Description
Technical field
The present invention relates to tire manufacturing techniques fields, and in particular to a kind of to improve the skewed partition-type steel of carcass anti-package cord
Silk infantees.
Background technology
Pass through the solution subdivision of the tyre bead delamination and tyre bead circumferential direction breach all-steel radial tyre that are produced to single stage building machine
Analysis is found：Body cord arrangement there is a problem of whole skewed.The tire that there are problems that this, the stress being inflated under state
Analysis is found：Internal stress between each component increases and then carcass deformation is made to increase, when use be susceptible to uniformity it is bad and
The symptom such as early stage tyre bead delamination, tyre bead circumferential direction breach.
And cause carcass integrally skewed basic reason is the presence of steel wire infantees below fetus circle mouth wire loop, it is existing
Steel wire infantees fitting form be U packets, single stage building machine retainer process, when closing piece props up locking steel wire circle, active force
It first acts on steel wire infantees, it is skewed that steel wire infantees drives carcass to twist.
Original steel wire infantees is bonded form, as shown in Figures 1 and 2, steel wire during single stage building machine retainer
There is interaction between infantees and carcass, radical is up to 7-8 roots so that carcass anti-package cord integrally misplaces, and there are this
When in use, the internal stress between each component of tyre bead portion increases the tire of problem, Shear heating increases, and is susceptible to early stage tire
Enclose the symptom such as delamination, tyre bead circumferential direction breach.Therefore, to improve body cord integrally skewed problem, it is necessary to change steel wire packet
The fitting form of cloth.

A kind of to improve the skewed partition-type steel wire infantees of carcass anti-package cord, for tool there are two types of structure, one kind is two-piece type steel
Silk infantees, another kind are one chip steel wire infantees.
All-steel load-bearing radial tire is divided into tubeless OTR tire and has inner tube of a tyre all-steel load-bearing radial
Two kinds of tire.
As shown in figure 3, the two-piece type steel wire infantees that tubeless OTR tire uses, the inside packet of carcass 1
It is wrapped with wedged bottom hexagonal bead 2, the first side of carcass 1 is fitted with the first steel wire infantees 3, the bottom end of the first steel wire infantees 3
Be arranged in the left side position of wedged bottom hexagonal bead 2, the upper end side of the first steel wire infantees 3 along carcass 1 first side to
On extend to the outside of carcass 1.The second side of carcass 1 is fitted with the second steel wire infantees 4, and the bottom end of the second steel wire infantees 4 is set
It sets in the right edge position of wedged bottom hexagonal bead 2, the upper end side of the second steel wire infantees 4 is upward along the second side of carcass 1
Extend.The length of first steel wire infantees 3 is more than the second steel wire infantees 4.First steel wire infantees 3 does not wrap up with the second steel wire infantees 4
The lower face of carcass 1.Two-piece type steel wire infantees uses partition-type steel wire infantees in Fig. 3, avoids 2 lower end of wedged bottom hexagonal bead
There are steel wire infantees in face.
As shown in figure 4, have the two-piece type steel wire infantees that inner tube of a tyre all-steel load-bearing radial tire uses, the inside packet of carcass 1
It is wrapped with flat hexagonal bead 5, the first side of carcass 1 is fitted with the first steel wire infantees 3, the bottom end of the first steel wire infantees 3
It is arranged in the left side position of flat hexagonal bead 5, the upper end side of the first steel wire infantees 3 extends upwardly to tire along carcass 1
The outside of body 1.The second side of carcass 1 is fitted with the second steel wire infantees 4, and the bottom end of the second steel wire infantees 4 is arranged flat six
The upper end side of the right edge position of angular wire loop 5, the second steel wire infantees 4 is upwardly extended along the second side of carcass 1.First steel
The length of silk infantees 3 is more than the second steel wire infantees 4.Two-piece type steel wire infantees in Fig. 4 uses partition-type steel wire infantees, avoids putting down
There are steel wire infantees for 5 lower face of bottom hexagonal bead.
In order to reduce cost to reach identical effect, one chip steel wire infantees can be used.
As shown in figure 5, the one chip steel wire infantees that tubeless OTR tire uses, the inside packet of carcass 1
It is wrapped with wedged bottom hexagonal bead 2, the first side of carcass 1 is fitted with the first steel wire infantees 3, the bottom end of the first steel wire infantees 3
It is arranged in the left side position of wedged bottom hexagonal bead 2, the first side of the upper end edge carcass 1 of the first steel wire infantees 3 is upward
Extend to the outside of carcass 1.Steel wire infantees is not present in the lower face of wedged bottom hexagonal bead 2.
As shown in fig. 6, have the one chip steel wire infantees that inner tube of a tyre all-steel load-bearing radial tire uses, the inside packet of carcass 1
It is wrapped with flat hexagonal bead 5, the first side of carcass 1 is fitted with the first steel wire infantees 3, the bottom end of the first steel wire infantees 3
The leftward position in flat hexagonal bead 5 is arranged in side, and the first side of the upper end edge carcass 1 of the first steel wire infantees 3 is upward
Extend to the outside of carcass 1.Steel wire infantees is not present in the lower face of flat hexagonal bead 5.
The concept is that do not have steel wire infantees under wire loop, therefore single stage building machine is in retainer, steel wire packet
Interaction force is not present between cloth and body cord, so carcass anti-package cord is not in whole skewed situation, carcass
Cord and the arrangement of anti-package cord tend to theoretic radial cord arrangement, to promote the tyre bead performance of product.
By adjusting steel wire infantees position and fitting form, carcass anti-package cord dislocation radical is changed by original 7-8 roots
It is apt to 1-2 roots；Body cord and the arrangement of anti-package cord tend to theoretic radial cord arrangement, reduce carcass
Shearing force between deformation and component, finished product bead durability can promote original 156%.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the design of the present invention
It is defined with range, under the premise of not departing from design concept of the present invention, ordinary engineering and technical personnel is to this hair in this field
The all variations and modifications that bright technical solution is made should all fall into protection scope of the present invention, claimed skill of the invention
Art content is all documented in technology claim.
