Role of a Differential in a Vehicle's Drivetrain System - Automobile Engineering Interview Question

In the field of Automobile Engineering, the differential plays a crucial role in a vehicle's drivetrain system. The main function of a differential is to allow the wheels to rotate at different speeds while providing power from the engine to the wheels.

When a vehicle takes a turn, the inner wheel travels a shorter distance compared to the outer wheel. This difference in distance is compensated by the differential which allows the wheels to rotate at different speeds. Without a differential, this difference in speed could cause skidding or damage to the tires and drivetrain components.

Overall, the differential helps in maintaining traction, stability, and smooth operation of the vehicle by distributing power evenly between the wheels based on the driving conditions. It is a critical component that contributes to the overall performance and efficiency of the vehicle's drivetrain system.
