"There are big problems with this design!" In the Yimai Factory, a group of people were sitting in the conference room, studying the drawings one by one.
How many drawings are there for a tank? How many train sheaths are needed to be installed. If this is the case, the machine factory will indeed not be able to obtain so many drawings.
What you have now obtained is just the overall design drawings of the 321 chassis. These design drawings can be loaded in a large box. The second machine factory has put in some effort and got these from the Ice City Factory.
Now, Xie Huimin and others from the Second Machinery Factory are also studying and pondering together here.
"What's the problem?" After all, it was a cannon manufacturer and was not very clear about manufacturing the whole vehicle. Therefore, Xie Huimin asked now, which was quite surprised.
The layman watches the fun, and the expert sees the tricks. They just take a look and know if there is any problem.
"First of all, the engine's heat dissipation is a big problem." Wu Ruihua said.
The first machine factory mainly builds tanks. The tank engines are deployed at the back. Because they are at the back, the armor does not need to be too thick. In this way, the top cover will be opened and the engine will be disassembled and assembled, and it will not waste any effort.
At the same time, the heat in the tank engine is very high, so this part of the heat must be dissipated. Therefore, tank engines often place the heat dissipation water tank on the top of the tank, and then open a heat dissipation hole in the top armor behind the tank
This is how the current 1224 tank has been specially developed. Two circular radiators have been opened on the top of the tank, which looks like two big eyes.
This also becomes the weakest place for tanks. Even if the least RPG-2 is hit here, it can break the cooling window and then break the tank engine, so that the tank will not move!
However, since it is at the back, there is no big problem. When fighting in cities, infantry protection can be deployed behind them, which makes the tank safer.
And what about the 321 chassis in front of you?
This kind of chassis requires a front engine. The same 12150L tank engine is placed on the right side of the vehicle body. The remaining space on the left becomes the cockpit, and in the front, it is all blocked.
, there is the position of the transmission shaft.
When the engine is deployed in front, heat dissipation becomes a big problem!
Everyone knows how high the heat of this kind of engine is. Now, the way Ice City Factory does is to directly install an engine cover and plug the engine into it.
In this way, it may be fine to test drives in Ice City, but if you go to the south, the engine will definitely overheat. If you export it, you will not be able to start moving at all when you reach the desert area.
The driver is guarding the engine, and it will definitely be warm in winter. In summer, it tastes so good!
"This is a big problem, a design mistake. Researchers from relevant departments did not notice this problem." Qin Zhenhua said: "Let's solve it."
Xie Huimin's eyes shining on one side and asked Qin Zhenhua: "How to solve it?"
"First of all, it must have a heat dissipation grille." Qin Zhenhua said: "We will drive this heat dissipation grille above the gearbox."
The heat dissipation grille is not driven above the engine, but above the gearbox. This is incredible. Everyone showed confusion about this proposal. What are they planning to do?
Then, Qin Zhenhua continued: "First of all, this place is tilted. Only in this way can the air blow in when entering and enhance the heat dissipation effect."
Just like the car's radiator, deployed at the front of the car, it is to let more wind blow in after starting. Now, the inclined area in front of the car body is deployed with a gearbox, so naturally it must be on it.
The grille is opened.
"Secondly, our gearbox can add an extra layer of armor protection. From the outside, it is a weak grille. In fact, inside, the protection is stronger, so that it can have the same protection as other parts
It's even stronger."
Qin Zhenhua introduced this.
If the cooling window is opened above the engine, there is no way to add extra armor and cannot block the engine's heat dissipation. Now, opening the cooling window on the transmission is a pioneering move! This will not be less powerful.
The engine has many weak points and it will break down as soon as it hits, but the gearbox is different. The outer shell of the gearbox is made of cast steel, and with an additional layer of protection, for an armored vehicle, as long as it can be protected.
Just shoot machine gun bullets, it is absolutely fine.
"Finally, we're here, adding an extra cooling fan." Qin Zhenhua pointed to the edge and said: "From here, enter the air, and then use a high-power fan to slam into our engine compartment, so that you can
Enhanced heat dissipation! Yes, it’s just right to open the gearbox and connect an output shaft!”
Generally speaking, the engine is under the cooling window, so if the enemy sees it, they will definitely aim here to hit it. However, this place is actually not an engine at all, it is just a gearbox!
There is a partition between the gearbox and the engine, and the gearbox has added armor protection. As for the engine's heat dissipation, it is carried out through forced cooling!
This is what an experienced engineer can always think of simple and effective solutions to solve problems. Many times, it is a different approach, but it can achieve satisfactory results. The solutions he mentioned take care of both protection and heat dissipation.
Say, it's absolutely fine!
"There are also problems with the design of the load-bearing wheel." After saying this, Wang Erzhu raised a new question: "The body of this type of bicycle chassis is relatively long and uses medium-diameter load-bearing wheels, so
Its load-bearing wheel is pulled apart, but in order to take care of the weight distribution, the load-bearing wheel is mainly concentrated in the middle, with the two load-bearing wheels in the front and rear, with a relatively long distance. In this case, only torsion rod suspension is probably not strong enough."
Wang Erzhu has now started running both ends. The engine test of the coal province diesel engine factory must be participated in, and the construction of the automobile branch here must also be participated in, and he is very busy. However, Wang Erzhu, who is full of energy, works harder.
.And, the ability to be independent has gradually been demonstrated.
Hearing this, Xie Huimin's eyes widened. The people from Yimai Factory were simply amazing. They could infer so many problems based on the design alone!
When I was taking the drawings, Ice City Factory also talked about the recent problems encountered in the test run, which included the suspension problem of the deadly load-bearing wheel. Two torsion rods have been broken, and it is not possible to strengthen them even if they are specially strengthened.
!
They discovered it in the experiment, and the Yimai Factory can infer possible problems based on the drawings just based on the drawings. This is an expert!
