One side three wheels, was changed by Luo Cheng to the operation method of driving a car, regardless of whether the difficulty of operation is increased or not, but for Dai Qianqian, who can drive a car, this is magical.

If you know how to drive, you will be able to give basic guidance, which is at least much easier to drive than a car, and at least it is effortless to play the direction. Driving slowly on the streets, Dai Xiqian and Luo Cheng really had their first formal exchange.

Luo Cheng introduced what he is currently doing here, and it is not interesting to be the leader of the study group. It's much more interesting to do a block car, but the two are actually not in conflict, the block car needs a directional booster pump, and it also needs others, such as shock absorbers. The members of the study group can act as assistants or something, they are engineers, draw a diagram for them to explain the principle, and wait for the product to be made in the factory.

And Dai Qianqian also introduced her life in the art troupe to Luo Cheng, which is not much different from the life of the army, that is, the training of the army has become performance training. Of course, there is no salary for serving in the army, only allowances. The art troupe is a bit like the nature of paying salaries, and joining the art troupe is actually not much different from participating in work.

During the conversation, Dai Qianqian tentatively asked Luo Cheng, whether she supported her to be a literary soldier all the time, but she could reassure Luo Cheng that if the two were really together, she would be transferred here and would not ignore her family.

Not supported? Luo Cheng wanted to say that she wore this military uniform, and she was the strongest uniform temptation in the later life. And not to mention men, why do many women actually like men who are soldiers, many answers are that they think men are handsome in military uniforms.

So of course Luo Cheng was supportive, and his support dispelled Dai Qianqian's concerns one step further. Her parents introduced her to basically young officers, and the allowance would not be less. If you are looking for such an object, I hope that she will give up the profession of a literary soldier, and will find her an easier civilian job, and raising children is more important.

Luo Cheng would not have thought of the damn uniform temptation to choose support, and would make Dai Qianqian deepen his affection for him crookedly. And his original intention of producing the cube car was just to let other units come to the repair shop, so as to achieve his vanity and at the same time, he could also eat and drink spicy food.

He didn't know his work behavior, but in Dai Qianqian's heart, he became an aspiring young man who made self-contributions to the development of the automobile industry.

Bian Sanlun drove back to the street next to the yard, Dai Qianqian got out of the car, Luo Cheng should be busy in the factory. And she has been here in Ngee An for many days, and other people have followed her, but they haven't taken them around here to see the local customs.

Luo Cheng sat on the top three wheels, and the driving position where Dai Qianqian sat just now was still warm and hot. Is this ~~ counted~ sitting together indirectly, at least it is a warm sitting.

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

Luo Chenglai is also just right, the factory director's car has already installed the booster pump, and he is planning to test it.

At noon, because the canteen fried an egg for the welder alone, and they took a ten-minute break after eating, they started drying, so it is now installed and can be tested.

The front cover was not closed, because the booster pump occupied the position of the water tank, and the water tank was loosened, but it was not removed, and the water pipe was elongated, and it was not fixed and directly placed on the surface.

The engine starts, because the cover is not closed, and before driving, you can see whether the booster pump is working. The gear belt of the booster pump starts running as the engine starts. Although it is not possible to see whether the inner workings of the booster pump are hydraulic due to the rotation of the toothed belt, at least the first step is 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 booster pump, even if the car is not moving, the steering wheel can be rotated with minimal effort. Without this, it would be more difficult for a stationary car to steer than a moving car because of the grip between the tires and the ground.

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

"Are the tires turning?"

Team Leader Jiang stuck out his head, and he felt as if the gears of the steering wheel and bearing seemed to be loose. It's too easy to play the steering wheel, although there is a bit of resistance, but this bit of strength is nothing, this is still when the car is stationary.

"It's turning, Team Leader Jiang, how about it, it's hard to hit the steering wheel."

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

Laborious? It's not a matter of effort, it's a matter of whether to hit the steering wheel or not. Still didn't start, and Team Leader Jiang didn't retract his head into the car, but leaned on the window, playing the steering wheel while looking at the situation of the left front tire.

Hitting the steering wheel with one hand, the tires are like arms, swaying from side to side easily, which is really amazing.

Gear up, start, make a U-turn, and then drive up in the factory. There are two intersections in the large yard in front of the workshop to turn, and when you get to the turning intersection, you still have a light blow on the steering wheel, and the driving car doesn't need any force to hit the steering wheel at all.

This smooth feeling, Jiang Changchang took out a cigarette from his pocket, and lit a cigarette while driving, not worrying at all about not rushing to hit the steering wheel when he encountered a turn.

I've seen a one-handed jeep turn, I'll show you Jiang Changchang's performance.

After turning around, the car drove back to its previous parking position, and Jiang Changchang got out of the car with some reluctance, he had never driven such an easy car to hit the direction. The look of excitement was overflowing, and he directly asked others to test the car, and kept muttering that it was too easy.

Luo Cheng didn't try to drive, how easy it was to play the steering wheel in later generations, he didn't know it, but called Director Zhang to experience it, after all, it was his car that was modified.

Since it has succeeded, Luo Cheng believes that the structure and principle are understood by the members of the group. Now the experiment is a jeep, if you install a large car, a shuttle truck or a truck, you can adjust the hydraulic strength.

"Team Leader Jiang, the next step is to remove the number of experiments in the group, let the machinery factory produce ten sets for me first, I am now working on my own design of the block car, you also know, the car I use a small steering wheel, with the direction of the power pump to drive easily."

Others went to experience the booster pump car, Luo Cheng walked up to Jiang Yuanyuan and said, this kind of thing belongs to an external auxiliary device. Even if there is something that is not taken into account, it will cause problems in a short time, but it will not affect the performance of the car.

So after Jiang Changyuan heard Luo Cheng's request, he didn't hesitate and agreed to Luo Cheng's request. What Luo Cheng is doing now, he has already reported to his superior director Zhao He, and he asked him to secretly support Luo Cheng from the beginning. Luo Cheng declared his own purchases, and the book was now arranged immediately, otherwise how could he arrange a truck to send him the next day for the accessories he wanted.

"I'll report later, if you need ten sets, at least thirty sets will be produced. We test and let them do a set by hand, which can be regarded as a help. But if you want to be so much, you have to count it as a task order. If you are in a hurry, you can place an order and let them deliver ten sets first. ”

Team Leader Jiang said that there should be so many people, even if there are assistance documents, they can't be operated like this. The machinery factory consumes a little labor, and there is nothing to arrange here. But this time it will cost dozens of sets, what about the cost of materials, and what about the benefits of the factory. Even if it is a state-owned unit, it is necessary to pay attention to efficiency.

Luo Cheng also nodded, anyway, as long as the place is reserved, the booster pump can be installed even at the end. It can be said that he no longer needs to participate in the matter of the booster pump in the later stage, but now there is still something to be done by the study group.

asked Team Leader Jiang to enter the office with him, and Luo Cheng drew something for him to see.

"It's like a pump for the bike."

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

Luo Cheng nodded, this structure is the same as a pump, but this is a shock absorber device, relying on hydraulic shock absorption, reducing the impact of the vibration of the car. The material can not be the material of the pump.

In front of the drawings, Luo Cheng began to explain the principle of this hydraulic shock absorber, that is, a closed pump without an air pipe, and the air is pressed in the cylinder, which is filled with hydraulic oil. There is a 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 is still used in cars abroad five or six years ago.

This ~~ is about to catch up with another technology. It has only been used abroad for five or six years, and the country has caught up. You must know that many industrial products lag behind foreign countries for more than five or six years.

It has to be reported, and this device is so simple that it only needs to test the shock absorption effect to be mass-produced. And according to what Luo Cheng said, this thing can be installed with various models at once. Unlike booster pumps, they need to be installed next to the engine.

The matter is explained, and the report is reported, and the shock absorber must at least go to make a sample first. This thing has a machine tool, even if it is taken on the same day, it can be rushed out, and there are few parts in total. So tomorrow I will definitely have to go to the machine factory with the group of people.
