engine front drive, FF )自動排檔車輛，在行星齒輪系之聯合傳動器的換檔控制機構中，如油/電控制單元或離合器元件等，因未能獲得良好的換檔控制。故無論車輛在起步或行進間切換檔位的過程中，均會發生不良的異常震動。一般使用自動變速箱的汽車，是利用油壓作用到自動變速箱內的制動帶及離合器等的組件上，使其放鬆或壓緊，以控制行星齒輪機構而達到執行換檔的任務。當車輛起步或行進間換檔，油壓作動到離合器或制動帶等組件時，常因各檔傳輸扭矩的高低變化以及轉速比的滑差關係等，在離合器接合的瞬間皆會產生一振動衝擊及噪音。此振動衝擊及噪音在長期自動變速箱的使用下，將造成離合器殼的破裂或離合器殼與離合器軸間之銲接處的裂損漏油，而嚴重縮短自動變速箱及引擎腳架等的使用壽命，並影響駕駛人及乘客之駕駛與乘坐的舒適性。
本研究針對自動聯合傳動器內離合器元件中的離合器背板做一改善，此改善後的自動聯合傳動器除經自動變速箱測試機台嚴格測試外，又經實車3年20萬公里以上的測試。其結果顯示，此改善後的離合器背板，除有效地解決離合器殼破裂或離合器殼與離合器軸間之銲接處裂損漏油的問題外，又能緩和換檔時離合器接合所產生的衝擊，進而增加自動聯合傳動器的使用壽命且提升駕駛人及乘客之駕駛與乘坐的舒適性。

The front engine front drive (FF) vehicles with automatic transaxles were produced before 2004, their shift control mechanism of transaxles of planetary gear system, such as hydraulic/electronic control unit or components of clutch didn’t have well shift control. So it caused unusual vibration in the shift process when vehicles start moving or driving. The vehicles with automatic transaxles used the oil pressure to release or compress the band assy-trans. and components of clutch to control the planetary gear system in order to achieve the shift task. When vehicles shift during start moving or driving, the oil pressure influence on the components of clutch will produce the vibration and noise which were caused by the torque change and the slip of speed ratio. These vibration phenomenon in the long time use will cause the clutch house or the connect place between clutch house and the clutch shaft broken. Moreover will reduce the life-time of transaxles or engine supporter and affect the drivers’ or the passengers’ comfort.
This study improved the backing plate in the clutch of transaxles, during long time and long distance testing bench and road testing. The results show that the improved transaxles can reduce the vibrations and noise when the clutch operating. It can efficiently solve the problems which occur in clutch house and the connect place between clutch and clutch shaft. Then it also increase the life time of transaxles and promote the comfort of the car driving.
