In fact, the power increase of the automobile engine is the same as the power increase of the tank engine. If the displacement cannot be increased, you can only get more air in the cylinder drum and spray more fuel, which requires advanced ones.
For turbochargers and higher pressure high-pressure oil pump systems, in order to maintain constant oil pressure, a high-pressure common rail system is almost a necessary choice.
Now, what the first machine factory needs to do is to transplant the system used on the tank to the automotive engine. Moreover, since the requirements are not as high as the tank engine, it should not be difficult for the first machine factory.
of.
Hearing Qin Zhenhua's words, Liu Qianjin nodded: "If you provide the supporting facilities, we can accept it."
For Jiefang Factory, they were originally a Chinese card factory, but they could not only do Chinese card, and they might also move towards heavy trucks in the future. Therefore, they need a larger engine, with an existing more than 200 horsepower.
The engine needs to be increased to more than 300 horsepower. If the first machine factory provides technology to solve these problems, they will of course be undesirable.
Liu Qianjin has seen this prospect. They will improve the performance of their engines, so that in the future, they will have a suitable engine for producing heavy trucks.
Liu Qianjin immediately agreed. As long as the technical support of the first machine factory, there is no problem in improving the engine's power. He only purchased components such as high-pressure common rail system and turbocharger. The main body of the engine was produced by himself.
In this way, they can accept it.
"Let's talk about the three major items first. After talking about the engine, it's the gearbox. We believe that an advanced military truck needs an automatic gearbox." Qin Zhenhua continued to introduce his own point of view, when he threw this idea away
After coming out, Liu Qianjin was stunned again.
Automatic transmission?
Jiefang Factory has no technical reserves. Although they produce their own gearboxes, they are all manual gearboxes. Moreover, there is no such thing as automatic gearbox in China at all, right? This is a truck. If you drive a truck, can't bear to change it yourself.
Is it blocked? Especially, this kind of vehicle is for the army. If the car soldiers don’t change gears, is it still a qualified car soldiers?
There seems to be no need for this.
"You can see that all kinds of advanced military trucks in the world are automatically transmitted, which is a trend." Qin Zhenhua continued: "Although the car soldiers can shift gears manually, the automatic transmission can be greatly reduced.
Their operation difficulty is that on the plateau, every time they shift gears, they waste their energy. If they shift gears automatically, it can greatly reduce the physical energy consumption of soldiers. On the battlefield, soldiers can also use more without changing gears.
The energy is used to observe the surrounding situation, so since we want to build a brand new third-generation military vehicle, these technologies are necessary."
Many people who are used to driving manual transmission look down on the automatic transmission and think that automatic transmission is disabled. However, in fact, the market for automatic transmission is getting bigger and bigger because it can make people feel relaxed. Driving is for
Transporting materials is for the sake of convenience of transportation, not for driving, and pursuing the feel of the hand, so go off the track. The car serves people.
The same is true for military vehicles. After strict training, the drivers of the army can drive the military vehicles very smoothly, but those are all labor-intensive, especially when it comes to the plateau, people can walk hard, which can save energy, which is always good.
of.
In the world, military vehicles from other countries have also begun to enter the automatic transmission sequence. Tanks have long been automatically blocked, so this car has to enter the automatic transmission sequence.
At this moment, when he heard Qin Zhenhua's words, Liu Qianjin smiled helplessly: "Yes, it is of course the best to have such an automatic truck. However, we don't have this technology, and we don't have this technology in our country, either.
Only Mercedes-Benz manufacturers have built automatic transmissions used for trucks. Even if we want to purchase them, they won’t sell them!”
Many things cannot be bought with money, and those that can be exported in the West are all backward technologies. Besides, the army will not allow the use of imported parts from abroad on trucks equipped with main equipment, for fear of being choked.
"Who said we were going to purchase it, we are studying this technology ourselves." Qin Zhenhua said: "We use the AMT solution, just add a set of pneumatic shift components to the original transmission. If you do, you can
If I can accept my plan, I can leave it all to us for research and development, or form a team to do research and development with us."
Anyway, a qualified AMT gearbox requires a lot of testing and mastering a lot of data, so that it can become more and more mature, shift smoothly, and adapt to various road conditions. Now, whether it is fully handed over to the first machine factory
, if you still work together to carry out research and development, you can speed up the maturity of AMT gearboxes.
The first machine factory wants to provide technology, which is not just a joke, but the first machine factory can really provide technology! Hearing Qin Zhenhua's words, Liu Qianjin felt his whole body trembling due to excitement and excitement, and he said to Qin Zhenhua.
: "We are willing to form a dedicated team to do research with you!"
Of course he knew that this kind of technology was also of great benefit to Jiefang Factory. Jiefang Factory was moving towards a heavy truck factory. If they wanted to become a world-class factory, they had to have their own technical reserves to become
OK, so they need a high-power engine and an advanced gearbox. Since the first-machine factory is willing to take them together, that's of course the best.
"Next, let's talk about the most important thing." Qin Zhenhua said: "If you want to develop this kind of vehicle, the most important thing is the torque distribution control of the four-wheel drive off-road system and the AMT complex road strategy control. We must let the
It is a completely ahead of the generation so that it can stand out among the many bidding products. Therefore, we need to develop this most critical control system, which will be the key to our successful bidding."
It’s not that it looks more powerful on the outside, but it must be all-round advanced in the inner world. It’s like the big eight rounds of a machine factory. It can win the contract because it has developed an H-type transmission system, leading the other factories. Now
This advanced military truck must also be equipped with high-tech equipment.
Hearing this, Liu Qianjin hesitated for a moment, and then said, "Director Qin, if we make it too complicated, will it reduce its reliability?"
"If we don't innovate, why should the army make up its mind to purchase? Isn't it okay to use the previous ones?" Qin Zhenhua asked back.
