Detailed description of the invention
Below, embodiments of the present invention are described in detail.
The sectional view of an example of the pneumatic tire 1 that Fig. 1 is formed by manufacture method of the present invention for expression, above-mentioned pneumatic tire 1 has: the carcass 6 arriving the bead part 4,4 of both sides from fetus face 2 through sidewall 3 and the radial outside being configured in carcass 6 and belt 7 in the inside of fetus face 2.
Above-mentioned carcass 6 is formed by carcass ply the body more than one deck radially arranged by organic fiber body cord, is in this example to be formed by one deck carcass ply body 6A.This carcass ply body 6A is formed across the ring-type between above-mentioned bead part 4,4, and its two ends are not turn back around the bead core 5 being configured at each bead part 4 but clamped and be locked in this bead core 5 in the present example.Specifically, above-mentioned bead core 5 is made up of chip 5i, 5o inside and outside tire axial, at these inside and outside both ends that hold above-mentioned carcass ply body 6A between chip 5i, 5o.
Above-mentioned inside and outside chip 5i, 5o are by repeatedly being formed along tire circumference winding by the Bead silk 5a of non-elongate.Now, be preferably, the winding times of the Bead silk 5a of outer chip 5o than large such as about 1.2 ~ 2.0 times of interior chip 5i, thus makes rigidity be greater than interior chip 5i.Thereby, it is possible to total winding times of restriction Bead silk 5a, and relatively improve the flexural rigidity of bead part 4, contribute to improving control stability etc.Wherein, the label 8 in figure is the bead apex be made up of the vulcanie of rubber hardness such as 80 ~ 100 degree, erects from each chip 5i, 5o with tapered, improves tyre bead rigidity.In addition, rubber hardness represents based on JIS-K6253 and utilizes the Durometer A hardness that A type durometer measures under the environment of 23 DEG C in this manual.
In addition, above-mentioned belt 7 by more than two pieces, formed by two pieces of belt curtain cloths 7A, 7B in this example, wherein belt curtain cloth such as forms circumferential relative to tire for contour for steel cord elasticity belt cord with the angular array of about 10 ~ 35 °.Belt 7 improves belt rigidity by each belt cord mutual intersection between cord, makes the roughly overall with of fetus face 2 have clip effect and strengthens securely.In this example, to improve for the purpose of high speed durability, and be provided with string course 9 at the radial outside of this belt 7, the string course cords such as nylon cord are such as wound into helical form relative to circumference with the angle of less than 5 degree and are formed by this string course 9.As this string course 9, the full string course cord of the pair of right and left end string course cord only covering the tire axial outer end of above-mentioned belt 7 and the roughly overall with covering belt 7 can be used alone or suitably combinationally use.In this example, the example that string course 9 is made up of one piece of full string course cord is exemplified.
In addition, the thinner inner liner 10 forming tyre cavity face is configured with in the inner side of carcass 6.This inner liner 10 is such as made up of the rubber of the non-breathable such as butyl rubber, halogenated butyl rubber, keeps the filling air be filled in tyre cavity airtightly.In addition, configure the sidewall rubber 11 of the outer surface of sexual one-tenth sidewall 3 in the outside of above-mentioned carcass 6, and be configured with the tread-rubber 12 of the outer surface forming fetus face 2 at the radial outside of string course 9.
Then, the manufacture method of above-mentioned pneumatic tire 1 is described.This manufacture method comprises following operation: unvulcanized tire formation process S1, as roughly represented in Fig. 2, use the rigid type core body 20 with the ring-type of the profile consistent in fact with the tyre cavity shape of above-mentioned pneumatic tire 1, paste unvulcanized tire structure member successively at the outer surface of this rigid type core body 20, form unvulcanized tire 1N thus; Vulcanization process S2, as roughly represented in Fig. 3, puts into above-mentioned unvulcanized tire 1N in sulfurizing mould 21 together with above-mentioned rigid type core body 20 and carries out vulcanization forming.
Above-mentioned unvulcanized tire formation process S1 comprises following operation: the liner formation process of pasting inner liner 10 formation parts on rigid type core body 20; Paste the carcass forming process of carcass 7 formation parts; Paste the bead core formation process of bead core 5 formation parts; Paste the bead apex formation process of bead apex 8 formation parts; Paste the belt forming process of belt 7 formation parts; Paste the string course forming process of string course 9 formation parts; Paste the sidewall forming process of sidewall rubber 11 formation parts; And paste the tyre surface forming process etc. of tread-rubber 12 formation parts.
Wherein, in the operation except above-mentioned carcass forming process in above-mentioned unvulcanized tire formation process S1 and above-mentioned vulcanization process S2, suitably can adopt the known various method employing rigid type core body 20, therefore in this manual, only carcass forming process is described below.
As shown in Figure 4, in above-mentioned carcass forming process, use many pieces of rectangular cord sheets 13, and by these many pieces rectangular cord sheets 13, paste on rigid type core body 20 successively along tire circumference as shown in Fig. 5 (A), (B), thus form the carcass 6 of ring-type, wherein rectangular cord sheet 13 utilizes rubberizing 32 to cover the arrange body 31 of the body cord 30 alignd along tire axial and the cord of the less rectangular sheet of tire circumferential width L1.Now, be configured to each other at side edge part 13e, 13e of the adjacent rectangular cord sheet 13,13 of tire circumference, close to each other or to connect and not overlapping in fetus face 2.Thus in fetus face 2, the cord density of body cord 30 becomes roughly even, can guarantee the uniformity that tire is higher.In contrast, the overlapping portion J of above-mentioned side edge part 13e, 13e triangle overlapping one another must be formed in sidewall 3.Therefore at this overlapping portion J, the cord density of body cord 30 increases, so the convergent force local caused by body cord when vulcanization forming raises, the part that therefore there is above-mentioned overlapping portion J can be pushed inner liner 10 open and be exposed to the tendency in tyre cavity face.
Therefore, in the present invention, in the body cord 30 being configured at above-mentioned rectangular cord sheet 13, by being configured in the percent thermal shrinkage Ka of outermost outer body cord 30a when temperature 180 DEG C, the percent thermal shrinkage Kb of interior body cord 30b when temperature 180 DEG C is set smaller than.Thereby, it is possible to raise in above-mentioned overlapping portion J convergent force local when suppressing vulcanization forming.In this example, in above-mentioned rectangular cord sheet 13, each body cord 30 arranges with equal intervals P in fact.
In this example, make outer body cord 30a different with percent thermal shrinkage Ka, Kb of interior body cord 30b by changing cord material.Such as, the percent thermal shrinkage of aromatic polyamide fibre is roughly 0%, the percent thermal shrinkage of rayon fiber is roughly 1.5 ~ 2.5%, the percent thermal shrinkage of nylon fiber is roughly 2.3 ~ 3.3%, the percent thermal shrinkage of high modulus polyester fiber is roughly 3.5 ~ 4.5%, and the percent thermal shrinkage of conventional polyester (Regular polyester) fiber is roughly 4.0 ~ 5.0%.Therefore above-mentioned outer body cord 30a adopts the organic fibrous material that percent thermal shrinkage is relatively low, and interior body cord 30b adopts the organic fibrous material that percent thermal shrinkage is relatively high.
Wherein, as the additive method making percent thermal shrinkage different, such as can also in the previous stage forming rectangular cord sheet 13, externally body cord 30a implements to heat in advance, make it the thermal contraction produced in advance to a certain degree, or the tension force reduced cord is implemented when dipping (dipping) processes shrinks to the cord strengthened in impregnation process, thus percent thermal shrinkage when reducing sulfuration.
At this, when by unvulcanized tire 1N together with rigid type core body 20 put into carry out vulcanization forming in sulfurizing mould 21, unlike existing manufacture method, in sulfurizing mould, carry out making the so-called sulfuration of unvulcanized tire inflation to stretch (stretch).Therefore, when the percent thermal shrinkage Kb of interior body cord 30b is too small, during sulfuration interior body cord 30b because tension force is not enough bend alignment, thus likely damage the uniformity of tire.Therefore the percent thermal shrinkage Kb of interior body cord 30b is preferably more than 3.0%, is more preferably more than 4.0%.On the other hand, outer body cord 30a due to ratio shared in whole body cord 30 very low, even so when reducing percent thermal shrinkage Ka, the impact caused uniformity is also very little, can uniformity be kept successively and suppress the rising of convergent force in the J of overlapping portion, a part of overlapping portion J can be suppressed to push inner liner 10 open and be exposed to tyre cavity face.
Therefore be preferably, the percent thermal shrinkage Ka of outer body cord 30a be set to less than 0.9 times of the percent thermal shrinkage Kb of interior body cord 30b, be more preferably less than 0.8 times, most preferably be less than 0.7 times.In addition, the lower limit of percent thermal shrinkage Ka allows for 0%, i.e. 0.0 times of percent thermal shrinkage Kb, but from the viewpoint of uniformity, is preferably more than 0.1 times.Wherein, if the percent thermal shrinkage Kb of interior body cord 30b is excessive, then body cord 30b can enter or in inner liner 10, easily produce cord loose.Therefore the upper limit of above-mentioned percent thermal shrinkage Kb is preferably less than 6.0%.
In addition, in inside and outside body cord 30a, 30b, the modulus Mo of every root cord of outer body cord 30a is preferably made to be below the modulus Mi of every root cord of interior body cord 30b, especially from the viewpoint of uniformity, be preferably Mo/Mi < 1.0, be more preferably 0.2 < Mo/Mi < 0.8.Wherein, above-mentioned modulus is the initial elongation opposing degree of every root cord that the chemical fibre tyre cord test method of foundation JISL1017 is obtained, represent in " load-elongation " curve of the cord obtained according to identical test method, near initial point, load change is the slope of above-mentioned " load-elongation " curve near tangent at maximum maximum point place relative to variable elongation.
In addition, if the width L1 of the tire circumference in above-mentioned rectangular cord sheet 13 is excessive, then by rectangular cord sheet 13 from fetus face 2 through sidewall 3 to tire radial direction inner side bending, easily there is fold and produce the at random of cord.In addition, because the overlapping widths Wj of the circumference in the J of overlapping portion also broadens, so the radical of the body cord overlapped in the J of overlapping portion also increases, thus effect of the present invention cannot be given full play to.On the contrary, if the width L1 of tire circumference is too small, then the increase of adhering processes number of rectangular cord sheet 13, the decline of sticking efficiency is caused.Therefore above-mentioned width L1 is preferably the scope of 10 ~ 30mm, and the radical of body cord 30 in above-mentioned arrange body 31 is preferably 10 ~ 30.
In addition, the overlapping radical N of the body cord 30 in above-mentioned overlapping portion J, is 1 ~ 2 at tire Breadth Maximum position Qm, is more preferably 1.Therefore in order to make above-mentioned overlapping radical N originally be in above-mentioned scope, and preset rectangular cord sheet 13 above-mentioned width W 1 and on fetus face 2 along the side edge part 13e interval etc. each other of the adjacent rectangular cord sheet 13 of tire circumference.
Above, particularly preferred embodiment of the present invention has been described in detail, but has the invention is not restricted to illustrated embodiment, also can be deformed into various mode to implement.
