Abstract
The invention discloses a molding method of a high-speed-resisting belted layer of an off-road vehicle tire. Aramid cord fabrics are used as #1 to #4 belted layers; #5 to #6 belted layers are made of nylon cord fabrics; the nylon cord fabric with the width of 30mm to 50mm is used, and each two layers of the nylon cord fabrics cover two end parts of the belted layers; the end parts are filled through adopting edge covering rubber strips with the width of 10mm to 20mm. Ultrahigh-strength aramid cord threads are used as #1 to #4 belted layers of a stressing main body for bearing driving stress of the tire; the number of layers of the belted layers is reduced and the heat generated by the tire is reduced. The #5 to #6 belted layers are made of the nylon cord fabrics with relatively sparse linear density so that the bonding of the cord threads and rubber is good; meanwhile, a cutting-off angle of the #5 to #6 belted layers is 80 degrees or more, so that the hooping effect of the middle part of a crown of the tire is enhanced and the strain caused by the fact that the tire rolls is reduced; the two end parts of each two layers of belted layers are covered with the large-angle nylon cord fabrics and the rubber strips with low heat generation are filled, so that the rigidity of the end parts of the belted layers can be enhanced; high-frequency deformation and heat generation in a high-speed driving process are reduced, so that high-speed performance of the off-road vehicle tire is improved.
Description
Technical field
The present invention relates to the belt structure of tire, specifically a kind of molding side of the off-road tire belt of resistance to high speed
Method.
Background technology
The offroad vehicle in past, travels typically all on the poor road of road conditions, and for meeting tyre surface anti tear, anti-puncture will
Ask, adopt lugtread pattern, pattern block is thicker abundant more, its belt structure is+3 layers of steel belt of 0 degree of belt
Or four layers of steel belt with cushion.Current offroad vehicle often in conventional road, especially running on expressway,
Speed reaches more than K level, and at this moment the belt of former tire can produce Shear heating, and heat is too high to be led under belt intensity
Fall, causes the faults such as belt delamination, cords break, the accident of blowing out when serious.
Content of the invention：
The purpose of the present invention is a kind of cross-country vehicle wheel providing for overcoming the shortcomings of the resistance to high speed performance of existing off-road tire
The forming method of the tire belt of resistance to high speed.
The technical scheme realizing the object of the invention is：
A kind of forming method of the off-road tire belt of resistance to high speed, comprises the steps：
（1）Rouse fit successively 1# belt, 2# belt in band beam forming；
（2）Fit in the end of 1# belt, 2# belt and fill low-heat-generation bound edge adhesive tape, cover termination；
（3）Use bound edge belt cladding 1# belt, the both ends of 2# belt two-layer again；
（4）The termination of every layer of belt is staggered not overlapping；
（5）According to step（1-4）Method fit successively 3#, 4# belt, 5#, 6# belt, and accordingly coat bound edge adhesive tape
With bound edge belt；
Described belt 1#-6#, totally 6 layers；
Described 1#-4# belt, using aramid fiber cord；
Described 5#, 6# belt, using nylon cord fabrics；
Described bound edge adhesive tape width 10-20mm；
Described wrapped belt bundle slice width 30-50mm；
The severing angle of described 5#, 6# belt takes more than 80 °.
The positive effect of the present invention is：Using superhigh intensity aromatic polyamide cord as undertaking being advocated of tire running stress
1#～4# belt of body, on the premise of ensureing tire intensity, reduces the belt number of plies, and then reduces tire heat.5#～
6# belt adopts the sparse nylon cord fabrics of line density it can be ensured that cord is good with rubber adhesion；Meanwhile, 5#～6# belt
Severing angle takes more than 80 °, strengthens the banding effect in the middle part of tyre crown, reduces strain during tire rolling；Every 2 layers of belt
Both ends adopt the nylon cord fabrics cladding of wide-angle, and fill the adhesive tape of low-heat-generation, belt ends rigidity, fall can be strengthened
The low altofrequency deformation heat when running at high speed, thus improve the high speed performance of off-the-highway tire.
Brief description
Fig. 1 is a kind of structural representation of off-road tire belt of resistance to high speed of the present invention.
In figure：1.1# belt；2. 2# belt；3. 3# belt；4.4# belt；5. 5# belt；6.6# band
Bundle layer；7. bound edge belt；8. bound edge adhesive tape.
Specific embodiment
With example, the present invention is described in further details below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of forming method of the off-road tire belt of resistance to high speed：Fit on band beam forming drum 1# successively
Belt 1,2# belt 2；The bound edge adhesive tape 8 of both ends laminating 15mm, covers termination；Use the wide bound edge belt 7 of 40mm again
Cladding 1# belt 1, the both ends of 2# belt 2, should stagger in each belt termination, differential at least 5mm.According to the method described above according to
Secondary laminating 3# belt 3,4# belt 4,5# belt 5,6# belt 6, and accordingly cladding bound edge adhesive tape 8 and bound edge belt
7.
