As for the current industrial production in China, engines are no longer a problem. Many factories can produce qualified engines. Although there is still a certain gap compared with the international advanced level, they can be used at least.
And there is no big problem with lifespan. However, it has always been a weakness in the gearbox.
Of course, it’s nothing to produce some manual gearboxes. After all, they are just a combination of simple gears. You can easily assemble them and become a qualified gearbox. Don’t force any suction feeling, just use it if you can
Not bad, but with the continuous development of technology, manual gearboxes will sooner or later be eliminated.
This is not because the driver is getting lazy, but because the use of an automatic transmission can greatly reduce the operator's labor intensity. In the past, when operating a car or a tank for a day, the arms would be so tired that they could not be done.
I moved. Although I kept on relying on my usual training and strong will, it was not helpful for improving my combat effectiveness.
So when the 1960s and 1970s, the West had already started to build automatic transmission tanks. This was to reduce the labor intensity of tankers and allow them to have better energy to fight.
In terms of automobiles, this trend is becoming more and more obvious. Advanced cars have begun to use automatic transmissions. Drivers no longer have to worry about shifting gears and can have more energy to take into account the operation of the car. Drivers in the army,
They are all the most skilled people. They operate the gearbox themselves and shift gears are more suitable than computers, but the troops are also constantly developing. It is not easy for newly recruited personnel to reach the level of veteran drivers, but
If it is an automatic transmission, it can greatly reduce the requirements for the operator of the machine.
Everyone knows that this is a trend. One machine factory started to take action very early and has started pre-researching automatic transmissions. Moreover, after several years of research and development, it is now in the state of loading and use. Although it is finally invested in real use.
It's still a long time to use it, but it's a good start.
However, that kind of transmission is only formed by adding an electronic gearshift mechanism after an ordinary manual transmission. If the program is not properly tuned, it will cause serious abrasions. And it will take more than ten years to avoid it.
Only by stopping debugging can you gradually mature.
If you want to talk about vehicles, a mature automatic transmission must be an at-speed gearbox. However, it has never been popularized in civilian trucks because it has many shortcomings. For example, its technical requirements are absolutely the highest, even in the world.
Not many automobile manufacturers can develop it. But if you change your thinking, it might be possible to solve the problem very simply. Wang Erzhu is smart. He has already thought of a solution to the problem, which is to directly transplant the automatic tank.
Transmission.
After years of research and development, the first machine factory has already developed a fully mature and reliable automatic tank transmission. It has also formed a series. Not only on domestic Type 99 tanks, but also on exported tanks, it has also begun to be assembled in large quantities. Of course, it has also begun to be widely assembled.
Yes, the price is also very high.
At this time, when Wang Erzhu talked about this proposal, Qin Zhenhua began to think about it. If we consider it from a technical perspective, the gearbox used in the tank is much higher than the gearbox used in automobiles. After all, the tank engine is 1,200 horsepower.
This new domestic military off-road truck must have strong enough power. But even so, it is estimated that it will not exceed 500 horsepower. Therefore, there is no problem using this technology to build a car's gearbox.
of.
This is simply a step-by-step crush. The only disadvantage is that this thing will definitely not be cheap.
Especially compared with the AMT transmission method, the cost of an at transmission created by this technology may be increased by two or three times.
In this case, is it still competitive? Will the army not consider cost factors when equipped?
It seems that he knows what Qin Zhenhua is thinking, Wang Erzhu said: "The cost mainly comes from R&D investment and the high technology required for manufacturing. But these can be solved, for example, we can cost by expanding the scale.
If that's the cost can be reduced to an acceptable level."
Military heavy trucks are different from tanks. Now that the country is not facing a large-scale border threat, even if the Type 99 tank is developed, it is only a few dozen orders per year. However, if this heavy truck is passed through the army, it will be
Bidding may be hundreds, or even thousands, every year. At such a large scale, the high cost of R&D investment may be distributed.
In addition to these scales, they can also provide supporting facilities for other factories in the future. After all, in China, there is only one manufacturer that develops this kind of automatic transmission. After the research and development, they can not only use it for their own use, but also sell it directly.
If a manufacturer wants to obtain this automatic transmission, it is much more convenient to buy from a machine factory than from abroad. Moreover, the factory has supporting services to help them debug. These are things that foreign manufacturers cannot do.
Arrived.
"In addition to these, that is the question of how to reduce production costs," Wang Erzhu continued: "We plan to purchase the most advanced CNC machine tool equipment. We can directly use advanced equipment to produce, which can greatly reduce the difficulty of our production.
Increase the yield rate of our products. This can also reduce our production costs.”
The production of automatic transmissions is very complicated, with complex pipelines inside, dense, like a spider web, which puts high requirements for processing. Only this kind of machine production can meet the requirements of use.
Hearing Wang Erzhu say this, Qin Zhenhua said: "Did you introduce it from abroad?"
Wang Erzhu shook his head: "Of course not, it was introduced from Brother Qiang. We have told Brother Qiang about this demand before. After several years of technical research, they finally developed the supporting production equipment. Although the purchase price is very high
It's high, but compared to similar products abroad, it's at least 2/3 cheaper. And more importantly, all the programs inside are our own, so there's no need to worry about having a backdoor."
Qin Zhenhua nodded. This is another issue he is concerned about. He hopes to be able to purchase production equipment produced by his country to promote the development of his country's industry. There was a period of time when he had not met Wang Xiaoqiang, and he should go to talk to him another day.
