The specific embodiment
In the present embodiment, as shown in Figures 1 to 6, a kind of very-high performance oversize tire of the present invention, the specification of described very-high performance oversize tire is 305/25R32 108W, rim diameter is 32 inches, and rim width is 11J, and overall diameter is 965mm, section is wide is 313mm, loads as 1000kg.
Described very-high performance oversize tire preparation process is as follows:
(1) refining glue;
(2) making of parts;
A) tyre surface: according to decorative pattern groove feature, customized design has type tyre surface, solved bracing ply unfairness, the problem of base portion glue variable thickness, shape of the mouth as one speaks figure as shown in Figure 1, in described black box for there being the key point of type tyre surface, the reduction processing that thickness is done according to pattern groove, the thickness being different between the each point of common tyre surface is gradual transition;
B) sidewall: the sidewall of this specification profile is linear pattern, be different from the circular arc type sidewall of common tire, the sizing material in this profile region, sidewall when sulfuration flows large, be difficult to moulding, for this feature, customized design the sidewall shape of the mouth as one speaks, strengthen and to protect glue region, thickening sidewall rubber region, shape of the mouth as one speaks figure is as shown in Figure 2;
C) triangle rubber: the triangular rubber core height of ultralow section series specification is low, and hardness is large, anti-package difficulty, is head it off, at a side fluting of triangle rubber die panel, shape of the mouth as one speaks figure as shown in Figure 3, is fluting in described black box;
D) carcass: double-deck carcass structure, on 2# carcass 4, gluing sheet 3, guarantee that film 3 pads, in belt ends, prevent the friction of shoulder sky and minimizing band bundle and carcass, as shown in Figure 4;
E) inside liner: this specification adopts once-through method moulding, inside liner adopts the design of contrast level, and internal layer width is greater than outer width, effectively avoids the generation of tyre bead bubble;
F) bracing ply: bracing ply edge-wrapping adhesive adopts U-shaped bag;
G) cap strip: the string of a hat is wound around and adopts little S type, from starting point 1 to terminal 2, as shown in Figure 5;
H) bead coil: individual wire is wound around hexagonal bead;
(3) moulding: adopt advanced single stage method side bag hat production technology, for meeting this specification Production requirement, specific customization mechanical type one step processing drum, described moulding order is as shown in Figure 6;
(4) sulfuration: because this specification belongs to ultralow section series, interior profile is little, and general capsule size is improper, be difficult to meet sulfuration requirement, thus specific customization curing bag: folder edge internal diameter 550-620mm, overall diameter 750-820mm, bottom-to-top-height 440-480mm, section girth 500-580mm;
Because this specification cun number is excessive, during sulfuration sizing, capsule expands excessively, easily causes on capsule and alters, cause the fetus of sulfuration inclined to one side, occur the not first-class defect in breach, rim of the mouth, for addressing this problem, we are decided to be 0.02 ~ 0.03Mpa at the pressure of once shaping, secondary sizing pressure location 0.07 ~ 0.09Mpa;
Very-high performance oversize tire of the present invention and preparation technology's thereof beneficial effect is: by adopting high-performance tire outline design software to carry out structure design, optimize tire outline and inner structure, guarantee that tire various aspects of performance reaches requirement, also effectively reduce product development risk, reduced product development cycle simultaneously; Adopt special structure design and technology controlling and process means, guarantee that tire various aspects of performance reaches requirement, and realize continuity batch manufacturing.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
