Title:
LEVITATING BICYCLE HUB COUPLING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/066154
Kind Code:
A1
Abstract:
The present invention relates to a levitating bicycle hub coupling structure and, more specifically, to a levitating bicycle hub coupling structure, in a bicycle hub structure, which: uses magnets so as to upgrade an inner contact structure into a levitating noncontact structure, thereby reducing friction; enables the position of a hub inner shaft member for transmitting the load of a user to an inner bearing part and the like to be changed to an upper or lower preset position, and fixes the same at a changed position so as to offset the load applied to the shaft member by the repulsive force of the magnets, such that the load is not applied to the bearing parts positioned at both sides of the shaft member or is significantly reduced so as to improve rolling performance, and thus riding of the bicycle becomes smoother and easier; or has first and second inner magnet parts formed at the outer peripheries of both sides of the housing rotating by being connected to bicycle wheels, and has first and second outer magnet parts corresponding to the first and second inner magnet parts so as to generate repulsive force, such that when the user gets on the bicycle, an eccentric load transmitted to the shaft member through a bicycle frame is borne by the repulsive force, thereby enabling the load applied to the bearing parts to be prevented.
