Description
Technical field
The utility model belongs to automotive wheel technical field, and in particular to can be effectively prevent to lose control of one's vehicle when blowing out
It can guarantee that vehicle continues the safety wheel of normally travel when deficency serious with tire.
Background technology
On highway, one of most commonly seen major accident is exactly to blow out initiation to lose control of one's vehicle；In many cases, by
Pierced through in wheel, the reasons such as aging gas leakage cause wheel deficency that cannot exercise, many drivers lack experience or equipment cannot
Tire is changed, is wasted time.For this purpose, people are researching and developing always run-flat tire, even if occurring blowing out can also effectively prevent vehicle to lose
It controls, ensure that vehicle continues the tire exercised.Existing run-flat tire mainly has following three kinds of classifications：First, sidewall adds
Thick brace type, when tire deflation, sidewall can support vehicle traveling tens or even up to a hundred kilometers of arrival tyre repairs.
The greatest problem of this technology is that tire lacks flexibility, and the comfort not only taken under normal circumstances substantially reduces, Er Qiehui
Because the sharp pounding of normalization can damage vehicle structure；Second is that self-closing, the section between two tire shoulder of tyre cavity, are provided with
Special antipricking layer, built-in flowable sealant；After being pierced or extracting piercing object, sealant is acted in tire pressure
It flows at perforation automatically down, blocks hole, keep tire air tight.Its greatest problem be can only anti-tingle pierce through, and cost is very
Height, timeliness are limited；Third, internal support ring type, covers upper circle support ring on wheel hub, greatest problem is must to use very
Special wheel hub, when manufacture, are installed using special process, once damaged tyres, can not repair and replacement, can only integral replacing, cost
It is high.
Invention content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of low cost, be easily installed
Repair, do not influence riding comfort under normal circumstances, can under tire deficency and zero barometric information safely row over long distances
The run-flat safety tread sailed.
The purpose of this utility model is achieved through the following technical solutions：
A kind of run-flat safety tread, including special wheel hub, with special wheel hub be equipped with fixing seal ring, be sleeved on specially
The tire on groove formed with wheel hub and fixed seal ring, the support ring being sleeved on special wheel hub；
The special wheel hub includes wheel rim, fixing seal mouth, aerating slot, wheel rim, spoke, ring flange, valve port；
The fixing seal ring is fitted to special wheel hub side, is embedded in and using fastening by annular bead and groove cooperation
Screw is connect with special wheel hub, and seal washer is lined in groove；
The tire sleeve positions on special wheel hub and by sealing ring clamping；
The section of the support ring is the arc chord angle isosceles trapezoid gradually inside contracted outward, and support ring is sleeved on wheel rim and is located at
In tire, tire toe is enclosed in the left and right two that the branch brace shoulder of left and right two of support ring suppresses tire respectively, wherein in side branch brace shoulder with
The corresponding position of aerating slot offers venthole.
The utility model is provided with a circle annular bead in the inner face of fixing seal ring, in the wheel rim inner end of special wheel hub
Face is correspondingly arranged on a ring annular groove, and annular bead is embedded in annular groove, using lateral trip bolt by fixing seal
Ring is fastenedly connected with special wheel hub.Also a ring annular groove can be arranged in the inner face of fixing seal ring in the utility model, special
It is correspondingly arranged a circle annular bead with the wheel rim inner face of wheel hub, annular bead is embedded in annular groove, using lateral fastening
Fixing seal ring is fastenedly connected by screw with special wheel hub.
, can be by the valve port aerating on special wheel hub wheel rim using the tire of the utility model, gas is logical through aerating slot
The venthole crossed in support ring enters tire, is tyre inflating.When tyre explosion or deficency, tire slightly it is flat get off after contact
To support ring, support ring withstands tire from inside, and vehicle only occurs small lateral deviation, can continue to normally travel, can be effective
It avoids avoiding accident there is a situation where serious lateral deviation occurs out of control when common wheel deficency.The maximum of the utility model is excellent
More property is, support ring is manufactured using foam rubber, has comparable flexible and elasticity, when tire deficency, not only avoids
Presently the most common side wall support formula tire influences very much vehicle riding comfort, acutely shake damage vehicle structure problem firmly,
And the cost of wheel hub increases less, can still use conventional tire, and it is more preferable than existing three kinds of tire anti-explosion technique effects,
It dismounts more convenient, and since internal support ring can effectively block tire, will not fall off after tire deflation, it is safer.
