Abstract
The invention relates to an improved structure of a bicycle back wheel bearing support, and belongs to the technical field of bicycles. The improved structure of the bicycle back wheel bearing support comprises a hub component and bearing components, and is characterized in that: two groups of bearing components are arranged at two ends of the hub component; the hub component comprises a hub and an axle tube; each bearing component comprises a bearing, a sleeve, a shell and an outer threaded sleeve; the axle tube is sleeved in a central through hole of the hub, and extends out of two ends of the hub; a bearing inner ring is fixed on the extension parts of the axle tube, which extends out of the two ends of the hub; a bearing outer ring is fixed with the sleeve; the outer threaded sleeve is sleeved with the end of the axle tube; and the shell consists of two structures which are sleeved on the sleeve and mutually fixed through bolts. The invention has the advantage that: the improved structure is difficult to damage and more convenient to replace.
Description
Technical field
The present invention relates to bicycle rear bearing support structure-improved, belong to technical field of bicycles.
Background technology
The flower-drum assembling morphology of bicycle rack mostly is in flower-drum in-to-in end positions, to assemble bearing, places a central siphon afterwards again, and makes central siphon outermost two ends do combination with vehicle frame again; Yet be contained in the mode of the inner end positions of flower-drum with such bearing set; At first just, make bearing receive the restriction of flower-drum size; Again because bearing under long-term running, causes the ball in the bearing to produce distortion, even break and damage situation; Can only solve to change impaired bearing B mode, just can do replacing with making or have much ado so again but disassemble vehicle frame.
Summary of the invention
The objective of the invention is for solving the problems of the technologies described above, provide a kind of not fragile and change the bicycle rear bearing support improvement of bearing easily.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme:
Bicycle rear bearing support structure-improved, it comprises flower-drum assembly and bearing assembly, it is characterized in that: said bearing assembly has two groups, is arranged on the two ends of said flower-drum assembly; The flower-drum assembly comprises flower-drum and central siphon, and bearing assembly comprises bearing, sleeve, housing and external thread sleeve; Central siphon is sheathed on the central hole inside of flower-drum, and extends the flower-drum two ends, and bearing inner ring is fixed on central siphon and extends on the extension at flower-drum two ends, and outside race and sleeve are fixed, external thread sleeve fit and central siphon limit end; Housing is made up of two-part structure, and these two parts are linked on the sleeve and with bolt and interfix.
In the technique scheme of the present invention the central siphon of bearing through lengthening is installed in the two ends of flower-drum, is different from being installed in the flower-drum of prior art.This change makes the size of bearing no longer be limited by the size of flower-drum, it has been generally acknowledged that identical bearing, and the bigger power that it can bear of size is also big more; Therefore through the change of this structure, can effectively improve in the prior art the perishable problem of bearing in the flower-drum; Moreover, because bearing is arranged on outside the flower-drum, it changes also very convenient.Therefore use bicycle of the present invention repacking also preferably, more be received by the market.
Because the constructional feature of bicycle rack, front-wheel is stressed little usually, and trailing wheel is stressed big, so the present invention aims at the design of bicycle rear place.
Preferred as technique scheme, said bearing is a deep groove ball bearing.
In sum, the present invention has following beneficial effect:
1, the present invention has non-damageable advantage;
2, the present invention has the advantage of more convenient replacing.
Description of drawings
Fig. 1 is a structure exploded view of the present invention;
Among the figure, 1-flower-drum, 2-central siphon, 3-bearing, 4-sleeve, 5-housing, 6-external thread sleeve, 7-back vent, 11-central hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
This specific embodiment only is to explanation of the present invention; It is not a limitation of the present invention; Those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification sheets, but as long as in claim scope of the present invention, all receive the protection of patent law.
As shown in Figure 1, bicycle rear bearing support structure-improved, it comprises flower-drum assembly and bearing assembly, said bearing assembly has two groups, is arranged on the two ends of said flower-drum assembly; The flower-drum assembly comprises flower-drum (1) and central siphon (2), and bearing assembly comprises bearing (3), sleeve (4), housing (5) and external thread sleeve (6); Central siphon (2) is sheathed on central hole (11) inside of flower-drum (1); And extend flower-drum (1) two ends; Bearing (3) inner ring is fixed on central siphon (2) and extends on the extension at flower-drum (1) two ends; Bearing (3) outer ring and sleeve (4) are fixing, external thread sleeve (6) fit and central siphon (2) limit end; Housing (5) is made up of two-part structure, and these two parts are linked in sleeve (4) and upward and with bolt interfix.Back vent (7) then is fixed on the housing (5) of flower-drum (1) both sides.
Claims (2)
