Referring to Fig. 8, the first round disc elements (not shown) docks the second wheel disc elements (not shown), the first interlocking structure Make 50 the second combined structures of insertion 110, and the first combined structure 60 of insertion of the second interlocking construction 100.Furthermore, first Two the first columns 52 of interlocking construction 50 are embedded between two the second arc components 112 and 114 of each second combined structure 110 And shape is positioned to be formed in two the second post holes 116, similarly, two the second columns 102 of the second interlocking construction 100 are embedded in Between two the first arc components 62 and 64 of the first combined structure 60 and in two the first post holes 66.

Fig. 1 and Fig. 9 are referred to, locked assembly 140 includes a screw 142 and a nut 144；Screw 142 has an outer spiral shell Line 146；Nut 144 includes a butting section 148, and the internal face of butting section 148 has an internal thread 149.

Again referring to Fig. 9, nut 144 is located in relative the first lockhole 38 and the second lockhole 88, the lock of screw 142 fits over spiral shell The axle of cap 144 is inside, and the first round disc elements 30 and second that so each locked assembly 140 is worn and interlocking is relative take turns disc elements 80。

In accordance with the above, second wheel of the docking of first round disc elements 30 disc elements 80, interlocking is provided by each locked assembly 140 Effect, each first interlocking construction 50 are respectively in connection with each second combined structure 110, each second interlocking construction 100 respectively in connection with each the One combined structure 60, each first chimeric part 40 are respectively in connection with respectively second embedded hole 96 and each second chimeric part 90 respectively in connection with each First embedded hole 46 so that first round disc elements 30 are securely joined with the second wheel disc elements 80, and make first round disc elements 30 And second wheel disc elements 80 coat fluted disc element 10 securely.

Referring to Fig. 10, first round disc elements 30 combine the second wheel disc elements 80, the first convex portion of first round disc elements 30 72 the second convex portions 122 for being connected the second wheel disc elements 80, the first recess 74 of first round disc elements 30 are connected the second wheel disc member Second recess 124 of part 80, with this engaging a belt 150.Being can be by the kind of drive from fluted disc element 10 with the present embodiment Belt 150 is engaged in the combination that the form of engagement chain is converted into combining the second wheel disc elements 80 with first round disc elements 30, makes it Reach good easy variation effect.

Figure 11 is referred to, under the configuration that first round disc elements 30 and second take turns the clamping fluted disc element 10 of disc elements 80, the The butting section 148 of the adjacent lock member 140 of each first breach 39 of each first lockhole 38 of one wheel disc elements 30；Likewise, the The butting section 148 of the adjacent lock member 140 of each second breach 89 of each second lockhole 88 of two wheel disc elements 80.Fluted disc element 10 Rotate, according to the rotation direction of fluted disc element 10, the promotion face 14 of each sprocket 12 can contact the butting section 148 of lock member 140, And then the combination of the first round disc elements 30 and second wheel disc elements 80 is promoted to rotate.Because lock member 140 can be by metal material Material is made, and the driving force that sprocket 12 is provided is acted on lock member 140, therefore not only transmits bigger torsion, can be with Reduce each sprocket 12 and squeeze the situation that first round disc elements 30 and second take turns disc elements 80, therefore the present embodiment has optimization overall The effect of structural strength.

Referring again to Figure 10, fluted disc element 10 configures a crank 152, then first round disc elements 30, second take turns disc elements 80, The combination of fluted disc element 10 and crank 152 is to as active driving mechanisms.

It will be appreciated that first round disc elements 30, second take turns the minification that disc elements 80 and fluted disc element 10 can be appropriate, The first round disc elements 30, second of so tool reduced size, which take turns disc elements 80 and the combination of fluted disc element 10, can be used as one voluntarily The trailing wheel follower of car, and belt 150 of arranging in pairs or groups is to bear the torsion that active driving mechanisms are transmitted.

Figure 12 is referred to, another embodiment of the utility model is still fluted disc element 10, wheel assemblies 20 and each locked assembly 140 combination.In order to meet that fluted disc element 10 can touch the technical characteristic of lock member 140, first round disc elements 30 Between first lockhole 38 and the first adjacent teeth groove 36, there is the first breach 39.The second lockhole 88 and phase of second wheel disc elements 80 Between the second adjacent teeth groove 86, there is the second breach 89.The difference of the present embodiment and previous embodiment is：Each lock member 140 In addition to screw 142 and nut 144, also comprising a becket 160.Wherein screw 142 and nut 144 is to the wheel disc of interlocking first Element 30 and second takes turns disc elements 80.

Refer to Figure 12 and Figure 13, becket 160 configures takes turns disc elements 80 and relative in first round disc elements 30 and second First lockhole 38 and the second lockhole 88, in other words, becket 160 is between two the first teeth groove 36, and two the second teeth groove Between 86, and the adjacent breach 89 of first breach 39 and second in outer surface of becket 160.It is to be rotated with fluted disc element 10, can makes The contacting metal ring 160 of sprocket 12, reached with this and transmit bigger torsion, and each sprocket 12 can be reduced and squeeze the first wheel disc member Part 30 and second takes turns the situation of disc elements 80.

Above-described embodiment is only illustrative technology of the present utility model and its effect, new not for this practicality is limited Type.It is any it is ripe can be in the case of without prejudice to technical principle of the present utility model and spirit, to above-mentioned in technique personage Embodiment is modified and changed, therefore rights protection scope of the present utility model answers claim institute as described later Row.
