Beschreibung
Zusammenfassung:	A fan assembly may include an input shaft, first and second belts, first and second pulleys engaged by the first belt, third and fourth pulleys engaged by the second belt, output shaft rotationally coupled to a fan, and a clutch assembly. The second pulley may be rotationally coupled to the first pulley via the first belt so as to rotate in the same direction as the first pulley. The fourth pulley may be rotationally coupled to the third pulley via the second belt so as to rotate in the opposite direction of the third pulley. The clutch assembly may be configured to selectively rotationally couple the output shaft to the input shaft via the first pulley, first belt, and second pulley. The clutch assembly may also be configured to selectively rotationally couple the output shaft to the input shaft via the third pulley, second belt, and fourth pulley.
