Abstract

The invention relates to a tire which is applied to motor vehicles and non-motor vehicles, and is particularly applied to automobile tires, off-the-road tires, mining mechanical tires and the like. The tire is characterized by firstly making TPU into TPU foamed elastic closed-pore particles, putting the TPU foamed elastic closed-pore particles into a space formed by a cover tire and a wheel rim of a wheel, pasting a plurality of TPU foamed elastic closed-pore particles together by virtue of an adhesive or a surface hot melting process, fully filling the space formed by the cover tire and the wheel rim with the TPU foamed elastic closed-pore particles, reserving gaps between the TPU foamed elastic closed-pore particles so as to form an inner tire elastic support body, wherein the inner tire elastic support body is in a solid ring shape, and the cover tire, the wheel rim and the inner tire elastic support body form a whole body. The tire just needs to be locally inflated or does not need to be inflated; and the tire has the characteristics of burst resistance, puncture resistance, no maintenance and long service life.

Description

technical field [0001] The invention relates to a tire used for motor vehicles and non-motor vehicles, especially for automobile tires, engineering machinery tires, mining machinery tires and the like. Background technique [0002] At present, there are many types of non-pneumatic tires at home and abroad, most of which are solid structures, and the solid interior is filled with plastic, rubber, polyurethane elastomer or composite elastomer, etc., to achieve the function of non-inflation. This type of tire is currently mainly used for engineering machinery tires, mining machinery tires, etc., and is rarely used for automobile tires. [0003] The patent "Pneumatic-Free Plastic Tire" (patent number: ZL200820173551.8) discloses a tire whose outer tire is a mixture of rubber powder generated from waste rubber and granules generated from waste plastic. Life is difficult to guarantee. [0004] The patent "a tire with a composite elastomer filling the inner cavity and its prepara...
