Abstract
The utility model discloses a ring tyre tread for retreading tyres, which belongs to the technical field of tyre retreading. The utility model is characterized in that the whole body of the ring tyre tread is a closed circular ring, the external surface of the ring tyre tread is provided with antiskid design, and the shape of the internal surface is matched with the shape of a ground junked tyre tread. The ring tyre tread is composed of a tyre tread adhesive layer 1, a framework material layer 2 and a buffer layer 3 which are arranged successively from inside to outside. The ring tyre tread overcomes the defect of easy tackless generation of the joint of bar-shaped tyre treads and improves the reliability and service life of a retreated tyre. The utility model is used for the retreading industry of tyres.
Description
The utility model relates to a kind of tyre rebuilding annular tire tread.
Current, tyre industry all adopts traditional method and presulfurization strip tyre soles process technology, because traditional method production technology is backward, and retreads degumming rate height, service life is short, so this process progressively is being eliminated.Presulfurization strip tyre soles process technology is the most popular in the world in recent years, and the more existing enterprises of China have introduced this technology.The tire long service life of this technology renovation, but because the strip tyre surface always has joint on tire, the joint phenomenon of coming unglued happens occasionally, and to old tire quality requirement harshness, incompatibility oblique tire and giant tire renovation, production cost height.
The purpose of this utility model just provides a kind of novel retreads material-annular tire tread that can increase substantially the reliability and the serviceability of retreads.
Utility model technical essential of the present utility model has adopted outer surface to have anti-skid design, the circular tread of the closure that the old tire after inner surface and the grinding matches.
Below by Figure of description, structure of the present utility model is described in detail: the annular tire tread that a kind of retreads are used, it is characterized in that integral body is the closed round ring shape, its outer surface has various anti-skid designs, and the old tire face after inner surface and the grinding is identical shape.
Annular tire tread described in the utility model can be with pure tread rubber or plastic cement, also can with compound the making of framework material, cord ply compound, buffering adhesive of kiss-coating.In order to improve the bond strength of annular tire tread and carcass, reduce its distortional stress, improve its wearability, so the Cross section Design of annular tire tread is become rectangle, trapezoidal, concentric circles arc, non-concentric circles arc or crescent etc., and supporting with it carcass also should be ground to and the corresponding shape of the inboard corresponding shape of shape of annular tire tread.
Framework material described in the utility model can be with nylon cord, terylene cord fabric, also can be weaving, the braid of metal cord fabric, wire or metallic fiber, mineral fibres, chemical fibre.
Manufacture method of the present utility model is to be main material with the tread rubber, and is compound with framework material, is placed on sulfuration or semi-cure moulding in the sulfurizing mould, also can adopt the plastic material injection mo(u)lding.Annular tire tread is sleeved on the old tire after the grinding carries out post-cure or bonding, promptly finished the renovation of tire.
Because tire is an elastomer, its elasticity of the tire that different structure or different materials are made has very big difference, in order to make firm bonding of annular tire tread and carcass, annular tire tread produces a prestressing force to carcass, tightly act on the carcass, and carcass produced strengthening action, the annular tire tread of selection different inner diameters that will be corresponding cooperates with carcass, the internal diameter of the described annular tire tread of Fig. 1 can less than or greater than the diameter of carcass behind the skiving.
The outer surface of tread rubber 1 can be designed to have various anti-skid designs in the described annular tire tread cross section structure of Fig. 1 layer, and its side can have colors such as indigo plant, green, Huang.Promptly retreads can be obviously distinguished, purpose attractive in appearance can be reached again; Tread rubber 1 is bonded as one with the framework material layer 2 of kiss-coating, and framework material layer 2 improves the intensity of annular tire tread, can make tire obtain reinforcement, and framework material can be the meridian wire or be the strong inboard one side that is arranged near annular tire tread of oblique; Cushion gum layer 3 can play in tire running the effect of buffering and dispersive stress, and helps combining with rubber.When carcass strength is big, can use tread rubber 1 or tread rubber 1 and buffering adhesive 3 separately.But no matter adopting arbitrary combining form, must be material of main part with the tread rubber all.
The various cross sectional shapes of annular tire tread that Fig. 3～Fig. 7 describes can be respectively applied for radial, cross-ply, flat tire and heavy construction vehicle tyre etc.Consider the factors such as structure, abrasion condition and load of various tires, save tread rubber as much as possible, reduce the cost of annular tire tread, improve the service life of annular tire tread, the cross sectional shape of reasonably selecting annular tire tread is very important.
In order to improve the intensity of annular tire tread, utilize different shrinkage factors and the tension force and the adjusting process parameter of different materials in its structure sheaf, can make its inner prestressing force that produces, promptly the annular tire tread outer surface has compression, and there is a tension inboard.
Since the defective that annular tire tread has avoided joint to come unglued, and add framework material as required, and make it have prestressing force, and improved the performance of retreads effectively, improved the reliability and the service life of retreads greatly.
Fig. 1 is an organigram of the present utility model;
Fig. 2 is an annular tire tread shown in Figure 1 square-section schematic diagram;
Fig. 3 is an annular tire tread shown in Figure 1 trapezoid cross section schematic diagram;

In the above accompanying drawing: 1 tread band, 2 framework material layers, 3 cushion gum layer.
Among the embodiment of the present utility model, annular tire tread is from being made of tread band 1, framework material layer 2 and cushion 3 successively outside to inside.
Among another embodiment of the present utility model, annular tire tread is from being made of tread band 1,2 on framework material layer successively outside to inside.
Among the 3rd embodiment of the present utility model, annular tire tread is from being made of tread band 1, cushion 3 and 2 on framework material layer successively outside to inside.
