The power of the tank engine is often one or two thousand rpm. Even if it passes through the gearbox, the speed is still very high and cannot be directly input to the driving wheel. There will be a speed change in the middle.
From the tank during World War II, you can see that the tank's driving wheel was surprisingly large, and it was almost as big as the load-bearing wheel below. Why was it so big? Don't the designer know that it was going to design smaller?
In fact, this is because there is also a set of planetary gears in this driving wheel. Its principle is basically the same as the wheel-side reducer used by heavy trucks. The power transmitted by the transmission is still very large when the driving wheel is reached.
I have to slow down again. The driving wheel that looks quite big is because there is a set of gears inside.
Now, the driving wheel is smaller, and the reducer is placed inside the engine compartment of the tank. Now, the solution proposed by Qin Zhenhua is to directly design the reducer behind the engine, so as to change the power output direction and reduce the speed at the same time.
All done.
The speed of entering the gearbox is reduced, so the operation of the gearbox is easier.
"Yes, the plan you proposed is good." Zhu Lao said: "Now, we need to invest all our energy in accordance with this plan and strive to make this transmission by the end of this year!"
As time is delaying again, they must be in a hurry. It is not a few months before the Chinese New Year. In these few months, making the gearbox means that everyone has to pay for the continuous day and night.
efforts.
But they have no choice. They must do this. When they are bored by foreigners, they need to be successful and let foreigners see that without their skills, the Eastern power can still make what they need.
!
This is the national confidence and cohesion of the Eastern powers!
"Old Zhu, then our tank test drive now?" Zhang Xiangqian asked Mr. Zhu.
Now, the fire control system of the third generation tank has not been developed yet. Now the test run mainly verifies the tank's power system. I didn't expect that this incident came out in the middle. Now the transmission system is going to be pushed down and started over again. So, will the test run continue?
?
"The test run cannot be stopped, so continue. Even if we only test our engine, we must continue." Mr. Zhu said.
"Yes." Zhang Xiangqian replied.
Test runs are not only about testing the transmission system, but also about testing the engine, chassis, tracks, and load-bearing wheels. All aspects are important. Therefore, even if the Germans do not give their own technology, they have now installed hydraulic transmission.
The system's prototype car cannot be tested and must be carried out as soon as possible.
"If everyone wants to speed up R&D, I suggest setting up the R&D site in the transmission branch of our first machine factory." Qin Zhenhua said: "There are experienced masters there. At the same time, if CNC processing is needed, our factory will also
It is very convenient, so it may cost more while designing, manufacturing and improving it, but the progress is easy to ensure."
Mr. Zhu nodded: "Well, then that's it."
When Qin Zhenhua left the workshop, his mind was a little confused. Just now, he only considered the matter of the third generation of tanks. In addition to the transmission system, the third generation of tanks are all made in China, so it is enough to solve the problem of the transmission system.
However, many other projects of the Yimai Factory were wasted, and the most expensive one should be the Jaguar Tank.
So far, two prototype cars have been manufactured, one in the United States and one in the machine factory.
Qin Zhenhua walked towards the workshop on the other side with heavy steps. Inside, the Jaguar tank was also standing quietly.
In front of the tank, two women stood, with their backs facing Qin Zhenhua. Her short hair fluttered in the wind when Qin Zhenhua opened the door, and her figure seemed a little declining.
"Do you know too?" Qin Zhenhua looked at his wife and asked her.
One of the ones standing in front of this tank is Wang Xiaoyu. When he was co-developing the Jaguar project, Wang Xiaoyu also went to the United States. Although it was mainly aimed at the fire control system, he also devoted a lot of feelings to the tank.
, She was so calm when she was in the Soviet Union that she was trained on the Jaguar tank.
The other is Nie Qianqian. Now, the news of the suspension of cooperation between the two sides in military industry must have reached Wang Xiaoyu's ears. Perhaps it was Nie Qianqian who told her that Nie Qianqian, as a reporter, must be the most informative news. Now, the two
The man stood here, looking at the Jaguar Tank, not knowing what he was thinking, until Qin Zhenhua came in, said something, but did not turn his head to look at Qin Zhenhua, but was still standing there, looking at the Jaguar Tank.
From the appearance, the Jaguar tank has deviated from the original 59 tank. It has lengthened the body, mounted on the pulley and side skirts, which looks very modern, and the turret is full of modernity.
It's like a small M1 tank.
"This tank originally had no future." After a long time, Wang Xiaoyu finally said something.

"There is no future?" Qin Zhenhua quickly realized as he listened to Wang Xiaoyu's words: "Yes, in the later stage of development, it has completely deviated from the previous idea. Even without this incident, this kind of jaguar tank will not be sold.
Go out.”
Although the suit is added, it looks very intimidating and has a beautiful appearance, and the rear is replaced with a 750-horsepower diesel engine and a four-speed automatic transmission, this has also led to its continuous increase in price.
Originally, it was planned that this kind of tank was sold for one million yuan, but the cost had soared to one and a half million yuan. The products of the Eastern powers were of good quality and low price, but Western accessories were too expensive.
In this way, who would buy such a tank? The price is about two million, which is comparable to the tank of the T-72. You know, in the eyes of many people, the T-72 is all
A true third-generation tank.
There is no future, so even if this project is gone now, there is no regret.
"We have learned a lot of experience from this project. Although the tuition fee is a bit too expensive, we have learned a lot of things after all." Wang Xiaoyu said: "For example, in the future, the first machine factory wants to change the 59 tank, and finally, the final result is
It can also be changed to this way, but the price of using our own parts will be greatly reduced. Therefore, if we do it ourselves, there is a market for it."
