自動變速箱打滑是自動變速箱的常見故障之一。而自動變速箱漏油是造成自動變速箱打滑的前期原因。
Slip of automatic transmission is one of the common faults of automatic transmission. The oil leakage of the automatic transmission is the early cause of the slip of the automatic transmission.
液壓控制系統(tǒng)的各連接部位上都有油封和密封墊，這些部件是常發(fā)生漏油的地方。液壓系統(tǒng)漏油會引起油路壓力下降，而油位下降則會引起自動變速箱打滑，自動變速器易發(fā)生漏油部位，應逐一進行檢查。
There are oil seals and gaskets on the connecting parts of the hydraulic control system. These parts often leak oil. Oil leakage of hydraulic system will cause the pressure drop of oil circuit, and the drop of oil level will cause the automatic transmission to slip. The parts of automatic transmission prone to oil leakage should be inspected one by one.
總結(jié)來說造成自動變速箱打滑有以下七個原因。
In summary, there are seven reasons for automatic transmission slip.
1.自動變速箱油面太低
1. The oil level of automatic transmission is too low
2.自動變速箱油面過高，運轉(zhuǎn)中被行星排劇烈攪動后產(chǎn)生大量氣泡
2. The oil level of automatic transmission is too high, and a large number of bubbles are produced after being stirred by planetary row during operation
3.離合器或制動器摩擦片、制動帶磨損過甚或燒焦
3. The clutch or brake friction plate and brake belt are worn or even burnt
4.油泵磨損過甚或主油路泄露，造成油路油壓過低
4. The oil pump is worn or even the main oil circuit leaks, resulting in low oil pressure
5.單向超越離合器打滑
5. One way overrunning clutch slips
6.離合器或制動器活塞密封圈損壞，導致漏油
6. The sealing ring of clutch or brake piston is damaged, resulting in oil leakage
7.減振器活塞密封圈損壞，導致漏油
7. The seal ring of shock absorber piston is damaged, resulting in oil leakage
自動變速箱打滑故障，總的來說，都可以通過自動變速箱油位與品質(zhì)來分辨。如自動變速箱油位過低，但無雜質(zhì)，則查找漏油處進行修復故障基本可排除；如自動變速箱油位過高，無雜質(zhì)，調(diào)整自動變速箱油位，故障基本可排除；如自動變速箱油呈棕黑色或有燒焦味，則應拆解變速箱，排查是否內(nèi)部零件（摩擦片、制動帶等）存在磨損。
Generally speaking, the slip fault of automatic transmission can be distinguished by the oil level and quality of automatic transmission. If the oil level of automatic transmission is too low, but there are no impurities, the oil leakage shall be found for repair, and the fault can be basically eliminated; if the oil level of automatic transmission is too high without impurities, the fault can be basically eliminated by adjusting the oil level of automatic transmission; if the oil of automatic transmission is brown black or burnt, the gearbox shall be disassembled to check whether the internal parts (friction plate, brake belt, etc.) are worn.
