"2oo tons?" Lang Xuan exclaimed, she really couldn't imagine how huge a car with a load of 2oo tons could be.

"It's just carrying muck and the like, if it's ore, it can weigh more than 3oo tons," Andrei's tone became more and more proud, "When we were making this kind of large mining vehicle in Belas, there were no large mining vehicles of the same type in the world. ”

"So powerful?!" Lin Zheng was also suppressed, carrying more than 3oo tons of ore? Nima, isn't this a train at all?

"That's not all," the old man became more proud, "our cars are not only loaded more than others, but also have lower fuel consumption, and our Soviet Union can reduce fuel consumption by 3o% compared with the same type of mining vehicles." ”

USSR? No wonder it's called Andrei, a typical Slavic name, who dares to love that this guy is a native of the former Soviet Union. But...... Were the Soviets able to make fuel-efficient guys to come?

"Mr. Andrey, I admire the strength of the Soviet Union's heavy industry, but it seems that the former Soviet Union had no advantage in terms of fuel consumption of the power system, right?" Lin Zheng asked Andre very shamelessly.

"Because we use electric drives," the old man is proud of, "we use specially tuned diesel-electromechanical and large in-wheel motors installed in the wheel hubs to drive the vehicles...... Do you know anything about electric motors? ”

"I know some," Lin Zheng nodded, he still knows a little about the characteristics of the motor, although he is engaged in software, but the software is also based on hardware, and the electricity must be understood, "The power and torque output ratio of the motor is greater than that of the diesel engine, the power and torque output ratio of the diesel engine for commercial vehicles can reach a maximum of 1:6, and the power and torque output ratio of the motor can even reach 1:2o as long as it is reasonable, and the maximum torque output can be achieved at the start." Lin Zheng nodded again and again.

"That's right, we designed this car by using the high torque characteristics of the electric motor, and I am the chief designer of the electric transmission part," the old man said proudly. Perhaps he was aroused by Lin Zheng, and said to Lin Zheng proudly, "Our Minsk Tractor Heavy Industry Consortium has also designed a heavy military wheeled off-road transport vehicle that uses a gas turbine to drive the electric motor and all-electric propulsion, do you know how big that car is?" ”

"How old?" Lin Zheng couldn't help but swallow his spit, the Russians have inherited their simple and direct character, everything is bigger the better, and now listen to Andrei's boasting. Lin Zheng couldn't help but feel a little itchy in his heart.

"More than 3o meters long, more than 5 meters high and wide, with 12 axles, 24 heavy-duty military off-road tires, each tire has an independent differential control system and independent suspension, and we installed a 125o hp gas turbine to drive the motor, and 24 hub motors to drive 24 wheels. It can easily achieve on-the-spot steering, and the off-road load is more than 2oo tons. The old man looked proud, "If it is on a flat road, there is no problem with a load of 5oo tons." ”

Lin Zheng swallowed his saliva "Goodong~~": Nima! Sure enough, the crazy Russians, put a gas turbine in a car, how the hell did they come up with it? Where is this a car, is this clearly a small power station?

Lin Zheng is not very familiar with machinery. However, thanks to the blessing of the major, I know a little bit about electric transmission, and naturally know that this is a rather not simple creation, and it is not easy to control so many high-power electric motors in one car for all-electric transmission under the existing technical conditions - even today, only the next generation of military vehicles have begun to try to use similar all-electric transmission, and the product in Andrei's mouth should be a product of more than ten or twenty years ago, right?

"It's really powerful," Lin Zheng swallowed hard. "What kind of electric drive part of the military off-road vehicle was also designed by you?"

The old guy's face turned a rare red, "That's not it. ”

Huh~~ Boss Lin was a little depressed: I thought it was designed by you, but it turned out to be not after a long time.

Lin Zheng's disdain obviously stimulated the old man, Andre had a stalk in his neck, his face was red and his neck was thick and sprayed Lin Zheng's saliva, "Although I didn't design the electric system of which car, I was also responsible for part of the work......"

"That's why Terex has a crush on you?" Lin Zheng looked Andre up and down. "I'm strange, please forgive me for being direct, since Terex values your skills in electric drives for heavy-duty vehicles." Why are you just a maintenance engineer now? ”

After the collapse of the Soviet Union, a large number of former Soviet engineers and technicians were poached by enterprises in European and American countries, and it was not strange for Lin Zheng that Andre was poached by Terex, but after Terex poached Andre, he did not let him do his job, but became a maintenance engineer of the vehicle, which is very intriguing, anyway, in Lin Zheng's view, Terex's approach is "Although I don't need such a person, I will definitely not keep it for you Russia".

Lin Zheng's guess is crooked, in fact, Terex thinks so, for Terex, after digging Andrei away, Russia and Belarus will have one less expert in the electric drive of heavy vehicles, although Terex is only the "little guy" in the heavy mining vehicle, but with Andre in his own hands, not only Belarus does not have such talents, but also prevents such talents from being poached by Caterpillar, Liebherr, Hitachi Construction Machinery and Komatsu, It is equivalent to weakening their strength in disguise, which is really cost-effective.

But as the saying goes, you don't hit people in the face, and you don't expose your shortcomings when you scold people, Lin Zheng's words just poked at the most depressed place in Andrei's heart, and the old man flicked his sleeves and left angrily.

…………………………………………

"Lin Zheng, do you value this old man very much?" Looking at Lin Zheng, who was looking at Andre with a weird smile, Lang Xuan shuddered excitedly: she always felt that Lin Zheng's gaze at Andre was like an owl staring at a vole.

Lin Zheng didn't answer, but asked Lang Xuan a completely irrelevant question, "Xiao Xuan, what industry do you say will never go out of style?" ”

Xiao Xuan? Lang Xuan's heart trembled, when did he start calling me that? But looking at Lin Zheng's expression, it didn't seem like it was intentional, he hesitated, pressed the churning in his heart, and said, "It should be food, clothing, housing and transportation, right?" ”

"Yes, as long as there are people who save zài, food, clothing, housing, transportation, and industries related to these four things will never be without food...... How about we dig up Andrei? ”

"Dig Andre here?" Lang Xuan didn't expect Lin Zheng to have such an idea, and asked suspiciously, "Are you going to make cars?" ”

"No, I'm going to make motors."

"Motors?"

"That's right, it's the motor," Lin Zheng said affirmatively, "Xiaoxuan, let me ask you, in terms of power, you know the typical representatives of the three industrial revolutions, right?" ”

"Of course, we know that the first industrial revolution is represented by the steam engine, the second industrial revolution is represented by the internal combustion engine, and the third industrial revolution is represented by electric power, microelectronics technology, and nuclear energy." Anyway, he is also highly educated, and Lang Xuan naturally knows this basic common-sense thing.

"That's it, but don't you think it's strange that now that the third industrial revolution has passed for so long, some people already think that we have entered the era of the fourth industrial revolution, but why is the prime motive used in our transportation tools still from the era of the second industrial revolution? It should be normal to switch from using oil to electricity, right? ”

Well? Lin Zheng didn't say this question, Lang Xuan hadn't realized it yet, but now that he heard Lin Zheng say this, Lang Xuan really felt ...... Does it really seem to make sense?

After hesitating for a moment, Lang Xuan said, "But the internal combustion engine has only been on display for many years, so this is ...... Is there any 1oo years? How do you see that the internal combustion engine still has a lot of room for performance improvement, before the internal combustion engine is not developed to the extreme, it seems that there is no need to show electric vehicles, and the current electric motor is still relatively poor. ”

The truth sounded like this, but Lin Zheng suddenly smiled weirdly, "The electric difference is still relatively weak?" Sister Lang, you definitely don't know that around 19oo, the steam cars at that time ...... I'm talking about steam cars, not steam trains...... It can already run up to 2oo kilometers, but how fast can a car powered by an internal combustion engine run at that time? If you look at the current electric car and the internal combustion engine car, is the difference between them very similar to the situation between the steam car and the internal combustion engine car around 19oo? ”

Was a steam car 1oo years ago already so powerful? Lin Zheng's words completely subverted Lang Xuan's perception of automobiles, but she didn't know much about the history of automobiles, and she didn't know what to say for a while.

Lin Zheng didn't expect Lang Xuan to know much about cars, and continued to take care of himself, "Then do you know that energy-saving lamps have actually been clear for decades, but capitalists do not allow energy-saving lamps to appear on the market at all in order to monopolize interests?" ”

"And what's going on?" Lang Xuan frowned slightly, it seemed that he had heard of such a thing, but whether it was the case or not, Lang Xuan was not very sure.

"If you don't believe me, you can check it out." Lin Zheng swore solemnly.

In fact, Lin Zheng doesn't remember it very clearly, but the teacher mentioned it in a class when he was in college, whether there is such a thing Lin Zheng naturally didn't go to verify, but at this time, it was used to fool Lang Xuan, and the effect must be excellent.

Sure enough, Lin Zheng's words really frightened Lang Xuan, and thinking about it along this line of thought, Lang Xuan was frightened by his own guess, "What do you mean...... The electric motor that can be used in electric vehicles has actually appeared for a long time, but those capitalists deliberately cover up the electric motor suitable for car power in order to maximize profits? ”
