Description
Technical field
The present invention relates to a kind of annular tire tread that contains belt, is a kind of parts that are used for the tyre rebuilding of truck and motor bus.
Background technology
Growing continuously and fast of world today's automobile pollution makes the consumption figure surge of tire, and in order to save resource, tyre rebuilding becomes countries in the world all in an environmental protection of development, the important channel of energy-saving and emission-reduction.But the traffic accident that is caused by retreads can be found everywhere, and is troubling, saves resource and formed very big contradiction with the security reliability of travelling, and also hindered the development of tyre rebuilding.
Because the belt of used old tire always has damage, the form of damaged is a lot, as belt wearing and tearing, steel wire fracture, corrosion, stab, Durchgangshohle, come to nothing, loosen, be out of shape or the like, check, judgement to damage are very complicated, and be difficult to repair, this is the principal element that causes the retreads explosion.Present various tyre retreading techniques such as tradition are renovated method, presulfurization strip tyre surface and annular tire tread renovation method, all belt is disregarded or simply repaired, lack effective solution, just select the less old tire of some damages to renovate, but cause the refresh rate of old tire very low so again, it is a very big wasting of resources that the old tire that has the intact and belt of many carcasses to damage can not utilize again, the damage of old tire and to the condition of the injury judge inaccurate, all be the accident potential of retreads, solve the security of retreads, reliability is the important topic of the old tire utilization of resources.
The patent No.: the 96115867.0 disclosed moving rubber nylon tread and the patent No.s: 00215750.0 disclosed annular tire tread, the main effect of the framework material in the described tyre surface is the bond strength that improves annular tire tread and carcass, all can not effectively solve the problem that tire belt damages.
Summary of the invention
Problem to be solved by this invention provides a kind of annular tire tread that contains belt, be used for truck and motor bus tyre rebuilding, the belt of replacement or reinforcement old tire when upgrading the old tire tyre surface, can save resource, reach the purpose of energy-saving and emission-reduction, reduce the tire cost, can guarantee that again retreads are safe and reliable.
Thinking of the present invention is that tire is divided into two parts, and one is carcass, and another is the annular tire tread that contains belt.The design safety multiple of carcass is very high, and is generally injury-free in the driving process, but the ratio of bearing load is much smaller than belt, and it is higher that it accounts for tire manufacturing cost ratio, so have very high value; Belt has born 60～75% internal pressure stress of tire, is again the parts of easy damaged.
The belt of new tire and tyre surface are to depend on also moulding together of carcass applying, sulfuration, be subjected to a lot of conditionalities, the process conditions complexity, and make simple that the new tire of technology of belt annular tire tread comes separately, adopt directly subsides and moulding, there is not the influence of the restraining force of carcass during sulfuration, stress condition is good, and sulfide stress is more than 6Mpa, far above new tire, the height of the new tire of strength ratio of belt annular tire tread, cost is lower.
Described belt annular tire tread is made up of tread rubber, base portion glue, steel wire belt and hose lining that outer surface has various anti-skid designs, the annular tire tread of the closure that the old tire carcass after its inner surface configuration and the polishing matches.
Commonly used truck and motor bus tire are divided into two big classes by structure, i.e. cross-ply and radial, and radial is divided into semi-steel wire radial tire and whole steel wire radial tyre again.The national standard adopting by equivalent of tire international standard, although the standard of each manufacturer's execution is identical both at home and abroad, performance indications such as physical dimensions such as the overall size such as the section of same specification tire is wide, diameter, tyre bead and allowable load, air pressure are basic identical, but the tread width of the belt structure of tire, cord arrangement, the number of plies, material, tire, tread radian height or radian, base portion glue thickness are not quite similar.
Because the degree difference of the belt damaged of old tire, therefore just need belt that annular tire tread contains the various ways and the number of plies with the demand that satisfies different retreads with reach most economical purpose.Annular tire tread includes belt and not necessarily also can not be fully be complementary with the belt and the damaged condition of former tire, but will select the contained belt structure and the number of plies in the annular tire tread in principle for use what help improving tire intensity.
The belt annular tire tread will have good versatility, suitability as parts, reduces its specification again as much as possible, therefore will optimize the parameter at each position of belt annular tire tread.
When assembling for the carcass that belt annular tire tread and polishing are got well certain magnitude of interference is arranged, the external diameter of belt annular tire tread is slightly less than new tire outside diameter.The external diameter of described belt annular tire tread is 98.5～99.8% of a new tire outside diameter.
The tread width is one of principal element that influences tread life, facts have proved, its distance travelled obviously improves during the tread width widen, when the tread width greater than with the section width of its adapted tire 84% the time, annular tire tread both sides glue-line has obvious thickening trend, be unfavorable for tire heat radiation, take place that the tire shoulder comes to nothing, tread edge is torn, fall the obviously aggravation of trend of blob of viscose.
The tread width of the retreads of prior art is all less than new tire, this is because the restriction of process conditions, the tread width that retreads are used just helps bonding less than the width of tire buffed surface, its tread width be lower than tire section width 74%, this also is the one of the main reasons that the distance travelled of retreads is lower than new tire.
The tread width of described belt annular tire tread is and 75～84% of the section width of its adapted tire.
The base portion glue of belt annular tire tread is between pattern groove bottom and belt, and its thickness is one of principal element that influences the annular tire tread internal diameter, relates to cooperating of annular tire tread and carcass.The diameter and the pattern depth of mould are fixed, can utilize the thickness of adjusting base portion glue to obtain the annular tire tread of different inner diameters, the base portion glue of annular tire tread can not be according to the ratio design of pattern depth as new tire design, and the thickness of the base portion glue of described belt annular tire tread should be controlled between 2～8mm.
The lower tread radian height of the employing of belt annular tire tread can reduce tire resistance to rolling, improve distance travelled, riding stability, with the adhesive force on ground etc., also help the shearing force and the Sheng Re that reduce between the belt, the tread radian height of annular tire tread prevents delamination, so will be lower than the new tire of same specification.The tread radian height of prior art retreads is by the decision of the radian of tyre crown buffed surface, the tire band the belt of arc, rigidity is strong, and presulfurization strip tyre surface or annular tire tread are attached on original belt, and its tread radian height is 4.5～6.5% of a tire section height.The tread radian height of described belt annular tire tread is 2.0～4% of a tire section height, and its tread radian is controlled between R500～1200mm.
The end opening width of described belt annular tire tread promptly with the width of carcass junction is and 78～90% of the section width of its adapted tire, or 1.03～1.1 times of tread width.
The number of plies of the belt of described belt annular tire tread can be one～six layer and not wait; What annular tire tread contained 1～2 layer of belt can carry out reinforcement to the original belt of tire, annular tire tread contains 3,4 layers of belt and can be used for replacing the original belt of tire, annular tire tread contains the tire replacing the original belt of tire or be used for specific (special) requirements of can be used for of 5,6 layers of belt, or by the belt of several different materials combinations.
The steel wire belt width of belt annular tire is wide, and the steel wire belt may slide into tread edge even can expose steel wire during sulfuration.The wideest width of steel wire belt of described belt annular tire tread is no more than 92% of tread width.
The belt of belt annular tire tread is divided into strengthening course, basal layer, transition zone and cushion, is divided into arranged askew again on the spread pattern and around arrangement, their cord arrangement angle and material are all different.Experimental results show that, when the cord arrangement angle of belt during greater than 77 °, the circumferential stiffness of tire strengthens, rolls and be out of shape, the trend that the shearing force of belt edges diminishes is obvious, the cord arrangement angle is big more, the tire circumference rigidity is strong more, reasonably designs the arrangement angle and the selection of annular tire tread belt cord, takes into account the needs of different kinds of tyre.The belt cord arrangement angle of described belt annular tire tread is 71～86 °.
The belt cord arrangement angle of described belt annular tire tread is 77～86 °, can be used as basal layer, strengthening course, transition zone and cushion belt and uses.
The basal layer of described belt annular tire tread, strengthening course belt, its cord arrangement angle is 71～74
The transition zone belt of described belt annular tire tread is 26～28 ° with the close belt cord arrangement angle of carcass warp promptly.
The cord of described belt annular tire tread is arranged and is whole layer loopful around belt, it is 0～3.8 ° around lift angle β, can be used as strengthening course, basal layer and cushion belt, this belt can make the circumferential stiffness of annular tire tread the strongest, the most stable, belt is not subjected to shearing force, and moulding is simple, production efficiency height, its material adopt all-steel cord or the chemical fibre class cord of percentage elongation greater than 5% high twist more.
The belt structure of described belt annular tire tread, two ring-type belts are arranged, be symmetrically distributed in the both sides of another kind of belt, the width of two ring-type belts is respectively 25～55mm, it is 0～0.95 ° around lift angle, can be used as strengthening course, basal layer belt, its material adopts the all-steel cord of percentage elongation greater than 5% high twist more.
