Abstract
The utility model discloses an improved engineering radial tire which comprises a tire body which is sequentially divided into a tire crown region, a tire shoulder region, a tire lateral bending region and a tire bead region from top to bottom, wherein a carcass ply is arranged in the tire body, outwards surrounds the bottom of a tire bead steel wire from the inner side of the tire bead steel wire and then upwards backwards wraps to form a carcass ply backwards-wrapping part, and is of a local dual-layer structure, a dual-layer part of the carcass ply is arranged in the tire lateral bending region, the head of the carcass ply backwards-wrapping part is arranged in the tire lateral bending region, and a reinforcing block is arranged on a tire lateral glue part of the tire lateral bending region and corresponds to the end head of the carcass ply backwards-wrapping part. According to the improved engineering radial tire, the rigidity and the bending resistance of the tire lateral bending region are improved, the durability and the use safety of the heavy automobile tire are improved, the production cost is saved, and a certain economic benefit is obtained.
Description
Technical field
The utility model relates to a meridian line tyre, relates in particular to a kind of improved type meridian engineered tyre for giant-scale engineering automobile.
Background technology
Existing giant-scale engineering automobile all-steel radial tyre is to adopt steel cord to make framework material, because the elasticity of steel cord recovers splendid, is therefore applicable to high load capacity load-carrying and runs at high speed.But because this meridian line tyre only has one deck casingply, between casingply steel cord, rely on carcass rubber to connect, therefore, in the time that automobile load is heavier or run at high speed, because tire carcass is extruded, the stressed generation of rubber between steel cord is extended, spacing between steel cord is broadened, thereby cause tire modification, owing to only relying on rubber to connect between casingply steel cord, in the time running into sharp object puncture or cut the rubber between casingply steel cord, very easily rubber is punctured or cut, cause damaged tyres, tire running safety multiple is reduced greatly.And sharp object also easily damage be covered in carcass rubber layer and steel cord itself outside steel cord, make outside steel cord is exposed to, easily corrosion, causes delamination, this phenomenon bend on sidewall in plot structure, show the most outstanding.
For tackling above-mentioned deficiency, put forward the performance in Qu Rao district, sidewall, have enterprise to take to improve with multilayer carcass metal-cord, cause the increase of cost, use multilayer carcass metal-cord also to exist tire longitudinal rigid is strengthened simultaneously, cause the problems such as the elasticity of flat direction weakens.Also have at carcass metal-cord enhancement Layer scheme is set outward, if but because of the little effect that does not have reinforcing property of enhancement Layer thickness, enlarged in thickness also easily causes Qu Rao district, sidewall integral thickness to increase and produces new problem.
Utility model content
The purpose of this utility model, provides sidewall is bent and carried out improved a kind of improved type meridian engineered tyre around plot structure.
The purpose of this utility model is achieved in that a kind of improved type meridian engineered tyre, comprise carcass, carcass is divided into crown zone from top to bottom successively, shoulder area, Qu Rao district, sidewall and bead region, in carcass, be provided with casingply, casingply is outwards walked around steel bead wire bottom anti-package upwards again from steel bead wire inner side, form carcass ply anti-package part, described casingply is local double layer structure, casingply double portion is divided and is arranged in Qu Rao district, sidewall, the termination portion of carcass ply anti-package part is arranged in Qu Rao district, sidewall, the sidewall rubber part in Qu Rao district, sidewall corresponding to the termination of carcass ply anti-package part is provided with boss.
The utility model can also be the position that the termination portion of described carcass ply anti-package part is arranged on upper end in Qu Rao district, sidewall and approaches shoulder area.
The beneficial effects of the utility model are: improve sidewall Qu Rao district rigidity and anti-flexural property; effectively prevent the damage of ftractureing to sidewall rubber part in the termination of carcass ply anti-package part; protection Qu Rao district, carcass sidewall curtain carcass layer of cloth can not be damaged because of puncture, cutting etc.; the durability of tyre of heavy truck and the safety of use are improved; save productive costs, had certain economic benefit.
Brief description of the drawings
Fig. 1 is the utility model cross-sectional view.
Wherein 1 crown zone, 2 shoulder areas, 3 Qu Rao districts, sidewall, 4 bead regions, the double-deck part of 5 carcass plies, 6 casingplies, 7 steel bead wires, 8 carcass ply anti-package parts, 9 bosses.
Detailed description of the invention
