After BYD thought clearly about the impact of the dual-clutch gearbox, it officially announced the news of the first dual-clutch gearbox developed by its own domestic brand on the official WeChat.

Originally, Nanshan Group stopped, and with the efforts of Volkswagen, Chuncheng Automobile Group, Modu Automobile Group, etc., the topic of Volkswagen DSG slowly cooled.

But now a Weibo of BYD has raised the topic of DSG again.

This made Vondel very depressed.

"Our team of engineers made a preliminary analysis and thought that BYD's dual-clutch gearbox was definitely inferior to ours."

"Although the structure of the dual-clutch gearbox is simpler than that of the AT gearbox, the threshold is relatively low, and from the structural point of view, it is a combination of two manual gearboxes."

"And dual-clutch transmissions don't have as much patent protection as AT transmissions."

"However, at the moment of starting, it is a matter of learning to control the clutch to connect the power. If you engage too quickly, you can easily get frustrated, and the clutch wears out a lot. ”

"If the engagement is slow, the clutch life will be a little longer, but the speed of the car can't keep up with the speed, and the subjective feeling that the car will move slowly for half a beat, which is very unnatural, and it will be very painful to follow the car in a traffic jam."

"Our company has studied for so many years and has not completely solved this point, and I don't believe that BYD can do it so easily."

Dr. Hassan is the quality director of Modu Volkswagen, and he was in charge of the transmission business before, so after Vondel saw the news that BYD had developed a dual-clutch transmission, he asked Hassan to confirm it.

"I see BYD's gearbox advertised that it shifts quickly, what do you think of this?"

Vondel felt the need to get to the bottom of the situation and not get into trouble again.

"Fast gear shifting can be said to be the innate advantage of dual-clutch transmission, and our DSG is to promote fast gear shifts and uninterrupted power as the main selling points, and it has quickly been recognized by the automotive media and people who love driving all over the world."

"But the faster the dual-clutch gearbox shifts, the more wear pressure the internal components will be, and the less durability will be, which is a trade-off."

"And in order to achieve accurate gear shifting, it needs to accumulate data through a large number of road tests, and according to road conditions and driver habits, the software is written to match the optimal shift logic."

"This requires automobile companies to have rich data accumulation, and manufacturers with long experience in car manufacturing will have more advantages."

"BYD's own automatic transmission is a big gap, lack of talent and lack of data, directly to the dual-clutch stage, obviously impossible to do better than us."

"If Nanshan Gearbox comes up with a dual-clutch transmission, they have a lot of experience in the production of AT gearboxes, but it may pose a threat to us."

Hassan's judgment made Vonder breathe a sigh of relief.

It is difficult enough for a Nanshan group to appear in Huaxia, if this BYD is also so fierce, then the future will really not be able to go on.

"Since you think BYD's dual-clutch is not very good, why do they want to abandon the AT gearbox of Nanshan transmission?"

Vondel asked a question that left Hassan a little speechless.

Why did Volkswagen abandon the AT transmission and choose to develop its own dual-clutch transmission?

The situation faced by BYD is actually similar to that of Volkswagen, right?

Although the products of Nanshan gearbox are good, there are so many independent brands in use.

When the production capacity is insufficient, can BYD get the supply first?

This is a big problem.

In addition, the overall architecture of the dual-clutch transmission is somewhat similar to that of the manual transmission, except that there is an additional clutch assembly and shift actuator compared to the manual transmission.

Overall, the dual-clutch transmission has a simple structure, and the cost of the dual-clutch transmission is the lowest among all automatic transmissions.

Then there is the working principle of the dual-clutch gearbox is somewhat similar to that of manual transmission vehicles, compared with the AT gearbox, it has the characteristics of high transmission efficiency and less energy loss.

This can reduce fuel consumption to a certain extent.

As if feeling Hassan's resentment, Vondell changed the topic a little embarrassed and said: "Since BYD's dual-clutch is not a threat, we don't have to deal with it." ”

"Otherwise, the popularity of DSG will go up again, and it won't be good for us."

Volkswagen, which has suffered a big loss, now wants to see DSG media from all walks of life.

Whether it's good or bad, don't want to see it.

At this time, cold treatment, giving Volkswagen a few months of buffer time is the best.

However, Vondel wants to calm down, but the competitors don't.

Just after the release of BYD's dual-clutch gearbox, Nanshan Group also officially held a meeting for this matter.

"Mr. Cao, all domestic independent brands are using our AT and MT gearboxes."

"And most of them still use our engines, in this case, everyone's powertrain homogeneity is more obvious."

"Car companies like BYD and Chery, which want to hit the first place in the industry, want to develop their own engines and gearboxes."

"BYD already had its own engine before, and now it's not a very strange thing to come out with a gearbox."

Ji Hua didn't seem so irritable because of BYD's actions.

This day was something that had been expected for a long time.

And it is certain that BYD will not be the last company to produce its own gearbox.

However, there is also a big difference between a gearbox and a gearbox.

"What Mr. Ji said makes sense, the dual-clutch gearbox appeared very early, and the relevant patents have basically passed the protection period."

"Coupled with the simple structure, the cost is relatively low."

"It is not surprising that BYD chose to take a technical direction with Volkswagen."

"But I think it's time for their sales to start going downhill when their new models start to have their own engines and transmissions on a large scale."

"Don't look at last year, they had the fourth place in the country, and the sales reached 700,000."

"But it's likely that the next 10 years will be their peak."

"In the future, there will be more models, and maybe the sales will not be as good as now."

Zeng Tingting was not very nervous.

The technical level of Nanshan gearbox is not so easy to catch up.

Even the powerful Volkswagen has made a bunch of bad things out of DSG, and if BYD can do it so easily, she doesn't believe it.

If BYD had gone to do the MT gearbox by itself, it might have done a good job.

However, now consumers do not look down on MT transmissions, and more than eighty percent of sales on the market are contributed by automatic transmission models.

"The possibility that Mr. Zeng said really exists."

"Even if 700,000 is not the peak, this year's sales are likely to be the peak in the next decade."

"BYD is still a dry clutch this time, which is more likely to have problems."

As a gearbox expert, Ji Hua naturally has some research on dual clutches.

"This dry clutch gearbox is cheap enough, so BYD is ready to focus on dry clutch gearboxes like Volkswagen."

Zeng Tingting can be said to have seen BYD's ideas very thoroughly.

"That's right, the dry clutch gearbox doesn't need a special oil pump, and it's a much simpler structure."

"However, the heat dissipation of the dry dual clutch completely depends on air cooling, that is, the air intakes from a small ventilation hole, but if the speed does not come, there will be sufficient air cooling, so the clutch is easy to high temperature, and the service life will be relatively short."

"It can be said that cars with dry dual-clutch transmissions are only suitable for use on non-congested roads, but who can drive on smooth roads every day, except for rural and rural car users?"

Ji Hua spread his hands, looking completely disdainful of the dry clutch gearbox.

"In addition, the air vents can get water if they can get air, and of course the air with high humidity will also get in."

"This creates two problems, one is the clutch is rusty, and the other is the flywheel is rusty."

"Rust on the clutch will produce abnormal noise, and the flywheel is no exception, the flywheel is the power output end of the engine, which belongs to the engine, and the clutch presses the flywheel to get power."

"Therefore, some owners who use their cars in areas where there is a lot of rain and the road is prone to water accumulation are often due to the continuous abnormal noise caused by rust."

"In order to reduce costs, BYD will definitely fall in the end in order to get rid of its dependence on us."

After listening to Ji Hua's words, Zeng Tingting added next to her: "I heard that Great Wall Motors and Geely Automobile have their own ideas for developing dual-clutch transmissions. ”

"If BYD can fall on the dual-clutch gearbox, maybe other independent brands can sober up and obediently use our gearbox in the future."

As the world's leading transmission company, the product quality of Nanshan Transmission is beyond doubt.

It can be said that it is very rare that there has not been a large-scale defect of quality for so many years.

However, it is precisely because the products of Nanshan gearbox are so excellent that some people feel that the threshold of the gearbox does not seem to be so high.

I always want to challenge myself.

Finally, after hitting the wall, you can wake up.

"Since everyone thinks that the gearbox made by BYD is not threatening, it can even help us make some brands sober up."

"Then let them go, and we don't have to show any special opinions."

Ji Hua and Zeng Ting both said that, and Cao Yang naturally stopped being entangled.

BYD itself is inflated, and if you want to toss, then toss it.

Just like Chery Automobile, what high-end brand Qoros did well, and in the end it was a mess.

It is better to honestly develop low-end sedans and do a good job in this market, but it can bring surprises to people.

"Mr. Cao, although BYD's own gearbox has a very small impact on us, I think we can take this opportunity to launch our CVT gearbox."

"In this way, everyone will think that we are responding to BYD with a CVT gearbox, which is cheaper than an AT gearbox, because BYD has developed a gearbox."

As soon as Ji Hua said this, Cao Yang couldn't help but ask: "Has the problem of CVT steel belt been solved?" ”

Nanshan gearbox research CVT is not a day or two, the reason why it has not been officially launched into the market, the main reason is that the problem of steel belt has not been completely solved.

In today's CVTs, the key structure is on the tapered wheel and the steel belt or steel chain.

Both technologies are patented, with the steel belt in the hands of Bosch and the steel chain in the hands of Schaeffler.

If you want to bypass other people's patents, and also ensure the performance of steel belts or steel chains, it is a test of Nanshan gearbox.

In the end, Nanshan gearbox chose the steel belt structure as the breakthrough point, and Jihua and Nanshan Special Steel did many tests before finally finding a suitable steel belt.

Now that it has basically reached the level of mass production, it is natural to launch it at the right time.

"Yes, it's been resolved."

"In the past, if you asked Bosch to buy steel belts, they would sell for more than 800 yuan, which is simply a money grab."

"Now that we produce it ourselves, the cost of a steel belt is less than 200 yuan."

Nanshan Group has a very direct competitive relationship with Bosch.

Therefore, its own CVT gearbox must not use Bosch steel belts.

Schaeffler's situation is similar, and the competition in the field of bearings has reached a fever pitch.

Therefore, even if the cost is not considered, from the perspective of supply security, the steel belt needs to be produced by Nanshan Group itself.

Even if this problem caused the start of production of CVTs to be delayed by more than a year.

"Now that the CVT technology has matured, let's officially release it to the public."

"At that time, small CVTs, medium CVTs and large CVTs will be released at the same time, giving various car companies more choices."

"They always think our 6AT is too expensive."

A CVT gearbox is much simpler than a 6AT gearbox, requiring only a steel belt and two variable diameter moving wheels to achieve continuously variable transmission, while a 6AT gearbox requires complex components such as torque converters, planetary gear sets, clutches, and electronic control systems.

Therefore, the production cost of CVT is cheaper than that of 6AT, which can better meet the needs of some low-end models of independent brands.

And the CVT transmission can bring better ride and fuel economy, which is also a big advantage.

Of course, this is only compared to the 6AT.

If you go with 8AT and 10AT, you don't necessarily have these advantages.

Of course, there are advantages, and there are naturally disadvantages.

For example, the power response is relatively slow.

Since the CVT transmission does not have a fixed gear, the engine speed will increase and the vehicle will not accelerate significantly when accelerating or overtaking, which is called the rubber band effect.

While some high-level CVT transmissions can improve this problem by simulating gears or adding gears, they still can't compare to 6-speed automatic transmissions.

Then there is the CVT gearbox, which cannot carry high torque.

Since the CVT transmission mainly relies on the steel belt to transmit power, it is easy to cause the steel belt to slip or break when subjected to large torque.

Therefore, CVT transmissions are generally not suitable for large-displacement or high-power vehicles.

After Nanshan Transmission has a CVT, it will be able to focus on the combination of AT+CVT in the future, and it will definitely be able to completely blow Volkswagen's DSG.

Not to mention BYD's dual-clutch.

……

Nanshan Group unified its opinions internally, and the official Weibo of Nanshan Gearbox and Nanshan Group naturally quickly officially released the promotional video of CVT gearbox.

As the largest transmission company in China, Nanshan Transmission released CVT, which has attracted great attention in the industry.

Especially Volkswagen and BYD Auto, they are more sensitive to this matter.

"Mr. Wang, I feel that this move of Nanshan gearbox is aimed at our dual-clutch gearbox."

"In the past, many brands complained that the price of Nanshan transmission was too expensive, and now a cheaper CVT has been launched, which can directly suppress our dual-clutch transmission."

After Liang Chuanqing saw the news of the CVT of the Nanshan gearbox, he came to Wang Fu's office as soon as possible.

He felt that this matter still needed to be taken seriously.

In case the Nanshan gearbox has other counter-attacking maneuvers, it will be troublesome.

After all, BYD's current models are all products that use Nanshan gearbox.

As long as the other party finds a reason casually, saying that the supply is not available, then BYD's sales this year may be cut in half.

After all, even if their own dual-clutch gearbox is developed, it will need some matching development to be mounted.

If you load the truck in a hurry, there will inevitably be various problems in the end.

This is a situation that Liang Chuanqing does not want to see.

"Nanshan gearbox has not had any new products come out in the past two years, and now the CVT is released, it seems that they are engaged in CVT in the past two years."

"However, the fact that there is no movement on the Nanshan gearbox is what worries people."

"They're releasing a CVT gearbox at this time, and I'm not worried."

When Wang Fu said this, Liang Chuanqing was a little confused.

What does that mean?

As if feeling Liang Chuanqing's confusion, Wang Fu further explained: "With the relationship between the two of us, Nanshan Group will not easily resort to the trick of restricting supply. ”

"But our gearbox does have a bad head, so people also need to make a little bit of a move."

"Now the release of a new CVT transmission can be regarded as a response to the Nanshan transmission."

"With this response, it basically means that Nanshan Group will not do anything specifically against us."

Hearing Wang Fu say this, Liang Chuanqing breathed a sigh of relief.

With the size of Nanshan Group, if you want to do something against BYD, it will be really a trouble.

However, BYD is relieved, but Volkswagen has no way to rest assured.

"Vondel, I think Nanshan Group's release of CVT this time is aimed at our DSG."

"It's just that this time people are attacking from the front, and they don't make small moves."

"It's hard for us to say anything about this kind of attack."

Strauss was a little depressed and talked to Vondel.

Volkswagen tried everything to reduce the heat of DSG, but after a while, BYD released a dual-clutch gearbox, and everyone wanted to take out Volkswagen's DSG for comparison, and then the heat couldn't go down.

Within two days, Nanshan Transmission released a new CVT product.

This means that the gearbox industry has become lively all of a sudden.

It's all lively, how can the popularity of DSG be low?

After all, whether it is BYD's dual-clutch gearbox or the CVT of Nanshan gearbox, all kinds of media can't help but compare with each other.

Even many car companies will begin to understand the advantages and disadvantages of CVT, and consider which models they will use CVT transmissions in the future.

"Nanshan Gearbox's current AT+CVT strategy is very lethal."

"In the field of AT, their 6AT, 8AT, and 10AT are all very classic existences, and they have left a very good impression on everyone."

"The CVT that is being made now, everyone will subconsciously think that the quality is good."

"In addition, the price of CVT is cheaper than AT, and it is estimated that more car companies will consider buying products from Nanshan transmission in the future."

Vondel was a little helpless.

He felt like he had worked hard, but there was always something unplanned.

As far as the current DSG is concerned, he doesn't dare to compare it with other Nanshan gearboxes.

But just because they don't compare doesn't mean that the media doesn't compare either.

"So the Nanshan Group is a scourge."

"In the future, we have to find a way to get the United States to give more sanctions to the Nanshan Group, otherwise our life in China will not be easy."

In his heart, he couldn't help but think that the idea of why the United States didn't directly sanction the Nanshan Group came out.

"Nanshan Group is in the limelight, let's avoid it first."

"After this limelight passes, I will think of other ways."

"Huaxia is so big, there are always some people whose news will attract everyone's attention."

Vondel was very reluctant to choose to be a shrunken turtle.

The situation is stronger than people, and if it continues to stir up the topic of CVT and DSG comparison, Volkswagen may not be able to gain much in the end.

On the contrary, the quality problem of DSG will be raised again.

This is a situation that Vondel very much does not want to see.

However, Volkswagen is an ostrich, and other car companies are different.

In particular, Changan Automobile, which has never planned to develop its own transmission, was very active in contacting Changan Automobile after seeing the CVT, hoping that Changan Automobile's new model would be the first car equipped with a CVT with Nanshan transmission.

This will certainly be beneficial for future publicity.

"Mr. Yi, the price of small CVT can be about the same level as 4MT, which is basically the lowest price in the industry."

"A mid-size CVT is about the same price as a 5MT, while a large CVT is about the same as a 6MT."

"It can be said that any CVT product is cheaper than the price of a 6AT."

"If Changan Automobile is willing to be equipped with a CVT, you can communicate with the Nanshan transmission and Nanshan engine, and we can provide you with the best combination."

Except for the mini-car, Changan Automobile's other passenger cars use Nanshan Group's engines and transmissions.

In this way, it is convenient for the engine to match the gearbox.

Because Nanshan Group directly helped match it.

With a few simple bracket changes, a CVT-equipped model will be available this year.

At this speed, it is obviously still very good.
