Abstract

The main principle of the invention is to change the air in the vacuum tire into an elastic entity with a certain shape at ordinary times, and when the rubber tire is worn or aged or punctured by external force, the rubber tire is provided with the elastic entity with a certain shape inside, so that the elasticity and the shape can be kept, and the normal running of the vehicle can not be influenced, thereby preventing the tire burst problem in the running process.

Description

Explosion-proof tyre

Technical Field

The invention is suitable for the function of preventing tire burst of the tires of vehicles such as bicycles, motorcycles, automobiles and the like in the using process.

Background

In daily life, the situation that the tire is leaked or even blown out when a vehicle is static or running is often encountered, particularly, the situation that the tire is leaked or blown out when the vehicle runs at a high speed brings potential safety hazards to drivers, and property loss and personal injury are caused to the society. The common tires in the market are provided with inner tubes and vacuum tires without inner tubes, and the main factors causing air leakage or tire burst are the aging or abrasion of tire rubber or the cutting of tire rubber by sharp substances, and the like, so that the air in the tires is released due to pressure, and the driving is influenced. The invention mainly changes the air in the tire into a solid substance with certain elasticity, and even if the tire rubber is aged or abraded or cut by a sharp substance, the tire rubber can keep a certain shape to continue running, thereby solving the potential safety hazard and property loss of tire leakage or tire burst. The invention is characterized in that the tire and the hub are filled with elastic solid matters, so that the shape of the tire is better maintained, and the tire can be maintained to run at a certain high speed even if the rubber outside the tire is damaged.

Disclosure of Invention

The invention mainly changes the air in the tire into elastic solid with certain shape, the main material of the elastic solid is eva composite material at present, and the elastic solid can also be elastic solid with fixed shape made of other materials. The main components comprise a hub, an elastic solid with fixed form made of composite materials such as eva and the like, and a rubber tire, wherein the elastic solid with fixed form and the rubber tire are combined into a whole, the hub is made into two parts for good installation, the first part is a main body (a main body hub), the elastic solid with fixed form such as eva and the like is put into the rubber tire or combined with the rubber tire through plastic spraying or hot pressing, then the elastic solid with fixed form such as eva and the like is put into the main body hub of the first part, the two parts of hubs can be made into various forms such as a separating form, an embedded form, a spiral form and the like, then the second part of hubs are combined into a whole through combining, rotating, tenon-and-mortise forms and the like, so that the two hubs are not easy to be separated together, and then are installed on the main body hub through screws, thus the hubs are better ensured not easy to be separated in the driving process, the elasticity entity need make certain thickness, and the thickness requirement is to exceed rubber tire thickness and can not let rubber tire expose in the wheel hub outside when combining with wheel hub, has both guaranteed the perfect laminating of rubber tire and wheel hub, guarantees again that rubber tire has certain internal pressure, makes rubber tire keep certain elasticity, makes the elasticity entity that its rubber tire and materials such as eva made can not produce the displacement to the three unites two into one, constitutes the run-flat tire.

Detailed Description

Drawings

Fig. 1 is an important component part of a run flat tire: rubber tyre, elastic body, wheel hub. Fig. 2 is a design of a split hub. FIG. 3 is a spiral rotary composite hub design. Fig. 4 is a drop-in hub molding.

FIG. 1 illustrates

Fig. 1 is an important component part of a run flat tire: rubber tire, elastic entity, wheel hub. The rubber tire mainly has the functions of wear resistance, pressure resistance and the like, the elastic entity replaces air in the hollow tire, deformation is not easy to occur, certain shape and elasticity are kept under the condition that the rubber tire on the outer side is damaged, and dangerous conditions of a driver caused by tire burst and the like are prevented. The rubber tire and the elastic entity can be manufactured respectively, or the rubber tire can be manufactured firstly and then integrated into a whole through plastic spraying, hot pressing or gluing, and the elastic entity is mainly made of eva composite materials at present, for example, the elastic entity made of eva composite materials for insoles or soles is used, so that certain form can be achieved, and certain elasticity can be guaranteed due to the fact that the elastic entity is not easy to deform. Other composite materials can be selected as long as certain form and elasticity can be ensured. In order to better install the combination of the rubber tire and the elastic entity on the hub, the hub needs to be separated, the combination of the rubber tire and the elastic entity is installed on the main hub, then the auxiliary hub is combined together through a certain shape (such as embedded type, separated type and spiral type), and finally the auxiliary hub is fixed by screws. The rubber tire, the elastic entity and the hub are combined into a whole to form a set of explosion-proof tire.

FIG. 2 illustrates

Fig. 2 is a design of a split hub. The separation and combination modes of the hub can be two types: one is to uniformly separate an integral hub and then combine them together and fix them with screws, and the other is to separate them beside the hub and then combine them together and fix them with screws. The screws can be uniformly fixed on the hub support and can also be uniformly fixed on a hub beside, so that the fixed form of the hub in the driving process is ensured, and powerful support of the rubber tire and the elastic entity is provided.

FIG. 3 illustrates

FIG. 3 is a spiral rotary composite hub design. Fig. 3 is a view of separating an integral hub, wherein the inner side surface of one hub is made into a screw shape, such as the hub marked as C in the figure, and the outer side surface of the other hub is made into a nut shape, such as the hub marked as D in the figure, then the two are combined into a whole through rotation, and finally the two are uniformly fixed on the outer side surface of a wheel rim (the inner side of the wheel rim facing to the rubber tire and the elastic body) through screws. The fixing screw is made to be fixed in proper length, so that the inner side surface cannot be broken through, and the purpose of fixing the inner side surface and the outer side surface is achieved. The hub C can be made into a thin outer part and a thick inner part (the circle close to the hub marked as C is inner), and the hub D can also be made into a thin outer part and a thick inner part (the circle close to the hub marked as D is inner), so that the hub D can be completely rotated to the bottom and completely attached, and the whole horizontal thickness can be kept the same. The hub supporting column can be arranged on any one of the hub entities C and D, and only one of the hub entities C and D can be selected, and the specific direction depends on the outer side face of the vehicle hub.

FIG. 4 illustrates

Fig. 4 is a drop-in hub molding. Fig. 4 is that an integral wheel hub is separated, and two tenon-and-mortise structures are respectively made, so that the integral wheel hub is mutually attached, the side, contacting the rubber tire and the elastic entity, of the wheel hub is smooth and flat, and then the two tenon-and-mortise structures are fixed by screws. The mortise and tenon structure is mainly placed on the outer side of the wheel rim (facing the inner side of the rubber tire and the elastic entity wheel rim), and the inner side of the wheel rim is kept smooth and flat. And finally, uniformly fixing the wheel hub steel ring on the outer tenon-and-mortise structure surface through screws. The fixed screw needs to be made into fixed suitable length, is unlikely to puncture the inner side face of the wheel hub steel ring, and only plays the purpose of fixing the inner side face and the outer side face.
