Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Fig. 5 to Fig. 8, the present invention easily vertical outer pawl formula ratchet wheel hub preferred embodiment of group comprises a mandrel unit 30, a housing 40, an actuator 50, a ratchet group 60 and an elastic component group 70.
This mandrel unit 30 comprises an axostylus axostyle 31 extended along an axis L, and is mounted on several bearings 32 of this axostylus axostyle 31.
This housing 40 comprises one around this axis L and defines the perisporium 42 of an endoporus 41, and be formed at an inner ring surface 421 of this perisporium 42 and be positioned at several openings 43 and several containing grooves 44 of these endoporus 41 1 ends, each containing groove 44 is communicated with these endoporus 41 by an opening 43.
Each containing groove 44 has respectively a groove bottom away from this opening 43 441, and be connected this groove bottom 441 with this opening 43 and be a pin-joint part 442 that lacks the circle shape, as for the symmetrical position in this pin-joint part 442, another pin-joint part 443 can be set, this another pin-joint part 443 also can be set.
The bearing 32 that this actuator 50 is installed on this mandrel unit 30 can rotate around this axis L, comprise the endoporus 41 that stretches into this housing 40 and in the face of the ratchet ring 51 of described containing groove 44, and one-body molded and be positioned at the outer sprocket wheel 52 of this housing 40 with this ratchet ring 51.
This ratchet ring 51 has several ratchets 511, and each ratchet 511 has respectively a drive surface 512, and this drive surface 512 is towards this pin-joint part 442.
This ratchet group 60 comprises several ratchets 61 of the pin-joint part 442 that is applicable to be arranged on described containing groove 44, the pivot part 611 that each ratchet 61 has respectively a circle shape and is rotating with this pin-joint part 442, one extends through the claw 612 of this opening 43 in order to the engagement of the drive surface 512 with this ratchet ring 51 from this pivot part 611, and a slot 613 that is arranged at this claw 612.
Further, each ratchet 61 also has respectively and is positioned at rightabout one first side 614 and one second side 615, reach the outer surface 616 of this first side 614 of a connection and this second side 615, this slot 613 is formed on this outer surface 616 and is communicated with this first side 614 and this second side 615, design whereby, by the one-body molded whole piece shape that is made into of several ratchets 61, once cut described slot 613, along this first side 614, this second side 615 dissects, and can make the moulding of each ratchet 61 identical.
This elastic component group 70 comprises the several elastic components 71 that are arranged between described containing groove 44 and described ratchet 61, with so that the claw 612 of described ratchet 61 keeps engagement with this ratchet ring 51, in this preferred embodiment, the spring plate of described elastic component 71 for forming with the steel disc bending, each elastic component 71 has respectively one and is installed on the slot 613 of each ratchet 61 and friction tight inserted sheet 711 each other, one extends the butted butted piece in this groove bottom 441 712 from this inserted sheet 711, and a deflection sheet 713 between this inserted sheet 711 and this butted piece 712.
Preferably, this inserted sheet 711 inserts this slot 613, and this deflection sheet 713 is between this outer surface 616 and this groove bottom 441.
As shown in Fig. 8, Fig. 9, Figure 10, the moulding of this elastic component 71 can have different variations.
Before the vertical flower of group hub, first the inserted sheet of each elastic component 71 711 is inserted to the slot 613 of each ratchet 61, namely assemble in advance each elastic component 71 and each ratchet 61.
During the vertical flower of group hub, in each containing groove 44 that just can synchronously pack into corresponding with each ratchet 61 by each elastic component 71, make described pivot part 611 lay respectively in described pin-joint part 442 simultaneously, and make butted 712 of the described elastic component 71 butted groove bottom in described containing groove 44 441 respectively, make the claw 612 of described ratchet 61 keep engagement with the drive surface 512 of the ratchet 511 of this ratchet ring 51, so, when this sprocket wheel 52 is subject to clockwise direction driving force (seeing the arrow 80 of Fig. 8), the drive surface 512 that just can pass through the ratchet 511 of this ratchet ring 51 drives described ratchet 61, and generation drives the effect that these housing 40 clockwise directions rotate, on the contrary, when this sprocket wheel 52 is subject to the counter clockwise direction driving force, described ratchet 61 can be removed engagement from described ratchet 511 escapes, can only produce idle running.
Conclude above-mentionedly, the present invention easily vertical outer pawl formula ratchet wheel hub of group has effect as described below and advantage:
One, the present invention is by slot 613 and friction tight design each other that the inserted sheet of each elastic component 71 711 is inserted to each ratchet 61, can assemble in advance described elastic component 71 and described ratchet 61, no matter described elastic component 71 and described ratchet 61 will be packed whereby into to described containing groove 44, perhaps described elastic component 71 and described ratchet 61 to be taken out to described containing groove 44, all only need a step just can complete, can improve assembling convenience of the present invention, save and assemble man-hour, enhance productivity.
Two,, on practice, described elastic component 71 is manufactured, is organized and stand in advance by upstream parts plants with described ratchet 61, for the flower hub producer, directly obtains the pre-group of assembly parts stood, and except the assembling simplification, in the operation of product examine, part management, can save half.
Three, the matching design of this ratchet 61 of the present invention and this elastic component 71, pallet piece 23 compared to TaiWan, China M273524 Patent Case, there is the effect that global design is succinct, assembling is easier, in addition, it is rotating shaft that this ratchet 61 of the present invention be take this pivot part 611, take pivot 271 as rotating shaft with the pawl body 27 of TaiWan, China M273524 Patent Case, both design difference, and the present invention is filled up and friction tight design each other by the inserted sheet 711 of each elastic component 71 by the slot 613 of each ratchet 61, can not destroy the structural strength of each ratchet 61.
