Silver Overlord

The four-wheeled carriage on the first drawing was very beautiful. With Yan Liqiang’s painter, he was just a few strokes, and a beautiful and beautiful four-wheeled carriage was on the paper.

On the first drawing of the four-wheeled carriage, Yan Liqiang drew directly into the four-wheeled carriage of the former European nobility in his mind, the spacious and bright carriage compartment, such as the door of the door. There are also carriage steps for passengers to get on and off, two horse lanterns on the left and right sides of the carriage driver’s position, and the top of the carriage and the luggage compartment on the back. They are all on the paper, making people feel at ease.

Not to mention anything else, because of the unique characteristics of the four-wheeled carriage, the carriage of the carriage is as spacious as a house. Compared to such a four-wheeled carriage, all the two rounds of the Great Han Empire, even if it was before Yan Liqiang When the imperial capital city returned to Gan Prefecture, the “luxury car” that the shopkeeper gave him was very simple. It is no exaggeration to say that the comparison between the two-wheeled carriage and the four-wheeled carriage is simply the contrast between the motorcycle and Maybach. same.

Qian Su was so shocked that he opened his mouth. After looking at the first picture, he looked at the second picture below.

The second picture shows the structure in the carriage of the four-wheeled carriage. On both sides of the carriage, there are bright windows. In the carriage of the carriage, two seats that are as spacious as a sofa are placed directly face to face. It looks comfortable. Very incomparable, even if Qian Su did not take such a carriage, he just looked at it and was attracted by such a design.

All the two-wheeled carriages, because of the space limitations of the carriages, are unlikely to move such comfortable seats into the narrow and sturdy space. The two carriages of the Great Han Empire are either small benches or fixed in the car. The wooden board, the so-called luxury, is only a little bit of fur on the bench and the wooden board. Some of the female carriages are dedicated to the inside of the carriage. For the sake of comfort, you can directly get a soft collapse that can lie down and sit cross-legged. Naturally, it is not comparable to the painting by Yan Liqiang on paper.

“This is… a four-wheeled carriage?” Qian Su looked at the two drawings and looked at Yan Liqiang, his eyes flashing strangely.

“Yes!” Yan Liqiang said with a smile. “Is this not clear at a glance?”

Qian Su smiled a bit. “I have to say that you are really good at painting, but this four-wheeled carriage is not good. If the four-wheeled carriage is so simple, it will be made. Under the end of the day, I am afraid that it is a four-wheeled carriage. It!”

Yan Liqiang knows what to ask, and puts on a curious look. “Oh, I don’t know why this four-wheeled carriage is not easy to manufacture?”

“It is very simple to make it, but the practicality of this four-wheeled carriage is not strong. Why is it not strong? It is because the four wheels of this four-wheeled carriage are fixed on the body. Once you walk, you can’t turn at all! “Qian Su pointed to the four wheels of the four-wheeled carriage drawn by Yan Liqiang. “So now all the world is passing two-wheeled carriages, because the two-wheeled carriage can make a convenient turn on the road, a coachman I can control the four-wheeled carriage. I heard that there is an imperial capital city. It is the emperor’s throne, but the emperor only has to sit a few times, and can only go on a straight official road. If you lose a head, you have to have a lot of people toss, unravel the horses, lift the carriage, and it’s too much trouble…”

“What if I can solve the steering problem of the wagon?”

“Ah, how could it be…” Qian Su said habitually without thinking about it…

Yan Liqiang smiled and handed the third sketch he had drawn to Qian Su. The third picture shows the structure of the bogie connected to the front and rear wheels of the four-wheeled carriage. Figure.

As soon as I saw the picture that Yan Liqiang took, Qian Su’s eyes widened in an instant. After a few seconds, his hand holding the picture was so excited that he shook slightly.

Seeing the appearance of Qian Su, Yan Liqiang sighed. The principle of the four-wheeled carriage is actually not complicated. It is just a layer of window paper. As long as it is broken, everyone can understand it at a glance. The four-wheeled carriage that Qian Su said before can’t turn. That’s because everyone is habitually installing four wheels on the same fixed frame. Therefore, it is very difficult and practical to make such a four-wheeled vehicle to turn. Not high, in his last life, the famous “Qingming Shanghe Map” has a four-wheeled vehicle, but the kind of four-wheeled vehicle is a heavy-duty vehicle pulled by cattle. All the turns are made by pulling the car in front. The head cows were built with hard air and hard work. Such four-wheeled ox carts have been used in rural areas before the liberation.

To solve the steering problem of the four-wheeled carriage, it is very simple. As long as the limitations and inertia of the thinking are broken, the front and rear wheels are mounted on two different frames, and then the two frames are connected by an upright hard shaft. Together, in this way, the problem of four-wheel steering can be easily solved. This is the bogie of the carriage.

Yan Liqiang had thought about doing a four-wheeled carriage before, but at that time, the conditions were not mature, and it was not meaningful to make it, so it was not done, and this time on the way back to Gan Prefecture, Yan Liqiang was in the two rounds. After the tens of thousands of miles in the carriage, he finally felt pains and decided to get out the four-wheeled carriage for the benefit of the world.

Clothing, food, shelter, and transportation are the most profitable and demanding businesses. Once this four-wheeled carriage is made, Yan Liqiang has no doubt that it will definitely be popular. As the creator of the four-wheeled carriage, he cannot monopolize all the four-wheeled carriages. With his fame, he only needs to take over the highest part of the four-wheeled carriage, and the steady profit and money are coming to him. At the same time, he can also cultivate his own power.

In addition, the biggest advantage of the four-wheeled carriage relative to the ordinary two-wheeled carriage is that it has a strong load capacity and can greatly improve the carrying capacity of the carriage. For a person, the meaning of the four-wheeled carriage is not Big, but for a country like the Great Han Empire, which relies mainly on land to complete the flow of goods, this has an unusual significance – the convenience and efficiency of cargo transportation on land, first of all, will reduce the logistics and transportation costs of goods. It is conducive to the circulation of goods and people in a wide range, so that business can be greatly developed, commercial development, handicraft industry will follow development and prosperity, and production technology will have demand and Motivation, by this, will bring a series of changes…

Of course, if you want to build a high-end four-wheeled carriage, there is not enough a bogie for the carriage. This bogie will know how to get it when you see it.

Therefore, Yan Liqiang then handed a picture to Qian Su, which is a coil spring designed by Yan Liqiang for damping at the bottom of the carriage and the rear axle.

“This…what is this circle?” Qian Su looked at the picture and asked in amazement.

“This thing is called a spring!”

“Spring…” Qian Su repeated it. Obviously, some people still don’t know what the spring is. “What is the use of this thing?”

“It can be soft and hard, can be big and small, can stretch and shrink…” After saying this, seeing that Qian Su’s face was strange, Yan Liqiang reacted at once. “Cough, Uncle Qian, don’t I want to smash, this thing is used to shock the carriage during driving, increase the comfort of the carriage, and you will know when you make it!”

Qian Su laughed. “Do you know how to make this thing?”

“Of course!” Yan Liqiang looked at Qian Su in a serious look. His face showed a look of memories. “A few days ago I had another dream. In that dream, the god grandfather who taught me how to save people taught.” I am doing the spring!”

In an era without springs, springs are definitely “high-tech” products, and because of its special production process, Yan Liqiang can completely control the production process of springs in their own hands, so that others can see them in a short time. Seeing it, it can’t make it. From this, we can open the gap between the four-wheeled carriages they produced and the four-wheeled carriages produced by others, and lay the status of the “luxury car” produced by the Gan Prefecture Manufacturing Bureau in this era…

Rolls Royce among the four-wheeled carriages produced by Yan Shi is not a dream…

Qian Su suddenly looked at Yan Liqiang eagerly. “I am asking you for your strength?”

“What, Uncle Qian?”

“Can you talk to the god grandfather, I am always welcome to come in this dream, really, I am very sincere, I have been looking for such a master to learn the skills from an early age, let him teach me too trick!”
