drive shaft

الوصف

The drive shaft is anassembly of one or two Universal joints connected to a shaft or tube used to transmit power from the transmission to the differential. It is also called the propeller shaft.
On front engined rear-wheel-drive cars, the rotary motion of the transmissions output shaft is carried through the drive shaft to the differential, which causes the rear drive wheels to turn.
The drive shaftis normally made from seamless steel or aluminum tubing with Universaljoint yokes welded to both ends of the shaft. To save weight, some manufacturers useepoxy-and-carbon fiber shafts. Some drive lines have two drive shafts and three Universal jointsand use a center support bearing that serves as the connecting link between the two halves
