If water gets into the dry clutch transmission, what is the effect on the car?

It can be seen that this is just a large-aperture dust filter, and there is no waterproof function, and there is a certain chance of water ingress when driving in stagnant water. This vent can also be clearly seen from the inside of the gearbox, and it can be seen that this is just a large-aperture dust net, and there is no waterproof function, and there is a certain chance of water ingress when driving in stagnant water. From the inside of the gearbox, it can also be clearly seen that the ablation of the vent fitting piece, the overheating and deformation of the pressure plate, and other faults, which in turn lead to the driving shaking, frustration, abnormal noise, etc.

Lots of dual-clutch shifting.

There is no problem with ventilation, but once it encounters a large rainy weather, or when the car needs to wade, you need to be more careful, because the dry dual-clutch module has a higher temperature during driving, once wading, there is no problem with the moisture entering the gearbox from the vent to ventilate, but once you encounter a large rainy weather, or when the car needs to wade, you need to be more careful, because the dry dual-clutch module has a higher temperature during driving, once wading, The hole in the gearbox from the air vent is exactly in the middle of the gearbox, and there is a water tank in front of it, so even the rain splashed by the tires cannot get in, unless the rainwater level is higher than this position, so don't worry about this problem at all. But some Volkswagen models are not in the same position.

Compared with the ordinary AT gearbox, the DSG closure is not too strict, because it also involves heat dissipation problems, too much water causes damage to the separation bearing, and all models are also try not to wade in water, if you need to pay attention, the depth of the water should not exceed the tire centerline, not only the protection of the transmission, but also the protection of the engine, if the water enters the engine intake, it may lead to fire extinguishing, and the fire will face overhaul. I'm the owner of a Tiggo 7, I've encountered wading situations, I didn't think about it so much, just drive it normally, no! But the low-speed stutter of the dry dual-clutch is really unpleasant!

I'm the owner of a Tiggo 7, I've encountered wading situations, I didn't think about it so much, just drive it normally, no! The best prevention is not to buy it, pay attention to the car when buying to see if it is a dual clutch.

The impact of water ingress into the gearbox on the car is very large, because once the gearbox is flooded, it will first affect the mechanical parts in it, and may even make these mechanical parts rusty and even affect the safety of the vehicle.

Nowadays, many cars are equipped with a dry dual-clutch transmission. In the end, it's because of the low cost of manufacturing. However, many riders don't know that once the dry dual-clutch transmission gets into the water.

It must be dealt with in time, otherwise, the consequences will be serious. It can be said that it was a shock to see. There are many parts inside the gearbox that can be damaged as long as they come into contact with water.

If it is not repaired in time, it is likely to cause serious over-passing, and the car cannot be driven. Correct judgment of the fault during maintenance can reduce the maintenance cost and solve the problem completely. If there is a gearbox fault, you can pay attention to it, which can help judge the fault and reduce the maintenance cost.

I think this has a very big impact on the car, which will lead to the car's shift frustration, uneven driving, poor power response, slow acceleration, and increased transmission failure rate.

Once wading, moisture enters the inside of the transmission from the vent, which can easily cause the dual-clutch module of the dry clutch transmission to deform when heated, which in turn leads to serious failure.

Do you know the concept of wading?

A dry dual-clutch transmission is an example of an automatic transmission, the wading ability is no different from other general models. The wading ability of a family car depends mainly on the height of the chassis, the location of the engine air intakes.

1) "Vehicle" means motor vehicle and non-motor vehicle.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

Whether it is a dry double-plate or single-plate clutch or wet clutch transmission, it is generally not watery when driving at high speeds in heavy rain. There is no breather valve on the upper cover of the transmission, and if the dust jacket between the gear lever and the transmission is damaged, the water splashed on the upper cover of the transmission by high-speed tires will enter the transmission through the damaged dust jacket. If the cap on the transmission cover is damaged or the breather valve is lost, water will splash into the breather valve and enter the transmission at high speeds.

Although you can rest assured that the gearbox will not enter the water, the gearbox is gasketed when the manufacturer designs and manufactures, and it is also very dustproof.

Water ingress into the clutch will cause less friction and less torque transmission, which may not have much impact on driving in the short term, but may damage the clutch trio over time. While the car is moving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine from the gearbox to cut off or transmit the power input from the engine to the transmission.

The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. During the driving of the car, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine from the gearbox to cut off or transmit the power of the engine to the transmission and guess the momentum.

The clutch is a common component in mechanical transmissions, allowing the transmission system to be disengaged or engaged at any time. The basic requirements are: smooth jointing, rapid and thorough separation; Easy to adjust and repair; Small overall dimensions; Small mass; Good wear resistance and sufficient heat dissipation capacity; The operation is convenient and labor-saving, and it is commonly used in two categories: tooth inlay and friction type.

The clutch is installed between the engine and the transmission, and is the assembly that is directly connected to the engine in the drive train of the car.

When the dual-clutch gearbox wades in the water, you must pay attention to the braking distance, that is, the braking distance, if the water is in, the braking distance will become longer, which will affect safe driving. The gearbox will get water after wading because the gearbox has exhaust holes, and the exhaust holes are very low, and the water can easily enter the gearbox through the exhaust holes, which will make the bearings bad.

First of all, when passing over a deep waterlogged pavement, be sure to carefully observe the water accumulation on the pavement. Including the depth of the stagnant water, the flow rate of the stagnant water, the direction of the stagnant water, etc., to determine whether it can be safely passed. If the car wades in the water, if the engine does not turn off, try to stabilize the throttle to avoid back and forth shifts, if the engine is turned off, do not start the engine again, in the case of ensuring personal safety, contact the repair shop for rescue.

When wading in the water with a dual-clutch gearbox, be sure to check the depth of the water before wading, and don't think that other cars can pass you. If you force wading in water, water enters the clutch and causes damage to the dual clutch, and you need to replace the dual clutch assembly as well as the dual mass flywheel, which is quite expensive.

In addition to the dry dual-clutch can not wade in the water, what are the precautions, the dual-clutch car mainly understands.

1. If it is clear water entering: after opening the bottom of the gearbox and pouring out the water and oil, adding new gear oil, driving or running after entering the water, the oil and water will emulsify, and the oil and water are difficult to separate, and the gearbox needs to be removed and opened for cleaning; 2. If there is dirty water or sediment water: if the sediment enters the bearing, then all parts in the gearbox should be removed and cleaned.

When the gearbox is flooded, the performance of the gearbox oil will be seriously affected, not only the lubrication performance is damaged, but the performance of the transmission power of the gearbox oil will also decrease, and then the clutch plate will slip, and then the oil temperature will rise, which will also lead to the generation of water vapor and even make the oil-water mixture boil, and these viscous substances will also accumulate in the valve body to cause blockage of the valve body, thereby affecting the control system of the gearbox.

A gearbox is a device that changes the speed of a car and consists of many gears of different diameters and sizes. The gearbox is mainly used to change the torque and speed of the engine crankshaft to meet the needs of different driving requirements for wheel traction and speed under different driving conditions such as starting, accelerating, driving and overcoming various road obstacles.

The gearbox will produce a certain amount of gas in the process of working, and a large amount of gas will accumulate after the internal pressure rises, such an environment is obviously not conducive to the work of the gearbox, in order to solve this problem, the engineer set up a vent hole at the gearbox housing, fundamentally speaking, this vent is actually a one-way valve, just like the pressure relief valve on the pressure cooker, under normal circumstances, the valve is closed, and when the internal pressure is on, the check valve will be opened for pressure relief.

Therefore, from the point of view of the design structure, the gearbox is not very prone to water ingress. However, if the valve is stuck by a foreign object and cannot be returned to the closed state, when the water does not reach the top of the gearbox, the water will enter the gearbox through this vent.

When the transmission oil is mixed with water, the performance of the transmission oil will be seriously affected, not only the lubrication performance is damaged, but the performance of the transmission power of the transmission oil will also decrease, and then the clutch plate will slip, and then the oil temperature will rise, which will also lead to the generation of water vapor and even make the oil-water mixture boil, these viscous substances will also accumulate in the valve body to cause the blockage of the valve body, thereby affecting the control system of the transmission.

After soaking in water, if you find that the vehicle does not go away, or there is abnormal shaking when refueling, I advise you to stop immediately, otherwise it will cause damage to the friction plate and other transmission mechanisms.

The safest way is to completely replace the transmission oil in time after the vehicle is blistered, fundamentally avoid the occurrence of the above situation, and the only solutions I can think of are these, for those models equipped with a transmission dipstick, you can apply the above method of checking the engine oil to determine whether the transmission is flooded.

What should I do if water enters the gearbox?

Solution to water ingress into the dry dual-clutch gearbox:

1. Water enters. Try not to drive and transport the first motive, so that the water enters the gearbox after the water is sunk at the bottom of the gearbox tooth oil, open the gearbox bottom of the oil drain wire after draining the water and oil. Add a new gear oil and you're good to go;

2. Dirty water or sediment water. When I enter the clear water and drive or run again, because the running and driving water are stirred with the oil at high speed in the stupid wax gearbox, the oil and water will emulsify, and the oil and water are difficult to separate;

3. This requires the gearbox to be removed and opened for cleaning, if the sediment collapses into the bearing, especially the one-shaft bearing, then all the components in the gearbox must be removed and cleaned.

The water in the clutch reduces friction and transmits torque. In the short term, it may have little impact on driving, but in the long term it may damage the three-plate clutch.

The clutch is located in the flywheel housing between the engine and transmission. The clutch assembly is screwed to the rear plane of the flywheel, and the output shaft of the clutch is the input shaft of the gearbox. When the car is moving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine and transmission, thereby cutting off or transferring the power input from the engine to the transmission.

The clutch is a common component in mechanical transmission, and the transmission system can be disengaged or engaged at any time. The basic requirements are: smooth jointing, fast and thorough separation; and easy maintenance; Small profile size; small mass; Good wear resistance and sufficient heat dissipation capacity; Fang Sui regrets to save effort, and the commonly used ones are divided into two types:

Jaw and friction type. The clutch is installed between the engine and the transmission and is an assembly part in the transmission system of an automobile that is directly related to the engine.

The clutch is usually installed with the flywheel block of the engine crankshaft, and is the part that cuts off and transmits power between the engine and the car's drivetrain. Throughout the entire process from start to normal driving, the driver can operate the clutch as needed, temporarily disengaging or gradually engaging the engine and drive train to cut off or transfer the power output from the engine to the drive train.

Its role is to gradually connect the engine and transmission, thus guaranteeing a smooth start of the car; Temporarily cut off the connection between the engine and the transmission, which is convenient for shifting gears and reduces the impact when shifting; When the car brakes urgently, it can separate and prevent the transmission system and other transmission systems from being overloaded, so as to play a certain protective role.
