Description
Technical field
The utility model relates to a kind of wheel assembly, is specifically related to the hollow wheel assembly of a kind of split combination type.
Background technology
Collapsible, the advantage such as easily control, be easy to carry that folded bicycle has, need to be by external instrument, by manually from being about to, car folds or expansion, after folding in folding use procedure yet, can more conveniently deposit and move, avoid the outdoor hidden danger of depositing.
Current most folded bicycle outward appearance is similar or converted by bicycle with bicycle, pedal two ends are provided with wheel, vehicle frame folding is horizontal doubling, folding process is complicated, order before and after folding rear front-wheel and trailing wheel keep, and the longitudinal exposed part of lateral direction of car is too lengthy and tedious, volume is still larger, do not save and take up room, and to contact dust more with ground at ordinary times due to wheel, is not easy to carry or move at a distance.Current
The folded bicycle that particularly trailing wheel is single wheel, under folded state, trailing wheel because and front-wheel arranged side by side, the utilized space that cannot insert front-wheel, folding volume is large, takes up room many, carries also inconvenient.
How to research and develop that a kind of degree of shrinkage is high, volume after folding is little, without the Split type hollow wheel of spoke and wheel shaft, become the technical barrier that those skilled in the art need solution badly.
Summary of the invention:
Technical matters: design the hollow wheel assembly of a kind of split combination type, merge into one and rotate flexibly without spoke, without hollow whole wheel of wheel shaft during use, own wt is light, and when folding, wheel divides body deformability, and degree of shrinkage is high, and folding volume is little.
Technical scheme: design the hollow wheel assembly of a kind of split combination type, it is characterized in that, back-end support one side arranges wheel, in the middle of wheel inner housing, it is open circles, between wheel inner casing and wheel rim, bearing is set, wheel rim border is coated tire, described wheel split left and right arranges, corresponding support is divided into left socle and right support and is rotationally connected by folding shaft and chassis, described wheel inner casing is divided into left shell and right shell body, described wheel rim is divided into revolver circle and right wheel rim, described tire is divided into left carcass and right carcass, separated about when folding, corresponding left shell, revolver circle and right shell body, the position of right wheel rim arranges respectively bearing, described left shell and left socle are one-body molded, described right shell body and right support are one-body molded, described in during expansion, left socle and right support are merged into an integral support, described chassis arranges tightens up position-limited trough, be used for clamping left socle and right support, between described left socle and right support, spring is set.
Beneficial effect: merge into one when the utility model is used and rotate flexibly without spoke, without hollow whole wheel of wheel shaft, own wt is light, and when folding, wheel divides body deformability, and degree of shrinkage is high, and folding volume is little.

The specific embodiment:
As shown in the figure, the hollow wheel assembly of a kind of split combination type, it is characterized in that, back-end support one side arranges wheel 7, in the middle of wheel 7 inner housings, it is open circles, between wheel inner casing and wheel rim, bearing is set, wheel rim border is coated tire, described wheel 7 split left and right settings, corresponding support is divided into left socle 9 and right support 10 and is rotationally connected by folding shaft 8 and chassis 3, described wheel 7 inner casings are divided into left shell 13 and right shell body 14, described wheel rim is divided into revolver circle 18 and right wheel rim 19, described tire is divided into left carcass 4 and right carcass 5, separated about when folding, corresponding left shell 13, revolver circle 18 and right shell body 14, the position of right wheel rim 19 arranges respectively bearing, described left shell 13 and left socle 9 are one-body molded, described right shell body 14 and right support 10 are one-body molded, described in during expansion, left socle 9 and right support 10 are merged into an integral support, described chassis 3 arranges tightens up position-limited trough 12, be used for clamping left socle 9 and right support 10, between described left socle 9 and right support 10, spring 11 is set.
During vehicular drive, the inner housing of support and wheel 7 is fixed, and owing between inner housing and wheel rim, bearing being installed, wheel rim drives tire to rotate with respect to inner housing, thereby is designed to driven hollow wheels.
Left shell 13 and right shell body 14 are merged into a solid wheel inner casing in use, and revolver circle 18 and right wheel rim 19 are merged into a whole wheel rim, and left carcass 4 and right carcass 5 are merged into an one piece tyre.Do not changing under the prerequisite of original trailing wheel open circles single wheel design, can realize folding time-division body deformability, by a single wheel (comprising support), be divided into two, can be separated into the both sides of front-wheel.
During turnover wheel 7, left and right support can be to the two ends translation gliding of folding shaft 8, and operator can manually assist, and to both sides, breaks into two with one's hands; Also the translation slideway of left and right support can be set in folding shaft 8, translation slideway be set and in turnover, can realize left and right support naturally separately.The length requirement of left and right support has turned down the both sides that rear left carcass 4 and right carcass 5 just move to front-wheel, realizes three left and right and leans on mutually side by side, to reduce largely, takes up an area space.Described chassis 3 arranges tightens up position-limited trough 12, for clamping left socle 9 and right support 10, prevents from using state left and right support to break up the family; When folding, left and right support overturns forward, from tighten up position-limited trough 12, deviates from, and left and right support just can separate.
Between described left socle 9 and right support 10, spring 11 is set, it is compressed using state spring 11, and left and right support leans on side by side mutually; When left and right support overturns forward disengaging position-limited trough, Compress Spring 11 is released, and left and right support is automatically separated under elastic force effect.
Folded bicycle also comprises carrier 1, and it is connected by linkage support axle with chassis 3, the two can folded closed together, carrier 1 arranges front-wheel support 6, front-wheel support 6 arranges front-wheel wheel.Front-wheel support 6 connects steering shaft, and carrier 1 drives front-wheel to realize and turns to.Seat pipe 2 is connected by rotating shaft 15 with chassis 3, and seat pipe 2 can be realized pulling open and closure of vertical direction with respect to chassis 3.In carrier 1, battery can be set, battery is hidden, and does not affect vehicle volume and outward appearance, and Stability Analysis of Structures is reliable, deposits safety.
Described saddle is arranged with through hole in 17 centres, while riding, can ventilate, and avoids driver's hip position to save bit by bit heat and causes discomfort, when there is ponding the rainy day, also can avoid ponding, and the speed of drying is fast.
Under vehicle riding condition, wheel lands, angle approximately at 45 ° between seat pipe 2 and chassis 3, seat manage 2 and carrier 1 between angle approximately at 45 °, between chassis 3 and carrier 1 approximately at an angle of 90.During vehicle folding, seat pipe 2 directions towards carrier 1 merge, and seat pipe 2 be take rotating shaft 15 as axle center, then the direction towards carrier 1 merges by chassis 3, seat pipe 2 is with chassis 3 upward movements, until carrier 1, seat pipe 2, chassis 3 threes are mutually closed between two.
It is pointed out that above-mentioned embodiment is only the preferred embodiment of the invention, for those skilled in the art, meeting under the prerequisite of principle of work of the present invention, any be equal to or similar replacement all falls within the scope of protection of the present invention.
