Technical field
The utility model relates to the manufacture field of all-steel radial tyre, relates in particular to a kind of all-steel radial tyre of adjusting tyre bead ladle structure.
Background technology
Along with developing rapidly of auto-industry, more and more higher to the requirement of tyre performance, so compared with bias tire, the all-steel radial tyre with good wear-resisting fuel-economizing has obtained the development being exceedingly fast, and become the main product of tire industry.But the performance and used life that affects tire that tyre bead problem can be serious in all-steel radial tyre driving process, thereby the design improvement of bead structure has become one of main construction of domestic and international each giant tyre enterprise.The body cord of radial-ply tyre is radial array, and sidewall is more soft, and in tire running process, tyre bead is stressed very large, less stable, and the ability of tyre bead portion opposing high load capacity is lower.Under high-load condition, often there is the situation such as breach, distortion in tyre bead portion, so in order to guarantee the rigidity of tyre bead, improve the rideability of tire, tyre bead portion must be strengthened, and make have a suitable rigidity excessive between tyre bead and soft sidewall simultaneously, and prevent that stress concentrates, improve the rideability of tire.
China's tyre industry through 20 years, by introducing and digest and assimilate external outstanding technology, has formed huge productive capacity at all steel load radial tire production field since late 1980s.The current tire output of China is large, specification is many, but the homogeneity of all-steel load-bearing radial tire is serious, and the quality of product needs to improve.
Along with the economic development of China, the transportation of China is also developing rapidly.Meanwhile, the development model of highway in China transportation is developed to the heavy-load automobile of high tonnage, high speed by the autotruck of low tonnage, low speed; Developed to payload of freight container by the load-carrying of bulk goods formula; Developed to the long distance of high density or extra long distance by high density short range transportation, this must expand the field of application of all steel load radial tire.
Chinese utility model patent (application number: 02234433.0 applying date: 2002-05-10) discloses a kind of reinforcing structure for seam allowance of full steel wire heavy load radial tire, mainly contain steel bead wire, the composite filled adhesive tape of two kinds of obvious elastomeric material compositions of performance difference, radial carcass cord layer by layer, bead wirecord fabric enhancement Layer and fiber/rubber combined enhancement Layer composition, it is characterized in that, from tire section, steel bead wire top is by two kinds of composite filled adhesive tape that the obvious elastomeric material of difference forms in hardness, radial carcass cord layer by layer after steel bead wire bottom reversed its end points near bead apex near the low sizing material of hardness, there is the rim of the mouth wirecord fabric enhancement Layer of one deck through steel bead wire bottom in carcass ply outside layer by layer, there is fiber/rubber combined enhancement Layer in rim of the mouth wirecord fabric enhancement Layer outside.
Chinese utility model patent (application number: 200820149422.5 applyings date: 2008-09-25) discloses a kind of radial tire deadblow out portion reinforcing structure of all-steel load radial tire, comprise wire bead, compound tyre bead bead apex, be provided with casingply outward in wire bead and composite filled adhesive tape, casingply is provided with rim of the mouth steel wire infantees outward, casingply anti-package end points, higher than the outer end points of rim of the mouth steel wire infantees, has the wear-resisting glue in one deck rim of the mouth and sidewall rubber outward at rim of the mouth steel wire infantees.The outer end points of casingply anti-package end points and rim of the mouth steel wire infantees top is provided with end-blocking adhesive tape, and end-blocking adhesive tape is by casingply anti-package end points and the completely coated sealing of the outer end points of rim of the mouth steel wire infantees.The rim of the mouth reinforcement mode that the utility model is taked is strengthened emphatically the region of bead most fragile but not the entirety of tyre bead portion is strengthened, and has guaranteed the impact in service life of shoulder zone less thereby the bulk strength of bead area increases appropriateness.
Chinese invention patent (application number: 201310113155.1 applyings date: 2013-04-03) discloses heavier-duty load-carrying whole steel wire radial tyre, carcass outside, rim of the mouth place is provided with the double-deck heel fabric for carcass anti-package end points is pushed down, steel wire heel fabric and steel wire heel fabric are U-shaped encapsulated by structures rim of the mouth place carcass, can increase like this rim of the mouth intensity, stop the problem that rim of the mouth exists.And rim of the mouth adopts U-shaped packet form, carcass anti-package end points is pushed down, and is adopted 15 degree angles, simultaneously rim of the mouth steel wire softness, rather than spend as carcass 90, end points is also neat, rigidity is too strong, excessively not smooth, by hard steel wire once excessively to soft sizing material.After like this improving now by firmly to soft excessive gradually, can make rim of the mouth split and the rim of the mouth improvement greatly of reeling off raw silk from cocoons, extended service life, saved resource.
