ABSTRACT:
A differential having a housing for receiving differential components. An input shaft, for example a drive pinion gear, is rotatably mounted within the differential housing. A drive line connection point is affixed to the drive pinion gear and is the mounting point for the drive shaft. A fan is disposed on the drive line connection point and is used to force air over the differential housing. The fan may be formed integrally with a drive train part, or be separable therefrom. Rotation of the fan forces air over the surface of the differential housing causing forced convection cooling of the differential components.
