Abstract
The invention involves an all-steel Meridian tire with transition strengthening layer. The Meridian tire installs at least one layer transition strengthening layer which is used for protecting carcass ply layer metal or non-metallic cord on the tire side bending area out of the carcass ply layer, the circumferential angle of transition strengthening layer cord is of 40 to 80 degree; when the transition strengthening layer is two layers or more, the cords of adjacent transition strengthening layer are installed in cross status. The Meridian tire has small distortion degree and strong carrying capacity when car runs; and due to the transition strengthening layer can prevent carcass ply layer from damaged by impaling and cutting, so it solves the problem of carcass is easy to be layered caused by carcass ply layer steel wire cords staining effectively, increases the durability of heavy vehicle tires and the use safety.
Description
(1) technical field:
The present invention relates to a meridian line tyre, relate in particular to a kind of all-steel meridian engineered tyre that has transitional reinforced layer that is used for the giant-scale engineering automobile.
(2) background technology:
Existing giant-scale engineering automobile all-steel radial tyre is to adopt steel cord to make framework material, because the recovery of elasticity of steel cord is splendid, therefore is fit to the high load capacity load-carrying and runs at high speed.But because this meridian line tyre only has one deck casingply, rely on carcass rubber to connect between the casingply steel cord, therefore, heavier or when running at high speed when the automobile load, because tire carcass is extruded, the stressed generation of rubber between steel cord is extended, spacing between steel cord is broadened, thereby cause the tire modification, owing to only rely between the casingply steel cord rubber to connect, when the rubber that runs between sharp object puncture or the cutting casingply steel cord, very easily rubber is punctured or cuts, cause damaged tyres, the tire running safety multiple is reduced greatly.And sharp object also easily damage be covered in steel cord outer carcass rubber layer and steel cord itself, make outside steel cord is exposed to, easy corrosion causes delamination, thereby has further reduced tyre capacity.
(3) summary of the invention:
It is strong that the present invention will disclose a kind of load-carrying capacity, the radial tyre that has transitional reinforced layer of anti-puncture and cutting.
For achieving the above object; the present invention has adopted following technical scheme: originally have the all-steel meridian engineered tyre of transitional reinforced layer with existing radial tyre different be; this meridian tire is bent around the district on the sidewall in the casingply outside; be provided with the transitional reinforced layer that is used to protect the casingply steel cord; described transitional reinforced layer is made of metal or non-metal cord; the circumferential angle of the metal of transitional reinforced layer or non-metal cord is between 40～80 °; the preferable selection of the metal of transitional reinforced layer or the circumferential angle of non-metal wire is between 50～70 °; when the circumferential angle of the metal of transition enhancement Layer or non-metal wire was 55～65 °, it is best that its effect reaches.Transitional reinforced layer can be one deck, also can be two-layer or two-layer more than, cross-shaped setting between the metal of adjacent transitional reinforced layer or the non-metal wire; Transitional reinforced layer is generally positioned at the sidewall and bends around the district, it is arranged at the sidewall bends best results when distinguishing near tire shoulder portion.
The present invention makes automobile in motion owing to adopted above technical scheme, and variation and tire side modification degree that steel cord is extruded time interval reduce, and then tire capacity is strengthened; And because transitional reinforced layer can protect casingply can not be damaged because of puncture, cutting etc.; cause the problem of carcass layering thereby solved effectively, improved the durability of tyre of heavy truck and the safety of use because of the casingply steel cord gets rusty.

Fig. 1 is the structural representation of one embodiment of the present invention;
Fig. 2 is the structural representation of another embodiment of the invention.
Reference numeral: crown district 1; Shoulder area 2; Bend around district 3 on the sidewall; Bead region 4; Transitional reinforced layer 5; Casingply 6; Steel bead wire 7; Cord anti-package part 8.
(5) specific embodiment:
Accompanying drawing of the present invention is not to draw in proportion, and it only is used to illustrate the present invention.Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
In embodiment shown in Figure 1, the present invention includes carcass, carcass is followed successively by crown district 1, shoulder area 2, sidewall from top to bottom and bends around district 3 and bead region 4.Be provided with casingply 6 in the carcass, casingply 6 is outwards walked around steel bead wire 7 bottoms anti-package upwards again from steel bead wire 7 inboards, form cord anti-package part 8, the outside at casingply 6, be provided with the two-layer transitional reinforced layer 5 that is used to protect casingply 6 metals or non-metal cord, the circumferential angle of transitional reinforced layer 5 cords is between 40～80 °; But it is cross-shaped between the two-layer cord of two-layer transitional reinforced layer 5.In the present embodiment, it is in the wrong in district 3 that transitional reinforced layer 5 is arranged at the sidewall.
At embodiment shown in Figure 2, the radial tyre that originally has excessive enhancement Layer is provided with the transitional reinforced layer 5 that one deck is used to protect casingply 6 steel cords in the outside of casingply 6, and the circumferential angle of transitional reinforced layer 5 cords is between 40～80 °.In the present embodiment, transitional reinforced layer 5 is arranged at the sidewall and bends the 3 close tire shoulder portion places around the district.
In the specific embodiment of the present invention, transitional reinforced layer can be one deck or two-layer as embodiment 1,2 not only, as required, also can be for more than three layers or three layers, the circumferential angle of the metal of transitional reinforced layer or non-metal cord also can be adjusted between 40～80 °, and is cross-shaped between each layer cord when adopting two-layer above transitional reinforced layer.
