Abstract

The utility model discloses a steel wire belt bundle ring-shaped tread that takes the shape of closed ring and consists of a tread glue layer and a framework layer. The framework layer consists of three belt bundle layers and two 0-degree cap ply layers. A first belt bundle layer and a second belt bundle layer arranged inside the ring-shaped tread and arranged outwards sequentially are working layers, a third belt bundle layer is a protective layer and all the layers are arranged crossly. The two 0-degree cap ply layers are above the second belt bundle layer, at two sides of the third belt bundle layer and parallel with the central line of a tire cap. As for a tire that is remanufactured by using the tread, the rigidity of the shoulder of the tire can be improved, the shoulder generates less heat, the belt bundle layer is prevented from fatigue damage and heat damage caused by the strain action of stress, the bearing capability is enhanced and non-uniform abrasion is reduced. The tire manufactured is applicable to intermediate-distance or short-distance large cargo capacity transportation and poor mixed road surfaces. The steel wire belt bundle ring-shaped tread has marked social benefits.

Description

A kind of wire tape beam ring shape tyre surface

Technical field:

The utility model relates to a kind of annular tire tread that full steel wire heavy load radial tire is made again that is used for, and particularly relates to a kind of wire tape beam ring shape tyre surface.

Background technology

At present, increasing along with the full steel wire heavy load radial tire application quantity, be replaced the junked tire that gets off also in continuous increase, this wherein only tread contour polish and carcass is damage-free can use only accounting for about 5% that traditional presulfurization bar shaped tyre surface makes again, and crown bracing ply steel wire is ground with or is impaired, the intact junked tire of value that still has of carcass has then accounted for more than 40%, this part junked tire can not be used the bar shaped tyre surface and make, or be broken and make rubber powder, or by local method burning oil refining, or abandoned is stacked everywhere, rubber sources in short supply is by serious waste, and environment is destroyed by gross pollution; Therefore, improve full steel wire heavy load radial tire manufacturing rate again, carry out the tire resources circulation and utilize again and protect environment imperative.Junked tire is except that adopting bar shaped tyre surface reproducing method, having in the society at present utilizes the decorative pattern of cutting off still to have the old tire jacking row of certain depth to make again, but the old tire top of cutting off exists serious hidden danger, for example no matter the used tire before under the old tire vertex cut is sidewall explosion or tyre bead explosion in use (high speed revolution), the capital makes crown impaired to some extent and phenomenons such as light or heavy delamination or steel wire bracing ply be impaired occur, not in place owing to checking when cutting off old tire top in addition, still existing the bracing ply steel wire may be by problems such as thorn break, and these all seriously affect the safety performance of making tire again.Therefore, old tire top can not be used for tire and makes; A kind of " annular tire tread " that is used for tyre rebuilding disclosed and notification number is the utility model patent of CN2433076Y, the structure of its annular tire tread is from being made of tread band, casing play and cushion layer successively outside to inside, but the description to casing play in its specification sheets is unclear, do not have actual operability, this just makes technical personnel will carry out test repeatedly in implementation process, just can design satisfactory casing play structure by creative work.

Summary of the invention:

The purpose of this utility model is at the deficiencies in the prior art; a kind of wire tape beam ring shape tyre surface is provided; can be used for full steel wire heavy load radial tire makes again; the casing play of its annular tire tread is made up of composite steel silk bracing ply; the strength character that can guarantee to make again tire reaches the requirement of new tire; technical matters to be solved is the arrangement architecture of composite steel silk bracing ply; determine the kind of cord angle and the width and the bracing ply steel cord of every layer of bracing ply; technical solution adopted in the utility model is as follows; the utility model is closed annular shape; by tread band; casing play is formed; the outer ring surface of tread band has and can transmit vehicle tractive force and braking force and with the road surface the good then tread void of performance be arranged; interior ring surface can coincide with the old crown after the polishing; it is characterized in that casing play is made up of three layers of bracing ply and two layers of 0 ° of band; be positioned at outside successively ground floor in annular tire tread inboard and second layer bracing ply working lining for making by high strength or ordinary steel wire cord; and cross arrangement; the cord angle of ground floor bracing ply is 64～74 °; the cord angle of second layer bracing ply is 73～83 °; the 3rd layer of bracing ply high extension or protective cover that the ordinary steel wire cord is made of serving as reasons; cord angle is 73～83 °; and with the cross arrangement of second layer bracing ply; the width of ground floor bracing ply is narrower than second layer bracing ply width; the 3rd layer width is the narrowest; the wideest bracing ply width is 70～85% of a tread surface width; two layers of 0 ° of band are on second layer bracing ply; be positioned at the 3rd layer of bracing ply both sides; and parallel with the crown line of centers, make by height extension or ordinary steel wire cord.

The width of above-mentioned ground floor, the second layer, the 3rd layer of bracing ply also can narrow down successively.

Compared with prior art; the tire that uses the utility model to make again; can improve the rigidity of tire shoulder; reduce the tire shoulder and give birth to heat; the protection bracing ply is avoided fatigue damage and the heat damage by ess-strain effect generation, improves tyre capacity, reduces irregular wear; be fit to short-distance big cargo capacity transportation and use obvious social benefit on relatively poor mixing road surface.

The specific embodiment:

The utility model is closed annular shape; by tread band; casing play is formed; the tread band of outer shroud has can be transmitted vehicle tractive force and braking force and with the road surface the good then tread void of performance be arranged; interior ring surface can coincide with the old crown after the polishing; casing play is by three layers of bracing ply 1; 2; 3 and two layers of 0 ° of band 4 are formed; be positioned at outside successively ground floor in annular tire tread inboard and second layer bracing ply 1; 2 is working lining; and cross arrangement; the cord angle of ground floor is 64～74 °; the cord angle of the second layer is 73～83 °; the 3rd layer of bracing ply 3 is protective cover; cord angle is 73～83 °; and with the cross arrangement of second layer bracing ply; the width of ground floor bracing ply is narrower than second layer bracing ply width, and the 3rd layer width is the narrowest, and the wideest bracing ply width is 70～85% of an annular tire tread tread width; two layers of 0 ° of band are on second layer bracing ply; be positioned at the 3rd layer of bracing ply both sides, and parallel with the crown line of centers.

As shown in Figure 3; on the transversal surface of wire tape beam ring shape tyre surface; the outer ring portion of tyre surface is a tread-rubber 5; tread-rubber is to have with the road surface the vertical of good then performance arranged; laterally or the wear-resisting tyre surface of groove such as mixing; can transmit vehicle tractive force and braking force; ground floor bracing ply 1 and second layer bracing ply 2 are made by high strength or ordinary steel wire cord; mainly bear inflation stress; playing a part the constraint carcass outwards expands; the 3rd layer of bracing ply 3 is protective cover; make by height extension or ordinary steel wire cord; can play buffering and impact and protect the purpose of working lining from ground-surface; on second layer bracing ply; be positioned at the 3rd layer of bracing ply both sides; and continuous winding double-ply 0 ° band 4 parallel with the crown line of centers; make by height extension or ordinary steel wire cord, can reduce the distortion of bracing ply limit portion, improve the rigidity of tire.
