  • Clutchless viscous fan drive wherein input member serves as the body and the cover carries seal
    Patent number: 7044282
    Abstract: A clutchless viscous fan drive system is formed in which the body of the fan drive is attached directly to the input shaft and rotates at full input speed. A seal is pressed into the cover at the output drive and seals against a cast-in seal ring on the body. The fan drive formed does not need a clutch and thus will not trap heat inside the viscous fluid chamber between the body and cover. The body rotates at full input speed with the input shaft and will improve airflow across the body side fins, therein improving fan drive cooling performance.
