ABSTRACT:
A clutch assembly (20) for a fan drive system (12) of an engine (14) includes a translatable clutch housing (30) that is coupled to a fan (16). A rotating shaft (27) has a non-grooved thermal energy transfer portion (28) that is coupled to a drive pulley (32) of the engine (14). A liner (34) resides between and is engageable with the rotating shaft (27) and the translatable clutch housing (30). The engagement thereof generates thermal energy. The non-grooved thermal energy transfer portion (28) has a cross-sectional thickness (T1) of approximately less than 11 mm and transfers a significant portion of the thermal energy to the drive pulley (32).
