New description: [New technology of the jaw] This creation is about the unilateral displacement of the flower hub ratchet structure, especially to reduce the frictional resistance, making the kinematic and tooth removal movements faster, smoother and more effective. A ratchet structure that enhances the efficiency of the transmission. [Prior Art] The structure of the bicycle hub is mainly composed of a hub seat, a shaft rod, a rotating group, a toothed disc and the like to provide the positioning of the axle and the smooth rotation of the rim, and may also be adapted according to the shifting requirements. Further, a sleeve and an obscuring device are added. If the transmission is differentiated, the hub structure can be further zoned 77: the two-way type of the directional and the two-way type can only be rotated by a single = direction, and the transmission direction is usually the direction of the bicycle, reverse 丄The idling state; the two-way type refers to the forward and reverse rotation of the hub:: system:::: the one-way rim with ratchet structure, the ratchet is engaged, wherein the scale σ σ is different, roughly divided For the radial clamping and the shaft extending the protruding teeth, and the ratchet is made, the ratchet block of the ratcheting and retaining of the two-way clamping of the ratcheting of the wheel hub is driven by the axial direction. The ratchet seat and the X-seat axially extend the convex teeth and cooperate with the shaft #. Α to drive. Wherein the axially clamped single ratchet seat will produce a peak type 11 type of wheel structure, when the hub seat and the seat are relatively linearly displaced from the disengaged state, and a gap of 3 M420445 is generated to achieve the tooth removal action. In the idling state of the non-transmission, the linear displacement actuation mode between the two sides of the trough seat and the hub seat and the sleeve seat is recorded, and is divided into two types: a bilateral linear displacement and a unilateral linear displacement.

In addition, the unilateral linear displacement bicycle wheel has a ratchet structure, such as the "flower hub ratchet device" disclosed in the Japanese Patent No. 096219287, which includes: a set of rings made of magnetically conductive metal. The ring of the ring is changed to the inner circumference. 4 M420445 is provided with a plurality of teeth arranged in a ring shape centered on the axis, each of which has an axial extension; a ratchet block is made of a magnetically conductive metal. The annular block of the end face has an annular outer peripheral wall that is axially displaceable to match the latching teeth, and one side annular ratchet is provided on one end surface of the ratchet block; the one side annular ratchet is set on a flywheel The end surface of the device is unidirectionally engaged with the lateral annular ratchet of the ratchet block; one or more permanent magnets are disposed on the end surface of the ratchet block without the lateral annular ratchet. [Creation content] (Technical problem to be solved) In the above structure, the former is provided with a screw ring on the right side of the hub body, and the plurality of teeth are arranged in a radial opposite ring between the screw ring and the one-toothed disk. For mutual meshing positioning and relative linear displacement, the rotor and the other toothed disc are also provided with a plurality of teeth in a radial opposite ring for mutual meshing positioning and relative linear displacement to form a bilateral linear displacement mode. a plurality of teeth that are in mesh with each other and have a slope shape, and the spiral ring cooperates with the two-toothed disc and an magazine to form a free wheel mechanism, and the The tooth type disc has the effect of bilateral linear displacement actuation. When the front tooth is moved forward, the teeth between the two-tooth type discs push each other to generate a transmission effect, and when the reverse backward movement, the tooth side slope side The two-toothed discs are separated from each other and idling, and the latter structure is integrally formed on the inner end surface of the flywheel device. Lateral annular ratchet And the ratchet block is mounted toward the flywheel 5 M420445 - the end is provided with a side annular ratchet, which is engaged with the end face of the flywheel device, and the ratchet block is normally placed in the collar by the action of the permanent magnet, the ratchet block can be The linear displacement is relative to the collar, and the lateral annular ratchet of the other flywheel device is fixed, so that a linear displacement mode between the ratchet block and the flower hub is formed, and the one-way coupling transmission and the reverse are also achieved. The effect of idling to the tooth removal. However, the former two conventionally engage the ratchet teeth, the teeth are all sloped, φ each of the tooth surfaces is adjacent to a vertical plane of the other side by a slope, so that the teeth have a preset height, and the other There is a certain height difference between the teeth. During the linear operation of the toothed disc or the ratchet block, the contact area of the inclined surface of each tooth is large, and no gap can be generated, which is easy to cause wear and excessive friction. The speed of linear movement of the toothed disc and the ratchet block is slowed, and the vertical surface of each of the teeth is different from the height, so that the ratchet wheel is not smooth when it is actuated, and the reset meshing action of the toothed disc and the ratchet block is affected. Moreover, the sensitivity of the ratchet structure is deteriorated, and the ratchet conduction benefit is affected; further, in the ratchet structure of the single-sided linear displacement, the flywheel device is integrally provided with a lateral annular ratchet, which is difficult to form.
