The technicians of the most high-end R&D room in a tank factory didn't even know about such a famous world-famous professional magazine on tanks! Qin Zhenhua was also speechless, but this is normal, that kind of magazine is in foreign languages, and it is estimated that he can't read it.

"It turns out that the R&D room in our factory is at this level." Qin Zhenhua shook his head helplessly: "It's really sitting in the well and watching the sky, Yelang is arrogant." It's no good to still spray a tank with a hydrodynamic transmission here? ”

I really don't know where the sense of superiority comes from! Qin Zhenhua secretly thought in his heart, if it is a worker on the production line outside, forget it, here, it is the best technician in the tank factory, and it is actually such short-sighted, here, is it the R&D room of the factory I am most looking forward to?

Thinking of this, Qin Zhenhua wanted to give up on himself, go back to the maintenance workshop, at least he had already mingled with the masters there, and after driving away Liu Dajun, life was very comfortable.

"What's good, what's good?" When Du Youwen heard Qin Zhenhua's words, he couldn't help but look at the hydraulic oil he was sprayed all over his body, and his face was indignant: "Our three boards and three rods have won the Stalin bonus, the most typical layout, until now, has been extremely reliable, hydraulic transmission, can it be compared?" ”

If you drill into the cab of the 59 tank, you can find that it is very simple, that is, a few dashboards, and many times when the driver is driving, his head is poked out, and he does not look at the instruments inside at all, and he listens by ear to know whether there is a problem with the engine.

As for the operation, it is also a blind operation, I already know where it is, the so-called three plates, that is, the throttle, clutch, brake, three rods are the left and right steering operation levers, and the gear lever.

This mode of operation is designed to be efficient and reliable, and there have been no problems at all since entering the army.

However, I don't know what's going on recently, I actually want to make a prototype of a hydraulic transmission tank, and I still have to map and copy the hydraulic transmission system of this M48 tank, is it so easy? Just look at the oil stains on my body and you can see how difficult it is.

The people in the R&D room are all bullish, and their technology is the highest.

Du Youwen, like his name, is a literary weapon, not only worked in the workshop, but also went to a junior college, in that turbulent era, delved into technology, and became a pillar of the R&D room.

However, he is really resistant to this task.

Today is already Saturday, and it is said that it is time to get off work in the afternoon, Du Youwen is still busy here, and he is in a bad mood because of technical problems, coupled with a tireless guy like Qin Zhenhua, Du Youwen is fed up.

Du Youwen didn't think there was anything good about hydraulic transmission, the current design is very good, what is worth studying?

I have been holding these words in my stomach for a long time, but I don't dare to say it to Zhu Lao, after all, they are armored forces research institutions, and apprentices like Qin Zhenhua can break and fight, you can talk about it, where is it?

"So, recently in the tank assembly workshop, the running gear of the 69 tank was assembled wrongly, do you know?" Qin Zhenhua asked rhetorically.

"Of course I know, it's not just a good thing you did, and it has also caused the entire workshop to have no bonus." Du Youwen said that there is a relationship with Yu Changhong, of course he knows this kind of thing very clearly.

Qin Zhenhua's brows wrinkled even more, if everyone thinks like this, it means that there is really a big problem with the factory!

It's a pity, I'm a small apprentice, I can't reverse these, if I am the factory director, I will definitely reform with a big axe, such a person with such a thought, the first time to Lao Tzu to get out!

"It turned out to be a good thing that our maintenance workshop did, we should not report it, and then let the 69 tanks in the tank division break down one by one, return to the factory for maintenance, and let our only advanced tank be a weak chicken, regardless of whether he has a war or not, anyway, there is a blame for our maintenance workshop, if it is really a war, then let us repair the workshop and follow the troops?"

Qin Zhenhua's rhetorical question made Du Youwen unable to continue.

"I didn't talk about it, I'm 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 matters, the running mechanism of the 69 tank, how did it come about?" Qin Zhenhua asked.

"The 59 tank has been changed."

"How?"

"Increase it, increase the strength, the engine power of the 69 tank is greater, the original gear is not good, just use the high-strength gear."

"Then why don't you add volume?"

"Because there's no space." Du Youwen said: "I said 59 tanks, why are you talking to me about 69 tanks?" I'm talking about the good or bad of the two driving methods, don't change the topic for me! ”

"Are you really stupid, or are you pretending to be stupid, isn't the answer coming out?" Qin Zhenhua asked.

Foolish? You're stupid, believe it or not, I'm going to beat you! Du Youwen's anger also came up.

"The walking system of the 59 tank can not be inherited, yes, its design is very reliable, the failure rate is low, however, its design is too primitive, needless to say that this design only has a specified steering radius and a braking steering radius, with the increase of vehicle speed, the specified steering radius can not meet the steering needs of the vehicle at high speed This most chicken rib setting. Speaking of its structure, in the gear set of the fixed-shaft gearbox, the large-diameter gears are located on two parallel shafts, one in front and one in the back and one horizontally, which leads to the large length of the gearbox. Therefore, if you want to increase the strength and increase the range of the reduction ratio, the fixed-axle gearbox must continue to increase and increase the weight, which is not conducive to maintaining the volume and weight advantage, and our 69 tank has to take the road of strengthening and requiring the right teeth. ”

Qin Zhenhua said it all in one breath: "This is still the engine only increased from 530 horsepower to 580 horsepower, this kind of gearbox can't keep up, if the horsepower continues to increase, like the West, to 1200 horsepower, or even 1500 horsepower, the existing gearbox, can it still be used?" ”

The reason why we want to study the Western transmission system is because the Western transmission system is more suitable for high-horsepower engines, and this kind of design of our own has come to an end, and it cannot be continued at all!

Qin Zhenhua has not participated in the research, of course I don't know, the transmission system of the 69 tank, when it was designed, it was very difficult, I didn't think it before, but after a research, I found out how ingenious the design is, there is no way to change it, and it can't be installed after changing.

"Don't tell me that we can fight the world with 59 tanks, and our tanks will forever hover at the level of more than thirty tons! Without weight, what do we rely on to increase protection, and on what basis to increase firepower? Horse-drawn carts? Only a more advanced hydraulic transmission system can support the development and progress of our tanks. ”

Qin Zhenhua said everything he thought of in one breath, his voice was still getting louder and louder, and he was about to roar in the end, feeling very comfortable, if the entire R&D room of the factory was a person who thought like Du Youwen, then he was really not interested here!

"Well said!" Just then, suddenly a voice came from the tank's side.
