Super Weapon Exchange System

Ordinary vehicles rely on the wheels to bear the weight of the car body, while relying on the wheels to transmit power, while the tank, the walking device is a crawler, and the wheels are pressed on the crawler. This is the road wheel.

As for the driving wheels, it is the two rows of pinions at the back.

The weight of the tank is transmitted to the road wheels, and the road wheels press on the tracks, as if they are always walking on flat ground. This is also the reason for the strong maneuverability of the tank. Regardless of the ground conditions, the wheels always walk on the tracks.

According to the weight of the car body, the number of road wheels is different. Western tanks have self-weight, similar to the current Leopard-2, which uses seven pairs of road wheels, while these tanks in the Han country use five pairs. The structure of road wheels.

Now, on the production line, the production of the 62 tank has ended. According to the drawings provided by Qin Guan, the 72 tank is being produced. On the production line, some aluminum alloy car bodies have begun to take shape.

If it is mass-produced, the country will definitely not be able to afford it, but now it is only a small amount of equipment. In the case of good test performance, without any changes to the production drawings, the production started.

The silver aluminum alloy shell is shining, and when the car body is welded, various parts are installed on the car body.

The first to be installed at the bottom of the car body is the torsion bar suspension.

Tanks have been born for decades, and in these decades, tank suspensions have also been continuously developed.

At the beginning, there were many applications of springs, but the spring suspension took up space and the weight was heavy, so only small-diameter road wheels could be used.

Later, after repeated development, I finally found a torsion bar that is very suitable for tank suspension.

The principle of this kind of suspension is similar to twisting a towel. Grab the towel at both ends with both hands, and then twist the hand in the opposite direction, and the water in the towel will be twisted out. When the towel is tightened, the hand will feel the towel has a reaction force, this reaction force is the elastic force generated after the towel is twisted.

The torsion bar suspension is the same principle.

One side of the torsion bar is installed on the side wall of the car body, and the other side is penetrated through the hole in the car body and connected to the swing arm. The weight load on the wheel causes the torsion bar to twist through the swing arm, and the elastic force obtained is used for support Car body. This is the principle of torsion bar suspension. It is very simple and takes up very little space.

The characteristic of torsion-bar suspension is that it has a large moving stroke. Theoretically, the total stroke length can be close to twice the length of the swing arm. There is no other suspension that needs to consider the length of the spring. In addition, the structure is not very complicated and takes up very little space in the car body. Therefore, almost all tanks have begun to use this suspension.

If it has its shortcomings, it is that the torsion bar crosses the car body, so it is inconvenient for field maintenance.

Now, all the torsion bars of the Type 72 tank are installed in place under the vehicle. Next, load wheels are installed on both sides of the torsion bar suspension.

Walking into the factory in a stride, Master Zhang would not wait, and immediately rolled up his sleeves.

Let's work!

No one else was needed, he was alone. He moved down the road wheels on the cart next to him, pushed it to the position of the first torsion bar, aligned it, and stuffed it in.

Then, I started to screw the screws on it. The thick nut must be tightened, otherwise the road wheels may fall off during the running.

This is also the most critical step in the installation of road wheels.

From the side, Master Zhang picked up a three-meter-long thick crowbar, put it on the wrench, and then used force.

One click, two clicks.

Soon, sweat came out of Master Zhang’s back and on his forehead. The production line was a complete manual task. When Master Zhang was young, he worked very hard, but it has not been for several years. After doing these tasks, just stare at other people every day.

Now, he already felt very strenuous.

The tighter you tighten, the harder you have to work. Now, Master Zhang is suspended in the air, using his body strength to press the crowbar, shaking and shaking.

"Okay, screw it up, install one." Master Zhang picked up the towel hanging around his neck and wiped the sweat from his forehead. Um, he is always strong. This one, the installation time is less than half an hour.

By the way, what about Qin Guan?

See what Qin Guan is doing?

Rest for a while, but you can't do it continuously, otherwise you will definitely be exhausted. At this time, Master Zhang had already surrounded a circle of people. Everyone knew that Master Zhang and Qin Guan had run over.

Therefore, Master Zhang could only grab the armrest of the car body and climbed onto the car body. From this side, he could see from a high altitude.

What is Qin Guan doing?

Qin Guan didn't rush, pushing a road wheel and stuffing it on the swing arm of the torsion bar. Then, after putting the big nut a few times, he pulled something from the side.

That thing looks very special. Some are like pneumatic picks used in mines, with a trachea dragged behind it, but that thing is for destruction. Why are you here?

Qin Guan didn’t take much effort, aligning the tool in his hand with the nut on it, and set it in. In front of this tool, there was a sleeve, which corresponded to the big nut. It took five minutes to put it in. This sleeve is installed.

Then, Qin Guan steadily aligned and pressed the button above.

"Chichichichi, chichichichi!" From one end of this tool, a stream of compressed air is constantly emerging. An electric compressor at the back is continuously pumping air, and the tool in hand follows Trembling.

"Tom tom tom." Under the action of strong compressed air, the sleeve was rotated, and the big nut was completely screwed in almost ten seconds.

The sound was loud, as if a small-caliber cannon was firing. With its movements, Qin Guan's whole body was trembling.

Definitely better than when shooting with a machine gun.

Master Zhang just spent more than twenty minutes, wasting his whole body strength, and only screwed a nut. His whole body was soaked with sweat, but now, Qin Guan just pushed this tool, and just screwed it all at once. All right.

The efficiency has increased more than 20 times!

"No, cheating, you are cheating!" Master Zhang suddenly shouted. Of course he knew that if this went on, it would take two hours, and Qin Guan would finish it in one hour. He must have lost it. Unexpectedly, Qin Guan It's so cunning, using this unknown tool to cheat!

Putting down the pneumatic wrench, Qin Guan looked at Master Zhang: "Cheating? Do you know the essential difference between humans and animals?"

"What's the difference?" Master Zhang asked.

"It means people can make and use tools, it means people have smarter brains!" Qin Guan said to the people around: "See? Because I use new tools, so let the workers in our factory be more productive , It has increased dozens of times, and labor intensity has been reduced. In the future, would you like to use this tool for work?
