Abstract
A resistance unit for an exercise device includes a resistance mechanism, such as a fluid-type resistance mechanism, located within a housing. A rotatable shaft is interconnected with an input member. An input roller is engaged with the shaft, and is adapted for rotation in response to a force exerted by a person during exercise, such as rotation of a bicycle wheel. The resistance mechanism imparts resistance through rotation of the shaft, which results in resistance to the external force, such as rotation of the bicycle wheel. A combination fan/flywheel member is mounted to the shaft. The combination fan/flywheel member maintains inertia of the rotating shaft, and includes blade structure which directs air toward the housing of the resistance mechanism upon rotation of the combination fan/flywheel member along with the shaft. The combination fan/flywheel member includes a series of radially spaced blades which extend between and interconnect an inner hub section and an outer ring section defined by the combination fan/flywheel member. The housing of the resistance mechanism is constructed so as to present spaced cooling fins facing the combination fan/flywheel member, to facilitat…
