What is differential?

Question

Accepted Answer

Differential is a mechanical device that allows the wheels of a vehicle to rotate at different speeds.

Differential is commonly found in vehicles with multiple wheels, such as cars and trucks.
It is located in the center of the axle and connects the drive shaft to the wheels.
The main purpose of a differential is to allow the wheels to rotate at different speeds while still receiving power from the engine.
This is important when turning corners, as the outer wheel needs to travel a greater distance than the inner wheel.
The differential achieves this by using a set of gears that distribute torque to the wheels based on their rotational speed.
For example, when making a left turn, the right wheel needs to rotate faster than the left wheel, and the differential allows for this speed difference.
Differentials can also be found in other mechanical systems, such as in industrial machinery and robotics.

Accepted Answer

The differential is a set of gears that transmits engine power to the wheels, while allowing them to turn at different speeds on turns. With rear-wheel-drive (RWD), the differential is between the rear wheels, connected to the transmission by a driveshaft.
