Description
Technical field
The invention belongs to automotive wheel technical field, and in particular to can effectively prevent to lose control of one's vehicle and take turns when blowing out
It can ensure that vehicle continues the safety wheel of normally travel during the serious deficency of 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 reason such as aging gas leakage causes wheel deficency to exercise, many drivers lack experience or equipment cannot
Tire is changed, is wasted time.For this reason, people are researching and developing run-flat tire always, even if occurring blowing out also effectively can prevent vehicle from losing
Control, 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, self-closing, the section between two tire shoulder of tyre cavity, are provided with
Special antipricking layer, built-in flowable sealant；After pierced or extraction is pierced into thing, sealant is acted in tire pressure
Flow to automatically at perforation down, block 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, a circle support ring on set on wheel hub, its greatest problem is must to use very
Special wheel hub, is installed when dispatching from the factory using special process, once damaged tyres, can not repair and replacement, can only integral replacing, cost
It is high.
The content of the invention
The purpose of the present invention is in view of the deficiency of the prior art, there is provided a kind of low cost, be easily installed maintenance,
Do not influence riding comfort under normal circumstances, can safely traveling over long distances lacks under tire deficency and zero barometric information
Gas warranty safety tread.
The purpose of the present invention is achieved through the following technical solutions：
A kind of run-flat safety tread, including special wheel hub, be equipped with special wheel hub 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 groove, wheel rim, spoke, ring flange, valve port；
The fixing seal ring is fitted to special wheel hub side, is coordinated by annular bead and groove and is embedded in and using fastening
Screw is connected with special wheel hub, and seal washer is lined with 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 outwards gradually inside contracted, 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 groove offers venthole.
The present invention is provided with a circle annular bead in the inner face of fixing seal ring, in the wheel rim inner face pair of special wheel hub
Should be provided with a ring annular groove, in annular bead insertion annular groove, using horizontal trip bolt by fixing seal ring with
Special wheel hub is fastenedly connected.The present invention can also set a ring annular groove in the inner face of fixing seal ring, in special wheel hub
Wheel rim inner face is correspondingly arranged a circle annular bead, and annular bead is embedded in annular groove, will be solid using horizontal trip bolt
Determine sealing ring to be fastenedly connected with special wheel hub.
Tire using the present invention, can pass through branch by the valve port aerating on special wheel hub wheel rim, gas through aerating groove
Venthole on pushing out ring enters tire, is tyre inflating.When tyre explosion or deficency, tire slightly it is flat get off after touch branch
Pushing out ring, support ring withstand tire from inside, and vehicle only occurs small lateral deviation, can continue to normally travel, it is possible to prevente effectively from
During common wheel deficency there is a situation where serious lateral deviation occur it is out of control, avoid accident.The present invention prime advantage be,
Support ring is manufactured using foam rubber, is had quite flexible and elastic, when tire deficency, be not only avoid presently the most normal
Side wall support formula tire influences very much vehicle riding comfort, acutely shakes damage vehicle structure problem firmly, and wheel hub
Cost increase is little, can still use conventional tire, more preferable than existing three kinds of tire anti-explosion technique effects, and dismounting is more square
Just, and since internal support ring can effectively block tire, will not fall off after tire deflation, it is safer.
