Description
Technical field
The present invention relates to a kind of bead coil composite members and apply its tire bead structure, belong to tire production manufacturing technology field.
Background technology
All-steel radial tyre owing to having fuel-economizing, wear-resisting, travelled distance is high, control stability and the series of advantages such as adhesion value is excellent, ratio shared in tire increases day by day, and is the developing direction of tire.Because all-steel radial tyre is mainly used on truck and bus, its particularity used just proposes higher requirements for quality to tire, comprises and will have high load capacity, large tractive force and good buffer capacity.Carcass and tyre bead are the main skeleton parts of tire, and wherein the effect of carcass is the intensity ensureing that cover tire is necessary, can bear certain air pressure and load, and the impact of outside.The effect of tyre bead is fixed on wheel rim by tire, prevents due to inflation pressure and External Force Acting and produce distortion, automobile is not rocked in motion.If these two positions go wrong, the safety performance of tire and automobile will be had influence on greatly.
But current domestic tyre industry is faced with so large problem: because all-steel radial tyre adopts hexagonal bead mostly, its stress concentrates the contact position appearing at end points and carcass inside bead coil, entirety is stressed to be concentrated on one wire, so just form obvious shearing stress to carcass cord to concentrate, when tire is in use subject to larger carrying application force, inside bead coil, steel bead wire and the carcass cord of end points directly contacts and friction occurs causes tire carcass intensity to decline, if friction excessively will cause carcass to damage, carcass cord single or overall fracture also can be caused time serious, blow out.Although also there is now the structure by being wound around nylon infantees outward at bead coil, but there is the runny shortcoming of sizing material in it, after tire building sulfuration, tyre bead portion is subject to mutual extruding and sizing material local can be caused very few, especially the very few situation of sizing material inside bead coil between the steel bead wire of end points and the carcass of anti-package bead coil is even more serious, thus is avoiding the limited use in steel bead wire and carcass cord excessive friction.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of bead coil composite members is provided and applies its tire bead structure, described bead coil composite members is applied in tire bead structure, can prevent carcass cord from directly contacting with the steel bead wire of end points inside bead coil, avoid the tire carcass intensity caused because of excessive friction to decline, thus substantially increase service life and the safety performance of tire.
According to technical scheme provided by the invention: bead coil composite members, comprises bead coil, it is characterized in that: be wound with high het expansion composite rubber strip outside described bead coil.

As the further improvement of described bead coil composite members, the winding angle of described high het expansion composite rubber strip on bead coil is 30-45 °.
As the further improvement of described bead coil composite members, the Clearance Between Wound of described high het expansion composite rubber strip on bead coil is 0 ~ 2mm.
As the further improvement of described bead coil composite members, described high het expansion composite rubber strip forms with the Composite rubber material refining of high thermal expansivity, and the Composite rubber material of described high thermal expansivity is mixing by rubber and plastic by the poly-vinyl resin and rubber that add high het expansion.
Described high het expansion composite rubber strip has following characteristics: 1, adopt high thermal expansivity material and rubber binding force strong; 2, can be high temperature resistant, can ensure, when serviceability temperature 50 degree, also there is higher thermal expansivity.
A kind of tire bead structure, comprise body piles, inside liner and triangle rubber composite members, it is characterized in that: also comprise steel wire rim of the mouth layer, the wear-resisting glue in sidewall and above-mentioned bead coil composite members, the lateral edges of described body piles surrounds bead coil composite members and is turned down, described steel wire rim of the mouth layer surrounds outside the turnover position of described body piles, and described triangle rubber composite members is fitted in bead coil composite members upper end and in local surrounded by the lateral edges of body piles; Described inside liner is fitted in the outside of steel wire rim of the mouth layer, the wear-resisting glue in described sidewall is arranged on the outermost layer of bead structure, described bead coil composite members, body piles, inside liner, steel wire rim of the mouth layer and triangle rubber composite members are all wrapped among the wear-resisting glue in sidewall, and the wear-resisting glue in described sidewall is used for contacting with wheel rim coordinating.
As the further improvement of described tire bead structure, described triangle rubber composite members comprises upper slice tri filling glue and the bottom sheet tri filling glue of complementary combinations, and the hardness of described upper slice tri filling glue is less than the hardness of bottom sheet tri filling glue.
compared with prior art, tool has the following advantages in the present invention:
(1) the present invention is wound around at bead coil compactness and the intrinsic shape of bead coil that high het expansion composite rubber strip ensures the steel bead wire arrangement of bead coil by wound form outward, suppress the radial displacement of bead coil in vehicle travel process, thus ensure that the endurance quality of tyre bead portion.
(2) the present invention adopts high het expansion composite rubber strip to carry out winding steel wire circle, it is compared with nylon infantees in the past, even if the sizing material inside bead coil between end points and body piles is fewer, but along with tire in use temperature rising, remaining adhesive tape can expand in Yin Wendu rising, indirectly add the spacing between end points and carcass cord cord inside bead coil, the steel bead wire of bead coil is stoped directly to contact with carcass cord, avoid friction, while guaranteeing bead support rigidity, carcass cord also can not be caused to rupture.In addition, described high het expansion composite rubber strip also can prevent moisture and moisture attack bead coil in the fabrication process.
