The first thousand four hundred and thirty-six chapters match the problem
"For an automatic transmission, four gears are enough." When Wu Ruihua and others were looking at the engine, some people were looking at the transmission.
It has become a trend for tanks to use automatic transmissions. It can free tank drivers from the complicated operations and focus more on controlling the environment. In addition to not changing gears or stepping on clutch
In addition, for the driving of the tank, it also means that the steering wheel can be operated.
Of course, it is not necessarily an automatic transmission that supports steering wheel operation, but mechanical transmissions on both sides are definitely not good. Only the hydraulic transmission system has this capability. Generally speaking, the hydraulic transmission system is combined with automatic
Transmission.
In front of the automatic transmission is a torque converter, which is also one of the cores of the transmission.
Ordinary machinery is hard connection, but the torque converter is not. Its middle is transmitted through the flowing hydraulic oil. Inevitably, this method will cause power loss, but at the same time, it will also
It can play a role in changing torque. For tanks, it has more significance and can make the tank start more easily. The speed ratio of the head gear does not need to be particularly large. The torque converter can help change torque.
There is sufficient starting torque, so there is no need for too much gear.
As for the fuel consumed, do you still care about how much fuel burned for a tank? All the military vehicles in the army are made of oil tigers, not to mention military vehicles, even civilian off-road vehicles, not to mention any of them.
It's fuel-efficient.
"Yes, after too many gears, matching will become a problem." Wang Erzhu said on the side.
More and more people gathered, and Wang Erzhu also came over and started chatting with Qin Zhenhua.
The automatic transmission does not require people to control the shifting gears. What is needed is that the computer switches the gears when needed, so there will be a new problem.
When exactly do you switch gears?
Computers can monitor various speeds, but this information alone is far from enough. Mercedes-Benz in this era has begun to use automatic transmissions on heavy trucks, but it is still not smart enough. This is not smart, but it cannot fully understand the driver.
Intent.
For example, if you step on the accelerator slowly, you can upgrade the gears smoothly, keep increasing the speed, and step on the accelerator violently, you must lower the gears to quickly complete the speed up, but this alone cannot do it.
For example, when you encounter an uphill in front, the driver stepped on the accelerator and originally wanted to gain sufficient traction. As a result, the computer determined that it needed to accelerate, so it started to upgrade. After the uphill, the traction was insufficient and the car could not climb.
Go up, so you start to lower the gear. After lowering, the car speeds up and then start to increase the gear. In this way, the gears will be switched back and forth, and you don’t know what to do. This is an unsmart gearbox.
This is even more true for tanks. If you switch gears back and forth during the mountain climbing process, it won’t take long to go, and the tank will probably stop there. At this time, there will be problems with the tank.
The exercise progress will be delayed during exercises, let alone war.
"Yes, it's time for us to set up a special team to study this matching issue." Qin Zhenhua said.
Matching is not simple. What is required is the accumulation of a large amount of data, and the transmission computer will be summarized and summarized, so that you will gradually become smarter.
It is indeed planned to purchase a full set of technology from Germany, but the Germans may only give technical results. How to do the intermediate process of matching? The Germans will not teach them step by step. If you want to improve in the future, then
I have to do it myself.
This requires a lot of research. In addition to German gearboxes, there are other gearboxes.
"We have a lot of things on hand now." Qin Zhenhua said: "We already have two engines, and we need a third one. We have two transmission systems and we will have a third one. We will also have these systems.
Cross-match is required. Through repeated research, we can determine the best solution.”
In this process, technicians from major Eastern powers can also exercise their technical strength.
"Yes, you must find the best solution from it." Groz said.
What is the matter of the Eastern Powers? It is their business. In short, what Lao Ba wants is the best solution. If the Eastern Powers want to cross-matches, it is naturally better. If the British engine is equipped with a German gearbox, it is better to use it.
What about? This German gearbox must be produced in major Eastern countries, which can minimize costs.
"We have to find an experienced master to lead the team." Qin Zhenhua's mind went around a few times, and among the technicians of the First Machine Factory, he was searching for names one by one. Suddenly, he thought of something:
"Call Master Zhang Xiangqian over."
What is the most important thing about this match? Of course, it is an experienced test runner! The test runners drive tanks all year round. Under what circumstances and what gears the tanks are switching, they are the best at this matching task. Therefore, the task of this matching is given to an excellent one.
The test runner is the best.
Of course, this is not just a test driver, but also an excellent technician. Zhang Xiangqian's skills are also quite exquisite. He followed him abroad many times and had a broad vision. He has been working hard to learn knowledge.
Now that computer operation is no problem, you can use computers to analyze proficiently. Now, isn’t it the best choice to let it match?
What is Zhang Xiangqian doing? Of course, he is working as a test runner for the third generation tank. These days, he has been stuck on the third generation tank almost every day. He is already old and it is not a big deal to be bumpy all day long. It is better to give him a research task.
Hearing Qin Zhenhua's greeting, Wang Erzhu also guessed his thoughts and nodded and said, "Uncle Zhang is the best place to take on the main points. If we want to copy our gearbox, we have to start with hardware and software."
Someone went to greet him soon, but after waiting for a long time, he couldn't see Zhang Xiangqian coming. Qin Zhenhua was a little surprised. Could it be that Zhang Xiangqian was so happy to run in the test yard and didn't want to come back?
Finally, the person who went to call came back, but his face was not very good at this time: "Director Qin, Mr. Zhu, please come over."
"Old Zhu?" Qin Zhenhua felt something was wrong.
This tank engine and gearbox from the UK also represent the highest level in the UK. In theory, Mr. Zhu should have come to see it. Since the third generation of tanks were launched, Mr. Zhu has often stayed in the first machine factory. But he
But he didn't come. Now, he actually wants to invite him to come here?
Could it be that something big has happened to the test drive?
