Abstract

The utility model discloses a new device of a puncturing proof pneumatic tyre, which is suitable for high speed vehicles of automobiles, electric cars, tractors, engineering automobiles, airplanes, etc. The new device of a puncturing proof pneumatic tyre is formed by gluing a tread, a metal puncturing proof layer and a tyre body. When the tread of a tyre is punctured accidentally, the tyre body is protected by the metal puncturing proof layer to cause the tyre not to leak air.

Description

Anti-pricked air-inflation tyre

The utility model relates to a kind of improved air-inflation tyre, is applicable on the high speed vehicle such as automobile, electric car, trac., engineering truck and aircraft, particularly runs into accidental causes such as iron nail, glass under steam and puncture glass not.

Existing tire is made up of cover tire, the inner tube of a tyre and rim strip three parts, tubeless tires is also arranged, cover tire is the main body of tire, be divided into cord-rubber combined structure and no cord structure two big classes, it contacts with the road surface, bear inflation pressure and vehicle load, stop the inflation after expansion, transmitting tractive power, steering effort and braking force.But can not protect accidental causes such as Yin Cizha to cause tire flat, can not safety traffic.

In order to address this problem, relevant researchist is just studying this tire always since the tire invention.As adopt the bellows wall inner tube of a tyre, double-tube tire, filling sponge tire, puncture-proof tyre etc.Adopt the bellows wall inner tube of a tyre, the inner compressing stress that produces during inflation makes perforation place by tight jam-packed.Travel but can not guarantee to be pierced tire safety effectively, tire weight is increased, give birth to heat and improve, produce complicated.Double-tube tire and filling sponge tire, though obtained practical application, raw materials consumption is many, cost is high, and incompatibility is run at high speed, and application limitation is very big.Though puncture-proof tyre is also used,, need the time spent often can not play a role, so also not quite suitable because leakproofing material is perishable under steam.Therefore from middle nineteen sixties, people have carried out a large amount of research to the safety tyre of the modern operating needs of real adaptation.Common feature all is the section of the tubeless end, and adopts lubricant mostly in the tire, and needs to be equipped with special wheel rim.After accidental causes such as tire Yin Cizha cause gas leakage, also can only continue to use safely a segment distance.

The purpose of this utility model provides a kind of improved tire, and it can guarantee accidental cause and sting and do not wear tire, guarantees safety traffic and eliminates the trouble of carrying spare tire.

The purpose of this utility model is achieved in that the metal antipricking layer that combines after in tread of tyre and carcass gluing one deck is by spring steel and sheet steel processing protecting carcass, has reached that tire is not pierced, vapor tight purpose.The present invention is simple in structure, and is easy to use.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a kind of concrete constructional drawing of the present utility model.

Fig. 2 is the antipricking layer front view by metal material processing of the present utility model.

Fig. 3 is an antipricking layer left view of the present utility model.

Fig. 4 is the partial enlarged drawing of antipricking layer front view of the present utility model.

Fig. 5 is the partial enlarged drawing of antipricking layer left view of the present utility model.

With reference to Fig. 1, the metal antipricking layer (2) with favorable elasticity is bonded in carcass (1) and the tyre surface (3) by polymeric isocyanate glue, also can use the strong higher adhesive of peel strength of metal and rubber adhesion power here.

For higher moving velocity and driving comfort are preferably arranged, and tire after the inflation and tire in rolling process, the complicated deformation that produces is to be processed into chain link (4) stage clip (5) and U-shaped jump ring (6) assembles by sheet steel and spring steel with reference to Fig. 2, Fig. 3, Fig. 4, Fig. 5 metal antipricking layer.When tire will protect carcass (1) not to be pierced because of accidental cause punctures tyre surface (3) metal antipricking layer (2).

Claims

A kind of anti-pricked air-inflation tyre is characterized in that in tread of tyre and carcass, has a metal antipricking layer of being made up of chain link (4) stage clip (5) and U type jump ring (6), and antipricking layer and carcass and tyre surface are bonded as one.
