Abstract
The utility model discloses an explosion-proof automobile tyre. Both Ends of an inner tyre are closed and tubular; the inner side of an outer tyre is totally closed and is only provided with an elliptical hole; a steel ring is provided with another elliptical hole, the size of which is same with the elliptical hole of the outer tyre, and the positions are corresponding; the elliptical hole of the outer tyre is provided with a cover which is positioned between the inner tyre and the outer tyre, and the cover is also provided with a hole which can be penetrated by an air nozzle. Glue can be added between the cover and the elliptical hole of the outer tyre to seal. The cover and the air nozzle can be fixedly connected. The utility model has the advantages that the utility model can avoid occurrence of the tyre explosion situation, can effectively prevent foreign objects, such as sands, etc. being clamped between the inner tyre and the outer tyre, and can prolong the service life of the inner tyre; the utility model is used conveniently, and the carrying capacity can also be increased.
Description
One, technical field
The utility model relates to motor tire, relates in particular to a kind of runflat motor tire.
Two, background technology
Motor tire comprises the car wheel covering and the inner tube of a tyre, at present, motor tyre casing ringwise, still open the inboard, the inner tube of a tyre is an annular air-pocket.Automobile is when running at high speed, if the inner tube of a tyre is punctured, inner tube of a tyre gas can be let out to the greatest extent moment, and this is still to open because of cover tire, does not stop when inner tube of a tyre gas is gone out.When blowing out, the often not anxious reaction of driver can not in time be braked, and can lose direction or cause and overturn.Chinese patent ZL 200320126055.4 discloses a kind of inner tube, and carcass is made by rubber, and valve is housed on the carcass, carcass is the tubular body of closed at both ends, in other words, is open circuited annulus, the advantage of this patented technology is: tire patching is convenient, does not need to dismantle cover tire.But if this inner tube of a tyre is punctured, inner tube of a tyre gas also can be let out to the greatest extent moment, does not have the runflat function.
Three, summary of the invention
The purpose of this utility model provides a kind of runflat motor tire.
The utility model runflat motor tire, comprise steel ring, rubbery cover tyre, and the tubular rubber inner tube of a tyre of closed at both ends, valve is arranged on the inner tube of a tyre, be positioned at the end of the inner tube of a tyre, be characterized in: described rubbery cover tyre inboard is totally-enclosed, only offer an elliptical aperture, offer one and described cover tire elliptical aperture elliptical aperture of a size on the described steel ring, and the position is corresponding, described cover tire elliptical aperture is provided with a lid, and described lid is provided with the hole that described valve can pass on the described lid between the inner tube of a tyre and cover tire.
In the such scheme, described lid and the sealing of described cover tire elliptical aperture glue.
In the such scheme, described lid is captiveed joint with described valve.
The utility model, only can lose heart from cut when the inner tube of a tyre is punctured because cover tire also adopts enclosed construction, the longer duration that loses heart, and the driver can in time find abnormal tyre, slows down, brakes.The new advantage of this practicality is: the situation of can avoiding blowing out takes place, and prevents that effectively foreign matter such as sand is clipped between the inner tube of a tyre and the cover tire, prolongs the service life of the inner tube of a tyre, and is easy to use, can also improve load-carrying capacity.
Four, description of drawings
Described in detail below in conjunction with the utility model embodiment accompanying drawing:
Fig. 1 is the utility model decomposing schematic representation.
Five, the specific embodiment
As shown in Figure 1, the utility model runflat motor tire comprises steel ring 1, rubbery cover tyre 2, and the tubular rubber inner tube of a tyre 3 of closed at both ends, and valve 4 is arranged on the inner tube of a tyre 3, is positioned at the end of the inner tube of a tyre 3.Rubbery cover tyre 2 is inboard totally-enclosed, only offers an elliptical aperture 5, offers an elliptical aperture 6 on the steel ring 1, elliptical aperture 5 and elliptical aperture 6 the same sizes, and the position is corresponding, and cover tire elliptical aperture 5 is provided with a lid 7, lid 7 is provided with the hole 8 that valve 4 can pass on the lid 7 between the inner tube of a tyre 3 and cover tire 2.Also can between lid 7 and elliptical aperture 5, seal by gluing, lid 7 and valve 4 are fixed on simultaneously.
During use, earlier cover tire 2 is installed on the steel ring 1, elliptical aperture 5 and elliptical aperture 6 align, then, the inner tube of a tyre 3 is passed through elliptical aperture 6,5, fill in the cover tire 2, valve 4 is retained in elliptical aperture 5,6 places, valve 4 passes the hole 8 on the lid 7, lid 7 is filled in the cover tire 2 from elliptical aperture 5 and elliptical aperture 6, gluing sealing between lid 7 and elliptical aperture 5 is after gluing, to inner tube of a tyre aerating.
Claims (3)
1, a kind of runflat motor tire, comprise steel ring, rubbery cover tyre, and the tubular rubber inner tube of a tyre of closed at both ends, valve is arranged on the inner tube of a tyre, be positioned at the end of the inner tube of a tyre, it is characterized in that: described rubbery cover tyre inboard is totally-enclosed, only offer an elliptical aperture, offer one and described cover tire elliptical aperture elliptical aperture of a size on the described steel ring, and the position is corresponding, described cover tire elliptical aperture is provided with a lid, and described lid is provided with the hole that described valve can pass on the described lid between the inner tube of a tyre and cover tire.
2, runflat motor tire according to claim 1 is characterized in that: described lid and the sealing of described cover tire elliptical aperture glue.
