Description
Technical field
The utility model relates to a kind of fluted disc holder structure of bicycle hub, especially refers to a kind ofly be coated with the fluted disc seat of ceramic surface with electroplating processes, to improve the hardness and wear resistance of fluted disc seat.
Background technology
Press, its fluted disc seat is meant a kind of attachments of a bicycle, this fluted disc seat must be able to link fluted disc and flower hub, and has a function of unidirectional drive, and known a kind of bicycle crank holder structure, as shown in Figure 6 and Figure 7, this fluted disc seat 30 has a tooth portion 31 and a ratchet part 32, the surface of this tooth portion 31 convexes with a plurality of tooth bars 311, this tooth portion 31 is used to be arranged with at least one fluted disc 40 again, and this fluted disc 40 is formed with a meshing hole 41, utilize meshing hole 41 to intermesh with tooth bar 311, make fluted disc 40 form the interlock state with fluted disc seat 30, these ratchet part 32 places are provided with a plurality of ratchets 321 and a plurality of shell fragments 322, by ratchet 321 these bicycle hubs of unidirectional interlock, wherein, bicycle is in order to reduce the overall weight of car body, can adopt the aluminium material or the composite materials of lighter weight in a large number, therefore fluted disc seat 30 is common is to be made by aluminium material, but ratchet 321 and fluted disc 40 that aluminium material is made compared to iron material or steel will be wearing and tearing easily or distortion, therefore, the fluted disc seat 30 that has the dealer that aluminium material is made carries out the dura mater anodizing, desire to improve thus the hardness of fluted disc seat 30, yet, other sees also shown in Figure 7, fluted disc seat 30 after its dura mater anodizing still belongs to the model of aluminium material to be raised, and can't form enough hardness, do not have resistance to abrasion especially, and this ratchet 321 is owing to must bear the antagonistic force of bicycle hub end, therefore must use hardness higher steel or iron material to make, compared to the ratchet part 32 that the articulates ratchet 321 hardness deficiency that just seems, and in the process of start, this ratchet part 32 can be subjected to compressing and friction in ratchet 321 places that are articulated, thereby generation has ratchet gap 323 between ratchet 321 and ratchet part 32, again this ratchet gap 323 make ratchet 321 can't held stationary in ratchet part 32, cause bicycle in the process of trampling, to have moment to step on empty sensation, especially can the additive incrementation ratchet 321 with the impact wreckage of ratchet part 32, the durability of bicycle is reduced, this is the problem of fluted disc seat 30 hardness deficiencies, the fluted disc 40 that other these steel are made is with unidirectional compressing tooth bar 311, also can make these tooth bar 311 places produce deformed damaged, allow fluted disc 40 embed especially to tooth bar 311 ends of fluted disc seat 30, causing fluted disc 40 to block in fluted disc seat 30 can't separate, and being all fluted disc seat 30 hardness in sum not enough is known defective.
Another kind of again known fluted disc holder structure, see also shown in Figure 8, its fluted disc seat 50 has the tooth portion 51 of an end and the ratchet part 52 of the other end, this tooth portion 51 is used to connect this bicycle crank, and ratchet part 52 is used to connect bicycle hub, this fluted disc seat 50 is for improving the hardness of tooth portion 51, be to be equiped with a plurality of catch 53 in tooth portion 51 places, this catch 53 is made for steel or iron material, though utilize catch 53 can improve the hardness of fluted disc seat 50, but the above-mentioned known configurations of detailed sight is not difficult to realize that it has remained a little weak point, major cause is a plurality of catch 53 of fluted disc seat 50 installings, and catch 53 has increased many weight compared to aluminium material, makes bicycle can't keep lightweight, this catch 53 is also come off by tooth portion 51 places easily again, also can collide the tooth portion 51 of fluted disc seat 50 equally and cause distortion and wearing and tearing, comprehensive above-mentioned disappearance if can be under the situation that does not increase fluted disc seat weight, improving the hardness and wear resistance of fluted disc seat, is the technical matters point that solves for the utility model desire.
In view of this, the applicant this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.
