"This R&D room is not grandstanding, making something new, fooling the leader, and you can come in casually." Du Youwen continued: "We are here, that is engaged in research and development, that is to be down-to-earth, just rely on cleverness, useless, hey, you still don't leave?" Are you waiting for me to call someone from the security department to come? A lot of equipment here is classified, if you don't have that level, don't look around. ”

At this time, Du Youwen, the wrench in his hand, was shaking back and forth, as if he was dancing a sword, he was slightly taller than Qin Zhenhua, he could have looked down at Qin Zhenhua, but now he was looking up at the sky.

That attitude is obviously not welcoming to Qin Zhenhua, this is not a cat or a dog can come. What if you are an apprentice, even if you win the first place in the skills competition? Not by tricks?

"Yes, if you want to develop an advanced hydraulic transmission system, you have to be down-to-earth, standing high, but you are high-eyed, and you can't do it." Qin Zhenhua faced Du Youwen's provocation, and replied firmly: "If you are not down-to-earth, needless to say that you have developed a new one, even if you dismantle someone's one, you can't put it back." However, our R&D room, it shouldn't be so bad, it should be no problem to install it back, but I don't know if there will be a fault, hehe, look at that oil, it's sprayed, right? If you still want to dismantle other people's transmission systems, you will disassemble them or not. ”

Du Youwen's face immediately darkened, and now, Qin Zhenhua can see this M48 tank when he is outside, but if he is a layman, no one knows where it is advanced at all, but the current Qin Zhenhua directly mentioned that he was going to dismantle someone's transmission system!

Moreover, what they said is conclusive, they will disassemble and not install, that's right, they just can't install it back! Of course, it's not that you can't put it back, it's definitely going to be able to be installed, but after you put it on, it just can't work properly, it's not oil leaking, or you can't walk normally, and I've been tossing the equipment here since the morning.

"It's still a secret, not to mention anything else, the M48 tank, which has been used on the battlefield for so many years, what secrets can it have? I don't know how many times each issue of the International Tank Magazine has been published. It doesn't match our 59 tank shoes, but its hydraulic operating system really has two brushes. Qin Zhenhua said that he didn't care, in fact, there was really some expectation in his eyes, he had only seen it in magazines before, but this time, he could really do it, take it apart and take a look, it would be exciting!

Compared with domestic tanks, it is the most advanced, that is, the hydraulic operating system!

The maneuvering of the tank is not easy.

The operation of wheeled vehicles is very simple, turn the steering wheel, and control the wheels in front, so that you can change direction, but tracked vehicles do not have front and rear wheels, that is, tracks on both sides, what to do?

This needs to control the different speeds of the tracks on both sides to achieve differential steering, until now, the main force of the domestic 59 tank, the use of the simplest mechanical transmission, the use of the way to steer, pull which side of the steering rod, which side of the track to slow down, so that it will turn to which side, just like the crawler tractor.

Although the principle is simple, the operation is quite complicated.

The steering wheel, how much angle you play, how big the turn of the car is, and what about the lever? To what extent, it depends on experience, such as the speed of the vehicle, the gear problem, and the ups and downs of the road surface, such as downhill, the lever is still in the opposite direction, and if it is operated incorrectly at this time, it will overturn.

In the West, the steering wheel steering was realized early, and it can even be traced back to World War II at the earliest, when the German Tiger and King Tiger tanks used steering wheels, which are completely different from car steering wheels, and the trick is that the transmission system is driven by hydraulic power.

Under the steering wheel, in fact, it is a hydraulic valve, how much to turn, how much to give the power ratio on both sides, so as to achieve easy steering, the angle of the steering wheel is small, the steering of the tank is slow, on the contrary, it is quite simple, it can be said that a person who can drive a car, will soon be able to start driving a tank.

However, for a long time, domestic tanks have been in accordance with the development route of the Soviet tank industry, and they will not engage in this kind of light-duty tank at all.

However, Qin Zhenhua is drooling over these devices, of course he knows the great changes brought by this device, only when the tankers are relaxed, can they devote themselves to the battle with better energy!

This captured M48 tank, also using the steering wheel driving method, it uses a CD-850-4 hydraulic dual-flow differential planetary gearbox, the gears are only two forward gears and one reverse gear, it seems to sound very backward, but the advanced is backward, and it is absolutely impossible to just compare the number of gears.

It is simple to operate, quite convenient and practical, the reverse throttle is stepped on to the end, and it can also reach a top speed of 30 kilometers per hour, which is definitely not comparable to the slow snail crawling of the Soviet tank series, moreover, it is dual-flowing, and the hydraulic oil can flow in both directions, that is, the tracks on both sides can be rotated forward and reversed on one side, so that the function of turning in situ can be realized!

The 59 tanks of their own side can only be one side of the track does not move, and the other side of the track rotates around the midpoint of the opposite track as the axis, this gap, in actual combat, is reflected in the rapid pointing of the tank gun to the target.

In World War II, the ace Tiger tankers did just that, shaking the turret to rotate while letting the hull turn, quickly and efficiently turn the gun around, and then fire to kill the opponent!

Every time he reads a book and looks at this kind of tactic, Qin Zhenhua is drooling greedily, so he has studied a lot of techniques in this area, of course, he has not seen the actual one, all of them are just talk on paper.

However, the idiom of talking on paper, in Qin Zhenhua's body, it is not a derogatory term, I am knowledge! If you want to be a good tank factory worker, you must not only be able to use your hands, but also use your brain, and you must learn knowledge!

The master likes to rely on experience to do things, but the experience is only for the past, what has been learned, it will, what has not been learned, what has not been contacted, will not, even if it is the research and development room of the factory, it is also like this, the current Du Youwen, here for a long time, the problem encountered is at a loss. As for the old man in front of him, he was studying in it wholeheartedly, and he didn't hear the talk here.

Du Youwen was originally angry because he couldn't repair this thing, but now that Qin Zhenhua said this again, he was even more angry: "From the maintenance workshop, do you know what technology is?" After reading a few issues of the magazine, you feel like you're amazing? Where are the magazines professional? And what is that international tank magazine, how come I haven't heard of it? Besides, what are the benefits of this hydraulic transmission? It's so complicated to disassemble and assemble once, and when it comes to the battlefield, I don't know how many failure rates there are. ”
