Description
Technical field
The utility model is related to a kind of colored hub structure, particularly a kind of colored hub driving structure.
Background technology
A kind of colored hub driving structure of the prior art, please refer to shown in Fig. 7, it is included:One flower hub body 40, its
Wholeheartedly axle 41 axially are equipped with, the one end of flower hub body 40 connects space 42 provided with one group, are connect in the group and ring-type is provided with space 42
A Coupling 43, the inner circumferential continuous arrangement of Coupling 43 is equipped with axially arranged multiple teeth 431;One sleeve 50, in hollow
Tubular, and provided with an ostiolate open end 51, the inner circumferential continuous arrangement of open end 51 is equipped with axially arranged multiple teeth
511, and be connected with the open end 51 and connect space 42 in the group, and the heart axle 41 is worn sleeve 50;One drive component 60, comprising
There are two ratchet rings 62 of elastic component 61 and first, the second ratchet rings 63, two elastic components 61 are all a kind of scroll spring, and
Two elastic components 61 are sheathed on into the group of colored hub body 40 respectively to connect inside the open end 51 of space 42 and sleeve 50, this
One ratchet ring 62 and the periphery continuous arrangement of the second ratchet ring 63 are equipped with chimeric teeth portion 621,631, the one end of the first ratchet ring 62
The radially continuous engaging teeth portion 622 provided with default gradient of junction, and corresponding engaging tooth of a terminal area of second ratchet ring 63
Portion 622 and it is relative be provided with meshing teeth 632, the group that first ratchet ring 62 is mounted on colored hub body 40 is connect in space 42, and with
The chimeric teeth portion 621 of periphery engages limitation with multiple teeth 431 of the Coupling 43, and second ratchet ring 63 is then mounted on sleeve
Inside 50 open end 51, while limitation is engaged with multiple teeth 511 with the chimeric teeth portion 631 of periphery, also by first ratchet ring
62 and second ratchet ring 63 press against in corresponding elastic component 61, make first ratchet ring 62, the second ratchet ring 63
Pushed out by elastic component 61 to and by engage teeth portion 622 and the intermeshing formation gearing of meshing teeth 632, to complete one
Plant flower hub driving structure.
By said structure, when flywheel drives the sleeve 50 to rotate towards a direction, please refer to shown in Fig. 8, the set
The meshing teeth 632 of 50 brake second ratchet rings 63 of cylinder is engaged with the engaging teeth portion 622 of the first ratchet ring 62, and can interlock this
Flower hub body 40 is rotated;When flywheel drives the sleeve 50 towards when rotating backward, then please refer to shown in Fig. 9, first ratchet
