Abstract
The invention discloses a structure of a small bicycle free wheel. The structure is provided with a forged gear ring and a forged ratchet hub which are independent from each other, and the gear ring and the ratchet hub are fixed together by rivets. The technique of the structure is simple, the fabrication cost is low, and meanwhile, quality is guaranteed.
Description
Technical field
The present invention relates to a kind of structure technology of bicycle part, specifically is a kind of structure of bicycle small flywheel.
Background technique
At present, the small flywheel of bicycle structurally is made up of two parts, that is: be made up of gear ring and ratchet hub; And both structurally are whole structural type, and the structural type of this integral body makes the geometrical construction of other part comparatively complicated, because the geometrical construction of other part is comparatively complicated; Thereby cause the manufacturing process of other part also correspondingly complicated, thereby improved part manufacture cost in addition, simultaneously; Because the geometrical construction of other part is comparatively complicated, the quality of part in manufacture process is difficult for guaranteeing in addition.
Summary of the invention
The objective of the invention is to: comparatively complicated to the existing geometrical shape of existing bicycle small flywheel manufacturing process comparatively complicated and that cause therefrom; The manufacture cost of part is higher in addition; Quality is difficult for the defective of assurance; The present invention provides a kind of structure of novel a kind of bicycle small flywheel, overcomes the existing existing above-mentioned defective of bicycle small flywheel.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: the structure of this a kind of bicycle small flywheel comprises gear ring, ratchet hub, rivet, and this invention is forged has separate gear ring and ratchet hub, and through rivet, gear ring and ratchet hub connection are fixed as one.
Beneficial effect: the present invention is simple structurally, reduces the manufacture cost of product, simultaneously, ensures the quality of products.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention.
Shown in the figure: 1. gear ring, 2. ratchet hub, 3. rivet.
The practical implementation method
In the drawings, the structure of this a kind of bicycle small flywheel comprises gear ring 1, ratchet hub 2, rivet 3, and this invention is forged has separate gear ring 1 and ratchet hub 2, and through rivet 3, gear ring 1 and ratchet hub 2 connections are fixed as one.
