Description
Technical field
The present invention relates to the manufacture field of all-steel radial tyre, particularly relate to and a kind ofly adjust all-steel radial tyre of tyre bead ladle structure and preparation method thereof.
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 obtains the development be exceedingly fast, and has become the main product of tire industry.But the performance and used life affecting tire that tyre bead problem can be serious in all-steel radial tyre driving process, thus 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 radially arranges, and sidewall is then 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 the rigidity in order to ensure tyre bead, improve the rideability of tire, tyre bead portion must be strengthened, and make to have between tyre bead and the sidewall of softness a suitable rigidity excessive simultaneously, prevent that stress is concentrated, improve the rideability of tire.
China's tyre industry through 20 years, by introducing and digest and assimilate external outstanding technology, has defined 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 transport is developed to high tonnage, heavy-load automobile at a high speed by the autotruck of low tonnage, low speed; Developed to payload of freight container by the load-carrying of bulk goods formula; Transported by high density short range and develop to the long distance of high density or extra long distance, 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 performance difference obvious elastomeric material compositions, 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, near the radial carcass cord sizing material that its end points hardness in bead apex is low after steel bead wire bottom reversed layer by layer, there is the rim of the mouth wirecord fabric enhancement Layer of one deck bottom steel bead wire in carcass ply outside layer by layer, fiber/rubber combined enhancement Layer is had outside the wirecord fabric enhancement Layer of rim of the mouth.
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, composite bead bead apex, casingply is provided with outside wire bead and composite filled adhesive tape, rim of the mouth steel wire infantees is provided with outside casingply, 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 outside the steel wire infantees of rim of the mouth.Be provided with end-blocking adhesive tape above casingply anti-package end points and the outer end points of rim of the mouth steel wire infantees, end-blocking adhesive tape is by complete for end points outside casingply anti-package end points and rim of the mouth steel wire infantees coated closed.The rim of the mouth that the utility model is taked is strengthened mode and is strengthened the region of bead most fragile emphatically but not strengthen the entirety of tyre bead portion, and the bulk strength of bead area increases appropriateness thus ensure that the impact in service life of shoulder zone less.
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 being pushed down by carcass anti-package end points, steel wire heel fabric and steel wire heel fabric U-shaped encapsulated by structures rim of the mouth place carcass, rim of the mouth intensity can be increased like this, stop rim of the mouth Problems existing.And rim of the mouth adopts U-shaped packet form, carcass anti-package end points is pushed down, and adopt 15 degree of angles, rim of the mouth steel wire is soft simultaneously, instead of as carcass 90 degree, end points is also neat, and 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 gradually excessively, rim of the mouth can be made to split to reel off raw silk from cocoons with rim of the mouth greatly to improve, extend service life, saved resource.
All-steel radial tire quality problems have very most of quality problems for tyre bead portion, and this is also one of significant technology issues of facing of domestic and international tire enterprise, and the present invention is just based on the achievement of the market demand and enterprise's long-term technology tackling key problem.

After testing, the present invention has following effect:
One, this invention can significantly improve the bead durability energy of tire
Project organization tire of the present invention is compared with original structure tire, and actv. improves the bead durability energy of all-steel radial tyre.At standard load 200%, under the condition of standard pressure 80%, the present invention's design and former designing tyre carry out repeatedly twice load bead durability and to test.Machine tool data contrast is as follows:
| Bead durability can be tested | First time contrast | Second time contrast | Third time contrast |
| Standard tire | 7h44min | 5h34min | 5h11min |
| Design experiment tire of the present invention | 15h07min | 13h22min | 14h32min |
By the lathe correlation data that the tyre bead of 200% load is durable: the twice load tyre bead of standard tire is durable is 5 ~ 7h; Designing tyre of the present invention is durable is 14 ~ 15h, and bead durability actv. improves 30% ~ 50%.Pay compensation for rate due to the machine tool data of tire and product and have good conformability, therefore this programme is after operation, the tyre bead of enterprise is paid compensation for and is expected to reduce by 50%, and this brings huge economic benefit by for enterprise.
Two, the anti-top load performance of reinforced bead, improves tyre bead safety
The quality accident 40% of automobile comes from tire, and tyre bead odd test is fried is also one of typical defect in home market, and this invention design strengthens the anti-of tyre bead and carries performance, effectively can reduce the quality accident because tire causes, and ensures the security of the lives and property of user.
Three, the refresh rate of tire is improved
Bead distortion are one of main symptom affecting tyre rebuilding recycle, and the outer enhancement Layer ladle structure that the present invention adopts effectively can suppress the torsional deformation of tyre bead under high load capacity, significantly improves rate of reoperative tyre, is conducive to realizing recycle, environmental protection.
