Problems solved by technology

Coatings are generally only suitable for blocking small air leaks, but cannot effectively block larger cracks
The coating increases the thickness of the tire crown, increasing driving heat will have a negative impact on use

Embodiment Construction

[0016] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 The shown double-chamber safety tire with built-in airbags is composed of a tire 1 and a rim 4, the tire valve 7 is arranged on the rim 4, and the first chamber 2 formed between the tire 1 and the rim 4; the first chamber A safety airbag 5 is arranged in the chamber 2, and the material of the safety airbag 5 is a vulcanized rubber elastic body, and the thickness of the bag wall is 1.5mm. The inner side of the airbag 5 leans against the rim 4 , and the two shoulders of the airbag 5 are respectively provided with sponge protective layers 6 . A second chamber 3 is formed in the airbag 5, and the second chamber 3 is completely wrapped in the first chamber 2 by the airbag 5, and the volume of the second chamber 3 accounts for the first chamber 2 and the second chamber 3. 60% of the total volume. The rim 4 is...

Abstract

The invention relates to a double-cavity safety tire. The double-cavity safety tire with an internal airbag comprises an outer tire and a rim; the rim is provided with an outer tire air valve, and a first cavity is formed between the outer tire and the rim; a safety airbag is arranged inside the first cavity, the inner side of the safety airbag leans against the rim, a second cavity is formed in the safety airbag, and the second cavity is totally enwrapped inside the first cavity by the safety airbag; and the rim is provided with a valve port, the air valve of the safety airbag penetrates through the valve port, and an outer ring of the air valve of the safety airbag is sealed with the valve port. In the moment when a tire breaks accidentally and air leaks immediately, the safety airbag of the double-cavity safety tire can support the tire to avoid severe distortion, prevent accidents due to loss of control of a vehicle and protect the safety of persons and the vehicle. When the safety airbag expands to tightly cling to the inner surface of tire, the air pressure in the safety airbag can totally ensure that the vehicle can travel to a relative nearby maintenance station to replace or repair the tire.

Description

technical field [0001] The invention relates to a double-cavity safety tire. Background technique [0002] Since the invention of automobile technology, the highest state of pneumatic tire technology is how to eliminate or minimize the impact of tire leakage. Road hazard concerns have long been an issue for pneumatic tires. When tires are used on the road, they often encounter air leakage due to puncture or even impact rupture. The process of tire leakage is sometimes very rapid, often causing serious vehicle out-of-control accidents. In order to deal with the sudden damage of tires on the road, the vehicle has to be loaded with a spare tire, which not only takes up valuable space, but also increases the quality of the vehicle. In the past ten years, many new technologies have been developed for run flat tires, some of which have been commercialized, mainly in three types: [0003] 1. Self-supporting flat tire: This type of tire has elastic supporting parts on the inner s...
