Abstract
The utility model discloses a bead reinforcement structure of a pneumatic tyre. A cord fabric bypasses from the bottom of a bead core from inside to outside, turns upward and wraps and contains the bead core and a bead filler, wherein the bead filler is arranged above the bead core, the part, turning upward, of the cord fabric is a cord fabric rolled edge, bead reinforcement yarns are arranged outside the cord fabric rolled edge, lengths of the bead reinforcement yarns are in the range of from 25 to -90mm, thicknesses of the bead reinforcement yarns are in the range of from 0.7 -to1.5mm, distance between the lower end of each bead reinforcement yarn and the upper end of the bead core ranges from -5mm to +5mm, the distance between the upper end of each bead reinforcement yarn and the upper end of the bead filler which are staggered is at least 3mm, after the bead reinforcement yarns are added, bead rigidity is enhanced, bead deformation is reduced, a deformation interval is moved to a tyre shoulder, the tyre shoulder is the thinnest part of a tyre and material endpoints are fewer, deformation absorption and heat dissipation can be facilitated, the phenomenon that a part with the maximum section width or below is damaged in advance can be avoided, life of the tyre is prolonged, and durability and walking performance without wind pressure are enhanced.
Description
Technical field
The utility model relates to a kind of pneumatic tire structure, especially a kind of tire lip reinforced structure that promotes the performance of running stability of run-flat tire under zero blast condition.
Background technology
Existing run-flat tire (Run-flat tire) only depends on triangle rubber to carry out the supporting tire lip, when calm pressure condition traveling, tire lip undercapacity, easily cause maximum disconnected wide 1 or following stress to be concentrated, cause that tyre bead reinforcement rubber layer 2, triangle rubber 3, cord lock ups 4 and the mutual stress of tyre bead glue 5 increase, and cause early damage.
The utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of airtyred tire lip reinforced structure, this airtyred tire lip reinforced structure increases one deck tire lip reinforcement yarn at the tire lip and carries out reinforcement, can the tire shoulder part will upwards be transferred between deforming zone, be beneficial to deflection transition and heat radiation, avoid maximum disconnected wide or following destruction in advance, promote the performance of running stability under zero blast condition.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of airtyred tire lip reinforced structure, cord from the bottom of tire lip core, walks around from inside to outside and the turnup bag that makes progress is put tire lip core and triangle rubber, described triangle rubber is positioned at described tire lip core top, the make progress part of turnup of described cord is cord lock ups, the outside of described cord lock ups is provided with tire lip reinforcement yarn, the length range of described tire lip reinforcement yarn is 25～90mm, the thickness range of described tire lip reinforcement yarn is 0.7～1.5mm, the distance range of the lower end of described tire lip reinforcement yarn and the upper end of tire lip core is-5～+ 5mm, the distance staggered in the upper end of described tire lip reinforcement yarn and the upper end of described triangle rubber is 3mm at least.
The beneficial effects of the utility model are: airtyred tire lip reinforced structure of the present utility model is mainly to be provided with tire lip reinforcement yarn in the outside of cord lock ups, the length range of tire lip reinforcement yarn is that 25～90mm and thickness range are 0.7～1.5mm, the lower end of tire lip reinforcement yarn and the distance range of tire lip core be-5～+ 5mm, at least 3mm staggers between the upper end of tire lip reinforcement yarn and the upper end of triangle rubber, after increasing this tire lip reinforcement yarn, strengthened tire lip rigidity, reduce the distortion of tire lip, the tire shoulder place will be moved between deforming zone, the tire shoulder place is originally few as tire thinnest part and material end points, be beneficial to and absorb distortion and heat radiation, avoid maximum disconnected wide or following destruction in advance, extend tire life, lifting durable performance of running stability during without blast.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below, by the particular specific embodiment accompanying drawings specific embodiment of the present utility model, those skilled in the art can understand advantage of the present utility model and effect easily by content disclosed in the present specification.The utility model also can other different mode be implemented, and, under the category do not disclosed departing from the utility model, can give different modifications and change that is.
Embodiment: a kind of airtyred tire lip reinforced structure, cord from the bottom of tire lip core 7, walks around from inside to outside and the turnup bag that makes progress is put tire lip core 7 and triangle rubber 3, described triangle rubber 3 is positioned at described tire lip core 7 tops, the make progress part of turnup of described cord is cord lock ups 4, the outside of described cord lock ups 4 is provided with tire lip reinforcement yarn 6, the length H scope of described tire lip reinforcement yarn is 25～90mm, the thickness range of described tire lip reinforcement yarn is 0.7～1.5mm, the distance A scope of the lower end of described tire lip reinforcement yarn and the upper end of tire lip core is-5～+ 5mm, the distance L staggered in the upper end of described tire lip reinforcement yarn and the upper end of described triangle rubber is 3mm at least.
Above-described embodiment is only illustrative the utility model principle and effect thereof, but not for limiting the utility model.Rights protection scope of the present utility model, should be as listed as claims.
