Abstract
A fan drive system is provided having a housing connected with a pulley. A fan shaft is rotatably mounted to the housing by a clutch. A piston actuates the clutch. A pressure tube is provided for delivering pressure to the piston. A valve controls pressure against the piston. A fixed shaft rotatably supports the housing and the pulley and has passages extending through the pulley. A base connects the support shaft to a vehicle structure. An oil plate has inlets and outlets with the shaft passages. The oil plate circulates the hydraulic fluid. A coolant plate is juxtaposed between the oil plate and the structure supporting the support shaft. The coolant plate has inlets and outlets for coolant from a remote cooler.
