A front wheel steering mechanism in a center hub steering system. The mechanism comprising an inner wheel hub, an outer wheel hub, paired rolling bearings positioned between these inner and outer wheel hubs, a front shaft, a hub steering bracket attached to outside of the front shaft, and a hub steering shaft. The inner wheel hub is attached to the hub steering bracket so as to freely rotate about the hub steering shaft as an axial center. The outer wheel hub is configured of a left outer wheel hub and a right outer wheel hub. These left and right outer wheel hubs are rigidly coupled or are coupled via a plurality of wire spokes to a rim.

A levitating bicycle hub coupling structure using a magnet in the internal contact structure is provided. The levitating bicycle hub coupling structure in which a non-contact type structure in a levitated form is provided to reduce friction enables the position of a hub inner shaft member for transmitting the load of a user to an inner bearing part to be changed to an upper or lower preset position, and fixes the shaft member 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.

A wheel with an intelligent suspension system that includes a hub, a rim and a set of spokes with dynamically adjustable spoke lengths. Further included is one or more sensors associated with at least the hub and the rim and a microcontroller unit (MCU) that receives sensory signals from the one or more sensors, and transmits control signals to the set of spokes to dynamically control spoke lengths of the set of spokes.

The invention relates to a hub, in particular for bicycles, comprising an axle on which a hub member and a free-wheel member are rotatably arranged, wherein the hub member and the free-wheel member are coupled to each other by a free-wheel mechanism which is based on a pairing of saw-tooth tooth arrangements, which are engaged with each other, of axially adjacent toothed discs and which thereby forms a rotationally secure connection for one rotation direction between the free-wheel member and the hub member, wherein at least two pairings of cooperating saw-tooth tooth arrangements are provided.

A system for wheel alignment provides an indexable pair of washers in conjunction with a sleeve having non-concentric inner and outer surfaces that allow for adjustments to camber, toe, and thrust. The system can be retrofitted to existing axle systems using a sleeve that fits over the spindle of the axle. Rotation of the sleeve relative to the spindle provides for adjustment to wheel alignment. The indexable washers can be used to determine the precise amount of adjustment and fix the position of the sleeve once adjusted. The system can be implemented regardless of the circumferential position (i.e. azimuthal orientation) of a keyway or groove on the axle spindle that is typically used to lock the position of the axle nut.

The present invention provides a wheel hub for a vehicle, including: a) a wheel axle defining an axis of rotation for the wheel; b) a hub body rotatably coupled to the axle for rotation about the axis of rotation, the hub body defining an internal cavity; and, c) a braking assembly, including: i) at least one first annular plate disposed within the internal cavity about the axle, the at least one first annular plate rotatably fixed with respect to the hub body so as to rotate therewith about the axis of rotation; ii) at least one second annular plate disposed within the internal cavity about the axle and adjacent to the at least one first annular plate, the at least one second annular plate rotatably fixed with respect to the axle, and at least one of the first and second annular plates being slidably movable within at least part of the internal cavity; and, iii) an actuator disposed within the internal cavity and configured in use, to cause an axial load to be applied to the slidably movable plate to thereby cause the at least one first and second annular plates to frictionally engage thereby applying a braking load between the hub body and wheel axle so as to brake the wheel of the vehicle.

A unitized wheelend is provided. The unitized wheelend includes a hub having an inboard side bounded by an oil seal and an outboard side bounded by a retainer releasably coupled to the hub. The unitized wheelend assembly includes an inboard bearing assembly, a spacer, an outboard bearing assembly, and a spindle nut assembly.
