Abstract
The invention relates to a tire, in particular to a tire bead structure which sequentially comprises an air impervious layer, a transition layer, a steel wire seam allowance layer and a tire body layer from inside to outside. The steel wire seam allowance layer comprises a zero-angle steel wire seam allowance layer, a steel wire tire cord is arranged in the zero-angle steel wire seam allowance layer, covering rubber is arranged between two adjacent steel wires in the steel wire tire cord, each steel wire in the steel wire tire cord forms a complete circle, and any two circles are parallel to each other. The tire bead structure has higher strength, so that deformation of a tire bead part is small, and the bead problem is prevented from appearing better.
Description
Technical field
The present invention relates to a kind of tire, specifically a kind of tire bead structure.
Background technology
Present vehicle is being undertaken many missions, the normal mark of some vehicle carries, not high to the tire load bearing requirements, also have some vehicles to require to be applicable to travelling (to comprise the non-road surface of mating formation) on all kinds of different road surfaces, to load-carrying properties, require high, so the tyre bead portion of this class vehicle must be enough strong, in order to support higher carrying.Tyre bead: refer to that tire is arranged on the part contacted with wheel rim on wheel rim.This part is one of tire moderate finite deformation point, for requiring the outstanding vehicle of load-carrying capacity, increase tyre bead intensity essential, and reinforced bead intensity can be undertaken by two aspects: the one, purchase high-intensity steel wire cord tire line, shortcoming is somewhat expensive, in the situation that now tyre industry is competed more and more fiercely, virtually increased the cost of tire enterprise; The 2nd, adopt suitable steel wire heel fabric, this method is simple, when not increasing enterprise cost, can well guarantee the intensity of tyre bead portion.
Steel wire infantees in each tire enterprise is generally to adopt the calendering of steel wire strand cord to make at present, then on the low-angle cutting machine, is cut into an angle between 20～40, finally is fitted in the tire bead relevant position.Such structure is owing to there being angle to exist, and the banding coefficient reduces, so running into the large deformation that can not well suppress tyre bead portion under severe service condition, causes such as quick-fried some problems such as grade in rim of the mouth.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of tire bead structure is provided, adopt this bead structure can make the tire bead position obtain better stirrup effect, there is higher intensity, make the distortion of tire bead position little, better prevent the generation of tyre bead problem.
According to technical scheme of the present invention: a kind of tire bead structure, it has air-retaining liner, cambic horizon, steel wire rim of the mouth layer, body piles from inside to outside successively, it is characterized in that: described steel wire rim of the mouth layer comprises zero degree steel wire rim of the mouth layer, layer inside, zero degree steel wire rim of the mouth is provided with steel cord, be provided with and cover glue between adjacent two steel wires in steel cord, in described steel cord, every steel wire all forms complete circle, and is parallel to each other between any two circles.
As a further improvement on the present invention, described steel wire rim of the mouth layer also comprises low-angle steel wire rim of the mouth layer, and low-angle steel wire rim of the mouth laminating closes and is arranged between body piles and zero degree steel wire rim of the mouth layer, and the some layers of bead coil that low-angle steel wire rim of the mouth layer includes are in the overlapping laying of angle.
Technique effect of the present invention is: the present invention is simple and reasonable for structure, and reinforced bead preferably adopts the tire of bead structure of the present invention, its load-carrying capacity, and tyre bead intensity outstanding, effectively prevent the problems such as rim of the mouth implosion, rim of the mouth be quick-fried; First scheme of the present invention, reduced the use amount of steel wire parts, and under the condition of similar performance, zero degree steel wire rim of the mouth width greatly reduces than low-angle steel wire rim of the mouth, cost-saving, cover tire weight saving; The present invention is easy to realize, without changing existing frock, just can be produced.
The accompanying drawing explanation
Fig. 1 is the first embodiment structural representation of the present invention.
Fig. 2 is the second embodiment structural representation of the present invention.
The schematic cross-section that Fig. 3 is zero degree steel wire rim of the mouth layer.
The structural representation that Fig. 4 is zero degree steel wire rim of the mouth layer.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 4, comprise body piles 1, steel wire rim of the mouth layer 2, low-angle steel wire rim of the mouth layer 21, zero degree steel wire rim of the mouth layer 22, steel cord 221, cover glue 222, cambic horizon 3, air-retaining liner 4 etc.
As shown in Figure 1, the present invention is a kind of tire bead structure, it has air-retaining liner 4, cambic horizon 3, steel wire rim of the mouth layer 2, body piles 1 from inside to outside successively, described steel wire rim of the mouth layer 3 comprises zero degree steel wire rim of the mouth layer 22, layer 22 inside, zero degree steel wire rim of the mouth are provided with steel cord 221, be provided with and cover glue 222 between adjacent two steel wires in steel cord 221, in described steel cord 221, every steel wire all forms complete circle, and is parallel to each other between any two circles.The said structure content is the first embodiment of the present invention.
Fig. 2 shows the second embodiment of the present invention, with the difference of the first embodiment, only be, described steel wire rim of the mouth layer 3 also comprises low-angle steel wire rim of the mouth layer 21, and layer 21 laminating in low-angle steel wire rim of the mouth are arranged between body piles 1 and zero degree steel wire rim of the mouth layer 22, and the some layers of bead coil that low-angle steel wire rim of the mouth layer 21 includes are in the overlapping laying of angle.
The structural representation that Fig. 3, Fig. 4 are zero degree steel wire rim of the mouth layer 22, the zero degree steel wire rim of the mouth layer 22 in the present invention adopts steel wire strand cord 221 to make coated with the high strength sizing material; During fabrication, at first zero degree steel wire rim of the mouth layer 22 is carried out the calendering processing of corresponding required width, then normally batch.
The present invention is through the indoor lathe experiment of tire and outdoor road examination, determine and adopt the tire of this structure to there is good load-carrying capacity, even in the situation that overload also can extend the service life of tire well, prevent the generation of all kinds of rims of the mouth problem, the present invention manufactures simply, be easy to realize, be applicable to all full-steel radial ply heavy type tires.
