What is the function of differential in a vehicle?

A differential is a mechanical device that allows the wheels on a vehicle to rotate at different speeds, while still transmitting torque from the engine to the wheels. This is necessary when a vehicle is turning, as the inner and outer wheels must rotate at different speeds to avoid skidding.

Differentials are typically located in the axle of a vehicle, between the wheels. They consist of a set of gears that allow the wheels to rotate independently of each other, while still transmitting torque from the engine.

There are two main types of differentials: open differentials and limited-slip differentials. Open differentials allow the wheels to rotate completely independently of each other, while limited-slip differentials limit the amount of difference in speed between the wheels.

Limited-slip differentials are often used in performance vehicles, as they help to improve traction and handling. By limiting the amount of difference in speed between the wheels, limited-slip differentials help to prevent the wheels from spinning and losing traction.

Differentials are an important part of a vehicle's drivetrain, and they play a vital role in keeping the vehicle moving smoothly and safely.
