Finally, the power control box was repaired, and Musta let out a long sigh.
"How about it, done it?" At this time, Qin Guan and others have already come out. Such a broken factory, Qin Guan has visited with relish, which makes Musta a little strange, but also a little fortunate. Fortunately, the other party was not watching. Otherwise, it will be more difficult to troubleshoot.
"Yes, it's fixed," Musta said.
"Although the technical route of this kind of electric drive vehicle has long existed, it has not been mature for a long time. Therefore, it is very common for this kind of vehicle to break down in the middle of a problem. You should not be under psychological pressure." Qin Guan said.
Qin Guan said that, Musta's face was a little hot, and he felt normal.
In the earliest words, it should be said that it was during the World War. At that time, Hans State produced a Tiger tank weighing more than fifty tons. At that time, a group of Porsche doctors had a plan to use an internal combustion engine to generate electricity. Then use the motor to drive the track to rotate.
What are the advantages of this?
Naturally, it is to solve the problem of high-power power transmission. The heavier the tank, the stronger the power required. For the transmission system, it is a severe test. After all, the engine of the tank does not always maintain a rotation speed, but changes all the time. , Depending on the road, the accelerator pedal under the driver's feet is also different, the transmission system is very burdened, and problems may occur at that time.
However, the electric drive scheme was still not passed. Other than that, the heat dissipation problem alone is not easy to solve, and the motor is often burned.
Later, with the continuous improvement of the power system, the transmission system has also stabilized. Now, the transmission system of more than 1,000 horsepower is not a big problem.
However, for this long centipede, every wheel must have power, which means that the transmission shaft has been extended all the time. In this way, there is a new problem, which is the lag of the transmission system. , The more backwards, the more lagging behind. Therefore, when the car is moving forward, the tires behind will always drag its legs, and the long drive shaft will also lose power, so the electric motor is used again.
The engine on the car is only used to generate electricity. In this way, there is no need for any transmission system. The energy is directly transmitted by the cable. The electric motor of each wheel and the electric motor also have an outstanding feature, which is the large torque. In this way, the starting is Quite fast, as long as you have driven an electric car, you will know that it is easy for the electric motor to beat the internal combustion engine in the start.
However, this kind of electric transmission scheme is still new after all, so problems are frequent. This is not because the technology of the MASS factory is not strong enough, but because the problem is very difficult.
These words of Qin Guan encouraged them, but it always sounded wrong.
"If you feel that there are any technical problems that cannot be overcome, it is better for us to solve them together." Qin Guan said: "You know, we have our own advantages, our processing accuracy is higher, our electronic equipment is more advanced, if we If we develop together, maybe it can greatly improve the performance of this kind of vehicle, and even reach the level of unmanned driving."
What Qin Guan said is not a joke. This kind of car is an electric car. On an electric car, it is the easiest to realize unmanned driving. The steering system, etc., are all driven by electric motors. In this way, as long as you have a qualified program Up.
At present, Han Guo is engaged in research and development in this area to ensure that it takes the commanding heights of every vehicle advancement and follows the way of others, leaving others nowhere to go. Qin Guan is very serious.
Now that they have a cooperative project with them, for example, the long-range rockets have been negotiated. Then, for this chassis, Han Guo will join in, and that is logical.
Seeing that the other party was still hesitating, Qin Guan beckoned to Heribala, "Say it."
Heribala certainly knows more about specific technical issues than Qin Guan. When Qin Guan led people in secret activities just now, Heribala was here to see the car. Now, he has seen it. Many doorways.
I think the biggest problem with this car is that it’s not smart enough.
Heribala said:
When I step on the switch, all the wheels are turning. There is no problem in normal times. However, once encountered Unexpectedly, such as when a wheel is idling, there is some waste. This car should be equipped with a power distribution system."
Power distribution system? Musta looked at Heribala seriously, and what he said happened to hit their point.
Needless to say, the wheels are idling, even when going uphill, it is obvious that each tire requires different power. The more backwards, the greater the downforce and the greater the power required.
"These need to be controlled by the on-board computer to automatically monitor the running status of these wheels, whether they are idling, how downforce is, etc., and then provide each wheel with the correct energy. For example, if one wheel is idling, then it can be The electric energy is completely cut off and used only by the motor on the other side, so that the car can be driven more easily and out of various special road conditions."
What Heribala said was very reasonable, and they couldn't help but nod their heads. They really needed such a system.
"In addition, it is its motor." Heribala continued: "We can see that it actually uses a conventional layout, except that the drive shaft is removed, and the motor is installed outside the half shaft. If it’s wasted, can we improve it and put the motor inside the hub to turn it into a hub motor. In this way, the underside of the chassis is very tidy and there is no need to worry about collisions when walking through some bad roads."
It was damaged by the impact just now. If it were to go inside the hub, it would naturally be the best.
In fact, this is also the ultimate solution for electric vehicles.
When the electric vehicle first appeared, only the electric motor was used to replace the original engine, and the transmission shaft and the like were retained. Later, the electric motor can be integrated into the rear axle without the transmission shaft, but this is still not optimal The best solution is to change the shape of the motor and integrate it directly into the hub.
In this way, the most space is saved, and there is no need to worry about impact, the inside of the wheel hub is the safest.
In fact, wheel hub motors are nothing new. Don’t talk about the original things. Take the most recent example. Last year, the Island National Keiyu University and the Island Power Company jointly developed an IZA sports car. It uses four external The rotor-type permanent magnet synchronous hub motor, the outer rotor is directly connected to the hub. Now, the islanders have begun to move towards electric vehicles. It can be seen that their research and development of new technologies has always been done as the core. Each motor has a maximum power of 25 kilowatts, a maximum speed of 176 kilometers per hour, and a cruising range of 270 kilometers.
Of course, until 2020, in-wheel motors are constantly being developed, but not many are actually mass-produced because they still have some technical defects compared with traditional vehicles.
