With the continuous development of science and technology, automatic cars have become the mainstream of the automobile market, and most consumers will choose automatic cars when buying cars. There are three categories of automatic cars: AT, CVT and dual clutch, which are dazzling. So how do novice drivers choose AT, CVT and dual clutch when buying a car? Today, I will give you a good science popularization.
First of all, let's talk about the popular dual-clutch gearbox in recent years. As the name implies, the dual clutch gearbox has two clutches. One of them is responsible for odd gears, and the other clutch is responsible for even gears. Compared with other gearboxes, the dual-clutch gearbox has the advantages of fast shifting, smooth shifting and fuel saving, which is why major automobile manufacturers have to develop the dual-clutch gearbox even if it is difficult.
Dual clutch gearbox is divided into wet dual clutch and dry dual clutch. The structure and shifting principle of the two are the same, and the difference lies in the heat dissipation mode of the clutch.
The heat dissipation of dry dual clutch depends on airflow, while the two groups of clutches on the wet dual clutch are immersed in the oil cavity and rely on ATF circulation to take away heat, which is more stable to use. Moreover, the wet dual clutch has a long service life and generally does not break down.
Although the dual clutch gearbox has many advantages, it is not suitable for novice drivers. Because the dual clutch gearbox is difficult to operate, especially in traffic jams, it is difficult for novices to operate well, and a rear-end collision will happen if they are not careful.
Since dual clutch gearbox is not suitable for novice drivers, is AT gearbox suitable for novice drivers? Compared with the other two gearboxes, AT gearbox can be said to be a more traditional automatic gearbox. It is connected with the engine through a hydraulic torque converter, thus transmitting power to the gearbox. The advantages of AT gearbox are good ride comfort, stable quality, tacit cooperation with engine, simple operation and friendly to novice drivers. However, the cost of AT gearbox is relatively high, and there are fewer models on the market. Everyone must consider their own economic strength when buying.
Finally, let's talk about CVT gearbox, also called continuously variable gearbox.
Because CVT gearbox has no fixed gear, the power output is continuous and linear when the vehicle accelerates, so the driving process is very smooth. Especially in the city stop-and-go road conditions, the comfort is very high, which is very suitable for novice drivers to drive. Moreover, the cost of CVT gearbox is relatively low, and there are many models to choose from. The CVT gearbox has a poor sense of acceleration and lacks certain driving pleasure. Novice drivers who like to pursue driving excitement must think carefully.
Generally speaking, these three gearboxes have their own advantages and disadvantages. If you have a very good driving experience, you can try dual clutch. If you want to drive safely, try CVT. If you want something taller, you can buy it now.
