Chapter six hundred and ninetieth labor is the most glorious
Any vehicle needs to have shock absorption, otherwise, if it is directly connected rigidly, the vibration of the ground will be transmitted to the vehicle body, and people there will be unbearable.
Take cars for example. Trucks use steel springs, which are quite hard and uncomfortable to ride. The van also has this kind of suspension. For cars, the low-level overall suspension and high-level independent suspension are quite comfortable to ride, especially
For millions of high-end cars, if you use air suspension and do not slow down when passing the speed bump, you can see that the car body is as stable as Mount Tai.
On tanks, suspension has also undergone many improvements. During World War I and World War II, suspension with large coil springs was once popular, but it occupied too much space. Therefore, in the later stage, after the continuous improvement of suspension, it was mainly used
The torsion rod is suspended.
Speaking of which, it is slightly similar to the suspension of the torsion beam. A torsion bar crossing the car body, with two sides extending in two directions, and then, when encountering bumps, the load-bearing wheel
It will drive this shaking handle, tighten the torsion bar, and use the elasticity of the torsion bar to achieve shock absorption effect.
From World War II to now, this is the main way for tanks to hang. Even the most advanced Leopard-2 tanks use torsion rod suspension. As for the more advanced than torsion rod suspension, it is gas-liquid suspension.
There is an air-liquid action cylinder on each wheel for shock absorption. Although this method looks very advanced, it is very difficult to process. The original three-liquid sample car used this kind of suspension, which was quickly announced.
If it fails, oil leakage is an unsolvable problem.
The 321 chassis also uses normal torsion bar suspension, but because the two front and rear load wheels are too far apart from the middle load wheels, the front and rear load wheels have too much stroke when the front and rear load wheels are bumpy, which will lift the torsion bar.
There was a serious challenge. After a long time, the torsion rod broke due to metal fatigue, which was common.
Now, Wang Erzhu has seen this problem.
"It is not enough to only increase the strength of the torsion bar because it bears too much force." Qin Zhenhua said: "We need to find a different approach. I suggest adding two pairs of hydraulic shock absorbers in these places."
If you just use the torsion rod, you need to use a hydraulic shock absorber and solve the problem with two-pronged approach.
Everyone sat together, studied the drawings for three or four days, and made more than 100 pieces of technology improvements, and wrote them all in the book. Then, detailed designs were carried out, and after completion, they could create a prototype chassis sample car.
It's right.
At the same time, the various procedures for Yimai Factory to build its own new automobile branch have been completed. After the approval procedures, a new and modern factory on the grassland underwent a groundbreaking ceremony and officially began construction.
This project of the first machine factory is eye-catching. After all, the current first machine factory has not yet been released any civilian products. They can improve it in their existing factories, but 69-2 tanks from the desert area
The orders have already been continuously rotated, and they have no extra production capacity to do this, so they can only be carried out by building new factories.
In China, this is the first time that without the investment of the state, one factory relies entirely on investing in the new workshops on its own. For this reason, a machine factory even borrows from banks in large quantities, which requires great courage.
The outside world is very concerned about this big move by the First Machine Factory, but what I care most about is the project of the 10,000-ton forging press that the First Machine Factory is going to launch!
"Qin, there are too many problems here." Mia put on the work clothes of a machine factory and looked energetic. At this time, she was looking at everything in front of her with full energy.
There are many difficulties to overcome in manufacturing this 10,000-ton hydraulic press. According to the plan, this is a four-column and three-beam structure equipment, among which three beams are huge iron lumps.
Now, if you want to process these beams, it takes a working face of ten meters long and eight meters wide to be processed.
There is no planer over ten meters in China. Now, what everyone adopts is the new method proposed by Qin Zhenhua!
Five mobile milling machines have been moved to the beam processing site, and everyone needs to use these mobile milling machines to process them together.
"Yes." Qin Zhenhua said: "We have a saying that workers' wisdom is endless. We workers must exert the subjective initiative of workers."
"Well, then let's start."
The five mobile milling machines are controlled by five most skilled workers. Among them, the most critical middle three milling machines are operated by Qin Zhenhua, Miya and Wang Erzhu. Once the operation starts, then,
After a few days or nights, you can’t close your eyes, you must successfully operate it in one breath!
The milling machine is running, and the metal wires are cut out and then taken away. More metal wires are cut out, and the huge steel ingots are deformed and deformed little by little.
Since it is five milling machines working together, the place where the five milling machines are intersecting is the most technical test. They are careful when cutting at the joints.
53 knife plates were flying in the air. The day passed. At night, they ate simple cans, their eyes were red, and their teeth were gritting their teeth to continue to persevere.
The next day, the third day, and by the evening of the third day, there was only the last knife left!
Qin Zhenhua carried dozens of kilograms of knives and looked for a suitable angle on the workpiece. At this time, although everyone was already quite tired, they were still shrouded in huge excitement.
Finally, the last knife was completed! The first beam was successfully processed!
Mia's body was also very tired, but looking at the processed beam, Mia's eyes were still full of surprise: "I really didn't expect that this large workpiece can be done in this way!
It's incredible, this is a miracle! I've never seen it in Germany!"
"Yes, Germany is impossible. How could they fight for three days day and night during the eight-hour work period?" Qin Zhenhua said: "Only our hard-working and hardworking people in the Eastern country will have such a dedication.
.”
Qin Zhenhua was right. In the West, the initial primitive accumulation of capital has passed, and they have begun to enjoy a wonderful life. Do you want to work overtime? Don’t joke, don’t do much money, the union will protect them.
Therefore, they live a very comfortable life, and in this comfortable life, they are surpassed by the workers who work day and night in the Eastern powers.
