New Year's Day.

"Brother Shaoyou, it's rare to have a holiday today. I have to continue research and development with sister Mengyao. I still have a lot of ideas." Xia Miaomiao complained to Qin Shaoyou on the Qin SUV.

"Miaomiao, it's finally time for vacation, so let's go back and see your parents." Qin Shaoyou said, "Going back and forth within the day will only waste your day."

"Brother Shaoyou, do you know how tight time is? Every second is precious."

"Yeah, so, you work in the car." Qin Shaoyou said.

Xia Miaomiao curiously took over a thick briefcase that Qin Shaoyou handed her, opened it, and suddenly her eyes lit up: "Notebook?"

Xia Miaomiao opened the lid with one hand, and looked at the LCD screen on it, almost drooling.On the keyboard, that red towel is so clear.

&n, the words thinkpad700c are printed on the lower left corner.
The machine is pre-installed with Microsoft's Windows 3.1 system, so you can enter the graphical interface when you turn it on. Qin Shaoyou has pre-installed programming software in it, and Xia Miaomiao can work even in the car.

With the sound of starting up, the blue sky and white clouds logo appeared on the screen, Xia Miaomiao excitedly said to Qin Shaoyou: "Brother Shaoyou, this is a lot of money, right?"

"Well, four thousand three hundred and fifty dollars." Qin Shaoyou said.

Xia Miaomiao was shocked and almost dropped the notebook.

"So expensive?"

"Of course, this is the highest-performance notebook currently on sale. I asked people from General Motors to buy it for me from the United States." Qin Shaoyou said, "Hurry up and work. The only disadvantage of it is the short standby time. Ni-MH batteries can only provide four hours of battery life, it seems that I should add a 220-volt power supply to the car."

At this time, Qin Shaoyou was still driving Mercedes-Benz, and at the same time he was thinking about the development of the car. It is not appropriate to only get electricity from the cigarette lighter. It would be even better for passengers to use electronic products in the car. Although mobile phones have not yet developed, notebooks will soon fall into the hands of high-end people.

Xia Miaomiao stabilized her mind and started to tinker. Qin Shaoyou continued to drive and soon came to Guangming Motorcycle Factory.

Qin Shaoyou will never forget the scene of coming here for the first time, and now, when he comes here again, the outside of Guangming Motorcycle Factory is still lively and lively.

A three-wheeled motorcycle drove over from inside. This kind of car was completely designed according to Qin Shaoyou's design. The front of the car was a 125 motorcycle, and the back was a carriage. However, at the end of the carriage at this time, there was still a The front wheel of the first three-wheeled motorcycle, the second three-wheeled motorcycle, is driving like this, and behind it is the front wheel of the third three-wheeled motorcycle, just like this, one next to the other. , there are more than a dozen of them, forming a three-wheeled train.

Qin Shaoyou was amazed, it seems that the sales of these three-wheeled motorcycles are booming!

"Qin Gong is here!" The old man at the door saw Qin Shaoyou, and immediately greeted Qin Shaoyou enthusiastically.

"Uncle, is the factory going to work today?"

"Come on, the factory manager and the others are all inside!"

Qin Shaoyou nodded, drove into the factory, and stopped directly at the door of the R&D workshop.

Glancing at Xia Miaomiao who was working on the seat, Qin Shaoyou pushed the car door and went down by himself.

In the R&D workshop, a group of people are discussing.

"Our motorcycles don't need to be in reverse gear. After all, the car is not big. When you need to reverse the car, just push it down." A technician said: "On the contrary, it is the transmission method. The chain transmission is too backward. We It would be great if it could be improved into a drive shaft."

"This is inconvenient. As for the drive shaft, does the engine have to be turned sideways? Then everything has to be changed, which is too wasteful!"

"If we need to change, we have to change. Our Guangming Motorcycle is the leader in this industry. If we don't engage in technological innovation, we will be caught up by others."

Listening to these people's lively discussions, Qin Shaoyou was very happy. They, a small motorcycle factory, can take technological innovation as their duty.

"I have an easy way." Someone said again.

"what way?"

"We can reverse the engine! In this way, putting forward gear is reverse gear!"

All engines without an electronic control system have this feature. Whether it is a gasoline engine or a diesel engine, they can not only rotate forward, but also reverse.

However, turning it backwards is not a normal operation. The intake air is taken from the exhaust pipe, and the dirt in the exhaust pipe is sucked into the engine, and the air filter is also dirty from the air intake port. This technology How weird the thinking of the personnel must be to come up with this method?

"Haha." Qin Shaoyou couldn't help laughing.

Hearing Qin Shaoyou's laughter, everyone turned their heads, and then everyone was overjoyed.

"Qin Gong!"

"Qin Gong!"

"You are here, Shaoyou." Xia Tiannan looked at Qin Shaoyou in surprise and said to him.

"Well, today's National Day, I'll bring Miao Miao back to have a look."

"Where's Miao Miao? Her mother misses her." Xia Tiannan said.

Xia Miaomiao's mother, Luo Ying, once accepted Qin Shaoyou's suggestion and went to Huating to open a motorcycle specialty store. However, after the Guangming Motorcycle brand was launched, many agents came to the door to buy, so Luo Ying also I didn't need to sell motorcycles at Huating, so I came back.

After that, it was not easy to see Xia Miaomiao.

Xia Nan said while looking at the door where Qin Shaoyou came in.

"It's in the car outside, Miao Miao is still working." Qin Shaoyou said, "Let Muma go to the car to meet her."

Xia Nan nodded, and asked Luo Ying to report the letter. Then, Xia Nan continued to look at Qin Shaoyou: "Shaoyou, you can solve these problems for us!"

Qin Shaoyou nodded: "The reverse gear and the transmission shaft must be solved together."

For Qin Shaoyou, it is not easy to improve a motorcycle. He squatted down and pointed to the gear shifting mechanism of the motorcycle: "Here, remove the pinion gear and replace it with a conical wheel, and rotate the power ninety degrees. It's over."

It is too simple to change the direction of power transmission.

"At the same time, directly use this conical wheel to make a positive and negative commutator. Behind the commutator, a cross shaft is connected, and then the transmission shaft passes to the rear axle."

There are many problems with the chain drive. The chain exposed to the outside will be damaged in one or two years. If you don't go up and roll the car, the engine will not be able to provide braking force in time.

Therefore, after the three-wheeled motorcycle develops to a certain stage, it will transition from chain drive to shaft drive.

Qin Shaoyou said that these conical wheels are easy to understand, but what about this commutator?

Everyone was a little curious, so Qin Shaoyou made a few gear gestures.

These devices Qin Shaoyou talked about are all fixed together and installed behind the original gear mechanism. There are three bevel gears inside, and the driving wheel is connected to the side of the engine shift mechanism. The driven wheel, which is splined on the output shaft, can be moved axially.

Looking from the back to the front, the driving gear rotates clockwise. When it meshes with the left bevel gear, the driven shaft rotates forward; when it meshes with the right bevel gear, the driven shaft rotates reversely. One of the driven wheels meshes with the driving wheel to achieve the forward and reverse effect of the output shaft.

It is different from the gearbox of a car. There is only one reverse gear in a car gearbox. It is more like an auxiliary gearbox that can change the direction of power output. At the same time, it must be operated in conjunction with the previous gear. If you are skilled, you can even Use the highest gear to drive to achieve a reverse speed of [-] kilometers per hour, which is exactly the same speed as driving forward.

These technicians pondered for a long time, and it was impossible to add a reverse gear to the original gear, but Qin Shaoyou's modification made it easy.

It can not only reverse the car, but also install the transmission shaft. The rear axle can be converted into an integrated rear axle. It can be reduced according to the ratio of the car drive axle. This is very simple.

"Qin Gong, you are so amazing!" After seeing Qin Shaoyou's design, everyone couldn't help but sigh with emotion.

"The principle is very simple, and it is easy to imitate. Therefore, we must keep it secret now, and register this equipment as a patent. If any motorcycle company wants to use it, you can buy the patent. If we copy ours, we will file a lawsuit with them." Qin Shaoyou said.

Xia Nan nodded: "Well, the patent right is yours, don't worry, we will protect it for you, if someone dares to copy it, we will sue him to lose his pants!"

There is nothing wrong with the ownership of the patent right, it was designed by Qin Shaoyou, and Xia Nan wants to protect it for his future son-in-law.

Qin Shaoyou nodded, and Xia Nan and the others went to toss about it casually. For Qin Shaoyou, these were trivial matters. He wanted to make Guangming Motorcycle develop better, overwhelm the crowd, and become the leader in the motorcycle industry.

He really doesn't like this kind of sesame mung bean.

"Stop traveling. Last year, our Guangming Motorcycle launched a tricycle, and the sales volume has increased to a higher level. Moreover, it has become the most fashionable means of transportation in the countryside. Tell me, can our car continue to be improved?"

Xia Nan's gaze was full of anticipation.

"Of course it can." Qin Shaoyou came here to visit relatives, in fact, he had the idea of ​​giving some pointers by the way. He looked at the sample car on the scene: "At present, the power of the 125 engine is not strong enough, so we can expand the cylinder later. to 150."

"150?"

"That's right, after the expansion of the cylinder, the air cooling is changed to water cooling, and a cooling water tank is added in the front, which can facilitate heavy loads. Then, the whole body is strengthened, and the number of rear tires becomes four."

"What?"

Everyone was extremely surprised. Is Qin Shaoyou going to turn their three-wheeled motorcycle into a five-wheeled motorcycle?

"In this way, our motorcycle can hold a ton of cargo, which is more than a van, and it can become a good helper for farmers to get rich." Qin Shaoyou said.

Isn't it normal for a tricycle to become a five-wheeler?Anyway, the country doesn't care about it now, this is still a legal gap, take advantage of this opportunity, and provide farmers with an outstanding travel tool!

"Well, Shaoyou, what you said is good. It can be an upgraded model that we will focus on launching next year. However, do you think it is possible for us to develop into passenger cars?" Xia Nan continued.

Qin Shaoyou glanced at his father-in-law curiously: "Passenger car?"

Sure enough, anyone who builds motorcycles wants to build cars.

"En." Xia Nan nodded again and again.

"Then do you want to take it step by step, or do you want to become fat with one bite?"

"Of course, step by step." Xia Tiannan said.

"In this case, I have an idea, let's build the old man with three rounds first."

"Old man music?"

Everyone didn't know what this meant, but Qin Shaoyou quickly picked up the paper and pen and started drawing aside.

"The chassis of the current three-wheeled motorcycle is still used, but the appearance needs to be greatly changed. Let's have a QQ version of the old man first." Qin Shaoyou said while drawing. His drawing skills are very good, and soon Just buckle the qq shell on the three-wheeled chassis.

"The driving method should be changed to a steering wheel. In this way, there are doors at the front and rear, and it is no problem for four people to sit in it." Qin Shaoyou said: "When the sales are good in the future, then change to a four-wheeled one, gradually upgrade, little by little. Come on, move the accelerator and brake, and change the gear to manual."

Although most of Old Tou Le is electric, before the popularity of electric, there is still a motorcycle engine version, and even more powerful, it is a hybrid of motorcycle and electric together.

"However, if this is the case, it is equivalent to a major facelift." Qin Shaoyou said: "Especially the outer covering parts need to be stamped and sprayed. You need to build a new factory building."

The establishment of a new factory building is not just a few words. It requires a large amount of capital investment. Although the sales of Guangming motorcycles are booming now, if you invest a huge amount of money, the risk is still not low.

However, when Xia Nan looked at the picture Qin Shaoyou drew, his eyes had already betrayed his heart.

"Well, our factory also needs to expand. Let's build a new factory to produce these things. Don't travel. Do you think we can make real cars in the future if we go on like this step by step?"

Qin Shaoyou looked at his design drawing: "Of course, you can build four-wheeled ones in the future, and you can step into the threshold of passenger cars. Moreover, the shape of this car can be used at that time."

The old man is motivated, Qin Shaoyou needs to help!If this continues, next year, year after year, year after year, three years, maybe the father-in-law's motorcycle factory will really build a QQ and eventually become a national car?

Whatever the people need, Guangming Factory will produce. This slogan is not bad.
