Abstract
The utility model discloses a vehicle tyre, which is composed of an inner tube and a cover tyre used for bundling the inner tube. The inner tube is a hard circular supporter which is matching with the chamber of the cover tyre. The utility model has the advantages of non-inflation, convenient use, high strength, etc.
Description
Technical field
The utility model relates to vehicle tyre.
Background technology
The middle-size and small-size non-power-driven vehicle of prior art, the tire that uses as hand barrow etc. mostly is inflatable tire, though have characteristics such as in light weight, good springiness, exists except that the regular inflation of needs, also be afraid of defectives such as sharp-pointed object thorn, be shorter than cover tire the service life of the inner tube of a tyre greatly.The band tyre that also has a kind of employing to make in the tire that above-mentioned prior art is used with a kind of material such as plastics etc., such tire does not have the branch of Tire ﹠ Tube, though have characteristics such as intensity height, anti-bundle, life-span length, lack the elasticity that the inflatable tire cover tire is had, effective utilization is not satisfactory.
Summary of the invention
Task of the present invention is to provide a kind of non-inflated wheel for vehicle tire.
Its technical solution is:
The utility model vehicle tyre, it has the cover tire of the inner tube of a tyre and the parcel inner tube of a tyre, and the above-mentioned inner tube of a tyre is the hard annular support suitable with the cover tire inner chamber.
Above-mentioned annular support can be polyurethane foam formula structure.
Above-mentioned cover tire can form annular opening port between relative two limit portions of inner ring surface.
The part at the corresponding annular opening port of the inner ring surface of above-mentioned annular support place can slightly protrude in annular opening port.
The utility model adopts hard annular support such as polyurethane foam formula supporter, can avoid inflation first, and is easy to use; Second Tire ﹠ Tube can adopt different materials to make, and makes cover tire possess the cover tire characteristic of conventional tire; Adopt polyurethane foam formula structure, have in light weight, consumptive material is few, the intensity advantages of higher, can keep good in-use performance.The inner ring surface of above-mentioned cover tire is offered annular opening port, can check and touch the appropriate section of annular support by annular opening port, the material of check annular support when being convenient to the user and choosing, simultaneously, can directly select the cover tire of conventional tire during making for use, reduce the tire cost of manufacture, enhance productivity.The part at the corresponding annular opening port of the inner ring surface of above-mentioned supporter place can slightly protrude in annular opening port, on the basis that can adapt to the rim assembling, also can save the consumptive material of cover tire, reduces the cost of manufacture of cover tire.
Description of drawings
Fig. 1 is a kind of embodiment structural representation of the utility model.
Fig. 2 is a carcass section drawing among Fig. 1.
Below in conjunction with accompanying drawing the utility model is described:
The specific embodiment
Referring to Fig. 1, Fig. 2, the inner tube of a tyre of the present utility model is a polyurethane foam formula annular support 2, the supporter 2 outer cover tires 1 of wrapping up in, form annular opening port between the cover tire 1 inner ring surface two opposite edges portion 11,12, the part 21 at the corresponding annular opening port of the inner ring surface of supporter 2 place slightly protrudes in annular opening port.
It can be made in the following way, select traditional Outer Tyre as cover tire 1 of the present utility model, this cover tire is placed the peripheral hardware mould, to offer again fill ester hole (mouth) in establish the interior round mouth that mould is inserted cover tire 1, by interior outer mold the cover tire sealing is limited, and liquid polyurethane is charged in the inner chamber of cover tire by the interior ester hole of filling of establishing mould, curing molding becomes polyurethane foam formula annular support 2.
The utility model also can adopt following frame mode except that adopting the said structure mode, one can be, and its cover tire inner ring surface also can adopt enclosed construction, and the intercommunicating pore (mouth) of establishing mould in the correspondence and filling the ester hole is set on inner ring surface; It two can be, and cover tire adopts following structure, after the cover tire inner chamber is provided with annular support, just contacts in relative two limit portions of cover tire inner ring surface.
