Compared with clocks, bicycles are much simpler, but to build a light and durable bicycle also needs special materials, such as the main proportion of the body of the frame, later China in the sixties and seventies, because the basic materials are not developed, can only use ordinary steel pipes, which makes the bicycle dead, called the 28 bicycle.

The chain, sprocket and flywheel of the bicycle are all transmission parts, which are very easy to damage, and the quality of a bicycle depends on whether these stressed parts are durable, and it is also the place where imported bicycles are better than domestic bicycles.

In addition, a good bicycle does not need to be oiled on the chain, it is all supported by the excellent material of the chain, which is both smooth and wear-resistant, and has excellent self-lubricating function.

Of course, the bike's braking system must also be excellent, whether it is wheel brakes or disc brakes, brake pads are a high-tech material.

As a good designer, you must have a comprehensive understanding of the materials you can obtain, for Yang Wenli, it is what materials are available to the Royal Industrial Technology Group, and Yimi is the most suitable for the pot, although it is not the best.

Like frame materials, he has two materials, titanium alloy and aluminum alloy with light weight and high strength, but titanium alloy can be used in important uses such as engines, and the output is not high, so he undoubtedly chose aluminum alloy.

High-strength aluminum alloy is first cast into aluminum alloy bar, then extruded by raw and cold extrusion through a large extruder, and finally tempered.

If it is a general bicycle company, there is only straight aluminum, and if you want special-shaped materials, I'm sorry! No.

But Yang Wenli can, he can get the special-shaped material he wants by designing a unique extrusion mold.

So his design is unrestrained and full of imagination, the frame is not a rigid triangle, nor does it have to be a round tube, it can be flat, it can only have an upward arc of diagonal beams, no beams.

Yes, he borrowed from the beautiful design of later generations of sports bicycles, mountain bikes, and recreational bicycles, and planned to design several bicycles with different styles and shapes.

He emphasizes color contrast, giving people a strong visual impact, metal raw materials require the depth of black, the bright eye of silver, and then with white, yellow, blue, green, red and black paint colors, simple, but strong contrast.

Because Yang Wenli himself is demanding, with his extraordinary wisdom, it took him ten days to design three different styles of bicycles.

After the design is out, it is not equal to being able to manufacture, for example, he requires the black to be deep, there must be a metal surface treatment process, commonly known as frosted, and the silver must be the highest level of chrome plating process, which must be studied by him, because time waits for no one, and the company is waiting for the rice to be cooked?

"First polishing, then drawing, and then spraying extremely fine silica particles, the finer the better, and finally the surface passivation treatment."

Seeing that His Majesty was directing his guard technicians, doing a complex surface treatment process, what kind of frosting process, Wang Rucheng couldn't help but say on the side: "Your Majesty, what's the use of this? Isn't it superfluous to not be able to increase the strength of the material? ”

"Hey! You don't understand, the products produced by our company must be of high standard and high quality, which will set an example for enterprises from all walks of life, and indirectly prompt them to pay attention to product quality and appearance technology.

This will create a good social atmosphere, which is our responsibility.

If we are shoddy, other companies will think that this is the product standard, because we have always been at the forefront of the world, they lack the motivation to improve, people have no choice, and they think that this is a good product.

The appearance is very important, very important, and at the same time, after frosting treatment, it also has excellent anti-rust performance, which is a good thing to kill multiple birds with one stone, why don't we do it?

As for adding a few additional processes, just add more money, in short, our products are in addition to the production cost, plus the appropriate profit, is the final selling price. ”

"Oh! Wei Chen understood, Your Majesty is indeed as wise as the sea, which is not comparable to ordinary people such as me. Wang Rucheng slapped a small sycophant.

"Hahahaha! You! You! ......" Yang Wenli pointed at Wang Rucheng and laughed.

The company already had a chrome plating process, but the standard was not high, and it could not meet the requirements that Yang Wenli wanted, so he instructed the relevant team to improve it and improve the process standard.

The high-grade chrome plating process can also be used in the surface treatment of the next watch, which is also a good thing to kill several birds with one stone, so it is necessary to pay attention to it.

There are only brake pad materials, and the company does not have them for the time being, so Yang Wenli went to the material research group, and he put forward his own requirements and explained to them.

“…… Brake pad material is not only used in bicycles, horse-drawn carriages and future cars need it, so our brake pad material standards should be set a little higher.

Brake pad materials are divided into resin-based materials and ceramic-based materials, both of which are powder unsynthetic materials, which must have excellent stopping properties, but the strength cannot be higher than that of the wheel hub or brake disc, which is a dilemma.

The solution to this problem is to use brake discs to improve the wear resistance coefficient of brake discs, so that the material strength of brake pads can be improved to achieve the purpose of improving brake performance.

The brake pad material is generally made of toner plus aluminum powder, magnesium powder and other soft metal powders, and the copper wire is melted together with resin, which should have excellent heat resistance. The main braking performance is copper wire.

Clay can also be used to melt and cast at high temperatures, and the performance of ceramic-based brake pads is better, but it is also very difficult, because ordinary clay must be melted at high temperatures, so other materials have already melted.

Moreover, the friction coefficient of ceramics is quite high, much stronger than that of ordinary metals, so the first thing to damage is the wheel hub or brake disc, which is not allowed, and the economic efficiency is too low.

The correct method is to develop a special ceramic with a lower friction coefficient than the brake disc material and a relatively low melting point. ”

"Your Majesty, listening to you say this, we may only be able to study resin-based brake pads and brake discs, and ceramic-based brake pad materials are very difficult, and it is difficult for us to produce results in a short period of time." The head of the materials research group immediately answered.

"Yes, the current bicycle is completely sufficient to use ordinary resin-based brake pads, the weight of the bicycle is very light, and the brake pads will not make any difference.

However, ceramic-based brake pad materials will be used in future automobiles, as it has excellent braking performance and is an indispensable accessory for automobiles.

In addition, I would like to remind you that the brake disc cannot be solid, it must be hollowed out to improve heat dissipation and thus brake performance. ”

The advantages of Yang Wenli, a reborn person, are reflected in these inconspicuous places, which reduce many mistakes and significantly improve the development schedule.

If he doesn't say it, how will others know what brake material to use? There is only one same test, which takes a lot of time, for example, he does not say that the brake disc must be hollowed out, and others absolutely do not have this awareness, only in the experiment to find problems and improve the design.

That's why he was sure that he would never be able to develop a bicycle in a short period of time.
