Yesterday, my little girl had enough of driving a car.
This morning, I woke up excitedly and watched Yang Fan modify the car.
"A car is composed of four systems. They are chassis, engine, transmission, and frame. The chassis is the wheels, suspension, steel beams and other systems. The engine is the steam engine. The transmission is the gearbox, which is used to control forward and reverse, and at the same time control the speed.
Carry out gear position control and install a braking system at the same time." Yang Fan drew the graphics of these parts on the blackboard.
In his Houhai mansion, Yang Fan set up a huge tent in the open space in the backyard to serve as a temporary car improvement workshop.
There were a lot of small stools placed below. Xiao Niangpi, Lin Yueru, Yao Guang, Zhang Shize, Chen Xi, and more than thirty students from the automobile R&D team were all taking notes in their small notebooks.
Yaoguang didn't record it. She came here to discuss something with Yang Fan, not because she was interested in cars.
Yang Fan also mobilized more than fifty workers to manufacture the chassis of Yang Fan's improved design on site. The I-beams were added to the cross beams and assembled using hot riveting.
Yang Fan decided not to let them take any more detours and built a car on the spot for them to see.
Let them thoroughly understand what parts a car is made of, how it is manufactured, and what the development ideas are.
"Sir, what is the suspension system?" Chen Xi asked.
"The wheels cannot be rigidly installed directly on the chassis. The connection between the wheels and the chassis is the suspension system. You see, using these elastic steel plates of different lengths to connect the wheels and the chassis is the simplest suspension system. Purpose
It is shock absorption to improve the comfort of the passengers. We use inflated rubber tires, self-lubricating pure copper bearings, elastic steel plates for shock absorption, and install them on the chassis steel beams to form a complete chassis system."
Then everyone sat here and watched the chassis gradually take shape under the hands of this group of workers.
Yang Fan's mansion is well-equipped with various machine tools and tools. It is convenient to cut metal. There is also a small stove. It is also easy to heat metal.
By noon, the chassis was finally ready, and the steering wheel and brake system were installed.
"Master, is your design to put the engine in the front?" Chen Xi asked, looking at the chassis. Because Yang Fan placed the steering wheel two-fifths of the way from the front to the rear of the chassis.
"Yes, the engine is mounted in the front. In the future, all our vehicles, whether they are cars, trucks, or buses, will all be designed this way."
"Sir, how are you going to burn coal? There is no place for workers." Chen Xi asked in confusion.
"There is no need to fill in the media. The car I designed will not use coal-burning, Newcomen-style steam engines. Nor will it use the coal-burning reciprocating steam engines that you have not yet finalized. The car I designed, the engine
It must be miniaturized. Because the car is not big to begin with, how can it have the space and load to transport goods with such a big engine.”
"You have to remember that every kilogram of weight reduction in a car is valuable. All equipment and parts are made while ensuring strength and durability. The lighter the better. And the more powerful the engine, the better.
, the more fuel-saving the better. The more comfortable the riding experience, the better. The larger the load, the better, the faster the better. The more flexible the control, the better. The wider the passability, the better. These requirements above are your development ideas for designing cars in the future.
.All designs must be centered around this goal.”
"I have asked the factory to make me a lightweight small boiler that burns heavy oil according to my drawings. This is what you see." Yang Fan asked the workers to carry up a small steam engine that was rushed out last night.
"This steam engine is made of cast aluminum, and the casting is very thin. The craftsmanship is very good." Yang Fan continued, "This material is the aluminum alloy used to make armor. Its weight is only one-third of steel, but its strength is several times higher.
"
Chen Xi already knew about Yang Fan's oil refining, and knew about gasoline, kerosene, heavy oil and other oils.
"Look, heavy oil is injected from here into the combustion chamber. I changed the pipes of the water tube boiler to vertical ones. This is better than the horizontally arranged pipes designed by Chen Xi. Water convection flows up and down, and the vertical pipes heat up quickly and are more efficient.
.”
Chen Xi nodded and said: "I understand. The heavy fuel is put in the fuel tank and enters the combustion chamber through the pipeline. As long as the driver moves the equipment, there is no need to arrange for people to fill in the fuel. You can also sit and drive, which is really good.
design."
"My steam engine is also a reciprocating steam engine, but it burns heavy oil. Heavy oil has high energy density and can travel long distances with very little carry. This condenser can condense the ejected steam into water, which can be recycled and used to reduce the fuel consumption.
The interval between refilling water. In this way, the car can go a long way before it needs to refill water.”
Yang Fan paused and said: "Stop building the Newcomen steam engine. Let's just leave it to the students. This steam engine can be used for farmland irrigation and mine pumping. This low-efficiency steam engine can be produced and sold in the future.
Now. You must hurry up and finalize the reciprocating steam engine,"
"In order to rush for time, I have ordered steam engine trains and rails from America. In the near future, I will lay tracks in the capital and build urban rail transit. When you come this time, you will first stay to familiarize yourself with how to maintain and use these locomotives, and lead a group of them.
The driver and maintenance engineer came out to finalize the first-generation reciprocating steam engine. The subsequent second-generation steam engine can learn from the design of these train locomotives."
At this time, the servants came pushing the food cart. Yang Fan stopped explaining and greeted everyone to eat.
The meal is very simple, with four dishes and one soup. It is a working meal. The staple food is rice, steamed buns, and salt and pepper rolls. The meat dishes are braised pork ribs, pot pork, scrambled eggs with tomatoes, and hand-shredded cabbage. The soup is hot and sour soup. The weather is cold now.
, drink some hot and sour soup to warm yourself up.
Everyone takes their own plates to prepare meals. This is the practice of Yang Fan's system and everyone is used to it. The master and his wife are also in agreement with everyone.
This chapter is not over yet, please click on the next page to continue reading! Several people were eating around a round table and discussing at the same time.
"Sir, do you mean that if there is a seat behind the driver, it is a car? If the chassis is longer and more seats are installed, it is a bus. If there are no seats in the back, if there is a compartment, it is a truck."
"Yes, but different models have different uses. The size, structure, strength, number of wheels, etc. of the chassis must be designed according to needs. The power and efficiency of the engine and gearbox must also keep up. In fact, the car really
There's nothing difficult about it, it's just four wheels and an iron shell."
Yang Fan's words caused a burst of laughter.
"I have seen several models of your reciprocating steam engines. Small and lightweight ones can be used as power systems for cars, medium-sized ones for trains and locomotives, and heavy-duty ones for ships. This is basically the development idea. In terms of fuel,
It can burn both coal and heavy oil. I will soon build a large-scale oil refinery here, and heavy oil will be fully supplied in the future."
"Sir, Mingyan contacted me and said that their marine propeller has been developed. They want to order a set of reciprocating steam engines to be used on the 1,000-ton clipper ship they are about to launch. They will use it to experiment with the first sail and
Steam engine hybrid boat.”
Yang Fan nodded and asked: "The large steam engine of your experimental model has not yet been finalized. This time it is just right to send one over for them to experiment at sea. They are still focusing on sail warships. It is estimated that it will take three years for the steam engine ships to mature.
Let them put it on Jeju Island first and slowly experiment."
"Sir, when will your train and locomotive arrive? My own design feels so crude. When you talk about it, I feel that the idea is so clear. I can't wait."
Yang Fan smiled and said: "It's almost time. Just wait for Yaoguang's notification. When the goods arrive, they will be transported to the capital by boat. Your Majesty has already agreed to lay the rail transit in the city this time. However, the condition is that I pay for it.
Widen the road along the way, otherwise the road will be unwalkable if a small train is installed."
Xiao Niangpi said: "Then we still need to demolish and build roads. It is equivalent to building three roads to form a closed line."
Yang Fan said: "His Majesty agreed to hand over these three roads to us for development. We will follow the model of Imperial City North Street, with cement hardening the road surface, improving the sewer system, and leaving space for laying double track in the middle. Shops will be developed on both sides of the street."
"We have developed so much land, can we sell it?" Xiao Niangpi asked worriedly.
After all, there are still so many open spaces on Huangcheng North Street that have not been fully developed. The funds invested will not be recovered for a while.
Yang Fan said: "This time we are reducing the land area. In addition to building roads, we are just developing commercial real estate on both sides of the road. We won't build so many in the community."
