Chapter 254: All 3 major defects are solved!

Luo Jia's words aroused great interest from everyone, but not everyone could understand the blueprint. Boss Li knew that he didn't read much, so he gave the blueprint to BYD's boss Wang.
Boss Wang was born with a master's degree in engineering. He worked in the Institute of Metallurgy of the Chinese Academy of Sciences in his early years. He is a rare senior intellectual among businessmen. He unfolded the blueprint, looked closely, and gradually frowned.
After the merger of the three major private car factories, Geely ’s boss Li became chairman of the board of directors. BYD ’s boss Wang is in charge of the Automotive Research Institute because he knows the technology, while Great Wall ’s boss Wei has a strong stock and is in charge of sales. Position, three swords combined.
As for the national team, the largest shareholder of Huaxia Automobile Group is Chang'an, and Changan belongs to the General Armament Department of the military. In fact, it is the military's power that controls the Huaxia Automobile Group.
In this way, Luo Jia, who has close relations with the military, has achieved great convenience. His entry and exit at Huaxia Automobile Group is as convenient as entering and leaving his own place.
The old general in Beijing greatly appreciated Luo Jia, and at the age of 80, he took Luo Jia personally to visit the docks in various theaters.
In just a few months, Luo Jia was in the military and obtained huge unimaginable connections. From the research of electromagnetic guns to the design of new battleships, Star Technology has participated in it.
Of course, all this is done in secret, and outsiders will never know.
In the recent period, hundreds of employees of the Star Research Institute and Software Center have completed the resignation procedures, and their whereabouts after leaving are precisely the major military research institutes!
Luo Jia has begun to send his force to quietly send electromagnetic guns!
Lin Zhiyu, the general manager of Huaxia Automobile Group, is one of the very few people who understands this matter. His suggestions to Luo Jia have always been obedient. Luo Jia also sent the power of Xingchen Technology to help Huaxia Automobile Group to improve its research and development level and combat effectiveness.
This is called touting Taobao Li. When major domestic automobile manufacturers were generally trapped in foreign capital, the soldiers kept the final bottom line. The sales of the Changan family equaled SAIC, GAC, FAW, and Dongfeng.
Luo Jia saw all this clearly, so he decided to help the military keep the brand of Chang'an at any cost. The military's technical strength is not high, so it is topped by Xingchen Technology!
Eighty percent of the research and development 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 directly enters the Changan factory to optimize the assembly line and production process.
In terms of strategy, it was Luo Jia's decision to let the East Asian Group go to the European market and Huaxia Group's expedition to Southeast Asia with relatively low difficulty.
This time under the leadership of the military, all 17 million joint-venture production capacity were cut off, the strong men broke their arms, and suffered heavy losses. It was really tragic enough, and they needed to give them an environment for easy development and restore vitality.
After all, it should be the reason for the temper. The blood 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 felt a sense of being away, but unknowingly, and the military Walking closer and closer.
How close is it?
When many people in the military talked about Luo Jia, they always felt that he and his tough guy sky group were their own and a group of trusted old friends. When some R & D tasks were unsuccessful, they were not polite and gave Luo directly Jia called and asked Luo Jia if there was any way.
The thing is that now, the good thing is that Luo Jia finally has an extremely powerful backup. When Luo Jia wants to show his strength in the future, he will get the full support of the most people on the Chinese land.
The disadvantage is that Luo Jia is not very free now. He has always wanted to see the high-tech industries in Germany. Now he has no chance at all. For safety, Comrade Luo Ning and his mother no longer travel abroad and change to China.
This is probably another example of the cost of everything.
Boss Wang took off his glasses, wiped the corners of his eyes with a napkin, and then proceeded carefully.
He suddenly felt that the tough guy sky group was a bit annoying.
I have a straight personality, and I do n’t know the easy to understand introduction of the introduction. The master of engineering, Wang Botang, has worked in a large institution such as the Chinese Academy of Sciences, and it has been so difficult to read it. .
But when Mr. Wang thoroughly understood that after the gold content of this in-wheel motor, an irresistible urge made his hands holding the blueprint tremble slightly, and his heart began to accelerate. He just wanted to use a loud roar to express the excitement at this moment. Emotions.
In-wheel motors are nothing new. In the 1950s, an engineer named Robert in North America invented the in-wheel motors. As early as 1968, General Motors produced dump trucks with in-wheel motors as the driving force. .
Everyone is familiar with the electric bicycle, the rear wheel is driven by a DC hub motor, the power is between 300w and 1500w, the price is also very low, only one or two hundred yuan.
Compared to traditional motor drives, in-wheel motors have a huge advantage in that they completely abandon the drive system.
A complete transmission system is composed of clutch, transmission, drive shaft, differential and half shaft.
Abandoning all of these will cause the vehicle to lose hundreds of kilograms instantly.
Be aware that, based on mechanical principles, any transmission system causes power loss.
Because no transmission is required, in-wheel motors have 8% to 15% higher efficiency than traditional motors, and save a lot of space, reduce costs, and improve 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 the control point of view, 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 it can easily achieve complex manipulation.
Differential speeds of the left and right wheels, or even reverse rotation, can be used to achieve differential steering that is difficult to achieve by traditional electric vehicles. The turning radius of the vehicle can be reduced, and even 360 degrees of in-steering can be achieved. Real independent four-wheel drive .
Finally, the in-wheel motor can achieve more than 90% of the brake recovery, that is, when you step on the brake, the in-wheel motor is actually in the state of power generation.
All in all, electric vehicles using in-wheel motors can be very light, have a lot of space, have extremely flexible steering, and are very energy efficient.
Huaxia has Carmen Vortex Street Power 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 high advantages, but it also has some disadvantages, which is that it will increase the unsprung mass, it is difficult to achieve complete waterproof and dustproof, and poor heat dissipation performance.
Especially with regard to weight, UU reading www.uukanshu.com Ford and Schaeffler have jointly developed a wheel motor that is mounted on the electric version of the carnival.
As a result, this in-wheel motor weighs 53 kilograms, which 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, further increasing the cost of the entire vehicle, which caused the cost of the electric carnival to be a full $ 10,000 more than the gasoline version.
At this time, boss Wang finally read the last page of the blueprint, he shouted excitedly, "Solved! All three major defects of the wheel motor have been solved!"
"The power proportion of the new-generation in-wheel motor has reached an astonishing 1.5 to 10!" Boss Wang exclaimed. "A wheel motor with a weight of 15 kg can provide a hundred kilowatts of power output!"
"Taking a small electric car with a power of 100 kilowatts and two wheels as an example, you only need to install a motor with a weight of 7.5 kilograms on each of the two rear wheels to meet the power demand! This is incredible!"
When everyone heard these words, they were suddenly stunned, and the expressions were not surprised, but frightened.
