The specific embodiment
The utility model embodiment provides a kind of improved tire of bead structure that has, and can significantly improve load-carrying properties, anti-fatigue performance and the service life of tire, thus guarantee driving safety.
Refer to Fig. 1, in the utility model embodiment, there is the improved tire embodiment of bead structure and comprise:
Crown 101, crown comprises tyre surface and crown reinforcement;
102， sidewall, sidewall extends radially inwardly crown;
Tyre bead 103, tyre bead 103 comprises: enhancement Layer 1, enhancement Layer 2 1032, bead coil 1033, support glue 1034 and body piles 1035;
Enhancement Layer 1 wraps in the outside of bead coil 1033, support glue 1034 and body piles 1035 in U-shaped mode, the outer end points of enhancement Layer 1 and body piles 1035 endpoint locations radially stagger, and the interior end points of enhancement Layer 1 is positioned at and supports glue 1034 downsides or inner side;
The upper extreme point of enhancement Layer 2 1032 is positioned on the outer end points of body piles 1035 end points and enhancement Layer 1, and its lower extreme point is sandwiched in the turn-up section of body piles 1035 and supports between the outside of glue 1034;
One end of body piles 1035 is positioned at bead coil 1033 bottoms, and with the mode wrapped wire circle 1033 that overturns, its end points anti-package is to supporting glue 1034 outsides.
The scope of the bead seat angle β of above-mentioned tire is between 0 ° to 30 °, and being preferably equipped bead seat angle is the tire of 5 ° or 15 ° standard rims, for example, can be fitted on the tubeless rim that has inner tube of a tyre wheel rim or 15 ° of seat angles at 5 ° of seat angles.
For ease of understanding, below in conjunction with Fig. 1, to thering is the performance structure of the improved tire of bead structure in the present embodiment, be described:
In the utility model embodiment, having the improved tire of bead structure can manufacture by following method:
First on forming machine, make cylindrical shape assembly set; Then the enhancement Layer 1 of fitting on cylindrical shape assembly set; Then on enhancement Layer 1, paste again body piles 1035; Then on body piles 1035, paste again enhancement Layer 2 1032; Then the bead core being combined into by support glue 1034 and bead coil 1033 is buckled on body piles 1035; Then the shoulder wedge of fitting on body piles 1035; And then the bizet assembly posting is enclosed within to the centre of body piles on forming machine; Follow inflation, sizing, anti-package, pressing and make fetus, finally above-mentioned fetus being vulcanized and can obtain tire finished product.
Tire in use, sidewall 102 is owing to being subject to the combined action of crown 101 pressure and tire rim bearing force, can deflect laterally distortion, thereby concentrate at body piles 1035 anti-package end points and the larger strain and stress of the outer endpoint location generation of enhancement Layer 1, the tire of manufacturing by said method, by increase enhancement Layer 2 1032 in tire, on the one hand, can strengthen the bending stiffness at body piles 1035 anti-package end points and the outer end points of enhancement Layer 1 position, extenuate the rigidity gradient of above-mentioned two endpoint locations simultaneously.Total effect shows as the strain that reduces the endpoint location of body piles 1035 and the outsourcing endpoint location of enhancement Layer 1 and the stress concentration that reduces above-mentioned two endpoint locations, thereby significantly reduces the heat-dissipating of endpoint location rubber, on the other hand, when tire is subject to the combined action of crown pressure and tire rim bearing force, at tire bead position: power is when from body piles 1035 turn-up section end points and enhancement Layer 1, these two rubber segments more than end points of end points are transitioned into body piles 1035 turn-up sections and enhancement Layer one 1031 outsourcing section, ess-strain is concentrated in the endpoint location of body piles 1035 turn-up sections and enhancement Layer one 1031 outsourcing sections, cause tyre bead easily to damage, after increasing enhancement Layer 2 1032, steel cord reinforcing layer can transmit flexure stress, also the stress soon passing over from rubber segments has gently been transferred to body piles 1035 turn-up sections and enhancement Layer one 1031 outsourcing sections by enhancement Layer 2 1032, thereby be unlikely to make Stress-strain concentration in the position of the end points of body piles 1035 turn-up sections and enhancement Layer one 1031 outsourcing sections, no matter this design is fitted in drop-center rim or the tire of wedged bottom wheel rim can obtain good performance.

Enhancement Layer one 1031 outsourcing end points can be on the end points of body piles 1035, also can be under the end points of body piles, it is different with the stress concentration degree of the end points of body piles 1035 that the difference of above-mentioned two kinds of optional modes is that enhancement Layer 2 1032 is alleviated enhancement Layer one 1031 outsourcing end points.
Refer to Fig. 2, for enhancement Layer one 1031 outsourcing end points are on the end points of body piles 1035, and be fitted in the tire on inner tube of a tyre wheel rim that has at 5 ° of seat angles;
Refer to Fig. 3, for enhancement Layer one 1031 outsourcing end points are on the end points of body piles 1035, and be fitted in the tire on the tubeless rim at 15 ° of seat angles;
Refer to Fig. 4, for enhancement Layer one 1031 outsourcing end points are under the end points of body piles 1035, and be fitted in the tire on inner tube of a tyre wheel rim that has at 5 ° of seat angles;
Refer to Fig. 5, for enhancement Layer one 1031 outsourcing end points are under the end points of body piles 1035, and be fitted in the tire on the tubeless rim at 15 ° of seat angles.
Alternatively, the cross-sectional plane of bead coil 1033 is hexagon, quadrangle, circle or oval.
Alternatively, support glue 1034 by one or more rubber extrusion formings, when support glue 1034 is formed by multiple different rubber extruding, support the harder rubber for large end of glue 1034, support the softer rubber for small end of glue 1034.
Alternatively, enhancement Layer 1 and enhancement Layer 2 1032 are steel cordline.
Above-mentioned enhancement Layer 1 can be used the steel cord of 3+9 * 0.22+0.15 structure, and the density of arranging is 60 pieces/decimeter, cuts angle 30 degree, cuts width 90mm; Above-mentioned enhancement Layer 2 1032 can be used the steel cord of 3 * 0.2+6 * 0.35 structure, and the density of arranging is 40 pieces/decimeter, cuts angle 60 degree, cuts width 50mm.
