Description
Technical field
The utility model relates to tire and manufactures field, especially a kind of all-steel engineering radial-ply tyre of the nullity belt structure with protective cover.
Background technology
In recent years, small engineering machinery development both at home and abroad increases very fast, the fast development of especially domestic mine wide dumper, and this has just proposed tire and has met the demand using under complex road condition condition.Compared with oblique engineering tire, full steel wire meridian engineering tyre is because crown structure is simpler, use road conditions harshness, load high, often because the reason damage bracing ply such as sharp objects puncture, cutting on road surface, and final the phenomenons such as hat is quick-fried occurs.
The crown belt structure of full steel wire meridian engineering tyre is common three kinds of structures such as zero-degree belt, quadriply belt bundle layer (Fig. 3 and Fig. 4) and five layers of bracing ply.Adopt the tire of existing belt structure in use, due to track harshness, as the severe metal mine such as iron ore, manganese ore, gold mine road surface, the load that tire bears is larger, and moving velocity is very fast, the ram ratio that crown is subject to is larger, tread mix is easily wounded by stabbing or is pierced through, and causes steel belt exposed, exposed steel wire under the erosion of steam by corrosion after strength decreased, lose the tightening force to tire carcass, the final quick-fried phenomenon of hat that occurs.
Summary of the invention
The purpose of this utility model is: the all-steel engineering radial-ply tyre that a kind of nullity belt structure with protective cover is provided; its implementation cost is lower; can effectively meet the condition of high load capacity, certain speed performance; and can solve the problems such as the hat causing after tire is wounded by stabbing is quick-fried; significantly improve the anti-puncture of crown of full-steel radial ply mini engineering tire, the quick-fried ability of anti-hat and service life, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of all-steel engineering radial-ply tyre of the nullity belt structure with protective cover, be included in carcass ply and be arranged on the bracing ply member on carcass ply, it is characterized in that: the 1# bracing ply of bracing ply member is directly fitted on carcass ply; On 1# bracing ply, be fitted with 2# bracing ply; On 2# bracing ply, be fitted with 3# bracing ply; Above the 2# bracing ply of the both sides of 3# bracing ply, be provided with symmetrical zero-degree belt, on 3# bracing ply, be fitted with protective cover bracing ply.
Described 1# bracing ply is made by rolling steel wire cord fabric cutting, and the circumferential angle angle of steel wire and tire is 15～90 °.
Described 2# bracing ply is made by rolling steel wire cord fabric cutting, and the circumferential angle angle of steel wire and tire is 15～90 °.
Described 3# bracing ply is made by rolling steel wire cord fabric cutting, and the circumferential angle angle of steel wire and tire is 15～90 °.
Described zero-degree belt is made up of high-elongation calendering steel wire cord fabric cutting, circumferentially fits 2 weeks along tire, and the circumferential angle of steel wire and tire is 0 °.
Described protective cover bracing ply is made by rolling steel wire cord fabric cutting, and the circumferential angle angle of steel wire and tire is 15～90 °, and the two ends of protective cover bracing ply cover on zero-degree belt or are only fitted on 3# bracing ply, do not cover zero-degree belt; If protective cover bracing ply covers on zero-degree belt, the outer end stand out level of the outer end of protective cover bracing ply and zero-degree belt is 4～20mm.
The width of described 2# bracing ply is greater than the width of 1# bracing ply, and the stand out level at 1# bracing ply and 2# bracing ply two ends is 8～25mm; The width of 2# bracing ply is greater than the width of 3# bracing ply, and the stand out level at 2# bracing ply and 3# bracing ply two ends is 8～25mm.
Owing to having adopted technique scheme; compared with prior art; the utility model increases the protection bracing ply of bizet and the zero-degree belt of shoulder on the basis of traditional zero-degree belt and quadriply belt bundle layer structure; guarantee the bizet intensity under high load conditions, and speed ability under high load conditions.Protection bracing ply cover 3# bracing ply and or zero-degree belt; zero-degree belt steel wire or 2# bracing ply steel wire and 3# bracing ply steel wire are exposed out directly to be contacted with air or steam being subject to also can not allow after wound puncture to make tire tread compound; angled protection bracing ply additionally provides certain constraint ability, has ensured that the load-carrying properties of this tire are higher than adopting the tire load-carrying properties of common four layers of structure of steel wire bracing ply or normal zero-degree belt.In practice of construction design process, the severing of protective cover, forming process technique and normal bracing ply severing, forming process technique are the same, only need existing moulding feeder apparatus to do easy improvement.The utility model novel structure, result of use is good.
