Abstract
The invention discloses an optimized back-packaging radial tire. The optimized back-packaging radial tire comprises a tire body, a steel wire ring and a rubber core, wherein the rubber core is connected to the upper end of the steel wire ring, the tire body comprises a tire body main body part and a tire body back-packaging part, the tire body main body part is located at the inner side of the tire and extends to the steel wire ring, and the tire body back-packaging part extends from the tire body main body part and bypasses the steel wire ring so as to backwards package the outer side of the tire body. The optimized back-packaging radial tire is characterized in that the tire body back-packaging part is provided with a bending part, and the undulant bending part is preferably selected; a conventional linear type tire body back-packaging structure is transformed into a curved tire body back-packaging structure with the bending part, so that when a tire bead structure is subjected to tensile strain, the bending tire body back-packaging part can be subjected to tensile strain simultaneously, and therefore, the stress transition of the tire body back-packaging part is relatively good; meanwhile, the stress concentration of a tire body back-packaging endpoint is reduced, and thus the performance of the radial tire is improved, and the service life of the radial tire is prolonged.
Description
Technical field
The present invention relates to tyre technology, be specifically related to a kind of radial-ply tyre of optimizing anti-package design.
Background technology
The key point of radial-ply tyre performance quality mainly contains two parts: the one, and the structure design of tire, the 2nd, the selecting of tire material.The particularly structure of radial-ply tyre, tire construction reasonable in design can make the abilities such as the resistance to compression tension of radial-ply tyre obviously be strengthened, and Using Life of Tyre is increased.The patent application that for example application number is CN201220408348.0, discloses a kind of full steel engineering radial-type tyre of carcass ply bound edge, can effectively avoid carcass anti-package end points place sidewall breach, extends Using Life of Tyre.
At present, the anti-package structure of general radial-ply tyre is linear pattern or near linear type, because body cord can not be stretched, present very strong rigidity, in the time of tyre bead portion generation stretcher-strain, transition is inhomogeneous, particularly, at anti-package end points place, cause earlier period damage because stress is concentrated, affected the performance and used life of radial-ply tyre.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of radial-ply tyre of optimizing anti-package design, can make the transition of stress at carcass anti-package position better, reduces the stress of carcass anti-package end points and concentrates, thereby improve tyre performance and service life.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of radial-ply tyre of optimizing anti-package design, comprise carcass, bead coil and glue core, glue core is connected in bead coil upper end, carcass comprises carcass main part and carcass turnup, carcass main body section is in tire inner side and extend to bead coil, carcass turnup extends and walks around the outside of bead coil anti-package to tire from carcass main part, and its difference is: described carcass turnup is provided with sweep.
Preferably, described sweep is the waveform of fluctuating, so that tensile property is better.
Preferably, described carcass turnup is wrapped with steel wire infantees, to improve the rigidity of bead structure.
Preferably, described glue core is made up of the flexible glue portion on top and the ebonite portion of bottom, so that stress transition on glue core is more even.
The stress producing due to External Force Actings such as tire stretchings focuses mostly in the epimere of carcass turnup, so described sweep is preferably arranged at the epimere of carcass turnup.
Compared to the prior art, advantage of the present invention is:
The present invention is the shaped form carcass anti-package structure with sweep by traditional linear pattern tire carcass anti-package structural development, in the time of bead structure generation stretcher-strain, can there is stretcher-strain in bending carcass turnup simultaneously, therefore make the transition of stress of carcass turnup better, the stress that simultaneously reduces carcass anti-package end points is concentrated, thereby has improved the performance and used life of radial-ply tyre.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Number in the figure is: 1, carcass; 1-1, carcass turnup; 1-2, carcass main part; 2, steel wire infantees; 3, bead coil; 4, glue core; 4-1, flexible glue portion; 4-2, ebonite portion.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, the optimization of the present embodiment the radial-ply tyre of anti-package design, comprise carcass 1, steel wire infantees 2, bead coil 3 and glue core 4, glue core 4 is connected in bead coil 3 upper ends, carcass 1 comprises carcass main part 1-2 and carcass turnup 1-1, carcass main part 1-2 is positioned at tire inner side and extends to bead coil 3, carcass turnup 1-1 extends and walks around the outside of bead coil 3 anti-packages to tire from carcass main part 1-2, it has encased one end that bead coil 3 and glue core 4 are connected with bead coil 3, steel wire infantees 2 is wrapped in outside carcass turnup 1-1, its improvements are: described carcass turnup 1-1 is provided with and is sweep, described sweep is the waveform of fluctuating.
Wherein, the 4-2 of ebonite portion of 4 4-1 of flexible glue portion by top of described glue core and bottom forms; Described sweep is arranged at the epimere of carcass turnup 1-1, is close to the outside of flexible glue portion (4-1).
