Description

  In particular, the present invention relates to a magnetically braked flying wheel apparatus that is economical and uses ergonomics to make use of a simplified and modularized flying wheel technology that carries the required weight.

  Magnetic braking flying wheel devices are widely used in fitness equipment such as runners, exercise bikes, walker, etc., and by adjusting the clearance of magnetic braking flying wheels, the damping adjustment action can be demonstrated in a timely manner to meet the user's needs for exercise. is there.

  FIG. 1 shows a conventional magnetic braking exercise bike, in which a front fork (11) of a motorcycle frame (10) is provided with a flying iron (12) made of cast iron, and the flying wheel (12) is a belt (13 ) Is connected to a power transmission wheel (15) driven by a pedal (14), and a bow-shaped magnetic part (16) covers the outer periphery of the flying wheel (12) of the motorcycle frame (10). The magnet is provided on the inner peripheral surface of the magnetic part (16), and the user adjusts the angle of the magnetic part (16) to gradually approach the distance from the flying wheel (12). Or, by moving away, the distance between the magnetic part (16) and the flying wheel (12) and the magnitude of the magnetic braking force are significantly changed. The motor function is adjusted by the air braking load.

  However, the range in which such a magnetic braking load adjustment is possible is limited, and if it exceeds this range, it is necessary to replace the flying wheel (12) with a different weight to meet the needs of human engineering. Specifically, the optimal weight of the flying wheel (12) is different between males and females, adults and children, or Eastern and Western people, but the conventional “monolithic casting flying wheel” is not available. It is covered with walls and has the following drawbacks.
