Novel inflation-free tire

Abstract

The invention discloses a inflation-free tire which mainly comprises an inner ring pipe, a net, a positioning device and a filling material; the inner ring pipe is a ring which is provided with a hollow chamber and is made from a tubular product, the positioning device is encircled outside the inner ring pipe, a certain clearance is formed between the positioning device and the outer surface of the inner ring pipe, the net is covered on the positioning device, and the filling material is filled outside the inner ring pipe and wraps the net and the positioning device together. Because the tubular inner ring pipe is arranged inside the filling material of rubber and the like, the inner ring pipe can reduce the use of the filling material of the rubber and the like, the weight of the tire is reduced, heat generated in the running process of the tire can be emitted out by a conduit arranged on the inner ring pipe, a cooling medium also can be further injected into the inner ring pipe by the conduit, and the heat-radiation effect of the tire is better.

Description

technical field [0001] The invention relates to a vehicle tire, in particular to a non-pneumatic tire. Background technique [0002] Present vehicle tire mostly all is to fill inner tube with air, has harder and wear-resistant rubber cover tire outside the inner tube. Because this kind of pneumatic tire is easy to age, easy to be punctured, nailed, easy to explode at high temperature, and is extremely afraid of bullets. Engineering vehicles (such as: loaders, trucks, excavators and other large equipment), mobile construction machinery and equipment and some special vehicles (such as: wheeled armored vehicles), as well as the needs of operating vehicles under harsh road conditions. For this reason, the industry has designed solid tires, but solid tires have defects such as heavy weight, poor elasticity, high cost, and difficult heat dissipation. Although pneumatic tires and solid tires have their own advantages, neither is ideal. Contents of the invention [0003] The ob...

Problems solved by technology

Because this kind of pneumatic tire is easy to age, easy to be punctured, nailed, and easy to explode at high temperature, it is extremely afraid of bullets. If any of the above situations occurs, the vehicle cannot run normally. Engineering vehicles (such as: loaders, trucks, excavators and other large equipment), mobile construction machinery and equipment and some special vehicles (such as: wheeled armored vehicles), and the demand for vehicles operating under harsh road conditions

For this reason, the industry has designed solid tires, but solid tires have defects such as heavy weight, poor elasticity, high cost, and difficulty in heat dissipation.
