Why do many people now buy new cars without considering dry dual clutch?

Dual clutch gearbox, as the name implies, there are two sets of clutches in the gearbox. When shifting gears, it can work alternately to achieve the effect of seamless connection. Its biggest feature is fast shifting speed and outstanding ride comfort, and it can also reduce fuel consumption. Because of the existence of Volkswagen, DSG dual clutch gearbox became famous in one fell swoop. It once existed like a god in China, and even many people only recognized the dual clutch gearbox when buying a car.

However, dual clutch gearboxes are also divided into dry and wet types. Generally speaking, wet clutch means that the clutch is immersed in automatic transmission oil to dissipate heat, while dry clutch, like manual clutch, relies on air to dissipate heat. However, in the big cities of China, the dry dual-clutch gearbox is very cheap, frequently starts, drives at a low speed or stops for a long time, which is particularly prone to overheating of the clutch, which will seriously lead to failure. And if the gearbox is overheated, you have to stop and wait for it to cool down, which is also its most embarrassing place.

In contrast, wet dual clutch gearbox is more popular in China. Because of the transmission oil, although the power transmission rate is slightly lower than that of dry type, the clutch plate has low wear degree and high heat resistance. If the engine torque is too large, the dual clutch gearbox is the best choice, and it is faster in the face of fierce driving. The wet dual-clutch gearbox is generally used in high-end vehicles because of its complex structure and high maintenance cost.

As we all know, the double clutch gearbox has had a very big "public relations crisis" in China. But now the technology of dual clutch gearbox has made a qualitative leap, and people's impression of dry type may still stay in the past, which leads many people not to consider dry dual clutch gearbox when buying a car.
