A technician from the most high-end R&D room in a tank factory doesn't even know about such a famous and world-famous professional magazine on tanks! Qin Zhenhua was also speechless, but this is normal. Those magazines are all in foreign languages. I guess he
I can't understand it either.
"It turns out that the R&D room in our factory is only at this level." Qin Zhenhua shook his head helplessly: "It's really arrogant to sit in a well and look at the sky. It's not good to still spray tanks with hydraulic transmission here?"
I really don’t know where the sense of superiority comes from! Qin Zhenhua secretly thought in his heart, if they are workers on the production line outside, forget it, but here, they are the best technicians in the tank factory, but they are also so short-sighted. Here,
Is this the R&D room of the factory that I'm most looking forward to?
Thinking of this, Qin Zhenhua wanted to give up on himself and go back to the maintenance workshop. At least he had become one with the masters there. After driving away Liu Dajun, life became very comfortable.
"Benefit, what benefit?" Du Youwen heard Qin Zhenhua's words and couldn't help but look at the hydraulic oil sprayed all over his body. His face showed an indignation: "Our three boards and three poles have won Stalin's bonus, which is the most typical
The layout, so far, has always been extremely reliable, can the hydraulic transmission compare to it?"
If you get into the cab of the 59 tank, you can find that it is very simple inside, just a few instrument panels. Moreover, many times the driver sticks his head out when driving and does not look at the instruments inside at all.
You can tell if there is any problem with the engine by listening with your ears.
As for the operations, they are all blind operations. I already know where they are. The so-called three plates are the accelerator, clutch, and brake. The three bars are the left and right steering levers, and the gear lever.
This mode of operation is an efficient and reliable design. After entering the army, there have been no problems at all.
However, recently, for some unknown reason, the higher-ups actually want to build a prototype of a hydraulic transmission tank, and even plan to copy the hydraulic transmission system of this M48 tank. Is it that easy? Look at the oil stains on my body.
, you know how difficult it is.
The people in the R&D room are all very arrogant and their technology is the highest.
Du Youwen, just like his name, was well-equipped with literature. He not only worked in the workshop, but also went to college. In that turbulent era, he studied technology and became a pillar of the R&D room.
However, he was really resistant to this task.
Today is already Saturday, and it is supposed to be time to get off work in the afternoon. Du Youwen is still busy here. He was in a bad mood because of technical problems. Coupled with a guy like Qin Zhenhua who tirelessly fights people, Du Youwen has had enough.
Already.
Du Youwen doesn't think there's anything good about hydraulic transmission. The current design is very good. Is there anything worth studying?
I have been holding these words in my stomach for a long time, but I and Mr. Zhu dare not say it. After all, I am from the Armored Forces Research Institute. With an apprentice like Qin Zhenhua, I can talk about it. Tell me.
, where is the best place?
"So, in the tank assembly workshop recently, the running gear of the 69 tank was assembled incorrectly, do you know?" Qin Zhenhua asked rhetorically.
"Of course I know. Not only did you do a good job, but it also caused the entire workshop to lose bonuses." Du Youwen said, because of his relationship with Yu Changhong, of course he knew this kind of thing very clearly.
Qin Zhenhua's brows furrowed even more. If everyone thinks like this, it means that there is really a big problem in the factory!
It's a pity that I am just a small apprentice worker and can't reverse these things. If I were the director of the factory, I would definitely make drastic reforms. People with such thoughts will get out of here as soon as possible!
"It turns out that it was a good thing done by our maintenance workshop. We should not report it, and then let the 69 tanks in the tank division keep breaking down and send them back to the factory for repairs. Let our only advanced tank lie down and be a weakling, no matter what.
If there is no war, our maintenance workshop will take the blame anyway. If there is a war, then let our maintenance workshop follow the troops?"
Qin Zhenhua's rhetorical question made Du Youwen unable to continue.
"I didn't talk about this. I was talking about the hydraulic drive system and the quality of our current system. Why are you talking about the 69 tank?" Du Youwen began to quibble.
"Of course it does matter. Where did the 69 tank's traveling mechanism come from?" Qin Zhenhua asked.
"The 59 tanks were modified."
"How did you change it?"
"Increase the size and strength. The engine of the 69 tank is more powerful. If the original gears are not good, use high-strength gears."
"Then why not increase the size?"
"Because there is no space." Du Youwen said: "I'm talking about the 59 tank, why are you talking to me about the 69 tank? I'm talking about the pros and cons of the two driving methods, don't change the subject for me!"
"Are you really stupid, or are you pretending to be stupid? Isn't the answer ready to come out?" Qin Zhenhua asked.
Silly? You are the stupid one. Believe it or not, I will beat you up! Du Youwen also got angry.
"The traveling system of the 59 tank cannot be inherited. Yes, its design is very reliable and has a low failure rate. However, its design is too primitive. Needless to say, this design only has a specified turning radius and a control system.
Dynamic steering radius. As the vehicle speed increases, the specified steering radius cannot meet the steering needs of the vehicle at high speed. This is the most useless setting. Speaking of its structure, among the gear sets of the fixed-axis gearbox, the large-diameter
The gears are located on two parallel axes, placed horizontally one behind the other, which results in the length of the gearbox being too large. Therefore, if you want to increase the strength and increase the range of the reduction ratio, the fixed-axis gearbox must continue to increase in length.
Larger and heavier, it is not conducive to maintaining the advantage of size and weight. Our 69 tanks have to take the road of strengthening and require tooth alignment. As a result, the factory did not study carefully, and this problem occurred. "
Qin Zhenhua said it all in one breath: "This is because the engine has only increased from 530 horsepower to 580 horsepower. This kind of gearbox cannot keep up. If the horsepower continues to increase, like in the West, reaching 1,200 horsepower or even 1,500 horsepower, now
Can I still use the gearbox I have?"
The reason why we need to study Western transmission systems is because Western transmission systems are more suitable for high-horsepower engines. Our own design has come to an end and cannot be continued at all!
Qin Zhenhua had never participated in the research, so of course he didn't know that the transmission system of the 69 tank was very difficult to design. He didn't realize it before, but after doing some research, he discovered how clever the design was. There was no way to change it. After changing it, he installed it again.
Not on.
"Don't tell me that we can conquer the world with the 59 tanks. Our tanks will always hover at the level of more than 30 tons! Without weight, how can we increase protection and increase firepower? Small horses and big carts? Only
Only a more advanced hydraulic transmission system can support the development and progress of our tanks. It will be fruitless to remain stuck in the old ways. Think about when we faced the Western guns and cannons, could we rely on broadswords and spears?"
Qin Zhenhua said everything he thought in one breath. His voice got louder and louder, and he was about to roar in the end. He felt very comfortable. If the entire R&D room of the factory were filled with people who thought like Du Youwen, then he would really
I'm not interested in this place anymore!
"Well said!" At this moment, a voice suddenly came from the other side of the tank.
