Abstract
The invention provides an all-steel-cord tubeless radial tire with bead filler arranged outside and belongs to the technical field of tubeless radial tires. The tubeless radial tire comprises a carcass ply and a carcass turn-up end, wherein a narrow groove or a wide groove is formed in a tire bead above the carcass turn-up end, and the lower edge of the narrow groove or the wide groove is positioned at the apex of a rim contour edge curve arc. According to the all-steel-cord tubeless radial tire with the bead filler arranged outside, the groove is designed near the upper side of the carcass turn-up end of the tire bead, and the lower edge of the groove forms a boundary which can determine whether the side of the tire bead and a rim are contacted or not. During usage of the tire, the part below the lower edge of the groove is always closely contacted with the rim, and the surface of the groove is prevented from being contacted with the rim edge due to the design of the groove, so that the problem of wear of surface rubber parts on the side of the tire bead is fundamentally solved, and the service life of the tire is greatly prolonged.
Description
Technical field
The present invention relates to the tubeless meridian tire that a kind of full steel wire triangle rubber is external, belong to tubeless meridian tyre technology.
Background technology
The tubeless meridian tire that full steel wire triangle rubber is external and common standard wheel rim is supporting installs and uses.Although the bead structure of this tire is special, it does not have steel wire infantees, carcass anti-package termination is close to outside carcass ply, the problem that carcass ply anti-package termination stress is concentrated can be effectively prevent, but because the tubeless meridian tire that this full steel wire triangle rubber is external have employed the design of Tai Quan Of-thin body, the thinner thickness at tire bead position, amplitude of deformation is deflected large in tire running, when tyre bead deflects distortion repeatedly, there is the annular region of a width only about 20mm in surface near wheel rim and beads contact edges of regions, contact with rim once enclosing with per tyre turn, be separated once, fast this, contact frequently, in separation process, rubber components in the annular region of tyre bead surface degree only about 20mm and producing between rim slides, friction, inevitably there is severe wear, cause tire earlier period damage.
Summary of the invention
The object of the invention is to solve above-mentioned prior art Problems existing, namely when tyre bead deflects distortion repeatedly, there is the annular region of a width only about 20mm in surface near wheel rim and beads contact edges of regions, contact with rim once enclosing with per tyre turn, be separated once, contact fast, frequently, in separation process this, rubber components in the annular region of tyre bead surface degree only about 20mm and producing between rim slides, rubs, inevitably there is severe wear, cause tire earlier period damage.And then the tubeless meridian tire providing a kind of full steel wire triangle rubber avoiding this damage external.
The object of the invention is to be achieved through the following technical solutions:
The tubeless meridian tire that a kind of full steel wire triangle rubber is external, comprise: carcass ply and carcass anti-package termination, tyre bead above described carcass anti-package termination is provided with a narrow groove or wide groove, and the lower edge position of described narrow groove or wide groove fixes on the summit place of rim contour boundary curve arc.
The present invention be above the carcass anti-package termination of tyre bead near be designed with the external tubeless meridian tire of the full steel wire triangle rubber of a groove, the lower edge of groove forms the demarcation line whether bead wall contacts with wheel rim.Tire in use, below the lower edge of groove all the time with wheel rim close contact, groove design on it avoids the contact of groove surfaces and rim, has fundamentally stopped the appearance of bead wall rubber surface part wear problem, thus has greatly extended the service life of tire.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented under premised on technical solution of the present invention, gives detailed embodiment, but protection scope of the present invention is not limited to following embodiment.
As shown in Figures 2 and 3, the tubeless meridian tire that a kind of full steel wire triangle rubber involved by the present embodiment is external, comprise: carcass ply 1 and carcass anti-package termination 2, tyre bead above described carcass anti-package termination 2 is provided with a narrow groove 5 or wide groove 9, the lower edge position of described narrow groove 5 or wide groove 9 fixes on summit 6 place of rim contour boundary curve arc 4.
The present embodiment be above the carcass anti-package termination of tyre bead near be designed with the external tubeless meridian tire of the full steel wire triangle rubber of a groove, the lower edge of groove forms the demarcation line whether bead wall contacts with wheel rim.Tire in use, below the lower edge of groove all the time with bead-protecting rim close contact, the groove design on it avoids the contact of groove surfaces and rim, has fundamentally stopped the appearance of bead wall rubber surface part wear problem.When implementing design (see Fig. 2 and Fig. 3), the lower edge position of groove fixes on the summit 6 of rim contour boundary curve arc 4, with carcass anti-package termination 2 outward flange point for making the circle that radius is 7mm in the center of circle, this circle outside tangent line is made on the summit 6 crossing wheel rim contour edge curve arc 4, is tangential on the end points 8 of groove linear portion wall portion profile; The lower edge 7 of groove is that the lower edge of groove designs for the interference of wheel rim with lower curve.Groove walls outline line is built with the arc of several sections of smooth connections from the end points 8 of groove linear portion wall portion profile, except the structure member included by the full steel wire tubeless meridian tire that the bead part of tire is external with common triangle rubber is consistent, the narrow groove 5 in upper end of carcass anti-package termination 2 or the bottom portion of groove of wide groove 9 and the distance of carcass ply 1 are 3 ~ 5mm, and described narrow groove 5 Kai mouth Chi Cun Approximately is 3 ~ 5 times of groove depth; The opening height dimension of wide groove 9 can near the flat shaft position of direct steamer fetal fluids.The upper edge of groove, its groove walls curve arc answers smooth excessiveness to tyre bead surface outline curves (see figure 2).The lower edge less than 7 of groove all the time with wheel rim close contact, the groove design on it then avoids the contact with rim, and this has just fundamentally stopped the appearance of bead wall rubber surface part wear problem.
The above; be only the present invention's preferably detailed description of the invention; these detailed description of the invention are all based on the different implementations under general idea of the present invention; and protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
