Benefits of four-wheel drive

When it comes to four-wheel drive, many people have the impression that it is well controlled, strong grip and necessary in rainy and snowy days. Of course, this is correct. So are we going to buy a four-wheel drive or not? Many people took a fancy to its grip on the land and bought a four-wheel drive. Later, they felt that it was a bit different from their expectations. Because I can't feel it at ordinary times, and it's not rainy and snowy every day, I feel that I have lost money in buying a four-wheel drive.

Four-wheel drive vehicles can face more complicated road conditions. But it's not simple. Four wheels turn together. There is also a problem related to power distribution. Facing different road conditions, the four wheels need different power, which is divided into two parts: front wheel and rear wheel. Regarding the power distribution, this is left to the differential.

What is difference? For example, when the car turns, the distance between the left and right wheels is unnecessary. If the two wheels are at the same speed at this time, it must have slipped, otherwise the car will not turn the corner. With the differential, the speed of the left and right wheels can be different when the car turns. Let the two wheels of a car have different speeds. This is the differential.

But if a car suddenly gets stuck in the mud, it's because there is a differential inside. It is a mechanical structure, so I don't know which wheel you are stuck in because the differential doesn't turn, but the other one keeps turning. What should we do? At this time, it is necessary to install a differential lock on the differential. When a wheel rotates abnormally fast, the differential will not work. In this way, the trapped wheel will have power and the car will come out by itself.

Now when we buy four-wheel drive, we will hear some full-time four-wheel drive and timely four-wheel drive. The name sounds familiar, but I don't know it very well, so what does it mean?

In fact, the meaning of these words can be completely understood according to the literal meaning. Full-time four-wheel drive, as the name implies, is always four wheels. This kind of car is designed according to the serious four-wheel drive, so no matter what kind of road, all four wheels are turning. Part-time four-wheel drive is four-wheel drive and two-wheel drive. We can switch according to our own needs. If you think the two-wheel drive is not working, go to the four-wheel drive. Timely four-wheel drive, the difference between it and time-sharing is a word "suitable". The car automatically adapts to the road conditions and switches to four-wheel drive if it feels bad.
