Abstract

The invention provides an aeration-free tire and belongs to the technical field of tires. The aeration-free tire has the advantages of structure stability, light weight and excellent crushing resistance. The aeration-free tire comprises a tread (1), a base rubber (2) and an elastic support (3) in turn from exterior to interior along the radial direction of the tire; a pattern can be arranged on the tread (1); the base rubber (2) is integrally vulcanized with the tread; the elastic support (3) has a function of supporting the tread; the elastic support (3) comprises an outer pressure-bearing ring (31), an inner pressure-bearing ring (34) and a middle support (32); the outer pressure-bearing ring (31) is glued with the base rubber (2); the inner pressure-bearing ring (34) is in contact with a rim (4); the middle support (32) is located between the outer pressure-bearing ring (31) and the middle support (32); the middle support (32) is composed of a plurality of pressure-bearing components (33) which are densely arrayed; each of the pressure-bearing components (33) is composed of a first bending component (331) and a second bending component (332) which have multiple sections of arcs and are symmetrically arranged along the axis on the radial direction.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a non-pneumatic tire. Background technique [0002] The widely used tires with tubes and tubeless tires are pneumatic tires. The principle is to inject compressed air into the inner cavity of the tire to load the tire. The biggest safety hazard is that once the tire is punctured or scratched by a sharp object, It is very easy to have air leakage, or even a tire blowout, resulting in a safety accident. The patent application with the application number 201510246208.6 discloses a non-inflatable hollow tire. The five buffer air cavities inside the tire carcass and the left and right rectangular buffer air cavities arranged at the adjacent position between the tire toe and the carcass form a structure that can ensure that the tire The elastic supporting rib system with reliable working elasticity ensures that the non-inflatable hollow tire has the conventional elastic ability and defo...
