【正文】 如果加速踏板踩到底時(shí)，強(qiáng)制降檔開關(guān)觸點(diǎn)沒有閉合，可用手動(dòng)開關(guān)。 液力變矩器離合器無(wú)鎖止故障的排除 (1)故障現(xiàn)象 汽車行駛中，車速、檔位已經(jīng)滿足離合器鎖止條件，但鎖止離合器仍沒有鎖止作用；油耗增大。 (3)排除方法 對(duì)電控自動(dòng)變速器進(jìn)行故障診斷。 如果倒檔油路油壓正常，應(yīng)拆檢自動(dòng)變速器，更換損壞的離合器或制動(dòng)器摩擦片或制動(dòng)帶。如果不能升人超速檔是因?yàn)槌僦苿?dòng)器打滑，所以在有負(fù)荷情況下不能升人超速檔。在 ON 位時(shí)，超速檔開關(guān)觸點(diǎn)應(yīng)斷開，指示燈不亮；在 OFF 位時(shí)，超速檔開關(guān)觸點(diǎn)應(yīng)閉合，指示燈應(yīng)亮。檢查前進(jìn)檔離合器，如果摩擦片燒損或磨損過度應(yīng)更換。此時(shí)應(yīng)拆檢自動(dòng)變速器，檢查調(diào)速器固定螺釘是否松動(dòng)，調(diào)速器油路密封環(huán)是否損壞，閥芯是否卡滯或磨損過度。檢查、調(diào)整節(jié)氣門拉線或節(jié)氣門位置傳感器，測(cè)量節(jié)氣門位置傳感器電阻，如不符合標(biāo)準(zhǔn)應(yīng)更換。 (2)故障原因 節(jié)氣門拉線或節(jié)氣門位置傳感器調(diào)整不當(dāng)；調(diào)速器存在故障；調(diào)速器油路漏油；車速傳感器故障； 2 檔制動(dòng)器或高檔離合器存在故障；換檔閥卡滯或檔位開關(guān)故障。若在 3 檔時(shí)打滑，原因?yàn)榈箼n及高檔離合器故障。 檢查油壓電磁閥的工作是否正常；檢查電控單元在換檔瞬間是否向油壓電磁閥發(fā)出控制信號(hào)。 (2)故障原因 發(fā)動(dòng)機(jī)怠速過高；節(jié)氣門拉線或節(jié)氣門位置傳感器調(diào)整不當(dāng)，主油路油壓高；升檔過遲；真空式節(jié)氣門閥真空軟管破損；主油路調(diào)壓閥故障，使主油路油壓過高；減振器活塞卡住，不起減振作用；單向閥球漏裝，制動(dòng)器或離合器接合過快；換檔組件打滑；油壓電磁閥故障；電控單元故障。If the control system have no breakdown, then should replace to change the machine of. The can39。2 file pulsory the system moves the machine beats slippery or low file and pour the file system move the machine beats slippery。The control system electric circuit breaks down。At OFF hour, exceed the speed limit the file switch order and should shut to match, instructioning the light should be to exceed the speed limit the file electric circuit or replace to exceed the speed limit the file switch otherwise. The check exceeds the speed limit the work circumstance of the file electromagism to light the fire switch, do not start to launch the machine, press the O/ the switch of D, exceed the speed limit the file electromagism valve should have the coalescence have no the coalescence voice, should check to control the electric circuit or replace the electromagism valve. Use to raise to rise the machine raise the vehicle, making fourwheeler to launch the machine, make the gearbox of auto worked in the file of D, check the automatic gearbox to rise the file circumstance while having no the appearance of can rise the person exceed the speed limit the file, and the car is soon normal, elucidation control system work is can39。Exceeding the speed limit the electromagism valve breaks down。At D hour car can39。Outputting the stalk ascends to adjust soon the machine passes in and out the oil bore seals pletely turn damage。Adjust soon the machine oil road leaks the oil。Clutch or system move the machine seals pletely a damage causes leak the oil。The soft tube in vacuum of the check vacuum type solar division powerful road tries the automatic gearbox in check rises the file whether over late, rise the file over the late is to shift gear the big and familiar reason in impact. The main oil in examination road is dai soon the hour main oil road is hydraulicpneumatic high, explain the main oil road adjust to press valve or solar division powerful families exsits breakdown。The soft tube in vacuum in powerful family in solar division in type in vacuum is damaged。Drive the inside, the automatic gearbox rises the file to produce the vibration in a twinkling. Launch the machine soon over high。The hydraulicpneumatic electromagism valve breaks down。Clutch or system move the machine wears away seriously。Or can rise 2 file, but can39。Check file a switch to adjust soon the machine is hydraulicpneumatic, if the car adjusts after going up soon the machine is hydraulicpneumatic to 0 or very low, explain to adjust soon machine contain breakdown or leak the the control system have no breakdown, should dismantle the automatic gearbox in檢 , the check shifts gear to carry out whether module beat or not slippery, use the pressed air the check each clutch, system move machine oil urn or pistons to has had no to leak. The automatic gearbox in rises the exclusion of the slowmoving breakdown in file (1) break down the phenomenon The car drives the inside, rising the file car soon higher, launch the machine turn soon too higher。Spread to feel the machine break down. (3) expel the method The electricity controls the gearbox of auto should proceed the breakdown , adjust the solar division door pulls wires or the solar division door position spreads to feel machine, measure the solar division a position spreads to feel machine electric resistance, if not agree with the up to standard automatic gearbox of the adoption vacuum type solar division powerful family, should check whether soft tube in vacuum leak air or check declines the file switch pulsory whether short circuit. 河北工程大學(xué)設(shè)計(jì)說(shuō)明書 (論文 ) ]] 7 Measure the soon main oil in road hydraulicpneumatic, if hydraulicpneumatic too high, should pass the solar division door pull wires or the solar division door position spreads to feel the machine gives the automatic gearbox of the adoption vacuum type solar division powerful family, the application reduces the method proceeding adjustment that solar division powerful family push pole the above adjustment is invalid, should dismantle hydraulicpneumatic valve in or solar division powerful families. Measure to adjust soon the machine is hydraulicpneumatic, adjusting soon the machine is hydraulicpneumatic and should go up soon with the car bu
