Chapter 23 – Single Tube Cradle Structure

Chapter 23 Single tube cradle structure

Seeing Zhao Guoyang’s calm and calm look, Liang Hongjun was secretly surprised, but he didn’t show his expression on the surface.

From the beginning to the present, Liang Hongjun has been shocked by Zhao Guoyang’s various performances, and now he has a little bit of adaptability to his words and deeds.

Seeing that the young man didn’t have the slightest doubt after hearing the word “underbone bike”, Liang Hongjun knew that the other party must know this new type of motorcycle.

A young man who studied mechanical manufacturing at university knows so much about the types of motorcycles, which shows that the other party must be a person who loves to learn, loves to study, and has many talents.

Coupled with the fact that Liang Hongjun noticed the highly technical article in “Made in China” that Zhao Guoyang paid attention to, he attached more importance to this young man than Ma Jian, the deputy who came with him. The factory manager.

Wang Hongxi quickly brought the frame diagram and put it on the table.

Looking at this neat base map drawn stroke by stroke with a drawing pencil, Zhao Guoyang secretly admired it.

In the 1990s, the use of computers had just started, and domestic enterprises were rare at all.

Although the two-dimensional design software AUTOCAD came out as early as 1982, due to the fact that domestic computers have not been popularized, and the Weiruan Windows system has not yet become famous, so AUTOCAD, a giant drawing software, is almost unknown in China at this time. , not to mention the application.

During this period, most manufacturing companies drew their drawings by hand, and Siyang Group was no exception.

This frame drawing is very neat and delicate, even with Zhao Guoyang’s critical eye, he can’t find any faults.

Of course, this drawing is just an overall three-view view, which can only give people a rough idea of the outline of this kind of frame.

If you really want to make a trial production, you still need hundreds or even thousands of parts drawings.

Zhao Guoyang knew in his heart that only when the other party confirmed that his Hongda Machinery Factory had this production capacity, would he contact him further and come up with more parts drawings.

“Comrade Xiao Zhao, this is the frame diagram of the C100 underbone bike that our Siyang Group is about to put into mass production. Please take a look and give me your opinion by the way.” Wang Hongxi said with some pride.

This C100 underbone frame general drawing is the proud work of Wang Hongxi who personally worked on it and led more than 20 colleagues in the technical quality department to design it in three months.

Its design level is so high that even Liang Hongjun, the technical minister, is full of praise.

In Wang Hongxi’s opinion, although this Zhao Guoyang is a college student with serious academic background, he has just graduated after all, and it is pretty good to be able to understand such complicated professional drawings.

As for making comments, it’s just a polite remark.

Different from Wang Hongxi, Liang Hongjun was quite looking forward to Zhao Guoyang’s reaction.

This young man has a maturity and stability that his peers do not have, and he can bring surprises in terms of technology. Such a talent, Liang Hongjun has the idea of recruiting him under his command.

Among the four people present, Ma Jian might be the one who hesitated the most.

As the highest-ranking member of the Hongda Machinery Factory who came to negotiate this time, he certainly hopes to bring more orders to the factory.

But he himself is not proficient in technology, and he only knows a little bit about the frame diagram in his own factory.

Now the frame diagram presented by the other party is far more complicated than the first batch of frame diagrams made for others in his own factory, and Ma Jian is a little bit blind.

At this time, his only hope was pinned on Zhao Guoyang.

Surrounded by three people in the office, Zhao Guoyang was not surprised.

After he took the drawing, he looked at it carefully for a while, and couldn’t help admiring: “Minister Wang, your frame is using a single-tube cradle structure, which is a big innovation in our domestic motorcycle industry. “

Hearing the words “single tube cradle structure”, Wang Hongxi’s face was dull for a while, and his mouth was even more open, looking incredible.

Liang Hongjun next to him was not much better, looking at Zhao Guoyang as if he was looking at an alien.

Ma Jian was the only person on the scene who didn’t understand. At this time, seeing the two ministers of the Technology and Quality Department of Siyang Group in a daze, he couldn’t help but asked Zhao Guoyang in a low voice: “Guoyang, this… what is it?” Call it ‘single tube cradle structure’?”

The leader asked a question, and of course Zhao Guoyang had to patiently explain: “Director Ma, this ‘single-tube cradle structure’ is one of the three main structural types of motorcycle frames.”

“Generally speaking, the frame structure of the cradle frame composed of a single steel tube is called a single tube cradle frame. The other two structural types are the fork tube cradle frame and the double row tube cradle frame. frame.”

“The difference in the use of these three frames is mainly determined by the structural form of the engine. In addition to the size and shape of the engine, it is also related to the position of the engine on the frame. In the final analysis, which car to choose The main purpose is to arrange the exhaust pipe and intake pipe of the engine more reasonably.”

“If a motorcycle uses a two-cylinder or four-cylinder engine, and the exhaust pipes are placed on both sides, then in general, a fork tube or a single-tube frame will be used; if it is a three-cylinder engine, the exhaust pipe will be placed on both sides. In the middle and on both sides, double-tube frames are mostly used; single-cylinder engines occasionally use double-tube frames or fork-shaped tube frames.”

While talking, Zhao Guoyang pointed to the cradle-like structure on the general drawing, and said to Ma Jian: “Look, Director Ma, this cradle-style frame not only has ideal strength and rigidity, but also has a beautiful shape. It has a powerful feeling, which is conducive to the structural layout of the finished car.”

“However, the manufacturing process of this kind of frame requires high technology. As far as I know, only island countries and some developed countries in Europe and the United States use this kind of structure. The frame structure of Siyang Group is used in our domestic motorcycle models. Among them, it should be the first time, and it is a great technological innovation.”

Zhao Guoyang’s explanation was so clear that it couldn’t be clearer. Not only did Ma Jian nod repeatedly, but Liang Hongjun and Wang Hongxi beside him stared at Zhao Guoyang without blinking, as if they were looking at a monster.

After Zhao Guoyang finished speaking, Ma Jian suddenly realized.

He didn’t notice the expressions on the faces of Liang Hongjun and Wang Hongxi, but said flatteringly: “Minister Liang, Minister Wang, your factory is really powerful. It has set a precedent for our domestic motorcycle manufacturing industry. I really admire it!”

After Ma Jian finished speaking, Liang Hongjun and Wang Hongxi didn’t respond. Feeling a little embarrassed, Ma Jian noticed that the two leaders of the Siyang Group were staring at Zhao Guoyang with wide-eyed eyes.

Ma Jian’s heart trembled, and he felt a little bit wrong, thinking that there was something wrong with Zhao Guoyang’s explanation just now.

He quickly explained: “This… Minister Liang, Minister Wang, Guoyang is young, if he said something wrong, please forgive me…”
