Which is better, dual-clutch gearbox or cvt gearbox?

Transmission to a large extent determines the transmission efficiency and driving texture, even if the engine power parameters are strong, there is no good transmission to match, it is useless.

So when buying a car, you can not worry too much about engine parameters, but you must not ignore the importance of the gearbox.

Master Bang first introduce the advantages and disadvantages of the dual-clutch gearbox.

Advantages of dual clutch

The double-clutch equipped with the vehicle is divided into two clutches, which control the odd-even gear of the vehicle respectively. When using the vehicle, the vehicle is hooked into one gear, and the corresponding next gear will be automatically prepared, so that the vehicle can be changed faster when the owner refuels.

The dual-clutch transmission and turbocharged engine are the golden combination of vehicle configuration, and the vehicle equipped with the dual-clutch transmission is also very abundant in power, compared to other models of transmission is much better.

Disadvantages of dual clutch

The most common fault of vehicles equipped with dual-clutch transmission is the high temperature of the clutch plate, especially when driving in the congested section, the vehicle frequently shifts, so that the clutch plate temperature is too high, and the clutch of the vehicle is easily damaged for a long time.

This transmission shift speed is fast, and when the vehicle shifts at high speed, the driver will feel a significant sense of frustration.

Dual clutch VS CVT

First of all, let's talk about the popular dual-clutch transmission in recent years, which, as the name suggests, has two clutches. One of them is responsible for odd gear, and the other clutch is responsible for even gear. Compared with other gearsets, dual-clutch has the advantages of fast shift, smooth shift and fuel saving, which is why major automobile manufacturers have to develop dual-clutch gearsets even if they are difficult.

Dual-clutch gearbox is divided into wet dual-clutch and dry dual-clutch, the structure and shift principle of the two are the same, the difference is the heat dissipation mode of the clutch. Dry dual-clutch heat dissipation relies on air flow to take away heat, while the two sets of clutches on the wet dual-clutch coaxial are soaked in the oil chamber and rely on the ATF cycle to take away heat, so it is more stable to use. And the wet double clutch has a long service life and generally does not fail.

Although it has many advantages, it is not suitable for novice drivers. Because it is very difficult to operate, especially in traffic jams, it is difficult for beginners to operate well, and accidentally rear-end accidents will occur.

Since the dual clutch is not suitable for novice drivers, is the CVT gearbox suitable for novice drivers? CVT transmission is also known as stepless transmission. Because the CVT gearbox has no fixed gear, the power output is continuous and linear when the vehicle accelerates, so it is very smooth during driving. Especially in the stop-and-go road conditions in the city, the comfort is very high, very suitable for novice drivers.

Moreover, the CVT transmission cost is relatively low, and there are more models to choose from. However, the CVT gearbox has poor acceleration and lacks a certain amount of driving pleasure, and novice drivers who like to pursue driving stimulation must consider it clearly.

In general, the dual-clutch and cvt gearbox have their own advantages and disadvantages, after all, if the gearbox is all advantages, it has long occupied the market. Therefore, when buying a car, there is no need to treat the dual-clutch model as a flood, and it is OK to choose according to the above description.
