My Strength Does Not Allow Me to Low-key

I opened a new book: The End of the World: My house can be upgraded, my brothers help to collect it, and give me some recommendations!

******************

The task of the future R&D center in Germany is very simple.

No need to do anything else, on the one hand, study various European electric vehicle policies, and then apply them to future cars.

On the other hand, it is to study the chassis.

How can the future car chassis be tuned to have a more advanced sense is one of their main research and development directions.

Don’t think about it, the chassis, it’s not easy?

The big deal is to buy a Mercedes-Benz or BMW car, and then we can copy the chassis of others.

But in fact, do you think we have never done this before?

From the earliest Yellow Sea Benz, to the later Lufeng Land Rover, to the later Baoshitai.

These car companies are not copying Mercedes-Benz, BMW and Porsche, copying from scratch to toe.

From the car's shape, appearance, to the chassis.

It can be said that except for the engine and transmission, everything else is the same as those luxury cars.

But actually!

You will know as long as you run.

People's chassis tuning is really based on technical skills, this is really true.

First of all, people will consider your body and weight, and then let your car run and observe your driving posture.

For example, when starting, the front of the car will lift at a high speed, and the rear of the car will lift at what speed when braking.

Also in the process of driving, when cornering, how fast the car body will tilt seriously.

Then when you pass the speed bump, what kind of feedback the body will have.

Integrate all the feedbacks together, and find an optimal balance between various data.

Then, according to this balance point, the torque bearing and deformation space of each support member on the chassis is set.

Everyone should know that when the car is driving, the chassis actually has to continuously absorb the impact of ground feedback, so the support parts of the body chassis are constantly changing and adjusted to cushion the impact.

The key to chassis tuning is actually to set an optimal variation range for these chassis supports.

In this way, when several supports have undergone buffer changes, the feedback to the body is the one that makes the driver feel the most comfortable and confident.

Of course, the setting of the change interval of each support is also related to the weight of the body, the power of the body, and the material of the support itself.

The tuning of high-end cars will naturally be more advanced because of the good materials.

And ordinary civilian cars, because the materials used are common, so they can test their skills the most.

For example, many people don’t understand that German cars, especially Volkswagen.

You said that the weight is not much heavier than that of Japanese cars. In terms of fuel economy, they are not even as good as Japanese cars.

Moreover, the later repairs and maintenance are more expensive than Japanese cars, but why he bought them more expensive than Japanese cars!

Hey there! This is expensive, it is expensive for this chassis tuning.

Anyone who has driven a German car and a Japanese car knows that even the lowest-level A-class car, even the Corolla, can't compare with the Sagitar.

The difference lies in the chassis.

Although this level of car, there is no need to talk about the sense of luxury.

But when it comes to giving feedback to the driver's confidence, that's not the same.

For example, on a 100-kilometer high-speed, you can drive a German car very easily. You can pinch the steering wheel with two fingers, and you won’t feel frustrated.

But if you are driving a Japanese car, you hold the steering wheel firmly with both hands, and you have to keep your eyes on the road and keep your eyes on it.

This is the difference!

A good chassis can bring great confidence to the driver.

Of course, the best one is the American car.

The reason why Japanese cars can compete with German cars and American cars is actually fuel-efficient and cheaper maintenance.

In the past, our traditional car companies paid little attention to chassis tuning.

I thought that as long as I copied the chassis structure of those European and American luxury cars, it should be about the same.

As everyone knows, the driving experience here is very different.

And the gap between us in the field of traditional car manufacturing and traditional world-class car companies is far more than just chassis tuning.

Chassis tuning can only say whether it can give the driver confidence or experience a sense of high-level.

In terms of performance, it depends on the matching of the engine and the transmission.

In this regard, we are farther away from world-renowned car companies.

Originally, we did not have an automatic transmission, so if we want to use an AT transmission, we can only buy it from Aisin or ZF.

Otherwise, you can only find Getrag or BorgWarner to buy the technology, and ask someone to help us develop the dual-clutch.

Then it is matched with the engine.

Although in recent years, the technology of dual-clutch transmissions has also made great progress.

The problem is that due to the inherent design flaws of the dual-clutch transmission, it is always unavoidable to have a sense of intrusion when it is creeping at low speed.

To put it bluntly, it was just driving, and suddenly felt kicked.

This feeling is quite low-end, while CVT transmissions will not, but CVT transmissions have a fatal flaw, that is, they cannot withstand high torque.

In other words, rapid acceleration is not enough.

The only truly perfect transmission is the AT transmission.

Many of our traditional car companies will also purchase AT transmissions from Aisin and ZF at high prices in order to enter the middle and high-end car market.

But even if it is, they are now equipped with this type of transmission in their car.

But when driving, the driver still can't feel the silky smoothness of a Japanese car equipped with the same transmission and a German car.

This is why?

And here, it involves the matching of the engine and the transmission.

The power output of your engine, the link to the transmission, the range of torque change, there is so much knowledge in it.

When to upshift and when to downshift, this is a test of the engineer's training skills.

And this is the unique skill of other German cars and Japanese cars, which is never easily spread out.

So even if you buy someone else’s gearbox, even if this gearbox is used by BMW and Lexus.

But after your engine is adapted, you simply can't drive other people's BMW power on call, feeling endless.

Not to mention Lexus's feeling of indulging in silky smoothness and speeding up silently.

This is the technical gap of matching training.

After all, people have accumulated at least 50 years of data and experience for their own engines and transmissions.

It is precisely because of the big data as before that people can grasp every subtle change between the engine and the transmission, and adjust their coordination to the best.

On the other hand, on our side, many car companies, even in the road test before leaving the factory, are reluctant to do too much.

The idea of ​​collecting big data has only emerged in the last ten years.

Many even entrust foreign companies to help. Just think about it. Will those foreign companies give you 100% of these key data?

As for the training, it will be more reserved.

After all, if all have taught you, whose business will they be going to do in the future?

So many foreign companies really rely on their previous technical bosses to make money lying down.

As for our domestic companies, companies like BYD and Great Wall will honestly run a road test of millions of kilometers before the car goes public.

To travel all over the Yangtze and Yellow Rivers, to the Qinghai-Tibet Plateau, I have to go to the Linhai Snow Plain, and then to the tropical rain forest.

It is relying on this kind of iron to collect data and technology. Of course, there is another car company, and that is FAW that everyone can't think of...

As for other car companies, what are the most beautiful Chinese cars, what Blue Whale power, and what foreign descent RW series are all shit.

Everyone knows it...

This is also the main reason why domestically-produced cars, regardless of the gimmicks, are very expensive every year, but traditional car companies want to talk about real technology, but there are still few major reasons for improvement.

In terms of power matching, our new Internet car-making forces have inherent advantages ~www.readwn.com~ You take the future, ideals, and Xiaopeng as the three car companies.

Among them, the future and Xiaopeng are engaged in pure electric vehicles, and the ideal is currently in the stage of extended-range electric vehicles.

In any case, their main vehicle is driven by electric motors.

And if it is driven by a motor, there is no power matching at all.

Because the difference between electric vehicles and fuel vehicles is here.

For a fuel car, you need an engine and a transmission.

However, electric vehicles or extended-range electric vehicles do not require a transmission.

Just rely on the motor to output power.

In this way, there is no need to consider the issue of power matching at all.

This is also the main reason why they can catch up from behind and make the car a high-end sense.

Because there is no power output matching, and the power output of the motor is faster and more fierce, it is easy to give people the feeling of driving a power monster.

In this way, as long as you do a good job of chassis tuning, the high-level sense of driving of this car will naturally come out.

You said that in the future, a professional team of European engineers was hired to help adjust the chassis of the first batch of cars.

Later, a research and development center was established in Germany to tune the chassis.

On the ideal side, it’s even more exaggerated. They set up their own chassis tuning team from the beginning.

And this team is not a joke, it's not just hire a few white Ding to fill up the count.

It just started to learn from the technology of the Mira team of the Great Yin Empire, and this team was split from the Saab brand of the year.

The test level of BMW X5 is 73KM/H, the test level of Mercedes-Benz GLC is 71.8KM/H, and the test result of Porsche Marken is 68.5KM/H...
