"This R&D room is not about trying to show off some new stuff, fooling the leaders, and then you can come in casually." Du Youwen continued: "We are engaged in R&D here, so we have to be down-to-earth.
Yeah, it's useless just to be smart. Hey, why don't you leave? Are you waiting for me to call the people from the security department? A lot of the equipment here is secret. If you don't have that level, don't look at it."
At this time, Du Youwen was holding the wrench in his hand, swinging back and forth, as if he was dancing with a sword. He was slightly taller than Qin Zhenhua. He could have looked down at Qin Zhenhua, but now he looked up at the sky.
That attitude clearly shows that Qin Zhenhua is not welcome. This is not a place where cats and dogs can come. As an apprentice, so what if you win the first place in the skills competition? Isn't it just a matter of trickery?
"Yes, if you want to develop an advanced hydraulic transmission system, you have to be down-to-earth and stand tall, but you have high ambitions and low hands. That is definitely not possible." Faced with Du Youwen's provocation, Qin Zhenhua replied firmly.
One sentence: "If you are not practical, let alone develop new ones yourself, even if you dismantle someone else's, you won't be able to put it back together. However, our R&D room shouldn't be that bad. It should be no problem to put it back together, but I don't know if it will.
There will be a malfunction, haha, look at the oil all over, is it sprayed, right? I want to dismantle someone else’s transmission system, but I know how to disassemble it and not install it.”
Du Youwen's face turned dark immediately. Now, Qin Zhenhua can see this M48 tank outside. However, if a layman, no one knows where it is advanced. However, now Qin Zhenhua directly mentioned it
It's about dismantling someone else's transmission system!
Moreover, they also said it categorically that they can disassemble it but not assemble it. Yes, they just can’t put it back together! Of course, it’s not that they can’t put it back together. They can certainly put it back in, but after putting it back in, they just can’t work normally.
, it’s either oil leakage or unable to walk normally. I’ve been fiddling with the equipment here from morning until now.
"It is still a secret. If nothing else, the M48 tank has been used on the battlefield for so many years. What secrets can it have? Every issue of the International Tank Magazine has been published countless times. It is not worthy of our 59 tanks.
, However, its hydraulic operating system really has two brushes." Qin Zhenhua said nonchalantly. In fact, there was a look of expectation in his eyes. He had only seen it in magazines before. This time, he could actually do it.
Take it apart and take a look, it will be exciting!
Compared with domestic tanks, its most advanced feature is the hydraulic operating system!
It is not easy to control the tank.
The operation of a wheeled vehicle is very simple. Turning the steering wheel controls the wheels in front, so you can change the direction. But a tracked vehicle has no front or rear wheels, just tracks on both sides. What should I do?
This requires controlling the different speeds of the tracks on both sides to achieve differential steering. Up to now, the main domestic 59 tanks have always used the simplest mechanical transmission, using a pull rod to steer. Which steering rod to pull?
The track on that side will slow down, so it will turn in that direction, just like a crawler tractor.
Although the principle is simple, the operation is quite complicated.
The steering wheel, the angle it turns, the car will turn, and what about the pull lever? To what extent you pull it, you have to rely on experience, such as the speed of the vehicle, gear problems, and the ups and downs of the road surface, such as when going downhill, you need to pull the lever
It's still in the opposite direction. If you operate it incorrectly at this time, the car will overturn.
In the West, steering wheel steering has been implemented very early. It can even be traced back to World War II. The German Tiger and King Tiger tanks all use steering wheels. This steering wheel is completely different from the car steering wheel. The trick is the transmission system.
It is hydraulically driven.
Under the steering wheel, there is actually a hydraulic valve. As much as it is turned, the power on both sides is proportioned. This achieves easy steering. If the steering wheel turns at a small angle, the tank will turn slowly, and vice versa. It is quite simple.
It can be said that a person who can drive a car can quickly learn to drive a tank.
However, for a long time, domestic tanks have followed the development path of the Soviet tank industry. They will not build such easy-to-operate tanks at all. Tanks are for fighting, not for enjoyment.
what?
However, Qin Zhenhua is drooling over these devices. Of course he knows the great changes this device brings. Only when the tank crews are relaxed can they devote more energy to the battle!
This captured M48 tank also uses a steering wheel to drive. It uses a CD-850-4 hydraulic dual-flow differential planetary transmission. There are only two forward gears and one reverse gear. It seems to
It looks very backward, but it is advanced and backward. You must not just compare the number of gears.
It is simple to operate, quite convenient and practical. If you press the reverse accelerator to the bottom, it can reach a top speed of 30 kilometers per hour. It is definitely not comparable to the slow snail crawling of the Soviet tank series. Moreover, it is dual-flow, and the hydraulic oil can
Two-way flow, that is to say, the tracks on both sides can rotate forward and reverse at the same time, so that the function of turning in place can be realized!
Our own 59 tanks can only have one track stationary, while the other track rotates around the center point of the opposite track as the axis. This gap, in actual combat, is reflected in the rapid pointing of the tank gun at the target.
In World War II, this is what the ace Tiger tank crews did. They shook the turret and rotated the vehicle body, quickly and efficiently turned the gun around, and then opened fire to kill the opponent!
Every time he reads a book and sees this kind of tactics, Qin Zhenhua is always drooling. Therefore, he has studied a lot of technology in this area. Of course, he has never seen it in practice. Everything is just talk on paper.
However, the idiom "talking on paper" is not a derogatory term for Qin Zhenhua. It means knowledge! If you want to be an excellent tank factory worker, you must not only be able to use your hands, but also use your brain, and you must also learn knowledge.
!
Old masters all like to rely on experience to do things, but experience only refers to the past. Those who have learned it will know it, but those who have not learned it or have not been exposed to it will not know it. This is true even in the R&D room of the factory. Now Du Youwen
, I have been tinkering here for a long time, but the problem I encountered is that I can't find a solution. As for Mr. Zhu in front, he was so focused on studying it that he didn't hear the discussion here at all.
Du Youwen was originally angry because he couldn't repair this thing. Now that Qin Zhenhua said this again, he was even more angry: "You are from the maintenance workshop. What do you know about technology? Read a few issues of magazines and you will know
Do you think you are great? Where are the professional magazines? Why haven’t I heard of that international tank magazine? Besides, what are the benefits of this hydraulic transmission? It’s so complicated to disassemble and assemble even once, but on the battlefield,
