Differential is an ingenious mechanical structure, it can be the driving force of the same size assigned to two different shaft rotation speed, which can make the two shaft speed is not the same.
After arrangement in the front drive axle or drive axle differential, respectively called differential before or after the differential, differential between both are round.
If it is decorated in the middle of the four-wheel drive car on the drive shaft, used to adjust between front and rear wheel rotational speed, it is called a central differential.
Car when turning the wheel track is circular, if the car turning to the right, at the same time, the left side of the left wheel curve is longer than the right side of the wheel, and vice versa.
Hurry up in order to balance the difference, is on the left side of the wheel, the wheels on the right side a little more slowly, or it will produce the so-called steering interference phenomenon, make the vehicle steering difficult, like stepping on the brake at the same time, therefore also calls the steering brake phenomenon.
The driving wheel due to the left and right sides of the wheel are independent of each other, so there is no interference phenomenon.
But on either side of the drive axle wheel if the rigid connection, a shaft with two wheels in the same rotation speed degree, when the vehicle steering, steering interference phenomenon will occur.
In order to make the drive wheels on both sides of the wheel speed can be different, people invented differential.
It can be allowed on either side of the driving wheel running at different speed.
But also because of this characteristic, if a half shaft on the wheel slip, or a half shaft driving force is zero, because the differential has guaranteed the role of two shaft driving force is equal, don't slip on the drive wheels of the driving force will be zero.
This kind of result is that the car is still cannot escape from the dilemma.
At this time no matter how to step on the accelerator can make the car forward, only ideas in skid wheels under the pad dry soil, gravel, branches, hay, increase skid wheels driving resistance force, will make differential driving force redistribution, in order to make the car out of the woods yet.
