Abstract
The present invention discloses a non-inflatable inner tube. In the non-inflatable inner tube, an outer annular hollow sleeve is sheathed with an inner annular hollow sleeve, the inner edges of the two annular hollow sleeves are connected into integration, and the inner tube is made from polyamide resin. The non-inflatable inner tube has the advantages that the non-inflatable inner tube resists press and collision of any hard objects, runs smoothly, stops driving accidents and parking repair caused by tyre bursts or economic loss caused by changing tyres, relieves emergency tyres and emergency tyre elevating mechanisms, reduces production cost, and lightens vehicle weight. The non-inflatable inner tube with the structure is suitable for motor vehicles, such as automobiles, etc., and is suitable for non-motor vehicles, such as bicycles, etc.
Description
Technical field: the present invention relates to the inner tube of a tyre on a kind of wheel, be specifically related to Uninflated inner tube.
Background technology: at present, the general-duty automobile inner tube all adopts elastomeric material to make, and by tire tube valve pressurized air is poured into wherein.Inflatable inner tube very easily is subjected to the influence of a variety of causes and causes damaging or explosion, and is too high as air pressure, can quicken treadwear or blows out; Air pressure is low excessively, can crack, and influences service life, increases oil consumption, influences the speed of a motor vehicle.Peg, sheet and stone etc. also often puncture the inner tube of a tyre and explosion influences traffic safety; Repairing and change the inner tube of a tyre has then increased frame and has sailed personnel's labour intensity.
Chinese patent CN2098400 discloses a kind of be not afraid of stamp, Uninflated inner tube, it is made by rubber, the duct that two symmetries are arranged in the middle of the inner tube of a tyre, wall thickness is between 0.4-0.8cm, the inner tube of a tyre has two end points for disconnecting shape, must be installed in the purpose made drop-center rim, because this inner tube of a tyre is not an integral body, so be only applicable to bicycle and dilly.CN2335807 discloses another kind of structure Uninflated inner tube, it forms a constitutional formula circular structure body by outer ring, inner ring, horizontal circle pressure column, pressure is transferred to inner ring by the outer ring by horizontal circle pressure column, this inner tube of a tyre is owing to exist horizontal circle pressure column, therefore, sensuously there is not inflatable inner tube steady like that in operation.
Summary of the invention: technical matters to be solved by this invention provides a kind of Uninflated inner tube, and it is an integral structure, be not afraid of stamp, do not blow out, and sensation is steady when vehicle operating.
For solving the problems of the technologies described above, the technical scheme that Uninflated inner tube of the present invention adopts is such: annular hollow sleeve in it also is with in the outer ring hollow sleeve, the inner edge of two annular hollow sleeves is connected to integral body.
The inner edge profile of above-mentioned two annular hollow sleeves and the outer rim of wheel rim coupling.
The both sides wall thickness of above-mentioned two annular hollow sleeves is greater than the wall thickness that contacts with the road surface.
The above-mentioned inner tube of a tyre is by the amilan manufacturing.
Because Uninflated inner tube adopts two siamesed annular hollow sleeve structures, the annular cover of outside is stressed, the annular of the inside has been overlapped safety effect, and material changes duroplasts (amilan) into by soft rubber, therefore, it does not mind any hard thing roof pressure and collision, operate steadily, the train operation accident and the parking of having stopped to cause, repair or change the economic loss that tire causes, exempted spare tire and spare tyre lifting mechanism because of blowing out, reduce productive costs, alleviated tare.The Uninflated inner tube of this structure not only is suitable for self-propelled vehiclees such as automobile, also is applicable to unpowered vehicles such as bicycle.
Description of drawings: Fig. 1 is the scheme drawing of Uninflated inner tube of the present invention;
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
The specific embodiment: as seen by Fig. 1, Fig. 2, Uninflated inner tube of the present invention is made up of outer ring hollow sleeve 1 and interior annular hollow sleeve 2, interior annular hollow sleeve 2 is enclosed within outer ring hollow sleeve 1 the inside, play safety effect, the inner edge 3 of two annular covers is connected to integral body, inner edge 3 contacts with wheel rim, the outer rim coupling of profile and wheel rim.During as automobile inner tube, its shape is a planar annular, and the wall thickness of two annular hollow sleeve both sides can be greater than the wall thickness that contacts with the road surface, and concrete thickness is decided on different vehicle; During as bicycle tube, its shape is an annular cambered surface.
Uninflated inner tube of the present invention is by the amilan manufacturing.Amilan has characteristics such as high strength, high rigidity, high-flexibility, and after the intensifier that employing is commonly used such as glass fibre, carbon fiber etc. strengthened, it drew gentry's intensity, bending strength, strength under shock etc. all to improve more than the twice than pure resin.Uninflated inner tube can adopt conventional plastic injection moulding process machine-shaping.
Contrast Fig. 2 illustrates the stressing conditions of Uninflated inner tube of the present invention.The tube wall on outer ring hollow sleeve 1 both sides is a bearing surface, and its function is to support car body, the various live loads that produce when bearing the static weight of automobile and running car.Bearing surface is thicker, and its intensity is higher, and the fitting surface that is bearing in wheel rim is on the outer rim 3, arching distortion under loaded state.And the ground-surface contact surface (has cover tire between the inner tube of a tyre and the road surface, no longer explanation below) narrower, its rigidity is corresponding to be lower than bearing surface, elasticity is higher than bearing surface, wheel is met external force (as stone, pit etc.) collision by chance, convenient use elasticity, the bump of mitigation and road surface and external force has improved the stationarity of running car.When empty wagons parking or low speed driving, the outwards slight arching distortion of bearing surface, the inner tube of a tyre and ground-surface contact surface increase slightly, and the distance between outer ring hollow sleeve and the interior annular hollow sleeve is dwindled slightly; When running at high speed (80km/h), inner tube of a tyre deformation state alleviates.Fully laden stops down or during low speed driving, and the degree when bearing surface arching degree outwardly is a bit larger tham empty wagons is big during also than empty wagons with ground-surface contact surface, between outer ring hollow sleeve and the interior annular hollow sleeve apart from further dwindling; When running at high speed, the state the when inner tube of a tyre can return to the empty wagons low speed driving.During overload, the serious arching of bearing surface further increases with the ground-surface contact surface, and the outer ring hollow sleeve is pressed close to interior annular hollow sleeve, and interior annular hollow sleeve also plays a supportive role, and prevents that the inner tube of a tyre from damaging.
