Abstract

The utility model discloses a non-inflatable tyre. In the non-inflatable tyre, an elastic support is composed of spiral steel wires and a pressure spring; the spiral steel wires are arranged in a plurality of unconnected inner cavities arranged in a tyre body; the tyre body is fixedly clamped by an inner and an outer steel plates; pressure springs are uniformly distributed in the radial direction of the circumference on the inner steel plate; the bottom of the pressure spring is provided with a pressure regulating bolt which can regulate the outward supporting force of the tyre body in the radial direction. The utility model has the advantages of stable structure, large supporting force, large elastic force, wear resistance and long service life and can be used for any vehicles using tyres for walking.

Description

Non-inflatable tyre

The utility model relates to a kind of tire, but particularly relates to a kind of pressure-adjusting type non-inflatable tyre of making skeleton with elastomeric material.

Traditional tire all is made up of inside and outside tire, inner tube of a tyre inflation, but being subjected to external force easily, this tire causes gas leakage, or valve fault and flat tire makes troubles to use, for avoiding this trouble, people have released a kind of, are 91220090 non-inflatable tyre as application number, though it can not worry to be pricked gas leakage, but still exist bearing force less, should not bear the deficiency of heavy load.

The purpose of this utility model is, for overcoming the deficiency of prior art, provides a kind of bearing force big, anti abrasive non-inflatable tyre.

Following mode can realize the utility model:

Non-inflatable tyre comprises rubber tyre body, resilient mounting, constitute resilient mounting by spiral wire and pressure spring, the unconnected inner chamber of rubber tyre body inner periphery multiple tracks permutation inter, spiral wire is installed in the chamber, inside and outside steel plate clamping carcass, carcass both sides projection embeds in the groove of inside and outside steel plate, circumference radial equipartition pressure spring on the interior steel plate, establish a top board between the edge in pressure spring top and the carcass, the mutual snapping of top board, regulator bolts is arranged at the pressure spring bottom.

Near the carcass surface, uniform steel wire.

At the tooth-in position of carcass, be equipped with the steel wire of one group of circle.

The utility model Stability Analysis of Structures, firm, high resilience, stressed even, removed airtyred inflation, pricked the worry of leaking gas and blowing out, bearing force is big, can adjust used resilient mounting according to the load carrying ability of vehicle, wear-resistant, be airtyred many times service life.

Embodiment:

In rubber tyre body 1, the discrete inner chamber 2 in circumferential arrangement three roads, surface of internal cavity is provided with spiral groove, spiral wire 3 is installed in the groove, interior steel plate 4 and outer steel plate 10 clamping carcasses 1, carcass both sides projection 11 embeds in the groove of inside and outside steel plate, the circumference 45 well-distributed pressure springs 6 of radially being separated by on the interior steel plate 4, between the edge top board 5 is arranged in pressure spring 6 tops and the carcass 1, the mutual snapping in top board two ends, supporting plate 8 is arranged at the bottom of pressure spring 6, and regulator bolts 9 withstands on the supporting plate 8, near carcass 1 surface, the uniform steel wire 12 of 15 radians of being separated by, be equipped with one group of round wire 13 at carcass 1 tooth-in position circumference, in, outer steel plate 4 and 10 is provided with fixing threaded

hole

15 and 14, when making rubber tyre body 1, spiral wire 3, steel wire 12, original shape steel wire 13 is together gone into mould with the tire base, make moulding, regulator bolts 9 can be reconciled the outside support power of carcass, to adapt to different load carrying ability automotive uses.

Claims
