Chapter 48 How to Forget the Torsion Bar Spring

In the place where Chen Geng's line of sight looked, there were three Type 63 armored transport vehicles, and the design of four pairs of load-bearing wheels looked particularly "cute".

As the third comprehensive large-scale ordnance repair plant under the East China Military Region, the third ordnance repair plant has the ability to repair Type 63 armored transport vehicles, but this kind of good work is generally not the turn of the third ordnance repair plant, usually once this kind of good thing appears, it is immediately snatched away by the first and second ordnance repair plants, anyway, in Chen Geng's memory, from the memory to the present, the third ordnance repair plant repairs armored vehicles, The number of high-tech military armored vehicles such as tanks can be counted on one hand, and it is even an honor to see armored vehicles at the Third Ordnance Repair Plant.

Many people may not believe it when it is said that our army is equipped with few such armored transport vehicles, and it means that our country has also developed several types of tank armored vehicles?

It is one thing to develop several models of tanks and armored vehicles, but it is another thing to equip the army, which not only costs money to procure, but also costs money to maintain the training of the army every year.

Our country's industrial base is very weak, the economic base is even weaker, to be honest, at this stage of our country & army is still not a modern mechanical force, mules and horses play an important role in it, mules and horses in the army accounted for a much larger proportion than military vehicles, this million disarmament, one of the very important goals is to promote our army from mules and horses to mechanization.

"You said those three armored vehicles," Chen Hongjun glanced up and said indifferently: "Isn't this going to become an enterprise?" ”

Chen Geng said "oh......", and immediately understood: this is the military region that has begun to sprinkle pepper noodles.

The equipment of the Type 63 armored transport vehicle is a very tall thing in our army at this stage, Chen Geng has never seen it before, and he has never had close contact in his previous life, so he is curious, so he wants to go over and take a look: he is also the deputy director of the Third Ordnance Maintenance Plant, and it is not illegal to get in close contact with this thing.

Cao Jun, who came with Chen Geng, looked at Chen Geng looking at the armored car, opened his mouth, and closed it again, Chen Geng is the deputy factory director, look at this car, no one can say anything.

Looking at this military armored car in the same way as a civilian vehicle, Chen Geng's evaluation was: "There is even a central lock, bad review!" ”

Although the design of the 4 pairs of load-bearing wheels is very "cute", it is also relatively speaking, with a pair of vicious eyes that have been trained in design for many years, even if the detailed size of the Type 63 armored transport vehicle is not clear, it is just an eye. Chen Geng still roughly estimated the general number of this car: the length is about 5.5 meters, the width is about 3 meters, and the height is between 2.55 meters and 2.6 meters.

"What did you say?" Chen Hongjun, who came with Chen Geng, didn't hear clearly and asked.

"It's nothing," Chen Geng shook his head, the military combat vehicle has a central lock, that's the hell, just just a pure complaint, said: "It's the first time to get close to an armored car, a little curious." ”

"Oh......" Chen Hongjun was suddenly relieved, young man, it can be understood: "These three armored vehicles will still be repaired for a while, and the engines will be pulled off." ”

Since returning to the Third Ordnance Repair Factory, Chen Geng seized the opportunity to go to the shooting range to pick up a shuttle, from 56 and a half to heavy machine guns, our army's active and retired light weapons, but can still be found, all played by him, and no one cares, who cares how many shuttle bullets the dignified company-level officer hits? Chen Hongjun took it for granted that his son was simply interested in military equipment...... Chen Geng is indeed just simply interested.

However, when Chen Geng saw the suspension structure of the Type 63 armored transport vehicle, he was not calm: Nima, this is ...... Torsion bar springs?!

"! How did I forget about this? He patted his head in annoyance, Chen Geng wanted to slap himself twice with his backhand, as a car designer, he forgot about such a classic combination, it really shouldn't be.

"What did you say?" Looking at his son's crying and laughing expression, Chen Hongjun asked suspiciously.

"Oh, nothing...... Dad, I suddenly remembered something, I need to go back to the office quickly, you tell my mom, I probably won't be home for dinner tonight......"

Before the words were finished, the people had already disappeared.

Cao Jun, who originally planned to take this opportunity to talk to Chen Geng about the contracted factory, was stupid: "Old Chen, Chen Geng is ......"

"Who knows what's going on with this stinky boy, he was shocked," Chen Hongjun didn't figure out what his son was suddenly smoking, but he was a little good, since he couldn't figure it out, he simply didn't ask: "No matter this kid, by the way, Lao Cao, you look for me...... Is this something wrong? ”

"It's okay...... It's okay......" Cao Jun had a bitter face, and never mentioned what he wanted to say to Chen Geng: As far as Lao Chen is twisted, can you tell him?

……………………

Not to mention Chen Hongjun and Cao Jun, only to say that Chen Geng, as if he was being chased by a dog, rushed back to the territory of China Resources Industrial, he couldn't take care of his breath, and ordered that no one should disturb him unless the sky fell, and the violator deducted half a month's salary, and rushed into the office and never came out.

Just when everyone was frightened and thought that Manager Cheng had been scolded at this factory leadership meeting, Chen Geng's office heard Chen Geng's proud laughter: "The only one who can design a front and rear four-link suspension for the 212 Jeep is Lao Tzu!" The only one who can design a torsion bar spring and a hydraulic shock absorber cylinder for the 212 jeep is Lao Tzu! Lao Tzu is really a genius! ”

What the hell is going on? What exactly is the manager stimulated? The young people of China Resources Industrial, who listened to the movements of Chen Geng's office with their ears pricked up, looked at each other one by one.

Without waiting for everyone to guess, Chen Geng had already opened the door of the office and ordered: "Go, call Zhang Xiangyang to me." ”

Immediately someone rushed away.

Zhang Xiangyang, who was dragged in, looked at the drawings in front of him, and his eyes were full of mosquito coils, which seemed to be a 4-link suspension modified from a 212 jeep, but why are there more things, what are these things for? Where did the coil springs go up?

Regarding Zhang Xiangyang's doubts, Chen Geng pointed to the drawings triumphantly: "Aren't you worried that without the shock absorbers provided by Wolf Castle, we will be blind, and now the problem is solved." ”

"This is your new design of the shock?" Zhang Xiangyang asked tentatively.

"Of course." Someone's smug nostrils are about to soar.

After staring at the drawings for a long time, Zhang Xiangyang asked cautiously, "But...... What about springs? ”

Zhang Xiangyang swears that there is absolutely no spring on this drawing, there is no coil spring on the Nima car, and there is no leaf spring, what does it rely on to absorb shocks and vibrations? If it weren't for the years of friendship that Zhang Xiangyang knew that it was impossible for his brother to joke with him about this kind of thing, he would definitely turn around and leave.

Chen Geng stretched out his hand and pointed at a pole connecting the steel beams of the body chassis and the wheels on the drawing: "Spring? This is. ”

"Is this a spring?" Zhang Xiangyang said, "Although I don't read much, I'm not stupid, don't fool me with this!" He grinned, "I don't know the spring?" Are you clearly a metal rod? ”

"That's right, this is indeed a metallic feeling," Chen Geng nodded: "But this is also a spring, this is called a torsion bar spring, which is a kind of spring, just like a coil spring and a leaf spring." ”

"Torsion bar springs?" Poor Zhang Xiangyang was completely confused, although he grew up in a vehicle maintenance company, he had never heard of the torsion bar spring, and hesitated for a long time before asking: "Are you sure...... Can this thing really be a spring worker? ”

"Now there are three Type 63 armored vehicles on the factory side, and they use torsion bar springs, what do you say?"

Zhang Xiangyang immediately believed it: the third child has said it to this point, although he still doesn't understand such a steel bar...... In Zhang Xiangyang's view, this torque bar is actually no different from the No. 12 rebar used to build a house...... How did it play the role of a spring, but since the words have been said to this point, the third child will definitely not joke with himself.

"Let me tell you this, a torsion bar spring is a rod-shaped spring, even though it looks like a metal rod...... Of course, it's actually a metal rod...... But the use of chromium vanadium alloy spring steel material, in the production process after quenching and pre-twisting process made, one end is fixed on the frame, the other end is connected with the wheel, the wheel will jump up and down when advancing, at this time the torsion bar connecting the wheel and the body will produce torsional deformation, in the process of torsional deformation, the torsion bar spring will rely on the torsional elastic force to absorb the energy of the wheel vibration, play the same role as the coil spring and leaf spring. And compared to leaf springs and coil springs, torsion bar springs have a higher energy storage capacity than both......"

Chen Geng said while writing and drawing on the paper, explaining to Zhang Xiangyang that he understood the working principle of the torsion bar spring, and if he didn't explain to Zhang Xiangyang, Zhang Xiangyang would take this thing to persuade the customer to pay for it in the future, if he couldn't understand it himself, how could he expect the customer to take out his wallet?

Chen Geng said in simple terms, Zhang Xiangyang quickly understood, and nodded again and again: "I understand when you say so, in short, even if we don't have the coil spring provided by Wolfsburg, as long as we have this torsion bar spring, we can also make the 212 jeep very comfortable, and this torsion bar spring can be produced by our country, right?" ”

Chen Geng: "That's right. ”
