Abstract
The utility model discloses a non-inflatable inner tube for vehicles. The structural design which is completely different from the prior art is adopted. The structural design is that the non-inflatable inner tube for vehicles is composed of cylindrical springs which are provided with unequal diameters and coiled into spiral shapes; the outer diameter of the spring is tightly matched with the inner diameter of a tyre cover. The non-inflatable inner tube for vehicles has the advantages that the non-inflatable inner tube for vehicles is consistent with the requirement for the elastic property of vehicle inner tubes; the inflation is not required, and the trouble for inflating an inner tube is omitted; when vehicles travel in high speed, traffic accidents can not occur because of exposed tyres caused by the expansion of the heating air in inner tubes and also has the advantages of high safety, convenient operation and long service time.
Description
The utility model relates to the general vehicle in the communications and transportation, is a kind of automobile-used non-inflatable tyre, specifically, is a kind of circumferentially non-inflatable tyre of the spiral spring of configuration of relative wheel shaft that adopts.
Over more than 100 year, after the vehicle such as bicycle, automobile came out, the tire overwhelming majority of vehicle was to be that material is made of cover tire and inflatable inner tube with rubber, as bicycle, automobile, trac., motor bike, armored motor car, aircraft etc.Inflatable inner tube wherein has many unsurmountable shortcomings, as the inflation trouble, is punctured by sharp objects easily, can blow out because of tire temperature build-up air pressure expands when running at high speed, and causes the horrible disaster of car crash.Even the tubeless tires of up-to-date appearance still need be inflated and can travel.
The purpose of this utility model provides a kind of inner tube of vehicles elasticity requirement that both met, and need not inflation again, vehicle inflation-free inner tyre safe and convenient to use, that the life-span is long.
Technical solution of the present utility model is: a kind of vehicle inflation-free inner tyre, it has adopted and the diverse structure design of prior art: constitute the external diameter of spring and cover tire internal diameter flush fit by being wound into the screw-shaped cylindrical spring.
Joining end to end of spring described in the utility model connects, and becomes annular arrangement.Spring is not for waiting gauge structure, and the big circle of two adjacent rings one circle is little.Spring by rectangle steel band, high-molecular wire rod or strip coil around forming.Gapped between every circle of spring.Certainly, also can adopt other suitable versions.
The utility model has the advantages that: both met the requirement of inner tube of vehicles elasticity, need not inflation again, deducted and given the gas filed trouble of the inner tube of a tyre, can not blow out because of the inner tube of a tyre air expanded by heating during high vehicle speeds gets into an accident, safe and reliable, easy to use, the life-span is long.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation that a kind of vehicle in the utility model is used inflation-free inner tyre;
Fig. 2 is the expansion scheme drawing that a kind of vehicle in the utility model is used inflation-free inner tyre.
Fig. 1, Fig. 2 have described an embodiment of the present utility model.A resilient spiral cylindrical torsion spring 1 is arranged in this embodiment, and spring 1 is wrapped in rubbery cover tyre 2 the insides, and its effect is basic identical with rubber inner tube.Spring 1 can be a material with metal or plastics, be shaped as the not isometrical torsion spring of annular arrangement, the metallic material that uses in the utility model can adopt have higher elastic limit, the high-quality spring steel of persistence, dynamic ductility and good heat treatment performance, as 65Mn, 60Si2Mn, 4Cr13,50CrYa etc.Dillies such as bicycle also can adopt nylon (PA), the polypropylene High molecular materials that resistance to heat is good, modulus of elasticity is high such as (PP).The utility model is wound into spiral cylindrical torsion spring after spring wire (round steel) draw down can being made steel band again.The external diameter of spring and cover tire internal diameter flush fit.Joining end to end of spring connects, and becomes annular arrangement.Spring is not for waiting gauge structure, and the big circle of two adjacent rings one circle is little, i.e. D
1＞D
2Gapped between every circle of spring.The length overall HO of spiral cylindrical torsion spring equals cover tire internal diameter overall circumference, and the two ends steel band is welded into the annular elastomeric spring coil.The width B of steel band and thickness d depend on the weight capacity of vehicle.Light wide of the heavy weight/HP ratio of load; Light thick of the heavy weight/HP ratio of load, to guarantee tire when bearing given load, it is low excessively to be unlikely to distortion or elasticity, keeps having good stable and traveling comfort in the vehicle '.The purpose of spring wire draw down is to prevent to lodge after spring is under pressure, and is ineffective.Its outer diameter D during wind spring
1Should with cover tire internal diameter flush fit, prevent that cover tire from losing the expansive force of spring inner tire, wheel hub when travelling (circle) displacement, slip even knocking over.D during wind spring
2Diameter compare D
1Little, its effect is to work as vehicle in motion, and cover tire is subjected to the load of vehicle to form pressure, and this pressure is delivered to spring inner tire spring D rapidly
1Get on D
1Can be delivered to left and right sides spring D very soon again after being under pressure
2Get on.D
1The back reduced that is under pressure is reversed the D on adjacent both sides
2When enlarged-diameter, wheel turn over this spot pressure, D
1Lose pressure, recover original diameter, D
2Narrow down to original diameter simultaneously and form elasticity.When vehicle stops to travel, same principle, D
1Reduced, D
2Enlarged-diameter is born all D of this part spring of pressure
1And D
2Equal diameters is born the pressure unanimity.After the vehicle ', spring returns to Fig. 1 shape.D
1And D
2The elasticity that differs greatly is big, D
1And D
2Diameter differs that little elasticity is little, and these all can make vehicle beat, jolt, and can't take advantage of seat and drives.And D
1And D
2Diameter differs hour, and the buffer wheel performance descends, and the cover tire wearing and tearing are accelerated.Spring steel band did not rub mutually to good when in addition, pitch t (axial distances between the two adjacent rings corresponding point) was with vehicle '.Pitch is crossed conference makes deflection of spring ineffective.Certainly, the utility model also can be processed into annular tube shapedly with cover tire simultaneously, makes the integrated use of Tire ﹠ Tube.
