Ang knew that the craftsmen did not understand the purpose of the springs, and he was not going to take the time to explain them, because explanations were never as convincing as experiments. Pen % fun % Pavilion www.biquge.info

"There is a newly-built carriage outside, and the officer has a drawing in his hand, and you follow the drawing, add the spring to the carriage, and do it immediately."

After inspecting the springs, Ang Lee immediately ordered these craftsmen to perfect the carriage, and this carriage was specially made by Ang Lee for the spring system, if the spring system is not added, the carriage will not be able to be used normally, and it will fall apart.

Dozens of craftsmen added different types of springs to different parts of the carriage according to Ang Lee's requirements, and finally after spending more than an hour, all the springs were assembled in place, thus forming the finished carriage.

"Li Shilang, all the springs have been assembled, you can check it."

A leading craftsman, respectfully debriefing.

"You don't have to check it, you put the horses on and sit a few people in them, and go around a few times around the week to see how it feels."

Li An looked at a strong horse next to him and ordered.

"Yes, Li Shilang."

Several craftsmen tied their horses to the front of the carriage, and ten more climbed into the carriage and sat on ten specially made seats.

"Let's get started!"

Under Ang Lee's command again, a craftsman sat at the front of the carriage, whipped the horses, and began to gallop around the limited area of the R&D center.

The terrain in this area is generally relatively flat, but in fact there are many small potholes, normal carriages driving on such a road surface, for the people inside, is a very painful thing, and at this moment, the carriage designed by Li An is different, not only the body is equipped with a spring shock absorption system, even the same spring shock absorption device is also installed under each seat, the surface of the seat is soft sheepskin, so, under multiple protection, the bumpy situation of the carriage will inevitably be greatly weakened, people sitting inside, It will also feel more comfortable.

After three laps, the carriage slowly returned and stopped.

"Li Shilang, we know the effect of this spring, I really didn't expect the spring to be so powerful, and the bumpy situation of the carriage has been greatly alleviated."

"Yes! Sitting in such a carriage is very comfortable, much better than the usual carriage. ”

After several craftsmen jumped off the carriage, they all expressed their excitement and praised the spring shock absorption system.

Li An is naturally very satisfied, although he did not personally experiment, but the car of later generations has been done many times, much more comfortable than the carriage of this era, and at this moment, the spring shock absorption system has been successfully invented, in the future, the people of Datang, if they want to go far away, they no longer have to worry about road bumps, especially the section of the railway is not passable, it is a necessary artifact for travel.

"Okay, a few of you take this carriage to play on the street, so that the people of Datang can come to experience this carriage equipped with a shock absorption system, so that it won't be long before the sales of the springs will not worry, and the people will become much more comfortable when they go out, and they will be more than one stone!"

Li An smiled lightly and made a very wise decision, such a comfortable shock-absorbing carriage, how can it be experienced by the nobles of the Tang Dynasty, in order to obtain the sales of springs in the future, in addition, there are also many carriages in the Western Regions, and these spring shock-absorbing systems can also be installed on the carriages of the Western Regions, so the spring shock-absorbing system still has the possibility of exporting, especially after the railway to Yumen Pass is unblocked, the transportation cost of these three thousand miles can be greatly reduced, and the feasibility of export is greater.

Watching several handymen drive the shock-absorbing carriage towards Chang'an City, Li An showed a satisfied smile on the corner of his mouth, and looked forward to the scene of the hot sale of the spring shock-absorbing system in the future.

"In the past month, you have taken turns to go to Chang'an City to show the shock-absorbing carriage, so that all the nobles and merchants in the Western Regions in the city know the benefits of this carriage."

Li An looked at the remaining handymen who were not very skilled, and ordered loudly.

"Yes, Li Shilang, the villain understands."

Subsequently, Ang Lee explained a few words, asking these craftsmen to continue to make springs and find ways to improve the production process and improve the performance of springs.

After some research and development, a larger mechanical drive wire making machinery was born, and can press more softened iron at a time, and the diameter of the iron wire is getting larger and larger, even thicker than a human finger, which can be used as a steel bar for ordinary buildings, of course, this also needs to be straightened and hardened, otherwise, the soft wire can not become a steel bar no matter how thick it is.

With thicker wires, Ang Lee can make thicker springs, which can be used in heavier machinery, such as steam freight vehicles, which can be equipped with these thicker springs to improve transportation performance, and the emergence of spring shock absorption systems also makes it possible to develop passenger steam cars.

After making the first batch of large springs, Li An immediately drew a drawing, let the craftsmen build passenger steam cars, under the premise that the freight steam car has been put into production, the passenger steam car almost does not need to be developed, the large system is the same, only need to slightly change the auxiliary facilities, in addition, of course, to install a spring shock absorption system, just like a carriage, not only to install shock absorption on the car body, but also to install shock absorption devices for all seats, with double shock absorption against bumpy roads.

Shock-absorbing carriages appear in Chang'an City every day, and according to Li An's requirements, let the people of the capital experience at will.

At the beginning, only the most ordinary people went up to experience, but after discovering the benefits, many housekeepers of aristocratic families appeared, and after the experience, they were taken aback and hurriedly told their masters, thus leading to a large number of orders for spring shock absorption systems.

With enough money to do things, with enough capital injection, the scale of the wire workshop and the spring workshop was quickly expanded, and these equipment could be mass-produced to meet the needs of the market.

In addition, Hu Shang of the Western Regions also found business opportunities, and ordered these spring shock absorption systems in large quantities, however, because the iron material is still relatively lacking, so, the production capacity can not keep up, many Hu merchants in the Western Regions can not buy a sufficient number of goods, after all, these advanced products must first meet the needs of the Datang market, as for export, it is necessary to wait until the Datang market is saturated.

Half a month after the invention of the spring shock absorption system, all the emperor's royal carriages in the palace were equipped with spring shock absorption systems, which greatly reduced the bumpiness of Li Longji to go to the scenic spots near the capital, which made the emperor who loved to enjoy great joy, and immediately issued a decree to praise Li An and gave Li An a lot of property.

Li An was not very greedy for money, but the emperor could think of rewards, Li An was still very happy, and his head was hot, and he distributed the money of these rewards to some craftsmen in research and development, so that they were also happy.

The craftsmen were encouraged by money, and their enthusiasm for developing new things was even higher, and they all worked and improved according to Ang Lee's drawings day and night.

The passenger steam car was quickly manufactured, and it was a passenger steam car with a spring shock absorption system, and the vehicle was integrated, but the front of the car and the middle of the carriage were completely separated, leaving only a small opening with tempered jade glass, which could allow the guests in the carriage to see the driver at the front of the car.

The front of the car is equipped with a powered steam engine, as well as equipment to adjust the speed and direction, and there are only two rows of seats equipped with spring shock absorption system in the carriage, a total of ten people can be seated, and the middle of the two rows of seats is a wide passage, which can put things and stand people, the side of the carriage is wooden, but it is equipped with a number of tempered jade glass, and a curtain is also installed inside, so that as long as the guests inside close the curtain, the people outside can not see the situation inside.

This is somewhat similar to the bus of later generations, however, the bottom of the four pairs of large iron wheels are very eye-catching, no way, now can not make rubber, let alone pneumatic tires, so, can only use iron wheels, this is definitely not small to the concrete road surface in the future, fortunately, the weight of the whole carriage is not very large, not a heavy vehicle, the destructive power of concrete is relatively limited.

After the steam bus was built, Li An immediately went to inspect it, and took several craftsmen in the development into the carriage and sat down, and ordered the steam bus to drive to Chang'an City.

"Boom, boom, boom......"

With the sound of the steam engine starting, the steam bus moved slowly, and after turning around the R&D center, it left from the gate of the R&D center and went straight to Chang'an City.

When passing by the Black Medicine Workshop, Li An saw Chen Xuanli, the general of Longwu who arrived at the R&D Center on horseback, through the car window, and immediately ordered to stop.

At this moment, Chen Xuanli was looking at the steam bus that was slowly stopping in amazement, and dismounted to greet him.

"General, are you here to inspect the Black Medicine Workshop?"

Li An opened the window of the tempered medicine jade car and asked loudly.

"Li Shilang."

Chen Xuanli was taken aback for a moment, and then said: "I have just finished inspecting and was about to return to the city, when I saw a big guy driving over, it turned out that Li Shilang was inside, why, he developed something good?" ”

"It's a steam bus, it's much more comfortable to sit in it than to ride a horse, so the general might as well get on the car with me and follow me into the city."

Li Ang invited with a smile.

"Okay, then you're welcome."

Chen Xuanli threw the reins of the horse to his entourage, strode into the carriage of the steam bus, and sat with Li An.

"These are all the talents you have under your hands?"

Seeing the four people sitting in the carriage standing up, Chen Xuanli spoke.

"Yes, they made this steam coach, sit down! There is no need to be polite to the general, the general is not an old-fashioned person. ”

Li An opened his mouth to introduce and asked the four craftsmen to sit down.

With the start of the steam bus, Li An and his party quickly approached Chang'an City, which was faster than riding a horse, and it was more stable, and it was more comfortable to sit inside.

"How's that, General, it's much more comfortable than riding a horse!"

Li An leaned back in his seat and asked.

"Comfortable, of course more comfortable than riding a horse, these days, the carriages in the capital are busy installing the spring system you developed, I also tried it myself, it is much stronger than ordinary carriages, and this car has been equipped with that thing!"

Chen Xuanli said rudely.

"Hahaha! It's called the spring damping system, which is specially designed to reduce bumps, and this car is of course also equipped with this system. ”

Ang Lee explained with a smile.

"Good! Sitting in such a comfortable steam car, of course, it will take a few more laps, hahaha! ”

Chen Xuanli happily decided.

When the steam car drove to the city gate, the guards at the city gate all looked at the big monster in amazement, but when Li An showed the token, these guards obediently gave way and watched the big monster enter the capital.

All the people along the way cast curious glances, and some children ran after the steam bus, as if they were competing with the speed of the steam car, of course, the result was only to be thrown farther and farther away.

For the sake of safety, Ang Lee chose to drive on the widest and least pedestrian-sparsely populated road to avoid hitting pedestrians with poor control.

And because the performance of the steam engine has long been stable, for this reason, the test run was carried out very smoothly, especially Li An and others sitting in the carriage, looking at the bewildered eyes of pedestrians outside the window comfortably, it felt quite comfortable.

After a turn in the capital, Li An asked the driver to drive the vehicle outside the Chunming Gate to feel the feeling of the steam bus driving on the concrete road, after all, the main roads of Datang will be paved with concrete in the future, first feel the feeling of the steam bus driving on the concrete road, in order to evaluate the commercial future of the steam bus.

After showing the token, the steam bus smoothly drove out of the Chunming Gate and drove onto the concrete pavement that had just been built some time ago.

"Not bad! It feels much more stable than in the city. ”

Chen Xuanli first sighed.

"Yes! The concrete pavement is smoother than the stone brick pavement in the city, of course, it will be more stable, this kind of steam bus still has commercial value, if the rubber tire is developed in the future, the effect will be better. ”

Ang Lee dreamed of it.

"Rubber tires, what's that?"

Chen Xuanli asked curiously.

"Well, it's the soft wheels, so that the car will be more stable, with less bumps, or even no bumps at all."

Ang Lee explained stiffly.

"Rubber tires are so powerful, when will Li Shilang be able to develop them?"

"Well, it's going to be a few years! The first step is to build a railway from Luoyang to Laizhou, and the second step is to build a large shipyard in the bay of Laizhou, with a steam engine as the power, build a large sea ship, and after the construction is completed, send it to the depths of the ocean, bring back rubber trees from a long distance, put it in Yazhou for planting, and then, you can produce rubber products in Yazhou, and use sea ships to transport them to Laizhou, and then from Laizhou to the capital by rail. ”

Ang Lee opened his mouth and said his idea.
