Rollable inner support device for automobile safety tire

Abstract

The invention discloses an inner supporting device capable of rolling and rotating for an automobile safety tire. The inner supporting device comprises a supporting base, rolling bodies, a retaining frame, an outer rolling ring and a self-locking device. The rolling bodies evenly distributed along the circumferences are arranged between the outer rolling ring and the supporting base. The rolling bodies are restrained through the retaining frame to form a whole structure capable of rolling around the supporting base. The rotational freedom degree of the outer rolling ring around the axis of the tire and the rotational freedom degree of the retaining frame around the axis of the tire can be limited through the self-locking device. The problems of friction heat production, rubber abrasion and the like between the rubber tire face and an inner supporting body of the inner supporting type safety tire under the low-pressure or zero-pressure traveling working condition can be effectively solved, and the inner supporting device is good in heat dissipation performance, simple in structure, capable of prolonging the running mileage of the safety tire and good in traveling safety.

Description

technical field [0001] The invention relates to a rotatable inner support device for automobile safety tires, belonging to the technical field of safety tire inner supports. Background technique [0002] Tires are the only part of the vehicle that is in direct contact with the road surface and have a significant impact on vehicle performance. However, vehicles equipped with pneumatic tires have hidden dangers such as punctures and flat tires, which seriously affect driving safety and mobility. According to statistics, 46% of traffic accidents on highways are caused by tire failures, and tire blowout alone accounts for 70% of the total tire accidents. The death rate caused by a tire blowout at a vehicle speed of more than 160 kilometers per hour is close to 100%. In order to solve problems such as tire blowout, puncture prevention, spare tire-free, and bulletproof, safety tire technology has become an important direction of current tire technology development and is the core...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rotatable inner support device for automobile safety tires, which can effectively alleviate the violent tension between the rubber tread and the inner support when the inner support type safety tire rolls under low pressure or zero pressure. friction heat dissipation, rubber wear and other problems, and improve the mileage of safe tires
