Abstract:
Some embodiments of a fan clutch system may drive an output member to rotate at a first speed when opposing friction clutch surfaces are engaged and to rotate at a second, slower speed when the friction clutch surfaces are shifted to a disengaged position. In particular embodiments, the multi-speed clutch system may employ an eddy current drive system that is arranged axially rearward of the friction clutch surfaces while the fan blade device is mounted in a position that is axially forward of the of the friction clutch surfaces.
