自动变速箱进水的应急处理方式

发布日期: 2020-08-20 来源: http://www.jnbsx.com/ 点击: 0

1、轻度进水:变速箱里部分螺丝生锈

1. Mild water ingress: some screws in the gearbox are rusty
如果用以上两种做法都无法判断,则需要通过拆解观察变速箱里面的螺丝。因为油和水混合之后,会腐蚀钢性材质的螺丝,如果变速箱疑似进水以后发现有部分螺丝生锈,则可以判断是变速箱轻度进水,且含水量不会太大。
If the above two methods are unable to judge, it is necessary to observe the screws inside the gearbox by dismantling. Because the mixture of oil and water will corrode the screws made of steel material. If the gearbox is suspected of water ingress and some screws are found to be rusty, it can be judged that the gearbox is slightly watered and the water content is not too large.
维修方式:
Maintenance mode:
更换变速箱油和差速油。轻微进水的维修办法与中度进水类似,但主要是以预防为主。更换胶圈、油封、摩擦片等部件,以延长使用寿命,并建议更换变速箱油和差速油。自动变速箱专修
Change the transmission oil and differential oil. The maintenance method of slight water inflow is similar to that of moderate water inflow, but the main method is prevention. The rubber ring, oil seal, friction plate and other parts should be replaced to prolong the service life. It is suggested to replace the transmission oil and differential oil. Special repair of automatic transmission
2、中度进水:油底壳出现白色沉淀物
2. Moderate water inflow: white sediment appears in the oil pan
如果通过放油无法确定是否进水,这时候需要做进一步的检查。具体做法是把油底壳拆卸下来进行观察。因为如果变速箱进水,油和水混合之后会产生一种白色的乳合物,并附着在油底壳上,如果观察到有这种沉淀物,那么变速箱就已经属于中度进水。

If it is impossible to determine whether there is water inflow through oil drainage, further inspection is required at this time. The specific method is to remove the oil pan for observation. Because if there is water in the gearbox, the mixture of oil and water will produce a white emulsion compound, which will adhere to the oil pan. If this kind of sediment is observed, the gearbox is already in the category of moderate water inflow.
维修方式:摩擦片、油封等部件必须更换。中度进水比严重进水需要更换的部件要少很多,但是胶圈、油封、摩擦片等部件,以及变速箱油和差速油都必须彻底更换。如果自动挡多功能开关等元件涉水也需要更换。
Maintenance method: friction plate, oil seal and other parts must be replaced. Moderate water inflow is much less than severe water inflow, but rubber ring, oil seal, friction plate and other components, as well as transmission oil and differential oil must be completely replaced. If the automatic multi-function switch and other components wade in water, they also need to be replaced.

3、严重进水:观察油水混合物即可辨别
3. Serious water inflow: it can be identified by observing the oil-water mixture
变速箱进水比较严重的,可以通过放油直接观察。具体做法是把变速箱里的油排出来,如果进水较多观察油水混合物的颜色和黏稠程度就能判断。
If the water in the gearbox is serious, it can be observed directly by draining the oil. The specific method is to drain the oil in the gearbox. If there is more water in, the color and viscosity of the oil-water mixture can be judged.
维修方式:少三项需要更换。
Maintenance method: at least three items need to be replaced.
(1)要更换胶圈、油封一类的橡胶性质的元件;
(1) To replace rubber ring, oil seal and other rubber components;
(2)要更换摩擦片,因为摩擦片由钢片和高密度的木脂材料组成,遇水发胀后会影响摩擦效果;
(2) It is necessary to replace the friction plate, because the friction plate is composed of steel plate and high-density wood grease material, which will affect the friction effect after swelling in water;
(3)还需要彻底更换变速箱油和差速油;
(3) The transmission oil and differential oil need to be completely replaced;
(4)进水严重时需要更换链轮;
(4) The sprocket wheel needs to be replaced in case of serious water inflow;
(5)是否更换变速箱的阀体要视情况而定,因为如果变速箱进水润滑效果就会减弱;
(5) Whether or not to replace the valve body of the gearbox depends on the situation, because if the gearbox is filled with water, the lubrication effect will be weakened;
(6)如果自动挡多功能开关等元件涉水也必须更换。济南自动变速箱维修
(6) If the automatic multi-function switch and other components wade in water, they must also be replaced. Jinan automatic transmission maintenance
