Driving Shaft is a mechanical component for transmitting torque and rotation. Also for connecting other components of a drive train that cannot connect directly because of distance. And the need to allow for relative movement between them.
The Driving Shaft (also called propeller shaft or prop shaft) is a component of the drive train in a vehicle, with the purpose of delivering torque from the transmission to the differential, which then transmits this torque to the wheels in order to move the vehicle. Drive shafts are also responsible for directing power to the wheels.
