Abstract
The present invention relates to a tubeless cycle tyre which is formed in a manner that after being coiled into shapes of accompanying drawings by spring wire, and the spring wire is bond to synthetic rubber. The appearance of the present invention forms a ridge shape, the center has an air cavity, and the bottom forms a bridge shape. The present invention has the characteristics of no inner tube, no inflation, small friction coefficient of running, eternal and stable elasticity and long service life. After being assembled once, the tubeless cycle tyre is not disassembled until the tubeless cycle tyre is waste, and the tubeless cycle tyre replaces the existing inflation cycle tyres.
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 tyres 3. crochet tires, and 4. tubular tyre 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, 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 not gas filed tubeless rickshaw tyre and implement method of the present invention, produce the not gas filed tubeless rickshaw tyre of all size.It is applicable to bicycle, Electrical Bicycle, child's bicycle, medical hand barrow, hand barrow, the various three-wheel vehicle of various models, and the manually driven tricycle for the disabled, is 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, the bottom is bridge shape, see 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. after the once mounting, 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 eternal.4. estimate to prolong 1.5-2 doubly than existing inflation cycle tire service life.5. its appearance and modeling has determined than the brisk agility of existing inflation cycle tire.6. because had an above-mentioned advantage, the slow lane magnitude of traffic flow unimpeded also played certain impetus.
Below in conjunction with accompanying drawing enforcement of the present invention is described in further detail: (1) is that the tubeless rickshaw tyre main body includes the exploitation silk as shown in Figure 1, and angle α is that 90 ° (2) are that spring wire (3) is that first machine screw (4) is that nut A is the center air chamber.(5) be pad.(6) be spring washer.(7) with (8) be the cord of the naked spring wire tire of bag bottom.(9) be assembly clearance.The connection close joint of tire two tip surfaces when (10) being assembling.(11) be to 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 °.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 the exploitation silk, and outward appearance is pentroof, and angle is 90 °.It has improved sidewall intensity, and it can dwindle the ground contact area of tire under certain load.Thereby it is brisk and quick to drive a vehicle, though temporarily also brought average unit area pressure to increase, the summit of tire body (1) is worn away easily.But, when driving, soon, just make the summit of tire body (1) wear away and the change circle rust.Ground contact area is corresponding to be increased little, and average unit area pressure is reducing day by day.So tire body (1) top abrasion loss is slowing down day by day.Moreover the used thickness that the actual used thickness of this tire body (1) surpasses existing tire is that decorative pattern thickness is more than 3 times.Thereby will prolong more than 1.5～2 times by this existing tire the service life of whole tire.Spring wire (2) is the skeleton 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, remainder pressure is relied on the characteristics of 90 ° of self angles, and 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, 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 in the bottom of tire.Fig. 2 is the front elevation of tubeless rickshaw tyre of the present invention two ends connecting bridge, in fitting process, pats all around, makes tire two tip surfaces (10) close joint not have height, guarantees 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 vital part of tubeless rickshaw tyre of the present invention, is formed by the spring steel 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. bear 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, requires 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.
