Abstract
The invention relates to an all-steel radial tubeless tire. An outer side end point of a rubber sheet below a crown is positioned between the inner side of the crown side and tire shoulder pad rubber; the inner side end point is positioned between a tire crown buffer rubber sheet and a No.4 (or zero degree) belt ply, and seals the end points of a No.2 belt ply, a No.3 belt ply and a No.4 belt ply (or zero degree). By the improvement of the tire crown structure, the rigidity of the tire crown is increased, so that the peripheral deformation in the driving process of a tire is relatively small, the rolling resistance is low, and oil is saved; meanwhile, the bonding force between the tire crown and the pad rubber is also intensified; the shearing stress among the belt plies is reduced, and the splitting among the belt plies as well as among the belt plies and the tire crown, which is caused by stress concentration and ultra high thermogenesis, is prevented, so that the durable safety of the tire shoulder part is improved greatly; the safety hazard of a tire in the aspects of over loading, high-speed long-distance transportation and the like is reduced; the service life of the tire is prolonged; the scheme is feasible, economic and reliable.
Description
Technical field
The present invention relates to the manufacture field of all-steel radial tire, especially a kind of full-steel radial ply with new crown structure
Tubeless tyre.
Background technology
The forties 20th century of radial comes out, due to the excellent performance that its unique structure is brought, through half
The development in many centuries, tire has gradually become meridian.Radial experienced very long with tortuous development, nowadays increasingly become
In flattening, tubeless, high speed, environmental protection and functionalization.With the development of auto industry, for the performance requirement of tire
More and more higher, has the advantages that the little fuel-economizing of good operation performance, rolling resistance and the all-steel radial tyre of excellent in durability become
The main force in tire industry.But, during all-steel radial tyre traveling, between crown and belt and belt often
Due to stress concentration, heat is excessive causes delamination between belt and crown, reduces Life of Tyre, causes when serious
Blow out, increase potential safety hazard.Thus, the structure design at crown position improves the important topic for having become world's tire.
The quality of radial crown structure directly affects the performance of tire, the row in the state of high-speed high-load
Sail, crown often becomes the position stood in the breach in tyre element by destroying.Therefore the anti-wear performance of crown must be strengthened, together
When reduce crown stress heat.
On the one hand existing technology can not effectively improve the bonding force between crown and belt, reduce shear stress,
Can not prevent caused by stress heat between belt and crown de- splits；On the other hand, the difficulty of technology is larger, carries significantly
The high cost of tire.
The content of the invention
For achieving the above object, deficiency of the prior art is overcome, the invention provides a kind of with the new of the lower film of hat
The full-steel radial ply tubeless tyre of type crown structure.The technology is increased by the film under one layer of hat of crown bottom laminating
The rigidity of crown so that in the process of moving circumferential deformation is less tire, rolling resistance is little, fuel-efficient.Meanwhile, the lower film of hat is on the one hand
The bonding force between crown and pad glue is enhanced, on the other hand concentrate because its closing belt end points effectively prevent stress,
Disengaging caused by heat is excessive between belt and crown, is greatly improved the durable and security performance of shoulder region, increases
The strong service life of tire, and scheme economy and facility, are that company increased benefit.
The present invention is employed the following technical solutions：
A kind of all-steel radial tyre of the new crown structure for being fitted with the lower film of hat, its structure is compound including crown
Part, shoulder wedge, belt, casingply, inner liner, sidewall and tyre bead；From outside to inside structure is successively crown composite members
The lower film of tread rubber, base rubber, breaker strip and hat.Described tire, it is characterised in that：It is close to ladle cord and anti-package in sidewall
Wire loop is to tire shoulder；The outer point of the lower film of hat is located between sidewall inner side and pad glue, and inner side end points is then slow positioned at crown
Rush between film and No. 4 (or 0 °) belts, and close the end points of 2,3, No. 4 (or 0 °) belts.
The tire of 4 layers of belt structure focuses principally on the performance in terms of high speed, and has the tire of 0 ° of belt structure
It is mainly used in high internal pressure, heavy duty aspect.Wherein No. 2, No. 3 belts be the main belt for fettering carcass；No. 1 belt is not only
Carcass can be fixed, the rigid transition between carcass and belt is also acted as；No. 4 belt tensile properties are good, protect 1-3 bands
Beam；0 ° of belt plays reinforcing 1-3 belt effects.
Preferably, the thickness for being preced with lower film is 1-3mm, and width is 60-80mm.
Preferably, be preced with the outer ledge of lower film to the distance on crown breaker strip side be 0-40mm.
Preferably, belt includes following two structures：A.1-3 number belt is combined 0 ° of belt；Number b.1-4 band beam
Layer.Wherein 1-4 belts are radially fitted successively along tire, and 0 ° of belt is then fitted in No. 3 belts in 0 ° of structure
Two ends.
Preferably, belt is made up of parallel steel wire and rubber, and steel wire and tire are in circumferentially 15- in 1-4# belts
50 ° of angles, steel wire direction is circumferential with tire consistent in 0 ° of belt.
Beneficial effects of the present invention are as follows：The present invention is improved crown structure, by trial production and durability
After testing, as a result show that the technology effectively strengthens the rigidity of crown, reduce crown circumferential deformation；Crown is improved with band beam
The bonding force of interlayer, reduces shear stress；The durable and security performance of crown is improve, oil consumption is reduced.It is worth mentioning
It is that the technical scheme is easy to implement in technique, practical, economic and reliable.
