The specific embodiment

See also Fig. 1, Fig. 2, airless tire pressure feedway of the present utility model is to comprise an annular solid 10, generally with Ref. No. 10 expressions; In the embodiment that is adopted, annular solid 10 is an annular plate-like configuration, becomes the kenel of symmetry.The two ends of annular solid 10 have the less connecting portion of

thickness

11,12, articulate

fixed part

20,30 respectively.Be to show that this connecting

portion

11,12 is to be connected with fixed

part

20,30 through

fixer

40,41 among the figure.

In a preferred embodiment, these fixed part 20 cordings have a groove chamber 21, hold an elastic component 50 and fixer 40; Therefore, the end that Fig. 3 demonstrates this elastic component 50 is the wall 22 that leans against groove chamber 21, and other end system is fixed on the fixer 40.The 3rd figure also demonstrates and has kept a gap x between fixed part 20 and the annular solid 10, and 10 1 motions of annular solid or fine motion space (this part also can be narrated hereinafter) are provided.

One Flexible element 60 in the embodiment that is adopted, is that this annular solid 10 forms symmetrical kenel relatively; Have one first end 61 and one second end 62, be separately fixed on this annular solid 10 and the wheel rim 70.Second end 62 of Flexible element 60 is to dispose an adjustable bolt 63, can adjust 60 elastic forces between wheel rim 70 and annular solid 10 of this Flexible element.

In a feasible embodiment,, on this fixed part 30 a configurable counterweight 80 for the weight of balance fixed part 20 and Flexible element 60.Fig. 3 also depicts especially, in a preferred embodiment, also disposes a counterweight 80 on each annular solid 10, allows each weight partly of this bracing or strutting arrangement can form state of equilibrium.

The bracing or strutting arrangements that part constituted such as annular solid 10, fixed

part

20,30, Flexible element 60 have been described by Fig. 3, Fig. 4 system, with the configuration scenario of wheel rim 70, air-free tyre 90.This annular solid 10, fixed

part

20,30 are to be set between the space y that this tire 90 and wheel rim 70 defined; And, second end 62 of this Flexible element 60 is fixed on the wheel rim 70.Also having disclosed a pressure gauge 71 among the figure is that detouchable is fitted on the wheel rim 70, is used for showing the pressure situation of this wheel rim 71.

Please refer to Fig. 5, Fig. 6, annular solid 10, fixed

part

20,30 and Flexible element 60 etc. partly can be along with wheel rim 70 and tire 90 rotate; Particularly when tire 90 kiss the earths, can produce an antagonistic force and make annular solid 10 fine motion in the x of this gap; For example, the shown situation of Fig. 6.

The arrow of Fig. 6 partly shown when tire 90 when the direction of clockwise is rotated, annular solid 10 can this Flexible element 60 of pushing, for example situations that imaginary line is partly described among the figure.Simultaneously, annular solid 10 also promotes to be arranged on fixer 40 compression elastic pieces 50 on the annular solid connecting portion 11; Cooperate the motion of annular solids 10 to produce the effect of elasticity convergent-divergent via Flexible element 60 and elastic component 50, and set up one jointly when annular solid 10 is rotated with tire 90, but the mechanism of the support tire 90 of elasticity fine motion is slowed down or eliminated shaking force when taking action.In a feasible embodiment, between wheel rim 70 and tire 90, also can be filled gas, increase its elasticity convergent-divergent effect.

Typically, this airless tire pressure feedway system is to be different from the structure design of prior art, and the phase can directly replace the tire pressure supply of inflatable tire originally, or also can be used as airtyred tire pressure auxiliary security function; Really the function for not had in the old law is to have represented sizable progress, has filled the important document that part meets utility model patent.

Only, the above person is a possible embodiments of the present utility model only, is not to be used for limiting the scope that the utility model is implemented, and promptly all equalizations of being done according to the utility model claim change and modify, and are all the utility model claim and contain.
