Chapter 1443 Sophistication of Materials
After listening to Liu Gong's words, Jiang Chen thought for a while and then nodded, "According to Liu Gong's words, the only options available to us are manual transmission, automatic transmission, and this dual-clutch transmission. The transmission can basically be eliminated, so there are only two types left. One is an automatic transmission, and the other is a dual-clutch transmission."

"That's right." Liu Gong nodded and said, "And this can also be applied to our two models. For the main high-end brand sports car, I recommend this dual-clutch transmission. As for the people-friendly version of the sports car, I recommend It is recommended automatic transmission. In this way, no matter in terms of price or driving experience, they can be distinguished, and they are more suitable for the targeted user groups.”

"So these two transmissions, do we have the technology in this area, can we manufacture them?" Zhou Gong asked.

In this regard, Liu Gong smiled and said: "We have no problems with automatic transmissions. We have actually started research in this area very early, except for the automatic transmissions that have been applied to our mid-range models. We have successfully developed continuously variable transmissions and seven-speed automatic transmissions. Therefore, there are no technical obstacles to the application of this aspect in sports cars. As for this dual-clutch transmission, to be honest, we have also studied it. But the effect is not It is not ideal, mainly because the internal structure is too complicated. Although this transmission appeared very early, it has been several decades. But the research and development and manufacturers of this transmission in the world are still A few. This is mainly due to the difficulty in the processing accuracy of parts, the use of materials, and the ordering of components."

In simple terms, everyone's faces turned frustrated, and Liu Gong then reversed and said, "However, it's not hopeless. This is mainly due to the fact that there are such things in the materials and some equipment we brought back from the Soviet Union." Research and related samples. These are currently sealed in the 313 warehouse and data storage center. If we start the relevant imitation research now, I believe that we should be able to keep up with the overall development progress of our project."

Hearing Liu Gong's words, Zhou Gong nodded and he laughed and scolded: "Old Liu, you are trying to scare us to death. If this is the case, then you should start quickly. This transmission is our high-end The key to technology in the sports car market."

"It's okay at the beginning, but there is no funds. We don't have any extra funds to distribute this newly opened project." Liu Gong stretched out his hands.

In this regard, Zhou Gong rolled his eyes and said: "Good old Liu, you have been waiting for me here for a long time. It is not easy to get funds, and Xiao Jiang is sitting here."

Hearing Zhou Gong's words, Jiang Chen shook his head helplessly and said, "No problem, later you come up with a plan and submit it for discussion, and we will speed up the process."

"Hehe, then I can thank Mr. Jiang." Liu Gong got what he wanted, and then said with a smile on his face.Regarding this, everyone rolled their eyes again and again, making fun of Liu Gong.

"Okay, what's next?" Jiang Chen asked.

Zhou Gong thought for a while and then replied: "It should be about materials. Materials also play a very important role in the overall performance of sports cars. In this regard, I am afraid that I will trouble Wu Gong in the materials laboratory."

Regarding this, Wu Gong shook his head with a smile and said: "I can say a few words about the material, but I don't understand the car. So, first, let's talk about the material of the sports car. What are the requirements, so that I can judge and see if our materials laboratory is competent."

"Yes, that's right, I forgot about it." Zhou Gong apologized immediately.After sorting out his thoughts, Zhou Gong then said: "Compared with ordinary cars, this sports car has higher requirements for materials. The materials used in it mainly have these characteristics. It is strong. Because the speed of the sports car is faster, the burden on the body is relatively large. This requires the strength of the entire body material to be strong enough to cope with this burden and pressure. Secondly, it is light in weight. Reduce the weight of the car Body weight is an important way to increase the speed of the car. Therefore, the current sports cars are all made of lighter materials, so as to greatly reduce the weight of the car body and increase the speed.

What's more, it has better toughness and higher resistance to oxidative fatigue.Because the vehicle speed is relatively high, the material on the vehicle body will be slightly deformed due to the pressure it receives, so there are certain requirements for the toughness of the material.And if things go on like this, the material will fatigue, so it must have a certain fatigue resistance (refer to metal fatigue).As for other aspects, it is similar to ordinary cars, but the requirements are higher, and even some parts can be said to be harsh. "

Zhou Gong took a look at Wu Gong and continued: "At present, the materials used in most sports cars in the world mainly include these types, including aluminum alloy, titanium alloy, new carbon fiber, and polymer engineering plastics. In addition, there are high-strength special steel, glass, car paint and other related materials. Therefore, this is a very large system project."

Wu Gong heard Zhou Gong's list, thought for a while, and then said to Zhou Gong: "We don't have any problems with the two materials of aluminum alloy and titanium alloy. We have been working on the aluminum alloy itself. Research, so the results in this area are relatively fruitful, enough to support your needs in this area. As for titanium alloys, this is mainly due to the information obtained from Su*, so we have made great progress in this area , There is no problem. In addition, we have accumulated a certain amount of polymer engineering plastics. However, we have mainly used this material in some weapons and equipment before, but I think there is no big problem in applying it to the car body. "

Hearing Wu Gong's words, everyone smiled.However, Wu Gong quickly poured cold water on them: "But in this new type of carbon fiber material, we have not been involved much. This is mainly because the research of this new type of carbon fiber material is difficult and consumes a lot of energy. It took a long time, and it is currently the most advanced cutting-edge technology in the world. In addition to our own research and domestic exchanges, our technology and data sources are also the part of the data we obtained from the Soviet Union. But in this In terms of new carbon fiber materials, their research is not much. So in this regard, we are still groping. Besides, the focus of our materials laboratory is still on metal materials. For this non-metal material Research is also limited."
