Description

tyre for vehicle

Technical Field

The utility model relates to a tire field especially indicates a tire.

Background

Tires are ground-rolling annular elastic rubber products assembled on various vehicles or machines, and are generally mounted on metal rims to support vehicle bodies, cushion external impacts, achieve contact with road surfaces, and ensure the driving performance of the vehicles. Tires are often used under complex and severe conditions, which are subjected to various deformations, loads, forces and high and low temperature effects during running, and therefore must have high load-bearing, traction and cushioning properties. At the same time, high wear resistance and flexibility, as well as low rolling resistance and heat dissipation, are also required.

The existing pneumatic tire and solid tire are common tires, have strong durability and bearing property and have the defect of leaking light gas once a hole is broken. In order to solve the problem of air leakage of the tire, a solid tire structure is developed in the industry, and the problem of air leakage is solved. However, the solid tire is mostly used for low-speed vehicles, because the solid tire continuously rolls on the ground when the solid tire runs at a high speed, continuous high-frequency deformation occurs inside the solid tire to generate a large amount of heat, because the tire is of a solid structure, the heat is gathered inside the tire and cannot be timely dispersed, and long-time running can cause hot melting of materials inside the solid tire, so that a heart burning phenomenon is generated, and the service life of the solid tire is influenced. And when the tire is used, only the tire surface is in contact with the ground, the deformation of the tire is limited, the generated ground holding force is limited, the effective utilization rate of tire materials is low, and the material waste and the cost are increased.

In view of this, the present designer has a deep conception on many defects and inconveniences caused by the above-mentioned structural design, and actively studies, improves, and tries to develop and design the present invention.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tire can improve the heat dispersion of tire and grab ground performance, realizes save material, reduction in production cost simultaneously.

In order to achieve the above purpose, the solution of the present invention is:

In the radial section of the tire, one end of the tire main body, which is positioned at the outer ring of the tire, is bent towards one side of the tire and extends to form an extension part, the extension part is arranged along the inner ring of the tire towards the outer ring direction, and the root of the extension part gradually deviates from the central line of the radial section of the tire main body towards the top end; the extension forms one turn in the circumferential direction of the tire.

The radial section of the extension part is arc-shaped.

The tire further comprises a fixing part used for connecting the tire main body and the wheel hub, and the fixing part is connected to one end, located on the inner ring of the tire, of the tire main body.

The fixing part is protruded towards one side of the tire to form a flange embedded in the wheel hub.

The flange and the extension are located on the same side of the tire.

After the structure is adopted, in the practical application process of the utility model, when the tire advances, the extension part is pressed and deformed, so as to realize the damping effect, increase the contact area between the tire and the ground and improve the ground gripping performance of the tire; the width of the middle part of the tire main body of the utility model is smaller than that of the existing solid tire, and the heat gathered at the middle part of the tire main body is easier to be radiated to both sides, thus improving the heat radiation performance; compared with the existing solid tire, the same contact area is realized, and the required volume is smaller, so that the material is saved and the production cost is reduced.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 3, a tire includes a tire main body 1. In the radial section of the tire, one end of the tire main body 1, which is positioned at the outer ring of the tire, is bent towards one side of the tire and extends to form an extension part 2, the extension part 2 is arranged along the inner ring of the tire towards the outer ring direction, and the root of the extension part 2 gradually deviates from the central line of the radial section of the tire main body 1 towards the top end; the extension 2 forms one turn in the circumferential direction of the tire. The extension 2 may be bent to some extent about the root of the extension 2.

The radial section of the extension part 2 is arc-shaped, so that the tire has better buffering performance.

The utility model discloses still including the fixed part 3 that is used for connecting tire main part 1 and wheel hub 5, this fixed part 3 is connected in the one end that tire main part 1 is located the tire inner circle. The fixing part 3 is protruded towards one side of the tire to form a flange 4 which is embedded in a limiting groove of a wheel hub 5; the flange 4 is located on the same side of the tire as the extension 2.

As shown in fig. 4, in the process of the tire running on the ground 6, the gravity borne by the tire is transmitted to the extension part 2 from the vehicle, the hub 5, the fixing part 3 and the tire main body 1, the extension part 2 is deformed under pressure, and the deformation process achieves the effect of shock absorption; the side surface of the extension part 2 is contacted with the ground 6, compared with the prior solid tire with the tread contacted with the ground 6, the contact area is increased, and therefore the ground gripping performance of the tire is improved; meanwhile, the width of the middle part of the tire main body 1 is smaller than that of the existing structure, so that heat gathered in the middle part of the tire main body 1 is easier to dissipate to two sides, the heat dissipation performance is improved, and the influence of internal heat gathering on the service life of the tire is reduced; because extension 2 can increase the area of contact of tire and ground 6, realize the same area of contact, the utility model discloses used tire material still less to can save material, reduction in production cost.

Through the structure, in the practical application process of the utility model, when the tire advances, the extension part 2 is pressed and deformed, so as to realize the damping effect, increase the contact area between the tire and the ground 6 and improve the ground gripping performance of the tire; the width of the middle part of the tire main body 1 of the utility model is smaller than that of the existing solid tire, the heat gathered at the middle part of the tire main body 1 is easier to be radiated to both sides, and the heat radiation performance is improved; compared with the existing solid tire, the same contact area is realized, and the required volume is smaller, so that the material is saved and the production cost is reduced.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
