Abstract
The utility model relates to an anti-explosion tire free of inflating, which is mainly applied in various kinds of wheeled vehicle such as car, motorcycle, bicycle and airplane. The utility model is mainly characterized in that: the utility model adopts the method that the wheel boss compresses the closed-cell elastic foaming material that is completed by one-off closed-cell foam in the tire inner cavity to replace the traditional high-pressure air way and prevent the tire from piercing or the tire burst accident caused by the overheated tire . In addition, during the service life of the tire, the tire is free of inflating so as to greatly increase the reliability and facility and effectively decrease the occurrences of traffic safety accidents.
Description
Affiliated technical field
The utility model relates to a kind of trouble-proof tire of exempting to inflate, and is mainly used in as various wheeled transportation meanss such as automobile, motor bike, bicycle and aircrafts.
Background technology
Along with China's rapid economic development, communications and transportation is busy day by day, and various major traffic accidents are of common occurrence, has caused very big loss for the national economy and the people's lives and properties.Analyze these accident causations, owing to the very big ratio that occupies of tyre explosion initiation.Though multiple trouble-proof tire product is arranged both at home and abroad, they are inadequate supporting and running one segment distance of energy after blowing out just, is not trouble-proof tire truly, and because cost is high, is difficult to popularize.
Summary of the invention
What the utility model proposes a kind ofly exempts to inflate trouble-proof tire, has solved the problems referred to above preferably.Not only make tire in service life, avoid inflation, and the possibility of tyre explosion is reduced greatly, and cost is little than the conventional tyre increase, is trouble-proof tire truly.
The scheme that the invention for solving the technical problem adopted is:
Cover tire adopts tubeless tires, to tyre cavity and be installed in enclosure space filling flexible foaming material and foaming agent mixed liquor between the cylindrical die of bore portion in the tire, finish through disposable closed pore foaming, the flexible foaming material can adopt polyurethane or other plastics or rubber; The circumference outer contour of cylindrical die is identical in tire endoporus scope with the circumference of hub outer contour, and less than circumference of hub outer contour diameter, its difference is calculated by maximum load per tyre, the intensity of closed pore flexible foaming material, modulus of elasticity, inside tires normal pressure the circumference outer contour diameter of cylindrical die in tire endoporus scope.When the tire that machines uses the special tyre mounting tools to be installed on the wheel hub, because the internal orifice dimension of the closed pore flexible foaming material of tyre cavity is less than the wheel hub external diameter, therefore produce elastic deformation and form the interior pressure of tire, has identical effect with tire filling high pressure air, when tire is stabbed, just destroyed the minute bubble very among a small circle of the closed pore flexible foaming material of tyre cavity, very slight to the influence of tire single-piece, do not influence cruising, more can not blow out.When tire because of temperature the high or adstante febre that travels for a long time, because the closed pore flexible foaming material and the wheel hub closed contact of tyre cavity, improved the heat dispersion of tire, so the interior pressure of tire can not significantly improve yet, and in the service life of tire, avoid inflation.
The beneficial effects of the utility model are on the basis that increases limited cost, adopt the way of the closed pore flexible foaming material of tyre cavity being compressed to substitute traditional high pressure air, prevent the accident of blowing out that tire is stabbed or caused because of tire is overheated.Owing to carry out disposable closed pore foaming at tyre cavity, thereby make in the tire, integral body of outer formation, the intensity and the reliability of tire all are greatly improved, basically can avoid the accident of blowing out, and in the service life of tire, avoid inflation, safety and convenience have been improved greatly, can effectively reduce the generation of great safety traffic accident, and because the proportion of closed pore flexible foaming material is lighter, increase to tire weight is not obvious, can not increase considerably fuel oil consumption, simultaneously, because closed pore flexible foaming material has better elastic, also can not have a significant impact travelling comfort.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the elevation profile constructional drawing of the utility model and mould embodiment.
Fig. 2 is the elevation profile constructional drawing that the utility model is installed to wheel hub embodiment.
1. tubeless tiress among the figure, 2. closed pore flexible foaming material, 3. mould, 4. wheel hub.
The specific embodiment
The tubeless tires (1) that has machined is installed in the mould (3), flexible foaming material and foaming agent mixed liquor are injected the enclosure space that is formed by tubeless tires (1) inner chamber and mould (3), foam through closed pore, form closed pore flexible foaming material (2), be installed on the wheel hub (4) with special tool at last.
Claims (2)
1, a kind ofly exempt to inflate trouble-proof tire, it is characterized in that: cover tire is a tubeless tires, tyre cavity filling closed pore flexible foaming material, closed pore flexible foaming material at tire endoporus scope inner periphery outer contour diameter less than the tubeless tires diameter of bore.
2, a kind of trouble-proof tire of exempting to inflate according to claim 1, it is characterized in that: the flexible foaming material can adopt polyurethane or other plastics or rubber.
