Separated safety run-flat spring tyre

Abstract

The invention relates to a separated safety run-flat spring tyre, and belongs to a rubber light industrial product. The separated safety run-flat spring tyre comprises a tyre casing outer side and a tyre rim matched with the tyre casing outer side, wherein a compression spring matched with the tyre casing outer side is arranged on the inner surface of the tyre casing outer side; a tyre casing stabilizing layer is arranged between the compression spring and the tyre casing outer side; and a tyre crown of the tyre casing outer side is closely fitted with the tyre rim through a tyre rim backing layer. The pneumatic tyre with the air supporting tyre casing is replaced by the spring tyre, so that the technical problems that the conventional tyre is easily punctured and also has the phenomena of air leakage and tyre burst are solved, and the separated safety run-flat spring tyre is not required to be inflated with air and patched and suitable for the filed of motor vehicles such as automobiles, motorcycles, bicycles, armored cars and airplanes, or non-motor vehicles.

Description

technical field [0001] The invention relates to tires, which belong to rubber light industrial products. Background technique [0002] At present, vehicle tires are divided into bias tires, steel wire tires, and solid tires. Except for solid tires, tires need to be inflated. Due to the high cost and heavy weight of solid tires, they are mainly used for special vehicles under special circumstances. Delivery tires (basically all tires with inner tubes) are basically in the elimination of technical varieties. In recent years, more and more vacuum-type steel wire tires (including semi-steel wire tires and full-steel wire tires) and vacuum-type tires (tubeless tires) are tubeless. Layer tire structure. The cover tire is made of rubber material, and the sleeve support is installed on the outer periphery of the rim (steel ring). When installing, the opening of the cover tire is facing the rim and closely matches. [0003] The material of the vacuum tire is mainly rubber and some ...

AI Technical Summary

Problems solved by technology

[0003] The material of the vacuum tire is mainly rubber and some reinforcing materials. When the tire is pierced by a sharp foreign object such as a nail, although the vacuum tire has a certain anti-puncture performance, it will cause a blowout or slow air leakage. If it happens, all pneumatic tires have a risk of puncture, which affects driving safety. At the same time, it needs to be inflated and repaired, which will increase maintenance costs and delay driving time.

In addition, there is a kind of moon landing spring tire, which is made of 800 load-bearing spring materials arranged vertically and horizontally. It is not made of rubber. The principle and process are very complicated, and the cost is too high. Especially the driving is limited, so it is not suitable for ordinary civilian use.
