Abstract
The utility model relates to a tyre bead, in particular to a tubeless meridian improved tyre bead. The tubeless meridian improved tyre bead consists of a sidewall rubber, an upper triangular rubber, a bead fabric, a bead abrasion-resistant rubber, a steel wire ring, a lower triangular rubber, a nylon wrapping fabric, a lining layer and a tyre body. The tubeless meridian improved tyre bead can solve the problem of early damage of the tyre bead part; specifically, two layers of nylon wrapping fabrics with angles are attached to the inner turn-up end point of the bead protective fabric, play a main role in improving the strength and the rigidity of the bead part, meanwhile, play a role in protecting the inner turn-up end point, reduce internal cracks of the bead, inhibit over-high deformation of the bead part during running, finally reduce the quality defects of hollowing, cracking, spinning explosion and the like of the bead, prolong the service life of the tyre and increase the renovation frequency of the tyre; and after test contrast, the tubeless meridian improved tyre bead shows that the circumferential cracking rate of the bead in the use of the tyre is 1 percent before improvement and declines to 0.2 percent after the patent is applied.
Description
Technical field
The utility model relates to a kind of tire bead, and especially a kind of inner tube free radial improves tire bead.
Background technology
Tubeless tires has advantages such as energy-saving and environmental protection, manufacturing expense are low, has brought into use at home at present, replaces tube-tyre.At present, domestic autotruck radial-ply tyre, just all steel tire of saying usually, the in use large percentage of infantile failure.In early days in the middle of the defective of Sun Huaiing, it is maximum a kind of defectives that circumferential breach appears in wheel tyre bead mouth, and circumferentially the position of breach is just at the anti-package end points place of all steel tire carcass cord.This defective is that each manufacturer of domestic all steel tire has, and is mainly caused by automobile overload.
Domestic each producer is all in the phenomenon of being devoted to solve the circumferential breach of wheel tyre bead mouth, and automobile overload causes the squeegee action zone to be displaced downwardly to circle oral area position.At carcass cord anti-package end points, the terminal and pliable and tough rubber junction of hard steel wire is out of shape excessive, and Sheng Regao splits thereby make steel wire and rubber junction physical property descend.Each producer solves the scheme of this defective nothing more than being out of shape from inhibition and falling low-heat-generation two aspects and set about.Yet, solution is not preferably arranged up till now yet.
The utility model content
Technical problem to be solved in the utility model provides a kind of inner tube free radial that solves the circumferential breach problem of wheel tyre bead mouth and improves tire bead.
For solving the problems of the technologies described above, the utility model is realized as follows: inner tube free radial described in the utility model improves tire bead and is made up of sidewall rubber, last triangle glue, heel fabric, the wear-resisting glue in rim of the mouth, bead coil, following triangle glue, nylon infantees, inside liner and carcass; Sidewall glue-line upper part and body piles are bonding, following partly respectively with the wear-resisting glue-line bonding connection of last triangle glue-line and rim of the mouth; The wear-resisting glue-line outside, rim of the mouth is bonded with the heel fabric layer; The also sticking nylon bag layer of cloth that is fitted with of heel fabric layer one side; Nylon bag layer of cloth inboard also is bonded with inside liner; Body piles is bonded in heel fabric layer inboard; The body piles inside bottom fixedly is bonded with bead coil; The bead coil top is bonded with down the triangle glue-line, and following triangle glue-line constitutes bonding connection with last triangle glue-line simultaneously.
Described nylon bag layer of cloth is two-layer nylon infantees.
Good effect of the present utility model: inner tube free radial described in the utility model improves tire bead can solve the getting up early damage of tyre rim position; existing design is improved; adopt and suppress the terminal way of being out of shape of steel wire with the rubber junction; specifically; the anti-package end points place nylon infantees of two-layer band angle of fitting in cloth is protected in the rim of the mouth; it mainly acts on is intensity and the rigidity that improves the position, rim of the mouth; play the effect of anti-package end points in the protection simultaneously; reduce the rim of the mouth implosion; distortion is excessive in travelling in inhibition position, rim of the mouth; the final bead separation that reduces; split and the mass defect such as quick-fried of reeling off raw silk from cocoons, prolong the service life of tire, increased the number of times of tyre rebuilding; show in test contrast back; before not improving, it is 1% that tire uses the circumferential breach rate of centre circle mouth, drops to 0.2% after using this patent.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is described in further details below in conjunction with the specific embodiment and accompanying drawing.At this, exemplary embodiment of the present utility model and explanation thereof are used to explain the utility model, but not as to qualification of the present utility model.
As shown in Figure 1, inner tube free radial improvement tire bead described in the utility model is made up of sidewall rubber 1, last triangle glue 2, heel fabric 3, the wear-resisting glue 4 in rim of the mouth, bead coil 5, following triangle glue 6, nylon infantees 7, inside liner 8 and carcass 9; 1 layer of upper part of sidewall rubber and 9 layers of carcasses are bonding, following partly respectively with 2 layers in last triangle glue and 4 layers of bonding connection of the wear-resisting glue in rim of the mouth; 4 layers of outside of wear-resisting glue, rim of the mouth are bonded with 3 layers of heel fabrics; Also sticking 7 layers of the nylon infantees that are fitted with of 3 layer of one side of heel fabric; 7 layers of inboard of nylon infantees also are bonded with inside liner 8; Carcass is bonded in 3 layers of inboard of heel fabric for 9 layers; 9 layers of inside bottom of carcass fixedly are bonded with bead coil 5; Bead coil 5 tops are bonded with down 6 layers in triangle glue, and 6 layers of while of following triangle glue constitute bonding connection for 2 layers with last triangle glue.
Described nylon infantees is two-layer nylon infantees 7 for 7 layers.
