Title:
空中浮揚式自転車ハブ結合構造
Document Type and Number:
Japanese Patent JP7014465
Kind Code:
B2
Abstract:
The present disclosure relates to a bicycle hub, and more particularly, to a levitating bicycle hub coupling structure using a magnet in the internal contact structure in order to upgrade the levitating non-contact type structure to reduce friction and enable 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 internal 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 external magnet parts corresponding to the first and second internal 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 supported by the repulsive force, thereby enabling the prevention of load being applied to the bearing parts.
