Abstract

The explosion-proof tyre for vehicle consists of cover type and inner tyre tube. The inner tyre consists of several independent inner tubes communicated via valve. In case that some inner tube is pierced or burst to become normal pressure, the valve will be closed owing to the pressure difference making the rolling stop normally in middle position move to block the valve opening, while the other inner tubes operate normally to ensure the normal work of the tyre. The present invention has the features of being safe, reliable and convenient in replacing.

Description

Explosion-proof self-saving tyre

Explosion-proof self-saving tyre relates to vehicle and makes the field.

Tire in the past is the only tire of a courage, in case ground leakage loss or the explosion of being taken by surprise, gently then vehicle can not sat, heavy then out of control bringing about frightful disaster.

The objective of the invention is to design a kind of can be when blowing out emergency self-saving, and still can keep the tire of normal operation function.

The present invention is made up of the cover tire and the inner tube of a tyre.The inner tube of a tyre is made up of several relatively independent inner bags.Inner bag is the capsule of a two ends band vent.Be connected in series by a logical valve that closes between each inner bag.Logical to close valve be a tubular body, and plug and normotopia spring are formed by rolling.The diameter of rolling plug is less than the internal diameter that leads in the chamber of closing valve, greater than the logical internal diameter that closes valve two ends mouth piece.The inner wall outside of two ends mouth piece is equipped with a normotopia spring that has certain elastic force.The plug that rolls is positioned at its normotopia spring force middle part in one's power, both sides.In case explosion appears in certain inner bag, its pressurized air totally and coupled logically closed valve the good courage pressure of end is interdependent in addition, and the restriction that causing the plug that rolls to break through the normotopia spring is pushed up to mouth piece internal orifice place its shutoff, isolated with outside atmospheric air, thus kept the normal operation of most of inner bags.

The present invention uses aerodynamic principle dexterously, having broken the old inner tube of a tyre constitutes, removed the trouble and worry of blowing out, leaking tire that to expect and to be taken by surprise of long-term puzzlement car circle, in case have the advantages that still to keep the basic operation function of vehicle after blowing out.

Fig. 1 is a transparent view of the present invention;

Fig. 2 is the logical section working diagram that valve is in opening state that closes of the present invention;

Fig. 3 is the logical section working diagram that valve is in closed state that closes of the present invention.

Embodiment: present embodiment is made up of the cover tire 1 and the inner tube of a tyre.The inner tube of a tyre is made up of several relatively independent inner bags 2.Logically close valve 5 and be connected in series by one between inner bag 2 and the inner bag 2, form the loop of a closure.Be shaped on the Inflation door 4 that a pressurized air enters among the inner bag 2.Logical to close valve 5 be a tubular body 5, and plug 6 and normotopia spring 7 are formed by rolling.The diameter of rolling plug 6 is less than the logical internal diameter that closes valve 5 inner chambers 8, greater than the logical internal diameter that closes valve 5 two ends mouth pieces 9.Inboards in the mouth piece 9 are equipped with a normotopia spring 7 that has certain elastic force.The plug 6 that rolls is positioned at normotopia spring 7 elastic force middle part in one's power, 8 both sides, chamber.Be shaped on the place-limited edge 10 of a normotopia spring 7 on the inboard tube wall in the mouth piece 9.

Its principle of work is: when extraneous air is compressed enter the inner bag 2 of ganging up mutually after owing to enter the expansion resilience of gas and the effect of normotopia spring 7, the logical rolling plug 6 that closes in the valve 5 is in medium position basically, logically closes valve 5 and is in opening state; And in case 2 explosions of certain inner bag are arranged, its in-to-in pressurized air totally and still exists with its logical interior pressure of good courage that valve 5 links to each other 2 that closes; Because the differential pressure action that valve 5 is inside and outside, the elastic force restriction that the plug 6 that causes rolling is broken through normotopia springs 7 is pushed to end in addition, and is with the internal orifice shutoff of mouth piece 9, isolated with extraneous normal pressure.The normal operation that has so kept most of inner bags 2 is lost the basic operation function that one is not enough to influence whole tire, sues and labours for escaping danger at least and has won the quality time.

As long as the logical valve 5 that closes that will make in advance when dispatching from the factory is connected in series with each inner bag 2; Be that a hole charges and discharge gas equally during use, repair also convenient and swiftly, be as good as with well-established law.
