Description
Technical field
The present invention relates to tire, and in particular to a kind of air tyre.
Background technology
There are three kinds of tires for being different from pneumatic tire in the prior art.One kind is by general cover tire and PU foaming inner tube of a tyre structures
Into this tire can possess normal tire earth-grasping force and wearability, and shortcoming is exactly that bearing butter can melt after being toasted through wheel group
Or loss, influence wheel group rotates smoothness, and the overall size of the PU foaming inner tubes of a tyre possesses higher size requirement, depending on cover tire and
The dimensions of wheel rim.Another is pure foaming tire, and this foaming tire possesses solid carcass, and connection tread contour is all once
Property is made.But this tire section possesses many spileholes, and tyre surface also possesses spilehole simultaneously, so that not wear-resisting.Another is
PU honeycomb tyres, same wearability is not as good as existing air tyre, and cost is higher.
The content of the invention
The problem to be solved in the present invention is to provide a kind of air tyre, reduces and safeguard, possesses anti-stamp function, and saving carcass makes
It is easy to assembly with wheel rim with material.
To solve the above problems, the present invention provides a kind of air tyre, to reach above-mentioned purpose, the present invention solves its technology and asked
Inscribing used technical scheme is：
A kind of air tyre, including crown, carcass, tire toe；Wherein：Running through in carcass has cavity；It is characterized in that：The tire
The cavity accounting cross section gross area is 20% to 50% in body cross section.
It is using the beneficial effect of above-mentioned technical proposal：The present invention is without inflating, safeguarding less, possess anti-stamp function.Carcass
Material can use grade same with the cover tire of conventional tyre of the prior art rubber, can possess together with existing cover tire
The wearability of sample, and carcass thickness is thick, it is equivalent to possess thicker wearing layer, possess more long usage cycles.Carcass thickness is big
Determine that it is difficult to be pierced through by sharp object.
The hollow cavity area accounting 20% to 50% in carcass cross section is the result learnt after proving repeatedly, if being less than
20% cavity is too small, then rubber consumption is excessive, causes air tyre hardness higher；Cavity is excessive if higher than 50%, carcass
Support system is excessively thin, is not enough to support vehicle body.
As a further improvement on the present invention, the cavity cross-sectional profile is oval.
It is using the beneficial effect of above-mentioned technical proposal：Elliptical shape is more succinct, and technological requirement is low.
As the present invention further improvement, the cavity cross-sectional profile be a major arc, a minor arc and major arc with
The closed figure that two common tangents between minor arc are surrounded.
It is using the beneficial effect of above-mentioned technical proposal：Two common tangents and the distance between carcass outline are larger, i.e.,
Tyre sidewall thickness is relatively large there is provided stronger tyre sidewall support, prevents that air tyre from collapsing deformation.
As the further improvement of the present invention, the limited impression coordinated with wheel rim is provided between the tire toe and carcass.
It is using the beneficial effect of above-mentioned technical proposal：It is easy to air tyre to be fixedly secured with wheel rim.
As the further improvement of the present invention, possesses circumferential slot on the tire toe.
It is using the beneficial effect of above-mentioned technical proposal：Circumferential slot provides deformation retract space to tire toe, is easy to tire toe
Filled in after appropriate deformation in wheel rim, reach the assembling with wheel rim.
As the further improvement of the present invention, passage is connected between the circumferential slot and cavity.
It is using the beneficial effect of above-mentioned technical proposal：The load-bearing capacity of air tyre is almost given by its thick-walled structure completely
, when tire sinks under a load, in order that its cavity internal pressure remain zero, it is necessary to tire some point on there is one to pass through
The aperture of tyre surface.When air tyre is run, air tyre compressive deformation, cavity volume change, air turnover passage plays convection current
Radiating, reduces tire overheating deforming.Circumferential slot also functions to the effect for preventing that passage is blocked.
As the further improvement of the present invention, possesses ring-type muscle on the cavity inner wall.
It is using the beneficial effect of above-mentioned technical proposal：Ring-type muscle strengthens air tyre on the basis of playing saving carcass material
The effect of structure.
As the further improvement of the present invention, the wearability of the crown material is higher than carcass material therefor.
It is using the beneficial effect of above-mentioned technical proposal：The high-wearing feature of crown improves the service life of air tyre.
As the further improvement of the present invention, possess at least one color on the crown and distinguish band, the chromatic zones
The thickness of band is divided to be less than the thickness of crown.
It is using the beneficial effect of above-mentioned technical proposal：Because the thickness that color distinguishes band is less than crown, in use, color
Distinguish band to be worn totally prior to crown, color distinguishes the effect for taking up the prompting crown degree of wear.
As the further improvement of the present invention, possess on the tire toe on fillet, the tire toe close to limited impression
Fillet is less than the fillet away from limited impression.
It is using the beneficial effect of above-mentioned technical proposal：Tire toe Rouno Cormer Pregrinding Wheel facilitates tire toe to be embedded in wheel rim, is taken turns when tire toe loads
After circle, tire toe small round corner plays a part of limitation tire toe and extracted from wheel rim.
