The all-steel radial tire stopping opening structure is capable of increasing the position supporting performance of a stopping opening, increasing position bending rigidity of the stopping opening under a high load condition, increasing the capacity for scattering the stress in the end point position, and reducing the damage of the concentrated stress in the end point position to the tire.

Description

All-steel radial tyre toe mouth structure

Technical field

The utility model relates to automobile all-steel radial tyre field, relates in particular to a kind of all-steel radial tyre toe mouth structure.

Background technology

Present automobile all-steel radial tyre; The soft triangular rubber core, carcass cord, carcass cord, toe chewing-gum, sidewall rubber and the toe mouth that comprise inboard hard triangular rubber core, the outside are filled glue; Wherein said hard triangular rubber core and soft triangular rubber core are from inside to outside successively by carcass cord, carcass cord parcel; The tire toe structure inboard that is enclosed with carcass cord and carcass cord also is enclosed with inside liner, and the tire toe structure outside that is enclosed with carcass cord and carcass cord also is enclosed with the toe mouth and fills glue, and said tire toe structure lower end is encased by the toe chewing-gum; This toe chewing-gum is wrapped to form " U " shape, and said toe chewing-gum outer upper end end is surrounded by sidewall rubber.The traditional design mode is under mark carrier strip spare; The rich performance of toe mouth support performance and anti-song can satisfy the vehicle ' requirement; But to road conditions is not fine, and bend is bigger, and road conditions management is not the environment for use of standard very; Usage conditions such as overload, air pressure is higher, above toe mouth design ubiquity support performance is not enough, the rich ability drop of anti-song, stress are concentrated easily etc. causes quality problems such as tire toe is empty, quick-fried.

The utility model content

The utility model technical matters to be solved is to provide a kind of anti-song have mercy on ability, the better all-steel radial tyre toe of supporting capacity mouth structure.

The technical scheme of the utility model is following: a kind of all-steel radial tyre toe mouth structure; The soft triangular rubber core (8), carcass cord (2), the toe mouth that comprise inboard hard triangular rubber core (4), the outside are strengthened wirecord fabric (3), toe chewing-gum (5), sidewall rubber (6) and toe mouth filling glue (7); Wherein said hard triangular rubber core (4) and soft triangular rubber core (8) are strengthened wirecord fabric (3) parcel by carcass cord (2), toe mouth from inside to outside successively; The tire toe structure inboard that is enclosed with carcass cord (2) and toe mouth reinforcement wirecord fabric (3) also is enclosed with inside liner (1); Being enclosed with carcass cord (2) and toe mouth strengthens also being enclosed with toe mouth filling glue (7) outside the tire toe structure of wirecord fabric (3); Its key is: said inside liner (1) and inboard carcass cord (2) and toe mouth are strengthened being provided with individual layer nylon infantees (9) between the wirecord fabric (3), and said individual layer nylon infantees (9) encases carcass cord (2) and termination, toe mouth reinforcement wirecord fabric (3) upper end.

Above-mentioned tire toe structure lower end is encased by toe chewing-gum (5), and this toe chewing-gum (5) is wrapped to form " U " shape, and said toe chewing-gum (5) outer upper end end is surrounded by sidewall rubber (6).

Indoor lathe test: toe mouth durability test cycle is removing the true road traveling situation of simulation under the situation of tyre surface.Go final hours as weighing the important indicator that the toe mouthpiece carries performance, the tire toe durable test is along with its performance embodiment of increase of time is superior more, and test result sees the following form:

Through the checking of indoor test repeatedly, from test result analysis, the durable time of new scheme has surpassed more than the 100h, is more than doubled than the durable time of original design, and the preceence of whole toe mouth performance is very obvious.

Beneficial effect: the utility model improves toe mouth position support performance, can improve the bent rich rigidity in toe mouth position under the high load condition, improves endpoint location stress dispersibility, reduces the endpoint location stress concentration tire is destroyed.

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

As shown in Figure 1; A kind of all-steel radial tyre toe mouth structure; Strengthening wirecord fabric 3, toe chewing-gum 5, sidewall rubber 6 and toe mouth filling glue 7 etc. by hard triangular rubber core 4, the soft triangular rubber core 8 in the outside, carcass cord 2, the toe mouth of inboard forms; Wherein said hard triangular rubber core 4 is strengthened wirecord fabric 3 parcels by carcass cord 2, toe mouth from inside to outside successively with soft triangular rubber core 8; The tire toe structure inboard that is enclosed with carcass cord 2 and toe mouth reinforcement wirecord fabric 3 also is enclosed with inside liner 1, and the tire toe structure outside that is enclosed with carcass cord 2 and toe mouth reinforcement wirecord fabric 3 also is enclosed with the toe mouth and fills glue 7, and its key is: the carcass cord 2 of said inside liner 1 and inboard and toe mouth are strengthened being provided with individual layer nylon infantees 9 between the wirecord fabric 3; Said individual layer nylon infantees 9 is strengthened termination, wirecord fabric 3 upper end with carcass cord 2 and toe mouth and is encased; Nylon infantees 9 directions are consistent with toe mouth reinforcement wirecord fabric 3 inboard bearing of trends, and angle is 41 °, and width is about 70mm; The about 40mm of wirecord fabric inner top side end points is strengthened from the toe mouth in nylon infantees 9 upper extreme point positions, and the lower extreme point position is from steel wire infantees endpoint location 30mm.Improve cord end points H3 and steel wire infantees end points height H 1, H2 simultaneously, improve whole toe mouth support performance.Above-mentioned tire toe structure lower end is encased by toe chewing-gum 5, and this toe chewing-gum 5 is wrapped to form " U " shape, and said toe chewing-gum 5 outer upper end ends are surrounded by sidewall rubber 6.

Although more than combine accompanying drawing that the preferred embodiment of the utility model is described; But the utility model is not limited to the above-mentioned specific embodiment; The above-mentioned specific embodiment only is schematic rather than determinate, and those of ordinary skill in the art is under the enlightenment of the utility model, under the prerequisite of the utility model aim and claim; Can make multiple similar expression, such conversion all falls within the protection domain of the utility model.
