It's often your competitors who know you best.

There is generally nothing wrong with that.

In the same way, the people who know a product best are often their peers.

What is the situation of CVT, Yin Chuan is very clear.

Of course, from the change in the face of Zhang Wuchao, the president of Chery Automobile Research Institute who was sitting next to him, Yin Chuan also knew that his worries were definitely not superfluous.

Nanshan gearbox is so engaged, how can you live?

However, Ji Hua on the stage didn't know the psychological activities of everyone in the audience, but continued to introduce there.

"Some people may have doubts, although the transmission efficiency of the CVT of the Nanshan transmission is better than that of other competitors, it is also lower than that of the AT."

"Then why do you want to have such a gearbox?"

"Is it just for the sake of driving comfort?"

"Can't make sense, right? After all, the AT gearbox of Nanshan gearbox has always been very well tuned for driving smoothness. ”

"Actually, there are two main reasons."

Ji Hua paused and looked at the reactions of everyone around him.

Very good!

Everyone was interested.

"One is the cost, the other is the fuel consumption!"

"Not much to say about the cost, there are many VIPs from OEMs today, and everyone must feel that the price of AT is too expensive."

"MT is cheap, but it's not convenient."

"CVTs can really be convenient, cheap, and the key is fuel-efficient."

Obviously, the CVT market of Nanshan Transmission is aimed at low-end models.

High-end models will definitely not use CVTs.

"Then when it comes to fuel efficiency, everyone may have questions again."

"Transmission efficiency has decreased, shouldn't fuel consumption have increased?"

Ji Hua asked such a rhetorical question, and many people really couldn't help but raise questions.

Even Lin Jiayan and others like NetEase Auto Channel fell into the inertia of thinking for a moment.

"The CVT transmission is called the most fuel-efficient transmission, and it's certainly not because of the low transmission efficiency."

"On the contrary, it saves fuel consumption precisely because of its high efficiency."

"It may sound contradictory, but it's actually not that hard to understand."

"We need to know that transmission efficiency is only an indicator of the performance of the transmission system itself, and does not represent the performance of the entire car."

"The fuel consumption of a car depends on many factors, one of the most important is the working condition of the engine."

"The engine has an optimal operating range, which is the rev range in which it is capable of delivering maximum power and the best fuel economy."

"If the engine is running in this range, then the car will be able to achieve peak performance and fuel consumption."

"The CVT gearbox takes advantage of its infinitely variable speed characteristics, so that the engine always runs in the optimal working range."

"It has the freedom to adjust the gear ratio according to the driving conditions and the driver's intentions to match the engine output and the vehicle's needs."

"For example, when accelerating from the start, the CVT transmission can choose a large gear ratio, which makes the engine rev higher and output more torque and power."

"When cruising, the CVT transmission can choose a smaller gear ratio, which allows the engine to rev lower and output less torque and power, thereby reducing fuel consumption and emissions."

"In this way, the CVT transmission is able to achieve the best match between the engine and the vehicle, improving the efficiency and performance of the entire vehicle."

"On the other hand, AT and MT gearboxes are geared by a limited number of gears, each corresponding to a fixed gear ratio."

"This leads to a lack of flexibility and precision in the matching between the engine and the vehicle, and often the engine speed is too high or too low."

"So, although the CVT transmission is lower than the gear transmission in terms of transmission efficiency, it is much higher than the gear transmission in terms of engine and vehicle matching."

"Wait a while, we have specific products in the back exhibition hall to introduce you to some more specific parameters, so that you can have a more in-depth understanding of our CVT products."

The new product launch conference will definitely not introduce too many boring technologies there, so Ji Hua's words are basically to the point.

Then you move on to the next product.

There were so many people attending the meeting today, and Autohome even held a live broadcast at the same time, so the situation introduced by Ji Hua just now was naturally known by many other people who paid attention to this press conference.

For example, within Aisin, there was a group of people in the conference room to watch the live broadcast.

"President, CVT, sure enough, it's CVT."

"No matter how much they say, there's not much to say technically."

Okumura breathed a sigh of relief when he learned that the new technology released by Nanshan Transmission was a CVT.

CVT is not a high-tech, and even compared with 6AT, CVT does not have many advantages except for being more fuel-efficient and cheaper.

"Although there is not much to say in terms of technology, there may be a lot of things that people can say in terms of cost."

"According to our speculation, the average CVT is at least 20% cheaper than the 6AT."

"If the cost control is better, it is possible to reduce the cost by 30%."

"In this way, many customers of Nanshan gearbox, the cost pressure is not so great."

Yoshikawa was clearly aware of the impact that Nanzan Transmission's CVT would have on Aisin.

Originally, they also wanted to open up the market by establishing joint ventures with companies such as Geely and Yangcheng Automobile.

However, if the gearbox produced by the joint venture company is more expensive than the CVT on the market, then it is a very embarrassing choice for the joint venture party.

High-end models can continue to use 6ATs, but if entry-level models also use 6ATs, then the cost pressure will be very high, and the price will not be competitive.

The more entry-level the model, the more sensitive consumers are to the price.

In the same situation, the lower price will definitely sell better.

"We also have a CVT gearbox, but the transmission efficiency is not as high as 87%, but it is not bad."

"Why don't we also promote CVT to our customers in Huaxia?"

Okumura came up with a new idea.

However, Yoshikawa is not very optimistic about this matter, saying: "Toyota has not yet converted the transmission to CVT so quickly, and it is normal to wait for the next generation of models to start using CVT transmission." ”

"If we sell now, we can only use products produced from Dongying, and the price is not competitive."

"There is even a possibility that the price of a CVT will be higher than that of an AT."

"In this way, let alone expanding customers, it's good not to make wedding clothes for Nanshan gearbox."

Assists this kind of thing, Yoshikawa is definitely not willing to do.

They are going to hate Nanshan gearbox to death, how can they be willing to give them assists?

Therefore, if there are such concerns, Aisin will not consider promoting CVTs in China anytime soon.

"So what should we do?"

"Nanshan Transmission has launched three levels of CVT in one go, and it is estimated that car companies will soon start to adopt it."

"After all, although the automobile market in China is growing rapidly, the competitive pressure is also increasing."

"In this case, if the price of CVT is really advantageous, then it must be acceptable."

When Okumura said this, Yoshikawa was a little upset.

What to do?

I want to ask you!

"Don't discuss it yet, Nanshan Gearbox is going to announce the second transmission technology."

……

"Theoretically, the more gears an AT gearbox has, the more reasonable the division of gears, both for smooth shifting and better fuel economy."

"But it will also greatly increase the difficulty of gearbox research and development, some friends have said that the current 8AT is already the best product, and there is no interest in developing a higher-grade transmission for the time being."

"Our Nanshan Transmission is the first manufacturer to launch mass production of 8AT automatic transmission enterprises."

"But the pace of our technological progress never stands still because we are already ahead of our peers."

Although Ji Hua is a high-tech, he has also learned a little about Cao Yang's porcelain marketing methods.

Today is the new product launch conference of Nanshan Gearbox, and it is also the publicity meeting of Nanshan Gearbox.

Let everyone know that Nanshan Gearbox is a company that pursues excellence and advanced technology, and there is nothing bad about it.

Only by continuously introducing new products with high gold content can an enterprise continue to establish a high-tech image.

The current Nanshan gearbox undoubtedly has a certain image in this regard.

The next thing Ji Hua has to do is to strengthen it.

However, as soon as he said this, Aisin's group of people watching the live broadcast immediately became nervous in their hearts.

What are you afraid of!

The CVT that has just been released is a CVT, and everyone can breathe a sigh of relief.

But now looking at Ji Hua's appearance, it is obvious that he is going to release a gearbox with more gears than the 8AT.

9AT？

Finished!

In the next three years, Aisin will not be able to keep up with the pace of Nanshan gearbox.

Ji Hua on the stage didn't care about the mood of Aisin's gang, and continued:

"After the successful development of 8AT, we set up an internal research and development plan for 10AT, codenamed 10R80."

"10 stands for 10 forward gears, including 6 low-speed gears, 1 direct gear, and 3 overdrives, R for longitudinal rear-wheel drive or four-wheel drive, and 80 for 800Nm of torque."

"This 10AT automatic transmission uses four sets of planetary gears and six shift actuators, which combine 10 forward ratios and one reverse ratio."

Ji Hua didn't sell it, and soon announced the answer.

At this moment, there was a lot of discussion at the scene.

10AT！

The Nanshan gearbox directly skipped the 9AT and got the 10AT out.

That's awesome, isn't it?

Aisin, ZF and other transmission giants have not yet made any moves in this regard, and as a result, Nanshan Gearbox directly took out all the products.

The days of the gearbox industry are about to change!

"Our 10AT gearbox has been tested on the Star Journey and Star Sports Car."

"I've tested it myself, and the 10-speed automatic transmission provides the right gear ratio for the engine at different speeds, so that the engine always runs in the lower rev range."

"This reduces fuel consumption and noise, while also improving power output and acceleration."

"When we press the accelerator, the 10AT transmission can quickly jump gears to reduce the gear ratio, allowing the engine to ramp up to the maximum torque range, giving us a strong push back feeling."

"When we release the throttle, the 10AT transmission can upshift in time to improve the gear ratio, so that the engine speed is reduced to the lowest fuel consumption range, which brings us fuel saving effect."

"This 10AT is very advanced, it has a very tight gear ratio, and the gear ratio gap between each gear is very small."

"So in the process of daily driving, it is basically the logic of shifting gears, and the step-by-step shift is rarely used, mainly to make the gearbox reduce the speed less when changing gears, and maintain the maximum torque output of the engine at all times, so the models equipped with this 10AT can easily hang 10 gears at high speeds."

"Some people think that the 10AT is useless, and ordinary consumers can't drive it to that kind of working condition, so they can put it in the trash."

The more Ji Hua spoke, the more excited he became.

Since coming to Nanshan Gearbox, his life has begun to change dramatically.

Needless to say, the income has skyrocketed, and the social status has also improved a lot.

The main thing is that this sense of accomplishment is not at all comparable to what it used to be.

"Our 10AT gearbox can be mounted on both pickup trucks and high-performance sports cars."

"Each model has its own gear-shifting logic, for example, when used in sports cars, and the gear-shifting logic pursues faster gear shifts."

"In pickup trucks and large SUVs, fuel economy is more important, and the engine speed can be controlled at a lower level."

"Different software programs can be optimized for different vehicle types."

"Our 10A has four gears more than the 6-speed automatic, and a lot of people think it's going to get too bulky?"

"What I want to tell you is that there is no need to worry at all, it is very advanced, there are many units, but the weight is only about 1.81kg more than the 6AT."

"The overall structure is very compact. The overall size is almost the same as that of some competitors' 8AT. ”

Ji Hua once again threw out a bombshell message.

This further sets off the technological advancement of Nanshan gearbox.

After all, the more gears, the more difficult it is, and although the layout is compact, it is inevitable that the volume will become larger.

However, the Nanshan gearbox is about the same size as the 10AT and the 8AT, which is a little longer than the 6AT.

This is very technically difficult.

"The weight of the 10-speed automatic transmission has not increased significantly, mainly because the entire shape is made of aluminium, the overall bell alloy shell helps to reduce weight and increase rigidity, and even the bracket of the gearbox is made of aluminium. The monolithic gearbox does not have cast iron parts. ”

These things will soon be known to everyone, so there is nothing to hide.

"The 10R80 and this 10AT have not increased in size because of the increase in gears, which is more conducive to the installation and matching of existing vehicles."

"There is no need to redesign the gearbox arrangement, which minimizes changes in the vehicle interface, and can meet the needs of the vast majority of vehicle models."

At this time, Ji Hua almost said to the customers who were using the Nanshan gearbox 8AT, come and see, there are more advanced products now.

It doesn't need to be tossed to improve smoothness, reduce fuel consumption, and enhance the sense of technology.

Why don't you hurry up and pay for it?

"If there are more gears, the structure must be complicated? However, no, as I said earlier, this 10AT has 4 sets of planetary gear sets, that is, 10 gear ratios are combined. ”

"The 8AT gearboxes of some European friends also use 4 sets of planetary gear set structures."

"Our 10AT has six actuators, two brakes and four clutches."

"Compared with the five actuators of the 8AT gearbox of our European friends, our 10AT only has one more clutch."

Although he did not name him directly, everyone knew that Ji Hua was talking about ZF's 8AT.

So far, the most famous 8AT in the world is Nanshan Transmission, Aisin and ZF.

This made the people of ZF, who were also watching the live broadcast, feel very depressed.

Didn't the Nanzan gearbox always point the knife edge towards Aisin before?

Why did you suddenly pull me into the water?

I don't have any sense of presence on the side of Huaxia's own brand!

I'm no match for you!

"To improve fuel efficiency, our 10AT is equipped with a variable displacement fuel pump that adjusts the supply pressure according to the speed and load."

"It uses a lower viscosity transmission fluid, which requires a viscosity of 4.5 centipoise, further reducing mechanical friction and oil pump workload within the gearbox."

"To accommodate the start-stop function, an electric oil pump cools the inside of the gearbox when the engine is off, while the reservoir starts the vehicle faster."

"In order to extend the life of the transmission, this 10AT is equipped with a two-stage high-efficiency filter to filter out impurities in the transmission oil."

"As a result, the cost of changing the transmission fluid will increase significantly."

"In addition to the use of variable displacement oil pumps and low-viscosity transmission fluids, needle roller bearings are used instead of thrust washers, and even tiny springs are used to separate multi-plate clutches to reduce drag between clutches."

Although some of today's guests do not understand gearbox technology, in addition to some popular science introductions, Ji Hua must also come up with some introduction content that sounds technical.

It doesn't matter if some people don't understand.

I don't know how to do it!

That's what you want!

"At the same time, the torque converter is designed to be thinner and larger in diameter, with a diameter of 260 mm and a lock-up clutch."

"It also uses electronically controlled capacity clutch technology that adjusts the amount of slip during gear shifts to dampen engine vibrations for smoother running and transferring power."

"After this series of optimizations, we can achieve a simultaneous reduction in fuel consumption while improving the performance in all aspects."

"For the same car, just by replacing a gearbox, it is expected to save 3% ~ 8% of fuel."

"And we have two models, horizontal and longitudinal, to fully meet the needs of customers."

"Later, you can go to the back to take a look at the dismantling diagram of our 10AT, I believe it will bring you a lot of surprises."

Ji Hua saw the reactions of everyone in the audience in his eyes, and he was very satisfied.

That's what I want.

Be surprised!

The Nanshan gearbox is so powerful!

We are the first manufacturer in the world to mass-produce 8ATs.

Now we are the first manufacturer in the world to mass-produce 10AT.

Whether it's Aisin or ZF, are you okay?

Nanshan Group has always been very good at using the Internet.

For such an important technical conference today, it is natural that there are also personnel who will be arranged to act on the Internet.

【Nanshan Group 10AT launched】

This news, after Ji Hua completed his explanation, rushed to the hot search on Weibo.

And in various automotive media, there will soon be relevant news.

Whether it is Autohome or NetEase Auto Channel, they will first announce some quick comments or hot news.

Then slowly post more in-depth articles.

For ordinary netizens, the new product launch conference of Nanshan gearbox is a bit boring.

But they don't need to know that specifically.

They just need to know that 10AT is better than 8AT, and much better than 6AT.

As long as they know the very powerful Nanshan Group, its Nanshan transmission has come up with the world's first 10AT automatic transmission.

This gearbox is very advanced, more powerful than any other manufacturer in the industry.

"In 2008, Nanshan Group has won a record of 5 first prizes of the National Science and Technology Progress Award and 5 second prizes of the National Science and Technology Progress Award, how do I feel that Nanshan Group may complete new breakthroughs in 2009?"

"With the advent of this 10AT, ZF and Aisin are going to be nervous, right?"

"Awesome, my Nanshan Group!"

"Produced by Nanshan, it must be a high-quality product!"

"Before there was no Nanshan gearbox, it was very difficult to buy a 6AT in China, and I had to beg someone to sell it."

"Now not only 6AT has been used on a large scale in self-owned brand models, 8AT has also been used in models such as Xingchen Automobile, and now 10AT has also come out, happy!"

"You can come once a day for a new product launch like this!"

……

The various discussions have attracted some people outside the automotive industry.

Originally, Nanshan Group was out of the circle some time ago, and its popularity in China is very high.

Now I have come out with a world-leading 10AT, no matter whether I understand what 10AT means or not, many people are also discussing it in the penguin group.

Tieba and the BBS of various colleges and universities are also related news.

This kind of feeling that you don't need to spend any publicity costs, and a group of people take the initiative to help you publicize, which is really good.

At the press conference, Ji Hua had already led everyone to the exhibition hall behind the Great Hall.

Each booth has a dedicated technician who is there to introduce something that is not confidential.

For example, there is no problem with the shape characteristics of the parts, how to introduce them, and how to blow the water.

But what material is used for this part and how it is produced, this may not necessarily tell you.

Whether it is a CVT or a 10AT, all the parts above have been localized.

Chips included!

This is definitely a very big technological advancement!

Although the chips used in this kind of parts are chips with low technical content, they can be made in China, which is also a very remarkable existence.

As so many people began to enter the exhibition hall, various specific information about CVT and 10AT also spread.

Nanshan Gearbox also provided the official advertorial to the relevant automotive media in a timely manner.

As a result, the reactions of all the cows, ghosts, snakes and gods who pay attention to the Nanshan gearbox are also different.

Even the various car companies that visited the scene had different expressions.
