  • Patent number: 11679837
    Abstract: An integrally formed bearing free pedal includes a central axle and a pedal body. The pedal body has a rotation axis, and is provided with an axle bore formed along the rotation axis. The central axle has an installation portion and an opposite combination portion. The central axle and the pedal body are integrally molded. The combination portion is disposed in the axle bore. A rotation gap is formed between the periphery of the central axle and the axle bore, so as to allow the central axle to rotate with respect to the pedal body along the rotation axis. Thus, the pedal has no bearings and other related components, so as to be structurally simple, and the manufacturing cost is reduced.

  • Patent number: 8875862
    Abstract: A ratchet hub using a magnetic force for restoration as disclosed has a freewheel unit and a ratchet ring thereof forming a unidirectional ratchet mechanism and a magnetic assembly using a magnetically repulsive force to normally make the freewheel unit and ratchet ring engage mutually and allow force transmission therebetween. Once a force disengaging the freewheel unit from the ratchet ring surpasses the magnetically repulsive force, the ratchet ring is pushed away from the freewheel unit. When the force disengaging the freewheel unit from the ratchet ring disappears, the magnetically repulsive force automatically and promptly returns the ratchet ring to engage with the freewheel unit again.

    Abstract: A bicycle hub assembly includes a hub body mounted around an axial core. The hub body has one end containing a ratchet ring that has an inner periphery formed with unidirectional ratchet teeth. A ratchet wheel is arranged between the axial core and the ratchet ring and has an outer periphery formed with detent recesses, each said detent recess receiving therein a detent for engaging with the ratchet teeth. The detent includes a pivot portion and a swinging arm. The pivot portion is retained by the detent recess and has an arc of 180 to 270 degrees so that the swinging arm swings when the pivot portion rotates in the detent recess. The detent has clenching surfaces for engaging with the ratchet teeth, wherein a direction where the clenching surface extends is identical to a swinging direction of the swinging arm.
