Abstract

A double-tire tube emergency system for a wheel comprises a tire tube inside, a tire tube outside, an outer tire, a spider, a vehicle shaft, a gas distributing valve, a high-pressure gas bag, a one-way valve, a middle pipeline, a left pipeline and a right pipeline; an upper inner chamber and a lower inner chamber are respectively arranged at two ends of the gas distributing valve including a cylinder body and a piston, through holes are respectively formed on the wall of the cylinder body corresponding to two inner chambers, and the through holes are formed at the middle part on the wall of the cylinder body; the through holes and the one-way valve for inputting gas are formed on the high-pressure gas bag; the tire tube inside and the tire tube outside are positioned on the inner sides of the outer tire respectively; and the gas distributing valve is communicated with the tire tube inside through the middle pipeline, communicated with the tire tube outside through the left pipeline and communicated with the high-pressure gas bag through the right pipeline respectively. If the tire tube inside explodes, the air pressure of the upper inner chamber communicated with the tire tube inside is reduced. The piston moves towards the tire tube inside under the action of pressure difference and seals the through holes of the upper inner chamber, and the pressure in the high-pressure gas bag enters the tire tube outside and further bulges the tire tube outside so as to achieve the original gasification state of the outer tire, thereby avoiding the accident caused by explosion of the tire tube.

Description

The two inner tube of a tyre calibration packages of wheel

Affiliated technical field

The utility model relates to the two inner tube of a tyre calibration packages of a kind of wheel.

Background technology

As everyone knows, the wheel of many vehicles all is provided with the gas filed inner tube of a tyre and the rubber cover with defencive function for damping.Because interior tire has higher pressure, therefore the example that is caused the accident by the blow-out of the inner tube of a tyre is also of common occurrence.Though someone proposed improvement idea to this, its effect always can not be satisfactory.For this reason, the present invention releases a kind of two inner tube of a tyre calibration packages that are applicable to the inflation wheel.Two inner tube of a tyre inflation wheels of using this system are when unexpected explosion appears in an inner tube of a tyre, and what another inner tube of a tyre can be in good time under the effect of calibration package is inflated again, thereby ensures that its cover of wheel can normally move, avoid causing the accident.Find no the invention of identical structure by retrieval.

Summary of the invention

At present, used widely though have the wheel of the inner tube of a tyre, also there is such problem in it: as if its inner tube of a tyre blow-out, vehicle will produce or sideslip wheel so, usually accident will occur for this reason when moving fast.The two inner tube of a tyre calibration packages of the wheel that the utility model is released, its purpose is exactly the problem that will solve this respect.The basic skills of this calibration package is: place two inflatable inner tubes in the rubber cover, and they join a high pressure gas bag altogether, in case explosion appears in an inner tube of a tyre, the high pressure gas bag can further be inflated to another inner tube of a tyre moment, avoids vehicle to occur tilting or sideslip according to this.

The two inner tube of a tyre calibration packages of a kind of wheel, it is to be made of the inboard inner tube of a tyre, the outside inner tube of a tyre, cover, spoke, axletree, gas distributing valve, high pressure gas bag, check valve, middle pipeline, left pipeline, right pipeline; Gas distributing valve is the cylinder body and the piston that seal shape by two ends and constitutes, and piston is divided into its inner chamber of cylinder body goes up inner chamber and lower inner cavity, and inner chamber and lower inner cavity are respectively equipped with through hole on correspondence on the wall of cylinder body, are provided with through hole at the middle part of its wall of cylinder body; On its wall of high pressure gas bag, be provided with through hole and be used for the check valve that gas is imported; The inboard inner tube of a tyre and the outside inner tube of a tyre place the both sides in its cover of wheel respectively; Middle pipeline UNICOM is in the through hole of gas distributing valve and the induction opening of the inboard inner tube of a tyre; Left side pipeline UNICOM is in the through hole of gas distributing valve and the induction opening of the outside inner tube of a tyre, and right pipeline UNICOM is in the through hole of gas distributing valve and the through hole of high pressure gas bag; When the air pressure inside of the inboard inner tube of a tyre and the outside inner tube of a tyre was balanced, the through hole that the piston in the gas distributing valve can be provided with the middle part sealed.

Beneficial effect of the present invention: can reduce or avoid the contingency that causes owing to the inner tube explosion.

The specific embodiment

The utility model as shown in Figure 1, it is made of the inboard inner tube of a tyre (1), the outside inner tube of a tyre (2), cover (3), spoke (4), axletree (5), gas distributing valve (6), high pressure gas bag (12), check valve (14), middle pipeline (15), left pipeline (16), right pipeline (17);

Under the normal use state, the be placed in interior both sides of its cover of wheel (3) of the inboard inner tube of a tyre (1) and the outside inner tube of a tyre (2); When the air pressure inside of the inboard inner tube of a tyre (1) and the outside inner tube of a tyre (2) was balanced, the piston (11) in the gas distributing valve (6) was divided into inner chamber (71) and lower inner cavity (72) with its inner chamber, and through hole (10) is sealed; High pressure gas bag (12) Qi Bishang is provided with the check valve (14) that carries out the gas input; The connection situation of each pipeline is:

Pipeline (15) UNICOM is in the induction opening of the through hole (8) and the inboard inner tube of a tyre (1) in gas distributing valve (6) warp; Gas distributing valve (6) is the induction opening in the through hole (9) and the outside inner tube of a tyre (2) through left pipeline (16) UNICOM; Gas distributing valve (6) is the through hole (13) in through hole (10) and high pressure gas bag (12) through right pipeline (17) UNICOM.

When if explosion takes place the inboard inner tube of a tyre (1), the air pressure in the inboard inner tube of a tyre (1) then will descend moment.Meanwhile, its air pressure of last inner chamber (71) with the gas distributing valve (6) of the inboard inner tube of a tyre (1) UNICOM also descends thereupon.Like this, under the effect of draught head between last inner chamber (71) and the lower inner cavity (72), one, piston (11) is pulled to inner chamber (71) and locates; Its two, sealed by piston (11) with the through hole (8) of the inboard inner tube of a tyre (1) UNICOM.Simultaneously, pressure in the high pressure gas bag (12) is the induction opening of via through holes (13), right pipeline (17), through hole (10), through hole (9), left pipeline (16) and the outside inner tube of a tyre (2) and the inner tube of a tyre (2) outside entering successively, with further inflation of the outside inner tube of a tyre (2), the outside inner tube of a tyre (2) that instantaneous expansion rises is full of the inner chamber of cover (3).For this reason, this system can reduce or avoid the accident that caused by inner tube of a tyre blow-out.
