Description
Technical field
The utility model is related to a kind of all-steel radial tyres.
Background technology
All-steel radial tyre bead structure has very important effect tire load.Tire is in driving process
In, tyre bead stress is very big, and tyre bead problem can seriously affect the service life and driving performance of tire.All-steel meridian line wheel in the world
Tire is in use, deflection and the high ratio about 14% of section, and the country of China is because of card passenger tyre the blowing pressure and load
Excessively high, the deflection and section ratios of normal tire rise to 20%~22%, lead to wheel rim nearby steel wire infantees, carcass etc.
Component stress increases, and bead material stress concentration causes tyre bead portion situations such as drum, breach, delamination often occur.Reinforce tire
Coil structures, raising tyre bead portion can rigidly ensure tire normally travel under high speed high-load condition, be to promote tire row
The most important thing sailed performance, reduce tyre bead defect incidence.
Since the ratio of tyre bead portion steel wire and rubber vulcanizate module is usually 30K~70K times, tyre bead portion material is more, stress
Complexity be easy to cause stress concentration, leads to material damage when tire changes rotating direction.Only with to material, component it is strong
Change means can not effectively solve the problems such as all-steel radial tyre tyre bead stability is poor, anti-high load capacity is low.Therefore,
Structural adjustment is to improve the key point of tyre bead performance.
Currently, part engineering tire is to promote tyre bead performance, ladle upper extreme point is set to the horizontal shaft position of section, and all steel
There has been no the products of this structure for card passenger tyre.In all-steel radial tyre bead structure, by increasing steel wire infantees anti-package
Highly, so that steel wire infantees anti-package endpoint is entered the simple region of stress in section, while adjusting carcass turn up height, ensure that it is anti-
Packet endpoint has a certain proportion of poor grade with steel wire infantees anti-package endpoint, it is possible to prevente effectively from the stress concentration of each component of tyre bead.Steel
Silk infantees cord strength, severing angle have great influence to its performance.Steel wire infantees intensity is too small, is unfavorable for protecting carcass,
And intensity is excessively high, the delamination be easy to causeing between ladle, carcass；Steel wire infantees severing angle is excessive, and tire rotating direction changes
When change, as stress is excessive to cause material damage.Therefore, using scientific and reasonable steel wire infantees intensity and severing angle,
It can effectively avoid tyre bead component because stress is by earlier period damage, while optimize steel wire infantees endpoint, the design of carcass turn up height,
Enhancing tyre bead intensity, the various problems for preventing tyre bead position, can greatly promote the service life of tire.

Anti-package layer；The tyre body curtain cloth anti-package wire loop, turn up height hc=hf*a, hf is flange height herein, and coefficient a is
0.5~1.6；The steel wire infantees lower extreme point originates in below wire loop on the outside of the horizontal point of contact of carcass, and encases rim area,
Steel wire infantees upper end point height i=(Ra-hf-RimDia/2) * b, herein i originate in above wheel rim, Ra is wheel crown part center
Carcass radius, RimDia are rim diameter, and coefficient b is 40%~55%.
Preferably, on the inside of the described steel wire infantees between carcass ply and liner layer, outside be located at carcass ply,
Between triangle rubber and sidewall, rim of the mouth shield glue.
Preferably, the steel wire infantees cord strength is the 60%~80% of body cord intensity.
Preferably, the steel wire infantees cord angle is 90 ° ± 10 °.
The utility model has an advantageous effect in that：
The utility model breaks through traditional all-steel radial tyre design concept constraint, optimization design tyre bead portion steel wire infantees
Endpoint location, carcass turn up height, steel wire infantees cord strength, steel wire infantees severing angle.Compared with prior art, using this
The all-steel radial tyre of bead structure is capable of the anti-load-carrying ability of effective fortified tyre, promotes bead durability energy energetically, carries
