By linking my account to the check-in system, I became a leisurely traveler.

Chapter 234 The Suspension of Dimensional Reduction Attack

The scene flashes quickly across the workshop, showing precise measurements, robotic welding, and engineers creating computer models, accompanied by calm and professional background music. Then, the scene shows the factory manager facing the camera.

"I recently came across a video of a streamer who was going to independently modify a Unimog campervan. First of all, I have to give a thumbs up to his courage and love for travel."

"But as someone who has been working in the Unimog modification industry for more than ten years, I can't help but want to say a few words from a professional perspective after reading this—modifying a Unimog campervan is not something that can be done just by having strong hands-on skills."

"Let's start with the most crucial issue: the chassis."

"The Unimog's soft frame is the soul of its off-road capabilities, capable of producing 15 to 30 degrees of torsion under extreme conditions, which is to keep the wheels always in contact with the ground."

"But the RV body is rigid. If the body is welded directly to the frame, a pothole on the road to Tibet will cause the frame to twist but the body to not. As a result, either the body will crack or the internal furniture and pipes will be torn off."

“We spent three years iterating on the secondary suspension technology to enable the chassis to suspend on the frame and use sufficient travel to counteract torsional forces. This is not something you can just put together by buying a suspension kit yourself.”

"Let's talk about the safety details that people tend to overlook."

"The most common problem with illegally modified RVs is the messy electrical circuits. The refrigerator, air conditioner, and water heater in the RV all rely on electricity. The current of the 12V system can be close to 8A. The sparks generated by the frequent starting and stopping of the pressure switch could cause a fire at any time."

“Our circuits are all modularly designed, with each circuit having its own independent relays and fuses. They also have to pass high and low temperature and vibration tests. Not to mention the braking system, after adding a box weighing several tons, the original brakes are definitely not enough. We have to recalculate the braking torque and upgrade the calipers and brake discs. This is directly related to the life and death safety on Route 318.”

"I'm not trying to be pessimistic, but I've seen too many cases of privately modified RVs. For example, the water pump stopped working on the way to Tibet, and after investigation, it turned out that the pressure switch contacts were burnt and stuck. The RV body leaked water in the rain because the structural seals were not done. Some owners even changed the weight distribution and their braking distance increased by 5 meters out of nowhere."

"These problems can be repaired in the city, but in the no-man's-land of the 318 National Highway, you'll really be left helpless."

"Leave professional matters to professionals, not for the sake of monopolizing the market, but to reduce the risks of your trip. After all, no one wants their eagerly anticipated journey to turn into a series of repairs and ordeals."

At the end of the video, the screen shows the modified Unimog RV passing off-road and rain tests, with the caption "Legal and compliant, safe and reliable".

Li Younan watched the video in silence.

He was perfectly aware of the RV manufacturer's motives in filming the video. Although the content itself was largely harmless, their true intentions remained the same few things...

By establishing a professional persona and capturing users' minds, highlighting the technical barriers in the industry by breaking down the technical difficulties that are difficult for ordinary people to grasp, the company aims to create the perception among potential consumers that modifying Unimogs requires a professional manufacturer. This strategy leverages trending topics to attract traffic and convert potential customers.

Of course, another motivation may be to avoid negative risks in the industry. After all, if Li Younan's modifications result in safety accidents or legal disputes, it may trigger a crisis of public trust in Unimog motorhomes.

Pointing out the potential risks and illegality of unauthorized modifications in advance not only distinguishes them from non-professional modifications but also indirectly emphasizes the necessity of legitimate manufacturers, thus maintaining the industry's reputation.

Of course, whatever the other party's motives are, it doesn't really affect Li Younan.

Although the current online public opinion environment is somewhat bad for him, as long as he grasps the main contradiction, which is that he does indeed have the ability, he doesn't need to care too much.

At times like this, it's best to let the bullets fly a little longer. The bigger the current turmoil, the better the later reversal will be.

This kind of problem can be easily solved if one is strong enough to withstand the test.

……

As stated in the video released by Unimog Motorhomes, the first problem Li Younan needed to solve was the secondary connection between the container and the vehicle chassis.

If this area is not handled properly, it is indeed as the other party said, that the entire box will deform due to the bumps.

Despite its all-aluminum alloy casing, the real advantage of all-aluminum alloy is its lightweight nature rather than its rigidity.

Of course, there is also a simple solution: directly purchase the connecting suspension from Unimog RV factory, which collaborates with Li Younan, which can also solve this problem.

In fact, the RV manufacturer thought the same way, so when Li Younan arrived at the factory on the first day, the manager of the Unimog vehicle factory started promoting their connecting suspension to Li Younan.

Just then, another boss's car arrived, and the staff in the parking lot were introducing their connected suspension to that boss. The manager then took Li Younan over to listen in.

"Mr. Zhou, rest assured, our secondary suspension is absolutely stable and can control the bumps to a very small range. It also uses airbags, which is an industry-leading level."

After listening to the staff member babbling on and on in English, the boss shook his head and said, "I don't really understand this. Just get it done for me."

The staff member said with a smile, "Don't worry, boss."

Only then did the manager look at Li Younan and say, "Teacher Li, you definitely can't fix this suspension by yourself. We've seen that video, but don't worry about what it says. We'll fix this suspension for you."

However, Li Younan already had his own ideas about the suspension. He smiled and shook his head, saying, "Your suspension is pretty good, but I plan to design it myself."

The manager's lips twitched slightly: "Teacher Li, this suspension..."

He assumed that Li Younan was planning to buy suspension from other manufacturers and wanted to say something more.

However, Li Younan didn't explain further.

On that day, Li Younan arrived at BYD's headquarters by plane.

Li Younan already had a clear idea of ​​how to design the suspension system.

In fact, the secondary suspensions designed by those Unimog RV manufacturers were quite good, but for Li Younan, they were still not top-notch.

Because these suspensions are all passive suspensions, no matter how little the bumps are controlled, you will still feel them clearly inside the car.

The carriages will be filled with a lot of items, and if they are not secured, the bumps and jolting could easily cause some equipment to malfunction.

Although the probability of this is relatively small, Li Younan felt that if he was going to do it, he should do it to the best of his ability.

BYD currently possesses the most advanced suspension technology in China.

Chatting with Li Younan was a very simple thing, without much beating around the bush. Li Younan successfully arranged to meet the engineer in front of him by relying on his influence.

After Li Younan briefly explained his purpose, the BYD representatives present exchanged glances. The renowned suspension engineer in the industry frowned: "You mean you want to use our Yunlian Z electromagnetic suspension system for the Unimog's secondary suspension?"

Li Younan nodded: "Yes."

This is Li Younan's vision—BYD's Yunlian Z electromagnetic suspension!

Currently, this is the suspension system used on the Yangwang U7.

As an off-road vehicle, the Unimog certainly cannot use electromagnetic suspension as its main suspension.

On the one hand, the Unimog is, after all, an oil-powered vehicle; on the other hand, in those harsh road conditions, a metal suspension structure is still needed for greater stability, and spare parts are also easier to find for repairs.

However, as a secondary suspension connecting the car body and the main beam, the Yunlian Z has an unparalleled advantage!
Because it does not need to come into direct contact with bad roads, the disadvantages of the Yunlian Z electromagnetic suspension are offset.

The rest are all advantages.

First of all, this type of suspension has an extremely fast response speed and extremely high control precision, almost hundreds or thousands of times faster than traditional active suspensions, not to mention compared with the passive suspensions of those manufacturers.

They are products of two completely different eras.

If properly adapted, it can make the entire Unimog's cabin move without any bumps, as if on flat ground.

It's even better than the original suspension on the U7!

In addition, in the event of an emergency, the Unimog Z can actively raise the vehicle body on the side of the collision to disperse the impact energy, which can greatly enhance safety for a vehicle like the Unimog that often undertakes long-distance off-road trips.

Meanwhile, when Li Younan drives the Unimog into the wild, the linear motor of the Yunlian Z can convert the kinetic energy of the bumps into electrical energy to recharge the battery.

Find a girlfriend, and you can convert certain indescribable actions into electrical energy at night.

With his physical condition, he must have charged up to a fraction of a kilowatt-hour in one night!
Ahem... I've gone off on a tangent.

The Yunlian Z electromagnetic suspension involved thousands of PhDs and over ten thousand people in its research and development, far surpassing the so-called secondary suspensions developed by small RV manufacturers.

In every sense, if the Yunlian Z electromagnetic suspension could be applied to his Unimog, Li Younan's secondary suspension would be a game-changer for any other brand of motorhome!

However, after thinking for a moment, the BYD engineer slowly shook his head.

Li Younan raised an eyebrow slightly and quickly said, "Price is not a problem. I can even help your company promote Yunlian Z."

The engineer smiled but didn't say anything. However, the general manager of Yangwang spoke up, "Mr. Li, you misunderstand. It's not that we care about that... It's like this, you probably don't understand the working principle of this kind of suspension. It needs to be adapted."

At this point, the engineer finally spoke up, adjusting his glasses and saying, "Yes, that's right. The Cloud Carriage Z isn't something you can just buy and use immediately."

"If we want to install the Yunlian Z, we need to redesign the electronic control assembly according to the new application scenario, and we may even need to program a new control program separately."

Then, the manager sighed slightly and said with a smile, "So, Mr. Li, if you want to purchase our Yunlian Z electromagnetic suspension, strictly speaking, it's not just about buying a suspension system. You'll also need a team of electrical and software engineers to participate in the entire modification process of your car..."

"And the price of this part... even if we give you a discount, it will still start at least in the seven figures! This cost is too high for you, so we do not recommend that you use our Cloud Carriage Z electromagnetic suspension."

Li Younan was somewhat touched by the other party's reasoning, shook his head, and said, "Don't worry about that, I have a way to adapt it."
