Patent ID: 8418582

Claim:
A flywheel assembly for exercise devices, comprising: a flywheel adapted to be rotatably mounted on an exercise device and having a trough centrally defined therein; a magnetic control device received in the trough for providing damping to the flywheel, wherein the flywheel is rotatable relative to the magnetic control device, the magnetic control device including: a first disc and a second disc securely mounted to each other, the first disc and the second disc respectively having a first protrusion and a second protrusion eccentrically and inwardly extending from the first disc and the second disc, the first protrusion and the second protrusion respectively having a center, wherein the two centers and a center of the flywheel are collinear, a slot defined in the second disc and a first curved cavity defined in an interior of the second disc for partially receiving a resilient member, a first stopper extending from one end of a bottom of the first curved cavity for abutting a first end of the resilient member; and a first wiggle seat and a second wiggle seat respectively laterally and rotatably mounted on the first protrusion and the second protrusion, wherein the first wiggle seat and the second wiggle seat are synchronously pivotally moved relative to the first protrusion and the second protrusion when being operated, each wiggle seat having a through hole defined therein such that the first protrusion is pivotally received in the through hole in the first wiggle seat and the second protrusion is pivotally received in the through hole in the second wiggle seat, the first wiggle seat and the second wiggle seat respectively formed with a first sector shoe and a second sector shoe, wherein each sector shoe includes a periphery having multiple magnets secured thereon for providing damping to the flywheel, a second curved cavity defined in the second sector shoe and communicating with the first curved cavity for receiving the resilient member, a second stopper extending from one end of a bottom of the second curved cavity for abutting against a second end of the resilient member; an axle unit centrally extending through the flywheel and the magnetic control device for positioning the flywheel and the magnetic control device on the exercise device, wherein one end of the axle unit is securely connected to the second disc such that the flywheel is rotatable relative to the magnetic control device; and a cable having a first end secured on the first disc and a second end adapted to be connected to a lever for user to operate the magnetic control device and adjust the damping that is acted on the flywheel.
