Abstract

The utility model discloses an automobile vacuum tyre which can automatically conduct leakage repairing. The inner surface of the tyre is adhered with a silica gel leakage proofing layer without repairing of which surface is an even pressure layer and the even pressure layer is a plastic adding film of nylon net or plastic net frame. When the wheel tyre is pierced out by sharp objects, the adhesive gelly with high viscosity automatically fill the pore to prevent air leakage. The vehicle vacuum tyre without repairing of the utility model can automatically repair the pore pierced out by sharp objects without hot sulfuration or tyre injuring and thus the utility model is convenient, rapid, material saving and economic.

Description

A kind of filling car vacuum tire of exempting from

Technical field

The utility model relates to a kind of motor tire, but especially relate to a kind of automatic leakage-repairing exempt from filling car vacuum tire.

Background technology

Existing small passenger car tire is tubeless vacuum tire mostly, when it is punctured by iron nail and so on, will leaking gas lentamente, it is flat directly to cause tire, need reach car repair shop and adopt the special technology of vulcanizing tire patching this moment, if near do not have repair shop, just need to recruit trailer, otherwise can only tow by force, so will damage wheel hub, lose bigger.For this reason, people have thought that variety of way solves problem, as the disclosed novel patent of Chinese utility model patent communique " explosion-proof vacuum tire " (01251799.2), form by the inner tube of a tyre, cover tire, valve and steel ring, the inner tube of a tyre and cover tire respectively have independently valve, during use, earlier toward the inner tube air valve inflation, nausea mouth inflation outward again, interior air pressure and cover tire equate with air pressure between the inner tube of a tyre, and when cover tire was blown out, the inner tube of a tyre was losing between the cover tire and the inner tube of a tyre in the air pressure, under original atmospheric pressure, expand rapidly, keep running car.But this scheme is complex structure first, and two can the intact gas of very fast leakage when being punctured Tire ﹠ Tube by the iron nail class and difficult to move even one step.

The utility model content

The purpose of this utility model, be to provide a kind of can stop up the motor tire hole that punctured by the iron nail class automatically exempt from filling car vacuum tire.

For achieving the above object, the filling car vacuum tire of exempting from of the present utility model is characterized in that: at the inside face of tire, be stained with a transparent silica gel (also claiming glass cement) leakproof and exempt to mend layer, exempting to mend laminar surface in leakproof is equalizing press layer.

Described equalizing press layer is that nylon wire or plastics rack add plastic sheeting.

When normal operation, because air pressure is identical in the tire, add the equalizing press layer effect of nylon wire or plastics rack everywhere, the inwall that the transparent silica gel (also claiming glass cement) with big viscosity sticks to tire forms an internal layer, and it is in heaps can not flow under gravity; When vehicle tyre was punctured by sharp shaped material, the viscose glue with big viscosity can be filled up hole automatically, prevented gas leakage.

The beneficial effects of the utility model are: because this later-modelly exempts from filling car vacuum tire, but auto-mending is punctured hole by sharp shaped material, does not need heat cure, does not hinder carcass, convenient, fast, material-saving, economy.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the cross-sectional schematic of this new embodiment 1 structure.

Fig. 2 is the A-A line cutaway view along Fig. 1.

Fig. 3 is the cross-sectional schematic of this new embodiment 2 structures.

Fig. 4 is the B-B line cutaway view along Fig. 3.

Among the figure: 1 tire, 2 leakproofs exempt to mend layer, 3 equalizing press layers, 4 plastic sheetings.

The specific embodiment

Can see that from Fig. 1,2 the utility model embodiment 1 exempts from filling car vacuum tire,, be stained with silica gel or the leakproof of silicone glass cement and exempt to mend layer 2 that exempting to mend laminar surface in leakproof is nylon wire equalizing press layer 3 at the inside face of tire 1.

Fig. 3, embodiment 2 shown in Figure 4, equalizing press layer with exempt to mend interlayer plastic sheeting 4 arranged.

Equalizing press layer also plastic wire shelf structure corresponding with the tire inner chamber, that certain rigidity is arranged add plastic sheeting 4.

The mending-leakage process as described above.

Claims

1, a kind of filling car vacuum tire of exempting from is characterized in that: the inside face in tire (1), and be stained with silica gel or the leakproof of silicone glass cement and exempt to mend layer (2), exempting to mend laminar surface in leakproof is equalizing press layer (3).

2, the filling car vacuum tire of exempting from according to claim 1, it is characterized in that: described equalizing press layer (3) is a nylon wire.

3, the filling car vacuum tire of exempting from according to claim 2 is characterized in that: described nylon wire equalizing press layer (3) and leakproof are exempted to mend between layer (2) and are added with plastic sheeting (4).

4, the filling car vacuum tire of exempting from according to claim 1, it is characterized in that: described equalizing press layer (3) adds plastic sheeting (4) for the plastic wire shelf structure.
