The main function of the clutch is to transmit and cut off the torque from the engine, since the clutch can be started normally when the clutch is just stepped on, it means that the clutch is effective in cutting off the power.

Then next, it is necessary to see whether the role of the clutch in transmitting power and ensuring smooth gear shifting is also very good.

Xu Guanglu slowly released the clutch, and at the same time hung into first gear, and the car slowly moved around.

The car started smoothly and without shocks!

Xu Guanglu, who was sitting inside, quickly came to such a conclusion.

This time, Xu Guanglu's heart was even more relaxed, and he began to run freely around the playground, and the gear was changed from the original first gear to the second gear, third gear, and even the highest fourth gear!

No matter from which aspect of the evaluation, the new design of the clutch is absolutely in line with the requirements of use, the combination is very smooth, soft, and when separated, it can also be done quickly, thoroughly, more importantly, compared with the previous double-plate clutch, by Zhou Jingming after the design of the changed single-plate clutch, the noise during work is also significantly smaller, and the operation is more light, and the driving intensity is greatly reduced!

These are all unexpected surprises!

In this way, Zhou Jingming not only solves the problem of breakdown caused by the burning of friction plates, but also improves the quality of Shencheng brand cars from the performance!

After going around a few times, Xu Guanglu stopped the car and walked out of the car.

"Director, how is it, does the performance of the clutch meet the requirements?" Zhao Ke hurriedly asked. But in fact, it can be seen from the expression on Xu Guanglu's face that the effect of the test drive is great!

"Very good! The car is easier to drive than the previous use of the double-plate clutch, Xiao Zhou, you have really made a great contribution this time!" Xu Guanglu couldn't hide the joy in his heart, and his eyes at Zhou Jingming became more appreciative.

"This time the test drive is just to verify the performance of the clutch, as for whether the problem of friction plate burnout can be completely solved, we still need to continue to carry out road running experiments to verify. ”

Zhou Jingming was not surprised by the current situation, in fact, such a result had long been expected by him, if the clutch he designed could not even achieve the most basic function, then he would not think about entering the mulberry car introduction project team.

What's more, it took so much effort to change the structure of the clutch, and finally it was to solve the problem of friction plate burning, although it has been proved theoretically feasible, but it has not been proved experimentally, and Zhou Jingming does not dare to pack the ticket.

"Yes, what Xiao Zhou said makes sense. The Long March is only half of the way, and there is still half of the way left. Xiao Zhao, tomorrow will start arranging workers to take turns to run away experiments 24 hours a day. After Zhou Jingming said this, Xu Guanglu also realized that he was happy a little early.

It is getting closer and closer to July 1st, there is not much time left for Xu Guanglu, and then the process of road running experiments must be accelerated, although the 24-hour uninterrupted sports car does not meet the rules of automobile testing, but Zhou Jingming also knows that the situation is special, so he did not raise objections.

"Knowing the factory director, I'll arrange it in a while. Zhao Ke nodded.

The remaining four cars were quickly installed one by one, and after the test test, all four cars were able to start, shift and drive normally!

In this way, the verification of the clutch performance will also get the results, and then as long as the friction plate is no longer burned out in the road running experiment, then the newly designed clutch will fully meet the requirements of use, and the subsequent vehicle assembly can all be switched to this clutch.

"Why don't I see you go out today? ”

It was rare to get up so early, but found that Zhou Jingming was still lying on the bed, so he simply sat at the head of Zhou Jingming's bed and asked curiously.

Zhou Jingming covered his head in the quilt and didn't want to speak.

"Hey, like an angry little daughter-in-law. Tell me, I'll him!" Daxun is not happy, this Nima dares to touch his person?

"Can't you let me sleep peacefully? I'll rest for the past two days!" Zhou Jingming sat up suddenly, closed his eyes, and looked like he had nothing to love.

The results of the road running experiment have not yet come out, and the clutch design has come to an end, so Zhao Ke specially gave Zhou Jingming a two-day vacation to let him have a good rest.

He Yingxun suddenly realized, "It turns out that it's a holiday!" ”

"Why don't you accompany me to the movies today, I'll have a treat! I always feel like a discount when I watch a movie with those guys who don't have the quality. Da Xun suddenly grabbed Zhou Jingming's hand with a look of anticipation.

Zhou Jingming pulled his hand away, "Don't go, I'll go to the library to read books later." ”

"Okay! You kid is okay! Lao Tzu is helping you buy food and take off your shoes, let you accompany me to watch a movie, I tell you, change me, let alone accompany you to watch a movie, I am willing to eat, drink and sleep together, I don't know what to do!"

Zhou Jingming didn't bother to care about him, he woke up anyway, so he just got up and washed, and prepared to go to the library to have a look for a while, he got his library card a few days ago, but he didn't have time to go, and now he is finally free.

"I'm leaving, why don't you go to the library with me?" After cleaning up, Zhou Jingming asked with a smile.

Daxun didn't even look at it, and looked at the roof with a pair of sunglasses.

Zhou Jingming shrugged his shoulders, and then walked out of the room, as soon as he went out, Da Xun's voice came,

"My sister cooks at noon today, you ...... My sister's cooking is none of your business, you can go to the cafeteria by yourself, stinky old nine!"

"I heard that! I'll be back soon. Zhou Jingming laughed.

After breakfast, Zhou Jingming walked to the factory library. The library was newly built last year, although there are not many books in it, but the environment is good, and there are not many entertainment projects at that time, many young people are willing to go to the library to read books, and sit for half a day.

Because it was working hours, there were not many people in the library, but there were many elderly people sitting there with reading glasses reading glasses reading books. Zhou Jingming walked in gently, found a seat and put down his bag, then walked to the bookshelf and began to look for books.

Since he came to the library to relax, Zhou Jingming naturally did not look for professional books to read, but to find some so-called "idle books", but from the first bookshelf to the second shelf, Zhou Jingming did not find any good-looking books.

The books on the shelves are basically books published in the seventies, and new books in recent years are rarely seen, Zhou Jingming bent over, looking for them row by row, and when he came to the third shelf, as soon as he looked up, he saw a book that he had long wanted to read.

"Gone with the Wind", published by Zhejiang People's Publishing House in 1979, is called "Poems of Wind and Wood" in Japanese translation, a very meaningful translation.

Zhou Jingming smiled and reached out to take it, and at the same time, on the opposite side of the bookshelf, a slender jade hand also reached out to the book, and the two of them held a corner of the book at the same time.

Feeling that there was someone on the other side, Zhou Jingming looked up curiously, and through the gap in the bookshelf, he finally found out who the person opposite was, it was He Yingqing, who he hadn't seen for a long time!

At this time, He Yingqing also saw Zhou Jingming, and the two of them spoke out almost at the same time,

"Is that you?"
