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

A side three-wheeler was converted into a car-driving operation method. Regardless of whether the operation difficulty is increased or not, for Dai Qianxi, who can drive a car, this is magical.

If you know how to drive, you can do it with basic guidance. At least it is much easier to drive than a car, and at least it takes less effort to navigate. Driving slowly on the street, Dai Qianqian and Luo Cheng had their first formal exchange.

Luo Cheng introduced what he is mainly doing here now. Being the leader of a study group is not interesting. Building a block car is much more interesting, but the two actually do not conflict. A block car requires a steering pump and other things, such as shock absorbers. The members of the study group can act as his assistants. They are engineers. Draw a picture and explain the principles to them, and then wait for the product to be produced in the factory.

Dai Qianqian also introduced her life in the art troupe to Luo Cheng. It was not much different from life in the army, except that the training in the army became performance training. Of course, there is no salary as a soldier in the army, only allowances. The art troupe is a bit like paying wages. Joining the art troupe is actually not much different from joining a job.

During the conversation, Dai Qianqian tentatively asked Luo Cheng whether he supported her to continue to be an art soldier, but she could reassure Luo Cheng that if the two were really together, she would be transferred here and would not ignore it. Home.

Does it support it? Luo Cheng wanted to say that wearing this military uniform would be the strongest uniform temptation in future generations. And let alone men, why do many women actually like men who are soldiers? Many answers are that they think men look handsome in military uniforms.

So of course Luo Cheng supported it, and his support relieved Dai Qianqian's concerns. The people her parents introduced her to were basically young officers, and the allowances were not small. If you are looking for someone like that, I hope she will give up her career as an art soldier and find her a more relaxed civilian job. Raising children is more important.

Luo Cheng would never have thought of supporting the temptation of the damn uniform, and would have made Dai Qianqian have a better impression of him. And his original intention of producing cube cars was just to let other units come to repair shops, so that he could achieve his own vanity and be popular and drink spicy food at the same time.

He didn't know that his work behavior, in Dai Qianqian's mind, became an aspiring young man who made his own contribution to the development of the automobile industry.

The bicycle drove back to the street next to the yard. Dai Qianqian got out of the car. Luo Cheng should have gone to the factory to do some work. And she has been here in Ngee Ann for many days, and the others followed her, but she didn't take them to take them around and see the local customs.

Luo Cheng sat on the tricycle, and the driving position where Dai Qianqian had been sitting just now was still warm. This~~can't be considered~sitting together directly, at least it can be regarded as sitting warmly.

The speed of the third gear in second gear was still less than ten minutes, and Luo Cheng rushed to the auto repair shop.

Luo Cheng came at the right time. The factory director's car had already installed a booster pump and was about to test it.

At noon, the canteen cooked an egg for the welder alone, and he took a ten-minute break after eating and then started working again, so now it is installed and ready for testing.

The front hood of the car was not closed because the power pump occupied the position of the water tank. The water tank was loosened but not removed. The water pipe was stretched and placed directly on the surface without being fixed.

Start the engine, and since the hood is not closed, you can see whether the booster pump is working before driving. The gear tooth belt of the booster pump starts to run as the engine starts. Although it is impossible to see whether the internal working of the booster pump generates hydraulic pressure due to the rotation of the toothed belt, at least the first step was successful.

Team Leader Jiang got into the car, sat in the cab, and put his hands on the steering wheel. According to the principle, with a power booster pump, even if the car is not running, the steering wheel can be turned with very little effort. Without this, a stationary car would be more difficult to steer than a moving car due to the grip between the tires and the ground.

Grabbing the steering wheel, Team Leader Jiang began to spin. Eh~~.

"Are the tires spinning?"

Team leader Jiang stretched out his head. He felt as if the steering wheel and bearing gears were loose. Turning the steering wheel is too easy. Although there is a little resistance, this little effort is nothing. This is when the car is stationary.

"It's turning, Team Leader Jiang. How about it? It's hard to turn the steering wheel."

Li Yiwen, who was standing outside the car watching, replied that the others did the same and told Team Leader Jiang that it had turned.

Effortless? This is no longer a question of effort, but a question of whether the steering wheel should be driven with force. It still didn't start, and Team Leader Jiang didn't retract his head into the car. Instead, he leaned on the window and turned the steering wheel while looking at the condition of the left front tire.

When you turn the steering wheel with one hand, the tires are like your arms, swinging from side to side easily. This is really amazing.

Put it in gear, start it, turn around easily, and drive around the factory. There are two intersections in the large yard in front of the workshop. When you reach the turning intersection, you still need to turn the steering wheel lightly. When the car is moving, you don't need to use any force to turn the steering wheel.

With this smooth feeling, Jiang Changyuan took out a cigarette from his pocket and lit the cigarette while driving. He didn't worry about turning the steering wheel quickly when he encountered a turn.

Have you ever seen how to turn a jeep with one hand? I, Jiang Changyuan, will show you how to do it.

After driving around in a circle, the car returned to its previous parking position. Jiang Yuan got out of the car with some reluctance. He had never driven a car that was so easy to navigate. The excitement was palpable, and he directly asked others to test the car, all the while muttering that it was too easy.

Luo Cheng didn't try to drive it. He didn't know how easy it would be to turn the steering wheel later, so he asked Director Zhang to come and experience it. After all, it was his car that was modified.

Now that it has been successful, Luo Cheng believes that everyone in the team understands the structure and principles. The current experiment is on a jeep. If it is installed on a large car, shuttle van or truck, just adjust the hydraulic strength.

"Team Leader Jiang, the next step is to remove the number of experiments that the team needs to do, and ask the machinery factory to produce ten sets for me first. I am now working on a cube car of my own design. As you know, I use a small steering wheel for the car. You can drive easily with the help of the directional power pump.”

Others went to experience the power-assisted pump car. Luo Cheng walked up to Jiang Yuanyuan and said that this kind of thing is an external auxiliary device. Even if there are things that have not been taken into account, which may cause problems before long, it will not affect the performance of the car.

So after Jiang Changyuan heard Luo Cheng's request, he agreed to Luo Cheng's request without hesitation. What Luo Cheng was doing now, he had already reported to his superior director Zhao He, who had asked him to secretly look after and support Luo Cheng from the beginning. Luo Cheng declared the purchase items himself, and now he arranges them immediately. Otherwise, how could a truck be specially arranged to deliver the accessories he wanted the next day?

"I'll report the situation later. If you need ten sets, you have to produce at least thirty sets. We tested and asked them to make one set manually, which can be considered as help. But if you want so many sets at once, it has to be considered a task order. You need it. If you are in a hurry, you can place the order and have them deliver ten sets first."

Team leader Jiang said that if there are so many, even if there are supporting documents, it cannot be operated like this. The machinery factory consumes some labor, so it's okay to listen to the arrangements here. But this requires dozens of sets. What about the material cost and the efficiency of the factory? Even if it is a state-owned unit, it must be efficient.

Luo Cheng also nodded. Anyway, as long as the space is reserved, the booster pump can be installed even at the end. It can be said that he no longer needs to be involved in the power pump matter in the later stage, but now there is still something for the study group to do.

Asking Team Leader Jiang to go into the office with him, Luo Cheng drew something for him to see.

"This looks like a pump for pumping air into a bicycle."

Looking at the picture drawn by Luo Cheng, the structure is very similar to that of a pump, but there is no pump tube.

Luo Cheng nodded. The structure is the same as that of a pump, but it is a shock absorber device that relies on hydraulic shock absorption to reduce the impact caused by car vibrations. The material cannot be used as a pump.

Looking at the drawings, Luo Cheng began to explain the principle of the hydraulic shock absorber, which is a closed air pump without an air pipe. The air pump is pressurized with air, which is filled with hydraulic oil. There is another spring device on the outside, double shock absorption, which is guaranteed to be many times stronger than the current single spring shock absorption effect.

And this thing was still used in cars abroad five or six years ago.

This is another technology to catch up with. It has only been used abroad for five or six years, and China has caught up. We must know that many industrial products lag behind those abroad for more than five or six years at home.

It must be reported, and the device is so simple that you only need to test the shock absorption effect before mass production. And according to what Luo Cheng said, this thing can be immediately installed on various car models. Unlike the booster pump, it needs to be installed next to the engine.

The matter has been explained, and the report must be reported. At least a sample of the shock absorber must be made first. This thing has a machine tool. Even if you take it in on the same day, it can be rushed out. There are only a few parts in total. So tomorrow the team will definitely need to go to the machinery factory.
