Embodiment Construction

[0014] figure 1 , figure 2 , image 3 Middle mark: 1-tread, 2-carcass, 3-rubber tube, 4-fiber rope or steel wire rope, 5-radiation hole.

[0015] As shown in the figure, first take two or more high-strength fiber ropes or steel wire ropes and set them in the tire mold on the centrifugal molding machine, such as bicycle tires, children's tires, electric tires, rickshaw tires, motorcycle tires and other small tires, to set High-strength fiber ropes are suitable, forklift tires, battery tires, car tires and other large tires should be equipped with steel wire ropes, and then according to the structural design requirements of different types of tires, fix two or more pre-made rubber tubes on the tires. In the mold, close the mold, start the centrifugal molding machine, inject the prepared polyurethane liquid raw material into the centrifugal molding machine according to the designed amount, turn off the rotary switch of the centrifuge, and wait for 10-30 minutes for the tire in...

Abstract

An environment protection type non-inflation polyurethane tyre is composed of the surface and hollow body of tyre, which is made up of antiwear elastic polyurethane rubber through pouring and centrifugal shaping, and the core consisting of 2-3 rubber tubes and more than two high-strength fibre cables or steel wire cables.

Description

Technical field: [0001] The invention relates to an air-free tire, in particular to an environment-friendly air-free polyurethane tire. Background technique: [0002] The air-free tire is a new type of safe tire that does not need to be inflated, is not afraid of punctures, and will not blow out. [0003] At present, although there are many invention patents for air-free tires at home and abroad, most of them have heavy weight, poor elasticity, and laborious riding due to the lack of feasible innovations in tire technical structure, manufacturing materials and manufacturing processes. , high energy consumption, large internal heat generation, high cost of raw materials, and defects such as sliding, swinging, and instability of tires during vehicle running, so it is difficult to be accepted by consumers, and it has been difficult to popularize and apply so far. Invention content: [0004] Technical problem to be solved: [0005] The purpose of the present invention is to ...
