Chapter 290: Whether the suspension is good or not depends on tuning
readx;? After Li Fanyu left the venue, the first thing he did was to drive to the power company. Pen % fun % Pavilion www.biquge.info
Although the time 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 a golden nine, silver and ten diamond spring, and there is generally a sales fatigue period after the Spring Festival. However, Zhengxin's sales model is special, mainly relying on online sales. Therefore, compared with the traditional 4S store sales model, Zhengxin is not greatly affected by this.
The two production lines of the power company are still rotating in succession even after the year. The number of workers has almost doubled compared to when Power was first founded. Splitting into two shifts to rush work has become the norm for the company, and there is no such thing as an off-peak season.
Sales of the A4 have stabilized, firmly occupying the top three sales of B-segment cars. Although A6 has just come off the assembly line, whether it is normal sales or group buying of various company units, it is a hot hit. Even with the production capacity of the production line introduced in Guangqi, production is carried out non-stop every day, except for the four hours when some machines are cooled.
That's it, there is also a backlog of orders.
Today, Sun Guoyi is resting, and the deputy manager on duty in the factory is a deputy manager named Qian Hang. This person was also among the old employees of Zhengxin Power when it was first established, and Li Fanyu had contact with him a few times, but he was not very familiar with him.
Seeing Li Fanyu coming late at night, Qian Hang thought it was a spot check by the leader. Hurry up and gather around Li Fanyu to listen to the announcement.
Li Fanyu looked at him with a trembling look, and was a little funny: "What are you doing with me?"
"Inside... Mr. Li, what do you want to see, I will accompany you. ”
Li Fanyu waved his hand, "No, hey, wait a while... In this case, you can find eighteen road posts for me to set up in the square in front of the company, and I will be useful in a moment. After speaking, he stopped Qian Hang's footsteps and opened the mysterious workshop that was usually sealed in the depths of the company alone.
Although I don't understand the president's intentions, the orders of the boss must be carried out. Qian Hang called the security guard with the walkie-talkie, and after a while, the venue was arranged.
Qian Hang and a few security guards waited in the square for half an hour before they saw a beautiful sports car drive out of the company.
Li Fanyu of the chicken thief, of course, you have to try the performance of the mini first!
Ahem... Don't you fight an unprepared battle?
A group of people were so shaken by the bright headlights of the car that they couldn't open their eyes, and hurriedly blocked their eyes with their hands, Li Fanyu found out... It turned out that it was convenient for me to be a high beam dog.
He quickly adjusted the headlights, opened the door and got out of the car, and instructed the security guards to roughly set up the road posts.
This flat square was actually an abandoned foundation, and not long after the power company was taken over, Sun Guoyi proposed to buy the land together.
Because this area was originally a factory for the production of motorcycles, and later the industry was sluggish, and many factories under construction were also idle. The land is quite remote near the sea, and it is almost transferred at the price of cabbage.
Li Fan was as good as a stream, and only spent more than one million yuan to put it down for the 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. There was a big black empty field in front of the door, and it looked quite panicked at night. The company took into account that the workers often worked night shifts and needed to park, so they paid some money to install a few street lights and use them as temporary parking.
At this moment, it is used as a test site.
The sight at night was average, and Li Fanyu felt a little unsmooth after opening two laps. The trip was just to test the performance of the mini designed by the lab, so I only spared three laps back and forth.
However, after these three circles, Li Fanyu still has a little bottom in his heart.
Some of the interior design of the mini is different from the mini of the previous time and space, but the overall layout is basically the same.
The current mini doesn't seem to have suffered much in terms of handling.
After the test just now, Li Fanyu just felt that the suspension was a little soft. The roll is more severe when cornering, which affects some driving feelings.
Presumably, when Mr. Han designed the caterpillar suspension system, he also pursued the comfortable ride of the sedan.
If the suspension could be tuned to be tougher, it would be perfect!
Well... This job will be handed over to Wang Rui. That thing had been blowing the cowhide clanging before.
Thinking about this, Li Fanyu drove the car back to his own separate parking lot in the company, parked it, said hello to Qian Hang and returned home.
Early the next morning, Li Fanyu transported the mini produced by the power company using the super production line to the laboratory.
Wang Rui was quite excited when he was instructed to take the team to be responsible for the task of chassis and suspension tuning. He heard about the events at the press conference last night, and he was full of gratitude to Li Fanyu for handing over such an important matter to himself and letting him do it.
This product has been worried about the progress of research and development for the past two days...
Compared to R&D, tuning is still relatively easy, but it is only relative.
It is said that independent suspension is better than non-independent suspension in terms of performance, but this is only common sense.
A good tuning engineer is fully capable of tuning a non-independent suspension infinitely close to an independent suspension in terms of performance.
For example, these two suspension methods are like two martial arts minds. In terms of realms, 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, even if the "talent" is high, it depends on how many levels the mental method has been practiced.
The ten-layer garbage heart method is not so strong as the peerless heart method of the first layer.
Therefore, when we look at whether the suspension of a car is good or not, hardware is one thing, and later tuning is also an important factor.
Or, to some extent, the decisive factor.
As is the case at the moment, the mini has to work hard to adjust it in order to go to the test.
At present, the research and development of the mini is roughly ok, and all that is being done is some finishing tests. Han Lao did not leave after the completion of the suspension project, and was still half-visiting and half-guiding in the laboratory at this time, so Zhengxin's six teams were still very busy.
Wang Rui ignored Lao Zhang's beard and glare, handed over the work in his hand to others, and led his friends into the maintenance workshop and began to adjust.
Li Fanyu was also very interested in this work, and assigned the work in hand to Sister Wang and Huang Qi, and also came over to join in the fun. But when it comes to tuning, he's a pure layman. I can only look at the progress here anxiously, and then personally accept the test, and then put forward opinions for modification.
That's it, a total of twelve students, plus the help of people in the maintenance workshop pillars, the adjustment work was carried out for three consecutive days.
After a hot magic change, the tuning work is finally completed.
At this time, the suspension system on these two mini cars has been very different from the original version that Han Lao and several expert teams have worked hard for.
Under the condition that the main structure remains unchanged, the spring rate, shock absorber damping, caster angle of the kingpin, the camber angle, the offset distance, and the toe angle have all been changed by Wang Rui.
Because the changes were too big, Wang Rui and others who couldn't be restrained in the end... Even the subframe structure has been re-planned.
But not to mention, after running two laps in this final tuned version, Li Fanyu really felt a sense of ease.
How to say it...
The legendary unity of man and car, I'm afraid it's nothing more than that.
After pulling the car to a special test site and running for a few kilometers, and after confirming that there were no problems and hidden dangers, Li Fanyu notified reporters from various media by phone.
The pile-wrapping test can be carried out tomorrow!(To be continued.) )
