Abstract
The invention discloses a steel-belted aerial tire with the skeleton material of nylon-kelvar composite cord, which is mainly characterized in that the carcass ply is composed of multi-layer nylon 66 cords or nylon-kelvar composite cords. The belt structure layer is composed of at least more than two layers of nylon-kelvar composite cords. A tire tread structure layer is arranged above the belt structure layer, in which the nylon-kelvar composite cord is also applied. Both ends of the carcass ply cord layer are wound with a pair of left and right wire loops and counter wrapped upward. The belt structure layer is composed of the invert folded cords, in which the curling ends are all in the middle of the tread of tire. This aerial tire has the advantages that (1) the nylon-kelvar composite cord is taken as the skeleton material of the tire so that the fine characteristics of the nylon-kelvar composite cords are reflected, in which a good basis is laid in order to meet the using requirements of the steel-belted aerial tire. (2) With the belt structure layer of multi-layer nylon-kelvar composite cords, the high internal pressure, high-speed, high-load, large deformation and impact resistant use requirements of the steel-belted tire can be met.
Description
Technical field:
The present invention relates to the framework material of aircraft tyre and tire, particularly a kind of meridian aviation tyre with nylon/aramid fiber composite cord as framework material.
Background technology:
The handling characteristics of meridian aviation tyre be press in high, high-speed, top load, large deformation (deflection ratio reaches 28%～40%), shock resistance, intermittent use.Requirements such as the high strength that the cord that has been determined to use by the mechanical property of meridian aviation tyre and harsh usage condition thereof must have, endurance, shock-resistant, resistance to deformation.
At present, top load, inflate the most carcasses of aircraft tyre technology at a high speed and adopt cross one another oblique configuration, the master tape bundle also adopts the oblique belt structure, when the aircraft tyre of this structure uses under top load, high-speed harsh conditions, reason owing to the body cord orientation, make under the centrifugal action that tire produces at high speed revolution, make tyre surface produce nonvolatil dilatational strain.The rigidity at tyre surface position is low, and speed ability is low, and resistance to abrasion is bad, Sheng Regao, superior speed ability and the durability of extremely difficult acquisition.In addition, tyre framework material mainly is nylon 66, nylon 6 at present, and the shortcoming of nylon is thermo-labile, and thermal contraction is big, modulus is little, and percentage elongation is big.
Summary of the invention:
The objective of the invention is provides a kind of with nylon/aramid fiber composite cord as framework material for overcoming the deficiencies in the prior art, can satisfy high in pressure, at a high speed, the meridian aviation tyre of top load, large deformation, shock resistance operating needs.
The present invention includes tyre surface, carcass, belt structure layer, string of a hat Structural layer, fill glue, bead coil, unlike the prior art be: the carcass plies of carcass is made by two-layer at least above nylon 66 cords or nylon/aramid fiber composite cord, arrangement intersected with each other between the carcass plies, the two ends of casingply are around the pair of right and left bead coil anti-package that makes progress, and the circumferential angle of its cord and tire is 60 °～90 °.The tire belt Structural layer is fitted by two-layer at least above cord and is constituted, encase the internal layer carcass plies behind the reflexed of outer cord both sides, and the seamed end of belt structure layer is all in the middle of crown, belt structure layer cord and tire circumferentially form 0 °～30 ° angles, be furnished with the tyre surface string of a hat Structural layer that cord and tire circumferentially are 0 °～5 ° of angles above this belt structure layer, string of a hat Structural layer is made of one deck or two-layer above cord.Belt structure layer and string of a hat Structural layer all use nylon/aramid fiber composite cord.
Described nylon/aramid fiber composition fiber cord is spun and is twisted into by nylon, the aramid fiber rationed shares, and rationed shares ratio is a nylon: aramid fiber=1: 2.Nylon/aramid fiber composite cord, it is thermo-labile to have covered single nylon fiber, thermal contraction is big, modulus is little, percentage elongation big and aramid fiber and the not high shortcoming of rubber adhesion degree, and concentrate kept aramid fiber modulus of elasticity height, good heat resistance, in light weight, percentage elongation is little and nylon and the high advantage of rubber adhesion degree, make composite cord possess high-modulus, high heat-resisting, low-shrinkage, good strength and toughness and fatigue durability and the characteristic high with the rubber adhesion degree can satisfy the operating needs of meridian aviation tyre high speed top load.
The invention has the advantages that: (1) uses nylon/aramid fiber composite cord to make the framework material of tire, can embody the good characteristic of nylon/aramid fiber composite cord, for the operating needs that satisfies meridian aviation tyre is had laid a good foundation; (2) multilayer nylon/aramid fiber composite cord string of a hat Structural layer and belt structure layer can satisfy in the meridian aviation tyre height and press, and be high-speed, top load, large deformation, shock proof operating needs; (3) the belt structure layer structure of crimping can prevent the distortion that produces when the ground connection because of tire, cause the cord end to produce bigger shear strain, if belt structure layer cord termination is exposed outside, then stress is concentrated and is caused the danger that generation is peeled off between cord and the sizing material easily.By the end of winding belt structure layer, can prevent the generation of peeling off between cord termination and the sizing material; (4) the used cord of belt structure layer is that nylon/aramid fiber organic fibrous material is made.Because its cord has heat-shrinkable, when tyre vulcanization heats, will vertically produce thermal shrinkage stress, thereby improving the initial tension that the cord in the circumferential belt structure layer is depressed in uncharge inflation, this will play the effect that suppresses standing wave effectively.
Description of drawings:
Fig. 1 is the generalized section of radial-ply tyre of the present invention.
The specific embodiment:
With reference to Fig. 1, meridian aviation tyre of the present invention is by comprising tyre surface 1, string of a hat Structural layer 2, belt structure layer 3, carcass 4, filling glue 5, bead coil 6.The carcass plies of carcass 4 is formed with multilayer organic fiber cord, and the outside anti-package bead coil 6 from the lining wherein has at least one deck organic fiber carcass plies outside in to wrap bead coil 6 and constitutes, and the circumferential angle of body cord and tire is 60 °～90 °.In the bizet position of tire belt structure layer 3 and string of a hat Structural layer 2 are set, belt structure layer 3 has at least two-layer cord to form, the circumferential angle of belt structure layer cord and tire is 0 °～30 °, in order to reduce the inter-laminar shears stress concentration of belt structure layer termination, having one deck bracing ply at least is the winding structure, and the seamed end of belt structure layer is all in the middle of crown.Above this belt structure layer 3, be furnished with the circumferential angle of cord and tire and be 0 °～5 ° tyre surface string of a hat Structural layer 2, form by two-layer cord.Belt structure layer 3 and string of a hat Structural layer 2 all are compounded with the organic fiber cord with nylon/aramid fiber and form.Dispose bead apex 5 at the casingply turnup.
