Description
Technical field
The utility model relates to a kind of tyre bead of surperficial sizing material presulfurization, belongs to motor tire preparing technical field.
Background technology
The radical function of tire is supporting vehicle body, buffering foreign impacts, realizes with the contact on road surface and ensures the rideability of vehicle.Especially all-steel radial tyre is everlasting under complicated and exacting terms and is used, and it subjects various distortion, load, power and high/low temperature effect in motion, therefore must have higher load-carrying properties, tractive property, cushion characteristic.The stress of the hexagonal bead that all-steel radial tyre adopts is concentrated and is appeared at end points place, inner side, entirety is stressed to be concentrated on one wire, so just form obvious shearing stress to carcass cord to concentrate, when being subject to larger carrying effect in tire used process, easily occur the single or overall fracture of carcass at bead coil position, thus it is quick-fried to produce tyre bead fracture of wire.
Summary of the invention
The purpose of this utility model easily ruptures the shortcoming causing tyre bead fracture of wire quick-fried in the bead coil position in order to solve tire in prior art, provides a kind of structure simple, compact to design, the tyre bead of durable surperficial rubber vulcanization.
The utility model adopts following technical scheme: a kind of tyre bead of surperficial sizing material presulfurization, comprise bead coil composite members, the outside face of described bead coil composite members is coated with body piles, the external sheath of described body piles has steel wire rim of the mouth layer, the inner side external sheath of described steel wire rim of the mouth layer has inside liner, described bead coil composite members comprises bead coil, described bead coil forms the arrangement of several loop configuration by a steel wire winding to be formed, the outer layer covers of described bead coil has nylon infantees, described nylon infantees surface is provided with the vulcanizate bed of material, the top of described bead coil composite members is fitted with upper bead filler and lower triangle rubber respectively.
Further, described upper bead filler and lower triangle rubber bonding connection.
Further, described bead coil is hexagon.
The utility model structure is simple, compact to design, adopt the nylon infantees through presulfurization to be coated on bead coil, improve the intensity of nylon infantees, and fricting shearing and phenomenon of rupture between the steel wire that can prevent sizing material from occurring because of flowing, effectively improve load-carrying capacity and the service life of tire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: bead coil composite members 1, bead coil 1-1, nylon infantees 1-2, upper bead filler 1-3, lower triangle rubber 1-4, body piles 2, steel wire rim of the mouth layer 3, inside liner 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of tyre bead of surperficial sizing material presulfurization, comprise bead coil composite members 1, the outside face of bead coil composite members 1 is coated with body piles 2, the outer lower part of body piles 2 is coated with steel wire rim of the mouth layer 3, the inner side external sheath of steel wire rim of the mouth layer 3 has inside liner 4, bead coil composite members 1 comprises bead coil 1-1, bead coil 1-1 forms several loop configuration by a steel wire winding, arrangement is formed, bead coil 1-1 is hexagon, the outer layer covers of bead coil 1-1 has nylon infantees 1-2, nylon infantees 1-2 surface is provided with the vulcanizate bed of material, the top of bead coil 1-1 is fitted with upper bead filler 1-3 and lower triangle rubber 1-4 respectively.
Preparation method: first presulfurization process is carried out to the surface size layer of bead coil 1-1 nylon infantees used 1-2 and makes the vulcanizate bed of material, then steel wire winding formed several loop configuration and arrange in hexagonal bead coil, the nylon infantees 1-2 of bead coil 1-1 through having the vulcanizate bed of material is wrapped up through spiral cloth-wrapping machine, upper bead filler 1-3 is posted respectively and lower triangle rubber 1-4 is combined into bead coil composite members 1 above bead coil 1-1, at the bonding body piles 2 of the outside face of bead coil composite members 1, the outer lower portion of body piles 2 divides coated layer of steel wire rim of the mouth layer 3, tyre bead is made at the external sheath inside liner 4 of steel wire rim of the mouth layer 3.
In the utility model, bead coil is after nylon infantees parcel, can fix bead coil 1-1, prevents bead coil 1-1 from scattering and prevents bead coil 1-1 to be subject to moisture and moisture immersion; The vulcanizate bed of material on nylon infantees 1-2 surface is after presulfurization process, and sizing material hardness improves, and inhibits distortion, improves the bulk strength of nylon infantees 1-2; Sizing material presulfurization inhibits the flowing power of sizing material, after preventing tire bead position to be squeezed when molding sulfuration, sizing material flows to other places, particularly save the sizing material between end points and carcass inside bead coil 1-1, prevent from carcass cord and steel bead wire from directly contacting to rub, thus can not because of tire in use occur load increase suddenly or overload situation time bead coil position there is the situation of the single or overall fracture of carcass cord.
