Problems solved by technology

[0005] Safety tires of the prior art, by providing a reinforcing structure so that when the tire is in a deflated state, the structure of the safety tire has sufficient strength, excluding the sidewall and inner surface from collapsing or twisting on itself, and on the other hand, When the tire is under normal inflated operating conditions, this structure can endow favorable comfort and rolling resistance qualities, which put forward high requirements on the material and structure of the tire, thus greatly enhancing the production and use costs of the safety tire

Embodiment 3

[0045] In this example, the raw material composition of ceramics is 100 parts of α-silicon carbide; 15 parts of boron carbide; Sintered ceramics are obtained after ball milling, spray drying, dry pressing, low temperature sintering, etc.

[0046] Among them, the low-temperature sintering is sintering under the protection of argon in a high-temperature vacuum furnace. The sintering temperature is 1870°C. After the temperature in the furnace reaches the sintering temperature, the heat preservation and sintering time is 1.3h.

[0047] In this example, a ceramic sample 100 was prepared, and the pass rate of the sintered product was 99%. After testing, the average density of the sample was greater than 98%, and the fracture toughness was greater than 6.5MPa / cm 2 .

Abstract

The invention discloses a pressing explosion type dual-inner tube tire, comprising a cover, a stiffener, inner tubes, a spare tire, connecting pipes and medicament packages. The spare tire is flatly arranged on the inner sides of the inner rings of the inner tubes; the medicament packages are arranged in the cover; the medicament packages are of sealed hollow structures provided with air outlets; the air outlets of the medicament packages are communicated to an inflation port of the spare tire; internal substances in the medicament packages are at least one of kazoe or ammonium nitrate. The pressing explosion type dual-inner tube tire has a simple structure, after the inner tubes are punctured to leak, medicaments in the medicament packages are triggered to produce a great amount of high pressure gas to fill the spare tire, so as to open the spare tire to reach a normal working state to support the tire, so that the vehicle can continue to run, and the running safety of wheels can be improved.

Description

technical field [0001] The invention relates to an automobile safety tire, in particular to a detonation type double-inner tire. Background technique [0002] Tire refers to a circular elastic rubber product that rolls on the ground and is assembled on various vehicles or machinery. It is usually installed on the metal rim, which can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are usually composed of three parts: outer tire, inner tube, and pad. According to the carcass structure, it can be divided into three categories: bias tires, radial tires, and belted bias tires. [0003] The quality and safety of tires are intuitively important to the safety of a driving vehicle. In the event of a sudden tire blowout or air leak, the vehicle is prone to rollover or out of control, causing danger. [0004] Safety tires are proposed in response to this situation, which are pneumat...
