Description

Composite anti-puncture anti-explosion tire

technical field

The utility model belongs to the anti-explosion and anti-puncture design in the technical field of auto parts, and relates to a composite anti-puncture and anti-explosion tire.

Background technique

Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on the metal hub, it can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. However, if the tire is pierced by iron nails or other sharp objects and it is not punctured temporarily, it will leak air, which will cause a puncture. A puncture refers to a tire that suddenly loses air and deflates in a very short period of time (generally less than 0.1 second). A flat tire is one of the most frequent accidents in the summer. Most of them are caused by the improper maintenance of the tires by the car owner, and some of them are caused by the excessive width of the tire sidewall, which is easy to scratch and damage. Relevant statistics show that 10% of traffic accidents on expressways are caused by tire failures, and one of them, tire blowout, accounts for more than 70% of the total number of accidents caused by tire failures. Therefore, how to prevent tire from blowing out after being punctured is an important problem to be solved in the technical field of tires.

Utility model content

The technical problem to be solved by the utility model is to provide a composite anti-puncture and anti-explosion tire aiming at the deficiency of the existing car tire anti-puncture and anti-explosion problem.

The composite anti-puncture explosion-proof tire in the utility model comprises a first rubber layer, a second rubber layer, an anti-puncture layer, an air-filled layer, and a wheel hub, and is characterized in that: the explosion-proof layer is placed between the first rubber layer and the second rubber layer. In the middle of the rubber layer, an inflatable air-filled layer is arranged between the second rubber layer and the hub.

The anti-punching layer is adjacent to the inflatable layer, the anti-punching layer is placed on the outer ring, and the inflatable layer is placed on the inner ring. When the tire is pierced by iron nails or other sharp objects, it is not easy to penetrate the inflatable layer, thereby effectively protecting the tire. The safety of the inflatable layer can avoid the occurrence of tire blowout.

The structure of the anti-tie layer is in the form of honeycomb briquettes or columnar air struts and columnar springs, which can play a certain buffering role when the car encounters steps or obstacles when driving, reducing tire wear and extending the length of the tire. service life.

The surface of the first rubber layer is provided with textures, which increase the gripping performance of the tire when the tire is in contact with the ground.

The width of the sidewall of the air layer can be further reduced, which can effectively reduce the friction damage of the sidewall of the tire when the driving road is narrow and there are steps next to it.

Description of drawings

Fig. 1 is a schematic diagram of the axial side of the utility model.

Detailed ways

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

The reference signs in the drawings of the description include: the first rubber layer (1), the second rubber layer (2), the anti-punching layer (3), the air-inflating layer (4), and the hub (5).

Embodiment such as described in accompanying drawing 1:

The composite anti-puncture explosion-proof tire of the utility model is composed of a first rubber layer (1), a second rubber layer (2), an anti-puncture layer (3), an air-filled layer (4) and a wheel hub (5). The first rubber layer (1) is located on the surface of the anti-punching layer (3), the anti-punching layer (3) covers the second rubber layer (2), the second rubber layer (2) covers the inflatable layer (4), and the inflatable layer (4) Wrap the hub (5). Textures are provided on the surface of the first rubber layer (1) to increase the frictional force between the tire and the ground. The structure of the anti-punching layer (3) is honeycomb-like structure, which can effectively prevent iron nails or other sharp objects from penetrating the tire and avoid the occurrence of tire blowout; at the same time, it can play a certain buffering role when encountering steps and reduce tire wear , prolong the service life of the tire.

Compared with the existing tires, the utility model has the advantage that since the tire is provided with an anti-tie layer, when iron nails or other sharp objects are encountered during driving, the iron nails or other sharp objects will pierce the anti-tack layer On the top, it will not penetrate the inflatable layer, thus avoiding the occurrence of tire blowout.

What is described above is only the embodiment of the utility model, and common knowledge such as the specific structure and characteristic known in the scheme is not described too much here. It should be pointed out that for those skilled in the art, under the premise of not departing from the structure of the utility model, some deformations and improvements can also be made, and these should also be regarded as the protection scope of the utility model, and these will not affect the utility model. Effects of novel implementations and utility of patents. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification may be used to interpret the content of the claims.
