Description
Technical field
The utility model relates to a kind of tire, especially the special superelevation safety performance of dumping car and long life tire.
Background technology
At present, more for the tyre kind of dumping car in industry, especially for the tire of dumping car short distance height load-carrying type, there is following problem in it: because load-carrying is higher, inside the tyre bead of tire, loss is higher, and easily extend to tyre bead outside when the high loss in inner side, service life is limited.
Utility model content
The technical problems to be solved in the utility model is to provide the special superelevation safety performance of a kind of dumping car and long life tire, by realizing improving the ability suppressing squeegee action to the improvement of bead structure formal distribution, extend the time that inside tires damages backward outer extension simultaneously, improve the load-carrying safety of tire.
The utility model is achieved through the following technical solutions.
A kind of special superelevation safety performance of dumping car and long life tire, comprise the bead coil be all arranged in tyre bead, carcass plies, steel wire infantees strengthening course, above-mentioned bead coil is arranged on inside, above-mentioned tyre bead two ends and has insulation rubber coated, be provided with hard packing, above-mentioned hard packing and above-mentioned insulation rubber coated by above-mentioned carcass plies, and what carcass plies was positioned at inner side is continuous segment, what be positioned at outside is extension, above-mentioned extension arranged outside has antifriction rubber, above-mentioned steel wire infantees strengthening course is coated with outside above-mentioned carcass plies and outside above-mentioned antifriction rubber, steel wire infantees strengthening course arranged outside has the first nylon cloth strengthening course being shorter in length than above-mentioned steel wire infantees strengthening course, above-mentioned first nylon cloth strengthening course arranged outside has the second nylon cloth strengthening course being shorter in length than above-mentioned first nylon cloth strengthening course.
Further, the arranged outside of above-mentioned carcass plies has the 3rd nylon cloth strengthening course, above-mentioned 3rd nylon cloth strengthening course extends to outside above-mentioned steel wire infantees strengthening course, 3rd nylon cloth strengthening course arranged outside has the 4th nylon cloth strengthening course, and above-mentioned 4th nylon cloth strengthening course extends to the outside of above-mentioned steel wire infantees strengthening course.
Further, soft bead apex is provided with between the extension of above-mentioned carcass plies and above-mentioned hard packing.
Further, above-mentioned steel wire infantees strengthening course is coated with the 5th nylon cloth strengthening course near the port of tyre bead outside face and one section.
The beneficial effects of the utility model:
The ability that tire suppresses carcass ply end points to be out of shape under heavily loaded usage condition can be improved, extend and produce the time of outside breach because carcass end points continuous modification expands laterally, the probability of the body cord fracture caused because of phase mutual friction between bead coil with carcass can be reduced simultaneously, improve safety and the service life of tire.
Accompanying drawing explanation
Fig. 1 is the structural representation of the special superelevation safety performance of the utility model dumping car and long life tire.
Detailed description of the invention
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural representation of the special superelevation safety performance of the utility model dumping car and long life tire, with reference to Fig. 1, the utility model, the special superelevation safety performance of dumping car and long life tire, comprise the bead coil 4 be all arranged in tyre bead, carcass plies 1, steel wire infantees strengthening course 2, it is inner and have insulation rubber 5 coated that bead coil 4 is arranged on tyre bead two ends, is provided with hard packing 6, hard packing 6 and insulation rubber 5 coated by carcass plies 1.Insulation rubber 5 can avoid carcass under high-load condition because producing large deformation, thus makes body piles and the mutual friction of bead coil generation phase, and the risk that rubs of casingply the most at last.
And what carcass plies 1 was positioned at inner side is continuous segment 11, what be positioned at outside is extension 12, extension 12 arranged outside has antifriction rubber 8, ensure that the natural transition between two kinds of rigid material, also can reduce because of the application force that shear action produces between body piles and steel wire infantees, reduce the risk of fail in shear.
Be coated with steel wire infantees strengthening course 2 outside carcass plies 1 and outside antifriction rubber 8, the distortion of body piles end points under strained condition can be suppressed by actv., reduce carcass end points and produce the probability of breach because of distortion or extend the time producing breach.
Steel wire infantees strengthening course 2 arranged outside has the first nylon cloth strengthening course 32, first nylon cloth strengthening course 32 arranged outside being shorter in length than steel wire infantees strengthening course 2 to have the second nylon cloth strengthening course 33 being shorter in length than the first nylon cloth strengthening course 32.Further can retrain the distortion of body piles, the arrangement and the upside termination height of the first nylon cloth strengthening course 32, second nylon cloth strengthening course 33 tapers off, also become step wise reduction to arrange with close steel wire infantees, casingply end points, actv. disperses the distribution of stress of each end points.
In the implementation case, the arranged outside of carcass plies 1 has the 3rd nylon cloth strengthening course 34,3rd nylon cloth strengthening course 34 extends to outside steel wire infantees strengthening course 2,3rd nylon cloth strengthening course 34 arranged outside has the 4th nylon cloth strengthening course 35, and the 4th nylon cloth strengthening course 35 extends to the outside of steel wire infantees strengthening course 2.
Soft bead apex 7 is provided with between the extension 12 of carcass plies 1 and hard packing 6.
Steel wire infantees strengthening course 2 is coated with the 5th nylon cloth strengthening course 31 near the port of tyre bead outside face and one section.
5th nylon cloth strengthening course 31, the 3rd nylon cloth strengthening course 34, the 4th nylon cloth strengthening course 35, reduce steel wire infantees and improve because of end points, produce the probability of breach closer to deforming zone.
The utility model, the special superelevation safety performance of dumping car and long life tire, the ability that tire suppresses carcass ply end points to be out of shape under heavily loaded usage condition can be improved, extend and produce the time of outside breach because carcass end points continuous modification expands laterally, the probability of the body cord fracture caused because of phase mutual friction between bead coil with carcass can be reduced simultaneously, improve safety and the service life of tire.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow the personage being familiar with this art can understand the utility model content and be implemented, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
