In later generations, when it comes to electric vehicles, it is high-end, new energy. In fact, when cars first appeared, the power system had steam engines, internal combustion engines, and batteries to drive the electric motor. This is an electric vehicle, only
However, it was eventually eliminated, and only the internal combustion engine developed.
As for tanks, in the early days of their appearance, there were also many technological controversies. As early as the tanks appeared, electric tanks also appeared. The first was the French "Saint Samon" tank developed in 1917. This tank uses a gasoline engine.
Drive the DC generator, then drive the left and right DC motors to drive the track to rotate.
Moreover, this is not a test vehicle, and about 400 vehicles were produced after finalization.
At the end of World War I, the French developed another 2C heavy tank with electric transmission, which weighed 70 tons. However, before it was put into production, the war ended.
Why did electric-driven tanks start to appear at the beginning? Of course, this is because of the transmission system problem.
Driving a tank is more complicated than driving a car. It not only requires a clutch, but also needs to shift gears. At the same time, when steering, it also needs to change the speed difference of the tracks on both sides. Therefore, it is quite difficult, and the difficulty of mechanical transmission is too great.
If it is replaced with an electric motor, it will be much easier. How fast the motor speed is? Adjustment is much more convenient than adjustment of the clutch and gearbox.
During World War II, there were more tanks with electric transmission systems. At that time, the famous German tiger tanks were designed with electric transmission solutions. But in the end they did not put them into actual combat? However, the 188-ton mouse tank was
At that time, the electric transmission system was finally adopted. At the same time, during this period, the United Kingdom and the United States had models of electric transmission tanks?
The UK trial-produced heavy tank with TOG electric transmission. The US trial-produced T1E1 heavy tank and T23 medium tank? Both use General Electric's electric transmission devices.
It can be said that in the era at that time, the electric transmission system had gradually become practical.
However? After the end of World War II? With the advancement of technology, the tank's transmission system began to take the conventional route. After all, electric transmission sounds good, but there is one big problem? It is the energy loss problem? Use a gasoline engine to directly
Drive a tank? And first use a gasoline engine to generate electricity, and then use electric to drive the tank. The latter has gone through a secondary conversion process? The efficiency of this conversion is not high. (Recalling the recent video I watched, someone has begun to promote electric cars without charging,
Unlimited battery life, the method is very simple. On an electric car, just bring a gasoline generator to charge the electric car. As long as you keep refueling, you can have unlimited battery life. This is simply a fart and take off your pants. If you burn oil, what are you doing
If you don’t drive a motorcycle directly, is it because you don’t have motorcycles?)
Later, tanks began to take the conventional route, but this did not mean that the tank's electric transmission system was abandoned. R&D work was constantly being done. For example, in 1960, the American Armored Vehicle Transportation and Manufacturing Company (FMC).
The company, a company that cooperates with the first machine factory, began to replace the transmission device of the M113 vehicle with an electric transmission system, and the generator has been replaced with an alternator, which is supplied to the DC motor through a silicon rectifier.

Europeans are also doing it. In 1986, Germany installed a permanent magnet motor electric drive system on the "Weasel" infantry fighting vehicle. These systems can improve performance and reduce the loss of intermediate transmission.
All technologies are under pre-research and are not really used in existing equipment, but we can also see that electric transmission still has prospects for use, especially in the current conference, which discusses future tank technology.
.
What kind of transmission system is needed to withstand powerful power output with two thousand horsepower? It is naturally the best to convert it into electric transmission! Especially, at present, this is already used in large mining vehicles.
There is a technical route, and those vehicles with a load capacity of hundreds of tons, even internal diesel locomotives, are driven by electricity.
"The gas turbine has a small size and the highest thermal efficiency, but the fuel consumption is also high. Therefore, if an electric transmission system is used in the future, using the gas turbine to drive the generator should save more volume than a diesel engine to drive the generator." Qin Zhenhua said: "We believe that
The future dynamic form is likely to adopt this technological route.”
Gas turbines are still useful, and there will be opportunities in the future, so don’t worry, Qin Zhenhua’s words naturally mean this.
After hearing Qin Zhenhua's words, Nikola nodded. The other party did not deny the gas turbine, and also said that it was a future trend. After this meeting, the final conclusion must be that the gas turbine is the power of the future tank!
In this way, they can continue to study. After all, the prospects for gas turbine tanks have been somewhat bad in recent years, and they are also anxious.
"So, why do you have to use electric transmission?" Nikolai said, "At the time when the tank power was only five or six hundred horsepower, I felt that the normal transmission system could not bear it and electric transmission was necessary. What happened? The tank power is now
It has reached 1,500 horsepower, and the conventional transmission system is still used, which is strengthened to 2,000 horsepower. It can also be used. We should not ignore the potential of the existing technology and continue to dig deeper. It is no problem.
of."
This is not because he is embarrassed by the people in the Kirov factory, but he is just a little curious. If the transmission system is continued to be strengthened, it should be fine.
"Yes, of course we can do this, so we use electric transmission to simplify our transmission system, which is just one of the benefits. Another more important thing is that it can provide a powerful power supply to the tank and give the tank a deeper
Modification potential, for example, our tank guns are still cannons with normal chemical energy. In the future, they may be electromagnetic guns or laser guns. In short, these require powerful electrical energy as energy."
For ordinary tanks, the electricity is provided by a small generator driven by an engine. The electricity is not strong enough and only meets ordinary needs. If weapons are used, the power supply required will increase by thousands of times.
, Only by using all the power to generate electricity is enough.
"Laser tank? You are too imaginative, how is this possible?" Suddenly, someone sneered.
"Is there really no laser tank in this world?" Qin Zhenhua asked back.
As soon as these words were said, many people frowned.
