All steel load tyre patching
Technical field
The invention belongs to tyre repair technical field, particularly relate to a kind of tyre patching.
Background technology
Along with the high speed development of modern logistics, carrier is develop rapidly thereupon also, and the use of various all steel load tires is more and more extensive, and because vehicle capacity is large, road conditions are complicated, so its tire often damages, and need to adopt tyre patching to repair.
The basic structure of existing tyre patching is generally film or the irregular circular film of rectangle, in film, embed the intensity that has nylon wire or thin short steel wire to increase sticking patch, by adhesive linkage or the employing viscose glue arranging on sticking patch, be bonded in damaged tire inwall.The shortcoming that this tyre patching exists is:
1. because it is shaped as rectangle or irregular circular film, so can not fit completely, the arc inner wall of tire, causes laminating not tight, after packing the inner tube of a tyre inflation into, by the inner tube of a tyre, sticking patch is compressed and is fitted in tire inner wall, this sticking patch easily ftractures in tire used process.
2. for its intensity difference of sticking patch that embeds nylon wire, the easy secondary in tyre repair place damages.In order to strengthen sticking patch intensity, there is embedding the sticking patch of finer wire, finer wire is vertical or horizontal arrangement, and netted layout, it is often that part is furnished with steel wire, after the in use sticking patch fracture of this sticking patch, cause steel wire fracture, and then cover tire inwall and the inner tube of a tyre are caused to damage, greatly reduce Using Life of Tyre.
3. existing sticking patch adopts adhesive linkage or viscose glue to be adhesively fixed, and because its shape and cover tire inwall are not fitted, so adhesive effect is bad, can not be well and the bonding fusion of cover tire inwall be integrated.
4. existing sticking patch generally all adopts new rubber and steel wire to be made, and cost is very high, and waste resource.
Summary of the invention
Object of the present invention is just to provide a kind of all steel load tyre patching, and the sticking patch and the laminating of cover tire inwall that have solved prior art are not tight, bonding insecure, easily the technical problem of cracking.
Object of the present invention realizes by following technical proposals:
An all steel load tyre patching, comprises sticking patch body, the face of overlooking of this sticking patch body and look up face and be shaped as the wide olive shape in narrow centre, two ends.
Further, described sticking patch body all has certain radian on length direction and width.
Further, along the some steel wires of sticking patch body length direction parallel embedding arranged side by side.
Further, at the sticking patch body back side, be provided with the cryogenic vulcanization glue-line of one deck uncured.
Further, in the positive sulfuration of sticking patch, there is friction salient point.
Further, at sticking patch front zone line, be provided with grip rib.
Further, the whole original metal-cord cryogenic vulcanization glue of junked tire that adopts of described sticking patch body is made.
Further, described sticking patch body, cryogenic vulcanization glue-line, friction salient point and grip rib are one-body molded.
Because this sticking patch has said structure feature, when sticking patch bending is inserted in cover tire and is bonded in need to repair position time, make the region of this bonding sticking patch substantially consistent with cover tire inwall prototype structure, this region of recovery of large limit, to reset condition, guarantees that this repairing area has intensity and the serviceability that as far as possible approaches prototype structure to the greatest extent.It is compared with prior art sticking patch, and repairing quality is greatly improved, and repair rate obviously declines, and sticking patch obviously extends service life.
Compared with prior art, beneficial effect of the present invention is: simple in structure, reasonable in design, and can fit tightly with cover tire inwall, and utilize cryogenic vulcanization glue-line and cover tire inwall to be bonded as one, difficult drop-off is durable in use; The steel wire of parallel embedding guarantees that toughness and the intensity of sticking patch is enough, not easy to crack; Friction salient point and grip rib increase the frictional force of sticking patch and the inner tube of a tyre.

The specific embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
As shown in Figures 1 to 4, a kind of all steel load tyre patching, comprises sticking patch body 1, and the whole cryogenic vulcanization glue that adopts of this sticking patch body 1 is made, the face of overlooking of sticking patch body 1 and look up face and be shaped as the wide olive shape in narrow centre, two ends.
Described sticking patch body 1 all has certain radian on length direction and width.When sticking patch is inserted the inner also bending of cover tire, this sticking patch degree of crook is consistent with cover tire inwall, thereby sticking patch and cover tire inwall are fitted completely.
Along the some steel wires 2 of sticking patch body 1 length direction parallel embedding arranged side by side, these steel wire 2 length are consistent or basically identical with sticking patch body 1 length, and steel wire 2 is all consistent with steel wire model, specification in metal-cord in original-pack tire.
At sticking patch body 1 back side, be provided with the cryogenic vulcanization glue-line 3 of one deck uncured, in the positive sulfuration of sticking patch, have friction salient point 4, in sticking patch front, zone line is provided with grip rib 5.
Because this sticking patch has said structure feature, make this sticking patch consistent with cover tire inner wall shape after bending, cryogenic vulcanization glue-line 3 by its back side utilizes rubber cement to be bonded in the position that needs repairing, tire in the course of the work its internal temperature raises, and makes after 3 fusings of cryogenic vulcanization glue-line completely and the bonding fusion of fitting of cover tire inwall is integrated.And the friction salient point 4 in sticking patch front and the grip rib 5 of front zone line can be strengthened the frictional force with the inner tube of a tyre, guaranteeing does not have relative sliding between the inner tube of a tyre and cover tire.
As preferably, described sticking patch body 1, cryogenic vulcanization glue-line 3, friction salient point 4 and grip rib 5 are one-body molded.The whole cryogenic vulcanization glue that adopts of this sticking patch body 1 is made, thereby its back side forms cryogenic vulcanization glue-line 3 without carrying out vulcanizing treatment, front zone line compacting grip rib 5, remainder sulfuration place friction salient point 4.
It is that raw material carry out processing and fabricating that the application's sticking patch can adopt the original metal-cord in junked tire completely, turns waste into wealth, not only reduce production costs, and Resource Recycling Utilization, avoid the wasting of resources.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
