Super Weapon Exchange System

If you have a car modification enthusiast, you know that when changing a car, modifying the wheel is the most common, but it is the most technical test. After changing a wheel, although it feels stable to run, it is more bumpy.

Why?

There is a technical data called unsprung mass.

The wheels are not directly connected to the car body, so that the people in the car have to die. The middle is connected by softness, that is, the suspension system, which has the criticized suspension of the pallet truck, the advanced independent suspension, and the multi-link It is also called advanced equipment, etc., these can be collectively called springs, which connect the wheels and the car body.

The unsprung mass refers to the movement mass of the wheels, tires, and related accessories. It is conceivable that this weight should be as small as possible, because the smaller the mass, the easier it is to handle the spring, that is to say, the better the cushioning, which is reflected in the car, which is comfortable to ride.

The quality of the suspension system is an important implicit indicator of the car. It is said that a car is four wheels and a big sofa. You can look at the speed bump. When the Mercedes-Benz G has passed the speed bump, the body is stable and motionless. This is the power of the suspension system.

If the unsprung mass is very heavy, such a pit will cause the spring to move back and forth and the body will shake obviously.

In an ordinary car, the unsprung mass is mainly the wheels and brake system. If it becomes a hub motor, the motor will be inserted inside. You should know that the motor itself uses copper, permanent magnets and other metals, which are heavier than iron blocks. Therefore, the use of in-wheel motors will have this important problem.

There are many other problems, such as heat dissipation. The in-wheel motor is integrated in the hub, and the heat dissipation environment is poor, which can easily cause the motor to overheat. Once the motor is overheated, the permanent magnets will demagnetize in the slightest, and the motor will be burned in the worst case. There is also limited space in the hub. The motor cannot be made particularly large. Finally, it is reliability. To drive in a special environment such as sand, the motor must be of high quality.

For these reasons, it is difficult to put the hub motor of a car into practical application. In fact, it is first put into practical use. Instead, it is an electric bicycle. Almost all electric bicycles are hub motors on the rear wheels. Inside, if you have seen the most primitive electric bicycle, you can recognize it. A small motor drives the chain on the pedal behind it.

These issues are very complicated. However, for heavy trucks, especially the current super heavy trucks, they are not too big a problem. Take the most important unsprung quality, the main impact is the comfort of high-speed travel. However, The speed of this kind of large transportation vehicle is simply impossible to be high. Besides, the suspension and spring of this kind of super heavy truck are absolutely very powerful, and it doesn't care about the quality of one more motor.

This kind of super heavy truck, large off-road tires, and the space inside the wheel hub is also very large, enough to arrange the hub motor, heat dissipation is also no problem, and even the hub can be directly made into a heat sink.

Therefore, in that parallel time and space, the first to be put into use is the heavy-duty vehicles, including heavy trucks and large buses, which are the first to use hub motors.

Therefore, now Heribala mentioned the in-wheel motor, which is also well prepared.

"Moreover, we can also optimize in the system and add a set of batteries to the entire power system." Heribala said: "Because the engine always runs at full power, but the car does not necessarily need so many Power, so when the car is running at a low speed, the power can be converted into electricity and stored in the battery. Then, when the car needs power and the generator has insufficient power, the energy can be taken out of the battery for use, and, When the car is decelerating, you can use the in-wheel motor to generate electricity and transfer it to the battery. All of these can increase the car's cruising range."

These ideas of Heribala effectively improve the performance of their vehicles and greatly increase the intelligence of their vehicles. However, the same means that the Mas Factory must cooperate with them, because they have not involved in these. Starting from scratch is impossible.

"If a battery is added, the power of the engine can be reduced. There is no need to use this high-power gas turbine. I think it is enough to use our 700-horsepower diesel engine to drive a suitable generator." Barra said: "In this way, under the same fuel carrying capacity, the cruising range can also be greatly increased."

Why do they use gas turbines? It is because to generate electricity, there must be enough power to generate electricity, enough for the car to use, but now, the use of in-wheel motors can reduce losses, increase batteries, and increase the explosive power at critical times. In this way, the power system is reduced and it is enough. .

Although gas turbines have high power, they consume too much fuel. If they can be replaced with diesel engines, the cruising range can be doubled.

Musta listened carefully to these suggestions. In the end, the scholar said that using his own diesel engine is also a great advantage. It is a civilian engine. Therefore, the life of the engine is very long. Now, they need this kind of vehicle. High-power engines can only be considered from military engines. Although the power is large, the life span is too short, which is really tasteless.

The largest civilian diesel engine that can be used now is the Han Guo, 700 horsepower.

"Okay, let us develop together." Finally, Musta weighed the left and right, and made this decision: "Let us develop this kind of giant together and become a special car that makes the world tremble."

Anyway, they only care about making cars and what the tops are. They don’t care about it. However, if you simply think about it, you will know that the most suitable choice is to carry strategic ballistic missiles. This kind of size is still carrying all strategic missiles The largest equipment among them.

Let the world tremble!

Qin’s point of view: “I also believe that we will lead the reform of this technology. When this project is developed, it can also be used in many other solutions. For example, we can occupy a place in super construction vehicles and develop More civilian markets, that kind of super mining truck, can use this scheme."

If it is only for military use, the market is still very narrow. If you want to open up more markets, you have to deform it. That kind of giant mining truck is also a very important application.

For example, when our own Three Gorges Dam was closed, we used this kind of super engineering vehicle. By the way, this project should also be on the agenda. Now, with the rapid economic development of Han, the shortage of electricity is getting worse. It’s time to carry out this super water conservancy project.
