Description
Technical field
The utility model relates to automobile component field, specifically comprises a kind of safety precaution wheel.
Background technology
The accident of blowing out in high vehicle speeds happens occasionally, and its consequence caused is very serious. After blowing out, position of wheel rapid decrease of blowing out, makes vehicle lose stability contorting. After at present both at home and abroad reply is blown out, the technical approach that adopts of problem out of control is: prior art 1, the reinforced special tire in sidewall, loses air pressure rear tyre sidewall support vehicle at tire and makes position of wheel decline slow down thus slow down unstability; Prior art 2, installs rigid support body additional in tire, after loss of tyre pressure, inner supporting body supports reduction position of wheel, road surface fall, thus slows down vehicle unstability; Prior art 3, patented technology CN102371843A, the wheel rim being beneficial to nonstandard wheel rim wheel carries out disappointing rear support.
All there is various defect in prior art, as follows: prior art 1, though for strengthening tire in sidewall, but rubber self character is soft elastomer, therefore supporting capacity is little, and unstable; Prior art 2, supporter weight is big, thus brings oil consumption to increase, the disadvantageous effects such as transient equilibrium variation, and supporter installs difficulty, it is necessary to professional and equipment just can carry out; Prior art 3, owing to being that inner rim itself highly increases and realizes disappointing rear support, tire construction requires its spring function, therefore it is suitable at flat ratio more than 55 tire, and very little in regulated quantity at the flat ratio used on high-grade high speed vehicle at present, there is functional defect; Sidewall is the weak location of tire, and under bad road or cross-country situation, sidewall is very easily punctured by stone and branch etc.
