Super Weapon Swap System

Ordinary vehicles rely on the wheels to bear the gravity of the vehicle body and transmit power at the same time. For tanks, the walking device is the crawler, and the wheels are pressed on the crawler, which is the load-bearing wheel.

As for the drive wheel, there are two rows of pinions at the back.

The weight of the tank is transmitted to the load wheel, and the load wheel presses the track, as if it is always walking on the flat ground. This is also the reason for the strong mobility of the tank. No matter what the ground conditions are, the wheels always walk on the track.

According to the weight of the vehicle body, the number of load wheels is also different. Western tanks are self-supporting, similar to the current leopard-2, using seven pairs of load wheels, while these tanks in the Han Dynasty use the structure of five pairs of load wheels.

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

If mass production, the country certainly can't afford it, but now it is only a small amount of equipment. Under the condition of good test performance, production began without any changes to the production drawings.

The silver aluminum alloy shell is glittering. When the car body is welded, all parts begin to be installed on the car body.

Torsion bar suspension is the first one installed at the bottom of the car body.

Tanks have been born for decades. In these decades, the suspension of tanks is also developing continuously.

At first, springs were widely used, but spring suspension took up a lot of space and was self-supporting. Only small diameter load wheels could be used.

Later, after repeated development, we finally found a very suitable suspension method for tanks, that is, torsion bar.

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

Torsion bar suspension is the same principle.

One side of the torsion bar is installed on the side wall of the vehicle body, and the other side passes through the hole of the vehicle body and is connected to the swing arm. The weight load on the wheel causes the torsion bar to twist through the swing arm, and the obtained elastic force is used to support the vehicle 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 the dynamic stroke is very large. Theoretically, the total length of stroke can be close to twice the length of swing arm. There is no problem that other suspension needs to consider the length of spring. In addition, the structure is not very complex and takes up very little body space. Therefore, almost all tanks began to use this suspension.

If its disadvantage is that the torsion bar crosses the vehicle body, it is inconvenient to maintain in the field.

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

He walked into the factory with great strides. Master Zhang wouldn't wait and rolled up his sleeves immediately.

Work!

Without anyone else, he moved down the load wheel on the cart next to him, pushed it to the position of the first torsion bar, aligned it and stuffed it in.

Then, start screwing the screws on it. The thick flower nut must be tightened, otherwise the load wheel will fall down during running.

This is also the most critical step in installing the load wheel.

Master Zhang took a three meter long crowbar from one side, put it on the wrench, and then exerted himself.

One, two.

Soon, sweat came out from Master Zhang's back and forehead. The production line was completely a manual job. Master Zhang worked hard when he was young, but he hasn't done these jobs for several years. Just stare at others every day.

Now, he has felt very hard.

The tighter you tighten, the harder you have to work. Now Master Zhang is hanging in the air. With his physical strength, press the crowbar, tremble, tremble.

"OK, tighten it and install one." Master Zhang picked up the towel hanging around his neck and wiped the sweat on his forehead. Well, he is also old and strong. This one took less than half an hour to install.

By the way, where's Qin Guan?

What is Qin Guan doing?

Take a break. You can't work continuously, or you must be tired. At this time, a circle of people has been gathered around Master Zhang. Everyone knows that the competition between master Zhang and Qin Guan is coming.

Therefore, Master Zhang can only grasp the handrail of the car body and climb up the car body. From this side, you can look high.

What is Qin Guan doing?

Qin Guan was not in a hurry. He pushed a load wheel and stuffed it into the swing arm of the torsion bar. Then he sleeved the big nut a few times and pulled something from the side.

That thing looks very special. Some of it looks like an air pick used in the mine. There is a gas pipe behind it. However, it is used for destruction. What are you doing here?

Qin Guan made no effort. He aligned the tool in his hand with the nut on it and put it in. In front of the tool is a socket, which corresponds to the big nut. It took him five minutes to install the socket.

Then Qin Guan steadily aligned and pressed the button above.

"Hiss, hiss, hiss!" from one end of the tool, a stream of compressed air came out continuously. An electric compressor behind was constantly pumping air, and the tool in his hand trembled.

"Bang bang." under the action of strong compressed air, the socket rotates and completely screws the big nut in almost ten seconds.

The sound was loud, as if a small caliber gun was firing. With its action, Qin Guan's whole body trembled.

Definitely better than when operating a machine gun.

Master Zhang just spent more than 20 minutes and wasted all his strength to screw a nut. He was soaked with sweat. Now, Qin Guan just pushed the tool and screwed it all at once.

Efficiency has increased more than 20 times!

"No, cheating, you're cheating!" Master Zhang shouted immediately. Of course, he knew that if he went on like this, needless to say two hours, Qin Guan finished in an hour. He must have lost. Unexpectedly, Qin Guan was so cunning and cheated with this unknown tool!

Putting down the pneumatic wrench, Qin Guan looked at Master Zhang: "cheating? Do you know the essential difference between man and animal?"

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

"People can make and use tools, but people have smarter brains!" Qin Guan said to the people around him, "see? Because I use new tools, the production efficiency of our factory workers has been improved dozens of times, and the labor intensity has been reduced. In the future, would you like to work with such tools?"
