Drivetrain

Drivetrain components transfer engine and transmission power to the wheels, encompassing the transmission, driveshaft(s), axles, and differential(s). These systems are implemented in both front-wheel drive, rear-wheel drive, all-wheel drive, and four-wheel drive vehicles. Key features include gear ratios optimized for torque and speed, constant velocity joints enabling angular motion, and differential mechanisms facilitating wheel speed variation during turns. Modern drivetrains increasingly utilize electronically controlled clutches, torque converters, and limited-slip differentials for enhanced performance and stability. Component materials range from high-strength steel alloys to lightweight composites, depending on application and performance requirements.
