Description

Full-through tread primer structure of load radial tire

Technical Field

The utility model belongs to the technical field of the tire is made, concretely relates to load radial tire link up tread primer structure entirely.

Background

The quality of the tire, which is an important component of a vehicle, directly affects whether the vehicle can be used normally and the safety of the vehicle during running. The heavy-duty radial tire is a common tire on a heavy-duty vehicle, and mainly comprises a tire bead, a tire side, a tire shoulder and a tire crown from the appearance structure, and mainly comprises an air-tight layer, a tire body, a cord fabric layer, a belt ply, a tire tread and the like from the internal dissection layering. In the production process of the tire, crown rubber is generally arranged between a tire tread and a belted layer, wing rubber is arranged at tire shoulders on two sides of the crown rubber respectively, (as shown in figure 1) the existing crown rubber is directly attached to the belted layer, mechanical energy of tire deformation is converted into heat energy in the driving process of a vehicle, a large amount of heat can be generated on the belted layer, the tire can generate obvious heating phenomena, particularly the tire generates heat seriously when a heavy-duty vehicle runs for a long distance, the tire generates heat to accelerate tire aging, the performance of sizing materials is reduced after long-time use, meanwhile, the adhesive force of the sizing materials and steel cords is reduced, belted separation is generated, the durability of the tire is very unfavorable, even the tire tread and the crown rubber, the belted layer and the wing rubber are separated, the wing rubber is extruded and displaced, so that a side wall is bulged, the service life and the safety performance of the tire are seriously influenced, and great potential safety hazards are brought to the vehicle.

SUMMERY OF THE UTILITY MODEL

To the above situation, the utility model provides a load radial tire link up tread primer structure entirely can improve the tire ageing problem that the tire generates heat and leads to, prolongs the life of tire.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a load radial tire link up tread base rubber structure entirely, glues including the hat, the both sides lower part is glued to the hat sets up the wing respectively and glues, be provided with under the hat glues and connect gluey, glue through connecting between the two wings and link up the connection and be a whole, two wings glue and connect gluey downside to cover and have the one deck dustproof membrane that can tear down.

Further, two the connection face that wing glue and hat were glued is the arcwall face of epirelief, compares in the trapezoidal or triangular connection face of traditional wing glue, and the area of connection of arcwall face is bigger relatively, and low themogenesis material area is also bigger, and wing glue bending nature is also better, and the durability is also better.

Furthermore, the dustproof film is a flexible plastic film and is mainly used for preventing dust from being stuck to the bottom of the rubber surface, and the dustproof film is torn off in the tire manufacturing process, so that the crown rubber can be conveniently adhered and laid.

Furthermore, wing glue and connection are the low themogenesis rubber preparation, have fine low heat buildup nature, can improve the durability of tire to have certain viscoelasticity, help the dust mask to adsorb, also be convenient for simultaneously the dust mask tears down.

Furthermore, the wing glue, the connecting glue and the crown glue are integrally co-extruded and formed.

The utility model discloses still including other subassemblies that can make its normal use, be the conventional means in this field, in addition, the utility model discloses in add the device or the subassembly of injecing, all adopt the prior art in this field.

The utility model has the advantages as follows:

the utility model provides a pair of load radial tire link up tread base rubber structure entirely, glue two wing glues through connection of both sides with the hat and be a whole, prevent that wing glue from extruding the aversion, the whole low themogenesis rubber preparation that adopts of wing glue, form the protection protective screen between hat glue and belted layer, can show the tire ageing problem that the improvement tire generated heat and caused, extension tire life reduces vehicle safety hidden danger.

Drawings

Fig. 1 is a schematic structural diagram of a prior art crown rubber in the background art.

FIG. 2 is a schematic view of a fully through tread base rubber structure of a heavy duty radial tire in an embodiment.

In the figure: 1. crown gum; 2. wing glue; 3. connecting glue; 4. and (5) a dustproof film.

Detailed Description

The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments, and it should be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.

Examples

As shown in figure 2, a full through tread base rubber structure of load radial tire, glue 1 including the hat, the both sides lower part is glued to the hat sets up wing glue 2 respectively, be provided with under the hat glue and connect gluey 3, glue through connecting to glue through-connection between the both wings and be a whole, two wing glue is the arcwall face of epirelief with the face of being connected that the hat glues, and both wings glue and connect gluey downside to cover and have one deck dust-proof membrane 4 that can tear down.

The dustproof film is a flexible plastic film with the thickness of 0.1mm, when the tire is manufactured, the dustproof film is torn down, the whole crown rubber is conveniently bonded and laid, and the maximum thickness of the middle part of the crown rubber is 22mm.

The wing rubber and the connecting rubber are both made of low heat generation rubber, the thickness of the connecting rubber is 3mm, the maximum thickness of the arc wing rubber is 9mm, the low heat generation rubber is made of known materials which are the same as the low heat generation rubber composition disclosed in the invention patent CN109749146B, and details are not repeated here.

And the wing glue, the connecting glue and the crown glue are integrally co-extruded and formed, and all parts of the crown glue are co-extruded and processed by a co-extruder through an extrusion die with a specific shape.

The technical solution of the present invention is not limited to the above-mentioned specific embodiments, and many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
