Abstract
The invention discloses a radial tyre using a round steel wire ring. The radial tyre comprises a tyre body consisting of a tyre crown, a tyre shoulder and a tyre side, wherein the steel wire ring and a tyre body layer for reversely wrapping the steel wire ring are arranged on the tyre ring part of the tyre side; the section of the steel wire ring is round; the steel wire ring is formed by winding single adhesive-attached steel wire. The stressed surface of the steel wire ring is 1/2 of the perimeter of the section, and the steel wire ring has the advantages of uniform stress, small stress state deformation, high safety multiple and the like, so that the radial tyre is safe to use and is longer in service life.
Description
(1) technical field:
The present invention relates to tire, be specially a kind of radial-ply tyre that uses circular steel wire ring.
(2) background technology:
Radial-ply tyre is comprised of body piles, bracing ply, bead coil and rubber conventionally, the framework material that wherein body piles, bracing ply and bead coil are tire, bear the suffered most stress of air-inflation tyre, comprise internal pressure stress and the road shocks stress of carcass.
In radial-ply tyre, body piles is at bead coil position upset anti-package, fixed tire size shock absorbing stress; Bead coil is closely fixed on wheel rim tire, and bears the various interaction forces of wheel rim and tire.
The bead coil of radial-ply tyre, because the stress being subject to is large, radial deformation is large, easily damages.In prior art, conventionally adopting cross section is hexagonal bead coil structure design, but the contact surface of cross section hexagonal bead and anti-package body piles is only several points, in tire motion process can there is relative displacement friction in body piles and bead coil, now each position of bead coil is stressed extremely inhomogeneous, easily causes body piles or bead coil abnormal friction heat-dissipating and fatigue damage.
(3) summary of the invention:
For the weak point of traditional polygon bead coil, the present invention proposes a kind of radial-ply tyre that uses circular steel wire ring, its object is further to improve force structure, reaches stressed uniform effect.
The present invention uses the technical scheme of the radial-ply tyre of circular steel wire ring, comprise the carcass being formed by crown, tire shoulder and sidewall, the tyre bead portion on described sidewall is provided with bead coil and bead coil is carried out to the body piles of anti-package, the cross sectional shape of described bead coil is circular unlike the prior art, and bead coil is formed by single attached glue steel wire wound.
Described steel wire adopts round wire.
According to the bead coil of different specification size, described steel wire diameter is chosen between ￠ 0.8mm～￠ 2.6mm.
The attached glue thickness of described steel wire is chosen between 0.05mm～0.20mm.
For keeping certain intensity, the diameter of section of described bead coil is bead width 40%～65%.
Beneficial effect of the present invention:
1, the present invention uses in the radial-ply tyre of circular steel wire ring, and bead coil bearing surface is perimeter of section 1/2, bead coil have stressed evenly, the advantage such as strained condition distortion is little, safety multiple is high.
2, with the present invention use safer, the life-span is more lasting.

Fig. 1 is the structural representation of one embodiment of the present invention.
Fig. 2 is the partial enlarged drawing at position, sidewall in Fig. 1 embodiment.
Fig. 3 is the structural representation of bead coil in Fig. 2.

(5) specific embodiment:
Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is described further:
The present invention uses the radial-ply tyre of circular steel wire ring to comprise by crown 1, the carcass that tire shoulder 2 and sidewall 3 form, in sidewall, 3 tyre bead 4 positions are provided with bead coil 5, triangle rubber 8 and body piles 6, 6 pairs of compound bead coils 5 of described body piles and triangle rubber 8 carry out anti-package to be fixed, improvements over the prior art of the present invention are the planform of bead coil 5, be that the cross sectional shape of described bead coil 5 is for circular, bead coil 5 is arranged and is made by single attached glue steel wire 7 continuous windings, in anti-package structure, body piles 6 is fitted with second circumference of bead coil 5, the stress equilibrium that tire is subject to is delivered on bead coil 5, as Fig. 1, Fig. 2, shown in Fig. 3.
Before bead coil 5 and triangle rubber 8 are compound, with the attached rubberized canvas of whole piece of certain width and thickness, the whole circle outside face of bead coil 5 is carried out to spiral winding, winding spacing is 30mm～50mm, is wound to finally, the head and the tail of attached rubberized canvas overlap mutually.
The diameter of section of described bead coil 5 is chosen as 40%～65% of tyre bead 4 width.
It is the round wire of ￠ 0.8mm～￠ 2.6mm that described steel wire 7 adopts diameter.
Can pass through to select the steel bead wire 7 of different-diameter and the total radical being wound around, and produce the bead coil 5 of different round section sizes:
1, the diameter ￠ 1.7mm of the circular steel wire ring 5(individual wire 7 of diameter ￠ 38, attached glue thickness 0.15mm, total radical 296).
2, the diameter ￠ 1.7mm of the circular steel wire ring 5(individual wire 6 of diameter ￠ 41, attached glue thickness 0.15mm, total radical 349).
3, the diameter ￠ 2.0mm of the circular steel wire ring 5(individual wire 6 of diameter ￠ 47, attached glue thickness 0.15mm, total radical 349).
The radial-ply tyre of different size need to be selected the circular steel wire ring of corresponding size according to design.
Claims (5)
