Description of the invention: [Technical field of the invention] The invention has a ratcheting structure (2), in particular, a transmission mechanism for a rear wheel of a vehicle, which uses a limiting member to keep the ratchet normally closed In the state, the ratcheting stud and the damper member are in a displacement relationship, that is, the pedal is not driven when the wheel is reversed, and no noise is generated. [Prior Art] 习 The conventional flower recording structure, as shown in Figures 8 and 9, includes: a ratchet disk (60), a flower hub (70) and a mandrel (10), a ratchet The disk (10) is a tubular body, and there are no toothed discs (61) and a ratchet seat (62) on the circumferential surface. The ratchet seat (62) has a plurality of ratchet holes (621) on the circumferential surface thereof. 'There are a plurality of ratchets (10) provided with the ratchet teeth (10) and the ratchet holes (10) are provided with an elastic member ((4), the flower hub (10) is a tubular body, and the side is fastened. a ratchet disk chamber (71), and a ratchet disk chamber (71) is provided with a helical tooth surface (Ή1), a mandrel (8〇) is a cylinder, and the front and rear ends are provided with external threads, wherein the segment ® Appropriate Positioning - Stop Ring (81) 'The ratchet disc (6〇), flower (7〇) and mandrel (8〇) can be set with a plurality of bearings (82) and positioning parts (83), the mandrel (8〇) is fixed in the hub (70) with a bearing (82). The ratchet seat (62) is placed in the ratchet disc chamber (71) of the hub (70). In the actual operation, the ratchet (63) is pushed outward by the elastic member (64), and the normal state remains open and The oblique tooth faces (711) of (70) are in contact with each other, and when the rotating ratchet disk (60) is rotated forward, the ratchet teeth (63) are against the oblique tooth surface (711), so that the ratchet disk (6〇) The hub (70) is driven by the ratchet (63), and when the ratchet (61) is reversed, the ratchet (63) is 200944396 subjected to the helical tooth surface (711) and the elastic member (64). Actuating 'the effect of the pendulum action, and the flower hub (70) is not interlocked by the ratchet (63), and when the flower hub (70) is rotated forward, the ratchet (63) is not affected by the flower hub (70) When the hub (70) is reversed, the ratchet (61) is reversely urged by the helical tooth surface (711) to reverse the ratchet disk (6〇). It is not difficult to find out that there are still some shortcomings in the above-mentioned conventional structure. The main reasons are as follows: (1) When the flower hub (70) is reversed, the ratchet (63) is subjected to a helical tooth surface ( 711) and the elastic member (64) act to produce a reverse swing effect, and the ratchet disc (6〇) is not interlocked with the hub (7〇), when the vehicle is retracted or the pedal is reversed When turning, the friction and arpeggio of the ratchet and the helical tooth surface will be produced. (2) Reverse the flower hub (70) When the ratchet (63) is reversely driven by the oblique tooth surface (711), the ratchet disk (60) is driven to reverse the pedal, so that when the bicycle is used to retreat, the foot pedal is applied. When the bicycle retreats, the rotation of the pedal is easy to accidentally injure the user. When applied to the electric bicycle, the driving motor is connected to the ratchet disc (60), which will cause the electric bicycle to be retracted. The process is quite laborious. In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical. SUMMARY OF THE INVENTION The technical problem to be solved is: 200944396 The flower structure of the conventional knowledge, when the flower is reversed, the ratchet system is reversely pushed by the oblique tooth surface, so that the ratchet disk drives the pedal to reverse Turning, when applied to the bicycle to retreat, the rotation of the pedal is easy to accidentally injure the user, and when applied to the electric bicycle, the driving motor is connected to the ratchet disc, which will cause the electric bicycle to be retracted. It is quite laborious, this is the technical problem to be solved. Technical features for solving the problem: A flower hub ratchet structure (2) comprising: a flower hub, a helical ring, a damper element, a toothed disc member and a mandrel, the connecting rod and The ratchet seat is disposed at two ends of the flower hub, and the ratcheting fulcrum of the ratchet is located in the ratchet shaft hole, the protruding column of the ratchet is facing outward, and the limiting piece is sleeved on the ratchet seat In the limiting slot, the ratchet is positioned in the ratchet opening, the toothed disc member is sleeved on the ring of the flower hub with a sliding portion and a lubricating member is disposed, and the helical ring is disposed on the ratchet and a damper member is sleeved on the connecting portion, and is connected to the stud of the ratchet by the yoke hole, and the elastic piece at the damper hole is in contact with the inner edge of the sprocket member by the bump And a lubricating sleeve is disposed on the outer edge of the damping member, and the bottom of the lubrication© sleeve is sandwiched between the connecting portion and the damping member, and the side portion is disposed on the side of the damping member, and the fixing member is externally threaded. Locked into the internal thread section of the toothed disc member, a mandrel is threaded through the bearing, and passes through the toothed disc member, the damping member, the helical ring and the connecting portion Centrally, the mandrel is threadedly connected to the connecting rod located in the flower hub, and the bearing is disposed on the inner side of the connecting section and the simple part of the solid part, and the connecting rod and the ice system are connected. The lock is fixed on the frame and is pure and the money is moved, and the ratchet of the ratchet seat is elastic and the scale is closed. When the toothed plate has no power output, 200944396 When the electric bicycle and the bicycle move backward, the wheel drives a flower hub, and the flower ratchet seat is mounted on the ratchet seat. The ratchet is fixed to the ratchet shaft hole by a ratchet pivot point, and the ratchet column is attached to the ratchet shaft. The damper member slides toward the inner end of the damper, and the elastic piece of the damper member is resisted by the sprocket member, even if the ratchet is closed in the ratchet seat. Compared with the effects of the prior art: (1) When the pedal is stepped forward, the toothed disc member rotates and drives the helical ring gear and the damping member to rotate synchronously, and the resistance of the damping member causes the ratchet to open outward. When the ratchet teeth oppose the oblique tooth surface of the skew ring, the toothed disc member can drive the flower hub to rotate forward synchronously, and when the force of the toothed disc member is less than the resistance of the ratchet teeth, the damping member is formed with the ratchet seat. Synchronous rotation does not produce ratchet and helical tooth surface noise when the vehicle is retracted or when the pedal is reversed. (2) The protruding column of the ratchet is turned to the inner end of the slanting hole, and the protruding column is such that the ratchet is closed, that is, the ratchet is separated from the oblique tooth surface of the helical ring, so that the ratchet disk rotates by itself, and The positioning of the ratchet-restricted position piece, the ratchet is kept in a normally closed state, so that the front and rear rotation of the flower hub does not drive the ratchet disk, and when applied to the bicycle, the pedal pedal does not rotate. When the accidental injury occurs to the user, when applied to the electric bicycle, the drive motor will be untouched by the flower, so that the process of pulling the electric bicycle is more labor-saving.

A lubricating member (1311) is disposed on the ring (131), and the helical ring (43) is disposed on the outer edge of the ratchet (15) and the limiting member (14), and a damping member (3〇) sleeve The connecting piece (134) is connected to the protruding post (153) of the ratchet wheel (15) with the abutting hole (31), and the elastic piece (33) at the damping hole (32) is convex (331) Corresponding to the inner edge of the toothed disc member (40), and a lubricating sleeve (20) is disposed on the outer edge of the damping member (3), and the bottom portion (21) of the lubricating sleeve (20) is clamped to the connecting portion (134) Between the damper member (30) and the side portion (22) is disposed on the side of the damper member (3 〇), and a fixing member 45 (45) is threaded into the sprocket wheel In the inner threaded section (42) of (40), a mandrel (50) is threaded with a bearing (52) and passes through the sprocket member (40), the damper member (3 〇), the helical ring (43) and In the center of the connecting section (134), the mandrel (50) is threadedly connected to the connecting rod (〇) in the hub (1), and the bearing (52) is attached to the connecting section (134) and fixed The inner side of the piece (45). The actual movement situation, the performance is shown in Figure 3, 4, 5. Figure, a flower hub ratchet structure (2) is installed at the rear wheel of an electric bicycle or bicycle, The hub (10) is connected to the wheel by the wheel (11) and the connecting rod (12) and the mandrel (50) are fixedly fastened to the frame 200944396. The toothed disc member (4G) is toothed. The disk is driven by the chain, and the ratchet seat (the ratchet (15) on the (3) is held in a closed shape, and the chain drive (40) is rotated forward by the chain. 3)) The damping hole (10) is provided with an elastic piece (33)' and the convex piece (331) of the elastic piece (33) is in contact with the inner edge of the toothed plate member (10), so that the toothed plate member (40) drives the damping Rotating (3〇), the damper (10) of the damper (10) is connected to the ratchet ((5) The column (153) is slidably connected, and the damper member (10) is rotated forward to push the protrusion (153) to move outward, that is, the ratchet (10) is deployed outward, and the unfolded ratchet (10) is slammed on the skew ring ( 43) The oblique tooth surface (44) can drive the flower (1〇) and the wheel to rotate forward synchronously, wherein the damping member (30) and the toothed member (4〇) are frictioned to some extent. The resistance, when the damper member (30) pushes the ratchet wheel (13), is blocked by the stud (10) and rotates synchronously with the ratchet seat (13), whereas when the sprocket member (10) is reversed, the ratchet teeth (10) is closed, so that the helical ring (43) cannot drive the ratchet seat (13), that is, the noise of the ratchet (15) and the inclined tooth surface (44) is not generated. Please see from the 3rd, 6th, and 7th diagrams. When the gear unit (4〇) has no power output, when the electric bicycle and the bicycle move backward, the wheel drives a flower hub (1〇). And the flower hub (10) interlocks the ratchet seat (13), and the ratchet (15) is fixed on the ratchet seat (13) with a ratchet fulcrum (152) fixed to the ratchet shaft hole (135) 'the ratchet ( 15) The protruding post (153) is slid to the inner end of the damper (31) of the damper member (30), and the elastic piece (33) of the damper member (32) is received by the sprocket member (40) When the ratchet (15) is closed in the ratchet seat (13), the hub (10) is idling by itself, and the thrust of the boss (153) is greater than the resistance of the toothed member (4〇). When the damper member (30) rotates synchronously with the flower hub (10), the ratchet (15) is kept attached to the ratchet due to the ratchet (15) limited position member (14) 11 200944396. The state of the seat (13), by which the flower hub (10) cannot drive the toothed disc member (4〇) when the electric bicycle or the bicycle is pushed, so that the flower hub (10) does not turn before or after the bicycle hub (10) Drive the toothed disc member (4〇), when applied to a bicycle, its pedal Will turn Peru hurt Lai who, while new job at the electric bike, will not drive motor wire (1G) of the shaft, serve to make the transfer process more electric bike province's power. m In summary, the present invention has indeed reached a complicated structural design, and has improved invention content, (4) can be industrially viewable and progressive, and the present invention is not found in any publication 'also has new brewing When it comes to the stipulation of the subjective _ silk, Newfa filed a patent application review committee to grant legal patent rights, to pray.
