Problems solved by technology

All of the above tires have disadvantages. Pneumatic tires will blow out or run flat, which will easily cause traffic accidents or damage the tires and delay time due to lack of air, causing a lot of trouble. Curved spring tires are heavy, core tires have no elasticity, and the cushioning reduces Poor vibration

Embodiment Construction

[0011] In Fig. 1, the outer surface of the annular elastic outer steel ring (3) is bonded with a layer of rubber as a buffer layer (4). The inner steel ring (5) is welded with the assembly nut (2) and the cord cord (6) to wrap the annular elastic outer steel ring (3) and the inner steel ring (5) into one body, and the equidistant space between the two steel rings, A cavity is naturally formed. The annular elastic outer steel ring (3) is subjected to the centripetal tension of the left and right sidewall cord cords (6), and the annular elastic outer steel ring (3) forms an elastic circular bow. Round bow, when there is no external force centripetal action, the annular elastic outer steel ring only has its own circular bow tension on the entire tire cord cord (6) The tensile fatigue force is very small, only when the tire part is under centripetal pressure, the cord cord Only then will the corresponding resistance pull force be produced. Tension and tension support each other ...

Abstract

The invention discloses a air-charging free tire with an empty cavity; an outer annular elastic steel ring, an inner annular steel ring, an annular opening expansion ring, rubber cord fabrics and a pressure-regulating top thread are arranged in the body of the tire; the structural principle of the invention is as follows: the inner annular steel ring and the outer inner annular steel ring are wrapped by the rubber cord fabrics; an equal distance space preserved between the two annular steel rings forms the empty cavity. The outer annular elastic steel ring is strained by the centripetal pull of the cord fabric for forming an elastic round arc for supporting the car load. When the pressure of the tire is insufficient, the annular opening expansion ring is pushed out to the outside by the pressure-regulating top thread and the cord fabrics in the inner ring of the tire is externally bulged by the pushing force of the expansion ring for straining the cord fabrics at the left side and theright side of the tire to tighten and increase the pressure. The air-charging free has the advantages of low fatigue of the cord fabrics, long service life, non tyre burst, pricking resistance, broadapplication range from heavy-duty cars to children bicycles; the air-charging free tire can replace a air charging tire and a solid tire.

Description

[0001] The technical field [0002] The invention relates to a tire, in particular to an air-free cavity tire. Background technique [0003] As far as the inventor knows, the various tires sold on the market and the tires used on existing various vehicles are mostly pneumatic tires, and only a few heavy loaders and military artillery vehicles use solid core tires. Said to have a kind of air-free tire that many balloons fill tire cavity, another kind of patent No. is that the elastic tire of ZL00204750.0 is designed by myself, also has a kind of solid core tire filled with elastic plastic. All of the above tires have disadvantages. Pneumatic tires will blow out or run flat, which will easily cause traffic accidents or damage the tires and delay time due to lack of air, causing a lot of trouble. Curved spring tires are heavy, core tires have no elasticity, and the cushioning reduces Poor vibration. Contents of the invention [0004] The technical solution adopted by the pres...
