自动变速箱进水了会出出现哪几种情况?

发布日期: 2021-12-01 来源: http://www.jnbsx.com/ 点击:

情况一:会车时水浪进入变速箱
Case 1: water waves enter the gearbox when meeting
二种情况是在会车时,如果路面积水过多,那么激起的浪花打在车身上,也有可能导致变速箱进水。
In the second case, if there is too much water in the road area during the meeting, the generated waves will hit the body, which may also lead to water in the transmission.
情况二:水没过车轮2/3以上
Case 2: the water is more than 2 / 3 below the wheel
二种情况是汽车进水。具体判断标准是如果水没过车轮的2/3以上,那么变速箱进水的概率就会很高,如果水已经没过仪表台的位置,那么变速箱就已经进水了。
The second is that the car is flooded. The specific judgment standard is that if the water does not exceed more than 2 / 3 of the wheel, the probability of water ingress into the gearbox will be very high. If the water has not exceeded the position of the instrument panel, the gearbox will have water ingress.
当变速箱进水后,变速箱油的性能会受到严重的影响,不仅仅是润滑性能受损,变速箱油的传递动力的性能也会下降,进而使离合器片出现打滑,随即油温升高,这也会导致水蒸气的产生甚至使油水混合物出现沸腾,这些粘稠的物质还会堆积到阀体内造成阀体的堵塞,从而影响到变速箱的控制系统。在车辆涉水后,如果发现车辆挂挡不走,又或者加油时出现异常的抖动,建议车友们还是尽快联系修理厂进行检修,避免造成更大的损失。
When the transmission is flooded with water, the performance of the transmission oil will be seriously affected, not only the lubrication performance will be damaged, but also the power transmission performance of the transmission oil will be reduced, which will cause the clutch plate to slip, and then the oil temperature will rise, which will also lead to the generation of water vapor and even the boiling of the oil-water mixture, These viscous substances will also accumulate in the valve body, causing blockage of the valve body, thus affecting the control system of the transmission. After the vehicle wades into the water, if it is found that the vehicle does not move in gear, or there is abnormal shaking during refueling, it is recommended that the riders should contact the repair shop for maintenance as soon as possible to avoid greater losses.
变速箱进水分三种程度
There are three levels of transmission water inlet
1、轻度进水:变速箱里部分螺丝生锈
1. Slight 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 you can't judge by the above two methods, you need to disassemble and observe the screws in the gearbox. Because the mixing of oil and water will corrode the screws made of steel. If some screws are rusted after the gearbox is suspected of water ingress, it can be judged that the gearbox is slightly water ingress and the water content will not be too large.
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 through oil drainage, further inspection is required at this time. The specific method is to disassemble the oil pan for observation. Because if the transmission is flooded, a white emulsion will be produced after the oil and water are mixed and attached to the oil pan. If such sediment is observed, the transmission has been moderately flooded.
3、严重进水:观察油水混合物即可辨别
3. Severe 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 through oil drainage. The specific method is to drain the oil in the gearbox. If there is more water, it can be judged by observing the color and viscosity of the oil-water mixture.
针对变速箱不同的进水状态,小编给出以下的维修建议:
According to different water inflow conditions of the gearbox, the minor editor gives the following maintenance suggestions:
1、轻微进水:好更换变速箱油和差速油
1. Slight water ingress: replace the transmission oil and differential oil
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。好更换胶圈、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。
The maintenance method of slight water inflow is similar to that of moderate water inflow, but mainly based on prevention. Replace the rubber ring, oil seal, friction plate and other parts to prolong the service life, and it is recommended to replace the transmission oil and differential oil.
2、中度进水:摩擦片、油封等部件需要更换
2. Moderate water inflow: friction plate, oil seal and other parts need to be replaced
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需要更换。如果自动挡多功能开关等元件涉水也需要更换。
There are many fewer parts to be replaced for moderate water inflow than for severe water inflow, but the rubber ring, oil seal, friction plate and other parts, as well as transmission oil and differential oil need to be replaced. If the automatic multi-function switch and other components Wade, they also need to be replaced.
3、严重进水:至少三项需要更换
3. Serious water inflow: at least three items need to be replaced
进水严重的变速箱需要更换的部件很多,下面列有六个维修项目,其中前三种需要实行:一,要更换胶圈、油封一类的橡胶性质的元件;二,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;三,还需要更换变速箱油和差速油;四,进水严重时需要更换链轮;五,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;六,如果自动挡多功能开关等元件涉水也需要更换。
The gearbox with serious water inflow needs to replace many parts. The following six maintenance items are listed, of which the first three need to be implemented: first, replace rubber components such as rubber rings and oil seals; 2、 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 case of water; 3、 The transmission oil and differential oil also need to be replaced; 4、 Replace the sprocket in case of serious water inflow; 5、 Whether to replace the valve body of the gearbox depends on the situation, because if the gearbox is flooded, the lubrication effect will be weakened; 6、 If the automatic multi-function switch and other components Wade, they also need to be replaced.
特别提醒:修好变速箱还需再清理散热油道把进水的变速箱修好之后,并不意味着一切结束。因为车辆的散热油道依然存在水分,如果直接安装水还会再次进入变速箱。因此,在把变速箱安装上车之前,需要将散热油道的水都全部清掉。
Special reminder: after repairing the gearbox, you also need to clean the cooling oil passage. Repairing the water filled gearbox does not mean that everything is over. Because there is still water in the heat dissipation oil duct of the vehicle, if it is installed directly, the water will enter the transmission again. Therefore, before installing the gearbox on the vehicle, it is necessary to clear all the water in the cooling oil passage.
