How many kilometers can dry dual clutch generally use? Can the dual clutch drive to 500 thousand kilometers?

As far as Volkswagen's dry dual clutch is concerned, under normal circumstances, the dry dual clutch is within 300,000 kilometers, and it is necessary to change the clutch when it reaches 6,543,800 kilometers. Of course, it depends on the actual use, but it seems that no car can run 300 thousand kilometers with dry dual clutch, because 300 thousand kilometers is too worn for dry dual clutch, and it is difficult to guarantee that it can run such a long distance normally.

Can the dual clutch drive to 500 thousand kilometers?

500,000 kilometers, this mileage is an idiotic dream for dry dual clutch, but it is different for wet dual clutch. Because the wet dual clutch has excellent heat dissipation performance and extremely low loss, it is not a big problem to drive 500 thousand kilometers. However, between these 500,000 kilometers, it is recommended to check the clutch every 6.5438+10,000 kilometers.

Of course, even if it is a wet dual clutch, the mileage depends on the usual car habits. Because the dual clutch is not suitable for long-term low-speed driving and too ordinary starting, otherwise it will easily lead to clutch heating and affect its service life.

What's the difference between dry double clutch and wet double clutch?

The fundamental difference between the two clutches lies in the different working environment. Let's talk about dry dual clutch first. The working environment of dry dual clutch is in direct contact with the engine flywheel, and the whole clutch is exposed to the air, and the heat is taken away by air cooling when working.

The advantages of this kind of clutch are also obvious, that is, it is cheap and simple in structure, so it was widely used in Volkswagen in the past. However, the disadvantage is also obvious, that is, it cannot bear too much torsional load, and as an air-cooled clutch, its heat dissipation efficiency is also very low, and it is easy to overheat, which affects its service life.

Let's talk about what a wet dual clutch is. Different from dry double clutch, wet double clutch is to soak the clutch in engine oil and then take away heat through engine oil circulation. With the development in recent years, this clutch technology is more mature and reliable.

Because the wet dual clutch is oil-soaked, it has higher heat dissipation efficiency and can bear greater load. It can be installed on vehicles with displacement of 1.6L or above, and it is also a kind of clutch widely used by the public at present. Of course, the disadvantage of this kind of clutch is also obvious, that is, the manufacturing process is higher than that of dry dual clutch, which leads to higher price. And it is more troublesome in terms of maintenance.
