Description
Technical field
A meridian line tyre is the utility model is related to, more particularly, to a kind of full zero degree tire with steel belt.
Background technology
The cord of meridian tyre body is arranged differently than cross-ply, and the cord of radial is not the row of intersecting
Row, but with cover tire section close to parallel, as terrestrial meridian arranges, cord angle is small, is generally 0 ° or is close to zero degree,
Intersection point is not maintained between body cord, when tire in the process of moving, bizet ambient stress increase, circumferential extension can be caused,
Carcass radial breach.Therefore the cushion of radial uses the cord ply of coming into contacts with close to circumferential array, with carcass
Cord angle is in 90 ° intersecting, generally 70 ° to 78 °, a rigid annular shaped band that can hardly be upheld is formed, whole tire
It is fixed, the circumferential deformation of tire is limited, this cushion bears the internal stress of whole tire 60% to 70%, becomes radial
Main stressed member, therefore the referred to as belt of radial.The main stressed member of bias tire not on the buffer layer, its
80% to 90% internal stress undertakes by the casing ply of carcass.It can be seen from the above that radial tire undertread design is critically important, it is necessary to
With good rigidity, multilayer wide-angle, high intensity and not easily stretchable fibrous material can be used, as steel wire or aramid fiber are fine
Dimension etc..
But the belt of existing radial is generally arranged on two side positions of corresponding tyre surface, middle part is equipped with non-zero-degree
（Or the non-cushion close to zero degree）So that it in sulfidation, colloid has enough abilities outwards expanded, so as to reach
The requirement formed to tread.This allow for the tyre surface of this meridian line tyre middle part be still easily deformed.
The content of the invention
The utility model be mainly solve present in the prior art in order to adapt to existing technique, and cause rotating radial
The zero-degree belt of tire is only arranged on the position of the both sides of corresponding tyre surface, so that the structure in the middle part of its tyre surface is not sufficiently stable, and
The technical problem being easily deformed, there is provided a kind of full zero-degree belt, stable structure, the not on-deformable radial of tyre surface.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：A kind of full zero degree steel
Silk braced tyre, including casing ply, belt and crown, it is characterised in that the casing ply is metal-cord or change
Fine casing ply, the belt are one chip, and arranged on the middle part of tyre surface, transition zone, institute are equipped between belt and casing ply
The all-steel cord for the belt stated is one to three cords, and non-overlapping copies also do not intersect, and band is arranged in the form of spiral winding
In the colloid of beam layer, the angle of the all-steel cord and the equatorial line of carcass circumference is less than 3 degree.
It is overall a piece of that the one chip of belt refers to that every layer of belt only has, arranged on the center of tyre surface, it relative to
Existing belt, every layer of tire for being equipped with symmetrical two panels belt, the technical program cause tire overall all in nullity belt
In the parcel of beam layer, the highly stable carcass strength of overall structure is very big.The angle of all-steel cord and the equatorial line of carcass circumference is small
In 3 degree, this is the technological requirement of zero-degree belt, and band is made by the way of one to three cord spiral windings in the utility model
Beam layer, carcass is acted on good banding, its angle is entirely zero degree close to zero degree, but not, has a small angle
The error of degree, in technique, can accomplish less than 3 degree, and in actual use, the error of this low-angle completely can be with
Receive.The setting of the filter layer of the utility model so that with cord into that will not contact, both steel wires would not make belt
The problem of directly being rubbed with middle appearance, being disconnected from the steel wire without being formed by the friction of both steel wires.
Preferably, the transition zone is equipped with nylon cord.Transition zone sets nylon cord so that its with casing ply and
Friction between the all-steel cord of belt will not cause all-steel cord wear and rupture.
The production method of the utility model, includes the following steps：
1）Casing ply is manufactured, forms the basic configuration of carcass；
2）Transition zone is set outside casing ply；
3）The belt is set outside transition zone；
4）Crown layer is manufactured, it includes the following steps,
I takes the sheet colloid of proper width, by finishing die, is allowed to be formed the ditch body of strip, which is tread
Zanjon part, that is, form the prefabricated colloid of crown layer,
The prefabricated colloid of crown layer is arranged on the outside of belt by II；
5）Tire is put into vulcanizing mold and is vulcanized, at high temperature under high pressure, the shallow ridges part of tread is formed, in the vulcanization
During, zanjon part can produce lateral deformation, ultimately form complete tread with the shape according to mould.
The structure of the full zero degree steel belt of the utility model so that the stability of carcass is very good, but also causes it
Due to that cannot make it that tyre surface is that lines can not be effectively formed to external expansion in sulfidation, in order to solve the problems, such as this, this
The zanjon part of the first prefabricated tread of utility model, can substantially eliminate that grinding tool internal diameter is small and the weight of tire base outside diameter greatly between the two
It is folded, tire base is smoothly molded with mould.In sulfidation, as long as the minimum outside stretching exercise of all-steel cord and rubber
The flowing of glue in itself can just make tyre surface form shallow ridges part, so as to form complete tread.
The beneficial effect brought of the utility model is, solve present in the prior art in order to adapt to existing technique,
And make it that the zero-degree belt of radial is only arranged on the position of the both sides of corresponding tyre surface, so that the knot in the middle part of its tyre surface
Structure is not sufficiently stable, and the technical problem being easily deformed, there is provided a kind of full zero-degree belt, stable structure, not tyre surface be unlikely to deform
Radial, also by the prefabricated of tread zanjon part so that the structure of the utility model is achieved.
