Problems solved by technology
These methods have a certain effect on improving the speed performance of aviation tires, but for some small-sized civil aviation tires, these usual methods of improving speed performance still cannot meet the requirements of speed performance under high loads.
During the dynamic simulation test, the tires are prone to tread block or tread throwing problems

Embodiment Construction
[0012] The present invention will be further described below in conjunction with drawings and embodiments.
[0013] A belted bias aviation tire, comprising pattern groove 1, tread 2, tread belt reinforcing layer 3, reinforcing glue 4, carcass reinforcing layer 5, carcass ply 6, airtight layer 7, Steel traveler 8, steel traveler cloth 9, triangular rubber strip 10. Under the tire tread, there is a tread belt reinforcement layer 3 composed of a layer of nylon cord, which is formed by winding nylon rubber cords with a width of 10-25 mm along the angle of 4° with the tire circumferential direction. ; Under the reinforcing glue 4, there is a carcass reinforcing layer 5 composed of 2-4 layers of nylon cord, which has an angle of 30° with the tire circumferential direction; the carcass cord 6 is composed of 4 layers of nylon cord, and The included angle of the tire circumferential direction is 70°; the traveler cloth 9 is composed of one layer of nylon cord, and the included angle w...

The invention provides a bias belted aircraft tire. At least one wide-angle tread belt reinforcement layer is arranged at the lower part of a tread, and is used for hooping the body of the bias belted aircraft tire; the tread belt reinforcement layer is formed by winding of a nylon rubberized cord with the width of 10-25 mm at an included angle of 2-6 degrees formed with the circumference; the tread belt reinforcement layer cannot reach a tire shoulder in width and covers a whole crown. According to the bias belted aircraft tire, through reasonable selection about the angles between a tire body and reinforcement layers, stress of the tire is reasonably distributed, so that full stretching and realization of the maximal effect of each component are ensured; meanwhile, the bias belted aircraft tire keeps sidewise rigidity and stability of a body of the bias belted tire, and effectively improves the speed performance under high load through the wide-angle tread belt reinforcement layer and tire body reinforcement layers.
Description
technical field [0001] The invention relates to an aircraft tire, in particular to a belted bias aircraft tire with excellent speed performance under high load. Background technique [0002] The role of aviation tires is to support the load of the aircraft and undertake the functions of take-off, landing and taxiing, and must withstand the test of high load and high speed during use. Bias aviation tires are still the standard equipment of most aircrafts. Improving the speed performance of bias aviation tires under high loads and ensuring their safety are the key points of aviation tire design. At present, the methods we use to improve the speed performance of bias aviation tires are: 1. Increase the cutting angle of the carcass cord; 2. Use a large-angle reinforcing layer; 3. Use a full reinforcing layer on the tread; 4. Flat structure design. These methods have a certain effect on improving the speed performance of aviation tires, but for some small-sized civil aviation t...
