什么原因会导致自动变速箱油变质?

发布日期: 2021-04-06 来源: / 点击:

1.自动变速箱温度过高

1. The temperature of automatic transmission is too high
自动变速箱使用时间长(一般为两年或六万公里)不更换,油液就会变质;或者是液力变矩器锁止功能失效;或者是自动变速箱散热器堵塞或散热有个弯曲,都会使自动变速箱温度过高。
If the automatic transmission is not replaced for a long time (generally two years or 60000 km), the oil will deteriorate; or the locking function of the hydraulic torque converter will fail; or the radiator of the automatic transmission is blocked or bent, which will cause the temperature of the automatic transmission to be too high.
2.自动变速箱进水(变速箱进水后油液会出现乳状)
2. Water in the automatic transmission (the oil will appear emulsion after water in the transmission)
自动变进水一般有两种情况,种:发动机冷却液通过散热器进入自动变速箱;第二种:雨水或洗车水从自动变速箱透气孔进入。自动变速箱进水后,车辆故障并不会在时间显示,因此车主要实时对变速箱油进行观察。
Generally, there are two kinds of water entering the automatic transmission: the first is that the engine coolant enters the automatic transmission through the radiator; the second is that the rainwater or car washing water enters the automatic transmission through the vent. After the automatic transmission is flooded, the vehicle fault will not be displayed at the first time, so the vehicle mainly observes the transmission oil in real time.
3.油面高度差误大
3. The height difference of oil level is large
油位过低,油泵将吸入空气,使油液与空气混合;油位过高,会使行星齿轮和其他旋转部分浸在变速箱中,发生搅动油液现象。无论是过高或过低,都会导致自动变速箱油变质,从而出现故障。
If the oil level is too low, the oil pump will take in air to mix the oil with the air; if the oil level is too high, the planetary gear and other rotating parts will be immersed in the transmission and the oil will be agitated. Whether it is too high or too low, will lead to automatic transmission oil deterioration, resulting in failure.
4.摩擦片打滑
4. Friction plate slipping
离合器、制动器的摩擦元件打滑也会引起变速箱油的变质,这种现象会导致发动机转速很高,但车速上升缓慢的故障,往往换挡也会受影响。
The sliding of friction elements of clutch and brake will also cause the deterioration of transmission oil. This phenomenon will lead to high engine speed, but the fault of slow speed rise will often affect the shift.
5.金属零件磨损严重
5. Serious wear of metal parts
变速箱油液中存在大量的金属碎末,主要是由于变速箱内的金属零件磨损严重,如变速箱内的中间轴、轴承、离合器钢片、离合器盅等等。
There are a lot of metal debris in the gearbox oil, which is mainly due to the serious wear of metal parts in the gearbox, such as the intermediate shaft, bearing, clutch steel plate, clutch cup and so on.
6.摩擦材料脱落
6. Friction material falling off
这种现象大多出现在自动变速箱进水后但未进行解体大修,而只是更换变速箱油后继续使用。在使用过程中往往会出现摩擦片脱落的现象。
This phenomenon mostly occurs after the automatic transmission is flooded, but it is not disassembled and overhauled, and it is only used after changing the transmission oil. In the process of use, the friction plate often falls off.
