Shen Kuo was also confused, it was recorded in the classics that the Qin Dynasty "car on the same track" stipulated that the distance between the two wheels on the vehicle was changed to six feet, so that the distance between the wheels was the same. Why did the student say that the gallop he had seen was not so wide at all?www.biquge.info Who is wrong, is the book wrong, or is the student lying?

Su Song is also a very strict person, he carefully studied the historical books of the Qin Dynasty and found that the Qin carriage is very distinctive. There is a door at the back of the cabin and three windows on the left, right and front. The front window panel is a hollow diamond-shaped pattern, and the window panel can be opened, so that the owner and Mite's information can be exchanged. The windows on both sides can be pushed and pulled back and forth, and the window panels are also hollowed out with diamond patterns, so that the outside of the car can be observed from the inside, but it is difficult for people outside to see the inside of the car. Standing above the horse's head are the carriage braces, which are used to support the wheels and reduce the pressure on the horse during long breaks. The iron ring is added to the axle to grind the iron with the iron, and grease lubrication is added during the process, which enhances the firmness of the wheel and reduces the friction of the car bearing. Some wheels are made of hardwood and some are made of iron.

Most of the Qin carriages were two-wheeled vehicles, and their design varied depending on the purpose, some were suitable for loading, some were good for speed, and some were light and comfortable. I just said that there was an open-top carriage, in the shape of a convex shape, divided into two chambers, front and back, and there was a dome-shaped oval lid on the carriage. Some are "vertical cars", which are single-wheeled two-wheeled vehicles with a round umbrella on the car.

Tang Xun didn't know how to work as a carpenter, so he could only stare at the sidelines, watching Shen Kuo and Su Song have a hot time. The power of ancient carpenters is not something that ordinary people can imagine, and many epoch-making inventions almost all appeared in the form of carpentry first. For example, gears, the smart Chinese invented wooden gears very early and used them in many places. Since the Eastern Han Dynasty, gears of different shapes and uses have been widely used in water rotation and continuous grinding, guide cars, Jili drum cars and other equipment. There are also orange trees and wheels that use the principle of levers (all of which are tools used for pumping water from wells, and are still used in some northern rural areas), as well as ploughing carts, irrigation dumping carts, and drum carts, which do not need to be introduced, and some rural areas in later generations are still preserved.

In addition to these, there are also threshing fan carts (human-driven, mainly used to remove bran from grain grains. ）； borrowing water power to scoop rice; The hydraulic blower used for iron smelting is a mechanical device that uses a horizontal or vertical water wheel to drive the leather bag or wooden fan to blow air. There is also a wooden bellows, but it has not yet been invented in this different time and space, and it still uses a fan that rotates by hydraulic power. These instruments are extremely ingenious, and the wisdom of ancient carpenters can be seen. What's more, the legend is that Zhuge Liang invented the wooden ox and flowing horse, and the bus invented the wooden airplane, flying for three days and three nights, these are like myths in Lu Chengqi's eyes, I don't know if they are true or not. But it is an indisputable fact that the wisdom of the ancients is not inferior to future generations. Even though they don't know any principles, they are already using them to create one amazing piece of ingenuity after another.

Qin Chidao is not like this! Such ingenuity surprised Lu Chengqi from later generations. It is no wonder that he attaches so much importance to craftsmen, and since he has been awarded the subject of Chidao, he has been running to Royal Roads University from time to time.

Just when Shen Kuo and Su Song were puzzled, Lu Chengqi came to Royal University again and consulted Qin Chidao with them. After listening to Shen Kuo's confusion, Lu Chengqi thought about it for a while and knew what the problem was. Although Shen Kuo is smart, they are easy to drill the horns, and it is easy to fail to get out. They didn't expect that the six feet of the Qin Dynasty were different from the six feet of the Great Shun Dynasty. One foot of Qin is about 23 centimeters equal to later generations, and one foot of the Great Shun Dynasty is about 32 centimeters of later generations. There is a difference of almost ten centimeters in the middle, how can it be the same?

After Lu Chengqi said this, Shen Kuo and the others suddenly realized and said: "I never thought that Qin Liuqi is different from today's six feet, if it weren't for Your Majesty to wake up, the ministers still can't figure it out, it's really ashamed." ”

Lu Chengqi sighed: "You are too limited to the technology of the Qin Dynasty, when the Qin Dynasty, a large number of bronze weapons were used, but now a large number of iron tools are used. Qin Chi Road uses a track made of hardwood, why can't we cast the track with steel? What the ancestors could think of, the descendants should be able to think of. I just want the effect of galloping, as for the form, why do you stick to the galloping road of the Qin Dynasty? ”

Lu Chengqi's words were deafening, and he woke up Shen Kuo and Su Song, who were still immersed in the world of the ancients. They were ashamed to say, "Your Majesty is really ashamed to wake up the dreamer with a word. ”

Lu Chengqi said again: "Tang Qing is an expert in smelting steel, the three of you must work together, and listen to the opinions of these students, what can you do behind closed doors?" Although these students are not as knowledgeable as you, but three generals are better than one Zhuge Liang ("leather maker" is actually a homonym for "leather general", "leather general" means "deputy general" in ancient times, the original meaning refers to the wisdom of three deputy generals can top a Zhuge Liang, and it is said to be a "leather craftsman" in folk circulation), so many people, there will always be an idea. ”

The three nodded, and Lu Chengqi continued: "If the steel is not enough, you can try to build a section first; If you don't have enough horses, you can go to the Horse Warden to get them, or you can even come and tell me that I will allow you to go to the Horse Warden to pick horses. ”

Tang Xun suddenly asked, "Your Majesty, since the gallop is made of steel, is the carriage also made of iron?" ”

Lu Chengqi pondered for a while before saying: "Wheels, axles and other easily damaged parts can be cast in iron. However, durable parts such as carriages can often be made of wood. The money and silver of the imperial court are not very abundant, and they cannot withstand such consumption. In addition, there is not a lot of steel produced in blast furnaces, and good steel should be used on the blade, which you know better than me. Although I am not stingy with your money, I cannot waste it like this. ”

Tang Xun nodded, indicating that he understood. Lu Chengqi continued: "The key is to study the distance between each sleeper in the gallop, how to make the horses work tirelessly, speed forward, and reach a thousand miles a day. ”

Shen Kuo and Su Song responded and said, "Your Majesty is really a celestial scholar!" ”

Lu Chengqi waved his hand and said, "I can only give you advice, but you have to come up with the finished product, otherwise I won't be 'resigned'!" After speaking, Lu Chengqi laughed himself.

With this layer of "threat", the three of them really blossomed, patted their chests and said: "Since Your Majesty does not follow the Qin system, it is easy to do things over there, and the ministers are confident, within a month, the gallop and carriage can be done!" ”

Lu Chengqi nodded and said, "Since all the Qings are so confident, then I will wait and see." ”

These three are all scientific madmen, and now that they have a direction, the three of them immediately work together and cooperate with many students from Royal Roads University to study together. Tang Xun was the best at smelting, leading many blacksmith-turned-students to study the width of the track, the distance of the sleepers, and how to stop the horses.

Shen Kuo and Su Song are both proficient in carpentry, and they led the students who were born as carpenters to study the shape of the carriage, how to reduce resistance, and how to enter the gallop road......

Under the division of labor and cooperation, different from the carriage and gallop road of the Qin Dynasty, there was soon a final, and a section of galloping road was ready to be built on a trial basis, and a carriage was trial.
