First of all, automatic transmission , as the name suggests, is a car that does not require the driver to manually shift gears, because the vehicle will automatically select the gear according to different driving speeds, and the so-called continuously variable transmission, automatic manual , dual-clutch all They are all collectively called automatic transmissions, so as there are more novice drivers now, automatic transmissions are also becoming more popular because of their easier operation.

Therefore, car brands on the market have begun to mainly release automatic transmission cars. And because the market is full of automatic transmission cars, a cycle has been formed in which everyone buys automatic transmissions. Originally, everyone thought that automatic transmissions would be more convenient and more convenient. It was a good choice, but it turned out that the transmissions of automatic cars are also divided into manual, CT, and dual-clutch.

We finally chose automatic transmission between these two major types of cars, manual transmission and automatic transmission. Now, hello, we are faced with a situation of choosing one of three. So how should we choose? In fact, no matter how you choose, each one has its own advantages and advantages.

Therefore, we should judge which one is more suitable for us based on our actual situation. If you don’t have big requirements when buying a car and just choose it as a simple transportation tool, then it’s really It doesn't matter which one, there is basically no difference.

First of all, "automatic manual" can be understood literally. To put it bluntly, it is a combination of manual transmission and automatic transmission. If we insist on going into details, in fact, the manual transmission operation in manual transmission, It's just simulated through a computer system, and the purpose is to win over some experienced drivers who like to drive manual transmissions.

After all, almost everyone knows that manual transmission can better reflect the skills of experienced drivers, and many experienced drivers think that automatic transmission is boring, so the automatic manual transmission relies on gears to transmit torque, and then through A hydraulic torque converter is used for buffering, taking into account the needs of experienced drivers and the operability of novice drivers.

is very easy to use because of its soft start and gentle speed. It is also the most popular one on the market. In addition, this kind of selective development was earlier and the technology is relatively mature, so it is less likely to malfunction. It also feels better to use, just because the characteristic of this mode itself is that it is not very efficient, so it consumes relatively more fuel.

Secondly, "Continuously Variable Speed ​​CT" Although the name of this stepless machine sounds unclear, we can also understand from the literal meaning that continuously variable speed can be achieved without any level restrictions. It probably means that the speed can be changed as desired. There is no so-called speed unit limit.

Continuously variable transmission mainly relies on gears to transmit torque, two variable diameter transmission wheels and an intermediate transmission belt to transmit power, and the computer is responsible for changing the speed and throttle, so it can achieve continuous transmission. Of course, it is not There are no shortcomings. In the past, the poor material of the transmission belt and had greatly limited his technology.

Although the material problem has been improved until now, the specific situation still depends on the car it is equipped with. Because some car brands are not willing to spend money, the materials they are looking for are not particularly good. So this is will directly affect its performance.

Generally speaking, the continuously variable transmission is more comfortable and smoother in shifting and consumes less fuel. The problem is that the technology is not particularly mature yet, and the power problem has not been well solved. I believe that everyone is familiar with the relevant functions of the clutch. We all know very well that it is mainly responsible for the switch between the engine and the gearbox.

As the name suggests, the so-called "dual clutch" chooses two clutches to cooperate, one for odd-numbered gears and one for even-numbered gears. So overall, dual-clutch can perfectly solve the problem of power lag caused by untimely shifting. , its characteristics are strong power output, higher efficiency and less fuel consumption, but it may suffer from insufficient power at low speeds.
