Abstract
The utility model relates to an automatic air supply device for tyres, which is composed of a rubber air liner and two single-way valves. Thus, via replacing external artificial air pumping or air inflating, the automatic air supply of the tyres formed by pressurization and no pressurization owing to no air pressure or little air pressure is realized.
Description
The utility model relates to a kind of gas feeder to tire for vehicles (inner tube of a tyre), particularly can make tire finish the automatic gas feeder of self-qi of chong channel ascending adversely and maintenance stable gas pressure.
At present, the existing tyre cavity of taking turns is not when having gas or air pressure not enough, generally by exteriorly inflate, qi of chong channel ascending adversely realizes.Do not have gas in case meet tire, and during near the instrument that does not have qi of chong channel ascending adversely, inflates, will influence the normal use of tire.
The purpose of this utility model is to provide a kind of tire automatic gas feeder, as long as wheel running, it just can guarantee desired gas and air pressure in the tire by actv., and need not that inflate in the outside or qi of chong channel ascending adversely, so just can solve inflation of tire, the problem of qi of chong channel ascending adversely and air pressure deficiency.
The purpose of this utility model is achieved in that in existing tire, and a rubber gas courage is installed, and two single-pass air intake valves are set on the gas courage, and the induction opening of a single-pass air intake valve is connected in the rubber gas courage, and air gate leads to the wheel tyre cavity.The induction opening of another single-pass air intake valve is connected with outside tires, and air gate leads in the rubber gas courage.When wheel running, the position that has gas feeder on the tire is with after ground contacts, and tire does not have gas or the air pressure deficiency will be pushed down rubber gas courage, and after rubber gas courage was under pressure, the gas of the inside entered tire by the induction opening of single-pass air intake valve.When tire had the position of gas feeder and ground and disengages, rubber gas courage then began by it and outside bonded assembly single-pass air intake valve air-breathing rapidly.Thereby effectively guarantee air pressure and gas in the tire.
The utility model is because only need to connect a rubber gas courage in original vehicle tyre, and rubber gas courage is installed two single-pass air intake valves, thus simple in structure, simultaneously, can not only guarantee the gas in the tire, can also prolong the service life of tire.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof:
Fig. 1 is the automatic gas feeder section-drawing of tire that proposes according to utility model.
Below in conjunction with details and the service condition of figure detailed description according to the concrete device that the utility model proposes.
This device comprises two single-pass air intake valves (4), (14) and steel ball (6), (12) on a rubber gas courage main body (1), the main body, spring (5), (11), adjustable band eye plug (2), (10), single-pass air intake valve (4) among the figure, (14) are in the closed position.
In the embodiment shown in fig. 1, two single-pass air intake valves (4) are installed on the rubber gas courage (1), (14), the induction opening (8) of a single-pass air intake valve (4) is in rubber gas courage the inside, air gate (3) leads in the tire, the induction opening of another single-pass air valve (14) is and the outside tires bonded assembly, air gate (9) leads in the rubber gas courage, at rubber gas courage (1) when being under pressure, the gas of rubber gas courage (1) the inside rushes open steel ball (6) by the induction opening (8) on the single-pass air intake valve (4), promote spring (5), make steel ball (6) leave contact dip plane (7) and enter in the tire body by air gate (3).At rubber gas courage (1) pressure relieve or when not having pressure, the spring (5) of single-pass air intake valve (4) lining promotes steel ball (6) rapidly and gets back to contact dip plane (7), and then close single-pass air intake valve (4), meanwhile, the suction that rubber gas courage (1) produces when restoring to the original state, single-pass air intake valve (14) is started working, and rubber gas courage (1) produces suction makes steel ball (12) drive spring (11) make steel ball (12) leave contact dip plane (13).At this moment, extraneous air rapidly along induction opening (15) in air gate (9) enters rubber gas courage (1), below spring (5), (11), adjustable band eye plug (2), (10) are arranged, to adjust the dynamics of spring, promptly to guarantee rapid air inlet, also can prevent the outflow of gas.In the top of steel ball (6), (12) dip plane (7), (13) are arranged, its degree of dip is preferably in 45 °, and the dip plane is smooth, cooperates with steel ball (6), (12) no gap with assurance.
Claims (4)
1, the automatic gas feeder of a kind of tire comprises rubber gas courage and single-pass air intake valve, it is characterized in that: rubber gas courage is installed in the tire for vehicles the inside, in rubber gas courage side and bottom single-pass air intake valve (4), (14) is housed.
2, the automatic gas feeder of tire according to claim 1, it is characterized in that: the induction opening (8) of single-pass air intake valve (4) is in rubber gas courage, air gate (3) leads to the wheel tyre cavity, the induction opening (15) of single-pass air intake valve (14), be connected outside tires, air gate (9) leads in the rubber gas courage.
3, the automatic gas feeder of tire according to claim 1 is characterized in that: the band eye plug that can adjust the spring force degree is arranged in the single-pass air intake valve.
4, the automatic gas feeder of tire according to claim 1 is characterized in that the dip plane in the single-pass air intake valve is a 45, contacts with the no gap of steel ball with assurance.
