Chapter 280 Radial Tires (Fourth update, please subscribe)
Radial, steel wire tires.
Although he had an idea, Li Yian really didn’t understand what radial tires were.
After all, he is really not a professional.
But from amateur to professional, all you need is... a system.
The system requires certain conditions to be activated.
For example, an opportunity to learn.
Whatever you say, do it as soon as you say it. Don't put it off, because things will just be put off again and again. So no matter what you do, the key is not to think about it, but to do it. This is the truth that Li Yian summed up as a laborer.
Because it was the weekend, he didn't want to disturb others, so he decided to go to the library to find some books to see if there were any books related to tires in the library, which might give him some inspiration.
To be precise, it activates the learning function of the system.
"Calculation and Design of Automobile Tires"
"Tire Design Technology"
"Tire Design Theory and Methods"
It must be said that this book was moved from Germany The library has a very complete collection of books, although most of the books are in German.
After selecting a few books from the science area, Li Yian planned to study them carefully.
To be honest, judging from the current situation in Borneo, the first pot of gold should indeed be tires. There is no way. This is the resource advantage. Borneo's rubber production accounts for 60% of the world's total production.
The industry most suitable for Borneo right now is the tire manufacturing industry, and Li Yi'an also planned this. Even when he was still in North Africa, he had already ordered equipment for tire production from the United States. When the troops arrived in Zamboanga At that time, production equipment with an annual output of 1 million tires arrived in Zamboanga. Why did the United States respond so quickly? Because tires are an urgent need. If tires can be produced in Borneo, they can be supplied to the U.S. military and allied forces in the Pacific nearby.
For this reason, the United States not only provided a loan for the tire factory in the Lend-Lease Act, but the equipment was provided by the tire giant Goodyear, and even the factory drawings were provided by Goodyear. Not only were installation engineers sent to assist in building the factory, but also production engineers were sent to guide production.
In a word, people are surprisingly generous when they have a plan.
Holding a stack of books, Li Yian went straight to the reading area, opened the books and started reading. As soon as I opened the book, the system popped up a series of prompts.
[Discovered in the location "Calculation and Design of Automobile Tires", you can learn the skill "Calculation and Design of Automobile Tires". Do you want to learn it? 】
Sure enough, System Dad is still as awesome as before. As long as you get the book, you can learn skills!
Li Yian quickly chose yes, and knowledge of skills quickly poured into his mind.
Lv.1 tire design skills not only allow Li Yian to understand the knowledge of tire design, but also the design characteristics and various rules of various tires.
“There are radial tires.”
The knowledge in his mind made Li Yian's lips curl up. He knew that the system could "smuggle technology".
The technical level of the current system is roughly equivalent to that of the early 1950s. Although it is only slightly imitated, for Li Yian, this is definitely a treasure trove of technology, and he can just choose to borrow it.
Then Li Yian opened the "Skill Information Exchange" of the system, and soon found the information about radial tires under the "Tire Design Skills" column.
“It actually costs 2000 experience points, but the technology is expensive!”
While sighing, he looked at the message “Whether to extract “Radial Tire Design” flashed on the light screen.” Click “Extract” "At the same time, along with the white light that was invisible to outsiders, a thick book with neither publisher nor printing time appeared out of thin air in Li Yian's hands.
Then, Li Yian looked at the information and "designed" the radial tires with a pen.
Once people become focused, they will forget time. Li Yian, who was obsessed with design, got up again in the evening. Although he did not have lunch, after leaving the library, he went straight to the industrial park. The tire company went.
As a key enterprise in the first phase of construction, Borneo Tire Company has completed the overall construction and the equipment in the factory has been installed. Although it has not actually been put into production, it has produced its first product at the beginning of the month. batch of tires.
Although it was already seven o'clock in the evening when we arrived at the factory, there were still many people busy in the factory area - the factory building was completed, but the greening of the factory area, office buildings and corresponding ancillary buildings were still under construction middle.
"The carcass cords of this kind of tire are not arranged crosswise with each other, but are nearly parallel to the tire section, like the earth's meridian arrangement, so I call it a "radial tire." Its cord angle is small, generally 0°. There is no maintaining intersection between the carcass cords..."
In the design room of Office Building No. 1, when Li Yian explained the design of radial tires, Weeks and several other engineers listened extremely carefully , At first they did not believe in the tires designed by Chief Li, but now with his explanation, these people are all keenly aware that this kind of tires will bring about earth-shaking changes to the tire industry.
“...When the tire is driving, the stress around the crown increases, which will cause circumferential stretching and radial cracks in the carcass. Therefore, the buffer layer of the radial tire uses a close-to-circumferential arrangement of curtains The line layer intersects with the carcass cord at an angle of 90° to form a rigid annular belt that is almost inextensible, fixing the entire tire and limiting the circumferential deformation of the tire. This buffer layer bears 60% to 70% of the internal stress of the entire tire. , becomes the main stress-bearing component of the radial tire, so it is called the belt layer of the radial tire.”
Weeks, the tire expert sent by Goodyear to guide the production, said from Li Yi’s explanation. Realize that traditional fibers certainly won't cut it.
"Sir, the material requirements for this belt must be very high!"
"Yes, the design of the radial tire belt is very important. It must have good rigidity. It can use multiple layers of large-angle, high-strength and difficult-to-stretch materials, such as steel wire..."
I originally wanted to say "nylon "Li Yi'an paused as he spoke, because Dupont would definitely worry about the application of nylon after the war. For him who wanted to take away the golden doll, he naturally stopped talking.
It took almost an hour for Li Yian to explain his design clearly, then looked at Weeks and the others and asked.
"How about it? When can we produce it?"
Looking through the design drawings carefully, Weeks thought for a while and said.
"The factory has a test workshop, and the raw materials are readily available, but there is no suitable steel wire. It requires very thin and high-strength steel wires as cords, so..."
Waiting for him to say After that, Li Yian said.
“You can also use Manila hemp. Although the performance is slightly inferior, it can still meet the basic needs.”
Manila hemp is sisal. Because sisal fiber is strong, it has long been used in In tire manufacturing, during the war, in order to obtain enough sisal to produce various materials including tires, the US military sent commissioners to production areas such as Africa, and the cord used in the factory in Borneo was woven from sisal. , because it is close to the Philippines, which was also an important producing area of hemp before the war, otherwise it would not be called Manila hemp.
And radial tires can be divided into three types according to different materials: full steel wire radial tires, semi-steel wire radial tires and full fiber radial tires. The carcass and belt layer of full-fiber radial tires are all made of nylon or other fiber cords. The belt cords should use low-elongation cords. This type of radial tire is generally used on low-speed cars or tractors. This type of tire is used Just right on a farm tricycle.
Since we are going to invent radial tires, we should get the patents for these three types of radial tires in our own hands.
Following other people's paths and leaving others with nowhere to go is the correct way for a time traveler to operate.
“After we get suitable steel wire, we can manufacture steel wire tires and tires mixed with steel wire and fiber wire. For now, let’s use fiber wire first.”
