Super Weapon Swap System

Finally, the power control box was repaired, and musta breathed a long sigh.

"How about doing it well?" at this time, Qin Guan and others have come out. Qin Guan is interested in visiting such a broken factory, which makes musta a little strange and thankful. Fortunately, the other party is not watching, otherwise it is not easy to eliminate the fault.

"Yes, it's fixed," said musta.

"Although the technical route of this kind of electric drive vehicle has been available for a long time, it has not been mature for a long time. Therefore, it is common for this kind of vehicle to break down halfway in case of problems. Don't have psychological pressure," Qin Guan said.

Qin Guan said that musta's face was hot and felt normal.

At that time, Hans developed a Tiger tank weighing more than 50 tons. At that time, a group of doctors at Porsche had an electric drive plan, using an internal combustion engine to generate electricity, and then using an electric motor to drive the track to rotate.

What are the advantages?

Nature is to solve the problem of high power power transmission. The heavier the tank, the stronger the power it needs. For the transmission system, it is a severe test. After all, the engine of the tank is not always kept at a speed, it is changing at all times. According to the different roads, the throttle at the foot of the engine is also different, and the load of the transmission system is very heavy. At that time, it might be a problem.

However, later, the electric drive scheme was still not passed. Apart from others, the heat dissipation problem alone was not easy to solve, and the motor was often burned.

Later, with the continuous improvement of the power system, the transmission system has stabilized. Now, the transmission system with more than 1000 horsepower is not a big problem.

However, for this long centipede, there must be power on each wheel, which means that the transmission shaft has been rising all the time. In this way, there is a new problem, that is, the lag of the transmission system. The more backward it is, the more lag it will be. Therefore, in the process of moving forward, the rear tires always lag behind, and the long transmission shaft will also lose power, Therefore, the 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 cables to the motor of each wheel. The motor also has a prominent feature, that is, the torque is large. In this way, the start is quite rapid. As long as you drive an electric car, you can know, to say, overtake, It is easy for an electric motor to outperform an internal combustion engine in starting.

However, this electric transmission scheme is still fresh after all. Therefore, problems are frequent. This is not because the technology of Mars factory is not strong enough, but because this problem is very difficult.

Qin Guan's words encourage them, but they always sound wrong.

"If you think there are any technical problems that cannot be overcome, let's solve them together," Qin Guan said "You know, we have our own advantages. Our processing accuracy is higher and our electronic equipment is more advanced. If we work together to develop it, we may be able to greatly improve the performance of this vehicle and even reach the level of driverless."

Qin Guan is not joking. This kind of car is an electric car. On the electric car, it is easiest to realize driverless. The steering system is driven by the motor. In this way, as long as you have qualified procedures.

Now, the state of Han is engaged in research and development in this area to ensure that it occupies the commanding heights of every vehicle progress, takes other people's road and makes others have no way to go. Qin Guan is very serious.

Now, we have cooperation projects with them, such as long-range rockets. It is natural for Han to join in for this chassis.

Seeing that the other party didn't speak and was still hesitating, Qin Guan waved to he ribala: "tell me."

He ribala must know more about specific technical problems than Qin Guan. He ribala was here to watch the car when Qin Guan took people in secret activities. Now, he has seen a lot of doorways.

"I think the biggest problem with this car is that it is not intelligent enough." he ribala said: "when I step on the switch, all the wheels are rotating. There is no problem in normal times. However, once there is an accident, such as a wheel idling, it will be a waste. This car should be equipped with a power distribution system."

Power distribution system? Musta looked at he ribala seriously. What he said just hit the point.

Needless to say, the wheels spin idly. Even when going uphill, it is obvious that each tire needs different power. The more backward, the greater the downward pressure, the greater the power required.

"These need to be controlled by the on-board computer to automatically monitor the operation status of these wheels, whether they are idling, how the downforce is, etc., and then provide correct energy for each wheel. For example, if one wheel is idling, the electric energy can be completely cut off and only used by the motor on the other side to drive the car to start more easily and get rid of various special conditions Special road conditions. "

What he ribala said was very reasonable. They couldn't help nodding. They really need such a system.

"In addition, it's its motor." he zhibala continued: "We can see that it actually adopts the conventional layout. It just removes the transmission shaft and sets the motor outside the half shaft, which is too wasteful. Can we improve it and turn the motor into a hub motor. In this way, the underside of the chassis is very neat, and there is no need to worry about collision when walking through some bad roads."

It was just damaged by impact. If you go inside the wheel hub, it is naturally the best.

In fact, this is also the ultimate solution for electric vehicles.

When the electric vehicle just appeared, it only used the motor to replace the original engine, and the transmission shaft and so on were retained. Later, the motor can be integrated into the rear axle without the transmission shaft, but this is still not the optimal scheme. The best scheme is to change the shape of the motor and directly integrate it into the wheel hub.

In this way, the most space saving, and there is no need to worry about impact. It is the safest in the hub.

In fact, the wheel hub motor is not a new thing. Let's not mention the original things. Take the recent one. Last year, the Island National Day yingyishu University and the island power company jointly developed an IZA sports car. It uses four external rotor permanent magnet synchronous wheel motors, and the external rotor is directly connected with the wheel 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. The maximum power of each motor of this car is 25 kW, the maximum speed is 176 km / h and the range is 270 km.

Of course, until 2020, the hub motor has been continuously developed, but there is not much real mass production because it still has some technical defects compared with traditional vehicles.
