Abstract
The present invention relates to transition type filled-type type glue, it is characterised in that: include middle type colloid and be integrally attached to the end-type colloid at middle type colloid two ends, described middle type colloid and bottom surface clearance fit, described end-type colloid and side clearance fit.The present invention fills out in the gap being located between wire loop and carcass, type glue sizing material can adequately fill up gap, need not use other position sizing materials of tire to fill up gap, so carcass is greatly enhanced with wire loop conjugation, preferably improve the tyre bead intensity of tire, improve tire capacity.
Description
Technical field
The present invention relates to a kind of novel for the transition type filled-type type glue between carcass and wire loop, it is suitable for all all-steel radial tyres, belongs to tire production manufacturing technology field.
Background technology
The wire loop produced in tire enterprise at present has two kinds of structures: the first is the wire loop 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 that wire loop carries out the winding parcel of circumference；The second is not use nylon cloth to wrap up, but uses adhesive tape to carry out wrapping up (owing to adhesive tape shape is fixed, it is impossible to use type glue, therefore position, wire loop gap perfectly cannot carry out sizing material and supplement) on wire loop.For using the tire of both parcel pattern wire loops, all there is following problems: carcass exists gap (as shown in Figure 1) all the time with wire loop cohesive process upon bending, wherein form gap, bottom surface between top curved section and the wire loop of carcass, between side camber section and the wire loop of carcass, form side clearance；And the sizing material flowing that such gap needs other positions is filled up, the problem that other positions will more or less exist starved.
Intensified competition along with domestic tyre industry, the especially load-carrying demand of domestic automobile is more and more higher, in the face of this situation, the tire using the wire loop of existing both structures is difficult to meet requirement in load-carrying properties, easily produce all kinds of problems, the fracture of wire of typical problem such as tire is 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, threat to life safety even can be produced time serious.
It is known that the intensity of tire bead depends on two broad aspect: the intensity (this can solve by using the all-steel cord of higher intensity) of first carcass；It two is the bond strength of mating between wire loop with carcass, and carcass exists gap and will have a negative impact to mating bond strength with wire loop.
Summary of the invention
It is an object of the invention 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 being located between wire loop and carcass, type glue sizing material can adequately fill up gap, need not use other position sizing materials of tire to fill up gap, so carcass is greatly enhanced with wire loop conjugation, preferably improves the tyre bead intensity of tire, improves tire capacity.
The technical scheme provided according to the present invention: transition type filled-type type glue, it is characterized in that: include middle type colloid and be integrally attached to the end-type colloid at middle type colloid two ends, described middle 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 middle type colloid is more than the thickness of end-type colloid.
As a further improvement on the present invention, middle type colloid is provided with groove with the connecting portion of end-type colloid.
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.
The present invention compared with prior art, has the advantage that
(1), the transition type filled-type type glue of the present invention is arranged between wire loop and carcass, it is possible to combine closely wire loop and carcass, changes tire local sizing material deficiency and tyre bead portion problem that original structure (there is gap between wire loop and carcass) is caused.
(2), by arranging transition type filled-type type glue; extra sizing material is added between carcass and wire loop; therefore the shear stress coming from carcass parts can preferably be buffered; tyre bead is preferably protected in the case of overload is serious; prevent tire from the quick-fried problem of fracture of wire occurring, improve Life of Tyre.

Fig. 2 is the structural representation of embodiment of the present invention transition type filled-type type glue.
Fig. 3 is the tire bead position sectional schematic diagram applying the present invention.
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, the transition type filled-type type glue 5 in embodiment mainly includes middle type colloid 5a and is integrally attached to the end-type colloid 5b at middle type colloid 5a two ends, middle type colloid 5a and gap, bottom surface 3 adaptation, and end-type colloid 5b is adaptive with side gap 4.
As shown in Fig. 1 ~ Fig. 3, owing to the crooked radian of the top curved section of carcass 1 is bigger than the crooked radian of side camber section, so between top curved section and wire loop 2 formed gap, bottom surface 3 also than side camber section and between wire loop 2 formed side gap 4 big, correspondingly, the thickness of the middle 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, owing to the cross section of wire loop 2 is hexagon, between seamed edge position and the carcass 1 of wire loop 2, there's almost no gap.And the seamed edge position of wire loop 2 is just corresponding with the connecting portion of end-type colloid 5b with middle type colloid 5a, so the present invention is provided with groove 5c at the connecting portion of middle type colloid 5a and end-type colloid 5b, and described groove 5c is preferably arranged to the trapezoidal groove 5c of wide narrow base suitable for reading, so can promote the sizing material saturation of tire tyre bead portion further, preferably promote tyre bead intensity.It addition, the end at the described end-type colloid 5b back side is provided with slope, also for making transition type filled-type type glue 5 and tire and wire loop 2 with more adaptive laminating.
When specifically applying, first on extruder, extrude the transition type filled-type type glue 5 of the present invention, subsequently enter forming operation, after profiled part laminating drum posts carcass 1, transition type filled-type type glue 5 location is fitted in the appropriate location on carcass 1, is the most just normally carried out conventional tire production operation.The manufacturing of the present invention can directly use the existing equipment of tyre production enterprise, it is not necessary to increases new equipment.
The transition type filled-type type glue 5 of the present invention is arranged between wire loop 2 and carcass 1, and the size of transition type filled-type type glue 5 can be adjusted to ensure that adaptation according to wire loop 2 structure.The sizing material of the use of transition type filled-type type glue 5 of the present invention is adjusted formula, and between wire loop 2 and carcass 1, conjugation is outstanding.Through the examination inspection of outside road, the Life of Tyre of the present invention is used to be greatly prolonged.And the present invention is applicable to all of full-steel radial ply heavy type tire, will not increase the tire production time, it is suitable for utilization and extention.
