A mechanical component for transmitting torque and rotation which is usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. Driveshafts are carrier of torque, they are subjected to torsion and shear stress equivalent to the difference between the input torque and the load. To allow for variations in the alignment and distance between driving and driven components, drive shafts incorporates one or more universal joints, jaw coupling, or rag joints and a splined joint or prismatic joint.
A driveshaft connecting gearbox to a rear differential is called a propeller shaft. In the British term, drive shaft is restricted to a transverse shaft that transmit power to the wheels.
