Abstract

The utility model relates to a hollow steel wire meridian tyre without inflation, which is composed of tyre rubber, an inclined cross curtain cloth layer, a steel wire meridian wire layer and a tyre surface. The utility model is characterized in that the hollow part of the tyre without inflation is composed of a set of U-shaped uniformly-distributed coiled springs having two bending sides, and the set of coiled springs are arranged among two reinforced tyre bodies in the tyre or a plurality of inclined cross curtain cloth layers and then pressed with the steel wire meridian wire layer to form an entity. When the tyre rotates, the U-shaped coiled springs can bear loading pressure in turn. The tyre has the advantages of no prick, no tyre burst, rubber saving, no deformation, long service life, safe running, no need of maintenance, etc.

Description

The hollow steel wire meridian does not have air-inflation tyre

The utility model relates to a kind of nothing inflation radial wire cord tire.

At present, filled honeycomb rubber, poly-Ammonia foamed plastic, the isoelastic material of solid rubber in the no air-inflation tyre of producing both at home and abroad all adopts.The tire that above-mentioned all types of packing material is made all belongs to fill-type tyre.Above-mentioned fill-type tyre is during because of vehicle immobilization, and elastomeric material is subjected to exerting pressure for a long time, is easy to generate expendable distortion, and influence is travelled.When Vehicle Speed is very fast, as: surpass 50 kilometers/hour, inside stuffing can produce high heat under strong extruding, when temperature surpasses 130 ℃, rubber is decomposed, and causes tire to damage fast.

The purpose of this utility model is to provide a kind of hollow steel wire meridian not have air-inflation tyre.

The utility model is made up of carcass rubber, cross-ply, steel wire meridian twine layer and tyre surface; It is characterized in that: the hollow of tire does not have the inflation position to be made up of one group of uniform U type spring structure, and U type spring both sides are crooked snakelike shape; Described one group of U type spring is distributed between the two-layer or multilayer cross-ply of the reinforcement carcass in the tire, and two tops of U type spring outwards curve, and are stuck on two bead wire rings, and make it to be pressed into an integral body; When tyre rotation, U type spring vertically rolls, and bears load-carrying pressure successively in turn; The steel wire meridian twine layer that the hollow of being made up of described U type spring and cross-ply does not have injection section and its outer ring together is pressed in mutually in the rubber for tire, constitutes a composite monolithic tire.

Hollow steel wire meridian described in the utility model does not have air-inflation tyre and has following advantage: inner tube free is non-inflatable, be not afraid of bundle, do not blow out, save rubber and cord material, be difficult for because of weight is out of shape, long service life, driving safety reliably and not must be safeguarded.

The drawing explanation:

Fig. 1 is that hollow steel wire meridian described in the utility model does not have airtyred vertical cross-section cutaway view.

Embodiment of the present utility model sees accompanying drawing: wherein 1 is tire surface, the 2nd, and radial twine layer, the 3rd, inside and outside layer cross-ply, the 4th, U type spring, the 5th, bead wire ring.This hollow steel wire meridian does not have air-inflation tyre, and to manufacture step as follows: with flattening mill cord is pressed between the two layers of thin sheet rubber, by must diagonal cross angle cut standby.Spring is evenly blocked on special tool, and the peripheral spacing of described one group of U type spring can be below 10 millimeters.Press angular cross in the spring medial and lateral cutting out good calendering sheet rubber, evenly press two-layer.The apparent load size can be at the calendering lamella of the double number of spring outside increase.After the shaping machine compacting, press one deck sidewall face film in the spring outside.Press steel wire meridian twine layer and tread-rubber in the spring bottom at last.All after the compacting, eliminate the internal layer bubble, put into forming mould and carry out sulfidization molding, make finished product.

Claims

A kind of hollow steel wire meridian does not have air-inflation tyre, it is made up of carcass rubber, cross-ply, steel wire meridian twine layer and tyre surface, it is characterized in that: the hollow of tire does not have the inflation position to be made up of one group of uniform U type spring structure, and U type spring both sides are crooked snakelike shape; Described one group of U type spring is distributed between the two-layer or multilayer cross-ply of the reinforcement carcass in the tire, and two tops of U type spring outwards curve, and are stuck on two bead wire rings, and make it to be pressed into an integral body; When tyre rotation, U type spring vertically rolls, and bears load-carrying pressure successively in turn; The steel wire meridian twine layer that the hollow of being made up of described U type spring and cross-ply does not have injection section and its outer ring together is pressed in mutually in the rubber for tire, constitutes a composite monolithic tire.
