Description

A kind of novel inner tube free non-inflatable tyre

The utility model relates to a kind of inner tube free of making the tire flexibility load-bearing skeleton with spring wire and does not inflate novel tire.

Make the tubeless tires of load-bearing skeleton with elastic wire, though by Shi Miaosheng (1992), Zhang Baowang (1993) etc. proposed, but on market, promote the use of seldom up to now, its reason key is these new patented technology schemes that proposed, in actual production and use, all also there are some such-and-such problems, thereby the patent technology popularization that these that make have proposed uses and is difficult for, though I also once declared a kind of paliform that adopts lonely type steel wire of arranging in June, 98, tubeless tires (98114535.3) as load-bearing skeleton, but its range of use, mainly only be applicable to bicycle, motor bike, light-duty vehicles such as three-wheel vehicle are difficult to not add modification and are applied to automobile, truck conspicuity markings such as trac..So design also proposes the better more practical tubeless tires technical scheme that a kind of degree type vehicle can be used, and remains very necessary.

The purpose of this utility model, the various tubeless tiress that a kind of ratio has now proposed will be proposed exactly, all the better and field of application of structure uses the new tubeless tires structure technology scheme of elastic wire load-bearing skeleton widely, so that make with the novel tubeless tires of elastic wire, can on market, obtain wide popularization and application early as load-bearing skeleton.In order to achieve the above object, the utility model is achieved through the following technical solutions:

(1) with the monnolithic case structure of tubeless tires, square section by Zhang Baowang is the closed circular tubulose, and the up-small and down-big oblate pipe spring-like of Shi Miaosheng, be improved to the square section as the ordinary motor vehicle cover tire, be the nearly Ω shape loop shaped (see figure 1) of opening to the inside, its manufacturing process just can be simplified greatly like this, installs with use also more convenient.

(2) improved the frame mode of main body elasticity load-bearing skeleton in the tire, made it big or small round steel circle combination,, become the class Ω shape feature (1) similar with common locomotive cover tire external form with the up-small and down-big near semicircle spring loaded of Shi Miaosheng by Zhang Baowang.And its manufacture method also by last declare patent at first make fence and fire grate shape, change into the nearly Ω shape independence ring of at first making one by one, to a large amount of these independent nearly Ω shape rings then, continuously intensive is placed into process within the tire side by side, use and the approaching isometric great circle tight loop (2) of Wheel, all nearly Ω shape standalone elastic rings are connected to a complete integral body (as Fig. 2), form the elasticity load-bearing skeleton jointly.

Owing to make the spring wire of this elasticity load-bearing skeleton, can select the type of arbitrary diameter for use, so as long as select the spring wire of different thicknesses for use by calculating or experiment according to the load-bearing needs, just can make the elasticity load-bearing skeleton that suitable various tyres of different types use, and further produce the practical tubeless tires that adapts to various different needs.Vehicles such as bicycle, motor bike, three-wheel vehicle for example, the required weight capacity of its tire is less, makes than the spring wire of subclass type so its elastic wire load-bearing skeleton just can use relatively.Used tires such as small passenger car, farm vehicle, small-sized passenger and freight car and trac., required weight capacity increases greatly than bike tyre etc., thereby processes the diameter of the required spring wire of these tires, also just must heighten greatly slightly than bicycle etc.And used tire on the heavy-dutys vehicle such as large truck, engineering truck, its bearing capacity that needs is very big, makes their elasticity load-bearing skeleton naturally, and required spring wire also just must be very thick.

Make elasticity load-bearing skeleton in addition than required tire on the heavy-duty vehicle, except can adopting the method that increases required spring wire diameter, another measure that also can take, be exactly with the nearly Ω shape load-bearing steel wire ring in the elasticity load-bearing skeleton, arrange by in carcass, adopting individual layer, change two layers or more (see figure 4) of arranging continuously into, after adopting such method, its weight capacity of producing tire can increase exponentially.And use the vehicle of such tire, running stationarity also can be better than the tire that uses same weight capacity individual layer elastic wire load-bearing skeleton.When on heavy-duty vehicle, using tubeless tires, a kind of method that can also adopt, it is exactly the deadweight during according to the vehicle empty wagons, at first design an overcoat tire (5) that supporting power is less, and according to the weight of the general institute of particular vehicle roping goods, make an assistant spring liner support (see figure 5), then overcoat tire (5) and flexible liner support (6) together are contained in (see figure 6) on the particular vehicle rim for automobile wheel.When the vehicle empty wagons that overcoat band and liner support are housed travelled, vehicle mainly utilized the resilient support of overcoat band to run, and after drawing weight, the auxiliary liner support just can with the total weight of overcoat tire together support vehicle together and goods.Like this this class vehicle, just when empty wagons and load-carrying all very pulsation-free run.

In each figure, all can find out in addition, the top of nearly Ω shape steel ring in the main elastic wire load-bearing skeleton of tire of the present invention, less curved downwards hang down (3) are all arranged, carrying out design-calculated implication like this has two: one, in order to lower the height of elastic wire load-bearing skeleton, because for weight capacity and the stability that increases the elastic wire skeleton, each nearly Ω shape bead coil in the elasticity load-bearing skeleton all can be made up-small and down-big form, in this case, center of top is made downward less curved hanging down, and just can lower the absolute altitude of steel ring naturally.The 2nd, in order to increase the stability of load-bearing skeleton when being under pressure.But this curved downwards hanging down though all paint in each figure, is not that load-bearing skeleton is necessary, so can remove yet.

(3) tire can be subjected to very big front and back twisting application force, and this front and back twisting application force is to have detrimental effect to tire as not eliminating when double ring ahead and slowing-down brake.In order to overcome this front and back twisting application force of tire when quickening and brake, in the rubber material layer in the present invention outside in the elasticity load-bearing skeleton, also designed a stable net that prevents the twisting of tire front and back.This stable net, can adopt the wirecord fabric inside and outside respectively to add one deck serves as, also can adopt than the hairspring steel wire, be processed into the long U-shaped circle that a large amount of width are slightly larger than the elasticity load-bearing skeleton, the comparatively dense oblique of one deck hypsokinesis of then these long U-shaped circle one decks being leaned forward is arranged in the outside of elastic wire load-bearing skeleton, forms to stop the oblique of tire improper front and back twisting to stablize the stratum reticulare (see figure 3).Such oblique is stablized net, owing to just in time be positioned within the carcass of tire than the outside, its existence just has the effect that stops front and back twisting application force infringement tire.In order to increase stabilizing effect, inside and outside this stable net, also can increase the steel wire reinforced rib of vertically arranging on a small quantity more in addition.And when using on dilly tires such as bicycle, stable net also can be reduced to a spot of vertical arranging steel wire reinforced rib.

(4) normal tube-tyre, generally be to utilize tire inner tube to inflate the effect of outer support, cover tire is fixed on the wheel rim, and tubeless tires of the present invention owing to do not re-use is inflated the inner tube of a tyre, institute thinks interfixes tire and wheel rim, generally should adopt to add the internal fixation circle on the wheel rim, after putting tubeless tires, add screw and make tire and internal fixation circle tighten fixing method then.On this tubeless tires, generally all should make screw hole (7) for this reason.Also can adopt the outer bullet application force of tire inner spring steel wire in addition, and inside and outside two folders protect that mounting ring folds etc., and method is fixed.But when such method twists application force before and after tire is subjected to greatly, be difficult to prevent that tire relative wheel circle from skidding, so not as using the screw good fixing effect.

Tubeless tires of the present invention after making according to the aforementioned techniques scheme, just can equally with tube-tyre have been used.But this novel tubeless tires is in use, will improve than the very big amplitude of existing tube-tyre performance, its concrete characteristics have following some:

1, will use after the once mounting always scrap till, midway needn't laid-up.

2, forever needn't be worried for often inflating.Also never because of pricking threatened abortion gas, infringement highways such as day thermal explosion tire are imposed a fine and suffer the highway administration personnel.

3, the comparable tube-tyre of elasticity improves, no matter and the road conditions quality, the vehicle that all can guarantee to use it runs than with tube-tyre the time more stably.

4, how many productive costss can not increase than tube-tyre, and production technology can not gone than tube-tyre complexity thereunto yet.

5, will increase than the big spoke degree of tube-tyre the service life of tire.

6, this tubeless tires, owing to itself have better elasticity, so when using this tubeless tires, alleviate the relevant shock absorbing apparatus elasticity requirement of vibrations with vehicle, also comparable existing design weakens, to prolong its normal service life.
