Chapter 551: suspension

Biquge EbookFREE.me, update my latest chapter of the third empire as soon as possible!
The Soviet Union, the Ural mountainous area arsenal, code-named 9137 project, has now been completed and is in operation for the ribbon cutting ceremony. This project includes the establishment of a series of tank production plants in Chelyabinsk, turning this into a city specialized in tank production.
The chimney erected like a forest here proves its magnificence and magnificence. If you count some technical workers withdrawn from Minsk, Kharkiv and Donetsk, there are 30,000 employees here It is another industrial heart of the Soviet Union.
Of course, this factory is an important base for the Soviet Union to produce tanks, and the lathe equipment set up with the help of American engineers is also preparing to serve the production of new Soviet tanks. This tank is a war monster carefully designed by Soviet scientists and a decisive weapon for Stalin's high hopes.
This tank is equipped with a 76 mm caliber tank gun, which is modified from the Soviet anti-aircraft gun, it is very practical and more powerful than the main gun of the kv-1 tank, but this tank is better than the kv-1 tank. Need less steel. Like the German tanks, the entire tank uses tilted armor plates. The only difference is that this tank has a hatch on the front armor plate.
This tank has 7 load wheels. Of course, this is directly related to Germany ’s preemptive purchase and confidentiality of the Christie tank suspension system. The Soviet Union did not get the relevant patents and technologies, so it could not come up with any decent shock absorption solution for a while. Had to use the technology on the kv-1 tank for the time being.
Of course, it must be said that under the circumstance of mistakes, the Tiger King tank being developed in Germany and the t-34 tank being prepared by the Soviet Union both use "torsion bar suspension", and the experience of later generations proves that the torsion bar suspension is the The mainstream choice for tank suspension systems. This suspension has many advantages over the Christie suspension currently used in German tanks.
Because the Christie tank suspension is designed by the principle of spring force, this suspension takes up a lot of space inside the car body, which also makes the t-34 tank in another time and space, and this time and space Akado dominate the production The internal space of the German Leopard Tiger tank is somewhat messy, which affects the storage of ammunition and the placement of equipment.
This was also caused by Akkado's misleading "t-34 tank mythology" he heard. In fact, in view of the simple structure and space utilization, the torsion bar suspension is a tank suspension method generally accepted by everyone.
What is ridiculous is that the criticized suspension system of another Tiger and Leopard tank produced by Nazi Germany in space and time is precisely the American M1 main battle tank, the German Leopard 2a6 main battle tank, and China's 99-type main battle. Tanks, the torsion bar suspension commonly used in Russian t-72 and t-80 main battle tanks. On the contrary, the Christie suspension adopted by the mythical T-34 tank was completely eliminated.
Why is this so? In fact, this needs to be explained from the Germans' own suspension design: German tanks do use a more advanced and simple and reliable suspension system, but because of their perseverance and lasting hardship, they put a simple and advanced suspension system Changed beyond recognition.
To put it simply, the torsion bar suspension must stagger the position of the load wheels on both sides to place the "torsion bar" that needs to traverse the entire car body, which also causes such a "fault" of the asymmetry of the load wheels on both sides of the tank. Of course, this asymmetry does not affect the daily use at all, but for Nazi German designers in another time and space, it is simply an unbearable "disaster".
As we all know, another space-time tiger tank and leopard tank use a staggered load wheel structure. This structure is forced to adopt because the rubber weighing capacity on the edge of the load wheel is insufficient. That is to say, Germany must try its best. Under the limited length of the car body, more load wheels are installed to support the weight of the entire tank. So for the torsion bar structure, engineers need to install more torsion bars-Tiger and Leopard torsion bar up to 16, so that the simple structure advantages of the torsion bar disappeared immediately.
Of course, another reason to make the tiger and leopard-type walking mechanisms more complicated is that Hitler and the German designers have looked for them themselves-they ca n’t stand the asymmetry of their tank load wheels, so they used a method to make the complex interlace The wheel is symmetrical ... Is it beautiful? Are you surprised? With so many Virgo German designers and leaders coming together to appear in the history of World War II in Germany, it really makes people cry.
Coupled with the problem of the small horse-drawn cart of the Tiger tank itself, the problem of gearbox failure, it also caused an illusion that later generation scholars were caught in the wrong area: the structure of the t-34 tank is simple and there are few failures, while the structure of the Tiger tank is complicated and many . This is actually a very wrong argument, at least not quite comprehensive.
If you take a closer look at the technology used by the German tanks of World War II, you will immediately understand that the Germans themselves have drawn a strange circle for themselves, plunging themselves into the "evil road" of tank performance.
German smelting technology was developed, and a process called surface hardening was discovered, which made the armor quality of German tanks to a higher level. However, the price is that the German surface hardening process will increase the weight of the metal-similar to the 100-steel steel mentioned in the martial arts novels, the density will naturally affect the weight.
So while increasing the protection, the weight of the German tank rose to a new height. Coupled with the use of staggered load wheels and double torsion bar weight gain, German tanks at that time basically have an incredible weight. Of course, the benefits of double-row staggered load wheels are undoubtedly, the comfort and stability of the tank is unparalleled.
I do n’t know if you feel that these performance improvements are all good aspects: the tank ’s armor is thicker and the walking device is also better. Of course, if you count the consistent reputation of the German tank gun and the German aiming system, We are far ahead, and we will find that this tank is infinitely close to a word: "perfect". So now a new problem is coming-the armor is stronger, the walking device is more comfortable, and the artillery power is also arrogant to the heroes. Is this tank really without shortcomings?
The soft ribs are naturally on the engines and gearboxes of tiger tanks and leopard tanks. In order to make the tanks have extraordinary mobility, the engines equipped with these two tanks are naturally powerful and excellent in performance, but in that era, the performance improvement zone What came was a linear decline in reliability, and the problem of an unusually high failure rate appeared. Another terrible problem is fuel consumption. The nickname Oil Tiger is not a worthy name.
Suppose you bought a car, the driving feels great, the safety system is perfect, the interior is beautiful, and the appearance is enough to reflect your noble taste. Is this car really perfect? Is it expensive when repairing a car? Did you vomit blood when buying a car? Is fuel consumption per hundred kilometers inducing tears? You may be rich and do n’t care about these shortcomings, but have you ever thought about what kind of disaster it is when you own tens of thousands of such cars and must use them every day? Hitler and his logistics department were facing such a disaster at that time, so they lost nothing wrong.
In this time and space, the Germans did not fall into a terrible strange circle. Their tank weight has been maintained very well. The good bulletproof shape has made up for the thickness of the armor to a certain extent. At this time, the German tanks are steadily moving towards the main battle tanks. To move forward conceptually, not to the path of no return to heavy tanks.
Hitler dug the pit, and Akado jumped back. He bought the patent of the Christie suspension system and kept it strictly confidential. He used this actually very backward suspension on the new German tank Leopard and Tiger. It also felt complacent that it simplified the German tank and reduced the failure rate.
When German engineers did not have to struggle with such boring things as "left-right symmetry", when German engineers did not have to sigh for the quality of the rubber on the edge of the wheel, they naturally found a tank suspension system that was more suitable for war, that is The torsion bar suspension proved by time.
The layman, Akado, was also stunned by the data calculated later. At this time, he realized that the so-called t-34 myth is sometimes not true. He admitted the error and ordered the decisive use of more advanced torsion bar suspension in the design of the next-generation German tank Tiger King.
Now the Soviet Union's most advanced t-34 tank also uses torsion bar suspension, and more avant-garde with a rear gearbox. This tank also has a sloping armor plate and has an excellent bulletproof shape. The 76mm caliber artillery can also threaten the early Leopard tanks that were put into production in Germany at a distance of 500 meters. It is fully equipped with the German tanks. Struggle for strength.
Today, Stalin arrived here, inspected the production of the entire factory, and personally painted the last piece of paint on the first t-34 tank off the production line. Surrounded by applause, the Soviet Union's first advanced t- The Type 34 tank was officially put into service, and was immediately loaded onto the train and sent to the Ukrainian front to participate in a new counterattack.
This time, the Soviet Union mobilized 500,000 troops from the Far East and dispatched all the troops they could draw to the front. It was quite well prepared. The Soviet high level knew very well what would happen if Ukraine left the country for a long time, and the anti-Soviet wave there was stronger than expected.
With the battle-hardened soldiers and new weapons, the Soviet Red Army has made a certain investment this time. This time, Stalin decided not to let those who engage in politics intervene. He prepared a real military commander for the millions of troops on the front.
