Doomsday Bunker Upgrade

For Chen Xin, in order to obtain enough supplies, apart from his extremely inefficient and dangerous way of picking up garbage by himself, it is the simplest and most direct way to obtain supplies through Li Yulong.

Originally, the SWAT team was also a very suitable partner for cooperation, but now the SWAT team’s energy is focused on capturing terrorists, and naturally there is no extra energy to deal with the material exchange with Chen Xin.

Chen Xin also revealed to the SWAT team that he wanted to exchange more supplies, but the reply he got was that he needed to be temporarily postponed.

This is obviously because the SWAT team is unable to allocate enough manpower to deal with this matter. It can only postpone the matter temporarily and wait until the terrorists’ matters are dealt with before they can have time and energy to deal with the exchange of materials with Chen Xin. Things.

So Li Yulong has become the only channel through which Chen Xin can obtain supplies.

However, Chen Xin didn't show this. After all, the group friends of other survival groups could not exchange materials, but the materials they could exchange were too few, and few people could reach his home and exchange materials with him.

After receiving Chen Xin's request, Li Yulong moved quickly, and did not ask Chen Xinjiu to wait until he prepared the materials he needed and sent them to Chen Xin's home.

In addition to the used tires that Chen Xinyao this time, there are also auto parts that he and Li Yulong said before to rebuild his car.

"Brother Xiao Chen, I brought you what you wanted!" Li Yulong still came over in person, greeted Chen Xin, and said kindly to him: "For the sake of our diligence, you said That snow track wheel, can you make one for me first?"

Listening to Li Yulong's words, Chen Xin couldn't help showing a smile on his face, and smiled at him, "You don't need this for your RV? And with such big wheels, the matching snow track wheels are not easy to make."

Chen Xin was not deliberately rejecting Li Yulong. Just as he said, Li Yulong’s RV uses large snow tires, and the chassis itself is high enough, even in today’s environment where the road has more than one meter of snow. It can also travel smoothly, and there is not much demand for snow crawler wheels.

And the large tires naturally have to be equipped with large snow track wheels.

Compared with ordinary car tires, it may be the size of an ordinary person's knee. The tires equipped in Li Yulong's touring car can reach the chest of a person. Such a big tire needs to be equipped with snow track wheels, so naturally it must be larger. .

But increasing the size obviously does not mean making it bigger.

"How can this kind of thing be so rare that Brother Xiao Chen is so hard for you?" Li Yulong was immediately pleased, and while flattering Chen Xin, he also said to Chen Xin: "I don't want to experience how well this thing works. Well! If it works, this thing can also be a special product in the market, right?"

"Do you want to sell snow track wheels as a commodity in the trading market?" Chen Xin rubbed his chin while listening to Li Yulong's statement, but he did not object.

A trading market, in addition to providing a trading platform for other vendors, has its own unique products that others cannot imitate, which is the focus of attracting more customers and vendors.

Originally, what Li Yulong prepared for the trading market was the ground source heat pump obtained from Chen Xin. This is naturally enough to attract customers, but who would think that he can make too many products?

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

So the two quickly finalized a new cooperation agreement. Li Yulong provided materials and Chen Xin helped make snow track wheels.

And because Li Yulong felt that the technical difficulty of this thing was not very high, he also proposed that he hoped that Chen Xin would teach the people under his hands the technique of making snow track wheels, so that he would learn how to repair it no matter what.

After all, the snow crawler wheel is not the same as the ground source heat pump. Compared with the ground source heat pump, which does not require much maintenance after installation, the snow crawler wheel is an easy-to-wear consumable.

Although it does not mean that it will be broken after using it for a while, it is normal to replace worn out parts and repairs after a period of use.

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

Chen Xin nodded after thinking about Li Yulong's proposal to teach his subordinates.

However, Chen Xin did not say to teach them the production technology, but only agreed to teach them maintenance.

Although I regret that Chen Xin didn't agree to teach his subordinates the manufacturing technology, it is already very good to be able to master the maintenance technology, so Li Yulong did not feel any dissatisfaction, and readily agreed to this matter.

Not only that, Li Yulong also followed Chen Xin very enthusiastically, wanting to see how he made the snow crawler wheels.

Chen Xin didn't mind Li Yulong's move by his side. After the people under his hands had moved the supplies and materials they had sent into his storage room, Chen Xin also sat in front of the workbench, preparing to make the first pair of snowfields. Track wheels.

Ding Ning and Qin Lan, who were temporarily staying here, naturally surrounded them for the first time, curious to see how Chen Xin made things.

Faced with the onlookers of the three people, Chen Xin didn't care either. He directly used the system interface to retrieve a used tire from the warehouse and started the transformation.

In the system interface, a scrap tire that had been flattened with grooves was quickly melted, and then re-deformed and woven into a new look together with the steel wire lining inside. A rubber track component soon appeared. On Chen Xin's workbench.

Naturally, Chen Xin could see how this scrap tire was turned into a track component, but in the eyes of the three onlookers Ding Ning, Qin Lan and Li Yulong, what he saw was how Chen Xin cut a scrap tire, and then It is flattened, cut into a suitable size, and then finely processed into a track assembly.

"Brother Xiao Chen, your hand is really clever! A scrap tire in your hand can be used for fun!" Li Yulong couldn't help but exclaimed, even Ding Ning and Qin Lan beside him couldn't help but agree.

Chen Xin didn't care about the praise of the three, and said to Dingning: "Xiao Ding, help me get the parts made over there."

Hearing Chen Xin's order, Ding Ning naturally helped Chen Xin take the parts he made before and placed them in front of Chen Xin.

In addition to the crawler itself, the components of the crawler structure include driving wheels, road wheels, induced wheels, and supporting pulleys. The driving wheels are a mechanism that transmits power to the crawler through the meshing of gears and crawler teeth.

However, the snow crawler wheel made by Chen Xin is just a crawler component and does not require driving wheels to provide power. Therefore, he did not design this part on the snow crawler wheel, only the road wheel, the inducer and the supporting pulley.

As the name suggests, the road wheels are used for load-bearing and regular track; the inducer is responsible for inducing and supporting the crawler, and the supporting pulley is used to support the upper crawler.

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

As long as these wheels are assembled on the finished bracket, the track components are assembled, installed on these wheels, and finally the fixed components are installed, and a snow track wheel is completed.

Looking at the completed snow track wheels, Chen Xin felt that this thing looked rough enough.

But it doesn't matter. After all, the track itself is associated with the impression of silly, big and thick. As long as it works well, it doesn't matter if it is rough.

And this is also the consensus of Ding Ning, Qin Lan and Li Yulong who were watching Chen Xin.

As long as it is easy to use, why mind if it is rough or delicate?

In this kind of apocalypse, if you have to investigate whether the shape of something is good-looking or exquisite, it can only be said that you have a bad brain or you are too full.

"Brother Chen, is this the snow crawler wheel? How does this thing work?" Li Yulong looked at the snow crawler wheel made by Chen Xin~www.ltnovel.com~ and asked him curiously.

Chen Xin knocked on the assembled snow track wheels in front of him, and explained to the three onlookers behind him: "Through a backing plate, let the wheels fit into the slot, and then fix these fixing parts to ensure that this thing will not slip off. After that, only the wheels need to rotate to drive this transmission mechanism, and then the crawler wheels can be moved and the vehicle can be driven forward."

"Wow, isn't it convenient?" Ding Ning exclaimed in admiration.

Chen Xin nodded slightly: "Although it is not as powerful as to directly remove the wheels and replace the crawler structure in terms of transmission efficiency, this type of snow crawler wheel is much more convenient in terms of ease of use. It’s much easier to install it when you don’t use it and remove it when you’re not using it.

Listening to Chen Xin’s introduction, the three onlookers couldn’t help but nod their heads. They didn’t understand everything. They clearly distinguished the difference between directly changing tires and installing this type of track wheel, but it was obvious that Chen Xin did. This kind of crawler wheel is obviously more suitable for current use.

After all, most vehicles nowadays still have a wheel structure. If you want to remove the wheel and replace it with a track, the replacement process is not only cumbersome and troublesome, but also requires professional and technical personnel to operate. How can such track wheels only need to be placed on the ground and then drive Is it easy and convenient to go up?

Seeing the production of the first crawler wheel, Li Yulong couldn't wait to say to Chen Xin: "Brother Xiao Chen, make the other three too, let's install it and try the effect!"

Chen Xin nodded when he heard him say this, and said to him, "Go and help me bring some more used tires."

Hearing Chen Xin's instructions, Li Yulong hurriedly ran to Chen Xin's storage room.
