Ordinary tanks use torsion rod suspension, which is the most mature method after years of development. A steel torsion rod is directly inserted horizontally at the bottom of the vehicle body, and each side is twisted into a shaker.
The tank's load-bearing wheel is installed on it. When it is bumped up and down, it can be buffered by twisting the torsion rod. It has a simple structure and good effect. It is used by a large number of armored vehicles. Even tanks such as Leopard-2 and M1 are used.
They are all torsion rod suspension, and it can be said that it is the most suitable method of hanging tanks.
However, with the continuous advancement of technology, the torsion rod suspension will become more and more outdated, and the tall and high-end liquid suspension has gradually entered the vision of tank designers.
No matter what suspension it is, its purpose is the same. When the tank is moving, the load-bearing wheels must bump up and down, while the suspension is to reduce this bump and make the tank body more stable. The torsion rod suspension is the elasticity of the torsion rod.
The liquid gas is suspended by the hydraulic cylinder. The oil in this hydraulic cylinder is responsible for transmitting pressure and elastic shock absorption. Generally speaking, nitrogen is used.
The most important purpose of this liquid air suspension is to improve the smoothness of the vehicle and its impact resistance. If it only works on a stable road, there is no difference between the two, but if it goes into a continuous ups and downs in the wild, liquid air will be
The advantages of suspension are reflected.
During movement, air, an elastic medium is easily compressed, that is, the suspension device can absorb more energy, and all of this energy is stored, and it will be released when the suspension is lengthened. This way, it will be done.
Buffering can provide good shock absorption and make the tank more stable.
Moreover, with the further development of technology, this liquid air suspension can not only have a good shock absorption effect, it can also adjust the content of the internal gas of the suspension, similar to the central deflation system of the tire. After such operation,
You can change the damping of liquid air suspension. When you are no load and heavy load, you can change the softness and hardness of the suspension by charging and deflation. When you are no load, you will feel more comfortable and you will feel more hard when you are heavy load.
Support the weight of the tank.
At the same time, through this system, the pitch angle of the tank body can also be changed. The tank has multiple load-bearing wheels. The suspension in the front and the suspension in the rear can be different, so the tank can lie down or tilt its head, or even tilt its left or right
In this way, it is convenient for the tank to hide itself based on the terrain.
It can be said that liquid air suspension is high-end, but at the same time, its technical requirements are also high.
Back then, when I was working on a 122 tank prototype, the first machine factory used liquid suspension. Unfortunately, because of insufficient technology, I had to give up. The biggest problem was of course the oil leakage.
Only industrial powers have this ability. In the 1970s, many countries used liquid suspension, but few of them were successful in the end. As for the moment, Challenger 2 and Leclerc tanks both used
Liquid air suspension, however, the liquid air suspension they use is fixed height and does not have the ability to adjust the height. It is just a equipment for driving and fire stability.
The Swedish S tank, a series of tanks from the island country, are representative of adjustable liquid suspension tanks.
Especially Sweden, their country is mountainous, so they created an extremely unique S tank. This tank has no turret, which greatly reduces the height. At the same time, the tank gun cannot move, so when aiming
, it can only move the vehicle body, so its left and right tracks can be fine-tuned to change the direction of the tank gun. At the same time, the liquid suspension it uses can be changed in height, so that it can be used to adjust the pitch angle.
However, there is only this one in the world, and this kind of tank did not continue to develop. Later, they returned to normal tracks. They directly purchased the Leopard-2 tank, which used their own personal experience to illustrate the design.
It is unreliable.
As for the island countries, they have always used liquid-air suspension tanks, and the current tall 90 tanks are the same. After all, their industrial processing capabilities are superb, and other countries cannot get through.
For ordinary tanks, simple structure and solid and reliable are the hard truths. Therefore, it can be foreseen that for a long time, torsion rod suspension must be the most important suspension method for tanks. However, if you stop, then
It is not possible either. A high-end liquid suspension must be done by the first machine factory. Just start with this low-level artillery medium-sized universal chassis.
Since it is the second generation, it must have technological progress compared to the previous generation. Qin Zhenhua is absolutely unwilling to sell dog meat with the title of sheep. The transmission system needs to change, the engine needs to change, and the suspension system needs to change. In this way,
, it is worthy of the second generation's statement.
"Unlike the era when we used to build 122 tanks, now our precision machining technology has improved greatly." After hearing Qin Zhenhua's proposal, a technician finally spoke: "We used to build liquid suspension.
At the time, oil leakage is always because of insufficient processing accuracy. Now, our technology has improved, and it will be easier to develop such suspensions. Technically speaking, the problems encountered should be smaller, but Qin Factory
Long, is this project owned by our machine factory or the superior?”
This problem is crucial. One machine factory is making money now, and there is a lot of funds on the books. However, independent research and development is a cost-effective way. The current one machine factory does not have the strength, and the one machine factory is independent.
The research and development projects are limited to changing the 59 tank into infantry fighting vehicles. The largest foreign trade project of the first aircraft factory, Khalid Tank, was built with Lao Ba, and someone provided funds.
If you want to independently develop a second-generation chassis, there are a lot of new technologies. If you continue to develop it, it will definitely require a lot of funds. If the superiors do not grant funds and rely on the one-machine factory to do it themselves, you may not be able to afford it.
ah.
Hearing this, Qin Zhenhua still calmly said: "Now, there is a chance, that is the Doyle M1 self-propelled air defense missile system. This system must be copied in China. If we can take over the chassis of this system, then
The country will invest a certain amount of money. Of course, even without the investment of the country, our machine factory can do it ourselves. I believe that it can definitely become a hot item in the international market, and our machine factory must also go to the world
