The driveshaft is a crucial component in a car's drivetrain, responsible for transmitting power. Together with the gearbox and drive axle, it transfers power from the engine to the wheels, providing the vehicle with traction.
The driveshaft, along with the transmission and differential, transmits engine torque to the wheels, propelling the vehicle.
Driveshafts are used to connect two shafts that are not on the same straight line, typically in conjunction with universal joints to accommodate changes in angle. For example, in independent and non-independent suspensions, the shaft connecting the transmission output shaft and the final drive input shaft is generally called the main driveshaft; in independent suspensions, the shaft connecting the differential output shaft and the drive wheels is generally called the half-shaft.
