自动变速箱油变质的原因有哪些?

发布日期: 2021-12-07 来源: http://www.jnbsx.com/ 点击:

1、自动变速箱温度过高:自动变速箱运行时会因为内部元件运动摩擦而产生大量的热量,高温会破坏ATF的质量和摩擦特性,加剧内部元件磨损,ATF会变成褐色或暗红色并发出烧焦的味道,同时油泥/杂质等也会在变速箱内部产生,长期不更换变速箱油,将导致油液变质。

1. The temperature of automatic transmission is too high: when the automatic transmission is running, a large amount of heat will be generated due to the movement and friction of internal components. The high temperature will damage the quality and friction characteristics of ATF and aggravate the wear of internal components. The ATF will turn brown or dark red and give out a burning smell. At the same time, oil sludge / impurities will also be generated inside the transmission. The transmission oil will not be replaced for a long time, This will cause the oil to deteriorate.
2、自动变速箱进水:变速箱进水后油液会出现乳状,一般进水情况有两种,一种:发动机冷却液通过散热器进入自动变速箱;另一种: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,车辆故障并不会立即反映出来,因此车主要定期对变速箱油进行观察。
2. Automatic transmission water inflow: the oil will appear emulsion after the transmission water inflow. Generally, there are two kinds of water inflow conditions: one is that the engine coolant enters the automatic transmission through the radiator; Another: rainwater or car washing water enters from the vent hole of the automatic transmission. After the automatic transmission is flooded with water, the vehicle fault will not be reflected immediately, so the vehicle mainly observes the transmission oil regularly.
3、油面高度差误大:自动变速箱油位的高低,也将影响自动变速箱油的品质,从而出现变速箱故障。油位过低,油泵将吸入空气,使油液与空气混合,这种情况变速箱油会产生大量的泡沫,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。
3. Large oil level difference: the oil level of automatic transmission will also affect the quality of automatic transmission oil, resulting in transmission failure. If the oil level is too low, the oil pump will inhale the air and mix the oil with the air. In this case, the transmission oil will produce a lot of bubbles. The excessive oil level will cause the planetary gear and other rotating parts to be immersed in the gearbox, causing the phenomenon of stirring oil.
4、摩擦片打滑:变速箱内部离合器、制动器的摩擦元件打滑会引起变速箱油的变质,此时变速箱油液往往呈黑色,并伴有焦味。导致发动机转速很高,但车速上升缓慢的故障,换档也会受影响。
4. Slip of friction plate: the slip of friction elements of clutch and brake inside the transmission will cause the deterioration of transmission oil. At this time, the transmission oil is often black with scorching smell. If the engine speed is very high but the vehicle speed rises slowly, the shift will also be affected.
5、金属零件磨损严重:如果变速箱油液中存在大量的金属碎末,这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、离合器钢片等。
5. Serious wear of metal parts: if there is a large amount of metal debris in the transmission oil, this is mainly due to the serious wear of metal parts in the transmission, such as intermediate shaft, bearing, clutch steel plate, etc.
6、摩擦材料脱落:这种现象大多出现在自动变速箱进水后,未进行维修,而只是更换变速箱油后继续使用,造成的摩擦片脱落的现象。
6. Friction material falling off: most of this phenomenon occurs after the automatic transmission is flooded and is not repaired, but only continues to be used after replacing the transmission oil, resulting in the falling off of the friction plate.
