"If you want to talk about ten-wheeled armored vehicles, there are examples in the international arena. Switzerland has such an armored vehicle." Nie Qianqian, as the head of the Tank Armored Vehicle Magazine, knows these things the best. Since Qin Zhenhua proposed to build a ten-wheeled armored vehicle, Nie Qianqian ran over to be a staff officer.
As she said, she turned on the projector and connected her laptop, and a beautiful wheeled vehicle appeared on the projection screen.
The biggest difference from other vehicles is that there are ten wheels of this kind of vehicle.
"When they first developed it, they used six-wheel and eight-wheel structures. However, in the 1990s, they began to develop a new Piranha 3 series, which added a set of tires, so the chassis of the entire car turned into a ten-wheel structure."
The wheeled vehicles of the Eastern Powers also went through this process. At first, they had six wheels, but now they were eight wheels, and then they had to move towards the ten wheel structure.
"On the surface, it seems that there is no big difference from the previous cars." Wang Erzhu couldn't help but sigh.
"Yes, you are right. When Switzerland developed this vehicle, it actually lengthened the body of the original eight-wheel chassis and added a bunch of tires, which became a ten-wheel structure." Nie Qianqian introduced.
"Although it seems that a pair of tires has been added, the performance has been greatly improved during the test. Because of the addition of this pair of tires, the bearing capacity of the vehicle body has been improved, so that more weapons can be equipped. At the same time, the internal space has been expanded and the armor protection has been improved." Nie Qianqian continued: "Of course, after adding tires, this also means that the car has better passability and easier off-roading. At the same time, when dealing with various injuries, such as less impact from landmines explosions. Even if one or two tires are damaged, you can still maintain a normal speed and continue driving. Of course, there are disadvantages, such as higher cost."
At this time, the upper part of the chassis was a tank gun. In China, the 105mm gun could be carried in eight large rounds, but the Swiss used this ten-wheel structure.
"After this car came out, it underwent a lot of tests. Its mobility is excellent. At the same time, even if the turret rotates ninety degrees, it will not overturn. It can be off-road at high speed. A large number of tests indicate that this car has a high reliability." Nie Qianqian introduced to everyone.
After she introduced the car, Qin Zhenhua said: "Since they can do this, we can do this too. It should not be difficult for us."
The new generation of wheeled infantry fighting vehicles developed by our side are also very advanced and the transmission system is also the latest, so it can be matched with a set of tires. What Liu Dajun wants can be made in a short time.
However, Wang Erzhu shook his head.
"I think this design is flawed," said Wang Erzhu: "The most important problem is the steering difficulties caused by adding a row of tires."
Wang Erzhu didn't agree with the Swiss saying that his car was very mobile and the like. He added a row of tires, which also had the consequences, and steering difficulties were one of them.
At the beginning, when researchers raised from six to eight, they would face the problem of steering difficulties. The solution was of course the first two rows were steering wheels, which would make steering easier. However, in order to better realize the steering function, the steering angles of the first row and the second row were still different, and the second row was slightly smaller. These were all explored through continuous research.
Now, lifting eight wheels to ten wheels, both sides are tires, and when turning, it poses a very high challenge to the tires.
"Then you think, how should we solve the problem?" Qin Zhenhua asked.
"If you add another row of tires, it is best to have the ability to follow the steering. When the two rows of tires on the front start to turn, the last row of tires must also follow the steering. In this way, the resistance in the turn can be reduced." Wang Erzhu said.
There are also ways to solve the problem, that is, to allow the last row of tires to be turned, so that the front two rows are steering wheels, the middle two rows are still moving, and the last row is also steering wheels. Only in this way can the problem be solved perfectly.
So, don't the Swiss know that this is more perfect?
We must know, but they did not do this because, if we do this, the mechanical complexity will be greatly increased. The original steering system is enough to be responsible for the steering of the first two rows of wheels. Now, the steering of the last row of wheels has to be added. If the complexity increases, it will also cause various potential mechanical problems.
So the Swiss simply turned a blind eye to this issue.
So, can you do this?
Wang Erzhu's attitude was firm: "If you want to build a ten-wheeled armored vehicle, you must carry the rear wheel steering, otherwise it will not be a perfect vehicle. We cannot provide such a vehicle to the army, it is irresponsible to the army."
Wang Erzhu has already made it clear. If you want to build it, you have to build a perfect vehicle. Otherwise, you would rather not build it, rather than be insignificant than be insignificant. Anyway, the current one-machine factory already has the confidence.
Qin Zhenhua nodded: "We cannot hand over immature equipment to the army. This is irresponsible to the army. On the battlefield, that is a crime. I agree with Director Wang. We must build such vehicles with better mobility and more flexible turns. However, we don't have to work behind closed doors. Internationally, if there are similar vehicles, we can also learn from them."
Speaking of rear wheel steering, this is not without precedent. Some advanced off-road vehicles have the function of rear wheel steering. Some heavy truck trailers also have the function of rear wheel steering in order to reduce the turning radius. These are all references to see what kind of steering method is the most suitable.
Wang Erzhu nodded: "If the factory agrees, then we can set up a R&D team as soon as possible to expand our wheeled infantry fighting vehicle to ten wheels. This is also meaningful. In the future, more weapon systems can be loaded, with a wider range of use, and more choices are given to the army."
