Abstract
The invention discloses a kind of carcass enhancement mode radial, including crown, tire shoulder, carcass cord casing ply, sidewall and tyre bead.Outside carcass cord casing ply or inside carcass cord casing ply or carcass cord casing ply inner side and outer side of the present invention is provided with strengthening course, solve tire and carry or easily cause under shock loading upper sidewall explosion or the problem making upper sidewall become tire blow-out starting point at high pressure height, enhance tire and adapt to the ability of harsh use condition, can effectively prevent earlier period damage, extend the service life of tire.
Description
Technical field
The present invention relates to a kind of tire, particularly a kind of carcass enhancement mode tire.
Background technology
Present all-steel radial tyre, especially all-steel load-bearing radial tire, the steel wire of carcass cord casing ply from tyre bead to upper sidewall until crown becomes radial distribution, steel wire and steel wire gap from tyre bead to upper sidewall until crown incrementally increases, upper sidewall and crown region steel wire density relatively tyre bead portion reduce, upper sidewall intensity is caused to reduce, and crown zone is owing to there being circumferential belt banding effect to make its intensity not decline, therefore tire product carries or under shock loading at high pressure height, easily cause upper sidewall explosion or make upper sidewall become the starting point of tire blow-out, shorten the service life of tire.
At present, the tire strengthening sidewall intensity has several form.Wherein, Chinese patent CN202294098U discloses a kind of tire side protecting type tire; this tire is provided with protective layer outside sidewall; and protective layer is integral structure with sidewall; solve off-the-road tyre the most particularly in the problem using the mining area protection carcass internal material of inclement condition to be easily scraped off, it is impossible to enough prevent tire carry at high pressure height or easily cause upper sidewall explosion under shock loading or make upper sidewall become the starting point of tire blow-out；Chinese patent CN203063589U discloses a kind of sidewall enhancement mode tire, this tire increases enhancement layer inside sidewall, the wall thickness making sidewall strengthens, ensure that sidewall tool has good wearability, solve on hill path, travel the problem that cover tire is difficult to gall, tire can not be solved and carry or easily cause under shock loading upper sidewall explosion at high pressure height or make upper sidewall become the problem of starting point of tire blow-out；Chinese patent CN202345302U discloses the anti-fried off-the-road tyre in a kind of sidewall, between adjacent anti-package casing ply, free casing ply is set, free casing ply not anti-package wire loop and triangle rubber and play cushioning effect, these free casing plies not only strengthen the intensity of carcass, the most important thing is to have disperseed the fatigue stress of carcass, thus efficiently solve tire and explode sidewall problem, but the program is served only between the multi-layer cord fabric layer of oblique engineering machinery tire, overall heat is bigger, it is impossible in the radial of only layer of steel wire carcass.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of carcass enhancement mode tire, thus strengthens the casingply intensity of upper sidewall.
For solving the problems referred to above, the technical solution adopted in the present invention is outside casingply or inside casingply or casingply inner side and outer side is provided with strengthening course.Described strengthening course is made up of the complex of fiber with rubber, and thickness is 0.5 ~ 2.5mm, can be 1 ~ 6 layer, and its overlay area is shoulder portion at the 1/5 ~ 3/5 of tire section height.
The invention has the beneficial effects as follows when tire product carries or under shock loading at high pressure height, owing to outside carcass casingply or inside casingply or casingply inner side and outer side is coated with strengthening course, add the casingply intensity of upper sidewall, thus avoid upper sidewall explosion or make upper sidewall become the starting point of tire blow-out, extend the service life of tire.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail, wherein:
Fig. 1 is structural representation of the prior art；
Fig. 2 is the structural representation of the first embodiment of the present invention；
Fig. 3 is the structural representation of the second embodiment of the present invention；
Fig. 4 is the structural representation of the third embodiment of the present invention.
Detailed description of the invention
Fig. 2 to Fig. 4 shows three kinds of embodiments of the present invention.
Embodiment 1:
As shown in Figure 2, a kind of carcass enhancement mode tire, including crown 1, tire shoulder 2, carcass cord casing ply 3, sidewall 4 and tyre bead 5, is provided with strengthening course 6 outside carcass cord casing ply 3, thickness is 0.5 ~ 2.5mm, and overlay area is shoulder portion at the 1/5 of tire section height.When tire is under high pressure high load or shock loading, due to the effect of strengthening course 6, enhance the casingply intensity of upper sidewall, thus avoid upper sidewall explosion or make upper sidewall become the starting point of tire blow-out.
Embodiment 2:
As shown in Figure 3, a kind of carcass enhancement mode tire, including crown 1, tire shoulder 2, carcass cord casing ply 3, sidewall 4 and tyre bead 5, is provided with strengthening course 7 inside carcass cord casing ply 3, thickness is 0.5 ~ 2.5mm, and overlay area is shoulder portion at the 3/5 of tire section height.When tire is under high pressure high load or shock loading, due to the effect of strengthening course 7, enhance the casingply intensity of upper sidewall, thus avoid upper sidewall explosion or make upper sidewall become the starting point of tire blow-out.
Embodiment 3:
As shown in Figure 4, a kind of carcass enhancement mode tire, including crown 1, tire shoulder 2, carcass cord casing ply 3, sidewall 4 and tyre bead 5, is respectively provided with one layer of strengthening course 6,7 with inner side outside carcass cord casing ply 3, thickness is 0.5 ~ 2.5mm, and overlay area is shoulder portion at the 1/2 of tire section height.When tire is under high pressure high load or shock loading, due to the effect of strengthening course 6 and 7, enhance the casingply intensity of upper sidewall, thus avoid upper sidewall explosion or make upper sidewall become the starting point of tire blow-out.
Above in conjunction with accompanying drawing, embodiments of the present invention are explained in detail, but the present invention is not limited to above-mentioned embodiment, in the ken that those skilled in the art is possessed, it is also possible to it is made many variations.
