Tire burst preventive safety mechanism for automobile

Abstract

The invention discloses a tire burst preventive safety mechanism for an automobile. A support ring of the tire burst preventive safety mechanism is mounted on the annular outer surface of a wheel rim,is at least provided with a notch and is broken at the notch, a connecting component is arranged at the notch of the support ring and is used for being connected with the support ring, a plurality ofpendulum hammer components are arranged on the outer periphery of the support ring, an antiskid ring or a rubber ring is arranged on the inner wall of the support ring, second openings are formed inthe antiskid ring or the rubber ring, and 'V'-shaped tongue pieces can be stored in the second openings via first openings. The tire burst preventive safety mechanism has the advantages that a supportring body is connected to the surface of the wheel rim to form the support ring, the support ring is provided with the multiple pendulum hammer components, the pendulum hammer components can swing out under the effect of centrifugal force when a tire is in dynamic balance or the travel speeds of the automobile are higher than 30 km/H, the tire can be effectively safely supported after being burst, the inner side edge of the tire can be supported by pendulum hammers at the moment, the tire can be positioned on the outer periphery of the wheel rim under the control when burst and is still in contact with pavements, accordingly, the directions can be guaranteed against getting out of control, and safety effects can be realized.

Description

technical field [0001] The invention relates to automobile safety technology, in particular to a safety mechanism for automobile run-flat tires. Background technique [0002] 46% of domestic highway traffic accidents every year are caused by tire accidents, of which tire blowouts account for 70%. [0003] Among the mature technologies, the groove filling scheme represented by Tyrone in the United Kingdom has the following points to be improved: [0004] The product has high quality and high fuel consumption; it is difficult to install and requires the use of special tools or tooling, which makes it difficult to meet the mass assembly requirements of OEMs (2 pieces / minute); the cost is high, and the user's use cost is too high. [0005] The application number is: CN1437535A, a kind of cushion belt for rims, in the disclosed technical solution, a component (10) installed around the rim, the component (10) is suitable for use as a flat tire driving component or a sidewall lock...

AI Technical Summary

Problems solved by technology

[0009] This patent document also cannot effectively control the blown tires around the outer periphery of the rim during use, and there will be a hard contact between the rim and the road surface, which will also cause deviation.
