Description
Technical field
The utility model relates to a kind of full steel wire inner tube of a tyre radial-ply tyre, belongs to radial-ply tyre technical field.
Background technology
In actual use, full steel wire tube-tyre will bear periodic load, and carcass anti-package termination or steel wire infantees termination can be moved by occurrence positions under cyclic load effect, cause this place's stress high concentration.Irrational bead designs can aggravate this phenomenon.Typical full steel wire has in inner tube of a tyre radial-ply tyre structure, in bead part, carcass ply walks around anti-package termination that bead coil formed or steel wire infantees termination is areal of stress concentration, tire is in use normal because coming to nothing wirecord fabric termination, and causes the various symptom occurring tire bead earlier period damage.How handling the problem that full steel wire has inner tube of a tyre meridian tyre body curtain cloth anti-package termination and steel wire infantees termination stress to concentrate well, is always one of important goal of tire optimal design pursuit.
Full steel wire has inner tube of a tyre radial-ply tyre conventional tire bead structure more complicated, generally comprises bead coil, carcass ply anti-package termination, steel wire infantees termination.Tire bead is at anti-package termination or position, steel wire infantees termination, and the rigidity of structure exists comparatively macromutation.In tire is exercised, carcass deflects distortion repeatedly, and the sudden change of rigidity will cause position, termination concentrate due to stress and very easily destroy, thus cause tire early damage.The outline of traditional tire cross-section near anti-package structure is evagination camber line structure (see figure 1).
Summary of the invention
The purpose of this utility model is to solve above-mentioned prior art Problems existing, namely how to handle the problem that full steel wire has inner tube of a tyre meridian tyre body curtain cloth anti-package termination and steel wire infantees termination stress to concentrate well.And then provide a kind of full steel wire to have inner tube of a tyre radial-ply tyre.
The purpose of this utility model is achieved through the following technical solutions:
A kind of full steel wire has inner tube of a tyre radial-ply tyre, comprising: carcass ply, carcass anti-package termination and steel wire infantees termination, is provided with narrow groove or wide groove in the outside of the tyre bead on carcass anti-package termination and top, steel wire infantees termination.
Have the shortest distance of the tyre bead appearance profile line of narrow groove or wide groove and steel wire infantees termination and anti-package cord termination all >=5mm.
The utility model is a kind of tire construction of the reeded outline feature of tool near tyre bead anti-package structure, this groove structure making tire bead local reduction, tyre bead can be made to deflect in distortion and to move on to groove area, improve anti-package termination or steel wire infantees end strained condition, significantly reduce cord termination stress concentration phenomenon, thus avoid anti-package termination or position, steel wire infantees termination to lose efficacy.Full steel wire of the present utility model has inner tube of a tyre radial-ply tyre in use, bead part deflect in local reduction's set of regions, significantly reduce the stress concentration of bead part carcass ply anti-package end or steel wire infantees end, thus prevent the earlier period damage of bead part.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under premised on technical solutions of the utility model, gives detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figures 2 and 3, a kind of full steel wire involved by the present embodiment has inner tube of a tyre radial-ply tyre, comprise: carcass ply 1, carcass anti-package termination 2 and steel wire infantees termination 3, be provided with narrow groove 9 or wide groove 10 in the outside of the tyre bead on carcass anti-package termination 2 and top, steel wire infantees termination 3.The present embodiment strengthens the construction of carcass ply anti-package termination, up and down both sides bending stiffness drop by groove structure design.First adjust the position of carcass anti-package termination height and steel wire infantees two terminations, allow carcass anti-package termination and steel wire infantees two terminations end at a line: the summit 6 of rim arc 4 crossed by this line, is 30 degree of angles of cut with the horizon inside wheel rim,
As shown in Figure 2, tyre bead is made to increase with the rigidity of lower area in anti-package termination; Make tire in use bead part deflect distortion concentrate on move on to tyre bead groove thinnest part, strengthen the protection to this termination thus.Have the shortest distance of the tyre bead outlined groove profile line of narrow groove 9 or wide groove 10 and steel wire infantees termination 3 and anti-package cord termination 2 all >=5mm, shorter distance is unfavorable for the protection of elastomeric material to steel wire infantees termination and anti-package cord termination.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 the circle of radius >=5mm is made 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.Except bead part and the common full steel wire of tire have the structure member included by inner tube of a tyre radial-ply tyre consistent except, the bottom portion of groove of the narrow groove 9 of the top tyre bead of carcass anti-package termination 2 or the wide groove 10 of tyre bead and the distance of carcass ply 1 are 3--5mm, the opening height size Approximately of the narrow groove 9 of described tyre bead is three to five times of groove depth, the opening height dimension of wide groove 9 can go directly horizontal shaft 11 position near.The upper edge of groove, its groove walls curve arc answers smooth excessiveness to tyre bead surface outline curves (see Fig. 2, Fig. 3).Tire in use, the lower edge less than 7 of groove all the time with bead-protecting rim close contact, the groove design on it then avoids the contact of tyre bead and rim, and this has just fundamentally stopped the appearance of bead wall rubber surface part wear problem.
The above; be only the utility model preferably detailed description of the invention; these detailed description of the invention are all based on the different implementations under the utility model general idea; and 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, protection domain of the present utility model should be as the criterion with the protection domain of claims.
