Chapter 281: The wave of inventions brought by the transportation industry

After Shangwen woke up, he looked at his own Yingyu with a smile on his hippie face. Shang Wen sighed.

"Hey, what's your anger?" Ying Yu cursed.

"You don't even know, what am I doing?" Shang Wen said.

"You are on the way back to Xianyang. I think you can play your best role in Xianyang. In the north, there is a place for war. It's not suitable for you." Yingyu said.

Shang Wen didn't want to answer. The large-scale development of modern chemistry comes from petroleum and coal. This is also the time when these two resources allowed mankind to enter the era of industrial civilization. Shangwen sat in the car, thinking about the price that mankind has to pay to develop industrial civilization.

In Xianyang, countless people are participating in such crazy inventions.

Because the logistics in the northern part of the Qin Kingdom all implemented a commercial mode of operation. A large number of carriages and horses began to appear. But the carriage and horse transportation formally separates separately and exists as a kind of industry. Make it more professional and professional.

The supply of materials in the north has gradually increased. Because of the continuous deployment of troops to the north, the large amount of materials hoarded in the north urgently needs to be digested in the interior. The carriage of vehicles and horses is very busy. Several generations of cart and horse production plants have appeared in China.

Hi old hi font size. As well as a large number of civil servants of various font sizes. Although the production is very large, the demand is even stronger. The transportation industry is profiteering. Qin State is in the transportation of the army. Implement no taxation. As long as you are carrying military supplies, everything will be distributed. As for the materials on the return journey, Shangwen suggested from the beginning that water should be released intentionally. King Qin agreed. So, this time and again. The cost of transportation is very low, but the profit is very high. Many people started to join in.

The huge demand makes it impossible for several domestic carts and horses to produce day and night to meet such a large demand. The coach and horse dealers are faced with a large number of coachmen and coaches who have obtained huge funds from the north. Now many people in all parts of the Qin State already know about the huge war supply demand in the north. At the same time, they heard from the gossip that the State of Qin would also use large-scale troops against the Yueshi. In this way, they almost invested all the money they had just earned. Insufficient money forced them to join forces and share stocks. After Qin State appeared for the first time, the second one quickly appeared. A large number of carts and horses have developed in this way.

With carts and horses, they need a lot of carts and horses. These carts and horses almost spared no expense to buy four-wheeled carriages that can be purchased, and the load capacity has been increased repeatedly. However, a certain imperial horse-drawn carriage factory in the State of Qin actually produced a six-wheeled carriage. The load capacity has almost doubled. However, it was short-lived because of the cost of a lot of horses, and the poor speed and handling performance. However, the emergence of this kind of six-wheeled carriage made some people begin to transfer to another type of transportation, and they began to try to put the steam engine directly on the carriage. For this reason, the Chess and Horses Company has built an eight-wheeled carriage on its own. But soon, such an experiment ended in failure.

The reason is that the steam engine is difficult to control. Without any drive shafts, simple mechanical equipment such as gearboxes, it is impossible to put them into production at once. The same is true of the experiment. After the steam engine was connected to one of the front driving wheels, it began to drive frantically. It was very difficult to control the direction and the speed could not be controlled. Directly lead to the failure of the experiment.

Failure did not stop the progress of other similar experiments. As the carts and horses traveled, the cart and horse factory began to issue huge bounties for craftsmen to develop such a large load. Cars and horses with good maneuverability.

Under the huge bounty. Many craftsmen start to take the time to develop, they think they should be able to get this bounty soon with their own invention.

Soon, various small inventions for carts and horses appeared. Camshafts, reducers, planetary gears, steering wheels, etc. These are a certain kind of parts to solve the problem of carts and horses, and all of them can be actually controlled.

But at this time, disagreements soon appeared. The tractors and trains designed and manufactured by the arsenal were quickly taken out by craftsmen for research. Tractors were originally used in agriculture, and they never thought about transporting them. And this part soon took the tractor as the research object and began to study it carefully. Their design goal is to be fast and convenient. They have experimented with the crawler design, but it is not very fast, and it is extremely heavy. Especially with the addition of the steam engine, the overall weight almost makes the crawler difficult to walk. The steam engine at this time has been upgraded for three generations, but its weight is still very large. It can't be fully miniaturized yet. It is impossible to be absolutely small. The experiment stopped here for the time being, and turned to research to replace the heavy steam engine.

The method was quickly found. They drew inspiration from the piston device of the hydraulic press of the steam engine. According to the principle of the steam engine, a more compact and small steam engine was developed. More crazier moves are behind. They need a substance that can fully burn in an instant, gunpowder, this military-controlled item, and become their first choice, because gunpowder can burn in an instant, which is the prototype of an internal combustion engine. In a cast piston cylinder, they ignited gunpowder. Gas after burning gunpowder. The piston is pushed up and down. Driven linkage rod. Start exercising. The experiment was considered a success because their idea was correct. But after the gunpowder is ignited, how to ignite it again. Moreover, the residue after burning the gunpowder is very much. The lubricity of the piston is greatly challenged. This experiment has temporarily stalled, and they need a new substance. To move forward.

The other one pursues large carrying capacity. When designing the train, Shangwen did not issue the rail plan. Because production is not allowed to do so. But now when developing the carriages, they have come to this point ahead of schedule. The design of the steam engine. Just install it. Variable speed valves have reduced the steam supply and other measures have made it easy to control the speed of this kind of carriage. Moreover, the size limit of the steam engine is not very strict. They can build a carriage alone to carry the steam engine. The fuel in the back can also use a carriage, and a larger steam engine can drag them. In this way, the number of carts and horses that can be mounted behind can be greatly increased. Experimental facts also prove this point. When driving in a straight line, the steam engine can freely control the speed and mount a lot of wagons and horses. But then a problem emerged. direction. Directional control.

The highway from Xianyang to Guyang is not a straight line. In order to speed up, the straight line had to pass through many gullies directly. In order to reduce the difficulty of the project. The project chose to bypass these gully, this design. Obviously it does not meet this requirement.
