Abstract
The utility model provides a novel polyester cord aerotire which comprises a tire tread, a tire layer, a strengthening layer, a wire loop, filling adhesive and a sidewall adhesive. The novel polyester cord aerotire is characterized in that polyester cords form two or more than two carcass plies; the cords and the center line of the tire form an angle of 40 to 70 degrees; the carcass plies are cross-spreaded with each other; and the polyester cord at least forms one strengthening layer, and the strengthening layer and the center line of the tire form an angle of 30 to 55 degrees. Adopting polyester cords as the framework material of the tire layer and the strengthening layer, under the conditions of the same structure, the same vulcanization technique and the same inflation internal pressure, the novel polyester cord aerotire has a small outer margin as compared with the outer margin of a non-polyester cord tire, and the size of the outer margin of the tire has favorable stability during use; and the novel polyester cord aerotire with fewer tire layers and strengthening layers can bear the work pressure and airplane weight which are borne by more non-polyester cord tires.
Description
Technical field
The utility model relates to aircraft tyre, specifically is a kind of later-model polyester cord aircraft tyre.
Background technology
The size of aircraft tyre and weight all have strict demand, guaranteeing under the normal situation about using, the physical dimension of tire is more little, weight is light more good more, and in use, the physical dimension stability of tire also will be got well, can not increase, but make the aircraft tyre of framework material at present with nylon 66, nylon 6, just exist isostructural tire physical dimension bigger, the problem that physical dimension increases in the heavier and use of weight.Polyester cord modulus height, Heat stability is good, but in aircraft tyre, use, domestic still blank.
The utility model content
The purpose of this utility model is that a kind of isostructural tire will be provided, and physical dimension is less relatively, and weight is lighter relatively, and a kind of later-model polyester cord aircraft tyre of physical dimension good stability in use.
The utility model purpose realizes by following technical proposals:
The utility model comprises tyre surface, body piles, strengthening course, bead coil, filling glue and sidewall rubber, it is characterized in that: the casingply structure is made of the polyester cord more than 2 layers or 2 layers, its cord angle and tire line of centers are 40-70 °, arrangement intersected with each other between the carcass plies, the strengthening course structure is made up of one deck polyester cord at least, and strengthening course angle and tire line of centers are 30-55 °.
Described polyester cord is a prior art.
The employed polyester cord of the utility model is that disruption characteristic is not less than the 180N/ root, and breaking elongation is not less than 12% polyester cord.Polyester cord is provided with the elastic force parallel, and the elastic force parallel is continuous synthetic fibre long filament, and its disruption characteristic is not less than 2-5N/ root, and its elongation at failure is not less than 260%.
The beneficial effects of the utility model are: the aircraft tyre of doing the framework material manufacturing of body piles and strengthening course with polyester cord, under the condition of in identical structure, identical sulfuration process, identical inflation, pressing, the all more non-polyester cord tire of the physical dimension of later-model polyester cord tire is little, and the physical dimension good stability of tire in the use, can not increase, perhaps just can satisfy with less carcass, the reinforcement number of plies will be by the operating air pressure that tire bore and the aircraft weight of more non-polyester cord body piles, strengthening course.
In order to confirm the actual effect of the utility model tire, select same specification tire for use, the identical carcass number of plies sulfuration process identical with structure charges into identical interior pressure, carries out the contrast of the test of new tire physical dimension and tire dynamic analog test size, the results are shown in Table 1 and table 2.

Description of drawings
The aircraft tyre section structure scheme drawing that Fig. 1 makes with the polyester cord for the utility model.
Among the figure: 1. glue 6. bead coils are filled on tyre surface 2. crown strengthening courses 3. casingplies 4. sidewalls 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Consult Fig. 1, the utility model aircraft tyre mainly is made up of tyre surface 1, crown strengthening course 2, casingply 3, sidewall 4, filling glue 5 and bead coil 6.Outermost is a tyre surface 1, tread cap subordinate portion is a crown strengthening course 2, crown strengthening course 2 inner faces are casingply 3, crown strengthening course 2 usefulness 1670 (1 * 30) dtex/2 polyester cords constitute, its cord angle and tire line of centers are 40 ° of arrangements, and casingply 3 is made of the polyester cord more than 2 layers or 2 layers at least.The utility model casingply 3 is 6 layers, 4 layers of internal layer carcass plies from the lining outside anti-package cross bead coil 6, in addition, outer carcass plies has 2 layers of cord just wrapping bead coil 6 from outside to inside to tire toe position, carcass internal layer and outer cord all use 1670 (1 * 30) dtex/2 polyester cord to constitute, body cord angle and tire line of centers are 55 °, are between each layer carcass plies to intersect to arrange.
Each is made up of two bead coils 6 about bead part, and bead coil 6 section forms are square.
Be provided with the bead apex 5 that is the triangular cross-section shape on bead coil 6, this is filled glue and adopts hard rubber, is preferably the above dynamic modulus of elasticity sizing material of 45Mpa, and Shore A hardness is 80 degree, and its bead apex height is 40% of a tire section height.
