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.

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 improves the heat dispersion of tire, prevents inside phenomenon of gathering heat, burning one's heart to prolong its life.

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

The tire comprises a tire tread and tire sidewalls, wherein the two sides of the tire tread are respectively connected to the tire sidewalls on the left side and the right side, the tire sidewalls are inwards sunken to form a plurality of grooves, the grooves on the tire sidewalls on the two sides are arranged in a staggered mode, and the groove on one tire sidewall is located between two grooves on the other tire sidewall in the radial direction of the tire.

the two ends of the groove on one of the tire side are respectively communicated with the two adjacent grooves on the other tire side.

The grooves are uniformly distributed on the tire side at equal intervals along the circumferential direction of the tire.

A circular cavity is formed in the tire, the cavity and the tire are concentric, and the grooves are communicated with the cavity.

A support is fitted in the cavity, which support matches the shape of the cavity.

The supporting piece is made of metal.

After the structure and the method are adopted, in the practical application process, when the tire runs, air enters one end of the groove and flows out from the other end of the groove, so that heat accumulated in the tire is taken away, the phenomena of heat accumulation and core burning in the tire are avoided, the heat dissipation performance of the tire is improved, and the service life of the tire is prolonged. When the grooves on one side are communicated with the grooves on the other side, the heat dissipation performance is further improved.

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.

For convenience of description, the following terms "upper", "lower", "left" and "right" are consistent with the vertical and horizontal directions of the attached drawings, but do not limit the structure of the present invention.

As shown in fig. 1 to 7, in order to achieve the first embodiment of the present invention, a tire includes a tread 1 and sidewalls 2, and both sides of the tread 1 are connected to the sidewalls 2 on both sides. The sidewall 2 is inwards sunken to form a plurality of grooves 3; as shown in fig. 6, the grooves 3 on the two sidewalls 2 are arranged alternately, the groove 3 on one sidewall 2 is located between two grooves 3 'on the other sidewall 2' in the radial direction of the tire, and in order to further improve the heat dissipation performance, two ends of the groove 3 on one sidewall 2 are respectively communicated with two adjacent grooves 3 'on the other sidewall 2'.

The contact area between the tire and the air is increased by the grooves 3, and in the advancing process of the tire, the tire is in contact with more air, and the heat accumulated in the tire is dissipated, so that the problems of internal heat accumulation and core burning are solved, and the heat dissipation performance of the tire is improved; only the end part of the groove 3 on one side is communicated with the groove 3 'on the other side, but the groove 3 is communicated with the other side 2' from one side 2 of the groove, so that air flows to the other side from one side of the tire, the heat dissipation performance is further improved, and meanwhile, the bearing performance of the tire is not influenced.

The grooves 3 are uniformly distributed on the sidewall 2 at equal intervals along the circumferential direction of the tire, and the uniform equal-interval grooving on the sidewall 2 can ensure the stability of the bearing performance of the tire and realize beautiful appearance.

As shown in fig. 8, a second embodiment of the present invention is different from the first embodiment in that: a circular cavity 4 is formed inside the tire, the cavity 4 is concentric with the tire, and the grooves 3 are communicated with the cavity 4, so that the circulation range of air inside the tire is further enlarged, and the heat dissipation performance is improved.

As shown in fig. 9, in the second embodiment, the cavity 4 of the tire may be fitted with a support 5, and the support 5 matches the shape of the cavity 4, which may enhance the load-bearing performance of the tire. The support piece 5 is made of metal and different from the material of the tire, and the problem of internal heat accumulation can be avoided, so that the service life of the tire is prolonged.

Through the structure, the utility model discloses at practical application's in-process, when the tire marchd, the air got into the recess 3 of one side to flow out by the recess 3 ' of opposite side, take away the heat of the inside gathering of tire, avoided the inside phenomenon of gathering heat, burning one's heart of tire, improved the heat dispersion of tire, thereby prolonged the life of tire.

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.
