Abstract

The invention discloses a double -layer flat-proof tire. The tire comprises an outer wall, two side walls and inner isolating walls, wherein the upper ends of the two side walls and the inner isolating walls are connected with the outer wall into a whole body; the inner isolating walls divide a chamber formed by the outer wall and the two side walls into a plurality of cavities; the lower end surfaces of the two side walls and the inner isolating walls are all coiled on ring slots corresponding to hubs; the tire and the hubs form different closed air chambers which are isolated from one another; the inner isolating walls are parallel with the two side walls; the inner side walls symmetrically divides the chamber formed by the two side walls and the outer wall into three cavities; the ring slots in the hubs are in one-to-one correspondence with cavities on the tire; air filling nozzles are formed in all the ring slots, so that air inflation or air releasing is convenient. The essence of the tire is to implicitly divide one tire into a plurality of tires on the premise that the boundary dimension and wheel performance are not changed, and when one air chamber is cracked, the other air chambers can still operate normally, the whole tire cannot be collapsed, vehicle can be normally driven for a certain distance, and a driver has sufficient time to find the problem and take measures, so that traffic accidents are effectively avoided, and life and property safety is protected.

Description

Double-layer explosion-proof tire

Technical field

The present invention is a kind of double-layer explosion-proof tire.

Background technology

In the vehicle travel process such as automobile, the vehicle accident caused that bursts suddenly due to tire happens occasionally, and causes serious harm to the lives and properties of people.The most only one of which chamber of existing automobile tire, is namely surrounded a cavity by tire and wheel hub, is filled with air, it does not have the inner tube of a tyre in chamber.When tire pressure is relatively big, or when being violently shaken suddenly, tyre sidewall will burst, and deflatings of whole tire moment even departs from wheel hub, and car is disequilibrium immediately, cause car to be turned on one's side or before turn over.Here it is the main cause that tyre break has an accident.

Existing tire only one of which chamber, if can not change structure, during tyre break overturn be impossible to avoid.Only way improves tire quality exactly, it is to avoid walk uneven road.But garage's a thousand li, which has, and always smooth nothing serious that road allows you walk always, particularly by way of building site, township's material the or during path of mountain area, not only having hole has recessed, further encounters the hard things such as nail tyre puncture, and so on.Tyre break can not be avoided completely overturn accident is caused so only making an effort in tire material.It is necessary the structure of tire is improved.

Summary of the invention

For this; the present invention proposes a kind of double-layer explosion-proof tire; this tire is when running into tyre sidewall and damaging suddenly; tire will not whole collapse; still can normally travel stretch journey, allow driver have time enough to pinpoint the problems, gain time for re-type; thus being prevented effectively from the vehicle accidents such as overturning, protect the safety of life and property of driver and crew better.

This double-layer explosion-proof tire that the present invention proposes, it is characterized in that it is made up of outer wall, two side and endoseptum, two side and endoseptum upper end are all integrated with outer wall link, the cavity that outer wall and two side surround is separated into multiple chamber by endoseptum, two side and the lower surface of endoseptum all around hoop on the corresponding annular groove of wheel hub, tire surrounds from wheel hub and different completely cuts off mutually sealed gas chamber.

Endoseptum is parallel with two side.

Endoseptum is 1-5.

Endoseptum is set to two and is preferred, and now, the cavity that two side and outer wall surround is divided into three chambers symmetrically.

Annular groove on joined wheel hub and the chamber one_to_one corresponding on tire, each annular groove all has filling gas mouth, in order to inflated for deflated.

Outer wall, sidewall and endoseptum elastomeric material are made of one.

The essence of the present invention is exactly under the premise not changing overall dimensions and wheel performance, and an existing tire is impliedly divided into multiple tire.During manufacture, produce the wheel hub tire of correspondence respectively, in a conventional way by tire around hoop on wheel hub, allowing sidewall and endoseptum closely be affixed with the annular groove on wheel hub, after normotopia, inflate until reaching predetermined pressure toward each sealed gas chamber in.

Why the present invention is called that double-layer explosion-proof tire is based on each air chamber and all has two walls in left and right.

Air chamber and chamber are considered as synonym by the present invention.

It is characteristic of the invention that same tire has multiple air chamber independent mutually; the set of multiple tires in fact; when a wherein air chamber explosion; remaining air chamber can normal operation in the same old way, tire will not whole collapse, and still can normally travel stretch journey; driver is allowed to have time enough to pinpoint the problems; for taking the measures such as re-type to gain time, thus being prevented effectively from the vehicle accidents such as overturning, protect the safety of life and property of driver and crew better.

Accompanying drawing explanation

Fig. 1 is the structural representation (cross-sectional view) of the present invention.

In Fig. 1, the label of each several part is as follows:

1-outer wall；2-endoseptum；3-sidewall；4-middle chamber；5-side cavity；The 6-right side adds air nozzle；7-wheel hub；8-adds air nozzle；A 9-left side adds air nozzle.

Detailed description of the invention

The present invention is further illustrated below in conjunction with accompanying drawing and example.

Example 1 is as it is shown in figure 1, outer wall 1 and two side 3 are basically identical with existing tire.Two endoseptums 2 are parallel with two side, and the symmetry of tire is divided into middle chamber 4 and left and right Liang Ge side cavity 5 by it.

Being integrated as it has been described above, the upper end of two side and endoseptum links with outer wall, lower end forms opening and fits tightly banding with the ledge face of the water jacket of wheel hub 7 and inside groove respectively.The water jacket at two ends is each provided with a left side and adds air nozzle 9 and the right side adds air nozzle 6, middle inside groove adds air nozzle 8 in being provided with,. respectively add the structure of air nozzle and existing to add air nozzle identical, but respectively add air nozzle and be not necessarily arranged on the same plane of hub axis line, and on to facilitate the principle of aerating to arrange.

The structure of wheel hub is the same with the basic structure of the wheel hub of existing common wheel except changing except the structure of above-mentioned inside groove and water jacket.

The outside wall surface design of tire can have some to increase the concave tooth of frictional force as conventional tyre, and the thickness of sidewall and endoseptum suitably can increase and decrease according to the needs of different wheel.

As it has been described above, the quantity of endoseptum is 1-5, quantity more more means that independent chamber is more many, and the performance of runflat is more high, but too much endoseptum quantity necessarily increases the difficulty manufacturing and installing.So being advisable with 2 as shown in this example Fig. 1.Such tire chamber is separated into three chambers, middle one, each one of both sides.No matter therein which burst suddenly, other two all can normal operation, even if two chambers therein burst suddenly, all the other chambers also can normal operation certain time, keeping vehicle smooth-ride stretch journey, driver also has time enough to take corresponding safety measure.

Therefore, the double-layer explosion-proof tire of this three air chambers to exceed more than three times than the explosion-proof security of an existing common air-chamber tire.

Example 2, Guan Bi of individually being turned back in opposite directions in two endoseptum upper ends of example 1 so that it is upper end and outside wall portions leave certain gap, and all the other are constant, are thus equivalent to install a little tire in tire additional.During assembling, the cover that outer wall and two side surround, to wheel hub, is then enclosed within the outside of little tire and binds round on same wheel hub, after filling up gas respectively by little tire cuff again that first surrounded by endoseptum.The trouble-proof tire of this two-layer equation also has certain explosion-proof than conventional tyre, but less better compared with example 1 of globality, when cover tire bursts suddenly, little tire can support certain time, vehicle be also unlikely to rollover or before turn over, but vehicle has certain inclination to be inevitable, and safety is less better.

NM parts and label are described above.
