Wheel Drive Shafts Description and Operation Wheels
Wheel drive shafts are flexible assemblies consisting of aninner tripot joint and an outer constant velocity joint connectedby an axle shaft. The inner joint is completely flexible, and canplunge in and out. The outer joint is also flexible, but cannotplunge in and out. These drive axles are used to ...
