Technical Field

The invention relates to a tire, in particular to a tire with a heat dissipation wind tunnel.

Background

A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. The metal wheel hub is usually arranged on a metal wheel hub, can support a vehicle body, buffers external impact, realizes contact with a road surface and ensures the driving performance of a vehicle. Tires are often used under complex and severe conditions, which are subjected to various deformations, loads, forces and high and low temperature effects during driving, and therefore must have high load-bearing, traction, cushioning and heat dissipation properties.

In order to dissipate heat generated by a tire in the running process, a heat dissipation structure is usually arranged on the tire, and the conventional heat dissipation structures are mainly divided into two types, namely, the tire adopts a small flower on a tire shoulder part, so that materials at the tire shoulder part and a tire bead part of the tire are reduced, the heat generation of the tire shoulder part and the tire bead part is reduced, the heat dissipation of the tire is improved, the early damage of the tire is reduced, and the service life of the tire is prolonged; secondly, after the tire is vulcanized, holes are drilled at the tire shoulder part and the tire bead part of the tire manually or automatically, so that the heat dissipation and the gas exhaust in the tire are facilitated in the using process of the tire, the early damage of the tire is reduced, and the service life of the tire is prolonged.

In the two modes, the tire with the small patterns added on the tire shoulder has a poor heat dissipation effect, the tire production process is increased by manually or automatically punching the tire shoulder part and the tire bead part, the problems of missing of punching, missing of detection, difficulty in controlling the punching depth and the like exist, and a technical scheme capable of solving the problems is urgently needed.

Disclosure of Invention

In order to solve the problems, the invention provides the tire with the heat dissipation wind tunnel and the inner cavity isolation type structure, and the heat dissipation and gas exhaust effects of the tire are improved.

The technical scheme adopted by the invention is as follows: a tire with heat dissipation wind tunnels comprises a tire body, wherein the tire body is provided with a plurality of heat dissipation wind tunnels formed by vulcanization.

Further, the plurality of heat dissipation wind tunnels are arranged at a tire shoulder part of the tire body, a tire bead part of the tire body, or a shoulder part and a tire bead part of the tire body.

Furthermore, an included angle a between the heat dissipation wind tunnel arranged at the tire shoulder part and a horizontal shaft of the tire body is-25 degrees to 25 degrees.

Furthermore, an included angle b between the heat dissipation wind tunnel arranged at the tire bead position and the normal line of the tire side at the position of the heat dissipation wind tunnel is-5 degrees to 5 degrees.

Furthermore, the plurality of heat dissipation wind tunnels are arranged at the tire shoulder position or the tire bead position in an annular arrangement structure around the axis of the tire body.

Preferably, the shape of the heat dissipation wind tunnel is circular.

Further, the heat dissipation wind tunnel extends from the surface of the tire body to a position close to the carcass layer.

Compared with the prior art, the invention has the following beneficial effects:

the tire with the heat dissipation wind tunnel is vulcanized at the tire shoulder and the tire bead to form the heat dissipation wind tunnel, so that the heat dissipation and exhaust effects of the tire can be effectively improved, the early damage of the tire is reduced, the service life of the tire is prolonged, and the tire with the heat dissipation wind tunnel is simple and convenient in processing technology and convenient to produce.
