Automotive Black Technology Chapter 178: : Low-level mistake

www.lnmao.org, the fastest update to the latest chapter of automotive black technology!

Car companies that were already eyeing Zhengxin Audi immediately seized on this topic and made the matter a hot topic on the Internet.

“The gearbox was shaking abnormally, and a fatal flaw was discovered when the first batch of Audi A4 rolled off the production line!”

"National sentiment cannot represent the strength of a car company. Audi A4 - a hasty project, a patchwork product."

“Quality control requires time and design requires technical accumulation. Zhengxin Audi still needs to learn from established foreign car companies.”

"The myth of developing a model in two months has finally been shattered. Trust me Audi, what do you want me to love you with?"

Chinese people are all about getting off to a good start, but when Zhengxin entered the B-class car market, it encountered an out-and-out bad start.

For a time, there were all kinds of bad reviews, and the reputation of Audi A4 dropped sharply.

Looking at this scene, Wen Xin, the boss of Longsheng Company, was very worried. If we don't find out the cause of the problem, the business will be put on hold.

As a result, Huang Qi's phone calls were almost all filled with calls.

Huang Qi's mouth was full of tears, but his car had a problem, so he could only swallow the complaints and anger of his partners. I can only reassure them again and again, saying that the company is doing its best to find defects and solve problems.

After Li Fanyu learned about it, he immediately stopped the production line and immediately recalled all the first batch of A4s delivered.

Obviously, this matter is a design flaw, otherwise not all cars would have the problem of abnormal shifting jitter.

A few cars are special cases, and they are all like this, which explains the problem very much.

But while he was annoyed, he was also puzzled; the A4 had been tested repeatedly before it was rolled off the assembly line, and logically the current situation should not have happened. Although the appearance of the A4 has been slightly changed, the internal structure is designed strictly in accordance with the drawings exchanged in Xapp.

Could it be that... something went wrong?

Seeing his frown, An Ning grabbed his hand and comforted him: "Stop thinking blindly. Everything has to be seen in the car. Only after it is disassembled can we know what went wrong."

Li Fanyu smiled reluctantly and patted the back of An Ning's delicate hand, saying not to worry.

But his brows still showed no sign of relief—encountering such a problem at the launch of sales was a huge blow to the Audi brand!

Under Li Fanyu's repeated urging, all the cars that first discovered the problem were shipped back to Zhengxin.

As soon as the car arrived, he couldn't wait for the laboratory to dismantle the car, so he directly checked all the cars with the diagnostic expertise.

At this glance, I immediately discovered the problem.

Under the display of the virtual structure specialized in diagnosis, the transmission bearing ring gears in the transmissions of these cars all showed spots of red, without exception!

In virtual composition, red represents damage.

You know, this is a new car! Damage to parts in a short period of time is due to two reasons; either there is a problem with the design of the car, or the quality of the parts is not up to standard!

Li Fanyu was so angry that he immediately summoned the people in the laboratory and maintenance workshop and gave an order: "Tear it down for me! Remove the transmission bearing ring gear and inspect them one by one to see what's fishy inside. ! ”

Zhu Zi led a group of workers to quickly dismantle the gearboxes of more than a dozen vehicles.

The moment the ring gear was removed, the R&D team present was stunned.

I saw that all the ring gears had been ground and dented! With apprehension, they immediately returned to the laboratory and tested the ring gear. As a result, as soon as the first step of dimensional measurement was carried out, the crux of the problem was discovered.

There is no problem with the material of the ring gear. The reason for the wear is because the diameter of the ring gear is three millimeters larger than the design drawing!

Li Fanyu is really angry. This is the lowest level mistake! Three millimeters! For a precision machine like a car, these three millimeters are enough to be fatal.

He immediately called Wang Meimei and asked her to call the heads of the quality inspection and purchasing departments over.

The new purchasing department manager is Wang Han, an old man who has been in charge of purchasing when Zhengxin was first established. After Zhang Su was fired, he took over.

With such a big thing happening in the company, he and Liu Chi, the manager of the quality inspection department, were so busy that they were checking and inspecting all aspects.

Now that Li Fanyu was called in, he immediately realized that the problem might occur in the link he was responsible for.

Ten minutes later, the two of them ran to Li Fanyu, sweating profusely.

"Mr. Li! Did you call us?"

Li Fan put the test report into his arms with a cold face, "See for yourself! Why hasn't such a serious problem been discovered! What on earth is going on?!"

The two looked at each other and picked up the test report issued by the laboratory. At this sight, they frowned almost at the same time.

"Mr. Li! This is wrong!"

Li Fanyu said coldly: "What's wrong?"

"In our purchase agreement, the transmission shaft ring gear is of this size. How can it be inconsistent with the design size?"

"Yes, Mr. Li, we have also gone through repeated inspections during quality inspection and acceptance. It is impossible for such low-level mistakes to occur."

Li Fanyu slammed the ring gear in his hand to the ground, "Then tell me, where is the problem?!"

The two of them saw that Li Fanyu was really angry and immediately fell silent, but their faces were full of grievances.

I really don’t blame them for this matter.

After the laboratory determines the part design, it transmits the dimensional parameters to the purchasing department. The purchasing department will then go to the supplier with the design drawings. After the suppliers make the designs according to the drawings, they will supply the goods to Zhengxin. After the final quality inspection, they can enter the production line.

This set of procedures should indeed not cause such errors.

Seeing that Li Fanyu's emotions were out of control, An Ning stepped forward and took his arm.

"Don't be angry first, let me handle it."

As soon as Li Fanyu wanted to speak, An Ning smiled and nodded, signaling him to control his anger. He breathed out, knowing that he was filled with anger and lacked reason. He waved his hands and turned his body to the side.

An Ning thought for a while and said softly to the two managers: "Mr. Li is also worried. I hope you can understand."

The two of them waved their hands quickly: "Director An, we completely understand. To be honest, we are also anxious when such a thing happens! We all watched Zhengxin come over little by little, and the company just followed us. Just like at home... If the problem really lies with us, we will have no choice but to do so. But the problem is, the ring gear purchase agreement does have this size! ”

An Ning frowned, thought about it, and said, "Let's go get the purchase agreement. Then ask the supplier to see when the agreement was signed and who handled it."

The two nodded and immediately returned to the office to check the matter according to An Ning's instructions.

Half an hour later, Wang Han ran back again sweating profusely.

He was holding an agreement in his hand, and his name was clearly written on the confirmation column.

But the person who handled this agreement was Zhang Su.

In other words, this is the last supply agreement handled by Zhang Su when the purchasing department was handed over. (To be continued.)
