Abstract
The utility model relates to a lining layer structure of a tire, in particular to a beveled edge type lining layer structure, and belongs to the technical field of tires. The lining layer structure comprises an airtight layer and a tire transition layer which are stacked together, wherein the inner side of the tire transition layer closely fits the outer side of the airtight layer; an airtight layer beveled edge with the thickness gradually reduced from inside to outside is arranged at the end part of the airtight layer; a tire transition layer beveled edge with the thickness gradually reduced from inside to outside is arranged at the end part of the tire transition layer. The lining layer structure is simple, compact and reasonable in structure; the air storage phenomenon caused by steps easily generated in the stacking process of the edges of the lining layer is solved; the tire test pass rate is improved; the tire airtightness is guaranteed.
Description
Technical field
The utility model relates to a kind of inside liner structure of tire, and especially a kind of inside liner structure of bevelled edge type, belongs to tyre technology.
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.
At present in each tire enterprise, the bonding general employing stacking pattern (as shown in Figure 1 and Figure 2) of tire cambic horizon 2 and air-retaining liner 1, but because cambic horizon 2 and the edge of air-retaining liner 1 are generally shaped as rectangle or semicircle, in stack rear edge, easily produce step, in tire production process, easily deposit gas herein, thereby there is hidden danger of quality in air-tightness and the generation of destruction tire.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of bevelled edge type inside liner structure, what solved that step that inside liner edge easily produces in additive process causes deposits gas phenomenon, the air-tightness that has improved tire inspection qualification rate and guaranteed tire.
The technical scheme providing according to the utility model, bevelled edge type inside liner structure comprises air-retaining liner and the tire cambic horizon being superimposed, tire cambic horizon inner side fits tightly with the outside of air-retaining liner, it is characterized in that: the end of air-retaining liner is provided with from inside to outside the thickness air-retaining liner diagonal-cut joint of attenuation gradually, the end of tire cambic horizon is provided with from inside to outside the thickness tire cambic horizon diagonal-cut joint of attenuation gradually.
Further, the line of centers of the line of centers of air-retaining liner and tire cambic horizon overlaps
Further, air-retaining liner and tire cambic horizon are symmetrical along line of centers separately.
Further, air-retaining liner and tire cambic horizon diminish gradually from alignment both sides, center thickness.
Further, the length of tire cambic horizon is greater than the length of air-retaining liner.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, rationally, what solved that the step that easily produces due to inside liner edge causes in additive process deposits gas phenomenon, the air-tightness that has improved tire inspection qualification rate and guaranteed tire.

Fig. 1 is the structural representation of inside liner in prior art.
Fig. 2 is the scheme of installation of inside liner in prior art.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is scheme of installation of the present utility model.
Description of reference numerals: 1-air-retaining liner, 2-tire cambic horizon, 3-air-retaining liner diagonal-cut joint, 4-tire cambic horizon diagonal-cut joint.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Fig. 3 ~ 4, the utility model mainly comprises air-retaining liner 1 and the tire cambic horizon 2 being superimposed, and the outside of tire cambic horizon 2 inner sides and air-retaining liner 1 fits tightly, and the inner side of air-retaining liner 1 contacts with the inner tube of a tyre of tire.
The end of air-retaining liner 1 is provided with from inside to outside the thickness air-retaining liner diagonal-cut joint 3 of attenuation gradually, and the end of tire cambic horizon 2 is provided with from inside to outside the thickness tire cambic horizon diagonal-cut joint 4 of attenuation gradually.
The line of centers of the line of centers of described air-retaining liner 1 and tire cambic horizon 2 overlaps, and air-retaining liner 1 and tire cambic horizon 2 are symmetrical along line of centers separately.
Described air-retaining liner 1 and tire cambic horizon 2 diminish gradually from alignment both sides, center thickness.
The length of described tire cambic horizon 2 is greater than the length of air-retaining liner 1.
Inside liner structure described in the utility model is fitted in the inner side of tire carcass along its length, tire cambic horizon and air-retaining liner end adopt bevelled edge form replace rectangle or semicircle, be convenient to the exhaust in inside liner rolling process in tire production process, what solved that the step that easily produces due to inside liner edge causes in additive process deposits gas phenomenon, the air-tightness that has improved tire inspection qualification rate and guaranteed tire.
