Abstract
The utility model relates to an automobile mother and son tire and belongs to the technical field of tires. In order to solve the problem in the prior art that the air pressure in a tire quickly reduces to easily cause traffic accidents in the case of tire burst of a tire without inner tube. The utility model provides a mother and son tire comprising a mother tire, a wheel hub provided with a mother tire air tap and a son tire located between the mother tire and the wheel hub; and gas is filled in the son tire and the mother tire, when the mother tire leaks gas or bursts, the gas in the son tire expands to support the normal operation of the automobile.
Description
Technical field
The utility model relates to a kind of automobile primary and secondary tire, belongs to tyre technology.
Background technology
Present conventional tyre generally is made up of tyre surface, tire shoulder, sidewall, tyre bead, carcass, cushion layer or bracing ply, interior lining; Tubeless tires is made up of carcass plies, bracing ply, crown, tire shoulder and tyre bead, and with bracing ply banding carcass; Run-flat tire; With maximum different of general tire is exactly to be that it has the very tyre sidewall of flexible and supportive, and such design can help tire blowing out or disappointing suddenly situation, and assurance tire and wheel hub can also combine and give vehicle certain support; Thereby guarantee vehicle safety; But its traveling comfort is bad, repairs pretty troublesomely, and cost is high.
Summary of the invention
When solving that tubeless tires is blown out in the prior art, the rapid reduction of tire internal gas pressure causes the problem of traffic accident easily, and it is a kind of when tubeless tires is blown out that the utility model provides, and can prevent the primary and secondary tire that the tire internal gas pressure reduces rapidly.
The technical scheme of the utility model:
The primary and secondary tire that the utility model provides comprises female tire, is provided with the wheel hub of female cranked tire valve and the sub-tire between female tire and wheel hub; Described female tire is a tubeless tires; Described sub-tire is made up of the carcass that is shaped as the ring seal tube that the has sub-cranked tire valve cord fabric outer with being wrapped in carcass; Described wheel hub is provided with the valve mouth that adapts with sub-cranked tire valve.
The primary and secondary tire that the utility model provides is preferably between sub-tire and female tire and is provided with the toroidal confinement band; And the bilateral symmetry of restraint strap is provided with hook; Simultaneously wheel hub inwall both sides be provided with restraint strap on the corresponding rotary hook ring of hook.
The primary and secondary tire that the utility model provides, the hook of its restraint strap preferably have the hook cover.
The beneficial effect of the primary and secondary tire that the utility model provides:
Comprise sub-tire and female tire, all be filled with gas in sub-tire and the female tire, when female tire flat or explosion, the gas in the sub-tire expands, and is enough to support the normal operation of automobile.Thereby actv. has been when having prevented tire blow-out, the generation of the traffic accident of car crash.Simultaneously, during female tire flat because the existence of sub-tire has significantly reduced the infringement to wheel hub and female tire.
Description of drawings
Fig. 1 is the transverse sectional view of tire;
Among the figure, 1. female tire, 2. sub-tire, 3. wheel hub, 4. restraint strap, 5. sub-cranked tire valve, 6. female cranked tire valve.
The specific embodiment
The primary and secondary tire that the utility model provides comprises female tire 1 and sub-tire 2;
Female tire 1 is exactly a common tubeless tire, is installed on the wheel hub 3, and wheel hub 3 has an independently female cranked tire valve 6; Sub-tire 2 is made up of carcass and cord fabric; Carcass be shaped as the ring seal tube identical with the inner tube of a tyre of conventional tyre, and an independently sub-cranked tire valve 5 is arranged on the carcass; Cord fabric is wrapped on the carcass, forms cryptomere.
Between female tire 1 and the sub-tire 2 cyclic spring rubber restraint strap 4 is arranged; The bilateral symmetry of elastic caoutchouc restraint strap 4 is provided with hook; Be with the hook cover on the hook; The inwall both sides of wheel hub 3 are provided with and link up with corresponding rotary hook ring, and the hook on the elastic caoutchouc restraint strap 4 hangs on the hook ring of wheel hub 3.
Installation steps are following:
The first step is installed female cranked tire valve 6;
In second step, the carcass of bundle tire 2 is installed on the wheel hub 3;
The 3rd step was rolled in cord fabric outside the carcass of sub-tire 2, and the size overlapping sub-fraction of cord fabric by sign, was bonded together with super glue at lap, became cryptomere; After bonding the getting well, the external diameter of cord fabric capsule should equal the internal diameter of female tire 1;
The 4th step installed sub-cranked tire valve 5 and elastic caoutchouc restraint strap 4 is installed outside the cord fabric capsule, hung over the hook of elastic caoutchouc restraint strap 4 both sides on the hook ring of wheel hub 3, and installed the hook overcoat;
In the 5th step, be installed in female tire 1 on the wheel hub 3;
In the 6th step, through sub-cranked tire valve 5,2 inflations of antithetical phrase tire simultaneously through female cranked tire valve 6, are emitted the gas in female tire 1; During lower limit air pressure when the air pressure in female tire 1 is cruising, this moment, sub-tire 2 took the whole space in female tire 1, can support female tire 1, just as the tire of a band inner tube of a tyre;
The 7th step is through female tires 1 inflation of 6 pairs of female cranked tire valves, when the air pressure of female tire 1 during greater than the air pressure of sub-tire 2; Sub-tire 2 just begins to diminish; And separate with female tire 1, until the air pressure of female tire 1 during to cruising the air pressure upper limit or slightly less than the upper limit, the air pressure in this moment sub-tire 2 are being ignored under the situation of other factors; Equate with the air pressure of female tire 1; Elastic caoutchouc restraint strap 4 will be the cord fabric bag pressure on the carcass of sub-tire 2 at this moment, and owing to the pressure of elastic caoutchouc restraint strap 4, sub-tire 2 just is pressed on the wheel hub 3 simultaneously.
When gas leakage taking place or blow out, the air pressure of female tire 1 reduces, and the pressure that this moment, sub-tire 2 received begins to diminish, volume becomes big; When female tire 1 gas has leaked, sub-tire 2, no longer continues to become big owing to receive the constraint of cord fabric capsule when its external diameter equals the internal diameter of female tire 1; Owing to the constraint of cord fabric capsule, sub-tire 2 just can not expand at the degree of making a slip of the tongue of blowing out simultaneously; This moment sub-tire 2 air pressure, the air pressure when inflating for the first step is female tire 1 cruising air pressure of lower limit constantly; The sub-tire 2 of this moment is just supporting female tire 1, and whole tire is just as tube tyre, and automobile can cruising stretch journey.
