Luo Jia’s words aroused great interest from everyone, but not everyone can understand such things as blueprints. Boss Li knew that he didn’t read much, so he handed over the blueprints to BYD’s Boss Wang.
Boss Wang was born with a master’s degree in engineering. He worked in the Metallurgical Institute of the Chinese Academy of Sciences in his early years. He is a rare high-level 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 knew technology, and Great Wall’s boss Wei was in charge of sales, which is not bad. Each performs its duties, and the three swords combine.
As for the national team, Huaxia Automobile Group’s largest shareholder is Changan, and Changan belongs to the military’s General Armament Department, 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 gained great convenience. His entry and exit in 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 he did not hesitate to take Luo Jia to pay homage to the docks in various war zones at the age of almost eighty.
In just a few months, Luo Jia gained an unimaginably huge network 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 is done in secret, outsiders will never know.
Recently, hundreds of employees of Star Research Institute and Software Center have gone through the resignation procedures, and their destinations after resignation are the major research institutes of the military!
Luo Jia has already quietly dispatched the forces under his command to engage in electromagnetic guns!
Lin Zhiyu, the general manager of Huaxia Automobile Group, is one of the very few people who knows about this matter. 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 research and development level and fighting power.
This is called reciprocating. When major domestic automakers are generally trapped by foreign capital, it is the soldiers who guard the final bottom line. The sales volume of the Changan family is equal to SAIC plus GAC, plus FAW, plus Dongfeng.
Luo Jia saw all this clearly, so he decided to help the military keep the brand of Chang’an at all costs. The military’s technical strength is not high, so Xingchen Technology will take the top!
Eighty percent of the research and development work of the new generation of Changan Automobile is actually carried out in the laboratory of Star Technology, and the engineer team of Star Technology is directly stationed in the Chang’an factory to optimize the assembly line and production process.
In terms of strategy, it was also Luo Jia’s decision to let the East Asia Group go to the European market, and the Huaxia Group go to Southeast Asia, which is relatively less difficult.
This time, under the strong support of the military, all 17 million joint-venture production capacity were cut off, and the strong men lost their arms and suffered heavy losses.
In the final analysis, it should be due to the temper. The blood of the military and the masculinity of Xingchen Technology are in the same line, so in the end, Luo Jia and the national team always felt inseparable, but unconsciously, Getting closer and closer to the military.
How close is it?
When many people in the military talk about Luo Jia, they always feel that he and his group of tough guys are his own people, a group of old friends who can be trusted. Just call Luo Jia and ask Luo Jia if there is any way.
Things have developed to the present, the good thing is that Luo Jia finally has an extremely strong backing. In the future, when Luo Jia wants to flex his muscles, he will get the full support of the most **** people on the land of China.
The downside is that Luo Jia is not very free now. He has always wanted to see the high-tech industries in Germany, but now he has no chance at all. For safety, Comrade Luo Ning and his mother no longer travel abroad. domestic.
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 continued carefully.
He suddenly felt that the tough guy group was a bit annoying.
He has a straight-forward personality, and he doesn’t know how to write the introduction materials in an easy-to-understand manner. Boss Wang has a master’s degree in engineering, and he has worked in a big organization like the Chinese Academy of Sciences. I understand completely.
But when Boss Wang fully understood the gold content of this wheel hub motor, an irresistible impulse made his hands holding the blueprint tremble slightly, and his heart began to speed up. He almost wanted to express this with a loud roar. Excitement at the moment.
The hub motor is not a new technology. In the 1950s, an engineer named Robert in North America invented the hub motor. As early as 1968, General Motors produced a hub motor. dump truck.
The rear wheel of the electric bicycle that everyone is familiar with is driven by a DC hub motor with a power 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 clutches, transmissions, drive shafts, differentials and half shafts.
Abandoning all of these will result in an instant weight loss of several hundred kilograms.
Be aware that, mechanically, any drivetrain will result in power loss.
Because no transmission is required, hub motors are 8% to 15% more efficient than traditional motors, save a lot of space, reduce costs, and improve manufacturing efficiency.
According to calculations, if an electric car with a cost of 100,000 yuan is replaced with 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 the point of view of control, since the motor directly drives the wheels, the cu controller only needs to issue a simple command to change the speed and torque of the wheels, and the precision is very high, and complex manipulation can be easily realized .
Differential steering, which is difficult to achieve with traditional electric vehicles, can be achieved by using different rotation speeds of the left and right wheels, or even reverse rotation. The wheels are driven independently.
Finally, the hub motor can achieve more than 90% braking recovery, that is to say, when you step on the brake, the hub motor is actually in the state of generating electricity.
All in all, an electric vehicle using hub motors can be very light, has a large space, extremely flexible steering, and is very energy-efficient.
Huaxia has a Karman 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 hub motor has great advantages, but it also has some disadvantages, that is, it will increase the unsprung mass, it is difficult to be completely waterproof and dustproof, and the heat dissipation performance is not good, etc.
Especially the weight issue~Soverse.com~Ford and Schaeffler have jointly developed an in-wheel motor for the electric version of the Fiesta.
As a result, this wheel hub motor actually weighs 53 kilograms. It is like a person wearing a pair of heavy iron shoes, and of course it will be uncomfortable to walk.
Due to the heavy weight, Ford redesigned the high-strength suspension system for the electric carnival, which further increased the cost of the vehicle, resulting in the cost of the electric carnival being a full ten thousand dollars more than the gasoline version.
At this time, Boss Wang finally read the last page of the blueprint, and he shouted excitedly, “Solved! The three major defects of the hub motor have all been solved!”
“The power ratio of the new generation of hub motors has reached an astonishing 1.5:10!” 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, it only needs to install a motor weighing 7.5 kilograms on the two rear wheels to meet the power demand! This is really incredible! “
When everyone heard these words, they were stunned, and the expressions they showed were not surprise, but horror.
