Luo Jia's words aroused great interest to 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 has a master's degree in engineering and worked in the Institute of Metallurgy of the Chinese Academy of Sciences in his early years. He is one of the few senior intellectuals among businessmen. He unfolds the blueprint and checks it carefully, and gradually frowns.

After the merger of the three major private automobile factories, Geely's Boss Li became the chairman of the board, BYD's Boss Wang was in charge of the Automobile Research Institute because of his knowledge of technology, while Great Wall's Boss Wei was very ruthless and was in charge of sales, which was considered to be his own duties, and the three swords combined.

In terms of the national team, the largest shareholder of Huaxia Automobile Group is Changan, which belongs to the General Equipment Department of the Military, so in fact, it is the military's power that controls Huaxia Automobile Group.

In this way, Luo Jia, who has a close relationship with the military, has achieved great convenience. He has entered and exited the Huaxia Automobile Group as convenient as entering and leaving his own territory.

The old general in the capital admired Luo Jia very much and took Luo Jia to various war zones to worship the wharfs at the age of almost 80.

In just a few months, Luo Jia has gained unimaginable connections in the military, from the research of electromagnetic guns to the design of new battleships, Xingchen Technology has participated in it.

Of course, all this was done in secret and outsiders would never know.

Recently, hundreds of employees from Star Research Institute and Software Center have completed the resignation procedures, and their whereabouts after their resignation are the major military research institutes!

Luo Jia has begun to send his power to build an electromagnetic cannon quietly!

Lin Zhiyu, general manager of Huaxia Automobile Group, is one of the few people who know this. He has always followed Luo Jia's advice, 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 rewarding. When major domestic automobile manufacturers generally fell into overseas capital, soldiers defended the final bottom line. Changan's sales volume is equivalent to SAIC-GAC, FAW, and Dongfeng.

Luo Jia clearly saw all this, so he decided to help the military defend the Chang'an brand at any cost. The military's technical strength is not high, so it will be topped by Xingchen Technology!

Eighty percent of the research and development of the new generation of Changan Automobile was actually carried out in the laboratory of Xingchen Technology, and the engineer team of Xingchen Technology directly entered the Changan factory to optimize the assembly line and production process.

In terms of strategy, letting East Asia Group fight against the European market, and Huaxia Group's relatively difficult move to Southeast Asia was also Luo Jia's decision.

This time, under the military's strong leadership, all 17 million combined assets could be cut off, and the hero cut off his arms and suffered heavy losses. It is really tragic and it needs to give them an easy environment to develop and restore their vitality.

After all, it should be the reason for turning a temper. The military's bloodiness and the masculinity of Xingchen Technology are in line with each other, so in the end, Luo Jia and the national team always felt a sense of being close and distant, but they were getting closer and closer to the military without realizing it.

How close is it?

When many people in the military talk about Luo Jia, they always feel that he and his tough guy group are their own people and a group of trustworthy old friends. When some R&D tasks are not done, they are not polite and call Luo Jia directly and ask if there is any solution.

The advantage of the matter being developed to this point is that Luo Jia finally has an extremely powerful support. When Luo Jia wants to show her strength in the future, she will receive strong support from the most bloody group of people on the land of China.

The downside is that Luo Jia is not very free now. He has always wanted to see Germany's high-end and sophisticated industries, but now he has no chance. For safety, Comrade Luo Ning and his mother no longer travel abroad and have been in China.

This is probably another example that everything has a price.

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 group was a little annoying.

With a straightforward personality, I don’t know how to write the introduction materials easily and easily understood. Boss Wang has a master's degree in engineering and has worked in a big institution like the Chinese Academy of Sciences. It’s so difficult to read it. After reading it for a long time, I couldn’t fully understand it.

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

Hub motors are not new technology. In the 1950s, an engineer named Robert from North America invented the hub motor. As early as 1968, General Motors produced dump trucks with hub motors as the driving force.

The rear wheels of the electric bicycles that are familiar to everyone are driven by DC hub motors, with a power of between 300w and 1500w, and the price is very low, only one or two hundred yuan.

Compared with traditional motor drives, hub motors have a huge advantage, that is, they completely abandon the transmission system.

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

Abandoning all of these will cause the vehicle to lose hundreds of kilograms in an instant.

You should know that according to mechanical principles, any transmission system will cause power loss.

Because there is no need for transmission, the efficiency of the hub motor is 8% to 15% higher than that of traditional motors, and saves a lot of space, reduces costs, and improves manufacturing efficiency.

According to calculations, if an electric car with a cost of 100,000 yuan is switched to a hub 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 the perspective of control, since the motor directly drives the wheels, the mcu controller only needs to issue a simple command to change the speed and torque of the wheels, and the accuracy is very high, so complex manipulation can be easily achieved.

Differential steering that is difficult to achieve by rotating the left and right wheels can be achieved through different speeds or even reverse rotations of the left and right wheels. The steering radius of the vehicle can be reduced, and even 360 degrees of in-situ steering can be achieved, so as to achieve true four-wheel independent driving.

Finally, the hub motor can achieve more than 90% brake recovery, which means that when you step on the brake, the hub motor is actually in a power generation state.

In short, electric cars with hub motors can be very light, have a lot of space, extremely flexible steering, and are very energy-efficient.

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

Of course, hub motors have high advantages, but there are also some disadvantages, that is, they will increase the quality of the unsprung, make it difficult to be completely waterproof and dustproof, poor heat dissipation performance, etc.

Especially for the weight issue, Ford and Schaeffler jointly developed a hub motor installed on the electric version of the Carnival.

As a result, this kind of hub motor weighs 53 kilograms. It's like a person wearing a pair of heavy iron shoes, of course he feels uncomfortable when walking.

Due to the heavy weight, Ford redesigned a high-strength suspension system for the electric carnival, further increasing the cost of the vehicle, resulting in the cost of the electric carnival being 10,000 US dollars more than the gasoline version.

At this time, Boss Wang finally finished reading the last page of the blueprint. He shouted excitedly: "It has been solved! All three defects of the hub motor have been solved!"

"The power proportion of the new generation of hub motors has reached an astonishing 1.5 to 10!" Boss Wang exclaimed, "A hub motor weighing 15 kilograms can provide a power output of 100 kilowatts!"

"Taking a small electric car with a power of 100 kilowatts and two-wheel drive as an example, you only need to install a 7.5 kilogram motor on each of the two rear wheels to meet the power needs! This is incredible!"
Chapter completed!
