Mr. Lao's meaning is very clear: broadly speaking, the suspension system is a part of the chassis of the car, and is the most important component, any change to the suspension system will have a direct impact on the safety of the vehicle, and then affect the safety of the passengers on the car.

Chen Geng has only graduated for more than a month, and he can come up with a complete set of suspension system modification plans based on 212 Jeep? And it is not a small break on the basis of the original suspension, but a complete abandonment of the original set of suspension, with a set of suspension that has never been used in the country to replace it, isn't this a joke with the lives of passengers?

In a word, the old gentleman was angry and angry.

But Chen Geng felt very warm, this is the style of the older generation of educators, and after listening to the old gentleman's reprimand respectfully, Chen Geng explained: "Teacher, I always remember what you told us in class, and I never dare to joke with other people's lives...... I know you don't believe me when I say this set of suspension is fine, but that car is all the way from Jiangnan Province, and the chassis has been modified in the same way, you can check it in our school's car room, and also help the students check my homework. ”

Under normal circumstances, a professional in automobiles, if he is not fully sure, will never drive a car with a heavy suspension system with heavy safety hazards to run thousands of kilometers, Chen Geng dares to do this, it shows that he has full confidence in his modified suspension. The old gentleman naturally understood this truth, and when he heard this, he was stunned for a moment, and then his face eased a lot, and he glanced at the 212 jeep and said, "You came here in a car that you modified yourself?" ”

Although Chen Geng has graduated, since he has taught him, Mr. Song Jingying thinks that he has the responsibility to help Chen Geng do a good job, which is a bit ugly. If there was a problem with Chen Geng's modified car, it would be the signboard of the Department of Automotive Engineering of Huaqing University, and the old gentleman would never allow such a situation to happen, but Chen Gengneng took the initiative to let the Automobile Office of Huaqing University monitor his modification. The old gentleman was still very happy, and said immediately: "Okay, if there is really no problem with your modification, then I will help you recommend it to BAIC." ”

Why does the old gentleman dare to say this, because the old gentleman is not only the founder and dean of the Department of Automotive Engineering of Huaqing University. At the same time, he is also the leader of the automobile professional advisory group of the Capital People's Government, the chairman of the National Highway Society Bus Society and the honorary director of the China Highway and Transportation Society, and has a close relationship with the Capital People's Government and BAIC Group, and has a close relationship with the executives of BAIC Group.

But Chen Geng smiled bitterly: "Teacher, what I want to say to you is, if you are sure that there is no problem with my design, can you not talk to BAIC Group?" ”

"Don't talk to BAIC Group?" The old gentleman was stunned for a moment: "Why?" ”

Putting more advanced technology into production. In the old gentleman's opinion, this is a great thing for the benefit of the country and the people, but Chen Geng is not happy?

"To tell you the truth, this project is a major revenue item of our East China Military Region, and now that the state is reducing military spending and focusing on economic development, the financial pressure on the army is very great......

After listening to Chen Geng's reasoning, Mr. Song Jingying didn't know what to say.

From a personal point of view, he believes that if Chen Geng's design is not problematic, it is enough to prove this child's talent in automotive engineering, and if he can take this opportunity to enter the sight of the leaders of BAIC Group, it will not only be an excellent opportunity for his future development. It is also an opportunity for the automobile industry of the republic to grow up with good seedlings;

But he also knows that the army has indeed been very difficult in the past two years, and judging from the direction of the country, it will be for a long time to come. The state will inevitably persist in reform and opening up and persist in taking economic construction as the main direction, and the life of the army will not be easy for a long time to come; even the fact that I am in the capital have heard about the 212 jeep modification in Haizhou is enough to show that this modification business is booming, and not to mention anything else, at least it will help a lot to ease the pressure on the financial expenditure of the East China Military Region. From this point of view, it is indeed a good thing to help Chen Geng keep this secret. But......

Without waiting for the old gentleman to make up his mind, Chen Geng spoke again: "Teacher, I believe that the leading comrades of BAIC Group are not blind or foolish, if they really take a fancy to our modification technology, they can come to us through the East China Military Region to introduce it, and our East China Military Region can also take this opportunity to exchange some things with BAIC Group, so ......"

I have to say that Chen Geng's words really entered the heart of Mr. Song Jingying, and he also reacted: Chen Geng is right, the old 212 jeep has been modified, since he has heard it, there is no reason why BAIC Group can't hear it, now that they know, what should they do, do they still use their own teaching craftsman to put their beaks? They naturally know what they should do, and in this case, they don't have to do anything, and let things develop as they should.

Thinking of this, the old gentleman finally nodded: "Since this is the case, then I won't tell the comrades of BAIC Group first, but your car may have to be put here for a while......"

"It's okay!" Chen Geng said without hesitation: "Teacher, you can check how you want, just notify me when the inspection is over......"

Chen Geng so confidently handed over the car to himself for inspection, the old gentleman was a little moved, but he didn't say anything, but directly lay on the ground and began to check the 212 jeep that Chen Geng drove.

Chen Geng didn't feel surprised, and he didn't make a fuss, the old man is such a person, he is rigorous in his studies, nothing is unusual, but he is a little curious, what will the old man say about the suspension system he designed?

Although he also knew that Chen Geng had studied with the engineers of Wolfsburg in the magic capital for more than a year, he did not think that more than a year of study could make the level of an undergraduate student majoring in automotive engineering improve by leaps and bounds, but as he looked at the past little by little, his face began to become strict: although he did not count jù as support, but with his own experience, the old man thought that this was a set of design very scientific. The rigorous suspension system, all the designs are very mature, and it is completely impossible to see the work of a recent graduate of the automotive engineering department, and Song Jingying even feels that he is looking at the work of a master.

Of course, he is not wrong to say so, Chen Geng's egg pain is based on the 212 Jeep's front and rear integral axle structure to design this set of four-link non-independent suspension was already 2007, at that time Chen Geng was fully capable of serving as the chief designer of Wolfsburg, but Wolfsburg did not give him a stage to display his talents, and a guy who is qualified to become the chief designer of Wolfsburg naturally deserves the title of "master".

It's just that such a faintly master-style design appeared on a newly graduated undergraduate, it made people feel weird, and the old gentleman couldn't help but ask Chen Geng: "Chen Geng, is this suspension really designed by you?" ”

Knowing what the old gentleman meant, Chen Geng said without hesitation: "Teacher, I designed this set of suspensions. ”

He was rightly right, because he really designed the suspension himself.

Song Jingying's brows furrowed more and more, and he began to understand many places: first of all, he didn't think that an undergraduate student had such a demonic ability, but the 212 jeep, an old-fashioned jeep that uses the simplest leaf spring and hydraulic shock absorber as a suspension, is only produced in China in the world, and several off-road vehicles around the world, there is no off-road vehicle with an integral front and rear hard bridge is designed with this four-link suspension, which seems to be enough to show that Chen Geng did not copy it from somewhere;

It's just that, as Chen Geng's teacher, although he is more of a substitute teacher, but for the students he has taught, the old gentleman still has a kind of confidence, if Chen Geng showed such an outstanding talent when he was in school, he couldn't be unaware of it, so how to explain this qiē in front of him?

The old gentleman was a little confused.

"Tell me what are the advantages and disadvantages of your suspension?" After a deep sigh, Mr. Song Jingying was ready to take the school exam again.

"The advantages of this set of suspension are obvious, first of all, compared with the original leaf spring and hydraulic shock absorber barrel of the simple suspension, this set of four-link plus coil springs, hydraulic shock absorber suspension comfort has improved a lot, in fact, I designed this set of suspension The original intention is to improve the comfort of 212 Jeep, after cooperating with Poussin's passenger car tires and improved seats, the comfort of this car has indeed improved a lot, which is no less than our domestic Shanghai & Shanghai brand car;

As for the shortcomings, it is also obvious that compared to the original set of suspension, the cost of the improved suspension is higher, and the cross-country ability in some extreme cases is somewhat weaker than before. In addition, tires, coil springs and hydraulic shock absorbers are all accessories of Poussin, and the source of accessories is relatively limited. ”

After listening to Chen Geng, the old gentleman had already nodded again and again, he now somewhat believed that this set of suspension was really designed by Chen Geng, although he still couldn't understand why Chen Geng was able to make such a mature design, but the old gentleman who was happy to see the material was ready to continue to squeeze this kid who gave him a huge surprise......
