Luo Jia's words aroused great interest from everyone, but not everyone can understand the blueprint, Boss Li knew that he didn't read much, so he handed over the blueprint to BYD's Boss Wang.

Boss Wang was born with a master's degree in engineering, worked in the Institute of Metallurgy of the Chinese Academy of Sciences in his early years, and was a rare senior intellectual among businessmen.

After the merger of the three major private automobile factories, Geely's Boss Li became the chairman of the board of directors, BYD's Boss Wang was in charge of the Automobile Research Institute because he understood technology, and Boss Wei of the Great Wall was ruthless and in charge of sales.

In terms of the national team, the largest shareholder of Huaxia Automobile Group is Changan, and Changan belongs to the General Armament Department of the military, so in fact, it is the military that controls Huaxia Automobile Group.

In this way, Luo Jia, who has a close relationship with the military, has achieved great convenience, and his entry and exit in and out of Huaxia Automobile Group is as convenient as entering and exiting his own territory.

The old general in the capital admired Luo Jia very much, and did not hesitate to take Luo Jia to various war zones to worship the docks at the age of almost eighty.

In just a few months, Luo Jia has gained unimaginable huge contacts in the military, from the research of electromagnetic guns to the design of new battleships, Xingchen Technology has been involved.

Of course, all this is done in secret, and outsiders will never know.

Recently, hundreds of employees of the Xingchen Research Institute and the Software Center have gone through the resignation procedures, and their whereabouts after leaving are the major military research institutes!

Luo Jia has already begun to quietly send the forces under his command to engage in electromagnetic cannons!

Lin Zhiyu, the general manager of Huaxia Automobile Group, is one of the very few people who understand this matter, and he has always listened to Luo Jia's suggestions, and Luo Jia also sent the power of Xingchen Technology to help Huaxia Automobile Group improve its R&D level and combat effectiveness.

This is called repaying the peach, when the major domestic automobile manufacturers generally fell into foreign capital, it was the soldiers who kept the final bottom line, and the sales volume of the Chang'an family was equal to SAIC plus GAC, FAW, plus Dongfeng.

Luo Jia clearly saw all this, so he decided to help the military keep the brand of Chang'an at any cost, the military's technical strength is not high, then Xingchen Technology will top!

Eighty percent of the R&D work of the new generation of Changan Automobile is actually carried out in the laboratory of Xingchen Technology, and the engineering team of Xingchen Technology is directly stationed in the Changan factory to optimize the assembly line and production process.

In terms of strategy, it is also Luo Jia's decision to let the East Asia Group go to the European market and the Huaxia Group to go to Southeast Asia, which is relatively difficult.

This time, under the leadership of the military, the production capacity of 17 million vehicles of the joint venture has been cut, and the strong man has broken his arm and suffered heavy losses.

In the final analysis, it should be the reason for the temper, the bloodiness of the military and the masculinity of Xingchen Technology are in the same vein, so in the end, Luo Jia and the national team always have a feeling of being separated, but unconsciously, they are getting closer and closer to the military.

How close?

When many people in the military talk about Luo Jia, they always feel that he and his tough guy Tiantuan are their own people, a group of trusted old friends, and when some research and development tasks can't be completed, they are not polite, and they call Luo Jia directly and ask Luo Jia if there is a way.

Things have developed so far, the good thing is that Luo Jia finally has an incomparably strong backup, and when Luo Jia wants to show his strength in the future, he will get the full support of the most bloody group of people in the land of China.

And the disadvantage is that Luo Jia is not very free now, he has always wanted to see the high-tech industry in Germany, and now there is no chance at all, for safety, Comrade Luo Ning and his mother no longer travel abroad, but in China.

This is probably another example of how everything comes at a cost.

Boss Wang took off his glasses, wiped the corners of his eyes with a napkin, and then continued to read carefully.

He suddenly felt that the tough guy Tiantuan was a little annoying.

Straightforward character, I don't know how to write the introduction information is easy to understand, Boss Wang's dignified master's degree in engineering, and he has worked in a big institution like the Chinese Academy of Sciences, and he has been so difficult to read it, and he didn't fully understand it after reading it for a long time.

But when Boss Wang thoroughly understood the gold content of this hub motor, an irrepressible impulse made his hands holding the blueprint tremble slightly, and his heart began to accelerate, and he almost wanted to use a loud roar to express his excitement at this moment.

In-wheel motor is not a new technology, in the fifties of the 20th century, an engineer named Robert in North America invented the in-wheel motor, and as early as 1968, General Motors produced a dump truck with in-wheel motor as the driving force.

The familiar electric bicycle, its rear wheel is driven by a DC hub motor, the power is between 300 and 1500, and the price is also very low, only one or two hundred yuan.

One of the great advantages of in-wheel motors over conventional motor drives is that the drivetrain is completely abandoned.

A complete transmission system, consisting of a clutch, transmission, transmission shaft, differential and half shaft.

Throwing all of this away will result in a few hundred kilograms of weight loss in the vehicle.

It is important to know that, according to mechanical principles, any drivetrain will result in power loss.

Because there is no need for transmission, the in-wheel motor is 8 to 15 percent more efficient than the traditional motor, and saves a lot of space, reduces costs, and improves manufacturing efficiency.

According to calculations, if an electric vehicle with a cost of 100,000 yuan is switched to an in-wheel motor, the cost will be reduced by 15,000 yuan, and the average daily output of each production line can be increased by 20%.

From a control point of view, since the motor directly drives the wheels, the MCU controller can change the speed and torque of the wheels with a simple command, and the accuracy is very high, and complex maneuvers can be easily realized.

Through the different speeds of the left and right wheels, or even reverse rotation, differential steering can be achieved that is difficult to achieve by traditional electric vehicles, the steering radius of the vehicle can be reduced, and even 360 degrees of in-situ steering can be realized, so as to achieve real four-wheel independent drive.

Finally, the in-wheel motor can achieve more than 90% braking recovery, that is, when you step on the brake, the in-wheel motor is actually in a state of power generation.

All in all, an electric vehicle with an in-wheel motor can be very light, has a lot of space, is extremely flexible in steering, and is very energy-efficient.

Huaxia has a Carmen vortex street power generation array, which is about to realize power freedom, but foreign power may not be sufficient, so the advantage of energy saving is still very attractive to foreign users.

Of course, the in-wheel motor has high superiority, but it also has some disadvantages, that is, it will increase the unsprung mass, it is difficult to achieve complete waterproof and dustproof, poor heat dissipation performance and so on.

In particular, on the issue of weight, Ford and Schaeffler jointly developed an in-wheel motor that could be mounted on an electric version of the Fiesta.

As a result, this kind of hub motor weighs 53 kilograms, which is like a person wearing a pair of heavy iron shoes, of course, walking will be uncomfortable.

Due to the large weight, Ford redesigned the high-strength suspension system for the electric Fiesta, further increasing the cost of the whole vehicle, resulting in the cost of the electric Fiesta being a full $10,000 more than the gasoline version.

At this time, Boss Wang finally finished reading the last page of the blueprint, and he shouted excitedly: "It's solved!" The three major defects of the in-wheel motor have all been solved! ”

"The power ratio of the new generation of in-wheel motors has reached an astonishing 15 to 10!" Boss Wang exclaimed, "A hub motor weighing 15 kilograms can provide a power output of 100 kilowatts!" ”

"Take a small electric vehicle with a power of 100 kilowatts and two-wheel drive as an example, only two rear wheels and a motor weighing 7.5 kg need to be installed to meet the power demand! It's incredible! ”

When everyone heard this, they were stunned, and their expressions were not surprised, but frightened.
