This lightweight is really powerful, the body skeleton in front of him is obviously the skeleton of the first one he developed, if you look at the body skeleton, he thought this was the system that Audi used later!

You must know that Audi, which has been Taobao for many years in the Tianyuan Dynasty, is actually not related to kindness at all, but compared with Mercedes-Benz and BMW, at least they are not so brain-dead in terms of pricing.

Therefore, in the past ten years, Audi has always been outstanding in the sales of high-end luxury cars in the middle and high-end luxury car market, and with such capital accumulation, they have also increased their investment in research and development, and after a few years, they have gradually shortened the distance with Mercedes-Benz and BMW, and even have the meaning of gradually leaving Mercedes-Benz BMW behind.

At that time, Mercedes-Benz BMW gradually understood the importance of the Tianyuan Dynasty market, and began to cut prices frantically in the Tianyuan Dynasty market, and launched low-end cars, but at that time, Audi had already become the big brother in the high-end luxury cars in the Tianyuan Dynasty market.

Later, the technology developed by Audi was not only a breakthrough in the engine, but also a very important point, that is, it was ahead of Mercedes-Benz and BMW in terms of lightweight of the body.

In 2011, Audi was completely resurrected in the high-end luxury car market, not only in the Tianyuan Dynasty, but even in the whole world, it does not have to be Mercedes-Benz BMW to be bad.

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

The Audi A8L, a luxury car they launched that year, made people feel amazing and decisive once it was unveiled.

The high-end luxury body, the huge V63.0TFSI engine, the total weight is only 1 (8) 9 kg, less than 200 kg, and the ultra-long and huge body is only 241 kg in weight, but the rigidity and strength of the whole body are not lower than before.

Taken together, such data is enough for the Audi A8L to have the upper hand in the face of 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 level, and can achieve a fuel consumption of 9.5L per 100 kilometers, but also allows this car to easily complete the acceleration from 0 to 100 kilometers in a few seconds.

It can be seen that the lightweight body of this car brings the general effect of removing the tire and changing the bone to this car.

And now that the dark clouds have overcome all such lightweight technologies, how can this not make Jin Xiaoqiang feel unexpectedly happy.

Originally, he asked Peter to develop the technology of using the body lightweight on the new K series, and he originally planned to let Peter work together with Wuyun to develop the lightweight technology of other models, but he didn't expect that now Wuyun actually completed this project alone, and he really has to be impressed by this woman!

"Mr. Jin's transformation project of this model skeleton is not completed by me alone, I just proposed the theory of modern animal skeleton structure bionics, and in terms of structural optimization of geometric parts, Master Yang and Master Ding have helped me a lot. And the special metallurgical materials used are also completed with the help of these two masters, and it will definitely not work on me alone. ”

The dark clouds also saw the appreciation in Jin Xiaoqiang's eyes, but the style of rigorous work in Germany for many years has also developed her character of never being greedy for merit.

"Mr. Jin, you see, the red part of the body skeleton, we use the aluminum alloy parts that are extruded and pressed, which accounts for 22% of the total amount of the body-in-white, and the blue part we use high-precision vacuum casting aluminum parts, which accounts for 35% of the weight of the body, and 35% of the part, we use hydroformed aluminum alloy parts, as for the remaining 8%, it is made of high-strength alloy steel to ensure the strength and tensile resistance of important parts of the body. A total of 44 meters of laser seamless welding technology was used for the splicing of the whole vehicle, so that the weight of the whole vehicle body was reduced by 40 percent compared with before, and the strength was increased by 25 percent compared with before. ”…,

Wuyun looked at the white body in front of her, and felt extremely proud in her heart, this is also the first time that she came to Huayang Power, and she did not work according to Jin Xiaoqiang's guidance step by step, and it was completely a new set of technology developed by her.

When he heard Wuyun's introduction, Jin Xiaoqiang only felt a little dizzy, how could this new technology of Wuyun sound so familiar?

How does it feel so much like Audi's unique, ASF, all-aluminum body technology?

In the current era of automobiles, many car manufacturers have so-called unique skills, in fact, where other manufacturers are also available, such as the variable valve timing technology, called VTEC in Honda, VVT-I in Toyota, and Mercedes-Benz, BMW, and Audi also have such technology, but it will be called another name.

The same is true for some other technologies, and major manufacturers have their own names for the same technology.

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

For example, a few years later, Audi had two technologies that were really unique to them in their high-end luxury cars, one was their full-time four-wheel drive technology Quattro, and the other was the ASF technology he saw in front of him, which was an all-aluminum body.

A few years later, luxury cars such as Audi A8 and Audi Q7 were able to compete with Mercedes-Benz BMW's S series and 7 series, and it was precisely because of the support of these two technologies.

And this set of ASF's all-aluminum body technology has always been a unique skill of Audi's broom, even Mercedes-Benz BMW, which has never been used on their body.

But I didn't expect that now this technology was actually born in the hands of dark clouds.

Before the Shanghai Auto Show, Wuyun had already begun to study the topic of body lightweight, but they never thought that they would be able to make such a breakthrough in about three months.

"Dark Clouds, what is the full name of this set of technologies?"

"It's all-aluminum body technology, huh?"

"Ahem, ahem, ahem...... Forehead...... The technology of Dark Cloud is not so simple to complete, how did you do it? ”

Jin Xiaoqiang still felt a little doubtful.

"Hee-hee, in fact, this set of technology, when I was in the headquarters of Mercedes-Benz in Germany, I have been studying it for a long time, and it is said that Audi people are also studying this set of technology. However, the cost of this set of technology was too high, and we studied it for more than three years, and in the end Audi did not make it, and then the people in the headquarters saw that the project was too expensive and manpower-consuming, so they canceled the project. In fact, at that time, we had completed nearly 60% of the work on this project, but the above sentence canceled this project, which I think is a pity. At that time, I was personally involved in this project from scratch to the end, and I did not leave this job after I came to the company, as long as I had time, I quietly researched and combined it myself, hehe, for this I also deliberately learned a lot of theories of animal bionics! At that time, there were not many models in the factory, so I practiced in Yidong, but I didn't expect to become more and more proficient, and then I got a lot of inspiration when I saw the body cage structure of the Enclave designed by you, as well as the laser welding technology, and then I saw the lightweight body design of the K series designed by Peter. After that, there was no work, and you didn't have any new tasks, so I happened to start this project with Yang Dingwei and Ding Weizhong. It is precisely because of my theoretical foundation and the expertise of the two masters in material selection and metal smelting that we were able to complete the technical development of this all-aluminum body in three months. ”

Wuyun explained to Jin Xiaoqiang with a smile, and after listening to it, Jin Xiaoqiang finally understood that the matter of feelings was not accidental, it turned out that he also picked up the treasure, and it was just when he chose Wuyun that there would be such a breakthrough today.

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

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

…,

"Well, at the moment, there is only one shortcoming."

Wuyun also looked at the white body in front of him, and then said to Jin Xiaoqiang.

"Oh? What is it? ”

Jin Xiaoqiang asked again.

"That's the cost is too high! The body of the whole vehicle is made of special aluminum alloy material in a large area, in order to achieve the same torsional strength as just now, so many places use aluminum alloy with very high thickness, so that although the weight is light, but the cost is high. And because many parts of the body use special welding technology and processing technology, so that once the car has an accident, when the metal of the body is twisted, the cost of maintenance is higher than the original ordinary materials. ”

The explanation of the dark clouds made Jin Xiaoqiang feel suddenly enlightened, no wonder other luxury high-end cars did not follow the pace of Audi later, it turned out that this cost was also a big problem.

However, in the Tianyuan Dynasty, such a cost problem seems to be easier to solve, although our technical costs can not be reduced, but our labor costs, but has been lower than foreign countries, don't look at the current Huayang Power's wages and benefits are very high, but if compared with foreign car factories, it seems that it is still a lot worse, after all, an exchange rate can be placed there.

"Well, Wuyun, you and Master Yang discuss it, don't do the all-aluminum body of this low-end model first, start with our Qoros model, and strive to open a breakthrough in high-end cars."

Wuyun quickly understood what Jin Xiaoqiang meant, indeed such a technology, of course, at the beginning, it was better to use it in high-end luxury cars, after all, people who can afford such a car are not bad for money!
