Domestic tanks are inherited from the T-54A line, especially the most classic three-plate and three-pole, including the second-level planetary steering machine, which are all rewarded by Stalin. For a long time from now on, the structure and relative position of these operating parts will be
No domestic designers dare to move around.
This is a classic!
Until the 69 tank, for the sake of foreign trade, hydraulic assist was added to reduce the operator's strength.
Now, for the needs of foreign trade, we have been improving and keeping pace with the world, and we have already had a way to operate the steering wheel.
The steering wheel is definitely not simply installed with a steering wheel. The steering wheel is controlled by two tracks with different speeds. The three plates and three rods are operated by mechanical means, and the steering wheel must have
A special hydraulic transmission gearbox can be used to perform it through hydraulic control, which is an upgrade to the entire transmission system. In China, it has always been at a disadvantage in this regard.
The previous three-liquid sample truck was not processed. Now, the first machine factory has introduced Western CNC machine tools to improve the processing accuracy by a higher level and have advanced processing methods. Over the years, it has also been studied.
Many Western gearboxes, such as the Sherman tanks, have accumulated rich experience.
It is no longer difficult to use the steering wheel to control it. As for whether the troops choose or not, it depends on the troops' own wishes. After all, the troops are very conservative.
These are understandable, but what does it matter if the location of the tank cab is?
Tanks with normal layout are generally the same, with the cab in front, the combat compartment in the middle, and the engine behind them.
The cab in front has always been deployed on the left in China.
This is based on the basic rules of driving on the right. The cab is on the left, which makes it easier for the tank crew to get on and off the vehicle. It inherited from the T-54A and has been 69, 79, 80. Now all tanks are designed on the left.
Yes, however, the Soviets made improvements, and the cockpit was installed in the middle from the T-64 tank.
Now, Mr. Zhu has shifted the topic to this aspect, and at this moment, when he heard his question, Fang Xian continued to shake his head helplessly. When the 123 project was about to be decided, he only felt a heavy burden on him.
, The responsibility is heavy!
"Old Zhu, you are testing me." Fang Xian said: "The benefits and disadvantages are clear at a glance."
Tanks are not used to move forward on normal roads, so they don’t have to follow the rules of driving on the left or driving on the right. As for deploying on the left, it is just a convention. Starting from the T-34, they are deployed on the left.
The Germans were also deployed on the left, and the situation was that the driver was on the left and the radio and machine gunner on the right! There was a forward machine gun on the body of the tank. At that time, the inter-car was going to be carried out.
Communication between the two must be done by a dedicated radio.
Now, since Mr. Zhu asked, Fang Xian could only answer: "However, the cab is on the left and there are serious defects. This is the driver's vision problem. The blind spot on the right will be larger, especially
After closing the cockpit, the blind spot on the right is very large."
After saying that, Fang Xian paused and said in the most professional terms: "According to our requirements, when the driver uses a periscope to observe the battlefield terrain, the vertical field of view angle is no less than 20 degrees, and the distance that cannot be observed is also
That is, to observe the dead world, you should not run 8 meters, and the horizontal field of view should ensure that there are two track widths."
"Under this requirement, it is obviously better to arrange it in the center than to arrange it on the left, so if we start the 123 project, this must be retained." Fang Xian continued: "In addition, we also have to do so.
There are other benefits, such as after entering the battlefield, once the tracks press on the anti-tank mine, the central cockpit has the greatest chance of survival."
If you press the left, the tank hand is next to you, and you will probably be shocked. If it is in the center, it will be better.
"However, the cab is in the middle, which will also bring a defect." Fang Xian continued: "That is, it is inconvenient for the driver to enter and exit."
In fact, this is the most criticized thing about the middle cab. In the middle, there is a gun barrel above the head! The driver has to practice yoga and his figure is soft enough to get in through the middle!
Otherwise, you need to turn the barrel aside when getting on and off the vehicle to facilitate entry and exit. In fact, most tanks do this.
When the tank driver exposed his head to drive, he could also see a very obvious scene. The tank driver's head was almost opposite the base of the gun barrel. If the turret rotates, it might be possible to click the driver's.
Squeeze your head out!
Especially, the large turrets in the West are rectangular. When they turn around, the diagonal length can definitely squeeze out the driver's head.
"Report, discover the target."
"Quick, turn around!"
Snap! The driver's head is gone!
Such a scene is conceivable. Of course, it is actually difficult to appear. When driving normally, your head is exposed, but it is in a marching state. The turret is locked and will not move. As for the battlefield, if the driver is on the battlefield, if
If he still exposed his head, it can only mean that his head is iron enough.
Everyone discussed the specific technical issues, and they all found it a bit funny. After finishing the issue, Fang Xian said: "Old Zhu, you must have been studying the T-72 tank for a long time, right? You also said you are right.
Not interested in the third generation tank?”
Fang Xian still did not give up and wanted to dig Mr. Zhu from the first machine factory. With the title of third-generation tank, he could fool Mr. Zhu.
Unexpectedly, Mr. Zhu said another sentence, which made Fang Xian immediately become interested. It is still possible to fool Mr. Zhu over.
Zhu Lao is so interested in the layout of a cockpit. It is obvious that Zhu Lao is very interested in surveying and mapping and imitating T-72!
As an old friend for decades, Fang Xian is still very clear about Mr. Zhu.
Who knew that Mr. Zhu's next words made Fang Xian feel uncomfortable. Unexpectedly, the other party thought so!
"In fact, even if we don't need to survey and map the T-72 tanks, we can gradually improve the existing second-generation tanks to the third-generation tanks." Zhu Lao said: "What are the second-generation tanks and the third-generation tanks?
