The drivetrain is a crucial system in vehicles that transmits power from the engine to the wheels. Key components include the transmission, which adjusts the engine's power and speed, and the driveshaft, which transfers this power to the wheels. Other important parts are the differential, which allows wheels to rotate at different speeds, and the axles, which support the vehicle's weight and enable wheel movement. In addition to these components, the drivetrain also includes the clutch or torque converter, which helps engage and disengage the engine from the transmission. Proper functioning of these parts ensures smooth acceleration and efficient power delivery, contributing to overall vehicle performance.
