This car mileage has more than 300000 km, the engine was overhauled, automatic transmission because the oil bottom shell bumps oil also had overhauled. Because of the recent R hanging file, must be banging accelerator can take the car. Once again the automatic gearbox overhaul, replacing worn clutch device after confirmation, torque converter has damaged. The replacement of a renovation of the torque converter, a posite of all running normally。 but after 3 months appeared unable to travel, after inspection, diagnosis for fault of automatic transmission, automatic transmission output power shortage.配備km175系列變速箱一個現(xiàn)代索納塔轎車。這輛車?yán)锍桃殉^300000公里，索納塔汽車大修，自動變速箱由于油底殼油也有凸起的檢修。由于最近的R掛檔，必須用加速器可以把一輛車。再次確認(rèn)后，自動變速箱檢修，更換磨損的離合裝置，液力變矩器已損壞。一個更新的液力變矩器的更換，對所有正常運(yùn)行的復(fù)合；但3個月后出現(xiàn)無法旅行，檢查后，自動變速箱的故障診斷，自動變速箱的輸出功率不足。 變速箱發(fā)熱車輛行駛一段路程后，在行駛途中停車檢查，用手觸摸變速箱殼體各部溫度，如果手能忍受，可認(rèn)為油溫正常；若手不能忍受，則為發(fā)熱故障。過熱行駛會造成齒輪、軸承及其他部件早期磨損，重則使零件燒結(jié)損壞。 變速箱異響變速箱內(nèi)的響聲有良性和惡性兩種。良性響聲多屬于變速箱內(nèi)缺油或潤滑油過稀，軸承磨損后松曠，齒輪磨損后嚙合間隙過大而產(chǎn)生的噪音。齒輪的噪音隨著汽車行駛速度和負(fù)荷變化而變化。而惡性響聲多屬于齒輪上輪齒損壞或齒隙被臟物墊住，發(fā)出間斷而有規(guī)律的沖擊聲。此種故障一旦產(chǎn)生，應(yīng)立即停車檢查，查明原因予以排除。 變速箱怠速不良。該轎車行駛時各方面正常，但是一旦把轎車停下了掛入P檔，索納塔汽車轉(zhuǎn)速就會升至2500r/min左右，無法回到正常的怠速狀態(tài)。同時客戶還反應(yīng)，該車曾因提速緩慢而在其他修理廠做過自動變速箱大修，但自動變速箱維修后，該車的提速有時還是不好8。變速箱掛擋時十分吃力，往往很難掛上擋，勉強(qiáng)掛入某擋時，會產(chǎn)生齒輪撞擊聲。需要退出擋位時，仍然十分困難。 fault detectionThe automatic gearbox off after the discovery, crankshaft and flywheel connected torque converter of a shape similar to the radial plate triangular, all faults in the fixed screw hole, torque converter off, not with the flywheel rotate. The power was cut off, transmission power nature cannot output. The replacement of a radial plate, refitted car. The normal running of the vehicle after 1 months, and on the highway amp。quot。collapseamp。quot。. 自動變速箱起飛后發(fā)現(xiàn)，曲軸和飛輪的形狀類似于徑向板三角形連接的液力變矩器，在固定螺絲孔，所有故障，變矩器，不與飛輪轉(zhuǎn)動。電源被切斷，自然不能輸出功率。一個徑向板更換，改裝車。1個月后車輛的正常運(yùn)行，對公路“崩潰”；。Will the car back to the garage, lift transmission inspection, found a new radial plate to change up and all the fracture, the screw fixed is examined carefully, but did not damage the automatic transmission oil paction and other ponents. Why one after another are radial plate damage caused by fault, fault converter off. 將車開回車庫，電梯傳動檢查，發(fā)現(xiàn)了一個新的徑向板改變了所有的螺絲固定骨折，仔細(xì)的檢查，但沒有損壞自動變速箱油的壓實(shí)和其他部件。為什么一個又一個的都是由斷層引起的徑向板損壞，故障轉(zhuǎn)爐。After careful examination of torque converter, the rear end of the crankshaft part extends into the flywheel shaft neck not normal wear.
