Automotive Black Technology Chapter 589: : The strongest power, perfect axle load ratio! (10,000 rewards plus 1 more)

www.lnmao.org, the fastest update to the latest chapter of automotive black technology!

Little Kurt followed Li Fanyu's ideas, went through some hydrochloric acid, and straightened out the power layout again.

The more he looked at the thick stack of data on his desk, the more he felt that this layout was a stroke of genius and a gift from God!

With this excitement, he immediately used Li Fanyu's sketch as a blueprint and led the R&D engineers to immediately invest in research and development.

Both the engine and the layout needed to be worked on, so Culbot Jr. divided the engineering team into two groups.

The engine part is led by myself, while the body layout, transmission structure and rear transmission differential reducer are handed over to the initiator of the concept, Li Fanyu, who is familiar with cars.

The sketch Li Fanyu gave to Little Culbo has clearly defined the structure and various parameters of the Cadillac V16 codenamed "Kuafu".

So the research and development work of the first team was quite smooth. Taking advantage of Detroit's complete research and development supporting industries, the research and development process of Kuafu V16 is proceeding at a rapid pace.

And Li Fanyu is not slow here either!

It took less than a week to use the calculation computer to finalize the body proportions and weight ratio. After some simulations using the database, the team delineated various dimensions of the chassis very quickly.

As for the seven-speed dual-clutch structure of the rear-mounted version, it took Li Fanyu a week to complete it.

Since then, the two teams have quickly connected. The Kuafu V16, which was initially trial-produced, is matched with the completely new RS chassis. In the first test, the new design showed a very shocking effect;

The Kuafu V16 engine trial version has been made vague in many aspects for the sake of speed. Some processes were not done strictly in accordance with Li Fanyu's requirements.

But even so, in the first test, a set of data that was so awesome that it flew into the sky!

This engine, which was built purely for testing, has a maximum horsepower of 730KW! Nearly 1,000 horses! The power data may not seem like much at first glance, but the torque of 1330NM can be described as crazy!

Seeing that the overall operation of the engine was normal and that the structure passed the test, Li Fanyu immediately asked Kuerbo to start trial production of one. And the electronic turbocharger was sent from China and transplanted to the carefully made Kuafu V16!

In this way, the data of this engine is so strong that it has no friends.

The power of 1015KW, the torque of 1655NM, and the displacement of 14 liters have steadily surpassed the Aventador V16 on Punms in terms of data!

However, when this engine was combined with a new prototype prototype and tested on a bench, various data on the new RS body were obtained.

Little Culbo's admiration for his young boss is like a torrential river...

Strong,

Just don’t be too strong!

In the previous view of Little Culbo, the layout structure of RS's new engine and gearbox separated at the front and rear is just a solution made by Li Fanyu to overcome the V16 engine taking up too much space in the engine compartment and to counterbalance the weight. sexual design.

But it turns out that this new layout design is far more outstanding than he imagined!

What is outstanding?

Here, it is related to an issue of axle load ratio,

The so-called axle load ratio is the ratio of the front and rear axles sharing the weight of the vehicle. Generally speaking, the front and rear axle load ratio of 50:50 is the best; this axle load distribution ratio is conducive to even tire wear and ensures that the car has better cornering characteristics and driving stability.

However, the engine layout plays an important role in balancing the axle load distribution.

The power layout of automobiles can be roughly divided into three types - front, mid and rear.

Not to mention the front engine, this is the most common arrangement and is used by the vast majority of vehicles on the market.

For front-mounted engines, it is generally necessary to reduce the front axle load.

Front-mounted engines are divided into two types: transverse arrangement and longitudinal arrangement. In order to improve the utilization of the engine compartment and increase the driving space, most models have adopted the transverse engine arrangement.

In addition, transversely mounting the engine is also conducive to the layout of the transmission and simplifies the structure of the main reducer. But the same thing - a transverse engine is very detrimental to reducing the front axle load.

So in order to achieve reasonable axle load distribution, it is very necessary to install the engine longitudinally.

This is already reflected in the new layout of RS! The Kuafu V16 is installed vertically in the engine compartment.

However, with a conventional front longitudinal engine and rear-wheel drive, it is difficult to achieve a perfect axle-load ratio.

So some models that want to achieve results in performance and control choose a front-rear-drive layout and longitudinally-mounted engines. When paired with rear-wheel drive, the axle load distribution is one step closer to perfection.

Rear drive means placing the final drive and differential at the back, both of which are relatively heavy!

There are many models with front longitudinal engines and rear-wheel drive, but we have not seen how ideal their axle loads are.

Why?

There is only one truth; because these efforts are still difficult to achieve the ideal distribution requirements!

So, the chicken shooters came up with a solution - rear-mounted engine, which is the legendary rear-mounted rear drive.

But the problem comes again, that will make the rear axle load too heavy.

So the clever chicken shooters came up with another idea - mid-engine and rear-mid engine.

In this way, the axle-load ratio is balanced. Therefore, generally high-performance sports cars adopt this layout method, such as Punms.

But Li Fanyu used a simple and crude method of rear-mounted transmission to achieve a perfect 50:50 axle-load ratio of the RS!

In fact, just over two weeks ago, OEM R&D engineers complained when they saw the layout where the engine was in the front and the transmission was moved to the back, and the driver and passengers were sandwiched between the engine and transmission. This is a crazy approach

You can see with your own eyes that the design is put into practice step by step. With the transmission, main reducer and differential placed on the rear axle according to a very scientific layout.

Watching Li Fanyu stubbornly shorten the length of the front overhang, watching him lengthen the length of the front engine compartment, so that the center of gravity of the engine falls behind the front axle...

Every step is a big step towards RS perfection.

After doing all these things, a sports car with the most powerful power and perfect axle load distribution in the world was born!

At this time, the RS in front of everyone is already a SuperCar that they can look up to!
