Description
Technical field
The present invention relates to a kind of tire, especially relate to a kind of motor tire and production technology thereof.
Background technology
The keystone configuration characteristics of existing radial-ply tyre have following some:
1. each interlayer of body cord is the meridian direction arrangement by a tyre bead to another tyre bead.Inner pressure of tire is few half the to the common diagonal tyre of stress amplitude ratio that body cord produces, and all cords fabric thread are according to being arranged by force direction, and every cord is fully stressed;
2. radial tire undertread is main stressed member, bears the 60-75% of the total expansion force of inner pressure of tire;
3. because the body cord meridian is arranged, can bring into play the cord strength effect to greatest extent, but the carcass sidepiece lacks softness because of the number of plies and rigidity is not enough, the normal direction distortion increases 25-30% than diagonal tyre, and the distortion of position, sidewall is big, pierces through easily.
In order to improve the firmness of carcass, people often need make the carcass of bilayer or multilayer cord, when cord is steel cord; In the use, meeting phase mutual friction between its two-layer curtain is owing to only covered the very thin glue-line of one deck on the steel cord; In the cord phase of two interlayers after mutual friction a period of time, will inevitably occur that glue-line on the steel cord is worn, the consequence of double-ply steel cord direct friction, at this moment; Wearing and tearing significantly can appear in steel cord; Cause its insufficient strength, problem such as do not plan a successor between the two-layer carcass plies has a strong impact on the quality of carcass.
According to the characteristics of above-mentioned radial-ply tyre, bracing ply is the topmost part of the force of radial-ply tyre, and it is determining the distortion of carcass to a great extent.Directly have influence on the rigidity of tyre surface, so it is to the resistance to abrasion of tire, riding stability, traveling comfort etc. has material impact.
Theoretically, belt cord angle (with the angle of tire equator) is more little, and good more to the banding effect of carcass, the rigidity of tyre surface is strong more.But because in the existing production technology, cord angle is too small, not only make the technological operations such as severing and joint of bracing ply complicated, and unfavorable to the tire in-use performance, be easy to generate the danger of bracing ply delamination.So existing belt cord is general and tire circumferentially is 15-20 degree angle.But the rigidity of this meridian line tyre has still received very big restriction, and general bracing ply will adopt the structure than multilayer to remedy the defective on its rigidity.This had just both increased cost, had also increased the weight of tire simultaneously, and this has just received very big restriction at lilliput car aspect the use of radial-ply tyre.
In order to reduce the distortion of bracing ply shoulder, improve the tire shoulder rigidity of radial-ply tyre, reduce distortion and give birth to heat, the protection bracing ply is avoided the fatigue damage that the ess-strain effect produces.Guarantee when running at high speed, to have stable size; Improve tyre surface stability, reduce irregular wear; Italy Pirelli company has designed a kind of radial-ply tyre of zero degree belt structure, and it is provided with at two shoulders of bracing ply and two-layerly twines the annular reinforcing bundle bar that two circles form along circumferential array is overlapping.It is compared with ordinary construction bracing ply radial-ply tyre has reduction rolling resistance, fuel saving; Low-heat-generation falls, tyres durable safety, and tyre surface is stable, improves the advantages such as lateral rigidity of tire.But this design improves the complexity of technology, be with cost rise to cost more greatly, and; The rigidity in the centre of bracing ply does not effectively improve, even because the rigidity of its both sides bracing ply is excessive, and the rigidity at middle part is less; In the middle of the high pressure sulfuration of tire; The carcass both sides can not upheld, and the middle part produces bigger extension, cause the tire deformity.In order to solve above-mentioned these problems; My company has designed a kind of " radial-ply tyre of zero degree bracing ply " (being the radial-ply tyre of angle between the 0-15 degree of belt cord and tire equator), and the bracing ply of this meridian line tyre adopts the mode of single or some steel cord coiled coils.In order to satisfy the production needs of this bracing ply; We have retrieved the related process device; Publication number is that the Chinese utility model of CN2471524 discloses the multiple rubber extruding machine of steel wire bracing ply, it by steel cord spindle frame, extrude multiple adhesive dispenser, cooling draw gear, severing piecing devices, Wrapping apparatus and double batch up gear and constitute.The advantage of this utility model is the production process that bracing ply disperses is step by step concentrated in together, but can't satisfy the production demand of the helical structure bracing ply of " radial-ply tyre of zero degree bracing ply ".Publication number be the Chinese patent of the CN1615229 Pneumatic belt tire that discloses a kind of construction vehhicle with and the manufacturing approach of bracing ply and this tire; Wherein use the cord bundle to constitute its width and be the one deck at least in the 0.25-0.5 bracing ply doubly of tread width; Each cord bundle is formed with the steel cord that about equally interval is arranged parallel to each other by multistage; Make distance between near the steel cord cord bundle and its greater than those distances between the intrafascicular steel cord of cord; Steel cord is set to 0-15 ° with respect to the angle of cut of the equatorial plane of tire, and the diameter of steel cord is set in the scope of 1.0-6.0mm, and forms the cord bundle in the following manner; Promptly; Apply the cord that forms the cord bundle thinly with rubber layer after, make these cords pass insert, can prevent separation thus, thereby improve the bracing ply durability in place, the end appearance of steel cord with coating rubber integrally.Above-mentioned 0-degree belt is because it is stable in the circumferential shape of tire; Even in the high pressure curing process, can not stretch yet, therefore, after its sulfuration; Bracing ply forms column construction; And in the use of tire, the stress of its two shoulder is comparatively concentrated, wearing and tearing are bigger, occurs the situation that bracing ply both sides colloid splits, cord exposes easily.In diagonal construction tire, bracing ply can be because uphold at the middle part in curing process, and its cross section can produce an arc; Be the structure of median rise, make bracing ply both sides colloid be difficult for splitting shape, but in zero belted-layer tires; Because the rigidity of bracing ply is bigger, in the curing process, its each position can be upheld hardly; Therefore, in the prior art, the precedent that does not also address this problem.
