Description of the Invention: [Technical Field] The present invention relates to a flower hub structure for bicycles, and more particularly to a "normally closed bicycle rear hub structure" in which a ratchet member is built into a through hole. Rolling parts, due to the difference in the rotation of the disc sleeve and the age piece, so that the shaft can be moved to match the control groove to produce the effect of the phase support, thereby making the Hessian crane more smooth and reducing the use. The wear and tear caused by the increase in durability. [Prior Art] The ratchet structure of the flower hub on the light vehicle, as shown in Figures 8 and 9, includes: - the sprocket holder (10) is provided with a plurality of control blocks (5) at the end faces, which Some control ghosts (51) s concave shaft has interlocking groove (10)' - ratchet member (10) includes a ratchet seat ((1), ratchet (10) and elastic member (10), the ratchet seat (10) is provided with a plurality of ratchets on the outer wall surface The groove (611) and the ratchet groove (10) are provided with ratchet teeth (10), and the protruding rods of the ratchet teeth (10) are slidably disposed in the interlocking groove (10), and the ratchet seat (5) is at the outer wall surface and the ratchet (10) The through hole (10) is recorded on the outer surface and the tightening ring groove (65) is annularly opened and the elastic member (8) is sleeved in the tightening ring groove (65), and the collision ring (7) is provided with the positioning groove. (8), and the positioning of the groove (5) and the ratchet seat (6)) _ (2) deed. And forming a synchronizing shape, the retaining ring (7〇) is provided with a damping member (73) at the perforation (10), and the inner edge of the damping member (10) is in close contact with the supporting sleeve (10), and the flower shell (10) is at the inner wall The card has a helical ring (8), and the helical ring (10) is annularly disposed at the outer end of the ratchet (4). When the rider knows to step on the __, the sewing seat (10) thief chain belt 201113167 moves 'and produces the rotation difference between the sprocket seat (50) and the ratchet member (60), at this time the sprocket seat (Μ) linkage The groove (52) is axially rotated, and the linkage post (621) of the push ratchet (62) is slid from the inner end to the outer end, thereby forming a linkage between the sprocket seat (5 〇) and the ratchet member (10). In the state, when the pedal is stepped on, the sprocket seat (5 〇) rotates in the reverse direction, and the linkage groove (52) of the spur base (50) at the control block (51) is also reversed.

Bit effect. The actual side of the situation 'requested from the 3rd, 4th, and 5th pictures & shown in Figure 2' is mainly placed at the rear wheel of the bicycle, the sprocket sleeve (10) is used to connect the sprocket ( The figure is not driven by the chain, and the spindle can be driven by the chain linked by the bicycle pedal end, and the mandrel (12) is fixed to the frame, and the hub (4〇) is used to connect the chain. The rear wheel of the bicycle, when the bicycle is not in use, the ratchet (22) is restrained by the elastic ring (26) and is limited to the receiving groove (21), and then is blocked by the damping member (3〇) on the ratchet The outer side of the piece (2〇) prevents the ratchet (22) from being moved to the left and right, and the rolling member (23) is housed in the control groove (13ι) of the ratchet seat (13) by the ratchet (22) The contracted state, such that the ratchet (22) and the bevel ring (42) of the hub (4〇) are not in contact with each other, and when the bicycle is stepped on the pedal, the toothed sleeve (10) Driven by the chain, the ratchet sleeve (10) rotates while the ratchet member (2〇) is interlocked with the damper member (30) by the bump (27) and is subjected to the damper member (30). The resistance is affected, but it is not easy Being rotated, thereby generating a rotational position difference between the toothed sleeve (10) and the ratchet member (2), wherein the control groove (131) of the ratchet seat (a) is axially rotated and pushes the ratchet (22) a rolling member (23) at the bottom end, at which time the rolling member (23) is detached from the control groove (131) in a rolling manner, thereby producing the effect of ejecting the ratchet (22), the ratchet (22) The shaft portion (221) is yawed at the outer end of the axial center of the accommodating chamber (21), so that the ratchet teeth (22) can be meshed with the helical ring gear (42), thereby forming the sprocket sleeve (10) and the ratchet teeth. The interlocking state of the piece (2〇), and at the same time, when the ratchet (22) is accommodated to the outer yaw of (21), the ratchet (22) will abut against the outer helical ring (42), and 201113167 Rotating the flower hub shell (40) by the helical ring (9), which is to drive the rear wheel of the bicycle to rotate, and when stepping on the pedal to reverse, please refer to the 6th, 7th _ The sprocket sleeve (10) rotates in a reverse direction, and the control sleeve (10) of the sprocket sleeve (10) at the ratchet seat (10) also rotates in the opposite direction, and the ratchet member (10) end is affected by the resistance of the damper member (10). At rest, the rolling element (10) is ratcheted (10) The rotation of the ratchet member (10) is trapped in the control groove (10). At this time, the ratchet (4) is not subjected to the top of the rolling member (10), and the ratchet (10) is pushed in the reverse direction with the helical ring (10). In the chamber (2)), the ratchet is spliced with the nucleus of the (10) end of the nucleus. This eliminates the sound of the ratchet (22) and the helical ring (10) due to continuous collisions and prevents excessive collision. Corresponding to the structural damage, if the rear wheel end drives the hub (4〇) to rotate, the ratchet (10) is pushed by the helical ring (10) and cooperates with the resistance generated by the end of the damping member (10). The ratchet (10) is stably closed in the accommodating chamber (10), so that the ratchet (10) and the helical ring (10) are kept normally open, so that the ratchet shell (40) does not drive the ratchet before and after the hub (40). (10), the ratchet member (20) can be achieved by the limit block (24) and the limit post (222 clearing toothed sleeve ((8) protruding K14) to achieve the effect of the woven turn, so that the shaft (2)) can only roll at the appropriate position of the control slot (10), thereby increasing the flexibility of its interlocking state. In summary, the foot pedal can not be rotated when the bicycle is pulled. Effect, and to achieve its silent effect, to serve the gambling high practical person. The structure of the above specific embodiment can provide the following benefits: (1) the ratchet member (20) has a rolling member (2) built in the through hole (10), and the rotation position generated by the sleeve (10) and the ratchet member (10) Poor, so that the rolling element (10) can be controlled in a rolling manner. * --· 2 201113167 7 (131) produces the effect of the outward top support, borrowing the age of (10) reading the lion is more smooth and less use of the Wear and tear to increase its suitability; (2) its components (30) 4*, and inside the perforation (10) are equipped with a plurality of steel balls ((4) and elastic members (35)' and by elastic members (35) The tension pushes the steel ball (9)) so that the steel ball (10) is directly forced by the sleeve (32) to thereby generate the rotational resistance of the damping member (10), and the tension of the elastic member (35) is finely locked (10) The stability of the damper (10) is added to the woman.
