This is a preparatory meeting for the military parade. The goal of the meeting is to select the types. The preliminary plan has screened out about 14 candidate projects. One of them is equipment that has been established but has not participated in the military parade. The second category is that it is possible to
It has been finalized in recent years.
So, even if it is still in the design, it can be taken out in principle. However, if it is only in the design, it is more dangerous. Who knows if there are any design defects and can it be completely solved in the past one or two years?
?
Therefore, at least you have to enter the testing stage.
Almost all the wheeled infantry fighting vehicles of the First Machine Factory have been tested and have been done in actual combat tests. What other problems can be found?
So, what about the Iron Horse Factory?
Iron Horse Factory must be behind the first machine factory. After all, they copied the equipment of the first machine factory and made some self-righteous improvements, so as to treat it as the flagship product in their own factory.
I have to say that it can fool people.
After all, the larger the car body, the larger the space inside. In terms of transporting personnel, it means there is a larger body space, and in terms of loading weapons, it means it can withstand greater recoil.
However, this also means that the design of the car will be more complicated and the more problems you encounter will be.
This is not a simple matter of adding an axis. This axis needs to provide power, not only power, but also steering capabilities.
The steering of the track chassis depends on the different speeds of the two tracks. The steering of the wheeled vehicle depends on the steering wheel of the wheeled vehicle. Generally, the front wheels are the front wheels, and the rear wheels are differential while the front wheels are steering.
Just turned around.
For vehicles with two axles or three axles, there is only one row of steering wheels in front, while for vehicles with four axles, there are two rows of steering wheels.
In later generations, there were many trucks with double-row wheel steering. There were common front four and rear eight in bicycles. The front two rows were steering wheels. When it came to complex ground, even the first row of steering wheels could be directly suspended, using only the second shaft.
Just turn it up, and there are many such tows in the trailer, which is about one ton lighter than a double-row drive wheel vehicle, making it very popular.
However, now, I have never seen a double-row steering wheel vehicle, at least not a single one on the domestic land.
Now, if you want to do the eighth round, the front two rows must be steering wheels. This technique looks very simple, but in fact it is very difficult.
For the two rows of steering wheels in front, the steering lever must be added to drive the steering of the two sets of wheels, which will put forward higher requirements for the steering machine.
After all, the steering machines of heavy trucks are all hydraulically assisted, otherwise the thick tires could not be pushed by the human arm. Now, the components of infantry fighting vehicles have evolved from heavy trucks, which is also
Including the steering machine, it uses a heavy truck steering machine.
In the past, there was no problem in driving a row of wheels. Now, when driving two rows of wheels, the steering torque required will be much greater.
Since you have artificially added a row of wheels, let's talk about it here.
"We have analyzed that if we add a row of steering wheels, the steering torque required must be at least 80%. For military vehicles, it is best to increase the redundancy by 102%.
Ten means that the system that provides support for steering needs to be strengthened. At present, no one in our accessories market can meet this requirement." Qin Zhenhua asked solemnly: "Your side's
Have you ever had any steering difficulties during the test drive of a car?"
"Of course, of course not!" After hearing this, Liu Tiande only felt a chill on his back. They really ignored this problem and thought that adding two levers was enough. Now, when the other party said this, it was really inside.
There will be problems.
But, so what? If there is a problem, just solve it. At this time, you must not admit defeat. If you admit that you have not considered this at all in your design, wouldn’t it mean that you are very immature?
The superiors will not need an immature plan. If they fall into bed during the military parade, it will be great!
However, the other party reminded him after all. After going back, he would improve it. Wouldn’t it be enough?
"Oh, that's good." Qin Zhenhua nodded and said: "In the pre-research, we think that it is easy to turn, not only to work on the steering wheel, but also to cooperate with the driving wheel behind.
”
“Driving wheel?”
"Yes, it is best for the drive wheel to actively differentiate, change the speed of both sides, and match the steering of the wheels in front. Otherwise, there will be wheels on both sides, and it will not be that easy to turn."
Active differential? This means different technical routes! Liu Tiande was already confused at this time. Is this technical problem really that serious?
Liu Tiande finally ended their speech with doubts. The products of the Iron Horse Factory were introduced. In this process, overall, it seems that the first machine factory was at a disadvantage. After all, the first machine factory has exhausted its efforts.
The infantry fighting vehicle project now seems to be completely taken advantage of by the Iron Horse Factory.
However, the last words seemed to be a possible turnaround. However, after all, all these have to be verified later. As for now, let’s continue to hold a meeting!
Other factory representatives began to introduce them, including some meaningful combat equipment.
As for tracked infantry fighting vehicles, a domestic unit already has a Type 86 infantry fighting vehicle. From the appearance, this infantry fighting vehicle is exactly the same as the Soviet BMP infantry fighting vehicle, but it is actually its surveying and mapping imitation.
The products and even weapons are made exactly the same: a special 76mm low-pressure smoothbore gun.
Although there are wheeled infantry fighting vehicles, tracked infantry fighting vehicles are still meaningful. China cannot conquer the world with the old 63 armored vehicles. In the future, this kind of newer infantry fighting vehicle will inevitably be needed.
However, this kind of Soviet products that are imitated by surveying and mapping are not advanced enough!
At this time, Qin Zhenhua was also keenly capturing this information and considering the development direction of the first machine factory. Now, there is a special crawler universal chassis, which has been selected by many weapon systems. However, that chassis is heavy after all,
The engines used are all 59 tanks.
So, is it possible to develop a light track-type universal chassis? After all, this is the best thing for the first machine factory.
Adopting the most fashionable modular design concept can meet the needs of different equipment. If such a chassis is created, it should be more marketable, right?
