Which components are included in the drivetrain?

The drivetrain of a vehicle encompasses the components that are involved in transferring power from the engine to the wheels, allowing the vehicle to move. This includes the transmission, which is responsible for changing and controlling the gears; the driveshaft, which transmits torque from the transmission to the differential; and the differential itself, which allows the wheels to turn at different speeds, particularly useful when turning corners.

These components work together to facilitate the smooth operation of the vehicle, ensuring that the power generated by the engine is effectively delivered to the wheels for propulsion. Understanding the drivetrain is essential for diagnosing and troubleshooting issues related to vehicle movement and performance.

Other components, such as brakes, tires, the battery, starter, fuel pump, and exhaust system, while critical for overall vehicle functionality, do not fall under the drivetrain category as they serve different purposes in the vehicle's operation.
