The specific embodiment
As shown in Figure 1 and Figure 2, the wheel hub 20 that a side is provided with annular tip edge 22 is used and be mounted on to the utility model.
The utility model comprises inner core 10, transmission fluted disc 12, several unidirectional ratchet 40 and resilient rings 50.
Transmission fluted disc 12 is mounted on inner core 10 outer ends, and transmission fluted disc 12 is for being combined in the structure kenel of inner core 10; It also is the structure kenel that is formed as one in inner core 10.
As Fig. 4, shown in Figure 5, two groups of grooves 61,62 that inner core 10 inner peripheral intervals rings are established and are misplaced, kenel is opposite are even also the direction that puts in order of the hub switch side limiting section 63 of first group of groove 61 and second group of groove 62 and increment limiting section 64 is opposite.Whereby, as Fig. 5, shown in Figure 6, the difference of utilizing unidirectional ratchet 40 to be mounted on first group of groove 61 or second group of groove 62 can change the moving direction of its card, make the applicable left and right side that is assembled in wheel hub 20 of unidirectional ratchet 40 to.
Must supplemental instruction be, in aforementioned two kinds of example structure, if the profile of tooth monocline of the annular tip edge 22 that wheel hub 20 inwalls are set is when kenel, then when inner core 10 commutation assemblings, annular tip edge 22 also commutation group is thereupon established and can be obtained the moving effect of card, if but the profile of tooth of annular tip edge 22 to be diclinic then not subject to the limits when kenel.
As Fig. 7, shown in Figure 8, the utility model also can be applicable to wheel hub with on the flywheel 70, flywheel 70 centers are provided with and can be screwed together in the screw seat 72 that is arranged at wheel hub 20B one end external thread section 23, the neighboring of flywheel 70 can constitute screw seat 72 and transmission fluted disc 71 contrarotation mutually by the ball bearing of main shaft transmission fluted disc 71 that is pivoted.Transmission fluted disc 71 inwalls are provided with annular tip edge 76.
Screw seat 72 neighboring spacer rings are provided with respectively for 74 groups of several grooves 73 of establishing of several unidirectional ratchets, and are provided with the hub switch side 741 that supplies unidirectional ratchet 74 respectively and increment 742 ccontaining hub switch side limiting section 731 and increment limiting section 732 in each groove 73 bottom.
The pivot end 741 of several unidirectional ratchets 74 and increment 742 are placed in the hub switch side limiting section 731 and the increment limiting section 732 of each groove 73 bottom of screw seat 72, and enclose spacing by resilient ring 75 covers.
The hub switch side limiting section 731 of screw seat 72 grooves 73 and increment limiting section 732 bottom surfaces are provided with the space kenel of two symmetrical concave arc surfaces, that is hub switch side limiting section 731 and increment limiting section 732 bottom surfaces are all corresponding with 741 pairs of the hub switch sides of unidirectional ratchet 74 and coincide, with constitute unidirectional ratchet 74 no matter its increment 742 for suitable, contrary in the groove 73 that all can be mounted on screw seat 72; Whereby, make the applicable left and right side that is assembled in wheel hub 20B of unidirectional ratchet 74 to flywheel.
As shown in Figure 9, two groups of grooves 81,82 that screw seat 72 spacer rings are established and are misplaced, kenel is opposite are even also the direction that puts in order of the hub switch side limiting section 83 of first group of groove 81 and second group of groove 82 and increment limiting section 84 is opposite.Whereby, the difference of utilizing unidirectional ratchet 74 to be mounted on first group of groove 81 or second group of groove 82 can change the moving direction of its card, make the applicable left and right side that is assembled in wheel hub 20 of unidirectional ratchet 74 to.
Must supplemental instruction be, in aforementioned two kinds of example structure, if the profile of tooth monocline of the annular tip edge 22 that wheel hub 20 inwalls are set is when kenel, then when inner core 10 commutation assemblings, annular tip edge 22 also commutation group is thereupon established and can be obtained the moving effect of card, if but the profile of tooth of annular tip edge 22 to be diclinic then not subject to the limits when kenel.
Wherein, as Fig. 7, Fig. 8, embodiment illustrated in fig. 9 in, the state after its unidirectional ratchet 74 commutation assemblings with as Fig. 2, Fig. 3 and Fig. 5, difference same principle shown in Figure 6.
The utlity model has following effect:
The utility model is compared with prior art has following effect:
1, the utility model applicable be assembled in the wheel hub left and right side to, use to adapt to different car moneys, thereby reduce manufacturing cost and increase economic efficiency.
2, the particular design that is provided with two symmetrical concave arc surface space kenels by the hub switch side limiting section and the increment limiting section bottom surface of inner core upper groove, no matter its increment is suitable, contrary towards all being mounted in the inner core groove to constitute unidirectional ratchet, make the applicable left and right side that is assembled in wheel hub of unidirectional ratchet to, reach the economic benefit and the preferable industry applications that reduce manufacturing cost.
3, another special construction kenel design of two groups of grooves that the interval is misplaced, kenel is opposite is set by inner core, difference of utilizing unidirectional ratchet to be mounted on first, second group groove can change the moving direction of its card, make the applicable left and right side that is assembled in wheel hub of unidirectional ratchet to and reach economic benefit and the preferable industry applications that reduces manufacturing cost equally.
4, technical characterstic of the present utility model also can be applicable to wheel hub with on the flywheel structure and obtain equal effect.
