    In terms of durability, DCT is more durable.

    Dual-clutch. The first feeling of the transmission is the "direct feeling" of driving, when as long as the throttle is lightly, you can feel the power gushing out of the engine, and the start is unambiguous. That's why many car companies like to use dual-clutch transmissions today.

    The DCT, on the other hand, has two clutches, so the shifting is also more supple, and the operation of shifting gears can be almost seamless. Its high-speed driving experience is close to that of a CVT.

    This is because dual-clutch transmissions are designed for high speeds, while DCTs are geared for low gears.

    It is relatively sparse, so sometimes it will lead to the phenomenon that the first gear is too sensitive, and the second gear is too sluggish. Thus giving the driver the illusion that he does not know which gear to shift from the gearbox. Whereas, the AT transmission has a torque converter due to the presence of a hydraulic torque converter.

    adjust, so the gear ratio handling at the beginning will be gentle.

    AT gearbox.

    Because there is a torque converter, the starting treatment will be more gentle than the DCT, but the "sense of directness" given by the starting is much lower. Because there is a fluid buffer.

    so that when the vehicle is turned off, you can directly let the transmission hang in 1st gear instead of neutral.

    Maintain the oil pressure of the 1st gear brake clutch, when the start-stop system works again, the car can rush out immediately, and at the same time, it also has a good climbing ability and strong starting power.

    The complex structure has also become a common problem of AT gearboxes. Due to the complex structure, it brings high manufacturing and maintenance costs. And by planetary gears.

    The gear shift mechanism is the inevitable frustration when shifting gears. In addition, due to the torque converter, the AT is more fuel-intensive than the DCT.

    Compared with the traditional AT automatic transmission, switching gear ratios without gears has become an extremely smooth thing, but the disadvantage is that the gearbox is protected during rapid acceleration and cannot release the maximum torque of the engine; Compared with the ordinary manual gearbox, the AT adopts a planetary gear structure, which cancels the clutch and uses a torque converter to connect the power, which can burst the maximum torque of the engine. Which works well depends on individual needs, and if you need to accelerate sharply for a long time, an AT gearbox is no better.

    Their internal structure and shift logic are not the same, and the AT gearbox is one of the best gearboxes available at the moment, and there are very few models on the market that use the DCT gearbox

    There are two automatically controlled clutches in the DCT gearbox for control, while the AT relies entirely on torque converter, that is, hydraulic oil, to achieve the front and rear power connection. Personally, AT is better to use.

    The gearbox is a bit complicated to explain carefully.

    In simple terms. CVT is infinitely variable speed, no gear, starting acceleration is relatively stable DCT is a double clutch, double clutch is divided into dry and wet, many problems are easy to have problems, simple structure, relatively cheap, many manufacturers in order to save costs, will choose DCT.

    AT automatic transmission, strong and durable, can withstand more torque, but the cost is relatively high, so many manufacturers will rarely choose AT gearbox.

    The DCT and AT gearboxes are better than the AT gearboxes.

    The AT type transmission is the most widely used transmission on the market today, and the penetration rate is the highest in the country. Traditional hydraulic automatic transmissions use torque converters or hydraulic couplings, multi-plate clutches, etc. It can cushion the power shock of the engine, coupled with the mechanical combination of planetary gears, the performance is stable, and the torque that can withstand is also very high, and even the tank has models that use AT gearboxes.

    Among them, AT technology will be more mature than DCT technology, DCT is a dual-clutch gearbox, and the main brother potato is divided into dry and wet type. At present, some high-end models use wet DCT, because it has a short time to change gears, and the engine can be perfectly matched, which can effectively reduce frustration and play a role in fuel saving, so most models will use formula DCT.

    The AT gearbox has a torque converter, so the starting handling will be gentler than the DCT, but the starting feeling is much less. By the action of dry hydraulic cushioning, when the vehicle is turned off, the transmission can be directly hung in 1st gear instead of neutral to maintain the oil pressure of the 1st gear brake clutch.

    When the start-stop system works again, the vehicle can rush out immediately, and it also has good climbing ability and strong starting power, so most models will use the formula DCT.

    The AT has the advantage of being durable, has great potential, and is suitable for deep modification or off-roading. The advantage of DCT is that it is fast in gear shifting and high in power transmission efficiency, which means that it is easy to drive and fuel efficient. At home, a suitable DCT gearbox is actually better.

    But whether it is AT or noisy DCT, it also depends on the manufacturer and model, the most excellent AT on the market is mainly ZF's 8AT, and Aisin 8AT, and other ATs are more ordinary, this ordinary is mainly compared from the perspectives of stability, economy and shift speed. The more excellent DCT is mainly the DQ and DL series of Volkswagen, as well as the seven-speed wet type of Getrag, and the wet DCT of other homes has some flaws in the smoothness and posture of the logo. So whether it's AT or DCT, you still have to look at it specifically.

    What is the difference between AT, CVT and DCT gearboxes? Which gearbox is better? It's an older topic of conversation, but it's also a topic that I'm sure everyone will have a new feeling.

    I went to a vehicle repair and the chosen location was a small repair shop. The size of the engine and transmission can be repaired ** motor maintenance storage and transmission. When the car maintenance consumed about 1 hour, in between, chatting with the owner of the car about how to choose the transmission problem, the repair car gave me a different experience.

    In his opinion, the best option for buying a car is in transmission, followed by CVT transmission DCT is not an option. Why did you choose this thing? Let's introduce according to the failure rate of the transfer!

    CVT TransmissionCVT transmission is also very popular in China. The most widespread use is Japanese cars. There are some domestic cars.

    CVT transmission is flat. The speed is high. The driving line of the vehicle is **, acceleration driving.

    Not at all, if it's a car, you'll love this transfer too.

    The shortcomings of the CVT transmission are also clear, the CVT transmission cannot carry large torque transmission, and although the CVT transmission has developed a wide variety of driving protection modes, the CVT transmission is very prone to sliding. According to the repairman solution, there are also a lot of CVT transmission issues. Many owners have sliding failures in their CVT transmissions, and when they speed up, the transmissions are no longer smooth and will occur.

    In this case, the owner is worried that after all, there is no way to solve the repairman, only to replace the transmission.

    Manual transmission: manual transmission is the most traditional and is more common in driving a kind of gearbox, manual transmission structure is simple, low cost, high transmission efficiency, although it is more troublesome in daily use, but there is a better sense of control, for some drivers whose driving skills are not very good, manual transmission has a certain difficulty in operation, and it is easy to stall. 2. The biggest difference between ordinary automatic transmission, ordinary automatic transmission and manual transmission is that there is no need to switch gears, ordinary automatic transmissions are used to achieve the purpose of gear transmission through hydraulic transmission and gear combination, which is more convenient for novice drivers, and the driver can step on the pedal with different strengths, and the gearbox can automatically lift the gear.

    3. Manual automatic gearbox: manual automatic transmission will integrate manual shift and automatic shift two modes together, manual automatic gearbox has obvious signs, due to the integration of the two functions, the gearbox will also be improved.

    The difference is that the structure and power transmission of these three gearboxes are different. Each gearbox has its own advantages and disadvantages, and overall I prefer the CVT gearbox, which is smooth and fuel-efficient, economical and efficient, and will not be a problem if you do not drive violently.

    Summary. In the case of these two gearboxes, this must be the AT gearbox is better. In the case of this gearbox, his performance is relatively stable, and the failure rate is relatively low.

    The difference between the AT gearbox is that the clutch and gear are the transmission in this gearbox. The structure inside is very complex, and the performance of this is relatively stable. Dual-clutch gearbox.

    The main reason is that if it has been used for a long time, or when it is driving at low speed, the gearbox shakes a lot. This gearbox is mainly a manual gearbox with two sets of clutch shift mechanisms, which is a dual-clutch gearbox.

    The DCT transmission and the AT transmission are the common automatic transmissions nowadays, but the performance of the two transmissions is not the same. Today, Bian Xiao will take you to understand.

    The DCT gearbox, also known as the dual-clutch gearbox, as the name suggests, consists of two clutches. In fact, it belongs to an automatic transmission rather than an automatic transmission, but it is made with automatic performance with new technology. At the end of the day, it's a manual transmission.

    In contrast to conventional manual transmissions, which use only one clutch, there is no frustration when changing gears because both clutches work at the same time, and the power is not interrupted when changing gears.

    AT transmissions are also known as hydraulic automatic transmissions (ATs). In complete contrast to the DCT gearbox, which has been fully automated on the basis of a manual gearbox. It can be said that the main function of the AT gearbox is an automatic transmission, but it also retains the manual transmission, which can satisfy some manual transmission enthusiasts or those who want to experience the fun of driving.

    Since there is no traditional hydraulic clearing residual device in the dual-clutch gearbox, the power of the starting slave can be fully utilized. At the same time, the two sets of clutches work alternately with each other, so that the shift time is extremely short, the engine power will not be interrupted, and the driving will be more stable when changing gears, and there will be no frustration and rolling. Shifting is more direct, power loss is less, and fuel consumption is naturally reduced.

    The main function of a hydraulic automatic transmission is an automatic transmission. The manual transmission will produce a certain shift frustration during operation, and its structure is relatively complex, so the fuel consumption is higher than that of the dual-clutch transmission. However, its manufacturing technology is mature, the product stability is good, the relative bearing capacity is stronger than that of dual-clutch gearbox, and the acceleration time is shorter.

    In general, DCT and AT gearboxes are not the same for people. If you are a fan of manual transmissions and want to experience automatic transmissions, you can opt for a dual-clutch transmission. If you prefer an automatic transmission and sometimes want to experience driving pleasure, you can choose an AT transmission.

    Comparison between DCT gearbox and Suihui AT gearbox, if you are driving in the city, Guess Chang A recommends choosing AT gearbox, AT gearbox is a little better in durability, and DCT is better than AT gearbox in terms of fuel consumption and smoothness of changing gears.

    Among them, AT technology will be more mature than DCT technology, DCT is a dual-clutch transmission, mainly dry and wet. At present, some high-end models use wet DCT, because it has a short shift change time, and the engine can be perfectly matched, which can effectively reduce frustration and play a role in fuel saving, so most models will use dry DCT.

    1. AT gearbox, because the AT transmission is in terms of transmission, as long as the torque converter effectively replaces the clutch, its principle is equivalent to two face-to-face fans, and after one of the fans is energized, due to the flow of air, it will drive the other fan to rotate.

    2. DCT gearbox, this is a dual-clutch gearbox, and the structure is similar to the way two AMT gearboxes are superimposed together. However, there will be two clutches in DCT, where K1 is responsible for gear, and K2 is responsible for gear and reverse.
