The driveshaft is a crucial component in an automotive transmission system, transmitting power. Working in conjunction with the gearbox and differential, the driveshaft 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 a universal joint 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.
