Abstract
The utility model discloses a nylon seam allowance reinforcement layer structure of an all-steel tire tube radial tire. The nylon seam allowance reinforcement layer structure comprises an all-steel tire tube radial tire body and a sidewall, and a nylon seam allowance reinforcement layer is arranged between the all-steel tire tube radial tire body and the sidewall and is formed by two layers of nylon glue-adhering cord fabrics. The nylon seam allowance reinforcement layer structure improves durability of the all-steel tire tube radial tire on the basis of an ordinary all-steel radial tire, and particularly improves durability of a tire bead part. Experiment mileage proves that the durability and tire bead durability of the all-steel tire tube radial tire where the nylon seam allowance reinforcement layer is adopted can be improved greatly.
Description
Technical field
The utility model relates to a kind of all steel has inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer structure.
Background technology
All-steel radial tyre is a kind of version of tire, is different from diagonal tyre, semi-steel radial tire, band tyre etc.! Be commonly called as and be " rail tyre ".
The cord of meridian tyre body arranges and is different from diagonal tyre, and the cord of radial-ply tyre is not mutual cross arrangement, but with the cover tire section near parallel; The picture terrestrial meridian is arranged, and cord angle is little, is generally 0 °; Do not maintain intersection point between the body cord, when tire in the process of moving, the bizet ambient stress increases; Can cause circumferential extension, carcass radial breach.Therefore the bracing ply of radial-ply tyre adopts the cordline of nearly circumferential array, becomes 90 ° to intersect with the body cord angle, is generally 70 ° to 78 °; Form the rigid annular shaped band that almost can not uphold; Fix whole tire, the circumferential distortion of restriction tire, this bracing ply bears the internal stress of whole tire 60% to 70%; Become the main stressed member of radial-ply tyre, so be referred to as the bracing ply of radial-ply tyre.This shows that radial tire undertread design is very important, must have favorable rigidity, can adopt the multilayer wide-angle, high strength and be difficult for stretched fiber material is like steel wire or fibrous glass etc.
The advantage of radial-ply tyre has:
1) ground contact area is big, and adhesion value is good, and the tyre surface slippage is little, and is also little to the ground unit pressure, thereby rolling resistance is little, long service life.
2) crown is thicker and hard bracing ply is arranged, and is difficult for piercing through; When going the distortion little, can reduce oil consumption 3%～8%.
3) because curtain cloth layer is few, the sidewall is thin, so its radial elastic is big, cushion characteristic is good, and load-bearing capacity is bigger.
4) perfect heat-dissipating can adapt to high temperature, run at high speed.
The shortcoming of radial-ply tyre has: thinner because of the sidewall, crown is thicker, and the transition region on itself and sidewall is prone to produce breach.The side distortion is big, causes the lateral stability of automobile poor, and manufacturing technology requires high, and cost is also high.
Because it is wear-resisting that radial-ply tyre has, fuel-economizing, ride comfort, traction property, the characteristics that stability and high speed performance are good make it obtain the development that is exceedingly fast.Radial-ply tyre accounts for 80% of market in the world at present, and car and heavy load radial tire are respectively 90% and 63%.
All steel has inner tube of a tyre radial-ply tyre (especially 11.00R20 and 12.00R20 specification) because of being used for overload and abominable road surface, is easy to generate position, rim of the mouth infantile failure, as the rim of the mouth split, three-way split etc.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; Provide a kind of all steel that inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer structure is arranged; It has strengthened the endurance quality of common all-steel radial tyre, especially the tyre bead portion endurance quality.The experiment mileage confirms, adopts the utility model all steel to have all steel of inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer that inner tube of a tyre radial-ply tyre is arranged, and its endurance quality and tyre bead endurance quality significantly improve.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of all steel that inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer structure is arranged, and comprises that all steel has inner tube of a tyre meridian tyre body and sidewall, has at all steel to be provided with nylon rim of the mouth enhancement Layer between inner tube of a tyre meridian tyre body and the sidewall.
Said nylon rim of the mouth enhancement Layer attaches rubberized cord by two-layer nylon and constitutes.
The said nylon of the utility model rim of the mouth enhancement Layer is to attach rubberized cord by two-layer nylon to constitute, and in tire, between carcass and sidewall, sees from the distribution of material angle; Can realize material even transition and material by hard to soft transition; Protection carcass cord and steel wire rim of the mouth enhancement Layer end points improve the tyre bead portion tear resistance, postpone to subdue the time of damage; And delay to subdue destruction, realize the raising of tyres durable performance.
The utility model adopts a kind of enhancement Layer that attaches glue nylon cord as the position, rim of the mouth for postponing the rim of the mouth infantile failure, and it has strengthened the endurance quality of common all-steel radial tyre, especially the tyre bead portion endurance quality.The experiment mileage confirms, adopts the utility model all steel to have all steel of inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer that inner tube of a tyre radial-ply tyre is arranged, and its endurance quality and tyre bead endurance quality significantly improve.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1; The utility model provides a kind of all steel that inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer structure is arranged; Comprise that all steel has inner tube of a tyre meridian tyre body 1 and sidewall 2, has at all steel to be provided with nylon rim of the mouth enhancement Layer 3 between inner tube of a tyre meridian tyre body and the sidewall.
Said nylon rim of the mouth enhancement Layer by two-layer nylon attach rubberized cord 3-1,3-2 constitutes.
The said nylon of the utility model rim of the mouth enhancement Layer is to attach rubberized cord by two-layer nylon to constitute, and in tire, between carcass and sidewall, sees from the distribution of material angle; Can realize material even transition and material by hard to soft transition; Protection carcass cord and steel wire rim of the mouth enhancement Layer end points improve the tyre bead portion tear resistance, postpone to subdue the time of damage; And delay to subdue destruction, realize the raising of tyres durable performance.
The utility model adopts a kind of enhancement Layer that attaches glue nylon cord as the position, rim of the mouth for postponing the rim of the mouth infantile failure, and it has strengthened the endurance quality of common all-steel radial tyre, especially the tyre bead portion endurance quality.The experiment mileage confirms, adopts the utility model all steel to have all steel of inner tube of a tyre radial-ply tyre nylon rim of the mouth enhancement Layer that inner tube of a tyre radial-ply tyre is arranged, and its endurance quality and tyre bead endurance quality significantly improve.
The said nylon cord of the utility model attaches rubberized cord by two-layer nylon and forms as a kind of half-finished parts of radial-ply tyre, in tire, between carcass and sidewall, sticks in molding procedure when tire is made.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
