Abstract
The utility model discloses a partial filling type run-flat tire. The run-flat tire comprises a tread (1) and a left side wall and a right side wall (4) which adopt an integral structure with the tread (1); a retaining ring sealing opening (6) is formed at the inner end of the side wall (4), two isolation strips (3) are arranged in a cavity body encircled by the tread (1) and the side walls (4), one end of each isolation strip (3) is fixed, and the free ends of the two isolation strips (3) are mutually lapped; and an inflation pressure strip (5) filled with air is arranged in a space on one side of the isolation strip (3), and an explosion-proof endless strip (7) filled with small balls (2) is arranged in a space on the other side of the isolation strip (3). After foreign matter is inserted into the tire, the explosion-proof endless strip is not generally pierced, the influence to the use of the tire is little affected, or only a small amount of filled small balls are punctured, the inflation pressure strip is avoided from the phenomenon of air leakage, and the tire can be still used; and the inflation pressure strip on the side adjacent to the retaining ring sealing opening is filled with air, so as to ensure that the tire has necessary shock absorbing properties.
Description
(1), technical field
The utility model relates to a kind of trouble-proof tire, is specifically related to a kind of trouble-proof tire that has charges.It is mainly used in the abominable occasion of the explosive environment of tire, as mine, metallurgy, open-air engineering construction, aircraft, battlefield vehicle etc., also can be used for full size vehiclees such as coml passenger and freight car.
(2), background technology
Present tire has two kinds, and a kind of is the air-inflation tyre that does not have charges, and a kind of is solid non-inflatable tyre.Airtyred advantage is that damping property is good, and shortcoming is to blow out easily; The advantage of non-inflatable tyre is can not blow out, and shortcoming is that damping property is bad.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of part fill-type trouble-proof tire is provided, and forms explosion-proof endless belt and inflation pressor areas in tire, makes tire both be not easy to blow out, and has certain damping performance again.
The technical scheme that the utility model adopted is as follows:
A kind of part fill-type trouble-proof tire, comprise tyre surface and with the tyre surface one about two tyre sidewalls, tyre sidewall the inner has the back-up ring close mouth, it is characterized in that: in the cavity that tyre surface and tyre sidewall surround, be provided with two insulation strips, one end of each insulation strip is fixed, and the free end of two insulation strips overlaps mutually; The space of insulation strip one side is that the inflation that is filled with gas adds pressure zone, and the space of insulation strip opposite side is the explosion-proof endless belt of filling up the filling bead.
One of them concrete scheme is: two insulation strips are separately fixed on the inwall of two tyre sidewalls; Space between insulation strip and the back-up ring close mouth adds pressure zone for inflation, and the space between insulation strip and the tyre surface is explosion-proof endless belt.
Wherein another concrete scheme is: also comprise the inner tube of a tyre that is installed within tyre surface and the tyre sidewall, two insulation strips are separately fixed on the both sides inwall of the inner tube of a tyre.
Good effect of the present utility model is: be filled to the tread of tyre internal layer by rubber or other particles filled thing with certain particle size, form an explosion-proof endless belt.Foreign matter penetrates generally can not prick behind the tire wears this explosion-proof endless belt, little to the use influence of tire, or it is bad to have only minority filling bead to be pricked, and inflation of tire adds pressure zone and can not leak gas, and tire still can use.Add near the inflation of back-up ring close mouth one side and to charge into gas in the pressure zone, guaranteed that tire has necessary damping performance.
(4), description of drawings
Fig. 1 is the structural representation of first embodiment of the utility model.
Fig. 2 is the structural representation of second embodiment of the utility model.
(5), the specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Example one
As Fig. 1, present embodiment comprise tyre surface 1 and with tyre surface 1 one about two tyre sidewalls 4, tyre sidewall 4 the inners have back-up ring close mouth 6.The free end that is fixed with an insulation strip 3, two insulation strips 3 on the inwall of two tyre sidewalls 4 respectively overlaps mutually.Space between insulation strip 3 and the back-up ring close mouth 6 is filled with gas for inflation adds pressure zone 5.Space between insulation strip 3 and the tyre surface 1 is explosion-proof endless belt 7, wherein fills up filling bead 2.
Example two
As Fig. 2, present embodiment comprise tyre surface 1 and with tyre surface 1 one about two tyre sidewalls 4, tyre sidewall 4 the inners have back-up ring close mouth 6, also comprise the inner tube of a tyre 8 that is installed within tyre surface 1 and the tyre sidewall 4.
The free end that is fixed with an insulation strip 3, two insulation strips 3 on the inwall of the both sides of the inner tube of a tyre 8 respectively overlaps mutually.The inner tube of a tyre space of insulation strip 3 one sides is filled with gas for inflation adds pressure zone 5.The inner tube of a tyre space of insulation strip 3 opposite sides is explosion-proof endless belt 7, wherein fills up filling bead 2.Described inflation adds pressure zone 5 near back-up ring close mouth 6 one sides, and described explosion-proof endless belt 7 is near tyre surface 1 one sides.
Among above-mentioned two embodiment, 2 fens series of filling bead according to the vehicle difference, is made the pressure difference, and general diameter is between 1-30mm.Filling bead 2 is the rubber-like High molecular material, such as elastomeric material.
Filling bead 2 can be a hollow ball, under tire working air pressure or be a bit larger tham tire working pressure by air pressure environment and issue infusion and become.Filling bead 2 can also be a solid sphere.
For environmental demands, the rubber granule manufacturing that the filling bead 2 that is adopted preferably adopts the waste old fragmentation to make.
Claims (3)
1. part fill-type trouble-proof tire, comprise tyre surface (1) and with tyre surface (1) one about two tyre sidewalls (4), tyre sidewall (4) the inner has back-up ring close mouth (6), it is characterized in that: in the cavity that tyre surface (1) and tyre sidewall (4) surround, be provided with two insulation strips (3), one end of each insulation strip (3) is fixed, and the free end of two insulation strips (3) overlaps mutually; The space of insulation strip (3) one sides is that the inflation that is filled with gas adds pressure zone (5), and the space of insulation strip (3) opposite side is for filling up the explosion-proof endless belt (7) of filling bead (2).
