Solid-tire-and-rim composite structure

Abstract

The invention discloses a solid-tire-and-rim composite structure. The solid-tire-and-rim composite structure comprises a tire, a rim for fixing the tire and steel wire rings in the tire, wherein the tire is divided into a tire face part, tire edge parts on the two sides and a tire lip part in contact with the rim. A plurality of axial heat dissipation holes and a plurality of radial heat dissipation holes are formed in a tire body, the axial heat dissipation holes are formed in the tire edge parts and extend to the interior of the tire body in the axial direction of the tire, the radial heat dissipation holes extend to the axis in the radial direction of the tire, and the radial heat dissipation holes are connected with the axial heat dissipation holes to form Arabic-number-seven-shaped through holes. By means of the solid-tire-and-rim composite structure in the technical scheme, air is led in through the radial heat dissipation holes, heat flow is led out through the axial heat dissipation holes, and therefore the optimal heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to a solid tire combination, in particular to a combined structure of a solid tire and a wheel rim. Background technique [0002] A solid tire is a solid carrier of an industrial vehicle that must withstand loads and travel for a long time. During use, due to the extrusion and creep of the rubber in the carcass of the solid tire, the rubber in the carcass is stressed and prone to damage. Heat, with the gradual increase of the temperature of the rubber compound, and the heat in the carcass compound is not easy to dissipate, it is easy to cause the carcass compound to melt under high temperature conditions, resulting in problems such as delamination, resulting in early damage to the tire. It affects the service life, so it is very important to solve the problem of tire heat generation. [0003] As a solution to the heat generation of the solid tire carcass, Patent Document 1 (CN200920137108.X) discloses a solid tire structure. The ...

Problems solved by technology

However, this method has the following problems: although part of the heat flow generated by the rubber in the solid tire carcass can be discharged through the heat dissipation holes to achieve a certain heat dissipation effect, the heat dissipation holes are semi-closed spaces, and air replacement cannot be generated in the holes. The air circulation is formed, so that a large amount of heat flow will be formed in the hole. Under the action of high temperature heat flow, the rubber in the hole will melt, and finally cause hole cracks until the tire is damaged early.
