Description
Technical field
The present invention relates to a kind of radial tyre bead, particularly relate to the tyre bead of a kind of all-steel radial tyre, belong to wheel
Tire manufacturing technology field.
Background technology
The bead structure of existing all-steel radial tyre, including inner side hard triangular rubber core, the soft triangular rubber core in outside, tire
Wirecord fabric, bead adhesive, sidewall rubber, nylon curtain face and inner liner are strengthened in body cord, rim of the mouth.Owing to the management of current road conditions is not advised
Model, and the behaviour in service such as vehicle often overloads seriously, air pressure is higher, therefore require higher to the tire of vehicle.And as often
By the structure of tire, the bead structure support performance of above-mentioned tire is not enough, deformation is relatively big, and bends in rim flange, wheel
Near rim lug area, the anti-package carcass ply of position, rim of the mouth are strengthened wirecord fabric compression, are easily formed stress concentration, thus
Cause tire that the quality problems such as circle empty, circle splits, explosion occur.
Summary of the invention
For the above-mentioned problems in the prior art, the invention provides a kind of warping strength deformation and there is preferably support
The radial tyre bead of performance.
The present invention is achieved by the following technical solution: a kind of radial tyre bead, including being wrapped in tyre bead
The inner liner of side, carcass ply, rim of the mouth reinforcement wirecord fabric, it is wrapped in the bead adhesive outside tyre bead and sidewall rubber, it is characterized in that:
Also include that three compound adhesive cores, described three compound adhesive cores include filling glue core, hard triangular rubber core, soft triangular rubber core, described hard triangle
Glue core is positioned at inner side, and described soft triangular rubber core is positioned at outside, and described filling glue core is positioned at the close tyre bead of described hard triangular rubber core
The side of inner side, described filling glue core, hard triangular rubber core, soft triangular rubber core are strengthened by carcass ply and rim of the mouth the most successively
Wirecord fabric wraps up.
The present invention is by using three compound adhesive cores of particular design, and (rigidity increases can to promote tyre rim position support performance
Adding, support performance increases), and improve tyre bead position under high loading condition deflect rigidity.
Further, in order to promote tyre rim position support performance further, and tyre bead position under high loading condition is improved
That puts deflects rigidity, posts the carcass ply inside by tyre bead and rim of the mouth between the carcass ply inside described inner liner and tyre bead
Strengthen the double-deck aromatic polyamide cord of termination, wirecord fabric upper end infantees.Preferably, the angle of described double-deck aromatic polyamide cord is 25-35 degree,
Width is 80-120 millimeter, ectonexine stagger poor level 10-15 millimeter intersect laminating.
Further scheme is, steel wire is strengthened in rim of the mouth inside tyre bead, the lower extreme point position of described double-deck aromatic polyamide cord
The termination, upper end of cord is 25-50 millimeter.The program can be prevented effectively from rim of the mouth, inner side reinforcement steel cord upper extreme point stress concentration and make
The earlier period damage become.
Carcass ply and rim of the mouth outside sidewall rubber, tyre bead are strengthened posting the rim of the mouth outside by tyre bead between wirecord fabric
The double-layer nylon cord that reinforcement wirecord fabric and termination, carcass ply upper end encase.The program can effectively avoid end points stress collection
In the earlier period damage that causes.
Preferably, the angle of described double-layer nylon cord is 30-55 degree, and width is 80-120 millimeter, and ectonexine staggers poor level
The most compliant conjunction of 10-15 millimeter.
For promoting further tyre rim position support performance, and improve deflecting just of tyre bead position under high loading condition
Property, outside tyre bead, the carcass ply described in wirecord fabric parcel is strengthened in described rim of the mouth.
Further, the upper end end points of the wirecord fabric upper end end points away from carcass ply is strengthened in described rim of the mouth is 20-40 milli
Rice, described rim of the mouth is strengthened the upper end end points of wirecord fabric and is surrounded by rim of the mouth reinforcement steel wire bound edge nylon, the upper end of described carcass ply
End points is surrounded by carcass ply bound edge film.
Further, the termination height H1 of carcass ply is: 70mm-90mm, and the end points of wirecord fabric is strengthened in described rim of the mouth
Highly H3 is: 30mm-50mm, and the termination height H2 of described carcass ply bound edge film is: 55mm-75mm, described hard triangle rubber
The base width H4 of core is 18mm-25mm.By improving above-mentioned height H1-H3 and the size of width H4, whole tire can be improved
Circle rigidity.
Described sidewall rubber, the termination height scope of bead adhesive are 60mm-80mm, and rim flange area tire bead position is thick
Degree is 36mm-42mm.By adjusting the termination height of bead adhesive and sidewall rubber, and increase rim flange area tire bead position
Thickness, can reduce flexural deformation.
The invention has the beneficial effects as follows: the present invention, by using three compound adhesive cored structures of particular design, can effectively promote
Tyre rim position support performance, and be effectively improved tyre bead position under high loading condition deflect rigidity；By adopting in inner side
The structure with the intersection laminating of two-layer aromatic polyamide cord, strengthening wirecord fabric parcel carcass ply in employing rim of the mouth, outside and adjustment rim of the mouth
Ebonite position, improves tyre rim position support performance further, and improves deflecting of tyre bead position under high loading condition
Rigidity；Nylon bound edge, carcass ply is used to use film bound edge, carcass ply and son it addition, strengthen steel wire cord by rim of the mouth
Mouth strengthens wirecord fabric anti-package optimization etc., improves the stress dispersibility of each anti-package end points, reduces stress and concentrates tire
The destruction of tyre bead.
