Chapter 28 Is he here to study?

Li Weidong picked up the tool and began to disassemble the gearbox of the crown car.

As soon as the so-called connoisseur reaches out his hand, he will know if there is any, especially mechanical repair. When repairing a car, you only need to look at the disassembly sequence of the car mechanic to know his proficiency in the mechanical structure of the car.

Li Weidong is naturally very skilled in dismantling the gearbox of the crown car. With Li Weidong's understanding of the seven-generation crown, even if the whole car is completely disassembled into parts, it can be put back again.

The Seventh Generation Crown was born in 1983. At that time, RB had not signed the Plaza Agreement. It was the most prosperous era of RB companies. In that era, the number of RB companies was very large, and the profits of the companies were also very good, so it also drove the automobile industry. sales.

The Crown is a luxurious B-class sedan, which is more suitable for business. It is the car driven by the boss when talking about business. In the era of good RB economy and high corporate profits, the Crown is the first choice of the bosses, and it has a relatively high retention in the RB society. quantity.

In his previous life, Li Weidong was a trainee at RB for three years, and he also repaired cars for three years. This kind of seven-generation crown, Li Weidong repaired a lot, so Li Weidong knows the structure of the seventh-generation crown very well.

Looking at Li Weidong's skilled disassembly of the gearbox, Liu Jinlong was 100% sure that Li Weidong had repaired this car, otherwise it would be impossible to have such a skilled operation.

This crown is an imported car. There are only two in the province. This Xiao Li is so familiar with the structure of this car. What is his origin? Liu Jinlong was even more surprised.

After a while, Li Weidong had removed the gearbox assembly, and at this time, all the masters in the workshop had gathered around, and no one had ever seen an automatic gearbox.

What part is this, why haven't I seen it?

This is the gearbox, from the imported crown car.

Gearbox? It can be made so small! This imported car is amazing!

I heard that this gearbox is different from our gearbox. This gearbox does not need to shift gears. It can run forward as long as you step on the accelerator.

Don't change gears, don't you even save the clutch? There is only one brake and one accelerator left under your feet.

Car mechanics, you talk about it one by one.

At this time, Li Weidong took up the attack and began to disassemble the gearbox assembly.

Wait a minute, don't dismantle it directly! Liu Jinlong was taken aback. In his opinion, such a small gearbox must be a very precise part. He was afraid that it would be damaged by Li Weidong.

Don't worry, I have dismantled a lot of this thing. Li Weidong started immediately after speaking.

Liu Jinlong's heart instantly raised his throat, for fear that the gearbox would be damaged at all. Li Weidong is very skilled and disassembles the gearbox.

I found the problem, the belt is damaged, and it needs to be replaced. Also, don't forget to bring a transmission oil, it has to be imported, and it has to be replaced later. Li Weidong directly gave the transmission belt to the pulled out.

Liu Jinlong asked cautiously, After changing the belt, can you put it back on?

Definitely can, can it be disassembled or not installed! Li Weidong said with a smile.

You have to put all these back, and then go. Liu Jinlong added: When you took it apart just now, you moved too fast, I didn't see it clearly, if you left, I guess I won't be able to put it back. already.

I'll fix the car before leaving, so the head office will do it! Li Weidong paused, then said, But you have to take care of the meal. I don't have a meal ticket from your factory.

At this time, the driver of the crown car interjected and said, This little master, as long as you fix this car, I will invite you to dinner.

Li Weidong looked at the driver of the Crown Car, then stood up, walked over to him, and said, Master driver, when you drive, do you often run in neutral?

The driver nodded proudly: I drive,

That is absolutely fuel efficient.

Li Weidong took a long sigh and then said: If you drive this car in the future, don't run in neutral, otherwise the gearbox will be broken.

The driver of the Crown Car was taken aback for a moment, apparently not understanding what Li Weidong meant.

Li Weidong explained: This crown uses an automatic transmission, which is different from our manual transmission structure. When people move forward, they are in D gear, when going uphill, they are in S gear, and when they are reversed, they are in R gear, and when they are parked, they are in N gear. , Parking should be in P gear. These can't be mistaken. Don't push it to N gear when running, otherwise the gearbox will be damaged.

Ah? I thought that the N gear was the neutral gear! The driver of the crown car looked a little flustered.

N gear is neutral, but it can't be used like a manual gear. Li Weidong explained.

Cars with carburetors have a very special operation, that is, after the car starts running, put it in neutral and let the car slip for a certain distance, so that driving is more fuel-efficient.

Cars with carburetors do not supply fuel to the engine when they are in neutral.

Therefore, many old drivers drive cars with carburetors, but they do not give oil and do not put in gear. When the car starts to run, and the accelerator needs to be applied, just hang up the gear, step down on the accelerator, and when the speed of the car increases, pick it up and run in neutral for a while. This will save more fuel.

Later, the car engines became EFI, and as long as the car was running, the oil was used, and this operation lost its meaning.

However, for a car with automatic transmission, it is obviously very harmful to the gearbox, and the gearbox is easily damaged because of it.

The driver of the crown car doesn't understand this. He still uses the previous fuel-saving method to drive. After a kick of the accelerator, he will switch to N gear, and then switch to D gear when he needs to refuel. There will definitely be a problem with the gearbox. The first damaged It's that drive belt.

Knowing that it was his improper operation that caused the vehicle to malfunction, the Crown driver immediately panicked, for fear that he would be punished by the leader.

Li Weidong obviously saw the driver's careful thinking, and he immediately opened his mouth to comfort him: Master driver, just pay attention to driving in the future, let's not take it as an example. As for the reason for the failure of this car, I will not tell others.

Seeing that Li Weidong was willing to keep the secret for himself, the driver of the crown car held Li Weidong's hand gratefully, and then said sincerely, Little comrade, thank you, I really invite you to dinner at noon today!

...

In the repair workshop of the Yellow River Plant, all kinds of parts are still very complete. After about an hour, Liu Jinlong found a replaceable drive belt.

Li Weidong was about to put the belt back into the gearbox, but Liu Jinlong said, Little Li, can you move slower this time, and let us see how these parts are put back together.

Brother Liu, you really like to learn. Li Weidong smiled, and then said, How about I tell you about the structure of this automatic transmission first?

That's great, I'm just curious, why this gearbox can run all the time without shifting gears, just stepping on the accelerator. Liu Jinlong said and leaned up, then took out a cigarette and handed it to Li Weidong, which was counted as tuition.

Li Weidong glanced at it, but luckily it wasn't the one he gave to Liu Jinlong.

Li Weidong began to introduce: Actually, there are two types of automatic transmissions, one is hydraulic automatic transmission, the other is CVT, this Crown uses CVT, you see, there are two in this transmission. Is the shifting disc? This is the principle of continuously variable shifting...

While talking, Li Weidong simply explained other parts of the crown car.

Soon, Li Weidong was surrounded by a large group of people, all of whom were masters in the repair shop, listening to Li Weidong's explanation of the mechanical structure of the Crown sedan.

In fact, the parts in the car are all the same. There are also experienced car mechanics here, who are very familiar with car parts. But putting those familiar auto parts into an imported car, the car repairers are a little confused.

RB people are more detail-oriented, which is also reflected in the RB car. The Crown is a business B-class sedan, and it reflects the details of the RB car everywhere. Other countries really can't do this.

For these car mechanic, this crown car is high-end and fresh. It is rare for them to have access to a world-class business car. What Li Weidong explained is exactly the knowledge they are eager to get. .

As a result, more and more people gathered around, and people kept asking questions during the period. And Li Weidong can answer them one by one. After all, his theory of auto repair and his understanding of Crown sedan are much higher than those of these car mechanics.

...

Workshop Director Wei Bin walked out of his office and saw a group of people gathered around.

What happened? Wei Bin walked over and saw Li Weidong explaining the structure of the crown car to everyone.

Who is this person, not from our workshop. It looks familiar... By the way, I remembered that there was a company from Qinghe today who said he was coming to visit and study, isn't that the guy! I even let him look at it casually. Look.

Wei Bin turned his head and was about to leave, but the next second he suddenly stopped.

Huh? Something's wrong, he's here to study? But looking at this posture, he seems to be teaching our people! How do you feel that he's here to guide the work!
