Chapter 932 Continuously Variable Speed ​​Technology

Niu Xiaoqiang smiled and nodded: "In that case, I'll accept it. Although you prepared a gift for me, I didn't prepare one for you. I'm really sorry."

Zhang Xiaolan smiled and waved her hands: "You have given me so much help in the United States, and you have led me to earn so much extra money. Compared with the gifts I gave you, these are not much more expensive?"

Zhang Xiaolan only met Zhang Guangmao in the evening, and she never had a chance to talk to her father in detail, and she didn't even have time to send out the New Year's gift purchased from the United States.

When Zhang Guangmao heard this, he immediately asked curiously: "Xiaolan, how much money did Xiaoqiang earn with you?"

Zhang Xiaolan didn't hide anything, she explained the situation in detail, and finally said with a smile: "If Xiaoqiang hadn't taken me with me, I wouldn't even be able to pay back the debts, let alone have the money to buy gifts for you, all the gifts are stored by me in the guest house I'll give it to you tomorrow."

Feeling very relieved, Zhang Guangmao stretched out his hand and patted Zhang Xiaolan's shoulder: "Okay, very good, Xiaolan, you can follow Xiaoqiang from now on, and you will have a great future."

Zhang Xiaolan smiled sweetly, and looked at Niu Xiaoqiang: "Dad, you don't know, I am going to invest in a TV accessories factory in China, and I need Xiaoqiang's help in this matter. To be honest, I am already following him. "

This news made Zhang Guangmao even more happy. He couldn't close his mouth from ear to ear. He couldn't say anything except saying hello all the time.

After he was happy, Zhang Guangmao turned his head to look at Niu Xiaoqiang: "Xiaoqiang, uncle still has to be cheeky and beg you, please take care of Xiaolan, if she lives well in the future, even if I die as a father, I will die." I don't have any regrets."

Niu Xiaoqiang hurriedly waved his hand: "Uncle, what are you talking about? You can't talk nonsense when you celebrate the Chinese New Year. I will find someone to implement Xiaolan's matter, and I will guarantee that she will not lose money."

The three of them sat and chatted for about ten minutes, when Niu Qiuxiang's voice came from outside the door: "Little brother, Chen Fanghua and the others are here and say they want to talk to you about something."

Niu Xiaoqiang agreed, and smiled embarrassedly at Zhang Guangmao's father and daughter: "I only come back once half a year, there are too many things, I'm really sorry."

The two stood up tactfully, saying that they could continue their chat later when they had time.The three went downstairs together and saw Jiang Hongchang, Chen Fanghua and Li Xiaofeng in the living room on the first floor.

As soon as the three of them met, they nodded and greeted Niu Xiaoqiang repeatedly, with a very respectful attitude.

Niu Xiaoqiang looked at his watch, smiled wryly and said, "It's almost 10:30 now, why do you have to come to me so late?"

Jiang Hongchang scratched his head, "We came here to thank Secretary Niu for affirming us and allowing us to win the Excellent Employee Award, and secondly, we wanted to talk to you about new research and development projects."

Niu Xiaoqiang is not interested in the former, but is very interested in the latter.If this new technology is not very valuable, it is absolutely impossible for the three of them to come to find themselves in such a hurry.

He waved to the three of them: "Come on, let's go upstairs and talk."

Niu Xiaoqiang directly brought the three of them into the study room, made tea for the three of them respectively, and then sat down and asked, "Tell me, what new technology is it that makes you pay so much attention to it?"

This time it was Li Xiaofeng's turn to speak: "We call this technology continuously variable transmission technology."

Niu Xiaoqiang has heard about this technology: "Are you really capable of developing continuously variable transmission technology? How about this, please explain to me first, and I will see how your level is, and then discuss the development of things."

Li Xiaofeng smiled slightly and said: "Of course there is no problem. The continuously variable transmission technology uses the transmission belt and the driving and driven wheels with variable working diameters to cooperate with each other to transmit power."

The three of them obviously came prepared, Li Xiaofeng took out a piece of paper from his pocket, pointed to the simple diagram on it and said: "Look here, this is the simplified diagram we drew, as long as the gearbox is equipped with this The device can realize the continuous change of the transmission ratio, so that the transmission system and the engine can achieve the most perfect operation effect.”

The advantages of continuously variable transmission technology do not stop there. The biggest advantage is that it can reduce the frustration when shifting gears, and reduce shifting operations, so that the driver can have a better driving experience.

Of course, there are also disadvantages.The main reason is to increase the cost of maintenance.No matter what kind of equipment it is, the more complicated it is, the more likely it is to go wrong. If a continuously variable transmission technology is added to the car, it will increase the complexity and the cost of maintenance will also increase.

In addition, continuously variable transmission technology will also increase the fuel consumption of the vehicle.For a family car, since it is not used frequently and its displacement is relatively small, the increase in fuel consumption is still acceptable.But if it is a vehicle specially used for transportation, then the cost issue must be considered.

For example, the displacement of trucks is much larger than that of family cars, and the utilization rate is relatively high, so it is better not to use continuously variable transmission technology.

Niu Xiaoqiang looked at the drawings very carefully, and found that the three people's drawings looked good. He had a solid foundation in his mind, raised his head and said: "The sketches you drew are not bad. If you need anything, just ask it. , I will try my best to meet the conditions that can be given.”

The CVT technology is a new technology that Niu Xiaoqiang learned from Packard Motors. This technology is considered a relatively cutting-edge topic in the world, and there is no related research and development plan in China.

Sam is more thoughtful, and he is also very forward-looking, and he has been eyeing the continuously variable transmission technology early.It's a pity that after two or three years of tinkering, there is still no improvement.

The main reason is that Sam has no matching materials in his hand. Although he can design drawings that reach the practical application level, but the materials are not up to standard, and everything is useless.

Through trial and error, Sam found that the most critical link was the drive belt.

The transmission belt is the main part connecting the continuously variable transmission device and the engine drive shaft. Once the car is running normally, the transmission belt needs to withstand extremely high temperature and wear, and none of the existing materials can meet the design requirements.

If you use a soft material, such as a belt, it can only last for a short time, and the transmission effect is not very good, so it cannot be practically applied.

If the metal transmission belt is made of the same metal material as the gear, the effect will be even worse, and it will break at every turn, or it will need to be replaced frequently because it wears too fast, which will increase the maintenance cost, so the metal transmission belt cannot be used in practice. application.
