A drive shaft is a rod-like component that transmits torque from your vehicle's engine to the wheels. It's essentially the shaft that drives your vehicle. The driveshaft transmits torque at varying angles between driveline components
A drive shaft is a vehicle component for transmitting mechanical power and torque and rotation, 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.
As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia.
