Description
Technical field
The present invention relates to the automobile tyre emergency facility field of blowing out, relate in particular to the built-in emergency facility of blowing out of a kind of vacuum tire.
Background technology
When the automobile of installation vacuum tire occurs blowing out situation in the process of moving, cover tire can even come off to the groove depression of wheel rim, makes the wheel rim of wheel rim replace cover tire and support ground.On the one hand, because cover tire caves in, even comes off, cause vehicle body center of gravity to the wheel lopsidedness of blowing out, easily turn on one's side; On the other hand, because the friction coefficient between wheel rim and ground is little, cannot realize turn inside diameter, easily cause vehicle to lose direction and control.Therefore,, for the vehicle in driving process, the vehicle in particularly running at high speed, blows out and very easily causes traffic accident, even leads to the tragedy of car crash.
In the prior art, the blow out mentality of designing of emergency facility of vacuum tire can be summarized as three kinds.The first is to block wheel rim groove with the emergency facility of blowing out, thereby prevents that cover tire from coming off, and avoids wheel rim to support ground.The patent No. is that the disclosed a kind of assembly of installing around wheel rim of 01811431.8 patent of invention adopts this thinking to design, but after this assembly exists and blow out, the defect that vehicle body center of gravity inclined degree is larger.
The second thinking is that the emergency facility of blowing out is designed to comprise a hard tire that shape is similar to the inner tube of a tyre, this hard tire is connected with rim for automobile wheel by strut member, when blowing out, by this hard tire, supports vehicle body, reduce vehicle body center of gravity inclined degree, avoid vehicle to lose direction and control.The emergency facility of blowing out that adopts the second thinking to design comprises that publication number is the disclosed device of 101905628 Chinese invention patent, but this device exists the defect that must be welded with parts on rim for automobile wheel.
The third mentality of designing is that the body design of the emergency facility of blowing out is become to a cylinder, and when blowing out, by this cylinder jack-up cover tire, tyre cover lip is mentioned wheel hub, and then props up vehicle body, avoids vehicle body center of gravity generation inclination largely and vehicle to lose direction and controls.The notification number that has that embodies the third mentality of designing is the built-in anti-explosion wheel rim of tire that the invention of China of 203713430 is announced, but the built-in anti-explosion wheel rim of this tire exists the defect that is difficult to provide for vehicle power.
How to design the built-in emergency facility of blowing out of a kind of vacuum tire, make to install its vehicle when blowing out, the inclination that the unlikely generation of vehicle body center of gravity is large, and the wheel of blowing out can also be as the power wheel of vehicle, simultaneously, without rim for automobile wheel is transformed just and can be installed, be to have technical matters to be solved.
