Siheyuan: This driver is too arrogant

Chapter 342 Be so advanced and do it! (seeking subscription)
There are many kinds of gearboxes. At present, the gear transmission gearboxes from the Soviet Union are used in China. The structure is simple, the operation is laborious, and the failure rate is extremely high.

The more advanced gearboxes in later generations are divided into AT, CVT and other gearboxes. Even in later generations, CVT gearboxes are extremely difficult to manufacture. Several large automobile manufacturers have spent decades without overcoming technical difficulties, and still rely on a large number of imports. Fill the domestic market.

This is very embarrassing.

As for the CVT that Liu Weidong wants to build now, the country does not even have the concept of this aspect, and is still addicted to the dream of the simple structure and durable leather of the Soviet-style gear box.

The CVTs sent to FAW last time were all said to be good after use. They feel silky smooth, the shifting is brisk and powerful, and their performance is solid and reliable. They also disassembled two of them. After some research, they came to the conclusion: not come out.

The structure is too precise, and the strength required by many internal components is far beyond the existing smelting and forging conditions. If you concentrate on big things and spend three to five years, you may be able to make one like a cat, but the cost will be horribly high. !
FAW sent letters several times, hoping that they could mass-produce the CVT, and even offered favorable conditions: as long as the cold-rolling mill can produce this gearbox, they can apply to the Planning Commission to list the cold-rolling mill as a long-term supplier. Merchant ranks!
Being able to hug FAW's thigh is quite a temptation for Liu Weidong.

only……

The manufacturing difficulty of the continuously variable transmission is really high, so high that he has to start from scratch.

The first step from scratch is to start with steelmaking.

After the ironworks was captured by him, he has been training workers for the past few months, and now he can basically smelt standard manganese steel, nickel steel, chromium steel and other alloy steels. After forging and cutting, these It can be used as a part of a continuously variable transmission.

The CVT that Liu Weidong wants to produce is a simplified version of the gearbox of the later generations. It has no electronic control components and is completely mechanical. The difficulty of production is much reduced. Of course, the performance is also a bit worse than that of later generations.

After the steel was forged, another problem lay in front of us: the lack of processing equipment.

He didn't like the junk products produced by Shenyang Machine Tool Factory; he wanted high-end products from Germany but couldn't get them. Liu Weidong was so worried that his hair turned gray several times!

How to do?
Need something to find the system?
System: I have all CNC machine tools here, you can use them if you are not afraid of being exposed!

What the hell!

Liu Weidong scolded, being so advanced, do a yo-yo!

Looks like I have to figure it out...

He yawned and stood up, glanced out the window, it was already dark at this time.

There was the sound of children laughing and playing outside the door, and Little Gege brought the two little babies over to find him and go home for dinner.

"Father's desk has a lot of books too!" Sitting on the chair, Xiao BuDian grabbed a book and looked at it, pouted, "It's not pretty at all!"

"Haha, you are so stupid that you can understand a ball!" The older brother unceremoniously launched a personal attack on the younger sister.

"Brother, Abu said he would go back to the grassland to stay for a while, so you can send him back tomorrow, and send these two brats there as well. They are playing around at home every day, and I can't study anymore!"

Little Gege looked at the two brothers and sisters who started bickering again, with a helpless expression on their faces.

"Good daughter-in-law, don't worry, daughter-in-law!" Liu Weidong stared, "Do you two still want to go home for dinner?"

"Stupid brother, let's go, daddy is calling us to go home for dinner!"

Liu Weidong was taken aback for a moment, this sentence...

It sounds so familiar!
Relying on his unparalleled prestige in the Mengdong grassland, the old prince deterred those who were ready to move, and successfully helped the Mengdong region to pass through the special period smoothly. He also retired and was appointed as a member of the advisory group, and began to enjoy retirement.

He didn't live comfortably in the city. Although his superiors arranged a hotel for him, he always felt uncomfortable lying on a soft bed with his old body. What's more, he didn't have two grandchildren by his side. He always felt empty inside.

So as soon as the superior announced his retirement, he couldn't wait to ask his son-in-law to send him back to the grassland!

No place is as good as home!

In the city, I don’t want to stay longer than one day!

Little Gege still had to go to class, so he couldn't see off old Abu, and little Cai'e also had to go to school. Liu Weidong drove the car, carrying his father-in-law and two children, to Huangcaoling.

"Ho Ho go home!"

The little one was so happy that he jumped up and down, pinching his big brother's little face from time to time, which made his big brother very angry!

"Blessed by the Longevity God, we haven't had a big black disaster for so many years. It's rare!"

Looking at the green grassland outside the window, the old prince said with emotion.

"Dad didn't tell you that, as early as two years before Yanyan and the others were born, there was a severe drought, and all the grass died. Later, they drove the cattle and sheep to the Shengli Dam, and survived by relying on that. Only the water can tide over the difficulties..."

"Then why didn't you tell me when you wrote the letter?"

"Isn't it because you're always worried!" Liu Weidong smiled, pointing to Hai Dongqing flying around in the sky, "Seeing that there is no father, Hai Dongqing is here to pick up Yanyan."

"The two of them have become good friends..." The old prince stuck his head out of the car window, looked at Haidongqing flying around in the sky, and whistled.

Hearing the whistle, Hai Dongqing slammed down and slammed into Xiao Budian's arms with a bang, knocking the little girl back half a meter!
"It hurts so much!" Xiaobudian frowned in pain, picked up Haidongqing, and kissed him vigorously, "Does Big Bird miss me?"

"Think about it, miss him to death!" Xiao Zhengjie was beside him, holding his throat to make fun of it.

"Brother Smelly is ignoring you!" Xiao BuDian hugged Hai Dongqing and sat in the carriage. Hai Dongqing put his head on her shoulder and screamed, looking very excited.

Xiao Zhengjie grabbed a straw and bit it in his mouth, staring straight at the big bird in his sister's arms with envy on his face!
The car stopped at the door of his yurt, and Ao Qier led a team of chubby dogs to run over and line up to greet him!
"Big dog!"

Liu Weidong carried the little one off the carriage, and this guy, like a restless caterpillar, couldn't wait to land on his feet, and rushed towards Ao Qier!
Aoqier's big tail was wagging like a windmill, and he kept licking the little master's face with his tongue, making the little girl giggle.

"Big dog!" Little Zhengjie also rushed towards the hound Enzina, but Enzina just gave him a blank look, and stood by the little one, stomping his feet anxiously, waiting to be caressed by the little master.

Xiao Zhengjie looked at the dogs surrounding his sister, and then saw that there was nothing around him, his nose sore, his mouth deflated, and he burst into tears!
So bullying!
Even big birds and dogs bully people!

In the distance, a red-and-white colt ran over and arched his arm with its big mouth. Xiao Zhengjie wiped away his tears, hugged Sui and Zhuifeng's child, and cried with a crying voice. Crying that this is my horse, you are not allowed to have it!

"Cut, who cares!" The little one is "receiving" his "subjects", how can he have time to pay attention to his stupid brother?
"Hmph, we are the best in the world, not you!" Xiao Zhengjie hugged the pony's neck and glared at his sister.

Chasing the wind ran to Liu Weidong's side and rubbed his arm vigorously. Liu Weidong patted the horse's head, and the beast lowered itself, quietly enjoying the care from its owner.

"This horse is so beautiful!" The old prince came over, and Zhui Feng mischievously opened his mouth to bite the old prince's arm. The old prince grabbed the bridle, and Zhui Feng tilted his head. The big eyes looked at the owner and asked him for help.

"Let's play!" Liu Weidong patted Zhuifeng's neck, and the guy flicked his tail and ran away.

Concubine looked around, as if she was looking for her master. Liu Weidong walked over and pinched the horse's ears, "Your master has to study, so he can't come back for now!"

Suu tilted her neck and looked at him, as if she understood what he said, her beautiful big eyes were suddenly covered with a layer of mist, she lowered her head, walked to her yurt and lay down resentfully, with a lonely look, Liu Weidong saw My heart is also sour.

This horse misses Little Grid.

"Ouch!"

Ao Qier rushed over and hit Liu Weidong's chest with his big head, causing him to grin in pain.

The guy's two front legs were resting on Liu Weidong's arms, his tail was wagging like a windmill, and he was panting with excitement. Only then did Liu Weidong remember what later generations said that when a dog sees his master fainting from excitement, it's not nonsense, but a real thing .

For example, this one in front of you.

He picked up Ao Qier and turned around in a circle. The dog sticks out his tongue and has a happy smile on his face!

oooooooo!
Master is back!
So happy!
"Haha!" Aunt Ayisi came over and patted Ao Qier on the head, "Weidong, you don't know how powerful your dog is. It killed the fox that stole the lamb two days ago."

"Awesome!" Liu Weidong pinched the dog's ears, and Ao Qier probably understood that Aunt Ayisi was praising it, so he immediately calmed down, squatted on the ground obediently, raised his head, and accepted the praise like a victorious general.

Liu Weidong took out a piece of beef jerky and stuffed it, Aoqier put it in his mouth, turned his head to look at a four-eyed Mongolian mastiff dodging beside his yurt, ran over, put the beef jerky at its feet, and barked One sound.

"This guy really loves his wife!" Everyone laughed.

The yurt had been unoccupied for a long time, Liu Weidong and the old prince Weng and his son-in-law worked together to tidy up the house. Looking at the gold nuggets placed under the bed, the old prince winked at his son-in-law, "Weidong, you don't care about these things." How are you going to deal with it?"

"Keep it for now, and when there is a chance to turn it into cash, let's do a big thing for the herdsmen!"

"What's the big deal?"

"Dad, don't get to the bottom of it! You don't have any sense of mystery when you say it."

"This boy!" The old prince smiled and patted him on the back of the head. He treated this "half" like his own son!

"This kid, mischievous, not good at all!"

The little boy ran in and parroted his tongue.

"Aren't you looking for a beating!" Liu Weidong picked up a feather duster and chased him out.

The old prince looked at his son-in-law and granddaughter with a smile on his face, and suddenly sighed. If my two Fujin are still alive, I don't know how happy I would be to see this warm scene!

Ugh!
In spring and April, spring is already warm and flowers are blooming in the south, but the grassland is still warm and cold, and there is still ice and snow in the shade. Goose-yellow grass sprouts stubbornly emerge from the burnt grass, enjoying it to the fullest Sunshine and rain.

Batu led the herdsmen to ferment the manure in the septic tank for a whole winter. The already decomposed manure from cattle and sheep was collected, loaded into a Lele cart, and sprinkled on the grassland along the way to fertilize the grassland.

The bell of the Lele car moved from far to near, and stopped in front of Liu Weidong. Liu Weidong walked to the side of the Lele car, grabbed a handful of wet manure, and sniffed it to the tip of his nose.

The decomposed manure exudes a faint sour smell and is black and shiny. It is best to use this kind of manure to nourish the grass.

"Look, Weidong, that piece of grass was manure-spread three days ago, how vigorous it is!" Uncle Batu said excitedly, pointing to a piece of green grass in the distance, "The grass that was sprinkled with manure turns green early, and it grows so vigorously." Come on, cows love to eat it!"
