On modern tanks, the wheels with power output are front and rear inducers, and the other wheels are unpowered load-bearing wheels. If the track is broken, the wheels will naturally turn and fly, but even if its displacement is 1 mm, you can't see the tank.
However, although the Soviet T-34 tank used Christie suspension in World War II, in order to facilitate mass production, the T-34 gave up the dual-purpose function of wheels and shoes, and its suspension system did not output power separately for each load wheel. The Soviets soon invented another kind of suspension system, which has been used by various countries to this day.
In order to realize the universality of wheels and tracks, it is necessary to make each load-bearing wheel have independent power output. The corresponding structure is only hung by Christie.
In order to make each load wheel have independent power output, Christie's suspension structure is very complicated, and the big spring in the pit greatly limits the height of the tank. However, this suspension itself involves dual-purpose vehicles.
Christie's suspension was made by American Christie. He also made a Christie tank, but the US military was not interested. Then Christie went to Britain and the Soviet Union with her works, and the British bought technology to play. The Soviets were developing tanks at that time, and they thought Christie's things were very exciting, so they bought patents and studied several Christie tanks. Later, the Soviets developed BT series fast tanks on this basis. BT series tanks run very fast by virtue of the high power of the engine and the excellent mechanical properties of Christie's suspension.
Modern tanks are mostly suspended by torsion bars. It was first used by the Soviets on the T-44.
The torsion bar suspension has the advantages of simple structure, high reliability, convenient maintenance and less occupied space. The torsion bar made of spring steel has a fixed end. When the fixed end is stressed, the angle changes, which will make the torsion bar twist.
As the most important land combat weapon in modern warfare, tanks play a very important role in the battlefield. Today's tanks have different frame structures in appearance because of their different main functions. However, no matter how the frame structure of a tank changes, one thing belongs to all tanks, and that is that each tank is equipped with a "crawler belt".
As a tank of tracked armored fighting vehicle, crawler can be regarded as the most basic configuration. It is precisely because of the configuration of tracks that can support steel that tanks can move freely in extremely harsh combat environments, as if walking on a flat road. At the same time, the crawler increases the stress area between the tank and the road surface, so that the tank can firmly grasp the ground without slipping. As the action device of the tank, the crawler is enough to be called the feet of the "king of land warfare".
Tracks are so important to tanks, so if the tracks on the tanks are broken, can the tanks move on?
The answer is of course "no". As we all know, there are many wheels, large and small, which are all wrapped by tracks. The track is broken. Why can't these wheels continue to provide power for the tanks? Although there are many wheels in Tanqueray, most of them are load-bearing wheels, which bear the weight of tanks. The wheels responsible for the tank's progress are only two inducers located at the forefront and the last side. Therefore, when the track breaks, no matter how hard the larger load-bearing wheel under the tank tries, the tank can't move forward, even if it is 1 cm.
There is a simple reason. The wheels on the track are divided into driving wheels and driven wheels. The driving wheel has power output to drive the whole crawler to run, while the driven wheel has no power and cannot rotate by itself. Once the trajectory is lost, it will stop at the same place, and the driving wheel will still rotate at high speed driven by the engine. At least so far, all main battle tanks are designed like this!
Therefore, the track of the tank is indispensable for the tank. If the track of the tank is broken, the tank will certainly not be able to move on.
The largest load wheels on both sides of the tank chassis do not provide power. Only the driving wheels at both ends of the track can provide forward power.
BT tanks in the early years of the former Soviet Union can run without tracks.
There is a training in the tank unit, which requires how to drive forward when the track on one side of the tank is broken. In wartime, this will help to maintain our own combat effectiveness. As long as we can persist in returning to the safe area, we can replace the damaged crawler and restore our combat capability.
We all know that the mobile armor of a tank is composed of crawler, driving wheel and load-bearing wheel. The driving wheel, also called the driving wheel, is a gear-like device with the rear parts on both sides of the tank higher than the load-bearing wheel. When the tank is running, it is used to drive the crawler to move forward, while the load-bearing wheel itself has no power and only plays the role of bearing and supporting the weight of the tank. If the track on one side of the tank is broken and the other side is intact, the tank can move on. Only one side of the broken track will lose its steering ability, and at the same time, it is necessary to constantly adjust the direction during driving to prevent the car body from deviating to the side without track. In addition, the steering process is only a little troublesome. Generally, when you meet an intersection and need to adjust the direction of the car body, you will reverse the car or use the inertia of the car body to complete the U-turn. In short, it is definitely not as convenient as a tank with intact tracks.
Because the power of the tank is provided by the driving wheel, when the tracks on both sides of the tank break, the driving ability is really lost. If we don't carry out the repair work in the same place, we will have to give up the tank.
German R-R Kampfwagen M28 dual-purpose tank
Some early tank models used the dual-purpose action mode of wheels and shoes. This tank can still walk on wheels even if the track is damaged. For example, early Soviet BT series tanks and German M28 dual-purpose tanks; For example, in the test of M28 in Germany, the Germans thought that the design of this tank was too complicated and unreliable, so they gave up and did not develop further. BT tanks in the Soviet Union were quickly eliminated because of this unreliable and complicated maintenance. No matter how fast you run, it is useless. You don't need to know how deceptive unreliable weapons are ~ ~ ~
Subsequent tanks rarely use this combination of wheels and shoes. Besides complicated design, troublesome maintenance and poor reliability, the increasing weight of tanks is also the main reason. If the heavier car body adopts the wheel shoe structure, it is estimated that the ground crew will go crazy. It's hard to imagine what a 60-ton tank would look like with a tire running device ~ ~ After all, there are still a few G6 self-propelled guns in South Africa.
Tank is a steel fortress on the battlefield. The huge weight and flexible posture seem to be mismatched, but it is actually caused by the unique crawler design of the tank. Excavators, tanks and other heavy machinery. They are all crawler-type, so if the crawler suddenly breaks on the battlefield, can you rely on the load-bearing wheels to move on?
The tank we usually watch seems to have many wheels, and each wheel is moving when it moves forward, as if the wheel has its own power to drive the crawler to move forward. What is the real situation? In fact, among the many wheels of a tank, only the front and rear wheels are real driving wheels, and the rest of the grounded wheels are load-bearing wheels, which means that they do not provide power. What if they are blown off by the enemy on the battlefield? In fact, the army has thought about this problem in advance and conducted special training. What if one of the tracks of the tank is broken? In fact, if only one side is broken, you can barely move forward, but the direction will be difficult to control. At this time, the driver's superb skills are needed, because when moving forward, it will tend to break the edge and need to constantly adjust the direction. If you can support returning to the base, you can re-enter the battlefield after changing your defense. If both sides break at the same time and have no ability to repair the battlefield, I am afraid it will really become an iron knot.
The driving wheel and load-bearing wheel of modern tanks are separated, so why not design them as dual-purpose wheels and rails? In fact, some tanks did adopt this design in the past, but later actual tests found that this structure was too complicated to be suitable for complex and changeable battlefields, such as BT tanks in the former Soviet Union.
Of course not. The load wheel is just a suspension system that provides load.
But there is always something different, such as Christie's bt series. Because one of his load wheels is connected to the power wheel behind him. So even if there is no crawler, it can be moved by the load-bearing wheels.
Others, such as T34, used Christie suspension, but because the power was not distributed to the load-bearing wheels, they fell off the track or fell down.
You can't.
The function of the crawler of the tank is to transmit the power output of the tank to the ground through the crawler, and the load-bearing wheels of the tank support the tank to reduce the pressure.
The load-bearing wheels of the tank do not bear the power output, so as long as the track of the tank is broken, the tank can't walk. Even if the tank is fully driven, the wheels are too smooth and have no friction to move forward.
The tank power is transmitted to the track and then to the ground through the inducer at the top of the tank.
The load-bearing wheel is just a supporting structure with suspension.
No, the brake wheel of the tank does not touch the ground, so the driving force cannot be formed.
(Even if the brake wheel touches the ground, it is difficult to move. ) and the load-bearing wheel is just a support and has no power. In this case, it is absolutely impossible to move the tank unless there is an external force to push it.
Although the tank has many wheels, isn't there an obvious feature that you can't see? The hard wheel doesn't carry a load, and the heavy wheel doesn't work hard ... Let's not talk about it in the future, shall we?
