Abstract
The invention discloses an elastic light inflation-free tire which comprises an outer tire and an elastic light inner tire, and is characterized in that the elastic light inner tire is composed of elastic materials such as elastic polyurea materials or rubber and the like and elastic light materials; the elastic polyurea material wraps each elastic polyurethane material or other elastic light materials with strong recovery ability, and the shape of the elastic light materials is honeycomb-shaped or other uniform shapes to manufacture the elastic light inner tube; the shape and size of the elastic light material are determined according to the size and bearing pressure of the tire, or the elastic polyurea material is uniformly sprayed after the integral molding; according to the requirement, the outer tire is manufactured on the basis of the formed elastic light inner tire by utilizing the existing process, and can also be arranged in the outer tire appearing in the market; the invention can realize inflation-free, has good elasticity, light weight, durability, tire burst prevention, tire puncture resistance, wide application range and comfortable use.
Description
Technical Field
The invention relates to the field of tire manufacturing, in particular to an elastic light inflation-free tire.
Background
With the development of times, the living standard of people is improved, various vehicles using tires are continuously emerged, for the tires needing inflation, tire deflation causes much trouble to people, and the tire deflation causes the greatest hidden danger of tire explosion; the existing solid tire has heavy weight, almost no elasticity and poor comfort level, and can only be used for low-speed running vehicles such as bicycles, electric vehicles, loaders and the like.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and designs an elastic light-weight non-inflatable tire which can be used in high and low speed vehicles, is free from inflation and explosion-proof, light in weight, good in elasticity and durable.
The invention adopts the technical scheme that the elastic light inflation-free tire comprises an outer tire and an elastic light inner tire, and is characterized in that the elastic light inner tire is composed of an elastic polyurea material and an elastic light material; the elastic polyurea material wraps each elastic polyurethane material or other elastic light materials with strong recovery energy, the shape of the elastic light materials is a honeycomb shape or other uniform three-dimensional shapes, the elastic light materials are used for replacing air, the elastic polyurea materials or rubber and other elastic materials are used as bag bodies to wrap the elastic light materials to form a state of air bags, and the air bags are tightly connected to form the elastic light inner tube; the shape and size of the elastic light material are determined according to the size and bearing pressure of a tire, or the elastic polyurea material is uniformly sprayed after the integral molding; and manufacturing the outer tire on the basis of the formed elastic light inner tire by utilizing the existing process according to the requirement.
The invention can realize inflation-free, has good elasticity, light weight, durability, tire burst prevention, tire puncture resistance, wide application range and comfort.
Drawings
FIG. 1 is a side sectional view of a tire, in which 1 a thick black line is shown as an outer tire, 2 a thin black line is shown as an elastic material such as polyurea, and 3 a light elastic material; fig. 2 is a sectional view of the tire, in which 1 a thick black line is shown as an outer tire, 2 a thin black line is shown as an elastic material such as polyurea, and 3 a light elastic material.
Detailed Description
A preferred embodiment of the invention is to shape the said elastic lightweight material, such as the lightweight polyurethane material used in the soles of existing sports shoes, into the shape of the said inelastic lightweight inner tube, which is then axially divided into annular sheets, or radially divided into pieces, the specific shape and size are determined according to the size of the tire and the pressure required to be borne, making a honeycomb or other shaped grid from said elastomeric polyurea material according to said sheet-like volume, filling the elastic light material in the grids, then spraying and sealing the grids, forming an independent air bag state for each grid, then combining each formed sheet-shaped object or the independent small air bags into strips and the like to synthesize the elastic light inner tube, the outer tire is manufactured on the basis of the elastic light inner tire, or the elastic light inner tire is installed in an outer tire appearing in the existing market.
Claims (6)
