Problems solved by technology
At present, some bias aviation tires have as many as 14 layers of carcass ply. However, the width of the joint surface of some rims is small. So many inner carcass plies are turned up with wire rings, which will inevitably cause the width of the tire bead to increase. Larger than the width of the rim landing surface, affecting the fit between the tire bead and the rim landing surface

Embodiment Construction
[0009] The present invention will be described in further detail below in conjunction with accompanying drawings and examples.
[0010] refer to figure 1 , a bias aviation tire that can effectively reduce the width of the bead, including the 1st to 4th layer of cord A, the 5th to 6th layer of cord B, the 7th to 8th layer of cord C, the 9th to 12th layer of cord D, the first 13-14 layers of cord E, inner traveler F, and outer traveler G. When the cords are attached, the 1st to 6th layers of cords (A and B) form 1# cord tubes, the 7th to 8th layers of cord C form 2# cord tubes, and the 9th to 14th layers of cords (D and E) form 3# Curtain barrel. Different from the existing technology, in the 1# cord tube, only the 1st to 4th layers of cord A turn up the traveler, while the 5th and 6th layer of cord B does not have a turn-up traveler, and the end of the cord B is about 20mm; 2# cord tube C is pasted on the turned-up 1# cord tube, and 2# cord tube C has no turned-up steel trav...

The invention discloses a diagonal aircraft tyre capable of effectively reducing the bead width. The diagonal aircraft tyre comprises 14 layers of cord fabric, inner-side steel wire rings and outer-side steel wire rings. The diagonal aircraft tyre is characterized in that only the first to the fourth layers of cord fabric are reversely packaged by the steel wire rings in a cord-fabric drum 1#, while the fifth and the sixth layers of cord fabric are not reversely packaged by the steel wire rings, and the distance between the end head of the cord fabric and the inner-side steel wire ring is about 20mm; a cord-fabric drum 2# is attached on the reversely packaged cord-fabric drum 1# and is not reversely packaged with the steel wire rings, and the distance between the end head and the inner-side steel wire ring is about 10mm; only the ninth to the twelfth layers of cord fabric are reversely packaged by the steel wire rings in a cord-fabric drum 3#, while the thirteenth and fourteenth layers of cord fabric are not reversely packaged by the steel wire rings, and the distance between the end head of the cord fabric and the inner-side steel wire ring is about 20mm. The diagonal aircraft tyre disclosed by the invention has the advantages that when the inflated pressure of the tyre is extremely high and the width of the jointing surface of a rim is smaller, the bead structure not only can provide enough strength for a tyre body, but also can reduce the bead width of the tyre obviously so as to form good matching on the jointing surface of the bead and the rim.
Description
technical field [0001] The invention belongs to the field of aviation tires, and in particular relates to a bias aviation tire which can effectively reduce the width of the bead. Background technique [0002] With the continuous development of the aviation industry, the inflation pressure of aviation tires continues to increase, and the inflation pressure of some tires is even as high as 2.4MPa. When the strength and density of the carcass cord remain unchanged, enough cord plies must be provided to ensure that the carcass strength of the tire meets the standard requirements. At present, some bias aviation tires have as many as 14 layers of carcass ply. However, the width of the bonding surface of some rims is small. So many inner carcass plies are turned up with wire rings, which will inevitably cause the width of the tire bead to increase. If it is larger than the width of the rim landing surface, it will affect the fit between the tire bead and the rim landing surface. ...
