Chen Geng felt that his expression at the moment must be very strange and funny. Pen, fun, and www.biquge.info

Not only Chen Geng's expression was like this, but Lin Shuyao, Xie Minsheng, Jia Tingliang, and Du Sirui on the side ...... All those who knew Ma Lao's status in the domestic aviation industry had no better expression than Chen Geng.

Old man Ma, the leader of the 708 project, now said that he would come to Runhua Industry to help do some preliminary work.

Fortunately, Chen Geng finally saw the wind and waves, and after a short shock, he hurriedly said: "Ma Lao, you can kill me with your words, you are the Taishan Beidou of our national aviation industry, we can't invite us with lanterns, you are willing to guide us, it is our great honor......"

Mr. Ma suddenly interrupted Chen Geng's words and said, "You kid won't give me a 'but', right?" ”

As soon as Old Man Ma said this, a group of unscrupulous old men who were at least 58 years old suddenly burst into laughter.

Chen Geng was stunned for a moment, shook his head and smiled bitterly, well, it can't be said to be a bitter smile, what an honor it is to be ridiculed by Old Man Ma?

"Of course not," Chen Geng hurriedly waved his hand and said: "Old man, you are willing to guide us, that is our great honor, well, we Runhua Industry is going to set up a 'commercial aircraft technology research group', I don't know if Ma Lao is willing to come to our seminar group as a leader?" ”

The corners of Lin Shuyao's mouth twitched slightly: Commercial aircraft technology research group? You just verbally formed this group, right? It's hard for you to come up with a way so quickly.

After a pause, Chen Geng looked at the group of old men and ladies in front of him with an average age of more than 62 years old, but all of them were Taishan Beidou level old men and ladies in the domestic aviation industry, and finally his eyes fell on the old man Cheng from time to time, and said: "Cheng Lao ......"

Without waiting for Chen Geng to finish speaking, the old gentleman Cheng smiled from time to time: "Anyway, I should retire, it's better to come down as soon as possible to make way for others, I heard that Xiao Chen, you have a lot of comrades from the demon capital here?" That's a good feeling......"

"Count me in."

"How can this kind of thing be without me?"

"I still have teaching tasks, but it doesn't matter, we can call if there is anything."

"I won't be able to get out for a while, but Xiao Chen, if you have any aerodynamic problems, just call me ......"

…………

Looking at these smiling old men who have devoted themselves to the aviation industry of the republic, and at this moment they have supported the work of Runhua Industry in their own way, Chen Geng's eyes suddenly turned red, and his nose was a little sour......

There was no superfluous movement, Chen Geng just folded his hands, and then bowed deeply to the old men: "Thank you, thank you." ”

This "thank you" is unprecedentedly sincere in what Chen Geng said.

Xie Minsheng's eyes were already red, and Lin Shuyao's tears kept falling......

――――――――――――――――――――――――

"Jun Chen, can I ask you a question?" Shinichiro Tanaka politely said to Chen Gengdao.

"Of course, you can ask whatever the problem is." Chen Geng attaches great importance to the arrival of Shinichiro Tanaka, and when he receives a call from Shinichiro Tanaka to visit, Chen Geng knows that the balance in Shinichiro Tanaka's heart has been tilted towards the side of Runhua Industry.

First of all, he bowed politely to Chen Geng, and then Shinichiro Tanaka asked: "Chen Jun, does Runhua Industry have any plans to develop automatic transmissions?" ”

"Of course!" Chen Geng said without hesitation: "Runhua Industry has been vigorously developing its own automatic transmission technology, we have completed the preparation of hydraulic torque converter and hydraulic coupling under laboratory conditions, the maximum torque that can withstand 600 Nm, optimistic estimates, within two years Runhua Industrial can come up with the first 4AT engineering prototype." ”

Shinichiro Tanaka was suddenly moved!

Although the German ZF company has launched a 5AT automatic transmission with 5 forward gears, 4AT is still a symbol of high-end automatic transmission, and the models equipped with 5AT automatic transmissions are basically the flagship models of Mercedes-Benz S-Class luxury brands, while in Japan, even the top flagship models can only be equipped with 4AT, such as Toyota's LexusLS400 that is ready to impact the market pattern of the world's luxury car brands. It is equipped with a 4AT automatic transmission provided by Aisin Seiki, and now, the Chinese are ready to come up with the first 4AT engineering prototype in 2 years?

It's incredible!

However, thinking that the Chinese have solved the problem of the material and processing technology of the torque converter with the technical support of the Soviets, then all that remains is the arrangement of the gear set and pipelines and oil circuits, and these things will always find a suitable layout scheme as long as they work hard to explore.

Chen Geng continued: "Automatic transmission technology is indeed difficult, the design and processing accuracy, process level requirements are very high, but the basic gear layout structure is nothing more than the Simpson scheme and Lavina scheme, these two basic gear layout schemes are not protected by patents, there are no intellectual property barriers, everyone can do it, only some special, special structures will have patent protection, such as Mr. Tanaka, where you were previously located Aisin Seiki and Germany ZF, Runhua Industry chose the Simpson structure, and now the progress is very fast. ”

From the mid-90s to almost 20 years later, foreign automobile manufacturers and their "partners" in China have been constantly instilling a concept in everyone: automatic transmission is difficult, very difficult, very high technical content, we Chinese in materials, technology, electronic technology, software programming and other basic aspects and high-tech aspects have an all-round gap with the West, China wants to make its own automatic transmission, let alone 20 years, It may not be possible to succeed in 50 years, this is not something that can be changed by the efforts of a certain company or a few research institutions, and there are too many places where we need to make up for it......

What Chen Geng wants to say is: bullshit!

Although the automatic transmission is indeed a very advanced thing, but the basic gear layout structure of the automatic transmission was patented as early as the 20s, these two typical gear layout structures are named after the inventors, respectively called Simpson structure and Lavina structure, now almost all automatic transmissions in the world are in these two basic structures to make their own improvements, the formation of their own patents, but the patents of these two structures have long expired, everyone can use them.

If you are careful, you will find that domestic manufacturers engaged in the manufacture of hydraulic torque converters and hydraulic couplings abound, and enterprises engaged in the hydraulic industry also grasp a handful, even if it is the most difficult automatic transmission basic software design and shift logic calibration of these, with the domestic level of software, it will not be impossible to do, and it is nothing more than a big data collection.

What really affects the development of the domestic automatic transmission industry is one place: cost!

Aisin Seiki and ZF, which are automatic transmission companies sold all over the world, have an annual production capacity of millions of units, which is tens of millions of units, how strong is the premium ability in front of spare parts suppliers? How strong is the cost amortization power?

As for you, do you have the "bargaining power" in front of the spare parts suppliers when you produce thousands of units a year -- maybe you can't sell them? People may think that your orders are too small and troublesome and are unwilling to supply you.

In the end, you produce an automatic gearbox at a cost of 50,000 yuan, and giants like Aisin Seiki and ZF produce an automatic gearbox with a cost of more than 10,000 yuan, which means that if your car is equipped with its own automatic transmission, the cost is more than 30,000 yuan higher than others, and you have a car of less than 100,000 yuan, and the cost is more than 30,000 yuan, why should you compete with others? Do you want to live?

Shaking his head, Chen Geng retracted his thoughts and said to Shinichiro Tanaka: "When the time comes, Runhua Industry will implement the division system, and the powertrain and spare parts will continue to be open to the outside world as now, and we hope to become one of the world's most famous automatic transmission suppliers." ”

This is to listen to himself, Tanaka Shinichiro understands that the meaning of Chen Geng's words is to tell himself that after the implementation of the business division system in the future, he will be the top person in charge of the power system assembly and spare parts division.

This promise is not unimportant, Tanaka Shinichiro no longer hesitated, bowed slightly, and said to Chen Geng: "Chen Jun, it is my honor to be able to join Runhua Industry, and I would like to ask you to take care of me in the future." ”

Finally made sense of this guy, Chen Geng breathed a sigh of relief, but his heart suddenly moved: he suddenly thought of another thing: "Mr. Tanaka, in addition to this 4AT, we have completed the development of the 6AT automatic transmission, in addition, I personally have designed a new automatic transmission, which is a 'fuel-electric hybrid system' and the design of the infinitely variable automatic transmission, I call it E-CVT." ”

“e―cvt？” Shinichiro Tanaka said movingly.

I don't know what this E-CVT is all about, but it sounds amazing.

"That's right, we all know that the fossil energy on the earth is limited, in the foreseeable time, the world's governments will inevitably take a variety of administrative and mandatory measures to vigorously promote energy conservation and emission reduction, in order to reduce emissions, the purpose of my design of this hybrid system is very simple: is to create an ultra-low fuel consumption, ultra-low emission car, and according to my calculations, using my design, the level of fuel consumption can be greatly reduced, urban fuel consumption and 100 kilometers of constant speed fuel consumption can be done 100 kilometers or so 5 liters, And driving in the city, you can do more and more fuel-efficient. ”

"It can't be!" Shinichiro Tanaka stood up almost subconsciously, and Chen Geng's words completely subverted his knowledge structure: "How can there be a car that is more congested and more fuel-efficient?" (To be continued.) )
