The used optimal resilience body of the present invention is polyurethane.
With reference now to Fig. 1, Fig. 2 and Fig. 3 of casehistory a preferred embodiment of the present invention,, represented among the figure to be installed on the wheel so that around 14 tire 10 that rotate.Tire 10 comprises an elastomeric material ring bodies 16 that has outer ring spare 18 on its outer peripheral edges, on the circular piece 18 wheel face 20 can be installed outside.An interior circular piece 22 is arranged on the inner peripheral of ring bodies 16, and interior circular piece 22 is bonding or be fixed on the outer ring surface 24 of wheel rim spare 12.Interior circular piece 22 is identical with outer ring spare 18 width on common axial direction, and common the extension.
Outer ring spare 18 by many around and isolated rib-shaped piece 28 and a spoke 32 are supported and damping, each rib-shaped piece 26 comprises one first axial component 28(Fig. 3) and second axial component 30, spoke 32 is flat in this embodiment of the invention, an one side 32a connects the first 28 of rib-shaped piece 26, and its another side 32b connects the second portion 30 of rib-shaped piece 26.
Rib-shaped piece 26 extends axially (Fig. 3) along interior circular piece 22 and outer ring spare 18 usually, in preferred embodiment shown in Figure 1, rib-shaped piece 26 is for the angle A (Fig. 1) of one 15 ° to 75 ° of the sagittal plane R inclinations of intersecting at rib-shaped piece 26 and place, interior circular piece 22 joint portions and rib-shaped piece 26.(not shown) in another embodiment, rib-shaped piece 26 can radially extend, and does not have leaning angle A, and one 0 ° to 15 ° smaller angle is perhaps arranged.Spoke 32(Fig. 3 in the present embodiment) is positioned at and the perpendicular plane of the turning cylinder of tire 10.
In the preferred embodiment that is shown in Fig. 1～3, primary shaft to the rib-shaped piece part 28 and the second axial rib-shaped piece part 30 each all with identical angle tilt in radial inner end place and their sagittal plane R of intersecting at them, but 28 pairs of firsts radially the leaning angle direction of plane R is preferably opposite with the leaning angle direction of second portion 30.Therefore, as seen in Figure 3, the first rib-shaped piece part 28 is from upwards continuity and connect outer ring spare 18, the second rib-shaped piece parts 30 circular piece 22 from section line continuity downwards and in connecting of section line.
The ring bodies part 16 of tire 10 preferably forms with the size that falls into broad range, preferable range and optimum range, size relationship and angular relationship in being listed in the table below:

In above-mentioned table 1, different projects refers to the identical accordingly size or the angle of Fig. 1～3 illustrated, and further is defined as follows: γ
0External diameter for ring bodies 16, A is the leaning angle that rib-shaped piece 26 is become with sagittal plane R, di is the radial wall thickness of interior circular piece 22, do is the radial wall thickness of outer ring spare 18, L is the length along angle direction of rib-shaped piece 26, D is the radial distance from the outside face of interior circular piece 22 to the inside face of outer ring spare 18, dw is the axial width of spoke 32, rib-shaped piece 26 thickness that ds records for the vertical direction in length L, ti is the axial length of interior circular piece 22, to is the axial length of outer ring spare 18, and γ i is the radial dimension of interior circular piece 22 inside faces.
In the tire of Fig. 1～3 shown types, although have the cited parameter of top table 1, rib-shaped piece 26 mainly is a compressive deformation owing to the influence of spoke 32 is restricted to.Spoke 32 can be cast into integral structure.Spoke 32 tends to prevent rib-shaped piece 26 flexural deformations, and effect is to have increased structural rigidity widely.In addition, rib-shaped piece 28 tends to prevent spoke 32 in axial press-bending, so rib-shaped piece and spoke work synergistically together and load with load supporting tire.
Tire 10 is that its moulding and the demoulding are much easier, and the type that does not need to change manufactured materials just can have different spring rate (by changing the leaning angle of rib-shaped piece 26) with respect to the advantage of airless tire in the prior art.This rib-shaped piece leaning angle that utilizes is to change spring rate and can not need to increase the compressive strain of rib-shaped piece greatly and to finish.Though the buckling strain meeting of rib-shaped piece root increases, these strains can utilize the rib-shaped piece 26 and the notch 34 of the suitable radius at the place, joint portion of interior circular piece 22 and outer ring spare 18 to reduce as far as possible.Preferably, the radius in rib-shaped piece 26 and the acute angle joint portion of interior circular piece 22 and outer ring spare 18 is about 1/8 to 1/2 inch, and the radius of rib-shaped piece 26 and the joint portion, obtuse angle of interior circular piece 22 and outer ring spare 18 is about 1/4 to 1 inch.
Tire of the present invention is that it is sealed performance ratio prior art structure and will improve manyly with respect to the remarkable advantage of prior art structure.The rib-shaped piece structure can be out of shape or bend partly, and because distortion obtains load bearing capacity, thereby make the outer ring spare that holds Uneven road can resemble very much an air-inflation tyre.The prior art structure has very little local flexibility usually, and distortion must disperse their deformation in order to obtain quite low spring rate.
The term of Shi Yonging " bending " is defined as the unexpected and violent relatively deformation that produces as the compressive load that surpasses certain critical loading value (being called Pcr later on) herein.
With reference now to Figure 23,, it illustrates the part when tire tire 10 of the present invention when run duration bears normal load on slippery traffic surface.Load forces on the tire is approximately 800 pounds (363 kilograms).The rib-shaped piece 26 of the most directly loading on the supporting tire is just bearing a kind of compressive load, and this load has in fact shortened the total length of that rib-shaped piece.In graphic shape, do not have long 1.12 inches (2.84 centimetres) of rib-shaped piece of load, and long 0.99 inch (2.51 centimetres) of rib-shaped piece of load are arranged.
When rib-shaped piece 26 when the tire run duration bears compressive load, spoke 32 is compressed and shears two kinds of power, even may be stretched.But spoke 32 and rib-shaped piece 26 mutual actions are with load diversity power, and rib-shaped piece 26 obviously only bears compressive force basically.It should be noted that rib-shaped piece and spoke are not used for bearing load when bending.
With reference now to Figure 24,, it illustrates tire 10 and has run into situation in the rough process having loaded 1450 ft lbfs (658 kilograms).The most directly the rib-shaped piece 26 of supporting tire load has born and has surpassed its critical loading value P
CrLoad, and bent.Adjacent rib-shaped piece will carry the load that increases, but can not bend, because load does not also reach P
CrThe ability of this local bending of rib-shaped piece 26 of the present invention makes outer ring spare can hold Uneven road at normal tire run duration, and resembles slightly and work the inflated wheel tyre surface.
The applicant has been found that if the structure of rib-shaped piece 26 makes it reach P when the total load on the tire 10 makes tire be compressed the deformation that produces tire cross-section height 6% to 12%
Cr, airless tire 10 is with the most approaching airtyred travelling characteristic so.This means that when tire bore 6% the load of desired amount between 12% that makes the initial tire cross-section height of tire cross-section height (distance from interior circular piece 22 to outer ring spare 18) compression, the localised load rib-shaped piece had just reached P

Compare one of purpose of the present invention with conventional air-inflation tyre and provide a kind of weight gently as the less tire of spare tyre storage space.The applicant has been found that, if the ratio of material cumulative volume (space that is occupied by tire material) and total projection volume (space between circular piece outside face and the interior circular piece inside face outside) is between 20% to 60%, the purpose of these spaces and weight is easy to reach.In the present invention, this volume ratio can be partly owing to using the rib-shaped piece that mainly bears compressive load to reach.The orientation of rib-shaped piece has been utilized many elastomeric materials desirable performance when bearing compressive load among the present invention.
The characteristic that another hope of airless tire or any tyre possesses is the proof resilience rate that changes with the road surface types that loading of tire contacts.Specifically, people wish, spring rate is little on can be than flat road surface when running into bump pad or block material.In the present invention, the desired proportion of the spring rate on the wide block material of the spring rate on the flat road surface and 1/2 inch (1.27 centimetres) is between 1.4 to 4.0.This be the present invention described herein can reach.
With reference now to a kind of method for optimizing of making tire 10 of Fig. 4 and Fig. 5 description,, this method is utilized one usually with 40 moulds of representing.Mould 40 comprises the outer modular ring 42 and two templates 44,46 that limit ring bodies 16 sides that limit tire outside diameter.Template 44 has been adorned many plug-in units 48, and they removably are fixed on the template 44 with bolt 50.Plug-in unit 48 is generally rhomboid, around and apart from one another by placing on ground, thereby at first axial component 28 that between plug-in unit, forms rib-shaped piece 26 during the forming operation.
Equally, template 46 has been adorned many plug-in units 52, and they are fastened on the template 46 with bolt 54, and plug-in unit 52 is generally rhomboid, around and apart from one another by placing on ground, to form second axial component 30 of rib-shaped piece 26.The internal diameter of ring bodies 16 is determined by the periphery 24 of wheel rim 12.
Used suitable paired ring plain inner washer 56 and ring plain outer washer 58, inner washer 56 be used for making template 44 and 46 and the radial flange of wheel rim 12 separate, outer washer 58 be used for making template 44 and 46 and outer modular ring 42 separate.The axial width of packing ring 56 and 58 axial width decision spoke 32, these thickness can change with the design condition of ring bodies 16.
Equally, when hope changed the angular orientation line of rib-shaped piece part 28 and 30 or thickness according to the design variation wanted, plug-in unit 48 on the template 44 and the plug-in unit 52 on the template 46 can be removed, and with corresponding difform plug-in unit replacement.Inlet pipe 60 is used in mold charge operating period from material source (not shown) to mould feed fluid material, and freeing pipe 62 is used for removing air from mould during loading operation.
Modular ring (not shown) replaced wheel rim 12 in the another kind of method of making ring bodies 16 was used, and the shape of interior modular ring is similar to outer modular ring 42, but has less respective diameters.In this another kind of method, after ring bodies 16 moulding and after cure, ring bodies 16 must be glued on the aluminium wheel rim that processes with the polyurethane adhesive.
