Abstract
The invention relates to pattern tread rubber of a procured remolded tire. The pattern tread rubber comprises a tread rubber body, and a plurality of pattern grooves are formed in the tread rubber body. The pattern tread rubber is characterized in that a longitudinal broken line seam formed by sequentially connecting a plurality of line segments in an end-to-end mode is formed in the center line position of the tread rubber body in the length direction of the tread rubber body, transverse seams connected with vertexes of the longitudinal broken line seam are formed in the width direction of the tread rubber body, and the pattern grooves are formed between the transverse seams one by one. Compared with the prior art, the pattern tread rubber has the advantages that internal stress of transverse bending of the tread rubber is reduced by arranging the broken-line-shaped longitudinal broken line seam, and longitudinal cracks are not caused easily; internal stress of longitudinal bending of the tread rubber is reduced by arranging the transverse seams; cooling of tire shoulders is facilitated by arranging chamfered edge seams, and void and swell of the tire shoulders are reduced. The pattern tread rubber attached to a tire body of the procured remolded tire eliminates prestress, and is good in cooling effect and not prone to falling off, and the tire is long in service life.
Description
Technical field
The invention belongs to tire, particularly relate to the patterned tread glue that tire is reproduced in a kind of presulfurization.
Background technology
Prevulcanized tire tread rubber is rubber components for tyre rebuilding and special cold renovation technology.Be divided into heat to turn in the technique of tyre rebuilding to turn over cold, heat turn over technique be by tread rubber strip form and carcass shaping after sulfuration at high temperature under high pressure in mould; Coldly turning over, is under the tread rubber of presulfurization and carcass being molded over lower temperature and sulfuration under pressure.It is good that the cold quality specific heat turning over technique turns over technique, becomes current main technology mode.Low temperature presulfurization manufactures the old tire carcass that tire (being commonly called as cold retreads) carcass used refers to the formation after using of new tire again, by middle pad glue bond tread rubber on the old tire carcass of having polished, forms cold retreads.With decorative pattern on tread rubber, the contact area of existing tread rubber is as shown in Figure 1 large, and wearability is good, and driving force is strong, through being usually used in working truck tire in place.Its shortcoming is tire shoulder place heat radiation difficulty, easy generation is come to nothing bulge, and this decorative pattern can not be used for presulfurization manufactures tire again, reason is that presulfurization manufactures in the production process of tire again, and tread rubber prevulcanization is made, when the carcass of tread rubber and old tire is fitted, tread rubber occurs bending and deformation at length direction (longitudinal direction) and width (transverse direction), very large internal stress can be produced, it can be caused to come off and even damage carcass, make tire premature failure.
Summary of the invention
The present invention is to overcome deficiency of the prior art, provides the patterned tread glue that tire is reproduced in a kind of presulfurization, the carcass manufacturing tire again with presulfurization fit after patterned tread glue eliminate prestressing force, good heat dissipation effect, difficult drop-off, Using Life of Tyre is long.
The present invention for achieving the above object, be achieved through the following technical solutions, the patterned tread glue of tire is reproduced in a kind of presulfurization, comprise tread rubber body, tread rubber body is provided with some grooves, it is characterized in that: described tread rubber body central line position is provided with along its length and is connected successively the longitudinal broken line gap formed by many line segments head and the tail, and be provided with the transverse slot be connected with summit, described longitudinal broken line gap along its width, described groove is placed between transverse slot one by one.
Described groove both sides are provided with incline gap, and incline gap is along on the incline in tread rubber body length direction.
Described incline gap quantity is 1-5 bar, and incline gap and transverse slot are distributed between some grooves jointly.
The degree of depth≤1/3 tread rubber the body thickness in described longitudinal broken line gap, transverse slot and incline gap.
Beneficial effect: compared with prior art, the present invention reduces the internal stress of tread rubber transverse curvature by the longitudinal broken line gap arranging fold-line-shaped, and is not easy to occur longitudinal breach; The internal stress of tread rubber buckling is reduced by arranging transverse slot; Contributing to the heat radiation of tire shoulder position by arranging incline gap, reducing tire shoulder and to come to nothing bulge.The carcass manufacturing tire again with presulfurization fit after patterned tread glue eliminate prestressing force, good heat dissipation effect, difficult drop-off, Using Life of Tyre is long.

Detailed description of the invention
Below in conjunction with preferred embodiment, to according to detailed description of the invention provided by the invention, details are as follows:
Embodiment
Refer to accompanying drawing, present embodiments provide the patterned tread glue that tire is reproduced in a kind of presulfurization, comprise tread rubber body 1, tread rubber body is provided with some grooves 2, described tread rubber body central line position is provided with along its length and is connected successively the longitudinal broken line gap 3 formed by many line segments head and the tail, be provided with the transverse slot 4 be connected with summit, described longitudinal broken line gap along its width, longitudinal broken line gap 3 and transverse slot 4 are all not crossing with groove 2.Described groove is placed between transverse slot one by one.Described groove both sides are provided with incline gap 5, and incline gap is along on the incline in tread rubber body length direction.Described incline gap quantity is 1-5 bar, and incline gap and transverse slot are distributed between some grooves jointly.The degree of depth≤1/3 tread rubber the body thickness in described longitudinal broken line gap, transverse slot and incline gap.Longitudinal broken line gap, transverse slot and incline gap are all cut with cutting knife, because cutting knife is very thin, cutting knife is extracted rear gap out and is namely closed up, do not increase groove area, so tire-contact area does not reduce, wearability still can be kept to improve radiating effect and service life when keeping wearability, simultaneously difficult drop-off.The internal stress of the transverse curvature of tread rubber 1 can be reduced in longitudinal broken line gap 3, and because be bending and non-straight, so the middle part of tread rubber 1 is not easy to occur longitudinal breach.The internal stress of the buckling of tread rubber 1 can be reduced in transverse slot 4.The degree of depth of longitudinal broken line gap 3 and transverse slot 4 can be grasped flexibly everywhere, is unlikely to grooving and too deeply pattern block creeping deformation occurs.
The cutting groove depth in incline gap 5 and quantity can be grasped flexibly, and to contribute to the heat radiation of tire shoulder position, reducing tire shoulder bulge of coming to nothing is principle.Because the very thin cutting knife cutting of gap everywhere forms, cutting knife is extracted rear gap out and is namely closed up, and does not increase groove area, so tire-contact area does not reduce, still keeping wearability, improve radiating effect and service life when keeping wearability, simultaneously difficult drop-off.The tread rubber of this structure is better than the method increasing groove as can be seen here.When grooving length, direction, the degree of depth, quantity do not reach ideal effect, blade can be adjusted flexibly, and need not mold again.And it is high to do very thin die blade cost on mould, easily damages, and mould maintenance cost is high.Therefore, the present invention can also decrease pattern mould cost and mould maintenance cost.
Due to the more thinly-sliced cutter cutting in gap everywhere, do not increase groove groove area; Radiating effect and service life is improve, simultaneously difficult drop-off when keeping wearability.
Above-mentioned detailed description of the patterned tread glue that tire is reproduced in this kind of presulfurization being carried out with reference to embodiment; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under general plotting of the present invention and amendment, should belong within protection scope of the present invention.
