Abstract
The utility model discloses the long-lived aircraft tyre of a kind of bead, comprise tyre bead, chafer, tire toe, wheel rim, it is characterized in that: be provided with two-layer chafer at tyre bead portion, be divided into outer chafer and internal layer chafer; Wherein, internal layer chafer bag is to tire toe place, and outer chafer wraps up whole tyre bead; One deck hard film is folded with between the outer chafer and internal layer chafer at wheel rim position.By increasing the chafer number of plies and arrange the hard film of wear resisting property excellence between the outer chafer and internal layer chafer at bead position, thus increase the thickness of bead position protective cover, improve the durability of bead.
Description
Technical field
The utility model belongs to aircraft tyre field, is specifically related to the long-lived aircraft tyre of a kind of bead.
Background technology
At present, aircraft tyre generally only arranges one deck chafer, and its effect is that protection tyre bead corrodes from mechanical damage and foreign object.Because aircraft tyre load is high, deflection ratio is large, in use procedure, bead is constantly subject to strong extruding and the friction of wheel rim, cause aircraft tyre often to occur injuring body cord because of bead undue wear and then affect the later stage turning over news, thus improving bead durability is the important guarantee improving aircraft tyre service life.
Utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, provides a kind of bead long-lived aircraft tyre.
The technical scheme realizing the utility model object is:
The long-lived aircraft tyre of a kind of bead, comprises tyre bead, chafer, tire toe, wheel rim, unlike the prior art: be provided with two-layer chafer at tyre bead portion, is divided into outer chafer and internal layer chafer; Wherein, internal layer chafer bag is to tire toe place, and outer chafer wraps up whole tyre bead; One deck hard film is folded with between the outer chafer and internal layer chafer at wheel rim position.
Described hard film is that thickness is 0.6mm ~ 1.2mm and has the hard film of excellent wear-resisting property.
Good effect of the present utility model is: by increasing the chafer number of plies and arrange the hard film of wear resisting property excellence between the outer chafer and internal layer chafer at bead position; thus increase the thickness of bead position protective cover, improve the durability of bead and the durability of tire.
Accompanying drawing explanation
Fig. 1 is chafer structural representation of the present utility model.
In figure: A: hard film; B: outer chafer; C: internal layer chafer; D: tyre bead; E: tire toe; F: wheel rim.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further details.
With reference to Fig. 1, the long-lived aircraft tyre of a kind of bead, comprises hard film A, outer chafer B, internal layer chafer C, tyre bead D, tire toe E, wheel rim F, and bead is tyre bead D top and wheel rim F contact position.Tyre bead D is provided with two-layer chafer (i.e. outer chafer B and internal layer chafer C), between the outer chafer B and internal layer chafer C at bead position, be provided with a layer thickness be 0.6mm ~ 1.2mm and the hard film A with excellent wear-resisting property, internal layer chafer C only extends to tire toe E place, and whole tyre bead D then wraps by outer chafer B.
