When Han Weijun and Liu Dongsheng came back from Li Wenjun, they held a closed-door meeting.
"What do you think?" Han Weijun asked Liu Dongsheng.
Liu Dongsheng pursed his lips: "I want to participate on both sides."
This is probably why Li Wenjun asked them to discuss internally. Because he knew that Liu Dongsheng was too crazy and would torture himself to death if both parties wanted to participate.
In fact, Han Junsheng also wanted to participate in both parties.
Han Weijun didn't know whether to laugh or cry, and said: "How about drawing lots. No matter what you catch, you can't regret it."
Liu Dongsheng: "Okay. No regrets."
Then the two people wrote two notes, crumpled them into a ball, and each picked up one.
Liu Dongsheng picked up a note with "motorcycle" written on it and asked Han Weijun: "Can I come back to see your research and development?"
Han Weijun knew that he didn't want to leave the car factory, so he smiled and said: "Okay. You are welcome to come back at any time for guidance. But I think you may not have time."

Then Liu Dongsheng ordered a few more people to start making motorcycles.
Li Wenjun made a three-part agreement with him: First, no test drive is allowed until all conditions are mature. This condition includes helmet. Second, the first few test drives can only be done in the workshop and not outside. Third, the test drive must be fully protected and the speed cannot exceed 60 kilometers per hour.
When everyone heard this, it was a bit funny: Isn't Li Wenjun afraid that the "second idiot" Liu Dongsheng is not afraid of death himself, but will drag others to death? Just like Tang Monk put a golden hoop on a monkey, limiting his range of activities.
Liu Dongsheng began to think that with the foundation of automobile research and development, the research and development of motorcycles would not be too difficult, because tires, brakes, and engines are all ready-made and can be used with slight modifications.
As a result, it turned out to be completely different.
Not to mention that the appearance cannot be as beautiful as the one drawn by Li Wenjun. What Li Wenjun drew was high-tech. What they made was just an engine added to the bicycle.
If nothing else, let’s talk about the most basic issues. For example, when you stop, stand still.
These two-wheeled things are extremely heavy and heavy, not like a bicycle that can be supported by just one leg.
The three points taught by the math teacher to determine a plane do not seem to be the case. The motorcycle they made fell wherever it was placed, and the direction it fell was different every time.
Only then did I understand why Li Wenjun said that three-wheeled motorcycles are easy to make, but two-wheeled ones are not.
Thinking about it is the key issue.
The amount of steel plates used in motorcycles is small, mainly concentrated in the front half, and the engine is also in the front.
I tried to move the position and size of the footrests, and finally managed to stabilize them, but found that the car was very difficult to control. I called Yuan Leizi, the tallest man in the factory, to push the cart, but he couldn't support it and couldn't push it. After finally pushing it, it was twisted and twisted, and in the end he fell to the ground.
Liu Dongsheng said: "The tires are too small. Make them wider."
The tires are wider and the frame is wider, but the result remains the same and the problem remains the same.
This means that it is not a tire problem, or rather, it is not just a tire problem.
Liu Dongsheng thought for several days but couldn't come up with a solution, so he had no choice but to ask Li Wenjun.
Li Wenjun smiled: "You discovered this problem so quickly? It's not bad. In fact, the main problem is that the engine and the frame do not match. When you make a frame, you must consider the frame's accommodation space, center of gravity, balance and other parameters. Design an engine that suits it. Rather than doing the engine and frame at the same time. The center of gravity and balance of the entire car must be perfectly matched, so that no matter how heavy the car is, it will be flexible and easy to drive.”
Liu Dongsheng suddenly realized: "So the engine cannot be copied from the car."
Li Wenjun said: "You can't copy it, but you can learn from it. Foreign motorcycle factories redesign the size and shape of the engine based on the frame. First make the frame, then design the engine, and then balance the center of gravity. If it really can't be balanced, you have to Fine-tune the frame and engine until they match. And even if you match them well, you must also consider the possibility of large-scale replication. This means that you must have detailed drawings for each component above, no matter who follows them The drawings can all produce a motorcycle with a perfect match of center of gravity and balance. If you want to save costs, first make a scaled-down model out of wood, then make a full-scale model, and then make it out of high-strength steel..."
When they were making cars before, they also disassembled the "Warrior 2" to the smallest detail, and then drew drawings part by part, so that they could be copied perfectly later.
There are no templates now, which means each component has to be designed by themselves.
This is the new challenge! !
This is the beginning!
Otherwise, just changing the sideways car into a sitting motorcycle is not fun at all.
Liu Dongsheng's eyes sparkled with excitement and he murmured, "Fuck it, it's interesting."
After saying this, he ran away without saying hello to Li Wenjun.
"Hey, hey, I haven't finished yet. It takes a lot of time to do this."
Li Wenjun didn't know whether to laugh or cry. Shouldn't ordinary people find it troublesome, frustrated and depressed? This guy is really a freak.
But this kind of person is best suited for research and development. Like to constantly accept new challenges.
Probably Liu Dongsheng was too repressed when he was a child and always followed the rules, so now he likes exciting and innovative things so much.
-----
Liu Dongsheng first borrowed Zheng Yuehua, decomposed the outline drawing drawn by Li Wenjun into a drawing of only the frame, and then continued to disassemble dozens of parts and draw detailed dimensional drawings for each part.
Then I borrowed Chen Zichen, used wood to make a reduced version of each component, and spliced them together into a frame...
Liu Dongsheng didn't have time to go to the car workshop to watch them renovate the car.
However, Han Weijun heard about these things and was so curious that he often ran over to see them.
In fact, he was stuck there, but looking at Liu Dongsheng making models, he couldn't find inspiration.
The engine, frame, and casing of a car are all real materials, and each one costs so much.
In fact, the profit of the 80,000 yuan car produced in the factory is only more than 10,000 yuan. Even if you don't make a penny, you still have to sell it for more than 60,000 yuan. It's still far from the fifty thousand Li Wenjun said.
After much thought, he felt that it was not an option to figure it out by himself. The key was that he did not dare to modify the accessories on the car for fear that quality problems would occur in the future.
During lunch, Han Weijun specially sat next to Li Wenjun and said with a blushing face: "Director Li, can I ask you a question?"
Li Wenjun smiled: "Brother Han is also so polite like them. Just ask if you have anything."
Han Weijun said: "It's about reducing the cost of the car. The car's engine cannot run. Because we tried it many times before we succeeded. We can only optimize it."
Li Wenjun nodded: "Yes, the engine is the heart of the car."
Han Weijun said: "The gearbox, brakes, and safety are all very important, and they cannot be touched..."
Li Wenjun said: "Yes."
Han Weijun pursed his lips.
