Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figures 1 to 8, the foamed damping inner tube of a tyre of a kind of internal airbag, including inner tube of a tyre body 1, inner tube of a tyre body 1 are one
Kind foaming structure, the one week air bag 2 for being provided with multiple equidistantly distributeds in the inside of inner tube of a tyre body 1, air bag 2 carry wall thickness, air bag 2
Interior space is confined space, be filled with carbon dioxide in air bag 2, and the pressure in air bag 2 is not less than outside nature
Pressure.
In the present embodiment, the cross sectional shape of the air bag 2 is hollow circle, ellipse, dumb-bell shape or fusiformis.Air bag 2
For circular arc.Pressure in air bag 2 is 1.0-1.6 times of outside nature pressure.The outside of air bag 2 is provided with fixture 3, air bag 2
It is positioned at by fixture 3 in the inner tube of a tyre body 1.
In the present embodiment, the quantity of the fixture 3 and air bag 2 matches, and fixture 3 is located in each air bag 2
Between position.Fixture 3 includes locating ring 4, and locating ring 4 is enclosed in the outside of air bag 2, and the outside of locating ring 4 is connected with branch
Strut 5, support bar 5 are stretched in the inner tube of a tyre body 1 outside air bag 2.Locating ring 4 carries opening.The connection of the outside of locating ring 4 is more
Support bar 5 described in root, support bar 5 radially distribute.
The utility model is a kind of foamed damping inner tube of a tyre of internal airbag, including inner tube of a tyre body can filling gas with several
Air bag, is provided with multiple gas bag units in inner tube of a tyre body, air bag inner tube of a tyre body interior equidistantly it is circumferential uniformly, air bag has in itself
There is a good air-tightness, the space in air bag is confined space, is filled with carbon dioxide in air bag, and the pressure in air bag is big
Fixture is provided with outside the pressure of outside nature, air bag, air bag is positioned in inner tube of a tyre body by fixture.
In the present embodiment, the pressure in air bag is 1.0-1.6 times of outside nature pressure.Fixture includes positioning
Ring, locating ring are enclosed in outside the air bag, are connected with support bar outside locating ring, support bar stretches to interior outside air bag
In tire body.
In addition, locating ring can carry opening, the air bag outside quantity of fixture and the quantity of air bag match, and positioned at every
The middle part of individual air bag.The more support bars of connection, support bar radially distribute outside locating ring.Air bag can be located at interior
The center of tire body, it may be alternatively located at the partially interior place of inner tube of a tyre body.The quantity of air bag can be circumferential equidistantly uniform along inner tube of a tyre body
It is multiple.
When producing the foaming inner tube of a tyre described in the utility model, its internal increase airbag structure, the cross sectional shape of its air bag can
For the deformation or combination of circle, ellipse, dumb-bell shape, fusiformis or these shapes, these shapes can be very good to adapt to the outer of cover tire
Shape, ensure the thickness at each position of foaming inner tube of a tyre body；Meanwhile circle etc. can equally bear all directions external pressure, bending resistance
Compression strength is big, and does not have directionality.Filling gas in air bag, make inside air bag that there is certain pressure, sent out for improving

In the utility model, its internal airbag structure can taken turns along the circumferential uniformly arrangement 2,3 or multiple of tire
During tire use, if single air bag, just in case after being punctured gas leakage, other air bags still provide certain tire pressure, make tire after
Continuous normal use.
The inner tube of a tyre of this structure can effectively improve the comfort level of tire in ride, reduce the rolling resistance of tire.
The production method of the foamed damping inner tube of a tyre is as follows：
1st, the production of internal airbag：
The tubing cut-to-length that size as requested is customized first, is then glued each balloon ends opening by viscose glue
Close sealing.To ensure that inside air bag has appropriate pressure（It is preferred that determine that pressure is 1.0-1.6Mpa）, while joint connects to
Inside air bag stowing pressure.Through preferred, filling carbon dioxide is the production method for being easier operation, during the adhesive seal of end
Load weighted dry ice is put into air bag in advance, then carries out joint connection, waits the pressure inside dry ice gasification rear gasbag to stablize
Between 1.0-1.6MPa.
2nd, the arrangement of air bag fixture：
To ensure fixation of the air bag in foaming mould, through preferred, can easier be entered using special airbag fixture
Row production according to the cross sectional shape of air bag, it is necessary to customize fixture, the quantity of fixture and the quantity Matching of air bag are general each
Air bag needs a fixture, according to the length adjustment of air bag, if balloon length increases, needs of corresponding increase fixture
Number, air bag fixture are typically disposed in the middle part of air bag, and Fig. 1, which is shown in inner tube of a tyre body, is distributed with 4 air bags, each air bag
One fixture is installed.
3rd, the production of the built-in arc air bag foamed damping inner tube of a tyre：
First the air bag for installing fixture is placed in foaming inner tube mold, then axis of rotation of the mould along die cavity is turned
It is dynamic, polyurethane compound is injected into mould with foaming machine, polyurethane compound is full of mould by centrifugal force, the temperature of mould is excellent
Selected control system molds between 40-50 DEG C after three minutes.
In the utility model, the making material of internal airbag includes the various high scores such as rubber, plastics, thermoplastic elastomer (TPE)
Sub- material.The gas of filling is included under the various normal temperature such as air, nitrogen, carbon dioxide with thing existing for gaseous state in air bag
Matter.The section configuration of air bag includes a variety of shapes such as circle, ellipse, dumb-bell shape, fusiformis.The position of air bag is positioned at foaming
Inner tube of a tyre center, the wall thickness requirement of air bag are more than 1.0mm, as wall thickness is too small, effective support can not be formed to tire.Air bag
The foamed glue thickness requirement in outside is more than 8mm, otherwise can not effectively buffer and protect air bag not poked by nail.
