情況一：會(huì)車時(shí)水浪進(jìn)入變速箱
Case 1: water waves enter the gearbox when meeting
二種情況是在會(huì)車時(shí)，如果路面積水過(guò)多，那么激起的浪花打在車身上，也有可能導(dǎo)致變速箱進(jìn)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.
情況二：水沒(méi)過(guò)車輪2/3以上
Case 2: the water is more than 2 / 3 below the wheel
二種情況是汽車進(jìn)水。具體判斷標(biāo)準(zhǔn)是如果水沒(méi)過(guò)車輪的2/3以上，那么變速箱進(jìn)水的概率就會(huì)很高，如果水已經(jīng)沒(méi)過(guò)儀表臺(tái)的位置，那么變速箱就已經(jīng)進(jìn)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.
當(dāng)變速箱進(jìn)水后，變速箱油的性能會(huì)受到嚴(yán)重的影響，不僅僅是潤(rùn)滑性能受損，變速箱油的傳遞動(dòng)力的性能也會(huì)下降，進(jìn)而使離合器片出現(xiàn)打滑，隨即油溫升高，這也會(huì)導(dǎo)致水蒸氣的產(chǎn)生甚至使油水混合物出現(xiàn)沸騰，這些粘稠的物質(zhì)還會(huì)堆積到閥體內(nèi)造成閥體的堵塞，從而影響到變速箱的控制系統(tǒng)。在車輛涉水后，如果發(fā)現(xiàn)車輛掛擋不走，又或者加油時(shí)出現(xiàn)異常的抖動(dòng)，建議車友們還是盡快聯(lián)系修理廠進(jìn)行檢修，避免造成更大的損失。
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.
變速箱進(jìn)水分三種程度
There are three levels of transmission water inlet
1、輕度進(jìn)水：變速箱里部分螺絲生銹
1. Slight water ingress: some screws in the gearbox are rusty
如果用以上兩種做法都無(wú)法判斷，則需要通過(guò)拆解觀察變速箱里面的螺絲。因?yàn)橛秃退旌现?，?huì)腐蝕鋼性材質(zhì)的螺絲，如果變速箱疑似進(jìn)水以后發(fā)現(xiàn)有部分螺絲生銹，則可以判斷是變速箱輕度進(jìn)水，且含水量不會(huì)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、中度進(jìn)水：油底殼出現(xiàn)白色沉淀物
2. Moderate water inflow: white sediment appears in the oil pan
如果通過(guò)放油無(wú)法確定是否進(jìn)水，這時(shí)候需要做進(jìn)一步的檢查。具體做法是把油底殼拆卸下來(lái)進(jìn)行觀察。因?yàn)槿绻兯傧溥M(jìn)水，油和水混合之后會(huì)產(chǎn)生一種白色的乳合物，并附著在油底殼上，如果觀察到有這種沉淀物，那么變速箱就已經(jīng)屬于中度進(jìn)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、嚴(yán)重進(jìn)水：觀察油水混合物即可辨別
3. Severe water inflow: it can be identified by observing the oil-water mixture
變速箱進(jìn)水比較嚴(yán)重的，可以通過(guò)放油直接觀察。具體做法是把變速箱里的油排出來(lái)，如果進(jìn)水較多觀察油水混合物的顏色和黏稠程度就能判斷。
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.
針對(duì)變速箱不同的進(jìn)水狀態(tài)，小編給出以下的維修建議：
According to different water inflow conditions of the gearbox, the minor editor gives the following maintenance suggestions:
1、輕微進(jìn)水：好更換變速箱油和差速油
1. Slight water ingress: replace the transmission oil and differential oil
輕微進(jìn)水的維修辦法與中度進(jìn)水類似，但主要是以預(yù)防為主。好更換膠圈、油封、摩擦片等部件，以延長(zhǎng)使用壽命，并建議更換變速箱油和差速油。
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、中度進(jìn)水：摩擦片、油封等部件需要更換
2. Moderate water inflow: friction plate, oil seal and other parts need to be replaced
中度進(jìn)水比嚴(yán)重進(jìn)水需要更換的部件要少很多，但是膠圈、油封、摩擦片等部件，以及變速箱油和差速油都需要更換。如果自動(dòng)擋多功能開(kāi)關(guān)等元件涉水也需要更換。
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、嚴(yán)重進(jìn)水：至少三項(xiàng)需要更換
3. Serious water inflow: at least three items need to be replaced
進(jìn)水嚴(yán)重的變速箱需要更換的部件很多，下面列有六個(gè)維修項(xiàng)目，其中前三種需要實(shí)行：一，要更換膠圈、油封一類的橡膠性質(zhì)的元件；二，要更換摩擦片，因?yàn)槟Σ疗射撈透呙芏鹊哪局牧辖M成，遇水發(fā)脹后會(huì)影響摩擦效果；三，還需要更換變速箱油和差速油；四，進(jìn)水嚴(yán)重時(shí)需要更換鏈輪；五，是否更換變速箱的閥體要視情況而定，因?yàn)槿绻兯傧溥M(jìn)水潤(rùn)滑效果就會(huì)減弱；六，如果自動(dòng)擋多功能開(kāi)關(guān)等元件涉水也需要更換。
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.
特別提醒：修好變速箱還需再清理散熱油道把進(jìn)水的變速箱修好之后，并不意味著一切結(jié)束。因?yàn)檐囕v的散熱油道依然存在水分，如果直接安裝水還會(huì)再次進(jìn)入變速箱。因此，在把變速箱安裝上車之前，需要將散熱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.
