Abstract
The utility model relates to an all-steel tyre bead strengthening structure for an off-road radial ply tyre. The all-steel tyre bead strengthening structure for the off-road radial ply tyre comprises a bead ring (7) and compound fillers (2 and 6), wherein steel wire tyre cord fabric (5) is arranged outside the bead ring (7) and the compound fillers (2 and 6), tyre bead nylon wrappers (3A, 3B, 3C, 3D) are arranged outside the steel wire tyre cord fabric (5), the reversely wrapping end point of the steel wire tyre cord fabric (5) is higher than the external end points of the tyre bead nylon wrappers (3A, 3B, 3C, 3D), and a layer of tyre bead abrasion resistant compound (4) and a layer of sidewall rubber (1) are arranged outside the tyre bead nylon wrappers (3A, 3B, 3C, 3D). The all-steel tyre bead strengthening structure is characterized in that the tyre bead nylon wrappers (3A, 3B, 3C, 3D) is formed by interleaving at least two layers of nylon fabric, and the included angle between the nylon cord thread and the periphery is 30 to 90 degrees.
Description
Technical field
The utility model relates to tyre rim to be strengthened, and it can be applied to the cross-country radial-ply tyre of all types of all steels, but particularly is applicable to the adjustable inflation pressure tyre into cross-country broken country or desert pavement design.
Technical background
The position, rim of the mouth of the all-steel radial tyre of ordinary construction is by bead coil, steel wire carcass cord, compositions such as outside or U shaped steel silk rim of the mouth enhancement Layer and wear-resisting glue, the damage at position, rim of the mouth appears in the sub-port structure of this structure easily under tire heavy duty and low air pressure condition, this mainly is owing to following reason: the rigidity of carcass cord and steel wire infantees is big, when squeegee action is bigger, obvious at position, rim of the mouth carcass cord anti-package end points and heel fabric end points stress concentration, the strain of end points place is serious, when tire constantly rotates, this big strain makes this position produce huge heat, heat constantly gathers and causes finally that elastomeric material is aging to become fragile and causes the crackle generation, when crackle along with repeatedly and constantly the enlarging of strain up to the tire outside, will cause the rim of the mouth explosion of tire and the in-use performance of tire is completely lost.Above-mentioned strain is big more, and the service life of tire is just short more, and performance is poor more.
Increase position, the rim of the mouth life-span mainly relies on the intensity that improves tyre bead portion to realize at present, adopt U shaped steel silk infantees enhancement Layer as Chinese patent 00207683.7, Chinese patent 02234433.0 adds one deck nylon infantees enhancement Layer in the steel wire infantees outside, Chinese patent 200820149422.5 increases sealing rubber etc. in the enhancement Layer outer end, such scheme has certain effect to the intensity that solves the position, rim of the mouth, but infrabar problem for cross-country radial-ply tyre, not only need the rim of the mouth to have enough intensity, also must possess certain toughness, thereby reduce position, the rim of the mouth infantile failure of cross-country radial-ply tyre.
The utility model content
The purpose of this utility model is to overcome the above-mentioned shortcoming that exists in the prior art, position, the rim of the mouth additional strengthening of the cross-country radial-ply tyre of a kind of all steel is provided, this structure will make the tyre rim position when having enough intensity, have good toughness, this structure is adapted to cross-country radial-ply tyre, satisfies it and carry out the pressure regulation use under the situation of non-road surface.
The purpose of this utility model is achieved through the following technical solutions
Position, all steel of the present utility model cross-country radial-ply tyre rim of the mouth additional strengthening, comprise bead coil, compound tyre bead filling glue, outside bead coil and composite filled glue, be provided with steel wire carcass cord, carcass cord peripheral hardware has rim of the mouth nylon infantees, each layer nylon infantees is equal difference and distributes, and the wear-resisting glue in one deck rim of the mouth is arranged outside the nylon infantees of rim of the mouth.
Position, described all steel cross-country radial-ply tyre rim of the mouth additional strengthening, the integral thickness transition of nylon infantees present position, rim of the mouth is even, and thickest point differs 2～5mm with the thinnest dot thickness.
Wide wrong subsides and the mode of pasting of position, described rim of the mouth additional strengthening employing, adjacent each layer is intersection and distributes, and each layer cord angle and circumferential angle α are between 30 to 90 °.
Position, described rim of the mouth additional strengthening, rim of the mouth nylon infantees adopts the U type structure of wrapped wire circle, and its outer end highest point is lower than uppermost 10～50mm.
The beneficial effects of the utility model are as follows: rim of the mouth nylon bag cloth adopts adjacent two layers to be the intersection arrangement in (1) the utility model, forms the net structure at position, rim of the mouth, will guarantee the sufficient intensity at tyre rim position; (2) owing to adopt multilayer rim of the mouth nylon infantees, each interlayer equal difference distributes, and makes the thickness transition at position, rim of the mouth even, and the thickness difference of thickness and thinnest part is at 2～5mm, the transition of stress at position, rim of the mouth was more even when tire used, and reduced the stress concentration degree at position, rim of the mouth; (3) nylon infantees in rim of the mouth adopts the form of low inside and high outside U type wrapped wire circle, has effectively strengthened position, rim of the mouth in-to-in intensity, makes position, rim of the mouth intensity distributions even, the infantile failure at position, rim of the mouth when reducing the tire infrabar.
