Abstract
Tubeless rickshaw tyre of the present invention constitutes with neoprene is glued together after being coiled into the accompanying drawing shape by spring wire.Outward appearance is pentroof, and there is air chamber in central authorities, and the bottom is bridge shape.Characteristics: inner tube free, never inflation, friction coefficient is little during driving, and elasticity is eternal stable, and long service life once after the assembling, is used and is just unloaded when scrapping, and it will be replaced in existing inflation cycle tire.
Description
The invention belongs to a kind of not gas filed cycle tire of the inner tube of a tyre that do not have, is to be replaced in existing inflation cycle tire.
At present, generally the cycle tire of Shi Yonging all is the cycle tire that gas filed Tire ﹠ Tube is used in combination, not gas filed tubeless rickshaw tyre still is a blank, " rubber industry handbook " the 4th fascicle " tire ", second piece of cycle tire in December, 1989 the first edition, Beijing first impression, Chemical Industry Press publishes.The cycle tire of having discussed present use in detail has four kinds: 1, beaded-edge tire.2, straight-side tyre.3, crochet tire.4, tubular tyre.It all is the cycle tire that gas filed Tire ﹠ Tube is used in combination.It must be inflated, after the inner tube of a tyre is poked, and necessary tire patching, inflation could be used.Especially the tire of making amends for one's faults originally in summer, because the temperature height, the reason that scald on the road surface is come unstuck easily and is leaked gas, people have often spent a large amount of time, financial resources and labour for again and again tire patching, inflation.
The objective of the invention is to propose a kind of manufacturing not gas filed tubeless rickshaw tyre method and implement method of the present invention, produce the not gas filed tubeless rickshaw tyre of all size.It is applicable to bicycle, the Electrical Bicycle of various models, child's bicycle, medical hand barrow, and hand barrow, various three-wheel vehicles, and manually driven tricycle for the disabled are replaced in existing gas filed cycle tire.
In order to achieve the above object, the present invention adopts after spring wire coiled Fig. 3, Fig. 4 shape glued together with neoprene, and its outward appearance is pentroof, and there is air chamber in central authorities, and the bottom is bridge shape, sees Fig. 1.Two ends couple together, and see Fig. 2.On the basis of existing manufacturing cycle tire cover tire, improve old technology, increase new process, can implement the not production of gas filed tubeless rickshaw tyre of the present invention.
The advantage of tubeless rickshaw tyre of the present invention: 1, once by behind the dress.Exhaust when scrapping up to value of service and just to unload, need not dismounting in the whole used life and repair.2, inner tube free is thoroughly eliminated gas leakage, tire patching, and phenomenon such as flat, as to blow out is not afraid of simultaneously and is poked.3, never inflation, elasticity is wall forever.4, estimate to prolong 1.5-2 doubly than existing inflation cycle tire service life.5, its outward appearance appearance has determined than the brisk agility of existing inflation cycle tire.6,, the slow lane magnitude of traffic flow unimpeded also played certain impetus because had an above-mentioned advantage.
Below in conjunction with accompanying drawing enforcement of the present invention is described in further detail: as shown in Figure 1,1, be that the tubeless rickshaw tyre main body includes exploitation silk, angle α is 90 °.2, be spring wire.3, be first machine screw.4, be nut.A is the center air chamber.5, be pad.6, be spring washer.7 and 8 is cords of the naked spring wire tire of bag bottom, the 9, be assembly clearance, the 10th, and the connection close joint of tire two tip surfaces during assembling.The 11st, be engaged the wheel rim that uses tubeless rickshaw tyre.Fig. 2 is the two ends connection diagram that is assembled in the tubeless rickshaw tyre on the wheel rim.Fig. 3 Fig. 4 is the front elevation and the lateral plan of spring wire.Angle β is 30 °, and M is a span, and S is a pitch, and D is a diameter, and L is the girth of tire.
Tubeless rickshaw tyre main body 1 includes an exploitation silk outward appearance and is pentroof, when angle is 90 ° of drivings and the ground friction face only be the summit of angle.Mechanics principle is told us, and friction face is little, and friction coefficient and friction force are also little, and the resistance to air is also little simultaneously.Spring wire 2 is skeletons of tubeless rickshaw tyre, angle is 30 °, it and tire body 1 are glued together, A is the center air chamber, when driving had load, the angle summit of tire body directly was under pressure, and most pressure is relied on the interior exploitation silk of tire body and the elastic force of spring wire and the effect of bounce and born, all the other partly pressure rely on the characteristics of 90 ° of self angles, pressure is disperseed.If the diameter D of spring wire is identical with the wheel rim spoke, pitch S is identical with wheel rim spoke neighbor distance, so, and the pressure that spoke can bear.It is more than sufficient that the main body of tire includes the spring wire of developing silk and being glued together.Rely on center air chamber A,, be enough to make tubeless rickshaw tyre main body and spring wire to be under pressure and produce the needed space condition of elasticity though there is not air pressure.The span M of spring wire is wrapped naked by cord, just to be bridge shape be that tire is under pressure and the backing that produces elastic force guarantees, Fig. 2 is that tubeless rickshaw tyre of the present invention two ends connect front elevation partly in the bottom of tire.In fitting process, pat all around, make tire two tip surfaces 10 close joints not have height, guarantee the no jumping phenomena of driving, 9 should leave the space, serve as a contrast Upper gasket 5 then, with first machine screw 3, penetrate the tire pre-manufactured hole, shell tool 5 puts spring washer 6, and nut 4 is firmly screwed.Fig. 3 is the key part in addition of tubeless rickshaw tyre of the present invention, is formed by the spring wire coiling.Pitch S and diameter D determine that according to operating needs length L is the girth of tire, possess tire and bear the indeformable ability that still keeps favorable elasticity behind the pressure.Rule of thumb analyze angle be decided to be 30 ° comparatively suitable.See Fig. 4.Span M is slightly wideer than cooperating rim width, selects appropriate tolerance on fit.To guarantee that flush fit gets final product.
The embodiment of tubeless rickshaw tyre of the present invention is undertaken by second piece of described scheme of cycle tire of " rubber industry handbook " the 4th fascicle " tire " in principle, just following new technology has been replaced in incompatible old technology just.
1, bears load design drafting tubeless rickshaw tyre shop print of the present invention according to wheel rim specification and tire.
2, draw the mould drawing according to the shop print design of tire, press figure die sinking tool then.
3, bear load according to wheel rim specification and tire, select the material mark of spring wire, the diameter D of spring wire, the pitch S of coiling, and span M, length L, shop print is drawn in design.Require to determine processing technology according to drawing then.
4, tubeless rickshaw tyre principle according to the present invention is determined tire machining process route, technology essential factors such as rubber compounding.
5, the demoulding becomes tubeless rickshaw tyre of the present invention.
After tubeless rickshaw tyre of the present invention is made, can cooperate the wheel rim assembling to use.
