New Description: [New Technology Field] This creation department is about a "bike 彳b hub ratchet structure", especially when it is installed at the wheel hub of a bicycle for users to step on. When the wheel is rotated without stepping on it, it can be automatically separated, so that the wheel and the flower hub can drive the pedal to follow the rotator when it is not idling. [Prior Art] According to the bicycle wheel hub structure of the 4th and 10th, as shown in the eighth, ninth and tenth figures, it is fixed at the center of an it* hub (ίο) The shaft (11) is recessed with a receiving groove (1〇1) at one side, and a bearing (12) is disposed in the receiving groove (101) and a ratchet seat (13) is locked, and the ratchet seat ( 13) ® has an inner perforation (131) in the center for sequentially receiving a guiding sleeve (14), a magazine (15), and meshing with a movable ratchet (16), and a movable ratchet (16) The upper system is provided with ratchet teeth (161), and the outer side is provided with a suitable portion, and a toothed disc binding seat (18) and a fixed ratchet wheel (17) are sequentially arranged from the outer side to the inner side. (18) The hub (1〇) is separately rotatable, the outer side is provided with a toothed disc, and the fixed ratchet (17) is fixedly coupled with the chainring joint (18), and it is active Ratchets (171) are also provided on opposite sides of the ratchet (16) for engaging the movable ratchet (16). With the use of the above structure, when the user steps on the pedal and indirectly drives the sprocket coupling (18) to rotate, the movable ratchet (16) and the ratchet (161) on the fixed ratchet (17) are 171) biting each other and causing the ratchet seat (13) to be driven to push the flower hub (1〇) and its wheels to rotate, so that the bicycle can travel forward, and if the user does not step on the pedal, the toothed disc When not rotating, or when the downhill bicycle is rapidly sliding, the ratchet (161) on the movable ratchet (16) will push against the ratchet (171) on the fixed ratchet (17), and the impeller will be pushed by the thrust ( 15) Compression, and the ratchet (161) - a ratchet (171) over the fixed ratchet (17) is used to achieve a state transition between the wheel and the toothed disc and the automatic separation of the non-stepping. However, the above-mentioned conventional structure still has the following problems in practical applications. (1) Since the movable ratchet (16) and the fixed ratchet (Π) are attached to the opposite side of the ratchet (161) (171) The bite is combined to achieve the state transition between the wheel and the toothed disc and the automatic separation of the non-stepping. However, the 5 M304484 ratchet (i6i) (m) on the opposite side is engaged, not only because the contact surface is small, but also the power Can not be surely transmitted, because the force of the action is concentrated on the small contact surface, and the ratchet (161) 〇 71) has a tendency to collapse; (2) when it is activated, the system uses the sprocket joint (10) Rotating 'make the movable ratchet (10) and the ratchet teeth 61 (171) on the fixed ratchet (9), and then rotate the flower (10) and its wheel with the ratchet seat (10), but because the flower hub ratchet structure is composed of components Fresh, so the group scales are boring, production and material costs are also higher; (3) its live female wheel (10) and gj fixed ratchet (9) with the ratchet on the opposite side, to achieve the wheel and the pedal combination It does not step on the automatic separation and converts, so it will be annoying when used. (4) The sound is fine) When it is used for a long time, and when it is elastic and tired, it is impossible to push the live _ wheel ((6), and the phenomenon that the action is not true is generated. The lack of the above-mentioned bicycle bicycle recording wheel structure is the idea of thinking and creation. It has been designed with many years of experience. After many trials and trials, the sample test, and many corrections and improvements, is the creation of this creation. [New content] The technical problem to be solved is that the ratchet structure of the face-lifting flower hub is engaged by the ratchet on the opposite side, not only because of the contact ratchet, but also because of the force of the action, the focus is on the small contact. On the face, and let the caries have easy _ 虞, this is the technical problem to solve. The technical characteristics of the problem: Cheng, the soil secret "(four) know the upper system combined with - ratchet, the ratchet is accommodated There are on-axis system =::::=: death::: free rotation ~· fixed groove, the outer circumference can be used for the wheel to be fixed, so that the car has 5 ratchets, so that the hybrid can be placed on the spine Toothed teeth _, and can be driven by the sprocket joint, the sprocket joints provide teeth In combination, the inner t is set == month, 1 M304484 'because the 'sprocket joint itself will also rotate, so that a self-lubricating bearing is used as a pivot at the central perforation of the toothed disc joint, and the self-lubricating bearing is located It can also be used with a bushing to avoid direct contact between the self-lubricating bearing and the metal mandrel. The self-lubricating bearing has self-lubricating, wear-resistant, light weight, thin wall design and high load. The material characteristics are matched with the aperture of the central perforation of the toothed disc coupling seat, and the center has a matching hole and a bushing, and one end of the bracket is convexly provided with a limiting flange, and the length of the self-lubricating bearing is directly matched with The length of the sprocket joint is set, and the above structure is used to obtain the ratchet structure of the bicycle hub. Compared with the effect of the prior art: (1) This creation provides a bicycle hub ratchet structure, which uses the roller to cooperate with the ratchet. Not only can the contact surface be enlarged, the power can be transmitted reliably, but also because the force of the action is evenly dispersed on the ratchets of the large contact surface, and the ratchet is not easily collapsed. (2) The creation provides a bicycle flower hub ratchet structure, which only needs to engage the roller between the ratchet and the groove surface of the matching groove, which can smoothly drive the flower and its wheel rotation, so the structure not only constitutes The number of components is small, relatively simple and quick to assemble, and because of the small number of components, the production and material costs will be reduced. (2) This creation provides a bicycle flower hub ratchet structure, which uses the roller to cooperate with the ratchet. If it is not Φ, it will produce annoying sound, and it is relatively quiet when riding. (4) The creation provides a ratchet structure of the bicycle flower hub, which does not need to be pushed by the magazine, that is, it can achieve the effect of stepping on the road and not automatically stepping on the pedal, so that the relatively inelastic fatigue is caused by the phenomenon of inaccurate actuation.
