Embodiment Construction

[0017] The radial aviation tire of the present invention comprises a belt layer, the belt layer is formed by laminating at least one belt layer group, the angle α between the belt layer cord 7 and the tread circumferential direction is 10°-20°, Preferably 12°~17°; wherein,

[0018] The belt layer group is formed by laminating three or four layers of belt ply layers 4. In the same group of belt layer groups, the two ends of the lowermost belt layer layer 4 are folded upward to form curling 6, and the curling 6 Wrap the two ends of the other belt plies 4 in the belt group except the first belt ply 4, and the ends of the curling 6 are connected with the two ends of the first belt ply 4 respectively. Contiguously, the interface 5 is located within the coverage of the belt ply 4 or the crown layer above the first belt ply 4 .

[0019] In two adjacent belt plies in the same belt group, the width of the upper belt ply 4 is narrower than that of the lower belt ply 4; in two adjacent ...

Abstract

The invention relates to a meridian aircraft tyre, in particular to a meridian aircraft tyre having a folding edge-belted layer structure. The meridian aircraft tyre comprises a belted layer formed bybonding at least one belted layer group. Curtain lines of the bundle layer and a tyre surface form an included angle of 10 DEG to 20 DEG in a circumferential direction, wherein the belted layer groupis formed by bonding three layers or four layers of belt curtain cloth layers. In the same group of belted layer group, both ends of the bottom belt curtain cloth layer are reversed upwards into turned edges; the turned edges cover both ends of other belt curtain cloth layers except the first belt curtain cloth layer in the belted layer group; the ends of the turned edges are respectively connected with both ends of the first belt curtain cloth layer; and connection positions are within the range of the belt curtain cloth layer or a tyre top layer above the first belt curtain cloth layer. Byadopting the meridian aircraft tyre with the belted layer structure, the bundle layer has good stability and can effectively avoid producing a peeled meridian aircraft tyre between the ends of the curtain lines and glue.

Description

technical field [0001] The present invention relates to a radial aircraft tire, in particular to a radial aircraft tire with a folded and edged belt layer structure. Background technique [0002] Radial aviation tires are used under high internal pressure, high speed and heavy load. The belt layer structure of existing radial aviation tires is equipped with multi-layer plies to ensure the strength and centrifugal force of the tire and meet the requirements of radial aviation tires. Conditions of Use. Once the number of plies is too large, when they are fitted together, since there is a free truncated end at the end of the belt cord, and the end of the belt cord is a cut-off opening, the stress concentration at the truncated end , under the action of high speed, it is easy to peel off between the end of the cord and the rubber, resulting in damage to the end of the tire belt. Contents of the invention [0003] The technical problem to be solved by the present invention is...
