Abstract
The open a kind of inflation diagonal tyre of the utility model, tire carcass comprises internal surface layer, carcass layer, cushion layer from inside to outside, tyre surface circumference line of centers is provided with the first main line, and does shallow ridges design, be provided with circumferential fine groove in the both sides of this main line; Second main line is respectively provided with in the outside of each described fine groove; The degree of depth of described first main line is less than the degree of depth of the second main line; The degree of depth of described first main line is 2-4.5mm; Distance between adjacent two the second main line line of centerss is the 40%-70% of tread width; The width of described cushion layer is greater than the distance between adjacent two the second main line line of centerss, and is less than or equal to 70% of tread width.The utility model can make the radial direction of crown part grow up and be buffered layer constraint, and after inflation, growth makes its tyre surface radian become large, is conducive to improving manipulation stability, but the course continuation mileage of vehicle is also influenced.In addition, crown center main groove arranges the handling that ensure that wetland.
Description
Technical field
The utility model relates to a kind of air-inflation tyre, particularly relates to a kind of inflation diagonal tyre of low aspect ratio.
Background technology
In recent years, because the performance of existing electronlmobil improves constantly, all propose more and more higher demand to speed and course continuation mileage, the manipulation stability requirement therefore for its supporting tire is also higher.Compare common tire, the manipulation stability of low flat tire can be better, but after its inflation, crown position distortions is comparatively large, particularly considers for wetland performance, generally arranges circumferential main line at crown center.Which increase the distortion of crown, the ground contact area of tire is significantly reduced, thus have influence on manipulation and wear hardness.For solving this contradiction, usually between tyre surface and carcass, arrange cushion layer, in order to strengthen tyre surface rigidity and constraint carcass, reduce the distortion of crown center, in general, carcass cushion layer width exceedes whole tread width.Though way like this can solve above-mentioned puzzlement, the course continuation mileage having influence on again vehicle because ground contact area is excessive.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of inflation diagonal tyre, and it can suppress the distortion of crown, thus improves the manipulation stability of tire and the course continuation mileage of lifting vehicle, and takes into account wetland performance.
For achieving the above object, one inflation diagonal tyre described in the utility model, tire carcass comprises internal surface layer, carcass layer, cushion layer from inside to outside, tyre surface circumference line of centers is provided with the first main line, is provided with circumferential fine groove in the both sides of this main line; Second main line is respectively provided with in the outside of each described fine groove; The degree of depth of described first main line is less than the degree of depth of the second main line; The degree of depth of described first main line is 2-4.5mm; Distance between adjacent two the second main line line of centerss is the 40%-70% of tread width; The width of described cushion layer is greater than the distance between adjacent two the second main line line of centerss, and is less than or equal to 70% of tread width.
Preferably, described cushion layer adopts single or multiple lift to arrange.
The beneficial effects of the utility model are:
The width of the utility model employing shallow ridges design and cushion layer is greater than the distance between adjacent two the second main line line of centerss, and be less than or equal to 70% of tread width, the radial direction of crown part is grown up and is buffered layer constraint, and growth makes its tyre surface radian become large after central gas, be conducive to improving manipulation stability, and consider the course continuation mileage of vehicle, and crown center first main line arranges the handling that ensure that wetland simultaneously.
Accompanying drawing explanation
Fig. 1 is the tyre surface expansion drawing of inflating diagonal tyre described in the utility model embodiment;
Fig. 2 is the cross-section cutaway view inflating diagonal tyre described in the utility model embodiment.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1 and Figure 2, described in the utility model embodiment, a kind of inflation diagonal tyre, the circumferential line of centers of its tyre surface 6 is provided with the first main line 4, and above-mentioned main line does shallow ridges design, is provided with circumferential fine groove 7 in the both sides of this main line; Second main line 5 is respectively provided with in the outside of each described circumferential fine groove 7.The degree of depth h1 of described first main line is less than the degree of depth h2 of the second main line; The degree of depth h1 of described first main line is 2-4.5mm.The rigidity that this kind of design not only makes tyre surface centre keep higher, and the wetland performance of tire can be ensured and suppress the distortion of center ditch, thus reach the effect promoting manipulation.Distance L1 between the line of centers 11,22 of another adjacent two the second main lines 5 is the 40%-70% of tread width W.If above-mentioned distance L1 is excessive, ground contact area can be caused to become large, thus affect the course continuation mileage of vehicle; If above-mentioned distance L1 is too small, ground contact area can be caused to diminish, cause manipulation stability to decline.Tire carcass comprises internal surface layer 1, carcass layer 2, cushion layer 3 from inside to outside, described cushion layer 3 adopts single or multiple lift to arrange, the width L2 of described cushion layer 3 is greater than the distance L1 between adjacent two the second main line 5 line of centerss, and is less than or equal to 70% of tread width W.If above-mentioned length L2 is too small or excessive, all have influence on the ground contact area of tire, cause partial properties to decline.
First main line 4 described in the utility model adopts shallow ridges to design effectively suppression tyre surface 6 distortion after inflation, in addition the constraint of cushion layer 3, make tyre surface radian become large, be conducive to improving tire wear performance and manipulation stability, improve the course continuation mileage of vehicle and the handling of wetland.
Above; be only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
