Chapter 192

For Chen Xin, in order to get enough materials, besides the extremely inefficient and dangerous way of picking up garbage himself, it is the simplest and direct way to get materials through Li Yulong.

Originally, the SWAT team was also a very suitable partner, but now the SWAT team's energy is focused on arresting terrorists, so naturally there is no extra energy to deal with the material exchange with Chen Xin.

Previously, Chen Xin also revealed to the special police that he wanted to exchange more materials, but the reply he got was that he needed to postpone temporarily.

This is obviously because the special police team has no way to allocate enough manpower to deal with this matter. It can only postpone this matter for the time being. Only after the terrorists have been dealt with can they have the time and energy to deal with the exchange of materials with Chen Xin.

So Li Yulong became the only channel for Chen Xin to obtain materials.

However, Chen Xin didn't show this. After all, the group Friends of other survival groups can't exchange goods and materials. It's just that they can exchange too few goods and materials, and few people can arrive at his home to exchange goods and materials with him.

After receiving Chen Xin's request, Li Yulong moved quickly. He didn't ask Chen Xinjiu to prepare the materials he needed and send them to Chen Xin's home.

In addition to the waste tires Chen Xin wants this time, there are also the auto parts that he and Li Yulong said were used to transform his car.

"Brother Chen, I've brought you what you want!" Li Yulong still came here in person, while greeting Chen Xin, he flattered him and said: "for our hard work, can you make me a pair of snow crawler wheels first?"

Listening to Li Yulong's words, Chen Xin couldn't help smiling and said to him, "your RV doesn't need this, does it? And it's not easy to make such big wheels and matching snow crawler wheels. "

Chen Xin didn't deliberately refuse Li Yulong. As he said, Li Yulong's RV itself uses large snow tires, and the chassis itself is high enough. Even in today's environment with more than one meter of snow on the road, it can drive smoothly, and there is little demand for snow crawler wheels.

And large tires, naturally, should be equipped with large snow crawler wheels.

Compared with ordinary car tires, which may be the size of ordinary people's knees, Li Yulong's RV is equipped with tires that can reach people's chest. If such a large tire is equipped with snow track wheels, it naturally needs to be bigger.

But to increase the size obviously does not mean to make it bigger.

"How can this kind of thing be difficult for you, brother Chen?" At the same time, Li Yulong also said to Chen Xin, "I don't want to experience how easy it is to use first! If it's easy to use, it can also be our special product in the trading market, won't it? "

"Do you want to sell snow crawler wheels as commodities in the market?" Chen Xin listened to Li Yulong's statement and rubbed his chin, but he didn't object.

A trading market, in addition to providing a trading platform for other vendors, has its own characteristics and other people can not copy the goods, is the key to attract more customers and vendors.

Originally, what Li Yulong had prepared for the trading market was the ground source heat pump obtained from Chen Xin, which naturally attracted customers. But who would think that he had too many products that could make money?

At least neither Li Yulong nor Chen Xin felt that way.

Therefore, the two soon concluded a new cooperation agreement. Li Yulong provided materials and Chen Xin helped to make snow crawler wheels.

Moreover, because Li Yulong felt that the technical difficulty of this thing was not very high, he also hoped that Chen Xin would teach his people how to make snow crawler wheels, and that they would learn how to repair them if they could not.

After all, the snow crawler wheel is different from the ground source heat pump. Compared with the ground source heat pump, which doesn't need too much maintenance after installation, the snow crawler wheel is a consumable.

Although it doesn't mean that it will be broken after one use, it's normal to replace worn parts after a period of time.

In particular, the rubber track used by Chen Xin is obviously worn and needs to be replaced regularly.

As for Li Yulong's proposal to teach his subordinates, Chen Xin nodded and agreed after considering it.

However, Chen Xin did not say that he would teach them manufacturing technology, but only promised to teach them maintenance.

Although Chen Xin didn't agree to teach his staff manufacturing technology, it was very good for him to master the maintenance technology, so Li Yulong didn't feel dissatisfied and readily agreed to it.

Not only that, Li Yulong is also very enthusiastic with Chen Xin, want to see how he made the snow crawler wheel.

Chen Xin didn't mind Li Yulong's following him. After his subordinates moved all the supplies and materials into his storeroom, Chen Xin sat down at the workbench and prepared to make the first pair of snow crawler wheels.Ding Ning and Qin LAN, who are staying here for the first time, naturally surround him. They are curious to see how Chen Xin makes things.

In the face of three onlookers, Chen Xin didn't care. He directly used the system interface to transfer out a waste tire from the warehouse and started the transformation.

In the interface of the system, a worn-out tire that had been worn flat was quickly melted, and then deformed again. Together with the steel wire inside, it was woven into a new look. A rubber track component soon appeared on Chen Xin's workbench.

In Chen Xin's eyes, we can naturally see how this used tire turns into a crawler component, but in the eyes of the three onlookers, Ding Ning, Qin LAN and Li Yulong, we can see how Chen Xin cuts off a used tire, flattens it, cuts it into a proper size, and then processes it into a crawler component.

"Brother Chen, you are really skillful! You can play with a scrap tire in your hand Li Yulong couldn't help exclaiming, even Ding Ning and Qin LAN couldn't help echoing.

For the praise of the three, Chen Xin didn't care, Chong dingning said: "Xiao Ding, help me get the parts made there."

Hearing Chen xinphen's instructions, Ding Ning naturally helped Chen Xin take the parts he had made before and put them in front of Chen Xin.

In addition to the track itself, the components of the track structure include driving wheel, load-bearing wheel, inducer and belt pulley. The driving wheel is a mechanism that transmits power to the track through the meshing of gears and track teeth.

However, Chen Xin's snow track wheel is just a track component, which does not need the driving wheel to provide power, so he did not design this part on the snow track wheel, only the load-bearing wheel, inducer wheel and belt pulley.

As the name suggests, the load-bearing wheel is used to load and regulate the track; the inducer is responsible for guiding and supporting the track, and the belt pulley is used to support the upper track.

In addition, although there are many supporting parts, the snow track wheel is not a tank track after all, and its structure is not so complex, so it is much simpler to make.

As long as these wheels are assembled on the fabricated support, then the track components are assembled and installed on these wheels, and finally the fixed components are installed, a snow track wheel will be finished.

Looking at the finished snow crawler wheel, Chen Xin felt that it looked rough enough.

However, it doesn't matter. After all, the crawler itself is associated with the impression of silly big black rough. As long as it's easy to use, it doesn't matter if it's a little rough.

This is also the consensus of Ding Ning, Qin LAN and Li Yulong, who are surrounded by Chen Xin.

As long as it's easy to use, why care if it's rough or delicate?

In this kind of doomsday, if we want to investigate whether the shape of something is beautiful or exquisite, we can only say that it's either bad brain or too full.

"Brother Chen, is this the snow crawler wheel? How do you use it? " Li Yulong looked at the snow crawler wheel made by Chen Xin and asked him curiously.

Chen Xin knocked on the assembled snow track wheel in front of him and explained to the three people watching behind him: "through a pad, let the wheel clip into the slot, and then fix these fixings to ensure that the thing won't slip. After that, just need the wheel to rotate and drive the transmission mechanism to make the track wheel move and drive the vehicle forward."

"Wow, isn't that convenient?" One side of Ding Ning issued a exclamation of admiration.

Chen Xin nodded slightly: "although in terms of transmission efficiency, it's not as powerful as directly removing the wheel and replacing the crawler structure, but in terms of convenient use, this kind of snow crawler wheel is much more convenient. It's much easier to install it when you need to use it and unload it when you don't use it."

Listening to Chen Xin's introduction, the three onlookers nodded. They didn't understand everything. They naturally distinguished the difference between directly changing tires and installing this kind of crawler wheel. However, it was obvious that this kind of crawler wheel made by Chen Xin was more suitable for today's use.

After all, most of today's vehicles are still wheel structures. It's not only cumbersome and cumbersome to replace the wheel with a crawler, but also requires professional and technical personnel to operate it. How can there be such a kind of crawler wheel that just needs to be placed on the ground, and then it's easy to drive the car?

Seeing the production of the first crawler wheel, Li Yulong couldn't wait to say to Chen Xin: "brother Chen, make the other three, let's try the effect on them."

Chen Xin heard him say so, also nodded, said to him: "to help me move a few waste tires."

Hearing Chen Xin's instructions, Li Yulong rushed to Chen Xin's storeroom.
