Abstract

The invention discloses a meridian aircraft tire capable of reducing interface shear stress and improving bead durability. The tire is characterized in that one layer of transition glue is arranged at a bead part and positioned on the outer side of a carcass ply, is 2-4 mm in thickness, and is 60-70 degrees in shore hardness; two layers of buffer fiber cord ply are arranged outside the transition glue; the density of cord threads is 35-90 piece/100 mm; the included angles between the cord threads and the peripheral direction are 20-90 degrees; and warps of the two layers of fly are across arranged corresponding to the radial direction. The improved meridian aircraft tire can reduce interface stress, strain and themogenesis between the carcass at the bead part and the rubbers at the outer side, and can improve the bead durability by more than 80% under the rigorous conditions; and the dynamic performance of the tire can meet the requirements of airworthiness standard (GJB683A).

Description

Technical field [0001] The present invention involves aviation tires, especially the sub -meridial aviation tires that can reduce interface shear stress and improve durability under the durability of tires. Background technique [0002] Under the strict dynamic conditions of the meridial aviation tires, due to the low stiffness of the tire side, the tire ring part is large, and it is easy to cause the fetal body curtain or tire ring to enhance the layer of the outer rubber.The fatigue and safety performance of the tire cannot meet the requirements of the airworthiness standard.At present, the method of reducing the strain, stress and heat of the fetal ring parts include: (1) adjust the height of the carcass reflux; (2) to set the tire ring enhancement layer; (3)Set high elasticity, low -growing hot rubber.These methods have a good improvement of fatigue resistance of aviation tire circles, but they still cannot meet the requirements of airworthiness standards under the requiremen...
