Abstract
The invention relates to transitional filling type molding rubber. The transitional filling type molding rubber is characterized by comprising an intermediate type colloid and end type colloids integrally connected at two ends of the intermediate type colloid, wherein the intermediate type colloid is in clearance fit with the bottom surface, and the end type colloids are in clearance fit with the side edges. The transitional filling type molding rubber provided by the invention is filled into a clearance between a steel wire ring and a tire body, and the clearance can be sufficiently and fully filled with the molding rubber material, without using the rubber material at other parts of a tire for filling the clearance, so that the binding degree of the tire body and the steel wire ring is improved greatly, the tire bead strength of the tire is well enhanced, and the bearing capacity of the tire is improved.
Description
Technical field
The present invention relates to a kind of novel for the transition type filled-type type glue between tire carcass and bead coil, it is suitable for all all-steel radial tyres, belongs to tire production manufacturing technology field.
Background technology
The bead coil produced in current tire enterprise has two kinds of structures: the first is the bead coil that traditional nylon cloth is wound around parcel, and nylon cloth is first cut into one fixed width by it, then uses existing nylon Wiring apparatus to carry out the winding parcel of circumference to bead coil; The second does not use nylon cloth to wrap up, but on bead coil, use adhesive tape to carry out wrapping up (because adhesive tape shape is fixed, cannot use type glue, therefore perfectly cannot carry out sizing material to position, bead coil gap and supplement).For the tire adopting these two kinds parcel pattern bead coils, all there is following problems: carcass exists gap (as shown in Figure 1) upon bending with bead coil cohesive process all the time, wherein form gap, bottom surface between the top curved section of carcass and bead coil, between the side camber section of carcass and bead coil, form side play; And such gap needs the flowing of the sizing material at other positions to fill up, more or less will there is the problem of starved in other positions.
Along with the intensified competition of domestic tyre industry, especially the load-carrying demand of domestic automobile is more and more higher, in the face of this situation, the tire of the bead coil of these two kinds of structures existing is used to be difficult to meet the demands in load-carrying properties, all kinds of problem of easy generation, the fracture of wire of typical problem as tire be quick-fried, cut the symptom such as rim of the mouth, these symptom cause tire close towards early stage problem, have a strong impact on intensity and the service life of tire, the problem of blowing out that we are least ready to see even can be produced, threat to life safety time serious.
As everyone knows, the intensity of tire bead depends on two broad aspect: the intensity (this can solve by using the steel cord of more high strength) of first carcass; It two is mate anchoring strength between bead coil with carcass, and carcass and bead coil exist gap will have a negative impact to mating anchoring strength.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of transition type filled-type type glue is provided, it fills out in the gap that is located between bead coil and tire carcass, type glue sizing material fully can fill up gap, do not need to use other position sizing materials of tire to fill up gap, such tire carcass and bead coil conjugation strengthen greatly, better improve the tyre bead intensity of tire, improve tire capacity.
According to technical scheme provided by the invention: transition type filled-type type glue, it is characterized in that: comprise transition type colloid and be integrally connected to the end-type colloid at transition type colloid two ends, described transition type colloid and bottom surface clearance fit, described end-type colloid and side clearance fit.
As a further improvement on the present invention, the thickness of described transition type colloid is greater than the thickness of end-type colloid.
As a further improvement on the present invention, the connecting portion of transition type colloid and end-type colloid is provided with groove.
As a further improvement on the present invention, described groove is the trapezoidal groove of wide narrow base suitable for reading.
As a further improvement on the present invention, the end at the described end-type colloid back side is provided with slope.
compared with prior art, tool has the following advantages in the present invention:
(1), transition type filled-type type glue of the present invention is arranged between bead coil and carcass, can combine closely bead coil and carcass, changes the not enough and tyre bead portion problem of tire local sizing material that original structure (there is gap between bead coil and carcass) causes.
(2), by arranging transition type filled-type type glue; extra sizing material is added between carcass and bead coil; therefore the shearing stress coming from carcass parts can be cushioned better; better tyre bead is protected when overloading serious; prevent tire from occurring the quick-fried problem of fracture of wire, improve Using Life of Tyre.

Fig. 2 is the structural representation of embodiment of the present invention transition type filled-type type glue.
Fig. 3 is for applying tire bead position of the present invention sectional schematic diagram.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ Fig. 3, transition type filled-type type glue 5 in embodiment mainly comprises transition type colloid 5a and is integrally connected to the end-type colloid 5b at transition type colloid 5a two ends, transition type colloid 5a and gap, bottom surface 3 adaptation, end-type colloid 5b and side gap 4 adaptation.
As shown in Fig. 1 ~ Fig. 3, because the crooked radian of the top curved section of carcass 1 is larger than the crooked radian of side camber section, so the gap, bottom surface 3 formed between top curved section and bead coil 2 also than side camber section and the side gap 4 that formed between bead coil 2 large, correspondingly, the thickness of the transition type colloid 5a on transition type filled-type type glue 5 is also greater than the thickness of end-type colloid 5b.
As shown in Fig. 1 ~ Fig. 3, the cross-sectional plane due to bead coil 2 is hexagon, there is gap hardly between the seamed edge position of bead coil 2 and carcass 1.And the seamed edge position of bead coil 2 is just in time corresponding with the connecting portion of end-type colloid 5b with transition type colloid 5a, so the present invention is provided with groove 5c at the connecting portion place of transition type colloid 5a and end-type colloid 5b, and described groove 5c is preferably set to the trapezoidal groove 5c of wide narrow base suitable for reading, the sizing material degree of saturation specific humidity of tire tyre bead portion can be promoted so further, promote tyre bead intensity better.In addition, the end at the described end-type colloid 5b back side is provided with slope, is also to make transition type filled-type type glue 5 and tire and bead coil 2 with more adaptive laminating.
During embody rule, first on extruder, extrude transition type filled-type type glue 5 of the present invention, then forming operation is entered, after profiled part laminating drum posts carcass 1, transition type filled-type type glue 5 is located the appropriate location be fitted on carcass 1, next just normally carry out tire production operation in the past.The manufacturing of the present invention directly can adopt the existing installation of tyre production enterprise, without the need to increasing new installation.
Transition type filled-type type glue 5 of the present invention is arranged between bead coil 2 and carcass 1, and the size of transition type filled-type type glue 5 can adjust to guarantee adaptation according to bead coil 2 structure.The sizing material of the use of transition type filled-type type glue 5 of the present invention is through adjustment formula, and between bead coil 2 and carcass 1, conjugation is outstanding.Through the examination inspection of outside road, Using Life of Tyre of the present invention is adopted greatly to extend.And the present invention is applicable to all full-steel radial ply heavy type tires, can not increase the tire production time, be applicable to utilization and extention.
