Abstract
The utility model provides a kind of run-flat tire, comprise carcass, carcass is divided into crown zone, shoulder area, sidewall district and bead region, carcass cord carcass plies is provided with in carcass, bead region has the steel bead wire buried underground wherein, after carcass cord carcass plies walks around steel bead wire bottom reversed, its external end head radially upwards extends one section, the cross sectional shape be provided with inside the district of described sidewall along tire radial direction is the reinforcement rubber layer of crescent shape, the both sides being positioned at the carcass cord carcass plies in described sidewall district are respectively arranged with outer circumferential reinforcement and internal layer circumference reinforcement, this outer circumferential reinforcement and internal layer circumference reinforcement contiguous mutually and almost parallel.The utility model, by arranging double-deck circumferential reinforcement in sidewall district, coordinates original reinforcement rubber layer, significantly strengthens and keeps the support strength of tire, when guaranteeing tire flat can not shrivel by vehicle weight, improve the robustness of tire.
Description
Technical field
The utility model relates to tyre technology, is specifically related to a kind of run-flat tire.
Background technology
The safety of tire to automobile is most important, once blow out or punctured rapid gas leakage, is just easy to cause traffic accident, especially when galloping.Tire is once gas leakage will be out of shape and be reduced, and automobile will the inclined side of lack of equilibrium, the uncontrollable direction of chaufeur and braking.So, keep the normal tire pressure of motor tire, very important for vehicle safety travel.But it is not rare thing that tire is pricked gas, if not know or do not have spare tyre or oneself can not change tire will be very passive.Therefore, most of car owner fears tire flat, and not only safety is on the hazard, and change tire by the road is also a pretty troublesome thing temporarily.
Some tiremakers the sixth of the twelve Earthly Branches is through being proposed the tire with run-flat function, to be pricked or other reason is leaked gas in generation, still the ability of self can be relied on to make running car one long distance, reach repairable place or residence, safer when people are driven a car.
Often adopt in the market, in sidewall district, reinforcement rubber layer is set to strengthen the support strength of tire, realize the function of run-flat, but ageing of rubber speed, adopt separately rubber layer to strengthen support strength, can not practical effect be ensured.
Utility model content
The utility model provides a kind of run-flat tire with multiple reinforcement structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of run-flat tire, comprise carcass, carcass is divided into crown zone, shoulder area, sidewall district and bead region, carcass cord carcass plies is provided with in carcass, bead region has the steel bead wire buried underground wherein, after carcass cord carcass plies walks around steel bead wire bottom reversed, its external end head radially upwards extends one section, the cross sectional shape be provided with inside the district of described sidewall along tire radial direction is the reinforcement rubber layer of crescent shape, the both sides being positioned at the carcass cord carcass plies in described sidewall district are respectively arranged with outer circumferential reinforcement and internal layer circumference reinforcement, this outer circumferential reinforcement and internal layer circumference reinforcement contiguous mutually and almost parallel.
Further, sizing material is filled with in the space between the circumferential reinforcement of described skin and internal layer circumference reinforcement.
Preferably, the horizontally-arranged width that the circumferential reinforcement of described skin and internal layer circumference reinforcement are formed covers sidewall district overall with.
Preferably, the circumferential reinforcement of described skin and internal layer circumference reinforcement all adopt annular cord.
Further, radial reinforcement is also provided with in the district of described sidewall.
From above technical scheme, the utility model, by arranging double-deck circumferential reinforcement in sidewall district, coordinates original reinforcement rubber layer, significantly strengthens and keeps the support strength of tire, when guaranteeing tire flat can not shrivel by vehicle weight, improve the robustness of tire.
Accompanying drawing explanation
Fig. 1 is the radial cross-section of the utility model run-flat tire, generally shows crown zone, shoulder area, sidewall district and bead region part.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present utility model is described in detail.
As shown in Figure 1, described run-flat tire comprises carcass 1, carcass comprises crown zone 11, shoulder area 12, sidewall district 13 and bead region 14, wherein shoulder area is for connecting crown zone and sidewall district, carcass cord carcass plies 15 is provided with in carcass, be embedded with steel bead wire 16 in bead region, after carcass cord carcass plies walks around steel bead wire bottom reversed, its external end head radially upwards extends one section.
In order to strengthen the mechanical mechanism intensity in sidewall district 13, need to increase supporting construction, in the present embodiment, supporting construction is made up of three parts, and the first strengthens rubber layer 131, this reinforcement rubber layer is arranged on inside the district of sidewall, and is crescent shape along the cross sectional shape of tire radial direction.
Its two be positioned at sidewall district skin circumference reinforcement 132 and internal layer circumference reinforcement 133, this outer circumferential reinforcement and internal layer circumference reinforcement are separately positioned on the both sides of the carcass cord carcass plies being positioned at sidewall district, this outer circumferential reinforcement and internal layer circumference reinforcement contiguous mutually and almost parallel, and be filled with sizing material in space between the two, come in contact for avoiding both.The horizontally-arranged width that the circumferential reinforcement of described skin and internal layer circumference reinforcement are formed covers sidewall district overall with, can increase structural strength to greatest extent.Adopt two-layer circumferential reinforcement can optimize the mechanical characteristics, particularly peripherical rigidity in sidewall district further.
It three is the radial reinforcements 134 being positioned at sidewall district, radially distributes substantially, and is arranged in tire both sides along each sidewall, but do not cover whole crown.
In the present embodiment, outer circumferential reinforcement, internal layer circumference reinforcement and radial reinforcement all adopt annular cord.
The above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
Claims (5)
1. a run-flat tire, comprise carcass, carcass is divided into crown zone, shoulder area, sidewall district and bead region, carcass cord carcass plies is provided with in carcass, bead region has the steel bead wire buried underground wherein, after carcass cord carcass plies walks around steel bead wire bottom reversed, its external end head radially upwards extends one section, the cross sectional shape be provided with inside the district of described sidewall along tire radial direction is the reinforcement rubber layer of crescent shape, it is characterized in that, the both sides being positioned at the carcass cord carcass plies in described sidewall district are respectively arranged with outer circumferential reinforcement and internal layer circumference reinforcement, this outer circumferential reinforcement and internal layer circumference reinforcement contiguous mutually and almost parallel.
