Abstract

The utility model relates to a tire, especially can automatic inflation's tire. The utility model discloses a but be equipped with an automatic inflation gasbag in former tire, the gasbag comprises an elastomer and two check valves of air outlet valve, admission valve. During the running process of a vehicle (especially a bicycle), the automatic inflation function of the vehicle tire is completed. The utility model has simple and novel structure and low cost. Brings great convenience to people (especially the majority of bicycle owners).

Description

Automatic inflation tyre

The utility model relates to a kind of tire, particularly can automatic gas filed tire.

At present, in people's daily life, the main vehicle such as automobile, motor bike, bicycle etc., these vehicle all are equipped with tire.Existing tire is generally inflatable, so just needs constantly to give inflation of tire, often need a couple of days to fill once gas, gives people's or moves and make troubles.Existing people does solid tyre, but relatively benzene is heavy, and not only waste material but also elasticity are relatively poor.

The utility model provides a kind of energy automatic gas filed tire, and it had both kept the favorable elasticity of existing tire, can automatically, constantly give inflation of tire again.Like this, can make tire be in good running state always, bring great convenience to people virtually.

The utility model is to be equipped with on original tire to the continuous inflatable air bag of tire, and air bag can be one, also can be (to contain two) more than two.

Accompanying drawing is a structural representation of the present utility model, below in conjunction with accompanying drawing, the utility model is further described.For accompanying drawing, also can regard embodiment of the present utility model as.

In the drawings, 4 is tire, and automatic air bag is housed in tire 4, and air bag has two check valves and an elastic body to constitute.Elastic body 1 is elastic sphere or the ellipsoid with certain elasticity and certain bearing force, it or a side, or two sides, or anchor ring and tire join (or bonding together), circle joins and breather check valve 2 is housed on the side of (or bonding) in it and tire 4, with the do not join side of (or bonding) of tire 4 outgassing nonreturn valve 3 is being housed, and the valve port of outgassing nonreturn valve 3 is aimed at tyre cavity, breather check valve 2 can only air inlet, and outgassing nonreturn valve 3 can only be given vent to anger.

Running condition is that tire 1 is installed in the rim, and air outlet valve 2 is stretched out by the Lao Zhuan eye of rim, is actually the Lao Zhuan that has replaced former tire, if in the tire 1 a plurality of automatic air bags are housed, then rim has a plurality of Lao Zhuan eyes to get final product.Vehicle is in traveling process, when air bag is in lower position automatically, because vehicle body and people's pressure, with elastic body 1 compression, elastic body 1 in-to-in air is flowed in the tire by air outlet valve 3, automatically air bag is in other position, aerial air is entered in the elastic body 1 by air inlet valve 2, and when locating lower position, the air in the elastic body 1 is by entering in the tire 4 at automatic air bag, so constantly give tire 4 inflations, make tire 4 remain certain pressure.In general gas is more sufficient in the tire 4, when elastic body 1 is not stressed at lower position, is not gas filed automatically, has only in the tire 4 air pressure less, and elastic body 1 is just inflated when the lower position pressurized, so just finishes the purpose to automatic tyre air inflation.When a plurality of automatic air bag is housed in the tire 4, automatic gas filed better effects if.In addition, air inlet valve 2 of the present utility model has the function in the Yuan Lao village, promptly can give inflation of tire by Floor Pump and compressor by air inlet valve 2.

The utility model is simple in structure, and is practical and wide, and cost is low again, and the difficulty that it has solved people's life or has worked and run into especially concerning vast bicycle owner, is undoubtedly a Gospel.

Claims

1, a kind of automatic air-inflation tyre is characterized in that original inside tires is equipped with to the constantly automatic inflatable air bag of tire.

2, automatic air-inflation tyre according to claim 1, it is characterized in that air bag is made of elastic body 1, air inlet valve 2, air outlet valve 3, air inlet valve 2 and air outlet valve 3 are check valves, elastic body 1 one sides or two side wheel tires 4 join (or being bonded together), air inlet valve 2 is installed in round (or being bonded together) side position that joins in elastic body and the tire, the side that air outlet valve 3 is installed in elastic body 1 and tire 4 does not join (or not having bonding).

3, automatic air-inflation tyre according to claim 2 is characterized in that automatic air bag is one, also can be for (containing two) more than two.
