Components of 4WDS
The main components of the Four Wheel Drive vehicles are the two differentials, one in the front and other on the rear axle and a transfer case. Part time 4WD systems have locking hubs in addition to these components. Both types of 4WDs have advanced electronics which help manage the systems with better traction handling.
Differentials : There are two differentials, one is the front differential and the other is the rear differential. The main function of the differentials is to transfer the torque from the drive shaft to drive wheels.
Transfer Case : This component is responsible for spliting the power between rear and the front axels in 4WD systems. The transfer case in a part time 4WD systems locks the rear axle to the front axel drive shaft so that both move at the same speed when four wheel drive is required.
