A differential is a mechanical device that transmits rotational motion from one shaft to another, while also allowing for a difference in speed between the two shafts.
A differential uses a set of gears to allow for different rotational speeds between the two shafts. When one shaft is rotating faster than the other, the gears inside the differential adjust to allow for the difference in speed.
The main components of a differential include the ring gear, pinion gear, spider gears, and differential case. The ring gear is connected to the drive shaft, while the pinion gear is connected to the ring gear. The spider gears are located between the ring and pinion gears, and the differential case holds all the gears in place.
There are several types of differentials, including open differentials, limited slip differentials, locking differentials, and electronic differentials. Each type has its own unique design and function, but they all serve the same purpose of allowing for different rotational speeds between two shafts.
Some common signs that your differential may need to be serviced include strange noises coming from the differential, difficulty turning or steering, and leaking fluid. It is important to regularly check and maintain your differential to ensure proper functioning and prevent any potential issues.
