Abstract
The utility model discloses a reinforced seam allowance structure of all-steal tire nylon cord fabrics, wherein a tire body cord fabric (3), a steel wire wrapping chafer fabric (2) and a rubber layer (4) are sequentially coated on a steel wire ring (1) from inside to outside; the cross sections of the tire body cord fabric (3), the steel wire wrapping chafer fabric (2) and the rubber layer (4) are all U-shaped; the steel wire ring (1) is positioned at the bottom of the U-shaped circular arc; a nylon chafer fabric (5) is arranged between the steel wire wrapping chafer fabric (2) and the rubber layer (4); the outer ends of the tire body cord fabric (3) and the steel wire wrapping chafer fabric (2) are wrapped by one end of the nylon chafer fabric (5); the other end of the nylon chafer fabric (5) is positioned at the U-shaped arc formed by the cross section of the steel wire chafer fabric; and the cross section of the nylon chafer fabric (5) is C-shaped. With the utility model, the strength of a seam allowance is enhanced, the high-load resistance performance is improved, the rigidity and the flexural resistance properties of the seam allowance can be improved, and the quality problem that the seam allowance of a tire is flat due to the empty and breakage of the seam allowance is decreased.
Description
Technical field
The utility model relates to a kind of automobile all-steel radial tyre, relates in particular to automobile all-steel radial tyre sub-port structure.
Background technology
1, present all steel tyre rim structure mostly is the structure that no nylon cord is strengthened the rim of the mouth greatly, tyre rim position steel wire infantees 2, cord 3 anti-package end points are step and distribute, still can be under height overload situation behind the dispersive stress each end points the phenomenon of stress concentration appears.The mountains are high and the roads are steep in the southwestward, road is rugged wriggles, turn radius is little, tire pressure is higher in the tire use, 70% above load can accumulate on a certain group of tire when uphill/downhill and turning, if have on the road surface external force suddenly (as curb etc.) impact, steel wire is subjected to the stressed steel wire of stress concentration that the impact of external force causes suddenly under constantly crooked twisting deformation and stressed conversion load increases severely suddenly and is beyond the bearing capacity and ruptures, and cause stressed the redistributing and many meters happy chain reactions of steel wire, cause the explosion of tire.
The utility model content
Technical problem to be solved in the utility model is to provide all steel tire nylon cord of the outer end that a kind of step of protecting tyre rim position steel wire infantees, cord anti-package distributes to strengthen sub-port structure.
The technical solution of the utility model is as follows: a kind of all steel tire nylon cord is strengthened sub-port structure, comprise the bead coil in the tyre rim position, described bead coil is enclosed with the carcass cord from inside to outside successively, steel wire infantees and rubber layer, described carcass cord, steel wire infantees and rubber layer cross-sectional plane are " U " type, described bead coil is positioned at the circular arc-shaped bottom portion of this " U " type, its key is: be provided with the nylon infantees between described steel wire infantees and the rubber layer, described nylon infantees one end is with the steel wire infantees, the termination of carcass cord outer end is all wrapped up and being covered, this nylon infantees other end is positioned at the circular arc place that steel wire infantees cross-sectional plane forms " U " type, and described nylon infantees cross-sectional plane is " C " type.Described nylon infantees is that the double-layer nylon infantees is protected the steel wire infantees at tyre rim position, the outer end points that the step of cord anti-package distributes; The required nylon cord of this technology width is narrow, and the forming tire components assembling easily; And nylon cord consumption is little; Form the suitability for industrialized production of property in batches easily.
Above-mentioned carcass cord outer end point is than the outer end points height of steel wire infantees, and described carcass cord, the outer end points of steel wire infantees are step and distribute.
Beneficial effect: the utility model tyre rim position adopts the double-layer nylon cord that the outer end points of the step distribution of steel wire infantees, cord anti-package is protected; Increase rim of the mouth intensity, improved anti-height and carry performance, improved position, rim of the mouth rigidity and anti-flexural property, reduced the quality problems that bead separation splits the tyre rim explosion that causes.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the section drawing of tire;
Fig. 3 is for improving the scheme drawing of front tyre sub-port structure.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model all steel tire nylon cord is strengthened sub-port structure, comprise the bead coil 1 in the tyre rim position, described bead coil 1 is enclosed with carcass cord 3, steel wire infantees 2 and rubber layer 4 from inside to outside successively, described carcass cord 3, steel wire infantees 2 and rubber layer 4 cross-sectional planes are " U " type, described bead coil 1 is positioned at the circular arc-shaped bottom portion of this " U " type, carcass cord 3 outer end points are than steel wire infantees 2 outer end points height, and described carcass cord 3, steel wire infantees 2 outer end points are step and distribute.Be provided with nylon infantees 5 between described steel wire infantees 2 and the rubber layer 4, described nylon infantees 5 one ends all wrap up the termination of steel wire infantees 2, carcass cord 3 outer ends and covering, these nylon infantees 5 other ends are positioned at the circular arc place that steel wire infantees 2 cross-sectional planes form " U " type, and described nylon infantees 5 cross-sectional planes are " C " type.Referring to Fig. 2 is the structural representation of whole tire, and the tire middle part is a sub-port structure.
Utility model finished tire performance data
Indoor machine test: the true road traveling situation of simulation under the situation of tyre surface is being removed in the rim of the mouth durability test.Travel final hours as the important indicator of weighing the rim of the mouth load-carrying properties, this experimental result is all longer than the conventional tyre time of run before adjusting.
Utility model finished tire market condition of service
In September, 2009 exploitation is also thrown in 50 11.00R2018PR ☆ RLB11 utility model finished tires to the exceedingly odious road conditions in Sichuan with high overload area and is tried out; Preceding four backs eight vehicles, load is about 75 tons, and the tire use conventional tyre client of symptom this area fitness for purpose tires such as bead separation and rim of the mouth explosion do not occur in 4 months can be just satisfied with 3 months; In late March, 2010 phone is paid a return visit this batch of dealer tire condition of service, feeds back this batch tire still in normal use, and the more satisfactory client of effect is very satisfied, wishes the heavier-duty tire is formed seriation and scale.
