If the car does not have a front end, the engine basically has to be installed under the seat, and some van engines in later generations are installed in this way.

But Luo Cheng does not produce vans, but electric vehicles similar to those of the old man. Electric cars involve less things, no engines, and small motors. There is no need for a fuel tank.

Therefore, there is no need for the front of the car, and the height of the interior space is sufficient.

As soon as Luo Cheng shouted in the workshop just now, an apprentice who was close to him and was currently not alive came over. A little farther away, when he saw someone coming, he didn't come forward again.

The engine is the smallest model of the automobile type, and there are fuel tanks and water tanks. Luo Cheng asked the apprentices to move one of each. How to place the open space in the position you envisioned.

At this time, Luo Cheng was a little big, and the body had to be heightened according to the initial design. Because it is not heightened, there is not much separation between the engine and the seat. The engine is still vibrating a lot, so we have to add springs under the seats to absorb the shock.

Lowering the chassis, that will affect the performance, maybe a stone twenty or thirty high on the road surface will not dare to drive over.

"Okay, let's put it down first, any of you go to find Director Zhang, just say that I have something to look for him."

"Team Leader Luo, I'll go."

An apprentice responded, carefully putting down the engine in his hand, and then trotted out of the workshop to call the factory director.

Seeing that the apprentice ran out, Luo Cheng suddenly felt as if he was a little strange, According to the previous situation, if there was something, he would personally call the factory director. Although I am calling others now, I want to have more time to think about the problem.

The ringgit, must have been used to being with Director Zhang, and he also learned the way he commanded others when he had something. This behavior ~~ seems to be a bit cool, but it is not deliberately to call others for the sake of coolness, but instinctively feel that their time and work are more important, and they need to call people to cooperate with themselves.

It didn't take long for the factory manager to come with the apprentices.

"Little master, I'm sorry for you, factory director, I have a few questions I want to ask you."

Luo Cheng first thanked the apprentice who ran errands, and then said to Director Zhang.

Seeing that Luo Cheng was holding the drawings and things placed on the ground, Director Zhang nodded, if it was a design problem, he felt that Luo Cheng would ask in vain, and if it was something else, he should be able to give a reference. Now it's time to discuss work issues, and Director Zhang is also serious and listens to what Luo Cheng wants to ask.

"The problem is this, when we first designed this block car, we wanted to put the engine and other equipment under the seat. However, it did not take into account a problem of heat dissipation and vibration, but if it was added, the height of the body that was designed at the beginning was that people who were a little taller might have their heads on the roof of the car. But if the body is heightened, the wind resistance will become greater, and the special is when the wind blows and turns. ”

Luo Cheng asked his own question, which was not a design problem, and Director Zhang understood it when he heard it. The engine is going to spin for a while, and you can see how hot it is when you touch the hood.

But this picture is not directly on the engine.

"How tall are the compartments and cushions you're writing about?"

"The cushion is more than ten centimeters, the compartment is also more than ten centimeters, and the shock absorbing spring is installed in the cushion, and the distance between the compartments is high, so the temperature will not be too hot."

"It's all reduced in size, can it be useful."

"It can be useful, but it will be much less effective."

"That's fine, you can't still heat people to death. How does the vibration compare to a tractor? ”

Compared with tractors, we are cars, this can be compared. There is no difference between driving a tractor and driving an engine directly, but it's right to think about it this way, I'm too entangled in comfort, and the cars of this era are not comfortable.

Nowadays, there is no air conditioning in the car, and when it is hot, everyone is sweating when driving, and the car is at most equipped with a small fan, and it is very easy to pour a line out.

However, fans are also in short supply in the market, and there are not many ordinary urban residents who have fans now. When it's hot, the fan doesn't leave your hand, and you just hide in the shade to enjoy the coolness.

If you want the comfort of ringgit, tens of thousands of cars have no air conditioning. I'm only a few thousand yuan, at most it's a little hotter, and I can use it as an air conditioner when it's cold.

I completely drilled the horns, 'solved' the problem of heat insulation and vibration, directly got the steel over, and then transferred a group of people to weld the manual chassis. The body is lightweight, and as long as the welding technology is good, some structures do not need a press to produce at all. Even many parts of the chassis of the car are not monolithic in the first place, some are welded, and some are even connected by screws.

Transfer people, go directly to the machinery factory, or other factories with welders to transfer welders.

In Nghe An, the only way to think of a welder is a machine factory. In other cities, there are rolling mills, shipyards, or construction units for bridge works. But in this place, there is nothing to want.

Fortunately, it is not mass production now, as long as a few people are transferred. When the real car is built, there is no group of welders, don't think about mass production.

The size and structure of the chassis, Luo Cheng began to draw and calculate, as long as the steel materials came, the construction could be started.

One afternoon, Luo Cheng found that it was gone after a casual toss, but he was still satisfied with the progress, at least the problem was not big.

But if you want to pass the road test, you have to get the hydraulic shock absorber out, and the principle of this thing is very simple. It can be said to be an upgrade of the structure of the bicycle pump, and those who have used the pump know that the gas is full, and it is very laborious to press the pump.

The principle of this hydraulic shock absorber is like this, it belongs to a closed pump, the pressure of the air alone will be very large, but the air is replaced with liquid, the pressure will be greater, but because it is a sealing device, it can not be pressed when pressing, and so on to make a few holes in the piston rod, referred to as the flow valve.

If you want a lot of pressure, make the hole smaller, and if you want less pressure, make the hole bigger. The shock absorber is covered with a layer of springs to form a double shock absorption. Moreover, the outer spring is matched with hydraulic pressure to form an automatic pull-back effect.

A car can be equipped with one tire wheel, and a large car, heavy car, or the body itself, can also be equipped with two or more. Therefore, such a thing does not need to consider the size of the car at all, and can be directly produced without a brain. Unless it is a special large vehicle, engineering vehicle or the like, it is better to only customize and produce it separately.

This belongs to the post-processing device, with this, as long as there is no problem with the quality of other parts, road inspection is not difficult. Like a step tens of centimeters high, your current car drives down directly, and the effect of the concussion depends on a spring, which can't remove much force at all, and the driver is uncomfortable, not to mention, the shock force may also be dispersed to the bearing.

The car at the bus station, why do the bearings deform, causing the directional gears to get stuck. The hardness of this bearing material is one aspect, which cannot be solved by current technology. But it also has to do with the fact that the road is not easy to walk and often shakes. If the shock absorber is installed, it can also effectively protect the bearing from direct impact.

Let's just say that a good shock absorber is an artifact for a car. When you are in the cab, you won't feel the slightest bump.

Cube car, as long as the chassis is strong enough and has the blessing of shock absorbers, the body is lighter than the car, Luo Chengcheng does not believe in the car he designed, and he will have to be like other cars, and the road test can not pass several times.
