Era: Retired from the army at the beginning and returned home

(This chapter is actually planned to be deleted. According to the chronology, it is a bit watery. If it were put on the shelves, it would definitely be reduced, but it does not affect viewing, so you can watch it quickly. I will update one more chapter today to make up for the water. Bar)

At the bus station, what driver Zhao Dajin reported at noon today attracted the attention of the bus station director, because if what Zhao Dajin said was true, then the accident that occurred this morning was not necessarily sudden. But many cars have such safety hazards.

So the station manager immediately called the repair shop. After many drivers knew about this, the bus station almost stopped operating this afternoon. Not knowing there was a safety hazard, the car continued to drive out, it was nothing. But knowing that there was a safety hazard, he continued to drive the car with passengers on board. If an accident occurred, he, the station manager, could not bear the responsibility.

After Director Zhang took people to the station, he almost cursed after understanding the situation. Who said it was normal for the steering wheel to be tight, and it was said by someone from their repair shop.

However, the repair shop cannot be entirely blamed for such a thing. Cars at the station come to the repair shop for maintenance twice a year. However, after the car arrives at the repair shop, it is basically a simple inspection. It does not take more than two hours from the time the car enters the factory to the time it leaves the factory. Basically, as soon as the car comes in, it is urged to be inspected. , don’t delay operations.

In the absence of instruments and testing equipment, check the surface for an hour or two at most. The driver said that the steering wheel was a little tight. When no obvious problems were found, he would think that he had been driving the car for a long time, the brakes were a little loose, and the horsepower was a little insufficient.

Paying attention to it is indeed not paying attention to it, but after the car has been in the factory for a short period of time, as long as the car can drive and run, the repair shop can check and find out any problems.

Director Zhang drove to the scene of the accident to check. The teeth of the steering bearing were broken, causing the steering wheel to malfunction.

Then I came back and dismantled Zhao Dajin's shuttle bus, and found that the bearing fit was too tight and was stuck. Not to mention the steering wheel turned the entire car. Even if the car was suspended in the air, it would be difficult to steer in place. This is equivalent to the strong friction of the latching teeth every day. The final result is that either the latching teeth are broken by grinding or the bearing is broken. However, the bearing is so thick, it is the latching teeth that are most likely to break.

The cause of the over-tightening of the bearing was also found. The transmission shaft was twisted and deformed, and the straight line distance was the longest. This deformation was basically a bend. With this bend, there was a little gap in the teeth, so it was directly stuck.

So Director Zhang asked the station to send people here to bring all the employees in the factory who could work temporarily. It won't work if we don't work overtime to repair it. If the car is not repaired, the station will be out of service tomorrow.

It's just that the problem is found, but it's not easy to solve. I originally planned to disassemble the bearing and forcefully knock it flat, but the bearing on the car is not thin, and it cannot be knocked flat by human power. You need to find a lathe to flatten it. Then I contacted a lathe factory that has stamping capabilities. Over there at the bus station, cars are being unloaded one by one.

Even so, this method still only treats the symptoms but not the root cause. If there are so many bearing deformations now, it must be because the bearings are not hard enough. Even if they are flattened, this situation will still occur in the future.

But replacing new bearings is not easy. You can only do it step by step. If the car has such a problem in the future, just repair it in time and there will be no major problems.

"The driver at your station reported the situation in a timely manner. If you don't explain the situation, the accident this morning will be treated as an accident. It is really possible that such a thing will happen again, or even be more serious. Then you will not be able to sit still in your position. .”

"Where is it? After all, it's all thanks to the little master in your factory who told him about this problem, otherwise he wouldn't have thought of it."

"Who is the little master in our factory? Do you know his name? What did he say to your driver?"

Director Zhang was chatting with the bus station manager in the station manager's office. Regarding repairing the car, after finding the problem, the repairman below knew what to do. It’s just the words of the webmaster that made Director Zhang strange. If someone in his factory had known about this situation, why didn’t he report it to him? Even if the guess was wrong, it would be better to waste some time to check it thoroughly than to come back after the accident. Find a reason and be strong.

"I don't remember this clearly, but our driver hasn't gotten off work yet, so I asked him to come over and ask."

Director Zhang nodded and asked the station manager to call the driver. And when Zhao Dajin showed up, it goes without saying that Director Zhang knew who he was. Because a few days ago, when he sent Luo Cheng to work, he took the master's car. The possible reason for telling the driver that the steering wheel was tight was probably what Luo Cheng told him.

But even if he guessed it was Luo Cheng, Director Zhang still asked Zhao Dajin carefully. After confirming that it was Luo Cheng who told him, he then asked what Luo Cheng mainly said to him.

From Zhao Dajin's mouth, several possible reasons for Luo Cheng's guess were directly stated. One of them was completely consistent with the current situation. This kind of theoretical knowledge was completely unavailable to repairmen like them. But the domestic automobile industry has just started. Unless they go abroad, where can repairmen learn this knowledge?

What's more, if many repairmen are masters and apprentices, there are even people with little education. If you put the book in front of him, he might not be able to read it.

Factory Director Zhang plans to see Luo Cheng tomorrow to see if he can solve this problem.

Luo Cheng made dinner in the cafeteria and ate in the security room, where people mainly chatted.

"System, sign in."

"Congratulations to the host, I got a rubber stick and a tear gas injector (a bottle)."

Wait a minute, didn't I sign in at the auto repair shop? How did I get this thing? Luo Cheng suddenly came to his senses. This security department belongs to the Security Department. The system is so sloppy. Even so, why are there only two things? There were several of the same before.

Rubber baton, this thing is useless these days, an electric baton will do. This thing is designed to not be so bloody. It is relatively smooth and the hardness is okay. But when you encounter a ruthless person, holding an iron pipe in your hand is more of a deterrent.

Tear gas sprayers are also pepper sprays, which are used by women for self-defense. Luo Cheng is a grown man~~ Thinking of the scene of rural women walking as fast as they can carry hundreds of kilograms of rice, it seems that Luo Cheng needs it more than rubber sticks.

"If I had known this, I might as well have signed in at the bus station in the morning. Maybe I could get some tea eggs, braised chicken legs and so on."

While Luo Cheng was chatting with the people in the security room, he was distracted thinking about signing in. But there was nothing too disappointing, because even in the repair shop workshop, Luo Cheng felt that the system was stingy and would not provide him with the equipment to repair cars in the future. You can usually see the items you get when you sign in. If you give him a wrench, screwdriver, etc., they may not be as good as what you get now.
