"Passenger cars and trucks carry much heavier loads than cars. Without strong power, it will be very difficult to go uphill. Similarly, when going downhill, if the braking system does not work, it is easy to have a serious accident."
"What does this braking system look like?"
Liu Jin nodded with satisfaction and asked about the braking system again.
The braking system of passenger cars and trucks is undoubtedly the most important thing. If the brakes are not good, serious accidents will easily occur, and many people will die if the brakes are not good.
"Liu Gong, we have spent a long time thinking and researching on the braking system. The braking method on bicycles is obviously not suitable for use on cars."
"So we studied the hydraulic brake system, which uses the principle that liquid cannot be compressed and can transmit 100% of the energy. By stepping on the brake pedal, the brake oil transmits pressure, and then drives the brake pump to perform braking."
"The working principle of the brake pump is to create a large amount of frictional heat energy and dissipate the kinetic energy through friction and heat energy."
When Lu Qing heard this, he quickly explained it to Liu Jin in detail.
When Liu Jin heard this, he immediately felt that he didn't understand it. After carefully combining some of the knowledge he had learned in later generations, he discovered that Ming's technology and technology development had indeed reached a certain stage.
It's kinetic energy, thermal energy, friction, etc. Obviously, these basic things have been clarified and studied clearly, so we can continue to make rapid progress.
If you don't even understand these basic things, don't expect that science and technology will advance by leaps and bounds. This makes it necessary to mention the importance of Liu Jin's efforts to popularize basic education.
The new school, founded with reference to the educational methods of later generations, is definitely successful in terms of basic education. Although there is nothing too advanced or theoretical, once the foundation is established, the subsequent development will be very rapid.
This may be the reason why Ming Dynasty was able to build all the cars in just a dozen years. In the final analysis, it was due to basic education.
Without basic education, Ming Dynasty would not have been able to continuously emerge with various emerging technologies and scientific and technological talents, and technological development would not have been so rapid.
"Not bad, not bad~"
Liu Jin also nodded repeatedly. The braking principles and technologies of later generations of cars were also like this. Of course, large trucks and trucks generally use air brakes, and the technical content is even higher. It is estimated that it will not be researched for a while.
“This bus is pretty good!”
"Build dozens of them first, and then use them to travel between Beijing and Tianjin, so that more people can try the experience of riding a car."
Liu Jin quickly thought of a good deal.
Long-distance bus transportation has a very glorious history in later generations.
At the beginning of reform and opening up, before cars became popular, long-distance buses were the main way for people to travel. At that time, traveling far away was not an easy task.
The long-distance bus station is also very impressive. Things like compulsory consumption are banned frequently. Everyone is bullish. The income of a long-distance driver is also quite high. The salary for driving is only a fraction, and most of it is kickbacks.
It was not until the 21st century that cars began to enter thousands of households, more highways were built, and high-speed rail became more popular, so long-distance buses gradually declined.
Judging from the current situation in Ming Dynasty, setting up a long-distance bus company will definitely have great potential. At least, there will definitely be no problem in making money.
It is absolutely difficult for cars to enter people's homes in a short period of time, and it is impossible to build trains everywhere. Especially when the railway construction in the Ming Dynasty is basically privately funded, it will focus on economic benefits.
No one will pay to repair lines that are ineffective.
Cars have naturally become the most important means of travel.
Of course, horses and carriages are what people travel most in the Ming Dynasty now, but horses and carriages also have their limitations.
"Yes, Mr. Liu~"
When Lu Qing heard this, he quickly replied.
"You can tell Duan Hai later that we should also pay attention to the production of this kind of passenger cars. I believe that the sales volume of passenger cars may not be worse than that of cars, because passenger cars can be invested and used to make money."
Liu Jin thought for a moment and then continued to give instructions: "We can set up a separate factory to manufacture passenger cars. How is the research on heavy-duty trucks going?"
"Mr. Liu, we are in the process of researching trucks. Because trucks have to carry heavy loads, the biggest problem is power. We are currently studying more powerful internal combustion engines to support trucks."
Lu Qing also replied quickly.
"Well, you guys should be busy and study slowly. Building a car is a very profound knowledge. There are many areas that need to be studied. There is still a long way to go before we can build a good car."
Liu Jin nodded with satisfaction, and then prepared to go see Zhang Mao.
Here at the Mercedes-Benz car production plant, Zhang Mao looked at the Mercedes-Benz car production line in front of him with his eyes straight. In his eyes, where is the production line in front of him? This is a big gold mine.
Walking from one end of the workshop to the other, a car is assembled from parts one by one. A pile of iron lumps and other things are assembled together to become a Mercedes-Benz car that can be sold for more than 6,000 taels of silver.
Is there any better way to make money than this?
What is this if not a gold mine?
In Zhang Mao's opinion, this car is not difficult. An engine, four wheels, some iron frames and the like, just a few things, can be sold for more than 6,000 taels of silver. It is simply incredible.
"It's too dark, it's too dark~"
While watching, Zhang Mao just shook his head and lamented that Liu Jin was really evil-hearted.
Just a few things like this put together sold for more than 6,000 taels of silver. It was so popular that it cost grandma's house.
At the same time, it also strengthened Zhang Mao's determination to build cars.
Since Liu Jin can make a lot of money through this, why can't he himself?
It's not a difficult thing. Is the internal combustion engine difficult?
Or is it difficult to make wheels, or is it difficult to put them together?
In Zhang Mao's opinion, it is much easier to build a car, this business can be profitable, and this big business must not be missed.
"Mr. Zhang~"
Liu Jin walked over and couldn't help but smile when he saw Zhang Mao's shining little eyes.
Zhang Mao has always been like this, he can't take his eyes away when he sees the benefits.
However, if you think that building a car is easy, you are wrong. Building a car is a real technical job, and you will know it later.
"You brat, can you give me some technicians?"
Seeing Liu Jin, Zhang Mao rolled his eyes and said with a smile.
"This won't work, it won't work~"
"There is no need to discuss it. This is a cash cow that I have worked hard to cultivate and make money for me. No matter what I say, it will not work."
When Liu Jin heard this, he immediately shook his head.
It’s a beautiful thing to think about. The talents I have worked so hard to cultivate will leave as soon as you open your mouth. Are you better at making money, or do you understand talents better?
"What's yours and what's mine, do we still share it with each other?"
"No big deal, I'll just tell you how many concubines there are."
Of course Zhang Mao would not give up like this and said quickly.
"If I want to take a concubine, I can do it at any time. You can tell me where I need it."
"No, no, no matter what you say, it won't do."
Liu Jin shook his head repeatedly, saying this matter was not discussed.
"Smelly boy, stinky boy, let me tell you a few more wives. They are ladies from famous families. I guarantee you will like them."
"Mr. Zhang, there is no need to discuss this matter."
Returning to his home, Liu Jin called over several stewards who specialized in helping him manage his properties.
"The Mercedes-Benz automobile factory has developed something called a passenger car. This kind of passenger car is specially used to carry people. It can carry dozens of people at a time."
"I plan to set up a Daming long-distance bus company to use this kind of buses to carry out long-distance passenger transportation between cities to facilitate travel between various places."
"The first line to be built is the line between Tianjin and Beijing. Find a prosperous place with a large flow of people in Beijing and Tianjin and build a passenger station first. The passenger station is specially used to sell tickets for passengers taking buses.
Used for getting on and off the bus.”
Liu Jin began to explain the operation methods of later long-distance bus stations and ordered his men to build the Ming Dynasty long-distance bus station.
Passenger cars are out, so naturally they can’t be seen anywhere. Of course, they have to be used. Making money is not the main purpose. The most important thing is to let more people understand the cars and feel the convenience and convenience of the cars.
