Abstract
The utility model discloses a giant all-steel engineering radial tyre with the side edge of a steel wire ring being stuck with transition type glue, comprising a tyre tread, a tyre body cord fabric, a belt layer and the steel wire ring with a polygonal section, wherein the tyre body cord fabric bypasses the steel wire ring to form a turnup tyre body cord fabric; a gap is left between the turnup tyre body cord fabric and the outer edge side of the steel wire ring; the gap is internally filled with the transition type glue which is fixedly connected with the outer edge side of the steel wire ring, thus preventing the air hidden in the position from forming tyre bead bubble of the finished tyre after vulcanization, avoiding that the stress of the tyre body cord fabric at the corner of the steel wire ring is centralized and leading the stress transition between the tyre body cord fabric and the steel wire ring to be uniform.
Description
Technical field
The utility model relates to a kind of engineering radial-type tyre, specifically, relates to the giant all-steel engineering radial tire that a kind of bead coil side posts transition type glue.
Background technology
At present, giant all-steel engineering radial tire is in the starting stage in China, a lot of aspects, comprise structure design, compound design, device fabrication etc. all in test, grope.General bead coil structure is hexagon or polygon, has outstanding corner angle on polygonal bead coil, and there are the gap in carcass cord and the bead coil internal diameter dual-side of walking around bead coil internal diameter anti-package thus, and tyre vulcanization post gap place easily forms the tyre bead bubble; When tire used, because carcass cord distribution of stress inequality, edges and corners formed stress concentration, in the tire use between bead coil and the carcass cord easily delamination separate.
The utility model content
The utility model is the gap that exists with bead coil internal diameter dual-side after the solution carcass cord anti-package, provide good with the bead coil bond properties after a kind of carcass cord anti-package, the uniform a kind of bead coil side of carcass cord distribution of stress posts the giant all-steel engineering radial tire of transition type glue.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of bead coil side posts the giant all-steel engineering radial tire of transition type glue, comprise that tyre surface, carcass cord, bracing ply and cross section are polygonal bead coil, wherein the carcass cord is walked around bead coil and is formed anti-package carcass cord, has the gap between the outer avris of carcass cord and bead coil after the anti-package, it is characterized in that: be filled with transition type glue in the described gap, the outer avris of described transition type glue and bead coil is affixed.
Below be the utility model for further improvement of these options:
Transition type glue adopts with carcass cord ply compound and bead coil and extrudes all good sizing material of glue bond performance.The cross sectional shape of described bead coil is a hexagon, is semicircular arc according to the gap that forms between anti-package carcass cord and the bead coil, and the cross sectional shape of described transition type glue is an isosceles trapezoid, and the outer avris of its bottom and bead coil is affixed.Like this, transition type glue has been filled up the space of bead coil side and carcass cord, can reduce sulfuration back finished tire tyre bead bubble, improve the product qualified rate after vulcanizing, can avoid carcass cord and bead coil corner angle stress concentration again, make between carcass cord and the bead coil transition of stress even, can also increase the binding power between carcass cord and the bead coil, delamination between bead coil and the carcass cord in the use of minimizing tire, the service life of improving tire.
The bottom width of described transition type glue is than the little 10～20mm of bead coil side width, and upper base hem width degree highly is 1.5～3mm than the little 5～10mm of bottom width.
The utility model adopts technique scheme, has the following advantages:
1, after the normal moulding of bead coil, sticks transition type glue, filled the space of bead coil side and carcass cord, prevent that this place from sheltering air and forming sulfuration finished tire tyre bead bubble afterwards in bead coil internal diameter dual-side center.
2, avoided the carcass cord at bead coil edges and corners stress concentration, made between carcass cord and the bead coil transition of stress even.
3, transition type glue adopts with carcass cord ply compound and bead coil and extrudes all good sizing material of glue bond performance, can increase the binding power between carcass cord and the bead coil.
4, production technology is simple, needn't increase new equipment input.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 posts the giant all-steel engineering radial tire sectional schematic diagram of transition type glue for bead coil side among the utility model embodiment;
Accompanying drawing 2 be among the utility model embodiment the transition type sticker at the structural representation of bead coil internal diameter dual-side;
Accompanying drawing 3 is the structural representation of transition type glue among the utility model embodiment.
Among the figure: 1-anti-package carcass cord; The 2-bead coil; 3-transition type glue; The 4-tyre surface; 5-carcass cord; The 6-bracing ply; A-bead coil side width; B-upper base hem width degree; C-bottom width.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of bead coil side posts the giant all-steel engineering radial tire of transition type glue, comprise that tyre surface 4, carcass cord 5, bracing ply 6 and cross section are hexagonal bead coil 2, wherein carcass cord 5 is walked around bead coil 2 and is formed anti-package carcass cord 1, have the gap between the outer avris of carcass cord 1 and bead coil 2 after the anti-package, be filled with transition type glue 3 in the described gap, described transition type glue 3 is affixed with the outer avris of bead coil 2.
As Fig. 2, shown in Figure 3, transition type glue 3 adopts with carcass cord ply compound and bead coil and extrudes all good sizing material of glue bond performance.According to the gap that forms between carcass cord 1 after the anti-package and the bead coil 2 is semicircular arc, and the cross sectional shape of described transition type glue 3 is an isosceles trapezoid, and the outer avris of its bottom and bead coil 2 is affixed.Like this, transition type glue 3 has been filled up the space of carcass cord 1 after bead coil 2 sides and the anti-package, can reduce sulfuration back finished tire tyre bead bubble, improve the product qualified rate after vulcanizing, can avoid carcass cord and bead coil corner angle stress concentration again, make between carcass cord and the bead coil transition of stress even, can also increase the binding power between carcass cord and the bead coil, delamination between bead coil and the carcass cord in the use of minimizing tire, the service life of improving tire.
The utility model production stage is as follows:
1, designs a kind of sizing compound formula.It is all good that this sizing material and carcass cord ply compound and bead coil are extruded the glue bond performance.
2, preparation transition type glue: design a shape of the mouth as one speaks model, use this shape of the mouth as one speaks model on extruder, to extrude transition type glue 3, this transition type glue 3 bottom width b are than the little 10～20mm of bead coil side width a, and upper base hem width degree c highly is 1.5～3mm than the little 5～10mm of bottom width b.
3, after bead coil 2 normal moulding, stick transition type glue 3 and compacting in bead coil 2 internal diameter dual-sides center.
4, other operation is normal, is about to carcass cord 5 and walks around bead coil 2 internal diameters formation anti-package carcass cord 1, and carcass cord 5 is filled by transition type glue 3 with bead coil 2 internal diameter dual-side gaps.
After the above step operation, proceed series of process such as moulding, sulfuration, prepare finished product.
