car safety tire

Abstract

The invention discloses an automobile safe tire which comprises an outer tire body (2) and a rim (3) connected with the outer tire body (2). A protective film (1) is arranged in the outer tire body in the circumferential direction. The edges of the two sides of the protective film (1) are fixedly bonded with the outer tire body (2) or the rim (3) in an airtight mode, so that a tire air cavity is defined by the protective film (1), the outer tire body (2) and the rim (3). The protective film (1) is an annular flexible film manufactured from an airtight material, or is a strip-shaped film with the two ends capable of being connected to form an annular shape or is a unit membrane capable of being spliced into an annular shape. The automobile safe tire makes up shortcomings of major methods such as active damage prevention of current rigid automobile tires, can improve automobile traveling safety and has a positive effect.

Description

technical field [0001] An automobile safety tire disclosed by the invention belongs to the field of automobile manufacturing. Background technique [0002] With the continuous growth of car ownership, traffic accidents often occur and affect people's travel. The safety of automobile tires is one of the important assessment indicators of automobile safety. Being punctured by sharp objects is one of the important reasons for tire deflation and bursting. At present, the mainstream preventive measures include anti-puncture and automatic treatment after puncture. Specifically, there are methods such as improving the puncture resistance of the outer tire, pre-setting self-replenishing agents, and elastic retraction and self-sealing of the airtight layer. Improving the anti-puncture strength of the tire is a rigid resistance method, which often needs to be implanted with high-strength materials such as polymer fabrics and steel plates, which will increase the thickness, weight, ma...

AI Technical Summary

Problems solved by technology

Improving the anti-puncture strength of the tire is a rigid resistance method, which often needs to be implanted with high-strength materials such as polymer fabrics and steel plates, which will increase the thickness, weight, manufacturing difficulty and cost of the tire, and the anti-puncture effect is limited to the anti-puncture material. The amount of implantation; the preset self-replenishing agent has a validity period, and it cannot repeat self-replenishing in the same place, and it will liquefy and flow at high temperature, which will affect the balance of the tire; now the inner tube inner tube is fixed on the inner surface of the outer tire, and it is easy to be punctured Piercing, it can rebound to block smaller breaches after piercing, but it only slows down the speed of deflation, and it is not effective for larger breaches
