What do you think of cars with dual clutch transmissions, and why aren t many people buying them?

The essence of the dual clutch is to add electronic control to the manual transmission. The person who turns on the manual transmission knows that a slow lift of the clutch will be smooth, otherwise there will be setbacks. The same goes for the dual clutch.

To ensure smoothness, we had to slow down the pace of shifting, which is the exact opposite of what some say about fast shifts with the dual clutch. Many dual-clutch models have the bad feeling of pedaling lightly and not pedaling heavily. In short, the dual-clutch experience isn't great compared to other forms of gearboxing.

Of course, this is the earliest series of failures of the Volkswagen Prime and the transmission, but now it is slowly solved, and now with the improvement of dual-clutch transmission technology, the dual-clutch transmission is becoming more and more stable, so many of us think that the dual-clutch transmission is not very good, because the early dual-clutch transmission failure, leaving a bad impression Some supercars also use dual-clutch, but obviously different from our ordinary civilian cars, and the adjustment direction is also different. In addition, the stability and durability of the dual clutch is also the bottom level of all transmissions. Since there is no torque converter, gears of different speeds rely on hard sliding wear of the clutch.

Manual transmissions can reduce clutch wear through skilled operating skills, while dual-clutch electrically controlled clutches are not so straightforward. As a result, many dual-clutch models work well in new cars, and problems such as setbacks, overheating protection, and so do after a few years.

It's not good because it's easy to break, and in fact, a good dual clutch shifts quickly and is fuel-efficient. It's fun to drive, but it's easy to break. This has to do with the structure of the dual clutch itself.

The Volkswagen Group's dual clutch is the best on the market. Early dry dual clutches generated a lot of heat during frequent shifts at low speeds and could not be cooled. After a long time, it was easy to have problems, and now the wet type is much better, as for other brands, especially domestic dual clutches, they still don't do it well enough.

Because of the low threshold and low cost of this kind of transmission, many car companies will not choose. In fact, for dual-clutch transmissions, even now, many people still think that dual-clutch transmissions are relatively poor in reliability and have a relatively high failure rate.

In fact, this is mainly due to the fact that the failure rate of dual-clutch transmissions was high in the beginning and even now, such as the Volkswagen, which was the first to be equipped with dual-clutch transmissions, often had particularly serious problems! For example, the gearbox is seriously frustrated by gear shifting, the abnormal gearbox jumps, and even cannot be shifted, and the vehicle cannot drive normally. But now for the best-performing gearbox, or only dual-clutch transmissions belong to the first echelon!

It has a very fast shift speed, a very efficient transfer efficiency! It can make us high performance! However, due to the relatively high maintenance cost of dual-clutch gearboxes, we need to match the worn dual-clutch for a certain period of time, otherwise our clutch will become more clearance after wear, there will be frustration in shifting, and our efficient dual-clutch needs to be replaced.

I think that the car with dual-clutch transmission is not very good to use, the experience is not good, not many people are willing to buy it, it is not very affordable, the service life is not high, it is not conducive to care, and it is not convenient to clean.

Most people think that the dual-clutch transmission car has obvious disadvantages, the overall fuel consumption is relatively high, the car power output has a series of problems, and the transmission heat dissipation is not good. Because everyone clearly recognizes these disadvantages, and the cost performance is not high, so there are not many people who buy it.

The dual-clutch gearbox is mainly because the technology is immature at the beginning, resulting in frequent problems with the dry dual-clutch, if you encounter frequent gear changes, brake start, dry dual-clutch will have high temperature abnormalities. At present, with the improvement of dry dual-clutch technology and the emergence of wet dual-clutch, the incidence of dual-clutch failure has decreased.

Many people feel that this vehicle is more fuel-intensive, and the performance of the vehicle is not particularly good, the vehicle has more defects, more problems, and more faults.

The dual clutch does have many advantages, but the disadvantages are also great, this product was originally a product of racing, the racing road conditions are single, you don't need to consider too many factors, but civilian is different! It's much more serious than adapting to the local area! In the past, the mechanic always said that the dual-clutch transmission was the most repaired by Volkswagen.

Is the car mechanic still saying that? When do they fix the car? At least in my opinion, the DCT transmissions that Volkswagen and Hyundai are doing now are good, at least the shifts are smooth, and the durability is not bad!

To sum up, in the Chinese market, dual clutches have always been synonymous with mid-to-high-end, and car salespeople also respect dual clutches very much. In principle, it really is the top category of transmissions! However, due to the harsh working environment, it is destined to be natural and sophisticated!

Due to the high volume of vehicles, there are always some vehicles that have performance deviations due to the manufacturing process, but the percentage is very small. For example, if we sell 1000 cars, there may be a problem with several cars, all of which will appear. This requires us to carefully inspect the vehicle when buying it!

There's nothing inherently wrong with the dual-clutch, it's just that we use good things in environments where it's not good at!

The dual clutch is not as bad as you think, ten years ago, the dual clutch has just developed, the technology is not perfect, there is always a shift shake phenomenon, and the double clutch overheats from time to time, resulting in the vehicle can not be driven normally, but this is the old yellow calendar, now the 7-speed dual clutch is very good, at least the shift jitter, clutch durability, can meet everyone's requirements, will not affect normal driving! There are many advantages, such as transmission efficiency, high efficiency, high torque carrying capacity, and urgency of shift response. Since it is a mechanical gearbox, the reliability of the case is also guaranteed.

Therefore, it is mainly used in sports vehicles and is highly sought after by young people.

The problem is basically focused on dual clutches, especially dry dual clutch transmissions. High temperature resistance due to frequent clutch shifts. Many users who work with cars and urban road conditions often worry about breakdowns.

Waterproofing issues with the clutch can also lead to prolonged shutdown failures. The impact when shifting in low gear could be improved. To sum up, it depends on the individual to focus on the pros and cons.

If you love a car, you must love its strengths and weaknesses. Do you appreciate his strengths and tolerate his shortcomings?

For dual-clutch gearbox cars, their sense of action is relatively sufficient, and it will lead to overheating of the temperature, which will often wear out the clutch, thus affecting the driver's driving experience; The reason why there are so few people who will buy Jianfan is because his reputation is very general, and it cannot effectively meet the needs of consumers, and the maintenance cost in the later stage is relatively high.

The heat dissipation is not particularly good, there will be failures, the maintenance cost is relatively high, and the energy consumption loss in the transmission process is relatively high. Clutch plates are susceptible to damage. Due to the fact that there are many shortcomings in the transmission of this car, fewer people buy it.

This kind of car is not suitable for home use, maintenance and later maintenance costs are relatively expensive, a year of nuclear about tens of thousands of dollars, the failure rate is very high, the heat dissipation situation is not very good, in the process of driving comfort is more Lu Heng poor to accompany the family to do, will produce serious frustration, so the family car is more recommended is the wet dual-clutch.

The transmission efficiency of this virtual beat pin car is higher than that of the poor swim, and then the speed is relatively fast when the silver grip shifts, the power loss is relatively small, the gear change is very direct, the fuel economy is also very high, and the fuel consumption is relatively low; Overall, there are more advantages than disadvantages.

This is because even if this kind of vehicle is not good, it has a large market share, and the market share is relatively broad.

Such a car is relatively stable and bright when starting and running, and it is very convenient to change gears, and there will be no frustration, and then the drive train will not be overloaded, and the wheels will not suddenly slow down.

Due to the structural and design factors, you want the DSG to be smooth, dynamic and responsive and direct, so in low-speed tracking in congested environments, the transmission logic determines whether to accelerate or decelerateTherefore, the frequent preparation and switching process of two sets of clutches inevitably leads to frequent half-clutch conditions, coupled with the concept of public environmental protection to seal the clutch in the valve body, especially the dry dual clutch plan to avoid dust entering the air polluted environment, which further leads to overheating of the low-speed half-clutch. The current Volkswagen 7DCT, when the vehicle is driving at low speed, switches to 2nd gear in advance and <>

In the case of traffic jam, the vehicle stops in time, and the transmission is still in 2nd gear, so that the vehicle is started or when the traffic jam is not.

The first and second gears are switched, and the dual clutch is stupid and the old transmission is low-speed.

The jitter phenomenon of the first and second gears is directly eliminated. Therefore, if the public wants to continue to let the dual clutch exist, they must change their publicity strategy and no longer show off the advantages of their car's genes and comfort, but face its cheap characteristics. The gearbox slows down the logic of low-speed shifting, avoiding the half-clutch that is frequently beaten.

So now you'll feel that the dual clutch is unsatisfactory at low speeds and the response is unsatisfactory, the power is always slow at low speeds, and the keep gap always increases by three to <>

But the throttle gives more power than expected, the foot brakes, and some people are not willing to endure these pains and just cut into manual mode driving, so the failure rate is much lower, and there is no question of whether the car is comfortable or dynamically responsive after the speed increases. Therefore, after the test drive of the Sutar and Lavida, the two cars have a very high degree of smooth gear shifting when driving at low speeds. Even in a traffic jam, the vehicle still doesn't shift gears and shakes, except in the process of rapid acceleration, when the second gear will be in first gear and the vehicle feels a little shaky.

In the normal course of the vehicle, there are no problems at all. However, when Volkswagen's design directly leads to traffic jams, the vehicle is slightly less responsive.

Volkswagen dual-clutch transmission, the early problem is mainly the low speed of the vehicle, the dual-clutch transmission is easy to shift frequently, in the process of shifting, the clutch is not fully combined, but due to the sliding state, the temperature of the transmission clutch friction plate is very high, the higher the temperature, the more difficult the dual-clutch transmission control. Volkswagen has strong transmission stability and good acceleration phenomenon during driving. When stepping on the accelerator, the vehicle power changes strongly with the throttle line**, and there is no obvious sense of turbo intervention, but the vehicle response is slightly insufficient, and there is no acceleration impact of Japanese cars, Korean cars, American cars, etc., but the overall driving experience of the vehicle is better.

It means that the car has two sets of clutch volts, and the two sets of clutches will work at the same time. The failure rate of the dual-clutch gearbox is relatively high, and then the cost of maintenance is also relatively high, and the torque is seriously insufficient when running at low speed, and the frustration is very strong; There are more disadvantages than advantages, so people are reluctant to buy.

It refers to a type of transmission, and the disadvantage is that the cost is relatively high and the maintenance is more complicated, so few people buy it.

It refers to the gearbox with two clutches, and the failure rate will be relatively high, which will sometimes increase the cost of maintenance, and there will be a situation of insufficient torque. This gearbox is very expensive and will cost a lot of money, so few people buy it.

Because this gearbox is more complicated and more expensive to repair, which is also its disadvantage, it is a more common transmission.

Dual-clutch transmissions are prone to overheating and failure, such as dry dual-clutch transmissions, and better yet, wet dual-clutches, which are generally used in mid-to-high-end models. Domestic car companies themselves have a certain experience and heritage in manufacturing manual transmissions, and many parts can be made of domestic products, and the cost is relatively low, so the dual-clutch with low threshold and low cost is a very good choice.

In order to grasp the initiative and not be stuck, many domestic brands such as Great Wall, Changan, Geely, etc. have developed their own dual-clutch gearboxes, and the state has also vigorously supported the research and development of dual-clutch transmissions by independent brands. With the advancement of technology and tuning, the dual-clutch transmission has also been optimized in terms of stability, and the driving experience is also ok, without giving people particularly obvious frustration. The acceptance of dual-clutch transmissions is also increasing.

Although the dual-clutch transmission is not very good, it gives people a very comfortable feeling in driving, and the car with dual-clutch transmission is not very high.

Because of the characteristics of fast shift speed and low fuel consumption, many people are still willing to buy a car with a dual-clutch transmission. The reason why it is said that the dual-clutch transmission is bad is that the clutch and electromechanical control unit of the dual-clutch transmission are easily damaged.

The dual clutch is hot, low-speed frustration, and the transmission is damaged a lot. So during that time, many people were choosing the manual automatic model of the Passat. The problem at the time was that the dual-clutch transmission used by the Passat was a dry dual-clutch.

The downside of a dry dual clutch is the local frustration and heat. Nowadays there are many kinds of transmissions, among which the automatic variable box is CVT, and the 6AT dual-clutch transmission is more common. 6at As we all know, we often talk about automatic transmissions, and previous automatic transmission cars mostly used this variable box, <>

The disadvantage of this variable box is that fuel consumption is difficult to control. In recent years, Japanese cars have preferred CVT variable boxes mainly for smooth gear shifting and fuel economy. When it comes to fuel economy, the most fuel-efficient variable box has to be a manual transmission.

To put it bluntly, the dual clutch is made on the basis of a manual variable box with a set of clutches. The advantage is low cost and fuel saving. But the dual clutch is available in dry and wet versions.

The early Volkswagen's dry dual clutch pitted a lot of people. What shift frustrations, overheating of the variable box, power loss and so on. So it leaves a shadow.

When it comes to dual clutches, it's unreliable. A lot of people haven't been exposed to the new wet dual clutch, so they're naturally stuck on the concept, so they won't like to take a guess at it.

Now the wet dual clutch has been slowly accepted by everyone, and the failure rate is low, but if individual manufacturers do not adjust well, there will still be setbacks. The advantages of a dual-clutch transmission are fast shifts, less frustration, and good fuel economy. For a sporty car, it's cool to pair it with a dual clutch.

The most representative are the Volkswagen Golf and the Porsche Macan. It is said that the dual clutch is not good and we don't know how to fix it, so we won't take risks if we don't. Second, the budget is limited.

Hundreds of thousands of dual-clutch cars don't break, right!No money!About 100,000 people bought it.

I don't have a bottom in my heart!Thirdly, blow all day long to save fuel and be stable. Is this useless?

What do you care about when buying a car?Failure rate, ease of driving, safety, comfort and appearance level!Now that I've bought a car, I'm not going to just drink water, okay?

Can you save a car in 10 years? As for smoothness, it has more to do with the level of driving, well! No matter how good you do, people who can't drive will drive windmills!

So I bought the at self-priming multi-link, at least saving on snacks, we never raced, started meat, accelerated slowly, I thought there was no problem, not racing! Therefore, for a dual-clutch transmission, there is no problem with the wet transmission, just check whether the model is a wet dual-clutch or a dry dual-clutch. So, when it comes to dual clutches, fear not.

As long as you know, it's more acceptable.
