This lightweighting is really impressive. The body frame in front of him is obviously the frame of the Eado that he first developed. If he looked at it from another body frame, he would have thought it was the system that Audi later used.

Woolen cloth!

You must know that Audi, which has been shopping for treasures in China for many years, is actually not close to kindness at all. But compared with Mercedes-Benz and BMW, at least they are not so stupid in terms of pricing. Coupled with the demonstration effect of official cars, Audi will soon

It has earned the reputation as a people-friendly car among luxury cars.

Therefore, in the past ten years or so, Audi has always been outstanding in China's mid-to-high-end luxury car market, and relying on such capital accumulation, they have also madly increased their investment in research and development, and after a few years, gradually

While it is getting closer to Mercedes-Benz and BMW, it even has the intention to gradually leave Mercedes-Benz and BMW behind.

At that time, Mercedes-Benz and BMW gradually understood the importance of the Chinese market and began to cut prices crazily and launch low-end cars in the Chinese market. However, at that time, Audi had already become one of the high-end luxury cars in the Chinese market.

The big brother.

The technology developed by Audi later not only made breakthroughs in the engine, but also had a very important point, which was that it was ahead of Mercedes-Benz and BMW in terms of lightweighting the body.

In 2011, Audi has completely resurrected in the high-end luxury car market. Not only is it better in China, it is not as good as Mercedes-Benz or BMW in the entire world.

The main reason is that they have already caught up in terms of technology.

The Audi a8l, a luxury car they launched that year, was even more stunning and decisive once it was unveiled.

The high-end luxurious body and huge engine weigh only 189 kilograms, less than 200 kilograms. The super long and huge body only weighs 241 kilograms, but the rigidity and strength of the entire body are much higher than before.

Falling instead of rising.

Such data combined is enough to give the Audi a8l the upper hand when facing BMW's 7 Series and Mercedes-Benz's S-Class.

The lightweight body not only makes the Audi a8l more fuel-efficient than cars of the same class, with a fuel consumption of 9.5 liters per 100 kilometers, it also allows this car to easily complete 0 to 100 kilometers in a few seconds.

accelerate.

This shows that the lightweight body of this car has a reborn effect on this car.

And now Wuyun has conquered all such lightweight technologies. How could this not make Jin Xiaoqiang feel unexpected joy?

Originally, he asked Peter to develop the lightweight technology for the new K-series. Originally, he planned to let Peter work together with Wu Yun to develop the lightweight technology for other models. Unexpectedly, Wu Yun is now the same.

After finishing this project, I really have to admire this woman!

"I did not complete the transformation project of the skeleton of Mr. Jin's car alone. I only provided the theory of bionics of modern animal skeleton mechanisms. In terms of the optimization of geometric parts and structures, Master Yang and Master Ding are both

They helped me a lot. Moreover, the special metallurgical materials used were all completed with the help of these two masters. It would definitely not be possible for me to do it alone."

Wu Yun also saw the admiration in Jin Xiaoqiang's eyes, but her years of rigorous work style in Germany also developed her character of never being greedy for merit.

"Look, Mr. Jin, we use extruded aluminum alloy parts for the red part of the body frame. This part accounts for 22% of the total white body. We use extruded aluminum for the blue part.

High-precision vacuum cast aluminum parts account for 35% of the body weight, and the other 35% are hydraulically formed aluminum alloy parts.

For the remaining 8%, high-strength alloy steel is used to ensure the strength and tensile resistance of important parts of the body. A total of 44 meters of laser-free splicing work was used for the entire vehicle.

By using seam welding technology, the weight of the entire car body can be reduced by 40%, while the strength is increased by 25%."

Wu Yun looked at the body-in-white in front of her and felt extremely proud in her heart. This was also the first time when she came to Huayang Dynamics that she did not work step by step according to Jin Xiaoqiang's guidance. It was completely developed by her.

A brand new technology.

When hearing Wu Yun's introduction, Jin Xiaoqiang felt a little dizzy. Why did Wu Yun's new technology sound so familiar?

Why does it feel so much like Audi's unique skill, asf, all-aluminum body technology?

In the current automobile era, many automakers’ so-called unique skills are actually found in other manufacturers. For example, the variable valve timing technology is called vtec in Honda, vvt-i in Toyota, and Mercedes-Benz.

BMW and Audi also have this kind of technology, but they use another name.

The same goes for other technologies. All major manufacturers have their own names for the same technologies.

But when it comes to unique skills, all major car manufacturers do have a few tricks up their sleeves.

Just like Audi a few years later, on their high-end luxury cars, there are two technologies that are indeed unique to them. One is their full-time four-wheel drive technology quattro, and the other is what he sees in front of him.

This is an all-aluminum body with ASF technology.

A few years later, luxury cars such as the Audi a8 and Audi q7 will be able to compete with the S-series and 7-series of Mercedes-Benz and BMW precisely because of the support of these two technologies.

And this ASF all-aluminum body technology has always been a unique skill of Audi. Even Mercedes-Benz and BMW have never used it on their bodies.

But I didn't expect that this technology would actually be born in Wu Yun's hands.

Before the Shanghai Auto Show, Wu Yun and the others had already started researching the topic of lightweighting the car body, but they never expected that they would be able to achieve such a breakthrough in about three months.

"Wuyun, what is the full name of this technology?"

"Is it the all-aluminum body technology?"

"Ahem, ahem, Wuyun's technique is not that simple to accomplish, right? How did you do it?"

Jin Xiaoqiang still felt some doubts.

"Hehe, actually, I have been studying this technology for a long time when I was at the Mercedes-Benz headquarters in Germany. At that time, it was said that people from Audi were also studying this technology. But the cost of this technology is too high, and we have studied it.

It took more than three years, but in the end Audi did not make it. Later, when people at the headquarters saw that this project was too expensive and labor-intensive, they canceled the project.

In fact, we had completed nearly 60% of the work on this project, but with the above sentence, the project was canceled. I felt it was a pity. At that time, this project was from scratch to the end.

I personally participated in it. Later, after I came to the company, I did not abandon this job. As long as I had time, I would study it quietly by myself.

Combination, hehe, for this purpose I also learned a lot of theories of animal bionics! There were not many models in the factory at that time, so I just practiced on the Escape. Unexpectedly, the more I practiced, the more proficient I became. Later

After seeing the car body cage structure and laser welding technology of the Enclave you designed, and later seeing the lightweight body design of the K series designed by Peter, I again

I got a lot of inspiration. After that, I didn’t have much work, and you didn’t assign any new tasks, so I happened to start this project with two masters, Yang Dingwei and Ding Weizhong. It was precisely because of my theoretical foundation, and the two

The master craftsman has expertise in material selection and metal smelting, so we were able to complete the technical research and development of this all-aluminum body within three months.”

Wu Yun explained to Jin Xiaoqiang with a smile. After listening to this, Jin Xiaoqiang finally understood that the matter of love was not accidental. It turned out that he had picked up a treasure. He happened to choose Wu Yun at the time, so he was like this.

breakthrough.

"But this all-aluminum body doesn't seem to be perfect, right?"

Jin Xiaoqiang looked at the flowing white body in front of him and always felt that something was wrong, but he couldn't remember it for a while.

"Well, in my opinion, there is only one shortcoming."

Wu Yun also looked at the white car in front of him, and then said to Jin Xiaoqiang.

"Oh? What is it?"

Jin Xiaoqiang asked again.

"That's because the cost is too high! A large area of ​​the vehicle's body is made of special aluminum alloy material. In order to achieve the same anti-torsion strength as before, very thick aluminum alloy is used in many places. This way

Although the weight is lighter, the cost is higher. And because many parts of the car body use special welding technology and processing technology, once the car is involved in an accident, when the metal of the car body is distorted, the cost of repairs will increase.

It’s also higher than the original ordinary materials.”

Wu Yun's explanation made Jin Xiaoqiang feel enlightened. No wonder other luxury high-end cars did not follow Audi's footsteps. It turns out that cost is also a big problem.

However, in China, such cost problems seem to be easier to solve. Although our technology costs cannot be reduced, our labor costs have always been lower than those in foreign countries. Regardless of the current Huayang Power's wages and benefits, they are very high.

, but if compared with foreign automobile factories, it seems that there is still a lot of difference. After all, there is an exchange rate there.

"Well, Wu Yun, please discuss with Master Yang. Let's not make all-aluminum bodies for low-end and mid-range models. We'll start with our Qoros models first and try to open up a breakthrough in high-end cars."

Wu Yun quickly understood what Jin Xiaoqiang meant. It is true that such technology would be better used in high-end luxury cars at the beginning. After all, people who can afford such a car are not short of money!!
