Abstract
The utility model provides a belted layer of an all-steel radial truck tire, which comprises rubber and a plurality of core strands positioned in the rubber, wherein each core strand of the belted layer consists of three monofilaments in the middle and nine monofilaments which are evenly positioned around the three monofilaments, the density of the core strands in the rubber is 60 core strands/10 cm, cord threads without outer wire winding of a tire is formed by the plurality of core strands in the rubber, and the monofilaments are in line contact with one another and concurrently twisted. The belted layer has the beneficial effects that (1) the cord threads have no wire winding, and the monofilaments are in line contact with one another, so as to reduce the wear among the monofilaments, and improve the fatigue resistance of the steel cord threads; (2) the monofilaments are concurrently twisted, so as to avoid cutting of cord threads when the belted layer is used; (3) the steel cord threads have higher strength, so that the safety performance of the tire is improved; and (4) the steel cord threads have smaller diameters, and large wire reeling length, so as to reduce the thickness of rolling cord fabric, improve the production efficiency and tire quality, and save the production cost.
Description
Technical field
The utility model relates to doughnut, specifically a kind of band bundled layer of all steel load radial line tire.
Background technology
Along with auto industry and Freeway Development, China's all steel load radial line tire production has been stepped into a fast-developing period, and the requirements such as security, comfortableness and economy of tire are also being improved constantly, each giant tyre company is all considering how to develop, production high-performance, tire cheaply are to improve himself competitiveness in market.
All steel load radial line tire sidewall is relatively weak, and carcass steel cord subject to damage, this product are mainly used in first band bundled layer of all steel load radial line tire on the carcass of 11R22.5,11R24.5 carcass.In the prior art, the used steel cord of first band bundled layer is 3+9 * 0.22+0.15 all-steel cord, is characterized in decoring outside the thigh, filament diameter is little, for the some contact, is multilayer ordinary lay structure between the monofilament, in distortion, easily cause the wearing and tearing between the monofilament, the intensity of cord is reduced, influence the security performance of tire, complex structure, strike-through poor performance, processing technology complexity, the cost height, line density is big, be applied to tire after, tire weight is bigger, and the service life of tire is short.
Summary of the invention
In order to overcome above-mentioned defective of the prior art, the utility model provides a kind of band bundled layer of novel all steel load radial line tire, with simplified processing process, improve the tire overall performance, improve tire endurance, anti-bend around and abrasion resistance properties, reduce the tire production cost, prolong tire service life.
To achieve these goals, the technical solution of the utility model is: the band bundled layer of all steel load radial line tire, comprise rubber and be positioned at some core thighs of rubber, it is characterized in that: the core thigh of this band bundled layer is made up of three monofilament in the middle of being positioned at and 9 monofilament that are positioned at uniformly around these three monofilament.
Further, the density of core thigh in rubber is per 10 centimetres 60, and some core thighs in rubber constitute the cord of tires, and described cord has and do not twine silk outward, for line contacts, is twisting in the same way between the monofilament between the monofilament.
The beneficial effects of the utility model are: (1) cord does not have the silk of winding, for the line contact, has reduced the wearing and tearing between the monofilament between the monofilament, has improved the fatigue performance of all-steel cord; (2) be twisting in the same way between the monofilament, can avoid the cord cutting in the use; (3) all-steel cord intensity is bigger, has improved the security performance of tire; (4) the all-steel cord diameter is more less, and take-up length is bigger, can reduce to roll cord thickness, enhances productivity, and reduces tire quality simultaneously, saves production cost.
Description of drawings
Fig. 1 is the core thigh structure chart of the band bundled layer of all steel load radial line tire of the present utility model.
The specific embodiment
The specific embodiment represented below in conjunction with accompanying drawing elaborates to the utility model.
From accompanying drawing 1 as can be known, the band bundled layer of all steel load radial line tire of the present utility model, comprise rubber and be positioned at some core thighs of rubber that the core thigh of this band bundled layer is formed abbreviation 3+9 cord by three monofilament in the middle of being positioned at and 9 monofilament that are positioned at uniformly around these three monofilament.The density of core thigh in rubber is per 10 centimetres 60.Some core thighs in rubber constitute the cord of tires, and described cord has and do not twine silk outward, for line contacts, are twisting in the same way between the monofilament between the monofilament.This 3+9 cord strength is big, do not have outer silk, the twisting and contact for line in the same way of twining, can satisfy carcass to the cord performance demands, and the antifatigue of tire and wear resistance are improved, when reaching lightweight tire purpose, reduce cost,, prolong tire service life.
For developing lightweight, high performance all steel load radial line tire, 11R22.5,11R24.5 on the basis of former carcass applications 3+9 * 0.22+0.15 cord, Application and Development 3 * 0.24+9 * 0.225CCHT cord.The 3+9 cord diameter is little, after steel wire diameter changes, carcass cord calendering thickness is adjusted into 2.1mm by original 2.3mm, attenuate calendering cord thickness, reduce the calendering sizing compound consumption, thereby lightweight tire, reduce resistance to rolling, improve anti-wear performance, prolong the service life of tire, when improving cord strength, reduce the cord consumption, reduce cost, and reach light-weighted purpose.
Claims (2)
1. the band bundled layer of an all steel load radial line tire comprises rubber and is positioned at some core thighs of rubber, it is characterized in that: the core thigh of this band bundled layer is made up of three monofilament in the middle of being positioned at and 9 monofilament that are positioned at uniformly around these three monofilament.
2. the band bundled layer of all steel load radial line tire according to claim 1, it is characterized in that: the density of core thigh in rubber is per 10 centimetres 60, and some core thighs in rubber constitute the cord of tire, and cord does not have the outer silk that twines, be the line contact between the monofilament, be twisting in the same way between the monofilament.
