"Ahem, let's continue to talk about the specific technology of the tank." Qin Zhenhua just took Wu Qing's words and talked about foreign trade. Now, he finally got back to the main topic and continued to talk about the technology of the tank: "In terms of chassis,
Have we chosen the diameter of the load-bearing wheel?" For tanks, the track is its walking tool, and the load-bearing wheel is on the track. The load-bearing wheel presses the track away. If there is no suitable load-bearing wheel, then
The mobility of tanks will also be greatly affected.
In the past, the 59 tank used a large diameter load-bearing wheel scheme. Because the load-bearing wheel is large, the number is small. Five pairs of load-bearing wheels are enough. Moreover, because the load-bearing wheel is large, the upper support wheels are supported.
All of them are omitted, and the tracks can just hang on the load-bearing wheel. As a result, when moving forward at high speed, the tracks on the upper will occasionally slap the load-bearing wheel below, making an annoying sound.
When it comes to the second generation tank, the medium-diameter load-bearing wheels have been used. The load-bearing wheel has a small diameter, so six pairs of load-bearing wheels were used. At the same time, there are pulleys on it, which has become the current conventional structure.
The diameter of the load bearing wheel is small and there is a lot of space on it, which means that the buffer stroke of the load bearing wheel is relatively large, which can reduce bumps.
"Yes, we decided to reduce the diameter of the load-bearing wheel of the current 99 tank, so that it can have a better buffering effect." The person in charge of this aspect said: "At the same time, according to the weight distribution of our tanks
The distance between the two pairs of load bearing wheels in the front can be slightly widened, while the load bearing wheels in the back can be arranged at equal intervals, which will make our tank layout more convenient."
Generally speaking, there is the main armor in front, the driver's position, and the engine and other things behind. Different equipment and different weights, and the installation position of the load-bearing wheel is also very particular. After so much research
The process is to determine the diameter of the load bearing wheel.
Qin Zhenhua nodded: "Well, then we will follow the diameter we have determined. So, what solutions do we have in terms of suspension?"
"Now, when it comes to high-end suspension, of course, is a liquid suspension. This kind of suspension can be adjusted entirely by the internal oil. It not only has a good buffering effect, but also can achieve the effect of a tank lying down or raising its head.
We have already had mature products in China, but if we consider comprehensive factors, we think that conventional torsion rod suspension will be better.” Speaking of this suspension, someone began to report to Qin Zhenhua again. Liquid air suspension
High-end, this thing has been equipped in tanks in some countries. The front stroke can be shortened and the back stroke can be lengthened, so that the tank can be lowered, not only for performance, but also for practical purposes.
When the tank is fighting in the mountains, if the dive angle is not large enough, then this method can be used to increase the dive angle. For Soviet-style tanks that never bow their heads, this suspension can make the dive angle of the tank gun lower, obviously
It is beneficial.
However, its disadvantages are obvious. This kind of tank suspension is more expensive and more delicate. Even if it has been developed and mature, it may fail. On the plateau, in the desert, in the south, and other places.
, This kind of suspension may fall into trouble at any time.
Once this thing is broken, the tank will not be able to move. The suspension system is the tank's shoes.
Therefore, from the perspective of reliability, it is better to suspend conventional torsion rods. This kind of suspension is a metal torsion rod that provides buffering through the torsion effect of metal. Such tank suspension has been going on since World War II.
It has been used until now, and it is still used on tanks in many countries.
Qin Zhenhua nodded: "At present, we should pursue high technology, and we should not pursue high technology, so we should give up. In terms of suspension, we should use a torsion rod to hang it."
As the most mature suspension, the torsion bar suspension can hardly find any disadvantages. Now, with the gradual maturity of technology, the weight of the torsion bar can be further reduced. For light tanks, this should be the most suitable choice.
It's right.
Of course, one of the characteristics of torsion rod suspension is that the left and right asymmetry is the same structure as the two torsion rods, one forward and the other backward, so that the twisting of the center torsion rod can be used to absorb shock.
Therefore, for tanks suspended by torsion rods, the load bearing wheels on the left and right sides are not on a horizontal line, and the distance between the load bearing wheels can be half apart from the front and rear.
All the details have been decided, and this new light tank prototype was quickly designed. The current tank designers have been able to put down the drawing board and use computers to design it.
The designed things can be presented directly on the computer.
When he saw the first draft of the design, Qin Zhenhua shook his head helplessly. The appearance of the tank looked so familiar, it looked like a 99 tank of the smallest number! From the front armor, to the body of the vehicle, and to the turret,
It looks like it is almost as molded as the 99 tank.
"At present, we think that the design plan of our own 99 tank is the most mature, so of course we have to take out the most mature plan. Of course, the design drawing you see is carrying additional
If there is no additional armor, then this tank is very similar to the original version of the Type 99 tank. There is tilted armor in front of the turret." Seeing Qin Zhenhua's emotion, the designer next to him introduced.
Qin Zhenhua nodded. He recognized this sentence. The design plan of his 99 tank should be the most mature. He did not deliberately pursue tallness like Western tanks, nor did he deliberately pursue reduced frontal bulletproof like Soviet tanks.
The area, the solution they adopted, the medium body and the small turret, is a combination of Chinese and Western styles, and the small plug-like gun shield design is even more full of oriental design concepts.
Since you already have a mature 99 tank design plan, it is naturally the most suitable to use it. There is no need to innovate any more, just use your own design plan.
"We have modified all the exposed problems in the design stage through computer design, especially the assembly process, which has also been simulated, greatly reducing the probability of failure." Speaking of this design, the design
