The torque converter is a key component of the automatic transmission. The power of the engine can be amplified after passing through this device. Of course, the function is also very simple. There is a set of blades in front, which are connected to the engine.
When the engine rotates, it will drive the blade. Then, the blade will stir up the hydraulic oil inside and flow forward to impact the front impeller, and drive the front and rear impeller to rotate. The front and rear rotation speeds are different. In this way,
It plays a role in reducing the speed and increasing the torque, and this allows the engine's power to be softly connected. Therefore, no matter what problems are encountered in the rear, the front engine will not be affected too much. In this way, the car starts and changes gear position
, all very easy.
However, during operation, this torque converter will also heat up. If it is a car, using this structure will not have much problem. However, for trucks, the torque converter
The heat in the appliance is too high, so a special radiator is needed to transfer this heat out.
The most obvious one is a large-piece car. The so-called large-piece car is a vehicle when transporting special large items. For example, the parts of some machines often weigh hundreds of tons. Ordinary vehicles cannot transport them, so they can only
Transported through such large-piece trucks. Some goods are expensive and cannot bear too much bumps. Therefore, at this time, special large-piece trucks have to be used. This kind of vehicle can often have more than 500 horsepower.
The power and transmission system are also relatively complete, and this torque converter is also an essential component.
Now, this heavy military vehicle actually uses this device. Everyone present is curious, but Xiang Dahai thought of something and said: "Why don't you use AMT gearbox? Is it because of this gearbox?
Is it flawed and can't meet the needs of military vehicles at all?"
They already know that the FAW-based bidding vehicle uses an automatic transmission, but it is not an advanced transmission with a torque converter, but simply adding a set of automatic replacement to the manual transmission
The gear component forms this automatic transmission. This transmission does not have a torque converter and uses an ordinary clutch. This method must have defects. Now, I just take this problem out and explain it.
Problems with FAW's vehicles.
This sentence is sophisticated. If Qin Zhenhua said that the AMT transmission is good, why don’t they use this car now? If it is not good, it means that there is something wrong with the FAW factory’s products. No matter what,
All can hurt one of them.
At this time, Qin Zhenhua just smiled: "Brother Dahai, any machine component has its own scope of application. You can't say whether something is good or not, you can only say whether something is suitable or not, you
After so many years of equipment, you won’t even not understand this simple truth, right?”
Xiang Dahai was stunned. Qin Zhenhua did not jump into his trap, but began to criticize him. Even if Qin Zhenhua was the director of the Yi Machinery Factory, giving him a few words like this, he would instantly turn red and want to be thick-necked.
Arguing, but at this time, Qin Zhenhua ignored him and continued: "Your Warrior car, at the beginning, used an aluminum alloy body, and later it was replaced with steel products. You said it was aluminum
Is it better for alloys or steel?"
Qin Zhenhua's move is even more amazing. Just take their Warrior Car as an example.
The Hummer car is a copy of the Hummer car, and the Hummer car uses an aluminum alloy body, which can reduce weight. After all, although this thing only has four wheels, it has two or three tons of weight, so the body is used Aluminum alloy is also an effective way to reduce self-weight. However, after the Second Automobile Factory initially tried the aluminum alloy body, it replaced the steel body. This is because the steel is simpler and costly. Low, and metal fatigue is longer than aluminum alloy. However, good things are obvious, and they must be better than aluminum alloys. However, he cannot say that now, otherwise their Second Automobile Factory will be suspected of cutting corners. .
So, when Qin Zhenhua's question came out, Xiang Dahai suddenly felt that he seemed to have nothing to say, he couldn't say good or bad. In an instant, he was very embarrassed.
Qin Zhenhua smiled and made the other party stop talking. Qin Zhenhua continued: "So, there is no good or bad, only suitable or not, medium-sized high-mobility universal tactical vehicle, which is a ten-ton class, using an AMT gearbox. , it can meet the needs, this method can also reduce the weight of the gearbox, reduce the complexity of the structure, and save costs. It is a relatively suitable solution. However, if it is used on our heavy truck, it will not be too much. It's appropriate. This kind of gearbox will overheat the friction plate when repeatedly combining power. Therefore, we need a torque converter. This is because heavy vehicles need to transmit more power. In our car , it uses an engine with nearly 600 horsepower, and the torque reaches 2,600 Nm. If you use an ordinary gearbox, there will be no problems on the road and the clutch may burn off the off-road."
As soon as Qin Zhenhua said this, Xiang Dahai knew that he was fooled again. He was looking for topics for Qin Zhenhua. If he didn't ask, Qin Zhenhua wouldn't be able to say much without asking. Now, people not only talk about the advanced nature of the gearbox, but also the engine.
The engine with nearly 600 horsepower, what is the power level? You know, a few years ago, the tank had only more than 500 horsepower, and the cars running on the road were only 100 horsepower. Now, this kind of truck actually It is also equipped with an engine with nearly 600 horsepower!
"No, the American M977 is only 450 horsepower. Can our car use such a large horsepower?" someone asked.
If you want to talk about heavy military vehicles, you must not mention the M977. This thing is definitely the benchmark among heavy military vehicles. If each factory wants to bid for the military's heavy vehicle project, it will definitely borrow the M977 from this kind of car. , the Detroit diesel 8v92ta V-8 two-stroke diesel engine is used, with a power of 447 horsepower, which is about 450 horsepower. The first machine factory actually installed the 600 horsepower diesel engine? Needless to mention this engine How did it come about? Just to ask for demand, did you use such a large engine?
"Yes, if you were on the plain, you would definitely not be able to use such a lot of power. However, if you want to go to the plateau, you will not be able to lack motivation." Qin Zhenhua said.
Even the medium-sized ones use more than 300 horsepower engines, and the power of this heavy ones has to double.
