What is the differential and the role of the car differential

Speaking of some automotive power parts, I believe everyone will immediately think of clutches and transmissions. However, many of our friends said that they don’t know much about the car differential we talked about today, and they didn’t even listen to it. So, what exactly is a differential, and where the role of a car differential has changed, let’s take a look at everyone’s science.

The automobile differential is mainly composed of left and right half shaft gears, two planetary gears and a gear carrier. Its function is to adjust the speed difference between the left and right wheels. When the car is turning or driving on uneven roads, the existence of the differential can make the left and right wheels roll at different speeds (reasonable torque distribution) to ensure Both sides drive wheels for pure rolling motion.

Don't underestimate its existence. If there is no differential or an abnormality occurs, the wheels will inevitably slide while rolling due to the inconsistent speed of the left and right wheels. It not only accelerates the wear of the tires, but also increases the stress on the axles. In severe cases, it may even cause mechanical damage. The maintenance cost will be very high at that time. Therefore, when the car is turning and the tire slips off, you should check the differential at the repair shop as soon as possible.
