Abstract

The invention relates to a variable speed fan drive (10) . There is a need for a variable speed fan drive (10) with fewer seals and bearings, which is operated by system hydraulic pressure, which has fewer parts and which is simpler to assemble. A variable speed fan drive (10) is provided for a vehicle powered by an internal combustion engine. The fan drive has a driver variable sheave unit (12), a driven variable sheave unit (14) and a belt (69) engaging both the driver and driven variable sheave units (12, 14). The driver variable sheave unit (12) includes a driver shaft (24) drivingly coupled to an engine output shaft (16), a first axially fixed half sheave (30) mounted for rotation with the driver shaft (24), and a first axially movable half sheave (40) member mounted for rotation with the driver shaft (24) and movable axially on the driver shaft (40). The first axially movable half sheave member (30) includes a belt engaging flange (44) formed integrally with an axially movable piston member mounted for rotation with the driver shaft (24) and movable axially in response to hydraulic pressure.
