【正文】 ical progress, cars have bee the mainstream of the world, the invention of cars brings mankind great convenience, the handling and fort has also been gradually improving, and the manual transmission has been gradually replaced by automatic transmission. Automatic transmission can be repeated for the acceleration, deceleration, speed transmission, and other functions, the speed with smooth, light and other advantages of driving. But paned with the traditional manual transmission, there are issues such as plex structures, detection, diagnosis and difficult maintenance,so this study is on monvehicle automatic transmission failure . This paper discusses the development of the automatic transmission, automatic transmission and the position, structure, character, principle research. This was followed by the automatic transmission to detect mon fault diagnosis, the main vehicle can not be closed, slipping automatic transmission, automatic transmission abnormal sound. Fault specific description of the phenomenon and possible cause of the malfunction, a detailed analysis of the failure mechanism, automatic transmission and dynamic performance tests use them, stall and delay test pilot, the fault diagnosis to detect and accurately determine fault location. Then the failure to rule out the possibility, and to draw fault diagnosis flow chart. Finally, the scene to collect the actual case analysis to prove that the fault detection accuracy of diagnosis and analysis. 進(jìn)而對(duì)故障進(jìn)行排除，并畫(huà)出故障診斷流程圖。其次對(duì)自動(dòng)變速器常見(jiàn)故障進(jìn)行檢測(cè)診斷研究，主要有汽車(chē)不能行駛、自動(dòng)變速器打滑、自動(dòng)變速器異響。但是與傳統(tǒng)的手動(dòng)變速器相比，也存在結(jié)構(gòu)復(fù)雜、檢測(cè)、診斷和維修難等問(wèn)題，所以本文針對(duì)汽車(chē)自動(dòng)變速器常見(jiàn)故障進(jìn)行研究。摘 要隨著科學(xué)技術(shù)的進(jìn)步，汽車(chē)已經(jīng)成為當(dāng)今世界的主流，汽車(chē)的發(fā)明給人類(lèi)帶來(lái)極大的方便，汽車(chē)的操縱性、舒適性也一直在逐漸提高，而手動(dòng)變速器已經(jīng)逐漸被自動(dòng)變速器所取代。自動(dòng)變速器能進(jìn)行反復(fù)的加速、減速、變速換檔等功能，具有變速平滑、駕駛輕便等優(yōu)點(diǎn)。本文首先論述了自動(dòng)變速器的發(fā)展情況，然后對(duì)自動(dòng)變速器組成、結(jié)構(gòu)、特點(diǎn)、工作原理進(jìn)行研究。描述故障具體現(xiàn)象和可能的故障原因，進(jìn)行詳細(xì)的故障機(jī)理分析，并將自動(dòng)變速器動(dòng)態(tài)性能試驗(yàn)運(yùn)用其中，有失速試驗(yàn)和時(shí)滯試驗(yàn)，對(duì)故障進(jìn)行檢測(cè)診斷，準(zhǔn)確確定故障部位。最后通過(guò)現(xiàn)場(chǎng)收集實(shí)際案例進(jìn)行分析，證明故障檢測(cè)診斷分析的正確性。Key words: automatic transmission。 mon fault。中國(guó)的汽車(chē)工業(yè)雖然起步較晚，但從進(jìn)入20世紀(jì)90年代以來(lái)，民族汽車(chē)工業(yè)沿著合資引進(jìn)與獨(dú)立開(kāi)發(fā)相結(jié)合的道路。隨著城市車(chē)輛密度的加大，自動(dòng)變速器已逐漸成為汽車(chē)的必備裝備，而不僅僅是豪華的標(biāo)志。早在1908 年, 福特 T 型車(chē)最早采用一種兩個(gè)速比的自動(dòng)變速器。從那以后, 自動(dòng)變速器的構(gòu)造原理并無(wú)大的改變, 但材料技術(shù)的進(jìn)步與潤(rùn)滑油性能的提高, 使這種變速器的速度比更為豐富。傳統(tǒng)的離合器由一個(gè)渦輪轉(zhuǎn)換器所取代。轉(zhuǎn)輪式自動(dòng)變速器存在一個(gè)缺點(diǎn), 即起步加速時(shí)令人有一種車(chē)輪打滑的感覺(jué), 于是駕車(chē)人會(huì)猛加油門(mén), 但車(chē)速又并不隨即增高。隨著發(fā)動(dòng)機(jī)燃油噴射與點(diǎn)火裝置的不斷完善, 自動(dòng)變速器也有新的花樣, 如設(shè)置了 “運(yùn)動(dòng)式” 或 “雪地行駛” 等不同的操控方式, 有的在儀表盤(pán)上設(shè)有一個(gè)印有 S 字母的按鈕, 可以在加速時(shí)變得格外迅捷。 更有甚者, 新一代 “隨機(jī)應(yīng)變式” 變速器還可以順應(yīng)駕車(chē)者不
