Description

A kind of tire wire loop structure, winding disc and winding method

Technical field

The present invention relates to a radial tire ring traveler, wind the winding disc and its winding method of the wire loop structure.

Background technology

Existing radial structure is usually carcass ply around wire loop bottom anti-package to tire outside, steel used Wire ring structure is usually hexagonal structure or quadrilateral structure, in tyre inflating in use, radial tension meeting on body cord Wire loop is passed to, wire loop bottom easily forms cusp with carcass ply and contacts, and then in the position of cusp and tire of wire loop Body produces stress concentration and cuts off body cord, causes tyre explosion or accident occurs, heavy duty tire is particularly evident.

The content of the invention

In order to solve the above technical problems, the present invention proposes that one kind can reduce wire loop position of cusp to carcass ply active force Tire wire loop structure.

A kind of tire wire loop structure, the section of the wire loop structure is a similar round wire loop structure, it is certainly If center is outwards equipped with dried layer successively, each layer is equipped with some wire loops, and each layer is by last layer wire loop bag Wrap up in wherein, since the second layer of center outward, each layer of wire loop radical is n × 6, and the steel wire that whole wire loop includes is total Radical is：1+1 × 6+2 × 6+ ...（n-1）× 6, wherein, n is the number of plies；And every gauge of wire is equal.

Preferably, the polygonized structure of a similar round, the polygonized structure are formed on the bottom of the wire loop structure Every adjacent both sides between angle be 150 °.

Further, which is divided on symmetrical by the center line for horizontally passing through wire loop structure section Portion and lower part, its underpart are heptagon structure, and the angle between every adjacent both sides is 150 °.

Similar round wire loop structure of the present invention, its polycrystalline substance can realize Multi-contact with carcass ply, reduce steel Wire ring position of cusp is to the active force of carcass ply, compared with the wire loop structure of traditional hexagon or quadrangle, similar round Wire loop structure, can avoid because carcass ply the stress concentration that wire loop position of cusp single-contact produces and caused by cut off The problem of carcass, improve the bearing capacity and service life of tire.

The present invention proposes to realize the winding disc of above-mentioned tire wire loop structure winding.

A kind of winding disc of tire wire loop structure, winding disc are " U-like shape structure ", and " the U-like shape structure " is by seven Bar side forms, and the angle between every adjacent both sides is 150 °.

The winding disc of U-like shape structure of the present invention, designs for matching similar round wire loop structure, is twined as wire loop Pedestal during, makes steel wire play effective fixation and position-limiting action in the path winding process by setting, avoid Wander off or deform in winding process, so as to obtain required similar round polygon steel wire ring.

The present invention proposes a kind of method using above-mentioned winding disc winding steel wire coil structures, the similar round wire loop structure Once it is entwined on the winding disc of U-like shape structure by a steel wire, the steel wire passes through wire loop after attached glue, storing Under the control of the horizontal direction of wrapping machine head and the bidirectional displacement of vertical direction and the control of winding disc rotation angle, steel wire exists Under the guiding of pinch roller, reciprocal upward mode stacks winding in left-right direction since the one end on the most base of winding disc.

Preferably, the steel cord that the steel wire can be individual wire or more steel wires are twisted.

The method of the invention, stacks winding using a steel wire, can be configured on traditional wrapping machine from bottom to top Above-mentioned U-shaped structure winding disc is once entwined；On U shape profile, steel wire need to be only by the winding path of setting, a steel wire Similar round wire loop can be once wound out, spiral winding cloth is reused and is wrapped up, you can obtains a section very close to circle Wire loop of the shape without obvious cusp.

Embodiment

Embodiment 1.

A kind of tire wire loop structure of the present invention, the section of the wire loop structure is a similar round wire loop Structure, if it is outwards equipped with dried layer successively from center, each layer is equipped with some wire loops 1, and each layer is by upper one Layer wire loop 1 wraps up wherein, and since the second layer of center outward, each layer of 1 radical of wire loop is n × 6, whole wire loop The 1 total radical of the steel wire included is：1+1 × 6+2 × 6+ ...（n-1）× 6, wherein, n is the number of plies；And every gauge of wire is equal It is equal.

The bottom of wire loop structure of the present invention for similar round polygonized structure, the polygonized structure it is every Angle between adjacent both sides is 150 °.The wire loop structure is divided into symmetrically by the center line for horizontally passing through wire loop structure Upper and lower part, its underpart is heptagon structure, is 150 ° per the angle between adjacent both sides.

In order to realize the winding of above-mentioned wire loop structure, the present invention proposes a kind of twining for above-mentioned wire loop structure winding of auxiliary Drum 2, the winding disc 2 are " U-like shape structure ", and " the U-like shape structure " is made of seven sides, the folder between every adjacent both sides Angle is 150 °.

Specific winding method is as follows：The similar round wire loop structure is by a steel wire on the winding disc 2 of U-like shape structure Once it is entwined, steel wire passes through the two-way of the horizontal direction of bead winding machine head and vertical direction after attached glue, storing Under the control of 2 rotation angle of control and winding disc of displacement, steel wire is under the guiding of pinch roller, and one from the most base of winding disc 2 End starts reciprocal upward mode in left-right direction and stacks winding.The steel wire can be that individual wire or more steel wires are twisted Steel cord.

Embodiment 2.

The present embodiment is a test example.

The wire loop structure of the method for the invention winding is option A, using prior art hexagon wire loop structure as side Case B

The structure of option A is 1+6+12+18+24 similar round structures, totally 61 steel wires；

Option b is 5-6-7-8-9-8-7-6-5 hexagonal structures, and totally 61；

Through analyzing, calculating：

Under the same conditions, the strain energy density of the contact site of option A wire loop structure and carcass（SENER）Maximum be 2.551×e-2 mJ/mm³, the maximum of the strain energy density of the contact site of option b wire loop structure and carcass is 7.266 ×e-02 mJ/mm³, the peak value option b of strain energy is 2.85 times of option A；In terms of Mises stress, the steel wire loop knot of option A The Mises stress of the contact site of structure and carcass is 8.448e-01 MPa, the wire loop structure of option b and the contact site of carcass The Mises stress of position is that the peak value option b of 1.445e-00 MPa, Mises stress is 1.71 times of option A；It can be seen from the above that side Case A than option b stress evenly, option b wire loop structure is more concentrated with carcass contact site stress, carcass and steel wire loop knot Structure force-bearing situation, option A are substantially better than option b.
