Abstract

The utility model relates to a non-flat-after-burst safety motor vehicle tyre, which comprises an inner tyre which is embedded in an outer tyre, wherein, a protective tyre is arranged in the inner tyre and inosculated with the inner tyre; the wall of the protective tyre is provided with a check-valve. The utility model has the advantage of simple structure, effectively prevents a vehicle body from inclining after the tyre explodes and consequently avoids occurrence of the phenomenon that the tyre of a running vehicle explodes to cause that the vehicle is broken and the people die, etc.

Description

The self-propelled vehicle not flat safety tyre of blowing out

The utility model relates to a kind of motor tire.

The use tire of current mobility car generally is that inflatable inner tube is set in the cover, yet, easily produce when this tire exists long-distance running at high speed and blow out, owing to blow out, moving velocity is higher, the vehicle body immediate inclination, car body is out of control, easily causes major traffic accidents such as car crash.

It is a kind of simple in structure that the purpose of this utility model is to provide, and when the automobile high-speed long-distance running was blown out, car body was difficult for bevelled driving safety failure-free tire.

In order to achieve the above object, the technical solution adopted in the utility model is: tire 2 in the embedding in the cover 1, in protection tire 3 is arranged in the tire 2 and with interior tire kissing and, the protection tyre sidewall is provided with non-return valve 4.

The utility model has the advantages that:

Simple in structure, self-propelled vehicle is long-distance, when running at high speed tyre explosion, car body is difficult for tilting, and prevents that effectively the car crash major traffic accidents from taking place.

Description of drawings:

Fig. 1 is the tire scheme drawing;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 3 as can be known, the utility model comprises in the cover 1 tire 2 in the embedding, in protection tire 3 is arranged in the tire 2 and with interior tire kissing and, the protection tyre sidewall is provided with non-return valve 4.

Described protection tire 3 is provided with adhesive spots 5 more than at least three with interior wheel joint.

Principle of work:

The utility model is during to inflation of tire; inner tube of a tyre air inlet; the protection tire is by the non-return valve air inlet; make the protection tire also simultaneously by top off; self-propelled vehicle is because the high speed long-distance running then produces when blowing out; stagnating to be stored in protects the interior gas of tire can force non-return valve cock shutoff protection tire non-return valve to be given vent to anger; make the protection the form of the foetus become a tire that equates with the preceding pressure of blowing out; automobile tyre is blown out moment; protection tire top off, so self-propelled vehicle travels as usual prevents effectively because after self-propelled vehicle blows out; the car body run-off the straight has avoided the overturning phenomenon to take place.

Claims (2)

1, a kind of self-propelled vehicle not flat safety tyre of blowing out; form by cover, interior tire; it is characterized in that: tire (2) in the interior embedding of cover (1), protection tire (3) be arranged in the interior tire (2) and with interior tire kissing and, the protection tyre sidewall is provided with non-return valve (4).
