How does a 6 speed wet dual clutch transmission compare to a 6 speed automatic transmission?

The wet type is more reliable, but it is also more oil-intensive; Dry is fuel-efficient, but Volkswagen's DSG experience has shown that dry dual-clutch transmissions are more prone to problems in the Chinese environment. View the original post

I think the dual-clutch transmission should be chosen, because this kind of transmission is more reliable and has more transmission power.

I think the latter should be chosen, because the car with an automatic transmission is simpler to drive and has a longer life than the former.

I think the former should be chosen, because the dual-clutch transmission has less power loss.

1. The attributes of the two are different: the six-speed dual-clutch is wet, while the seven-speed dual-clutch is dry. 2. The maintenance cost of the two is not the same

The maintenance cost of the seven-speed dual-clutch is higher than that of the seven-speed dual-clutch. 3. The working principle of the two is different: the six-speed double clutch refers to the multi-plate clutch with two sets of coaxial installation of a large and a small clutch, which are installed in a closed oil cavity filled with hydraulic oil, so the clutch structure has better adjustment ability and excellent hot melting, and it can transmit relatively large torque.

6AT automatic transmission.

Also known as automatic.

The automatic transmission is composed of a hydraulic torque converter, a planetary gear transmission, and a control mechanism. With the ability to automatically shift gears and torque according to road conditions, the driver can keep an undivided eye on the road traffic without being distracted by gear shifts.

Advantages of 6AT automatic transmission: smooth, fun, stable quality, small size, wide transmission range;

Disadvantages of 6AT automatic transmission: precise structure, high cost, difficult mechanical manufacturing, generally speaking, the efficiency is lower than that of DCT;

Relatively speaking, the 6AT is not easy to break, but there is a pause in shifting gears, and the fuel consumption is high. The CVT shifts smoothly but doesn't withstand much torque.

To sum up, 6AT automatic transmission.

Makes driving simple, avoiding tedious gear shifts while manual transmission.

However, it can make the owner feel the fun of driving, and the automatic manual transmission can switch between the two.

This car is OK to drive, the speed is slow, but acceptable, the car is heavy there, the displacement is there, the overall is very good, in the past to drive Jetta, wife and children motion sickness, now no motion sickness, this car from the first place of workmanship materials, it is worth starting, I feel right, fuel consumption also surprised me, I expect the following, so overall it is a good car, my engine is a little.

Due to the difference in the car, its configuration is also different. Car companies will control the cost of car manufacturing according to the market, just like why some models choose dual-clutch gearboxes instead of automatic manual transmissions, in fact, they are all to improve profit margins. Then even the 6AT transmission is different in terms of technical level, and today I will give you an analysis of the specific situation.

1] Powertrain form.

naturally aspirated engine + AT gearbox;

naturally aspirated engine + DCT dual-clutch transmission;

turbocharged engine + AT gearbox;

Turbocharged engine + DCT dual-clutch transmission.

2] Advantages and disadvantages of AT manual automatic transmission.

The biggest advantage is that the failure rate is relatively low, the acceleration smoothness is good, and there will be no frustration of the dual-clutch gearbox, which is also the first choice of many old drivers. Then it also has shortcomings, it will not have a strong push-back feeling like a dual-clutch transmission, and the AT transmission is slower when accelerating in the front, but acceleration in the middle is still okay. The current mainstream configuration is a 6-speed transmission, and a 10-speed transmission may be available in the future.

3] AT gearbox is inherited from generation to generation.

Even if they are all 6AT gearboxes, their parameters are not the same, there are AQ160 and AQ250. The difference between these two gearboxes is also significant. So how do we consumers identify it?

It is not visible at all from the appearance and configuration table. However, there is a slight frustration when accelerating from 2nd gear to 3rd gear, and the engine speed decreases in 3rd gear, which is caused by the failure to lock up 1st and 2nd gears. If this happens, it means that this is an old AQ160 transmission, and everyone should be cautious.

What does a 6at gearbox mean?

First of all, automotive transmissions can be divided into manual transmissions and automatic transmissions, and AT is what we often call automatic transmissions. Generally speaking, automatic transmissions have gears such as P, R, N, D, or L. And 6AT is the six forward gears, that is, six gear sets with different gear ratios, such as 4AT, 8AT, 9AT and even 10AT.

Although the previous numbers are different, they are all derivatives of automatic transmission technology.

What does a dual-clutch gearbox mean?

A dual-clutch gearbox simply has two sets of clutches.

Work at the same time. One group manages odd-numbered files, and the other group manages even-numbered files. This design is to avoid the problem of power interruption during traditional manual shifting, so as to achieve the purpose of fast shifting.

Dual-clutch transmissions are called differently by different manufacturers. Volkswagen is called ds g, Audi.

It's called S-Tronic, Porsche.

It's called PDK. As the core component of the car, the gearbox has a great relationship with the performance, safety and stability of the car. When buying a car, friends who know cars often take the gearbox as the focus of consideration.

Today we're going to talk about two gearboxes of the same grade. 6AT and dual-clutch.

Which is better, 6AT or dual clutch? First of all, the AT is an automatic transmission.

The most mature technology developed earlier than the dual-clutch transmission, and the 6AT transmission, especially the Aisin 6AT transmission, is called "in the market." The best gearboxes", from Geely's Borui and Boyue to Changan's C S5 5 and CS95 , from Toyota's Prado.

and Highlander to Mazda.

CX-4 and Artez and so on, we can see the figure of 6AT, which can be described as the listed "Xiang Bo".

Dual-clutch transmissions, especially Volkswagen's DSGs, can be described as a love-hate mixture. On the one hand, it has unparalleled shift speed and fuel economy, but on the other hand, it has frequent problems such as high failure rate and serious frustration. While there have been improvements, some of the technical flaws are not quite **.

Even so, many manufacturers still have not given up the development and use of dual-clutch transmissions, including many models with great potential.

At present, the 6AT is undoubtedly superior to the dual-clutch transmission in terms of reliability. Although it will consume more fuel than a dual-clutch gearbox, the quality is absolutely ***. But don't speak ill of the double clutch.

After all, the advantage of manufacturing cost is enough to make many manufacturers rush to it, and the current wet dual clutch also makes up for the disadvantages of the previous dry clutch. With the increase in capital and technology investment, the future is immeasurable (6at: young people, the future is yours).
