Chapter 426

The four-wheel carriage on the first drawing is very beautiful. With Yan Liqiang's painter, a luxurious and beautiful four-wheel carriage jumps on the paper with only a few strokes.

Yan Liqiang drew a four-wheel carriage on the first drawing directly according to the four-wheel carriage he still had an impression of in his mind. The spacious and bright carriage, the carriage door like the door, the carriage bench convenient for passengers to get up and down, and the two horse lamps on the left and right sides of the coachman's position in front of the carriage, There are also places on the top and back of the carriage where the luggage rack is placed, which jump on the paper and make people excited at first sight.

Not to mention anything else, because of the unique characteristics of the four-wheel carriage, the carriage of the carriage is as spacious as a house. Compared with such a four-wheel carriage, all the two-wheel carriages of the whole Han Empire, even the "luxury car" given to him by shopkeeper you when Yan Liqiang returned to Ganzhou from the capital of the emperor, are instantly primitive, which can be said without exaggeration, The comparison between a two wheeled carriage and a four wheeled carriage is the same as that between a motorcycle and Maybach.

Qian Su opened his mouth in amazement. After looking at the first picture for a few times, he looked at the second picture below.

The second picture shows the structure of the four-wheel carriage. On both sides of the carriage are bright windows. In the carriage, two spacious seats like sofas are placed directly face to face. It looks very comfortable. Even if Qian Su hasn't sat in such a carriage, he is attracted by this design just after a glance.

Due to the limitation of carriage space, it is impossible for all two wheeled carriages to move such comfortable seats to the narrow space. The two wheeled carriages of the whole Han Empire are small benches or wooden boards fixed in the car. The so-called luxury is only to pad a little fur on the benches and wooden boards at most. Some women's special carriages are for comfort, You can directly get a soft collapse that can lie down and sit cross legged. In terms of comfort, it is naturally not comparable to Yan Liqiang's painting on paper.

"Is this... A carriage?" Qian Su looked at the two drawings and Yan Liqiang. A look of surprise flashed in his eyes.

"Yes!" Yan Liqiang smiled and said, "isn't it clear at a glance?"

Qian Su smiled bitterly. "I have to say, Li Qiang, you are really good at painting, but this four-wheel carriage is not good at all. If the four-wheel carriage can be made so simple, I'm afraid it's all four-wheel carriages running under the sky!"

Yan Liqiang asked clearly, pretending to be curious, "Oh, I don't know why this four-wheel carriage is not easy to make?"

"It's actually very simple to manufacture, but the practicability of the four-wheel carriage is not strong. Why not? It's because the four wheels of the four-wheel carriage are fixed on the body. Once you walk up, you can't turn at all!" Qian Su pointed to the four wheels of the four wheeled carriage drawn by Yan Liqiang and said, "so now the two wheeled carriages are popular all over the world, because the two wheeled carriages can turn easily when walking on the road, and one coachman can control them. I heard that there are four wheeled carriages in the imperial capital. They are the emperor's throne, but the emperor only takes them in a few times, Moreover, you can only walk on a straight official road. If you want to turn around, a lot of people have to toss around, untie the horses and lift the carriage. 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 Li forced a smile and handed Qian Su the third sketch he had drawn. On the third picture, he drew the structure diagram of the bogie connected with the front and rear wheels at the bottom of the four-wheel carriage.

As soon as he saw the picture taken by Yan Liqiang, Qian Su's eyes widened in an instant. After a few seconds, his hands holding the picture trembled slightly with excitement.

Seeing Qian Su's appearance, Yan Liqiang sighed. In fact, the principle of the four-wheel carriage is not complicated. It's just a layer of window paper. As long as it is pierced, everyone can understand it. Qian Su said before that the four-wheel carriage could not be turned because everyone habitually installed the four wheels on the same fixed frame. Therefore, it was very difficult to turn such a four-wheel carriage and its practicability was not high. In his last life, there were four-wheel carriages in the famous picture of the river at Qingming Festival, but that kind of four-wheel carriage was a heavy-duty vehicle pulled by cattle, All the turns were made by several cows pulling the cart in front. Such a four-wheel ox cart was still in use even in the rural areas of China before liberation.

To solve the steering problem of four-wheel carriage, it is very simple. As long as we break through the limitations and inertia of thinking, install the front and rear wheels on two different frames, and then the two frames are connected together with a vertical hard shaft. In this way, the problem of four-wheel steering can be easily solved. This is the bogie of carriage.

Yan Liqiang had thought about making a four-wheel carriage before, but at that time, the conditions were not mature, and it didn't make much sense to do it, so he didn't do it. This time, on the way back to Ganzhou, Yan Liqiang bumped tens of thousands of miles in the two carriages, he finally thought hard and decided to make the four-wheel carriage for the benefit of the people all over the world.

Clothing, food, housing and transportation are the most profitable and demanding businesses. Once this four-wheel carriage is made, Yan Liqiang has no doubt that it will be popular all over the world. As the creator of the four-wheel carriage, even if he can't monopolize all the four-wheel carriages, with his fame, he only needs to occupy the most high-end part of the four-wheel carriage, Then there will be a steady stream of profits and money rolling towards him. At the same time, he can also cultivate his own power.

In addition, compared with ordinary two wheeled carriages, the biggest advantage of four wheeled carriages is that they have strong carrying capacity and can greatly improve the carrying capacity of carriages. For a person, these four wheeled carriages are of little significance, but for a country such as the Han Empire, which mainly relies on land to complete the circulation of goods, This is of extraordinary significance - the convenience and efficiency of land cargo transportation will first reduce the logistics and transportation costs of goods and facilitate the circulation and migration of goods and personnel in a wide range. In this way, commerce can be greatly developed, and the handicraft industry will develop and flourish with the development of Commerce, The improvement of production technology will have demand and power, which will bring a series of changes... Of course, if you want to manufacture a high-end four-wheel carriage, it is not enough to have only one carriage bogie. Others will know how to do it at a glance. Therefore, Yan Liqiang then handed Qian Su a picture. On that picture, Yan Liqiang designed a coil spring for damping at the connection between the bottom of the carriage and the rear axle... "What's this... What's this circle?" Qian Su looked at the picture and asked in amazement“ This thing is called a spring! "“ "Spring..." Qian Su repeated, obviously still some don't know what spring is, "what's the use of this thing?"“ It can be soft and hard, big and small, and can stretch and shrink... "After saying this, Yan Liqiang suddenly reacted when he saw Qian Su's face strange." cough, uncle Qian, don't think about it. This thing is used to shock the carriage and increase the comfort of the carriage during driving. You'll know when it is made! " Qian Su smiled, "do you know how to make this thing?"“ Of course! " Yan Liqiang looked at Qian Su solemnly, with a look of memory on his face. "A few days ago, I had another dream. In that dream, the immortal grandpa who once taught me how to save people taught me how to make springs!" In an era without springs, springs are definitely "high-tech" products, and because of their special production technology, Yan Liqiang can completely control the spring production process in his own hands, so that others can see it in a short time, but can not make it. Therefore, he can open the gap between the four-wheel carriages produced by them and those produced by others, Establish the Jianghu status of the "luxury car" produced by Ganzhou manufacturing Bureau in this era... Rolls Royce in Yan's four-wheel carriage is not a dream... Qian Su suddenly looked at Yan Liqiang eagerly, "Li Qiang, I beg you something?"“ What's up, uncle Qian? "“ Can you tell the immortal grandpa that in my dream, he is always welcome to come. Really, I have a heart to the Tao. Since I was a child, I wanted to find such a master to learn skills and let him teach me some tricks!
