Niu Xiaoqiang smiled noncommittally and looked at Chen Hong, who was silent. Chen Hong is the most authoritative, his opinion is relatively important, Niu Xiaoqiang smelled: "Director Chen, you are an old qualification in the automotive industry, I want to hear your personal opinions, and please speak freely, don't have any worries." ”

Chen Hong used to work in a tractor factory, don't think that the tractor factory only produces tractors, in addition to tractors, they also produce agricultural vehicles.

Agricultural vehicles belong to the category of light trucks, and the carrying capacity is generally only a few tons. Now Niu Xiaoqiang wants to produce heavy trucks, from a technical point of view, the chassis of agricultural vehicles and the chassis of heavy trucks are not the same, and the gap is still very large.

Chen Hong's expression was a little dignified, and he was not polite, and directly put forward his own opinion: "I have built a lot of agricultural vehicles before, and the technical nature of agricultural vehicles is already very complicated, if it is a heavy truck with a load capacity of dozens of tons, to be honest, I am very bottomless in my heart, Secretary Niu, there is one thing I am very curious about, you have not studied the chassis before, I don't know where your confidence comes from?"

This is equivalent to questioning Niu Xiaoqiang in person. Niu Xiaoqiang knew that Chen Hong was a straight person, and he was not angry, so he took out the key and opened the drawer with a smile, took out a document from it and handed it to Chen Hong: "Director Chen, you have some experience in automobile chassis, come and help me take a look first to see if my preliminary design plan is reasonable." ”

Chen Hong and Chen Fanghua were all shocked, they didn't expect Niu Xiaoqiang to have already come up with a preliminary design plan, it seems that Niu Xiaoqiang is not unprepared.

After a pause, Chen Hong opened the folder and lowered his head to take a closer look. Although Chen Fanghua didn't understand chassis technology, he could understand the drawings, and he also came over to watch.

Niu Xiaoqiang's drawings are very detailed, refined, and each line is marked with design parameters, as long as it is a person who understands machining, such as Chen Fanghua, you can understand it at a glance.

But what they can understand is the specifications, as for the good or bad of the design scheme, they can't understand it.

Chen Fanghua was concerned about the processing difficulty of the design structure, and he nodded while looking at it: "The processing difficulty is relatively low, as long as the original blanks are cast, I can process them all in two days at most." ”

Chen Hong didn't speak, and a look of surprise appeared on his face. After looking at it for a while, he raised his head and looked at Niu Xiaoqiang: "Secretary Niu, haven't you really studied the car chassis before?"

Niu Xiaoqiang shook his head with a smile: "Of course not, I have been busy during this time, I have read a lot of books on automobiles, and I have carefully pondered the transport truck in the factory that is about to be scrapped, and I have an understanding of the frame and structure of the chassis." ”

Chen Hong's eyes widened: "This is the research you have done?"

"Well, that's all I have. ”

Chen Hong stared at Niu Xiaoqiang like a monster: "Then, how did you draw this drawing?"

Chen Fanghua couldn't help but interject: "Director Chen, is this design drawing excellent?"

Chen Hong shook his head slightly: "It can't be said to be excellent, but it's not bad, but there are a few places where the structure is not very reasonable, but even so, this is not something that beginners can figure out." ”

Niu Xiaoqiang showed a curious look: "Director Chen, I don't know which places have unreasonable structures?"

Chen Hong turned the second page, pointed to the drawings and said: " This is the chassis height of the truck schematic diagram, if according to this height production, will cause the body in the driving process is not very stable, especially when turning, it is easy to overturn, in addition to here, this is the chassis rear axle structure diagram, in professional terms, this is called the rear axle hard axle suspension, although the structure you design can ensure the reliable load capacity of the vehicle, but ignore the strength of the material, as far as I know, we do not have this kind of high-strength pressure structure material in China, unless we go abroad to procure, otherwise we can not manufacture。 ”

Niu Xiaoqiang first answered the first question: " Director Chen, the first problem actually does not exist at all, I have done a detailed calculation of mechanics, in the case of such a high chassis, the truck only reaches a speed of more than 90 kilometers per hour, and turns less than 100 degrees of bends will roll over, you don't ignore the use of our trucks, they will be used in the mine in the future, under normal circumstances, truck drivers are impossible to operate like this, in the harsh working environment of the mine, truck drivers are even more unlikely to carry out this kind of operation. ”

"You can't ignore the size of the body, I designed a longer body length and a wider wheelbase than the average truck, as the saying goes, the bigger the ship, the more stable the chassis, so I wasn't too worried about the first question. ”

Niu Xiaoqiang smiled when he said this: "As for the material problem, it will be solved by Deputy Director Zhou, so we don't have to worry about it." ”

When Chen Hong heard what Niu Xiaoqiang said, he did not show convincing, but retorted: "Secretary Niu, you just said that you just read some books and observed the chassis of the truck, and did not conduct any actual tests, right? In this case, how can you ensure that the data you calculated is correct?"

Chen Hong originally wanted to say, "Aren't you talking on paper", but considering that it is impolite to speak like this, he changed the way he expressed it.

Niu Xiaoqiang understood what Chen Hong meant, and in order to let Chen Hong have a bottom, he took out the key and opened the door of the safe. This safe was moved by Niu Xiaoqiang from the Finance Department, and the safe is not big, and it can only store some important documents, and it can't save much money.

After opening the cabinet door, Niu Xiaoqiang took out something with a black shell from inside.

It looked like a thickened black brick, and the three of them had never seen anything like it before, and they were all confused, not knowing what it was.

Fortunately, Niu Xiaoqiang didn't let them wait too long, and quickly gave an answer: "This thing is called a computer, which is generally called a microcomputer in China, which means a microcomputer, and all the data on my design diagram is calculated through it." ”

Chen Fanghua and Zhou Kai don't know much about computers, but Chen Hong does.

He had previously visited and studied in a large state-owned enterprise, which had purchased several foreign CNC machine tools, and Chen Hong was shocked at that time, especially the automatic control equipment on the CNC machine tools, which made him feel extremely surprised.
