Drive Shaft

What is Drive Shaft?

A drive shaft is a most important part of a vehicle that transfers torque from the transmission to the differential, and then the differential delivers this torque to the front wheels to run the vehicle. The drive shaft is also known as a Cardan shaft, propeller shaft, or prop shaft.

In simple words, the main function of the propeller or drive shaft is to deliver the engine torque from the differential to the vehicle wheel.

The position of the driveshaft changes according to the car model and configurations of the car front-wheel drive, four-wheel drive, and front-engine rear-drive. Many other vehicles such as boats, locomotives, motorcycles, trucks, and vans also have prop shafts.

These shafts have a different number of prismatic joints, leaf joints, universal joints, or jaw couplings to enable change in distance and alignment between drive and driving parts.
