Abstract
The utility model discloses a tyre protection bushing which is provided with covering layers and a reinforcement. A transverse reinforcement (2) is arranged between an upper covering layer and a lower covering layer of the bushing, and both sides of the upper and the lower covering layers are provided with side rubber. The crown part, the shoulder part, the tyre leg part of the bushing are circular variable cross-sections. The included angles between the lamellar body, meshed body and corpus body of the transverse reinforcement (2) are from 30 to 90 DEG. The utility model has the advantages of, load resistance, wear resistance, puncture resistance, impact resistance and driving transportation safety assurance, being suitable for the protection bushing between the outer and the inner tyres of an operated machine.
Description
The utility model belongs to the tire protection cover, particularly a kind of tire protection lining with raising tread life.
Develop rapidly along with auto-industry, communications and transportation has become important national economy industry, tire is the important elastic buffer component of transportation and various operation machineries, in being engaged in transportation and walking process, tire bears load, flexure deformation, makes tire tread wear, carcass produce breach or scuffing.After tire tread polished, carcass still had value of service, tire is taked to turn over entirely or take on turn over technology, improve tire service life and reduce traffic cost, the tire after the renovation can not reach the load level of new tyre, and carcass produces breach or scuffing, the general surface of tyre that adopts is repaired patterned heat, vulcanization forming, tyre surface vulcanizes evenly in conjunction with closely, and resistance to abrasion is good, improve tread life, but carcass distortion is bigger in vulcanization forming, easily cause aging, tyre rebuilding after the influence.
The purpose of this utility model is to overcome above technical deficiency, provides a kind of excellent performance anti abrasive tire protection lining.
Task of the present utility model is; the tire protection lining; have overplate and strengthen body; having transverse direction strengthener between upper and lower overplate is the fabric belt carcass; both sides are limit glue; transverse direction strengthener is netted, stratiform, restiform bodies structure, and 30-90 ° of the fabric belt carcass longitudinal angle of transverse direction strengthener increases horizontal pull and stretch intensity.
The tire protection lining; the transverse direction strengthener structure increases the bulk strength of lining, the perfect product structure of lining; have anti-pierce through, prevent breach, anti-deformation function; the bizet of lining, shoulder, tire shank are the ring-type variable section structure, use between the cover tire and the inner tube of a tyre, reduce tire pressure; improve tire and ground-surface adhesion value; cover tire does not enlarge damage, protects inside and outside tire, prolongs inside and outside tire service life.
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows tire protection lining section structure.
Fig. 2 shows tire protection lining front view.
The A-A view of Fig. 3 diagrammatic sketch 2.
The B of Fig. 4 diagrammatic sketch 3 is to view.
Among the figure, the 1-upper caldding layer; The 2-transverse direction strengthener; 3-lower caldding layer: 4-squeegee:
With reference to accompanying drawing 1,2,3,4; the tire protection lining; have overplate, strengthen body; be transverse direction strengthener 2 between the upper caldding layer 1 of lining, the lower caldding layer 3; both sides are limit glue, the lining bizet, and shoulder, tire shank are the ring-type variable section; transverse direction strengthener 2 is stratiform, netted, restiform bodies juxtaposition, 30-90 ° of the stratiform of transverse direction strengthener 2, netted, restiform bodies angle.
Make the tire protection lining; coating is laid 2 one-tenth 30-90 ° of transverse direction strengtheners then through mixing lower caldding layer 3 sizing material 1mm, rope footpath 0.5-1mm on sizing material on the heating loose tool; specification according to lining; transverse direction strengthener 2 is the 4-5 layer, upper caldding layer 1 sizing material 1mm, and matched moulds compresses patrix; the energising heating; temperature 70-90 ℃, moulding, time of cure 24-30h are cooled to finished product.
During use, according to tire size, the lining of adapted same size between the cover tire and the inner tube of a tyre, can use in entrucking.
Tire protection lining technical parameter:
Belt strap sandwich layer number layer 1-5
Strengthen body rope footpath mm 0.5-1
Horizontal pull and stretch intensity N/mm 20-100
Thickness mm 5
Specification in 6.50-23.25
The tire protection lining is applicable to the cover tire of various operation machineries and the protection linings between the inner tube of a tyre, and withstand load, wear-resistant anti-ly pierces through, shock resistance, guarantees the driving transportation safety.
Claims (3)
