Abstract
The utility model provides a novel tread rubber, which comprises a tread rubber body, and is characterized by comprising a tire top, a tire shoulder and a local tire sidewall. The tread rubber has radial radian matching with a tire polished completely, and both the inner sides of the tire shoulder and the tire sidewall have radian matching with the tire shoulder and a tire sidewall shaft which are completely polished.
Description
Technical field
The utility model relates to the tyre retreading technique field, particularly relates to a kind of novel tread rubber.
Background technology
At present, along with developing of automobile industry, the consumption of tire is also increasing, the renovation of old tire utilizes attention and the development that more and more obtains people again, still, and in the present tyre retreading technique, because the restriction of tread rubber, its quality of the tire of renovation and range of application all have been subjected to very big restriction.
Tyre rebuilding mainly contains three kinds of methods both at home and abroad at present:
A kind of is archetype method; Second kind is the heat posted method, and by the model extrusion forming, and heat posted is on the intact carcass of reconditioning with tread mix; The third is the presulfurization method, and tread mix is by model prevulcanization moulding, and binding face polishing back is fitted on the complete carcass of reconditioning with middle pad glue.
Wherein heat posted method and presulfurization method all adopt the strip tread rubber of vulcanizing press sulfidization molding, binding face is the plane, when this tread rubber was fitted in the complete carcass top of reconditioning, radiating groove must adopt rubber to fill up and carries out sulfidization molding between both sides tire shoulder and the sidewall.
This applying vulcanization has following defective: 1. tread rubber with fill up the rubber junction since rise and fall frequent, the bonding force situation is poor, tire is in the motion of travelling, the junction is pushed easy deformation repeatedly, causes and comes unglued; 2. it is bonding that the plane tread rubber only is confined to the tire top, and bond area is little, and intensity descends, and when tyre in operation produced centrifugal force, the glue face easily came off, and influences the performance and the life-span of retreads; 3. the plane tread rubber does not have radiating groove, causes the heat dispersion of tire to descend, and influences tire service life; 4. use rubber to fill up radiating groove, can increase the consumption of sizing material, increase machining period, improve processing cost, and influence the appearance of tire, be unfavorable for applying of this technology, above defective is in the retrofit application of large off-the-road (OTR) tire, and its unfavorable effect and influence are more remarkable.
And existing strip plane tread rubber is when fitting, and the top of tread rubber is forced to depress with the complete tire top of reconditioning by pinch roller and fitted to form new tyre surface, and this tread rubber laminating type can cause the bonding place to have bigger stress; Such tread rubber produces bubble easily on binding face when fitting, can cause tread rubber to come unstuck in the tire use, and cause scrapping of tire, causes potential safety hazard for travelling of automobile.
The utility model content
Defective and deficiency at existing tread rubber existence, the purpose of this utility model is to provide a kind of novel tread rubber, utilizes tread rubber of the present utility model, can increase the bond area of tread rubber and carcass, improve bonding strength, and improve the quality and the appearance of tyre rebuilding.
The technical solution of the utility model is as follows:
A kind of novel tread rubber, comprise tread rubber itself, it is characterized in that: described tread rubber comprises tire top, tire shoulder and local sidewall, described tread rubber has with reconditioning the radially radian that the tire after complete is complementary, and described tire shoulder and inboard, sidewall all have the radian that axially is complementary with complete rear tyre tire shoulder of reconditioning and sidewall.
The inboard tire top radian that is connected with both sides tire shoulder radian that also includes in described tread rubber tire top, the radian on the complete rear tyre tire of described tire top radian and reconditioning top is complementary.
Described tire top radially radian is a radian to the bending of tread rubber coating surface.
The both sides tire shoulder and the sidewall of described tread rubber have symmetrical arcuate structure.
Described tread rubber is and the suitable engineering tyre tread rubber of engineering tyre.
The arranged outside of described tread rubber has radiating groove.
Described radiating groove is distributed on tire top, tire shoulder and the part sidewall of tread rubber.
Described tread rubber outer surface is provided with concavo-convex alternate decorative pattern.
Technique effect of the present utility model is:
The tire shoulder place, both sides of tread rubber of the present utility model has the tire tire shoulder suitable radian structure complete with corresponding reconditioning, when fitting, fit naturally in arc structure and tire tire shoulder position, compare with the tread rubber of existing planar structure, when tread rubber of the present utility model and surface of tyre are fitted, can significantly reduce the stress that tread rubber produces at the tire shoulder place, and increase bond area, improve the quality and the service life of renovation rear tyre, and can significantly improve the security in the retreads use.
Particularly in the retrofit application of engineering tyre, has very big thickness owing to be used for the tread rubber of engineering tyre, therefore it is when fitting, the distortional stress that is produced is also bigger, existing plane tread rubber is in the retrofit application of engineering tyre, owing to radial and axially when tread rubber is fitted all will produce very big stress, adhesive surface only is confined to the tire top, bond area is little, tire after the renovation easily produces the mass defect that the tread rubber applying is not firm, come unstuck, ftracture, not only can cause the service life of tire short, but also be easy to produce accident hazard.
Tread rubber tire of the present utility model top, tire shoulder and part sidewall are provided with radiating groove, can reduce the colloidal materials consumption of tread rubber, improve the heat dispersion and the wear-resisting time of tire, prolong its service life.
In addition, it longitudinally also has certain radian tread rubber of the present utility model, when the carcass with reconditioning after complete is fitted, can reduce the whole stress that produces when bonding with tire of tread rubber, reduce the probability that produces bubble, improve bonding effect and intensity, and the quality of corresponding raising retreads and security feature.
In sum, tread rubber of the present utility model is compared with existing tread rubber, has to fit simple and conveniently, and distortional stress is little, and bond area is big, intensity height, safe and reliable characteristics.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Figure 2 shows that the structural representation of existing plane tread rubber, tread rubber 11 its colloids are originally as a slab construction, and the tread rubber outer surface is provided with recessed decorative pattern.

The inboard on tire top 2 also includes the tire top radian R3 that is connected with both sides tire shoulder radian R1, and the radian on the tire tire top after described tire top radian R3 and reconditioning are complete is complementary.
In the present embodiment, the tire top 2 of tread rubber 1 and tire shoulder 3 and part sidewall outer surface are provided with radiating groove 5, radiating groove 5 can reduce the required colloid consumption of raw materials of preparation prevulcanized tire tread rubber on the one hand, on the other hand, can improve the heat dispersion of tire in the use, improve the serviceability and the life-span of tire.
Certainly, the structure of radiating groove 5 can be other shape, the shape that is not limited in the present embodiment to be put down in writing.
The above only is a preferred implementation of the present utility model, and foundation essence of the present utility model can also be made other distortion and improvement, but these distortion and improvement all will fall into protection domain of the present utility model.
