Chapter 968: There is no way out of the nest
Even if it is a car, the longitudinal engine is longer than the transverse engine, look at those luxury cars, BMW, Mercedes-Benz, are all big heads, just because the engine inside is longitudinal, and only Mazda, obviously it is a transverse engine, you have to pursue what shape, make a big long head, squeeze the space of the passenger compartment.
The same is true of tanks, of course.
For a tank, the distance it travels is all weight.
Hearing Zhu Lao say this, Qin Zhenhua could only shake his head helplessly and smile: "This is not in a hurry, right?" If you learn to walk first, it's never too late to run. ”
Meals should be eaten in one bite, and the work should be done little by little, and now, it is necessary to consider changing the longitudinal position to the horizontal position, which requires a large number of problems to be solved, and the engine and gearbox cannot be achieved overnight.
Zhu Lao also smiled: "Yes." This really can't be rushed. ”
What's the use of being in a hurry? Now, the overall design is based on the vertical position, and now the vertical position has become the horizontal position, which means that a lot of it has to be torn down and restarted.
If you only copy the surveying and mapping, you may feel that it is not a big deal, how to change how you want, but since the independent development, all kinds of data have to be calculated by yourself, and the workload is many times larger, of course, the advantage is that because they are all their own, they can change how they want.
This change, it's good to save it for later, as for now, it can only be said that the third-generation tank will be brought out first, and how to change it will be a matter for the future.
"Lately, there's one more thing." Zhu Lao opened his mouth and said: "The question about the big eight wheels, many people are circulating, saying that you have yin Iron Horse Factory, is there such a thing?" ”
Zhu Lao also heard about this matter, when the wheeled infantry fighting vehicle was made by a machine factory, and it became serialized, what was the result? The Iron Horse Factory took it directly, copied the surveying and mapping, and added an axle to it, turning it into a large eight-wheeler.
Originally, at this meeting, the Iron Horse Factory was very confident and took it out to bid, but in the end? actually took the initiative to quit.
At that time, there were many people who were curious, and after the meeting, news from all sides also came, and their big eight rounds encountered a big problem during the test, and they couldn't turn around!
If the power of the car is insufficient and the center of gravity is high, it will see the slope die, but I have never seen the car actually have a turn to die, and it can't be turned!
After Zhu Lao heard about it, he also thought it was interesting, and at that time he felt that the Iron Horse Factory was not authentic, and it was to shade the rhythm of a machine factory.
Qin Zhenhua shook his head: "Zhu Lao, the rumors stop at the wise, how can you listen to their rumors and believe them?" In fact, if you seriously say a word, we manufacturers, fight with each other, what can it mean? We have to be able to fight with outside manufacturers and open up new markets, which is called real ability! ”
Qin Zhenhua wanted to say this sentence for a long time, but he never had a chance to hold it in his stomach.
It's like a big family, a person who is not angry, always looks at his relatives around him, and wants to grab food from others, because he knows that relatives will care about family affection, and will not be ruthless and go out to compete with outsiders? They don't dare!
That's what happened, if it can be summed up in one sentence, it is a nest, a tiger in his own home, and a little sheep when he goes out.
Qin Zhenhua looks down on such relatives.
Although the purpose of holding the International Defense Exhibition this time is to help them solve the problem of selling their products, it is more important to open their eyes and let them see the world, not always thinking about how to target their brother units, how to grab food from the mouths of brother units, begging for help from brother units, and standing higher and farther!
For this kind of situation of fighting in the nest, Qin Zhenhua actually hated it in his heart.
A machine factory has never thought about dealing with any domestic manufacturers, a machine factory is thinking about how to grab orders from the world in the fierce market competition!
"yes." Hearing Qin Zhenhua's words, Zhu Lao nodded, he had spent a lot of time in a machine factory, worked with Qin Zhenhua, and also knew Qin Zhenhua's character, for Qin Zhenhua, it was Qin Zhenhua's main goal to sell the products of a machine factory to the world. and the filthy affairs of these so-called brother factories in China, Qin Zhenhua is not very involved.
He stands taller and sees farther.
"So, what's going on with the difficulty of steering on the big eight?" Zhu Lao asked.
At the beginning, at the meeting, Qin Zhenhua once proposed it, which is also the reason why everyone thinks that a machine factory has backhanded the iron horse factory.
He talked about the steering problem, and the result finally proved that the main reason why the Iron Horse Factory did not dare to take out the product was that it was difficult to turn, which was easy to arouse people's associations.
"Just take a look at it and you know that this kind of problem is definitely going to arise with their armored vehicles." Qin Zhenhua said: "They just have no experience. ”
They designed the big eight wheels, probably drawing on the experience of the previous 534 armored vehicles, and distributing the eight tires as evenly spaced as possible.
Because only one row of tires is added, after the eight-wheel tires are evenly spaced, almost one wheel is next to one wheel, and the front two rows of steering wheels are barely separated from the rear driving wheels by enough distance!
As long as you look at the world's mainstream big eight wheels, you can find that there is still a certain distance between the front and rear, so that it can provide enough steering torque, otherwise, the front should be steered, the rear drive wheel should be pushed flat, the side steering torque is not enough, and the differential can not play a role, which will form serious steering difficulties.
How to fix it? In fact, it is not difficult to open the distance between the front and back, which is on the one hand, on the other hand, and on the other hand, it is necessary to think of other ways.
Your own double H drivetrain will not encounter this problem, because it is a two-sided drive method, so when needed, you can even actively reduce the speed of the inside to help steering.
The central drive system of the vehicle, it is inconvenient, just like the Bobcat armored reconnaissance vehicle that the Mercedes-Benz factory is going to participate in the exhibition, even so that the driving wheels behind can be steered, reversed, so that it can provide enough steering torque, and at the same time reduce the turning radius.
Of course, the disadvantage is that the mechanical structure is too complex.
Qin Zhenhua already knew these clearly, but he didn't tell the other party that the kind of behavior of the Iron Horse Factory still wanted to let himself speak out? It's good for them to understand it for themselves.
"Zhenhua, Zhenhua, how about the emblem scheme of this design?" Just then, a voice came from outside.
Shen Xiwen ran in, holding a piece of paper, on which was fiery red.
