After Li Fanyu left the venue, the first thing he did was drive to the power company.
Although it is almost ten o'clock in the evening, the various workshops in the company are still brightly lit, and more than a dozen feeding forklifts are shuttling back and forth in the factory room.
It is said that the automobile sales market is like a golden, nine silver and ten diamond spring. After the Spring Festival, there is usually a period of sales fatigue. However, Zhengxin’s sales model is unique and mainly relies on online sales. Therefore, compared with the traditional 4S store sales model, Zhengxin is not greatly affected by this.
Even after the new year, the two production lines of Dynamic Company are still running continuously. Compared with when Dynamic Company was first established, the number of workers has almost doubled. Working in two shifts to rush work has become the norm for the company, and there is no such thing as off-season or peak season.
The sales of the A4 have been stable, firmly occupying the top three sales positions of B-class cars. Although the A6 has just rolled off the production line, it is still a hot seller, whether it is normal sales or group purchases by various companies. Even with the production capacity of the production line imported from Guangqi, production is carried out non-stop except for four hours every day to allow some machines to cool down.
That's it, there is still a backlog of orders.
Sun Guoyi is off today. The person on duty in the factory is a deputy manager named Qian Hang. This person was also one of the old employees when Zhengxin Dynamics was first established. Li Fanyu had been in contact with him several times, but was not very familiar with him.
Seeing Li Fanyu arrive late at night, Qian Hang thought it was a random inspection by the leadership. He quickly gathered his energy and gathered around Li Fanyu to listen to the announcement.
Li Fanyu looked at him with a trembling look, a little funny: "Why are you hanging around me?"
"Mr. Li, what do you want to see? I'll accompany you."
Li Fanyu waved his hand, "No, wait a minute... Now, you go find eighteen road posts and place them for me in the square in front of the company. I'll be useful for a while." After saying that, he stopped. Following Qian Hang's footsteps, he alone opened the mysterious workshop deep inside the company that was usually sealed.
Although I don’t understand the president’s intentions, my immediate superior’s orders must be fulfilled. Qian Hang called the security guard with his walkie-talkie, and within a short time, the venue was set up.
Qian Hang and several security guards waited in the square for half an hour before they saw a beautiful sports car drive out of the company.
Li Fanyu, a chicken thief, of course wants to try the performance of the mini first!
Ahem...don't fight an unprepared battle?
A group of people were blinded by the shining headlights of the car, and they quickly covered their eyes with their hands. Only then did Li Fanyu realize... It turned out that he had just turned into a high-beam dog for convenience.
He quickly adjusted the car lights, opened the door and got out of the car, and directed the security guards to roughly arrange the road piles.
This flat square was actually an abandoned foundation. Soon after Panxia Power Company, Sun Guoyi proposed to buy the land together.
Because this area was originally a factory that produced motorcycles. Later, the industry slumped, and many factories under construction became idle. The land is quite remote near the seaside and is sold for almost cabbage price.
Li Fanyu followed his good deeds and only spent more than one million to buy it for future expansion of the power company.
However, the area of the power company itself is not small, so it is not used for the time being. The large dark empty space in front of the door seemed quite scary at night. Considering that workers often work night shifts and need parking, the company spent some money to install a few street lights and use them as temporary parking.
At this moment, it happens to be used as a test track.
The sight was normal at night, and Li Fanyu felt a little uncomfortable after driving twice. This trip was just to test the performance of the mini designed by the laboratory, so I only went back and forth three times before giving up.
However, after these three rounds, Li Fanyu still felt a little confident.
Some of the interior designs of the MINI are slightly different from those of the previous MINI, but the overall layout is still basically the same.
The control feeling of the current Mini does not seem to be affected much.
After the test just now, Li Fanyu just felt that the suspension was a little soft. The car rolls more seriously when turning, which affects some of the driving experience.
Presumably when Mr. Han designed the caterpillar suspension system, he was also pursuing a more comfortable ride like a car.
If the suspension could be adjusted to be firmer, it would be perfect!
Well... leave this job to Wang Rui. That guy had made the cowhide jingle before.
After thinking about this, Li Fanyu drove the car back to his separate parking lot in the company, parked it, greeted Qian Hang and returned home.
Early the next morning, Li Fanyu transported the mini model produced by the power company using the super production line to the laboratory.
Wang Rui was very excited when he received the instruction to lead his team to be responsible for chassis and suspension adjustment. He heard what happened at the press conference last night. He was very grateful to Li Fanyu for entrusting him with such an important matter and letting him do it.
This guy has been feeling anxious for the past two days because he spilled the beans about the research and development progress...
Compared with R&D, adjustment is relatively easy, but it is only relative.
It is said that independent suspension is better than non-independent suspension in performance, but this is only based on common sense.
An excellent tuning engineer is fully capable of adjusting the performance of a non-independent suspension to be infinitely close to that of an independent suspension.
For example, these two suspension methods are like two martial arts books. In terms of realm, independent suspension is higher at the starting point than non-independent suspension, and farther at the end point.
However, most of the mental methods are divided into realms. No matter how high the "talent" is, it depends on how many levels of mental methods have been practiced.
The tenth-level **** mental method is no better than the peerless mental method at the first level.
So when we look at whether a car’s suspension is good or not, hardware is one aspect, and later adjustments are also an important factor.
Or to a certain extent, it is the decisive factor.
Like the current situation, if Mini wants to take part in the test, it must work **** the adjustment.
Currently, the research and development of the mini is generally OK, and some final testing work is ongoing. Mr. Han did not leave after the suspension project was completed. He was still in the laboratory half-visiting and half-guiding, so the six teams of Zhengxin were still busy.
Wang Rui ignored Lao Zhang's glare and handed over the work in his hands to others, then led his friends into the maintenance workshop and started to adjust.
Li Fanyu was also very interested in this job. He assigned the work at hand to Sister Wang and Huang Qi, and came to join in the fun. But when it comes to adjustment, he is a complete layman. . I can only watch anxiously as there is progress here, then personally check and test it, and then put forward suggestions for modification.
That's it, with a total of twelve students, plus the help of Zhu Zhu and others in the maintenance workshop, the adjustment work was carried out for three consecutive days without any fuss.
After a heated period of magic modification, the adjustment work was finally completed.
At this time, the suspension systems installed on these two mini-cars are very different from the original versions that Mr. Han and several expert teams worked hard on.
While the main structure remains unchanged, the details of spring stiffness, shock absorber damping, kingpin inclination, caster angle, offset and toe angle were all changed by Wang Rui.
Because the changes were too big, Wang Rui and others couldn't bear it anymore... even the subframe structure was redesigned.
But not to mention, after driving this final adjusted version for two laps, Li Fanyu really felt a sense of ease.
How to say...
The legendary integration of man and car is probably nothing more than this.
After pulling the car to a special testing site and running it for several kilometers, and confirming that there were no problems or hidden dangers, Li Fanyu notified reporters from various media on the phone.
The pile-circling test can be carried out tomorrow! (To be continued.)
