Qin Zhenhua is a very special person, and he must not be judged by ordinary people's thoughts, which is clear in Mia's heart.

He made so many things, obviously to assemble heavy trucks, and moreover, he also did it in their heavy truck branch, but, strangely, there was no cab for heavy trucks!

Many people think that the shell is not important, but the three major pieces are important, but in fact, this is not the case.

An excellent heavy truck will inevitably have a beautiful and atmospheric cab, which is like a person's appearance, which can give people a first impression, so that people can fall in love at a glance, in a word, sell well.

At the same time, there are other functions, the cab is the driver's living and working place, the comfort level directly determines the driver's working mood, advanced heavy trucks, has begun to use airbag shock absorption cab and airbag seats, quite comfortable, so that the driver driving becomes a kind of enjoyment, rather than torment.

Not to mention anything else, take the future generations as an example, a seat of an imported heavy truck, the price can buy a small QQ.

Finally, it is reliability, although the cab looks simple, it is also composed of various parts, simply put, a hand-cranked glass window, if the quality is not qualified, three days and two ends can not rise, it will also bring great inconvenience to the driver, not to mention that with the development of technology, there are more and more parts of the cab, a small problem, it is enough to torture people.

The cab of the Mercedes-Benz heavy truck is also quite advanced, the highest level in the eighties.

It seems very simple, in fact, the knowledge is very large, just the paint spraying of the cab, there are many processes, a machine factory does not have these supporting equipment, the corresponding cab, can not be done.

Although I have seen a hand-built cab before, but that thing is just to see, and cannot be treated as a mass-produced product, and later, that cab seems to be gone.

Now, what are the big moves of a machine factory?

Schultz thought for a long time and said, "Mia, why don't you take me and let's go to a machine factory?" ”

The relationship between Mia and Qin Zhenhua is very good, and in the development of 10,000 tons of hydraulic presses, it is also meritorious, so although it is a military unit, the supporting automobile branch is a military-to-civilian project, but it does not restrict Mia's entry and exit, if you want to bring Schultz...

"Well, I haven't been there for a long time, but the first machine factory has been very busy lately, maybe they will implement some control, so we may not be able to see it for sure." Mia said to Schultz.

When the two came to a machine factory, it was already April, the capital had already returned to the earth in spring, everything was recovering, and the grassland city was still carrying the cold snap of winter.

The winter on the grassland is long, the weather in the early morning, it seems extremely cold, and the mouth exhales white air, the two came to the automobile branch of a machine factory, showed their identities to the gatehouse, and asked to enter.

"I'm sorry, our automobile branch is currently undertaking a military production task, so outsiders are temporarily prohibited from entering." The porter stopped the two and apologized: "Lady Mia, I'm sorry. ”

Military-industrial production tasks?

Could it be a military truck? No, military trucks also need to be mass-produced, and they also need to be wheelhouses, besides, isn't this a military-to-civilian project?

Just as the two of them turned around to leave, a familiar sound came from inside the factory.

Diesel engine, high-pressure oil pump, when pumping oil, it is this kind of sound, the clearer it is, the higher the quality of the oil pump.

Schultz and Mia both turned their heads to look at a car moving on the road over there.

Suddenly, everything suddenly dawned.

Military armored vehicles! Wheeled armored vehicles!

The pattern of the thick off-road tires and the angular shape make it look like a world-popular look, and then, if you look closely, you can find something.

The inside of the off-road tires, the part of the wheel, the central axle head, looks quite clear, although there is no casting logo on the surface, he can also see that it is the axle head of the Mercedes-Benz axle, and most importantly, on the axle head, there is a horizontal thin tube, that arrangement, you can know at a glance, it is Mercedes-Benz's exclusive patented CTI/DS, tire central deflation system!

For off-road heavy trucks, one weapon is the differential lock, and the other weapon is the tire central inflation system!

When the tank is moving, according to the different appearances, it is necessary to adjust the tightness of the tracks, on the highway, it must be tighter, otherwise it is easy to fall off when turning, and in the field, it should be looser, otherwise, once it presses something sharp, the tracks may be pulled off.

Therefore, a tank crew is a manual job, and one sortie may go up and down many times to adjust the tightness of the tracks.

Wheeled vehicles, driving on the highway, the air pressure is higher and more fuel-efficient, in the field, the air pressure is lower, and it will not be uncomfortable to bump, and in the desert, it is necessary to adjust the tire pressure.

If you rely on manual adjustment, it will be very troublesome, so, during World War II, the central tire deflation system began to appear, and at that time it was mainly prepared for vehicles in the desert.

Later, the Soviet Union and the United States began to popularize this system in military vehicles. It's very mysterious, but it's not particularly difficult, that is, at the head of the axle, a trachea is drawn out, which is connected to the tire, so that the tire pressure can be monitored and adjusted at any time.

Even if the tire has a nail in it and starts to run off, you can keep pumping it inside, and you can continue to drive at low speeds.

Anyway, heavy trucks use air brakes, and heavy trucks come with air pumps.

However, this system is also complicated, the tires are rotating, the axle head is rotating, the air pipe in the axle head is not moving, and the sealing is quite a test of technology.

Each country has adopted its own methods, and Mercedes-Benz began to study this technology in the seventies, and in the early eighties, it was widely used in Mercedes-Benz's off-road heavy trucks.

Who would have thought that now it would actually appear on the other party's vehicle!

The other party has copied all the technology of Mercedes-Benz axles to surveying and mapping! Even with this set of central tire deflation system that Mercedes-Benz is proud of, it was copied and installed on their wheeled armored car!

This technology is originally interoperable.

"What about Qin Zhenhua? What about your Qin Zhenhua? I want to see him, I want to see him! Seeing the car passing by, Schultz finally couldn't help it, and shouted loudly towards the porter.

At this moment, Schultz could no longer control his emotions.
