Document Type and Number:
WIPO Patent Application WO/2022/244898
Kind Code:
A1
Abstract:
The present invention provides a driving force-enhancing apparatus using magnetic force, the apparatus comprising: a first rotating body mounted to a bicycle crankshaft rotated by a pedal to which force is transferred from a user, the first rotating body rotating together with the crankshaft when the crankshaft rotates; a first magnet unit provided on the circumferential surface of the first rotating body; a second rotating body connected to the crankshaft by a chain and mounted to a rotating shaft that rotates together with the crankshaft when the crankshaft rotates, the second rotating body being mounted to the circumferential surface of the rotating shaft; a second magnet unit provided on the circumferential surface of the second rotating body; and a piston unit including a piston magnet that is provided between the first rotating body and the second rotating body and generates attractive and repulsive forces with respect to the first magnet unit and the second magnet unit, wherein the piston unit, while moving between the first rotating body and the second rotating body by means of the attractive and repulsive forces, generates driving force for rotating the crankshaft connected to the first rotating body.
