Abstract
The utility model discloses an all steel radial tire adopting a novel four-layer belt ply structure. A no.1 belt ply is attached on tire body cord fabric and wound with a no.2 belt ply, and the no.2 belt ply adopts a circumferential enhancement layer which is spirally wound; a no.3 belt ply is attached on the no.2 belt ply; a no.4 belt ply is attached on the no.3 belt ply; and symmetric no.5 belt plies are arranged on two sides of the no.4 belt ply and above the no.3 belt ply and adopt circumferential enhancement layers which are spirally wound. According to the all steel radial tire adopting the novel four-layer belt ply structure, the tire shoulder rigidity is increased, the tire shoulder stress strain is reduced, the tire shoulder heat generation is reduced, and accordingly, the tire tread durability is improved; the spirally wound circumferential layers are adopted by the tire shoulder, so that the tire bearing capacity is further improved; and due to the fact that the circumferential enhancement layers which are spirally wound are adopted by the no.2 belt ply and two sides of the no.4 belt ply, the unbalanced quality caused by a zero belt ply connector of the tire is avoided, the tire uniformity is improved, and high-speed stability and operation stability of the tire are greatly improved.
Description
Technical field
The utility model relates to tire and manufactures field, especially a kind of whole steel wire radial tyre that adopts novel quadriply belt bundle layer structure.
Background technology
Bracing ply is the main stressed member of radial-ply tyre, and it is determining the primary stress that airtyred shape and the each position of tire are caused by interior pressure to a great extent.And bracing ply is born 60～70% of the caused stress of this interior pressure.Therefore, bracing ply should possess enough rigidity and the banding coefficient carcass ply with banding tire, and the adjacent circumferential expansion of restriction tire keeps the dimensional stability of tire.At present, whole steel wire radial tyre generally adopts the quadriply belt bundle layer structure of traditional zero-degree belt structure and intersecting angle.Wherein, traditional zero-degree belt structure is to adopt three layers of belt structure, and is circumferentially wound around the banded zero-degree belt of two-layer certain width in the 3rd bracing ply both sides, and its feature is that load carrying behaviour is good, but high speed uniformity is poor; And traditional quadriply belt bundle layer structure high-speed homogeneity is better, but load carrying behaviour is slightly poor.
The development of, top load high-speed in order to adapt to, anticyclonic high-velocity stream industry, research and development have at a high speed simultaneously and the heavy load radial tire of overload advantage becomes inevitable.In order to reduce traffic cost single time, logistics company has increased the volume of freight of single time, and the load of tire is increased, meanwhile, for the load-carrying capacity that makes tire strengthens, inflation pressure also increases accordingly, therefore, require tire to possess stronger load-carrying capacity and high speed performance simultaneously.
Summary of the invention
The purpose of this utility model is: a kind of whole steel wire radial tyre that adopts novel quadriply belt bundle layer structure is provided, it can meet endurance quality long-distance, rapid transit, can also meet the load-carrying properties of anticyclonic pressure, high load capacity, to overcome the deficiencies in the prior art simultaneously.
The utility model is achieved in that the whole steel wire radial tyre that adopts novel quadriply belt bundle layer structure, comprises carcass ply and is arranged on the bracing ply member on carcass ply, and the 1# bracing ply of bracing ply member is directly fitted on carcass ply; On 1# bracing ply, be wound with 2# bracing ply, the circumferential enhancement layer that 2# bracing ply is spiral winding, the circumferential angle of the steel wire of 2# bracing ply and tire is less than or equal to 1 °; On 2# bracing ply, be fitted with 3# bracing ply; On 3# bracing ply, be fitted with 4# bracing ply; Above the 3# bracing ply of the both sides of 4# bracing ply, be provided with symmetrical 5# bracing ply, the circumferential enhancement layer that 5# bracing ply is spiral winding, the circumferential angle of the steel wire of 5# bracing ply and tire is less than or equal to 1 °.
Described 1# bracing ply is that the severing of steel wire calendaring cord is made, and the circumferential angle of steel wire and tire is 15 °～90 °.
Described 2# bracing ply is taking the 1-9 root steel wire that is arranged parallel to each other as one group, and continuous helical is wrapped on 1# bracing ply, and the stretch ratio of steel wire is 2%～8%, and Steel Wire Surface is all covered with rubber.
Described 3# bracing ply is that the severing of steel wire calendaring cord is made, and the circumferential angle of steel wire and tire is 15 °～90 °.
Described 4# bracing ply is that the severing of steel wire calendaring cord is made, and the circumferential angle of steel wire and tire is 15 °～90 °.
Described 5# bracing ply is taking the 1-3 root steel wire that is arranged parallel to each other as one group, and continuous helical is wrapped on 3# bracing ply, and the stretch ratio of steel wire is 2%～8%, and Steel Wire Surface is all covered with rubber.
Owing to having adopted technique scheme, compared with prior art, the utility model improves the shoulder rigidity of tire, reduces the ess-strain of tire shoulder, reduces tire shoulder heat-dissipating, durable to improve crown; Shoulder adopts the circumferential enhancement layer of spiral winding also to improve the load-carrying capacity of tire; Because 2# bracing ply and 4# bracing ply both sides all adopt the circumferential enhancement layer of spiral winding, the maskant unbalance of having avoided tire to bring due to zero-degree belt joint, improve the homogeneity of tire, made the high stability of tire and road-holding property obtain larger raising.The utility model novel structure, result of use is good.
