The Function of a Driveshaft

The basic function of a driveshaft is to transmit power from one point to another in a smooth and continuous action. In automobiles, trucks, and construction equipment, the drive shaft is designed to send torque through an angle from the transmission to the axle. 

The drive shaft must operate through constantly changing relative angles between the Input shaft and the Output shaft, it must also be capable of changing length while transmitting torque.
The axle of a vehicle is not attached directly to the frame, but rides suspended springs in an irregular, floating motion. This means the drive shaft must be able to expand, contract and change operating angles when going over bumps or depressions. This is accomplished through Universal Joints (U-Joints) which permit the drive shaft to operate at different angles, and Slip Joints, which permit contraction and expansion to take place. 

The Double Cardan constant velocity type U-Joint is a special designed to accommodate necessary angles not compatible with Single Cardan U-Joints the CV joint also requires special attention.

Neglect is the main enemy. Remember, Grease is the life-blood of the drive shaft.
