Description
Technical field
The utility model is related to a meridian line tyre, more particularly to a kind of fibercord radial.
Background technology
The bead part of all-steel load-bearing radial tire is by wire loop, triangle rubber, carcass ply, chafer, son up and down
The position compositions such as mouth shield glue；Also have in carcass ply and chafer outer wrapping one or more layers fibercord, to improve tire
The rigidity of tyre bead and the carrying of tire and security performance.Because tyre bead stress is larger, it is desirable to have higher rigidity, could support compared with
Big load, the rigidity for raising tyre bead typically uses larger wire loop and triangle rubber, while bread one outside carcass ply
Layer wirecord fabric with reinforced bead position intensity and tyre bead rigidity, and undertakes the load suffered by tire as chafer.
Wire loop is the most basic part of tyre bead, carries the main function of banding automobile rim, and its top is that have higher
The lower triangle rubber (general hardness is in 80-90 degree) of hardness, so that it is with there is the rigid uniform transition of larger rigid wire loop,
The relatively low upper bead filler of hardness (typically in 50-70 degree) is compounded with above lower triangle rubber, so that whole tyre bead is from bottom to top
Hardness and rigid uniform transition.
Carcass ply passes through wire loop bottom by wire loop and triangle rubber complex bag in centre, the bread outside carcass ply
There is one layer of chafer, or one or more layers fibercord is wrapped up again outside chafer, its purpose is to increase tyre bead
Rigidity, enables tyre bead portion to undertake larger stress, improves tyre bead portion bearing capacity.
The wire loop and triangle rubber composite members that normal all-steel load-bearing radial tire is used at present are directly by carcass ply
Anti-package, wraps the technology of one layer of chafer again outside carcass ply, on the less middle-long distance truck of automobile load and car
Use, it is less with respect to problem, but used on the larger short-distance truck of automobile load, then often occur tyre bead come to nothing bulge,
The problems such as tyre bead breach so that earlier period damage occurs in tire, severe patient is blown out, and has a strong impact on the security of vehicle traveling.
The main cause for causing above mentioned problem is that short-distance truck loads are larger, therefore the deformation of tyre bead portion is also larger,
Because carcass ply modulus is larger, and upper bead filler modulus is relatively small (both modulus differ two orders of magnitude), between the two
Directly contact make it that modulus difference is excessive, easily produces larger shear stress, and being produced in tyre steel wire carcass anti-package end points should
Power is concentrated, and traveling causes this position to produce larger heat for a long time, tyre bead is occurred and is come to nothing bulge, simultaneously because the difference of modulus,
In tire production process, easily there is buckling phenomenon in the body cord of carcass outsourcing end points corresponding position, during tire running, carcass
Cord can be straightened, and in this reciprocation cycle for bending and stretching, due to the effect of shear stress, tire is often damaged here
Bad so that earlier period damage occurs in tire, severe patient is blown out, and has a strong impact on the security of vehicle traveling.
The content of the invention
The utility model is exactly in view of the deficienciess of the prior art, there is provided a kind of fibercord radial.
To solve the above problems, technical solution adopted in the utility model is as follows：
In a kind of fibercord radial, including tyre bead, triangle rubber, carcass ply and chafer, the tyre bead
Provided with wire loop, triangle rubber is long and narrow triangle colloid, and tyre bead is located at the bottom position of triangle rubber, and triangle rubber is coated with tire
Body cord, carcass ply is coated with chafer, and the carcass ply and chafer form the anti-of bending on the outside of carcass
To cladding, and the outsourcing end points of carcass ply is higher than the outsourcing endpoint location of chafer, tyre bead and triangle rubber the outer layer bag
Cover one layer of fibercord, fibercord bending fold and tyre bead and triangle rubber are coated on centre, the outsourcing end points of fibercord
Outsourcing endpoint location than carcass ply is high.
Further, the wire material of the fibercord and carcass is in the angle of 5~45 degree of angles.
Further, steel wire is provided with the chafer, chafer is externally provided with one or more layers fiber infantees, and fine
The outsourcing end points for tieing up infantees is higher than the outsourcing endpoint location of chafer.
Compared with prior art, implementation result of the present utility model is as follows for the utility model：
A kind of fibercord radial described in the utility model, one layer of 5- is pasted in tire bead and triangle rubber outer layer
The fibercord of 45 degree of angles, by wire loop and triangle rubber bag in centre, making the intensity of tyre bead portion further increases, and deformation subtracts
It is small；Make to form material hardness and rigid even transition between triangle rubber and carcass ply simultaneously, reduce carcass ply outsourcing
The stress concentration of end points, reduces heat, prevents from causing tyre bead to come to nothing；Higher thorn resistance is furnished with additionally, due to fibre curtain, can
Chafer outsourcing end points puncture triangle rubber repeatedly is avoided, tyre bead breach problem is caused, while preventing the cord of carcass ply from existing
Carcass ply outsourcing end points corresponding position is bent, and is reduced shear stress, is improved the tyre bead endurance of tire, solve because of tire
Circle intensity is not enough or is rigidly mutated the problems such as breach occurred in use, bulge, explosion, so as to improve tire running peace
The service life of full property and tire.
