The specific embodiment

Referring to shown in Fig. 1 to Fig. 5, is with better example explanation, not the utility model is done to any pro forma restriction.At first refer to Fig. 1, the utility model flower hub spoke fixed sturcture includes flower hub 1 and a plural spoke 2.This flower hub 1 is equipped with an axis hole axially run through 11, and the two ends of flower hub 1 form respectively a floral disc section 12.Floral disc section 12 surfaces are equipped with plural spaced through hole 13, relative this axis hole 11 of this through hole 13 is and is horizontally disposed with, further in each through hole 13 hole walls, be provided with a profile groove of opening laterally 14 (profile groove 14 from respectively this through hole 13 extend to these floral disc section 12 peripheries), and being provided with a positioning groove end 15 in profile groove 14 ends, this positioning groove end 15 is angle with through hole 13 form is set.Respectively the two ends of this spoke 2 are respectively arranged with a head end 21 and a free end 22, respectively this spoke 2 is by with this free end 22 respectively, being arranged in respectively respectively this through hole 13, and respectively this spoke 2 moves to respectively this positioning groove end 15 and is resisted against respectively this positioning groove end 15 with this head end 21 respectively through this profile groove 14 respectively respectively, and be connected in wheel rim 3 with this free end 22 respectively.

Further describe again the architectural feature of flower hub 1, refer to shown in Fig. 1 and Fig. 2, each floral disc section 12 includes the linkage section 121 that an end is connected in colored hub 1 and extends towards radial outside, and the extension 122 that is connected in these linkage section 121 other ends, and extension 122 is the setting of curved arc shape towards flower hub 1 direction, make the c-shaped structure of extension 122 section, this through hole 13 is arranged at linkage section 121,14 of this profile grooves are formed at linkage section 121 and extension 122, and this positioning groove end 15 is positioned at extension 122.The section width of this extension 122 by these linkage section 121 directions to these extension 122 bearing of trend convergents.

Next illustrate that spoke 2 is connected to the occupation mode of colored hub 1, refer to shown in Fig. 3, spoke 2 is arranged in through hole 13 with free end 22 by the floral disc section 12 inner sides wherein space of 12 (i.e. two floral disc sections), as shown in Figure 4, and mobile spoke 2 is moved to positioning groove end 15 through profile groove 14, as shown in Figure 5, allow the head end 21 of spoke 2 be resisted against the below outer rim of positioning groove end 15, now please refer to Fig. 6, the free end 22 of spoke 2 is locked on wheel rim 3 by a locking 31 again.So be able to be locked on wheel rim 3 by locking 31, make spoke 2 present extended state, and closely support positioning groove end 15 by

head end

21,2 of all the other spokes are assembled according to aforesaid way, separately with bearing 101, be connected to two nose ends of colored hub 1 its axis hole 11, and mandrel 102 wears axis hole 11 and this bearing 101, finally, at 102 liang of terminal position locking side covers 103 of mandrel location bearing 101, according to above-mentioned assembling mode, formed complete wheels.

It is worth mentioning that, the utility model is that to take the colored hub 1 of front-wheel be example in above-described embodiment, also can adopt the colored hub 4 in the trailing wheel form, as shown in Figure 7, at this, only for difference, be illustrated, something in common no longer repeats to repeat, the difference part is that flower hub 4 includes an assembly in the pawl seat 42 in floral disc section 41 outsides wherein, and dispose to be meshed with pawl seat 42 in axis hole 11 nose ends in corresponding this floral disc section 41 and be unidirectional or two-way drive transmission group (not drawing transmission group in accompanying drawing), because pawl seat 42 and the induced way of transmission group are not focused on technology for the utility model, therefore, in this description will be omitted.

The utility model flower hub spoke fixed sturcture is the applicable colored hub for the disc brake system form also, as shown in Fig. 8 in accompanying drawing and Fig. 9, this flower hub 5 has a bulge loop be connected 53 in the linkage section 52 of a floral disc section 51 wherein, and the relative axis hole 54 concentric settings of bulge loop 53, and be equipped with a group connecting part 55 along bulge loop 53 radial surfaces, and it is formed with plural joining hole 56 and is arranged in this group connecting part 55, so disc 57 is able to be locked in joining hole 56 by screw 58, and disc 57 is installed on group connecting part 55 1 sides.In addition, flower hub 5 includes a pawl seat 59 that is connected to these flower hub 5 another floral disc section 51 outsides, and pawl seat 59 is positioned at the opposite sense that floral disc section 51 is provided with bulge loop 53.

Via understanding after above-mentioned explanation, the utility model flower hub spoke fixed sturcture, bearing 101 is installed in axis hole 11 nose ends and can be connected with structures such as through hole 13, profile grooves 14, in the time of can effectively avoiding in the past assembling spoke because the space between dependency structure easily causes aqueous vapor, dust to be invaded, so can there is good waterproofing effect, and the utility model flower hub 1 profile is able to by lathe turning, only need carry out with milling machine the processing that through hole 13, profile groove 14 and positioning groove end 15 can complete colored hub 1 again, so as to reaching the easy characteristics of colored hub 1 processing.And, when the dismounting of spoke 2 is carried out in maintaining, can save the step that known technology needs first removal side cover, only need directly in floral disc section 12, to be substituted spoke 2 and get final product, therefore the utlity model has easily assembled effect.

Be only in order to explain preferred embodiment of the present utility model from the above mentioned; not the utility model is done to any pro forma restriction; therefore; all have do relevant any modification of the present utility model or change under identical utility model spirit; for other form that can implement according to this and there is same effect, must be included in the category of the utility model intention protection.
