Diesel Truck Fan Clutches to Meet the Energy and Environmental Challenges 740598

This paper discusses bearing arrangements designed to maximize stability and load capacity within available envelope dimensions. Also presented is a means of negating the detrimental effects of cylinder reactions in a pneumatic clutch, while at the same time increasing the torque-to-space ratio. These concepts were realized during a study expressly intended to view the various design elements with the requirements of a diesel truck fan clutch in mind.Further, the study resulted in the development of a nonmodulating, direct acting thermal control valve, specifically engineered to complement the action of a pneumatic fan clutch as part of an overall temperature controlling system.
