What is the biggest difference between a wet clutch and a dry clutch? What do you think?

The biggest difference between wet clutch and dry clutch is the cooling method of the clutch friction plate.

First of all, the role of the clutch is to transmit or block the engine power of the car parts, and the main role of the clutch is the clutch friction plate. The author believes that the clutch friction plate is inevitably subject to friction in the process of transmitting or blocking power, and friction will dissipate heat, and the clutch dissipation mode of wet clutch is through clutch oil conduction heat dissipation, while dry clutch is air conduction heat dissipation. There is a difference between the two clutch methods is that the clutch effect of the dry clutch is better, because the dry clutch has no oil barrier, which can make the bite faster, and the bite strength is greater, so that the clutch conducts engine power better, in addition, the wet clutch and the dry clutch also have the following three differences:

1. There is a difference between wet clutch and dry clutch in fuel consumptionDry clutch is more gasoline efficient than wet clutch, because the wet clutch is equipped with a hydraulic cooling system, this hydraulic cooling system plus clutch oil will increase the overall weight of the car, and the hydraulic cooling system also needs the power support of the engine, so through these two aspects, the fuel consumption of wet clutch cars is higher than that of dry clutch cars.

2. There is a difference between wet clutch and dry clutch in service lifeThe service life of the wet clutch is longer than that of the dry clutch, because the wet clutch can conduct the heat of the clutch friction plate faster, especially when the car is in a semi-clutch state in the bustling city. The clutch plate is at a high temperature, and the wet clutch conducts heat more efficiently than the dry clutch.

So the wet clutch lasts longer.

3. There is a difference in the frequency of friction plate replacement between wet clutch and dry clutchThe frequency of changing the clutch plate is significantly lower with a wet clutch than with a dry clutch. Because the wet clutch has a cushioning of clutch oil between the clutch and the transmission, it is less worn than a dry clutch, so the frequency of damage and replacement is reduced.

It can be seen that wet clutch and dry clutch have their own advantages and disadvantages, and how to choose depends on the different preferences of individuals.

The biggest difference is that the handling performance is different, the working environment is different, the working principle is different, and the torque transmission efficiency is different. I think the wet dual clutch will be more expensive to manufacture.

Wet clutch The occlusion response is fast, and the occlusion force is relatively large. When the torque is transmitted, it is not very clear; Dry clutches require frequent shifts while in use, and unless the technology is superior, the handling is still poor,** compared to wet clutches,** relatively low.

There are two common braking methods in dry clutch and wet clutch cars, but there is a certain difference when working. Most cars now use dual-clutch transmissions.

Dual-clutch transmission.

It is divided into dry dual-clutch transmission and wet dual-clutch transmission. The principle of both dry and wet transmission is basically the same, with two clutches.

Work in separate turns. However, the connecting medium of the driving disc and the driven disc of the clutch is different, the dry dual clutch relies on air, and the wet dual clutch relies on oil.

Wet dual clutch plates are clutch plates that are immersed in transmission fluid, while dry dual clutch plates are in direct contact with the engine flywheel. From the level of technical maturity.

In terms of reliability, the wet dual clutch works in hydraulic oil due to the clutch plates.

, the oil has a certain heat dissipation effect, so it is more stable to use. Because of poor heat dissipation, dry dual clutch is prone to the risk of high temperature or even ablation of clutch plates in congested urban areas. At this level, the wet dual-clutch transmission technology is more mature.

At the same time, the wet dual-clutch structure is complex, the manufacturing cost is high, and its power transmission efficiency is not as high as that of the dry type.

The difference between a dry clutch and a wet clutch is that the connection medium is different: the dry clutch is air; The wet clutch is the fluid. 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.

The clutch is not a brake, if it is a pure automatic car, there is no clutch, only brake and throttle. The clutch can not be used as a brake, if you press the clutch when going downhill, the speed of the car will be faster, because the transmission device is disconnected from the wheels, the engine can not control the car, and the speed of the car will be faster under the action of gravity.

The differences between dry and wet clutches are:

1. Different torque transmission efficiency Because there is no clutch oil barrier, the dry clutch can control the power engagement and separation lightly and freely, and can work in a semi-clutch state in a short time, with a faster occlusion response and a larger occlusion force. Wet clutches, on the other hand, are less defined when it comes to transmitting torque.

2. **Different Compared with the car with the wet clutch, the car with the dry clutch is relatively lower.

3. Different handling When the dry clutch is used, it needs to be frequently shifted, unless the technology is excellent, otherwise the handling is still worse than the wet clutch.

4. Different service life Due to the air cooling used, the friction plate can not be cooled well compared with the wet clutch, especially when the car is in a semi-clutch state for a long time in the urban area, the friction plate of the clutch will be in high temperature work.

The transmission efficiency of torque is different; The bending dry clutch does not have the barrier of the clutch, and can easily control the power combination and separation, and the spike bridge can work in a shorter time in a semi-clutch state and its power is more sufficient, while the wet clutch is not so clear and fast when transmitting torque. Bury the clan accompaniment.

The biggest difference between dry clutch and wet clutch is that the efficiency of transmission is different, because the way of dry clutch and wet clutch and cooling is different, and the structure and working principle are different. Manuscript group.

The wet clutch has better coherence, no obvious frustration, the driving experience is smoother, the dry clutch has a low failure rate, and the difficulty of later maintenance is low.

The manual transmission is a dry clutch, if there is oil, the car can not be driven if it is skidding, and the clutch of the automatic transmission is in the box, and it is wet by hydraulic combination.

Wet clutch: It is the clutch and the gear wheel that are soaked in oil together.

Dry clutch: Quite the opposite.

Difference Between Clutch Dry and Wet:

1.Dry friction is relatively large, but it is easy to heat up.

2.In order to dissipate heat, the clutch is dissipated by using the oil in the crankcase, which is called a wet clutch.

Dry: Reflect quickly, noisy and wear.

Wet: durable, low noise.

Scooters are generally dry clutches and many two-stroke cars are dry.

What is the difference between a dry clutch and a wet clutch? What is the difference between a dry clutch and a wet clutch? A lot of people don't know yet. Now let's take a look!

1.The difference between dry hail clutch and wet clutch: There is no essential difference between dry clutch and wet clutch in terms of working principle and basic structure.

The difference lies in the way the clutch friction plates are cooled: the two sets of clutch plates of the wet clutch are in a closed tank, and the transmission oil soaked in the clutch plates absorbs heat.

2.The friction plates of the dry clutch do not have a sealed oil groove and require an air-cooled friendly bridge sail.

Dual-clutch transmission, I believe everyone understands, but it can also be subdivided into dry clutch and wet clutch. They don't seem to be just one word, but they can all be different in terms of performance.

The structure of the wet clutch is more complex than the dry clutch, the dry clutch generally adopts the form of air heat dissipation, and the wet clutch adopts oil immersion heat dissipation, that is, the clutch plate is soaked in the transmission oil, so that the oil absorbs the heat generated by it and then achieves the cooling effect, and the heat dissipation efficiency is high. From the perspective of transmission efficiency, the wet clutch cannot avoid internal friction in the process of transmitting power due to its complex structure, so the dry clutch has an advantage in transmission efficiency.

Although the dry clutch has a simple structure, it is not as good as the wet clutch in terms of torque bearing, because most of the dry clutch structure is composed of metal, and if the torque is too large, it is inevitable that the structure will be damaged due to severe friction. But in terms of shift speed, the dry type is faster than the wet type; In terms of stability, the wet type is better than the dry type.

In general, the dry type is mostly used with turbocharged engines with less power and displacement, while the wet type is used with turbocharged engines with more power and displacement. Therefore, the right configuration with the right model can better play the performance advantages of the whole vehicle, perhaps its performance is different, but it does not affect the car experience, that is an excellent combination.
