Abstract
The invention relates to a reinforcing type liner layer structure, comprising an air tight layer and a transition layer which are overlapped with each other, wherein the inner side of the transition layer and the outer side of the air tight layer are bonded together; and the inner side of the air tight layer is in contact with a tire tube. The liner layer structure is characterized in that a reinforcing rib is bonded on the outer side of the transition layer; the thickness of the air tight layer, the transition layer and the reinforcing layer contract from the direction of a center line to both ends respectively; the transition layer is longer than the air tight layer; and the air tight layer is longer than that reinforcing rib. The liner layer structure is in a central symmetry structure. The tire-reinforcing type liner layer structure provided by the invention can avoid the phenomenon of shortage of partial materials caused by the deep stretching of the liner layer, so that the inspection pass rate of tires is improved.
Description
Technical field
The present invention relates to a kind of inside liner structure of tire, especially a kind of reinforced type inside liner structure.
Background technology
Existing wheeled car runs quickly on express highway, should be fast safety but also energy-conservation again, this wherein tire liner play an important role.The inside liner of tire mainly comprises two: one, air-retaining liner, and this layer sizing tyre cavity plays a part air-tightness and contacts with the inner tube of a tyre; Two, cambic horizon, this layer sizing plays the relation that connects air-retaining liner and carcass.Inside liner reasonable in design can improve tyre air tightness and safety, plays the high efficiency hauling operation that Duola hurries up.
The bonding general employing stacking pattern (as shown in Figure 1 and Figure 2) of tire cambic horizon 2a and air-retaining liner 1a in current each tire enterprise, the inside liner of this form is in later stage use procedure, because local area stretches bigger than normal, easily cause finished tire to occur that tyre cavity shows line problem, the air-tightness and the inner tube of a tyre easy to wear that destroy tire cause potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of reinforced type inside liner structure is provided, solved inside liner because high elongation occurs the phenomenon of local material deficiency having improved tire inspection qualification rate.
According to technical scheme provided by the invention, described reinforced type inside liner structure, comprise the air-retaining liner and the cambic horizon that are superimposed, the inner side of cambic horizon and the laminating of the outside of air-retaining liner, the inner side of air-retaining liner contacts with tire inner tube, it is characterized in that: at the outside of described cambic horizon lamination reinforcement bar, the thickness of air-retaining liner, cambic horizon and finishing strips shrinks to two ends from the direction of line of centers respectively.
The length of described cambic horizon is greater than the length of air-retaining liner, and the length of air-retaining liner is greater than the length of finishing strips.
Symmetrical structure centered by described inside liner structure.
Tire reinforced type inside liner structure of the present invention can solve inside liner because the phenomenon of local material deficiency appears in high elongation, improves tire inspection qualification rate.
Brief description of the drawings
Fig. 1 is the structural representation of inside liner in prior art.
Fig. 2 is the use constitution diagram of inside liner in prior art.
Fig. 3 is structural representation of the present invention.
Fig. 4 is use constitution diagram of the present invention.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 3～Fig. 4: as described in reinforced type inside liner structure comprise air-retaining liner 1, cambic horizon 2, finishing strips 3 etc.
As shown in Figure 3, Figure 4, the present invention includes the air-retaining liner 1 and the cambic horizon 2 that are superimposed, the outside laminating of the inner side of cambic horizon 2 and air-retaining liner 1, the inner side of air-retaining liner 1 contacts with tire inner tube, the outside lamination reinforcement bar 3 of cambic horizon 2; Symmetrical structure centered by described inside liner structure, inside liner structure is fitted in carcass inner side along its length; The thickness of described air-retaining liner 1, cambic horizon 2 and finishing strips 3 shrinks to two ends from the direction of line of centers respectively, thereby the thickness of air-retaining liner 1, cambic horizon 2 and finishing strips 3 is reduced to two ends successively along line of centers;
The length of described cambic horizon 2 is greater than the length of air-retaining liner 2, and the length of air-retaining liner 2 is greater than the length of finishing strips 3.
Inside liner structure of the present invention is fitted in the inner side of tire carcass along its length, finishing strips 3 is set on cambic horizon 2, effectively ensure the material abundance of inside liner structure in height extension region, greatly reduced the problem that the aobvious line of tyre cavity appears in finished tire, improved tire qualification rate.
