Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 2, traditional non-inflatable tyre is the disc 2 by being made up of elastomeric material, stay bearing plate 3, inner ring 1 and outer shroud 4 form, in the present embodiment, elastomeric material is polyurethane material, disc 2 in the process of composition, stay bearing plate 3, the angle of different angles can be there is in the connection intersection of inner ring 1 and outer shroud 4, and the higher polyurethane of hardness is a kind of material with elasticity not easily warpage, particularly when polyurethane as more need during supporting role polyurethane have larger hardness could ensure in the quality not increasing more polyurethane support intensity, otherwise the weight of non-inflatable tyre will be allowed to increase energy consumption when vehicle travels strengthen and lose meaning, simultaneously polyurethane is also the valuable material of a kind of price comparison, therefore weight polyurethane is heavier, whole non-inflatable tyre cost is also higher, because disc 2, stay bearing plate 3, connecting place between inner ring 1 and outer shroud 4 can form angle, a region of making a concerted effort can be formed after angle is formed, and due to the hardness of polyurethane higher, so the polyurethane in this region of making a concerted effort is bearing downwards, left, to the right or the bearing force in any direction can strengthen at double, particularly disc 2 is perpendicular to outer shroud 4, and the left and right of disc 2 is all strengthened connecting by stay bearing plate 3 and is extended same outer shroud 4 compact siro spinning technology and is integrated, according to mechanics principle, a region fixed very much can be formed around disc 2 and outer shroud 4 junction, and can be one and bear the maximum region of supporting capacity, according to mechanics principle, the ability to bear of the outer shroud 4 of close disc 2 junction can be several times of the holding capacity of the outer shroud 4 away from disc 2, and like this will allow the elastic force of non-inflatable tyre can each point or each region not identical, according to the general knowledge of those skilled in the art, inflated rubber tire when ensure outer shroud 4 thickness close to, the elastic force of local is substantially identical, when clearing the jumps, local can be surrendered rapidly uniformly, thus there is comfort, if instead each region of tyre surface bear the ability of gravity inconsistent time, non-inflatable tyre is easily out of balance in operational process, vehicle not only can jolt, but also can rock.
As shown in Figure 1, by arranging annular intermediate groove 41 in the middle of the whole annular of polyurethane outer shroud 4, protrude from the inside face of outer shroud 4 bottom annular intermediate groove 41 and be connected with ring-type disc 2, namely the formation of this annular intermediate groove 41 is not cause by middle outer shroud 4 is thinning, but ring-type disc 2 is shortened formed, the end points of the ring-type disc 2 shortened is near outer shroud 4, the middle outer shroud 4 of whole outer shroud 4, is finally all connected together gradually near the end points of the ring-type disc 2 shortened when keeping outer shroud 4 thickness constant.By arranging annular intermediate groove 41, can make to diminish and dispersed near outer shroud 4 bearing capacity of disc 2 junction in traditional non-inflatable tyre, now, connect the disc 2 of outer shroud 4 become two tilt only play connection functions and do not allow material annular intermediate groove 41 cell wall that is destroyed, and the cell wall tilted in two, the direction of gravity does not play main support effect, even if the application force playing part support has also forwarded rapidly outside annular intermediate groove 41 and outer shroud 4 region be connected with annular intermediate groove 41 to, like this, as many asly bearing capacity is dispersed to whole outer shroud 4, thus make the screen resilience in each region point can reach consistent as far as possible.
In addition, arrange in the process of annular intermediate groove 41, because stay bearing plate 3 is still connected with annular intermediate groove 41, therefore in whole tire construction, there is not destructive change in structural strength.Because outer shroud 4 adopts polyurethane material to make, its hardness is higher, shore hardness is more than 80 °, because polyurethane material hardness is relatively harder, its wear resisting property can be better, and there is the hardness of the rubber filling gas tyre of outstanding comfort shore hardness about 65 °, Comparatively speaking the traveling comfort ensureing that polyurethane outer shroud 4 has had in loads driving process is wanted, the outer shroud 4 of polyurethane will there is suitable susceptibility in kiss the earth region, and the hardness of the more abundant rubber tire of the hardness of polyurethane outer shroud 4 wants much hard, therefore polyurethane outer shroud 4 can be thinning, thinning benefit can also alleviate the lower load of wheel, and just because of although the annular intermediate groove of polyurethane outer shroud 4 41 is still ined succession mutually every bar stay bearing plate 3, then non-inflatable tyre is in carrying weight driving process, the antagonistic force of outer shroud 4 kiss the earth can be communicated near zone by a point, be communicated in total rapidly by this region again and go, just as inflated rubber tire by air as the effect of medium at identical reception and registration pressure pressure.The polyurethane that shore hardness is more than 80 ° has the wear resisting property more excellent than rubber, higher tear strength and percentage elongation and durometer level is wide, polyurethane outer shroud 4 can be relative thinning (contrast rubber tread), and can have good wear resisting property and tear strength, and the support strength of strut member also can meet the requirements simultaneously.Therefore, thinning by outer shroud 4, on the basis keeping original polyurethane wear resistant performance, can reduce costs on the one hand, also can increase comfort on the other hand.
And annular intermediate groove 41 is set also has another benefit, namely by arranging annular intermediate groove 41, outer shroud 4 is made to be divided into a left side, right outside ring 4, left, right outside ring 4 also can regard two tires be connected as, when kiss the earth, outer shroud 4 originally becomes left with the position of earth surface by middle distance tire center of circle outer shroud 4 line farthest, right two distance tire center of circle outer shroud 4 lines farthest, outer shroud 4 line ground contact area is still very little, but the shaded area formed between two outer shroud 4 lines is large, the cling property of whole tire improves greatly, more steady during tire ground connection, the brake active distance of tire obviously shortens.
For optimizing the traveling comfort of polyurethane outer shroud 4 further, outer shroud, except arranging annular intermediate groove, also arranges inner annular recess, and inner annular recess comprises outer shroud transverse concave groove and outer shroud longitudinal fluting; Outer shroud transverse concave groove is mainly arranged on the outer ring outer surface after the extension of every bar stay bearing plate and outer shroud intersection, namely the bottom of outer shroud transverse concave groove is connected with stay bearing plate, the depth of outer shroud transverse concave groove is arranged according to the thickness of outer shroud, the degree of depth of the thickness thicker outer shroud transverse concave groove of outer shroud can arrange darker, otherwise more shallow, outer shroud longitudinal fluting parallel or not parallel with annular intermediate groove 41 and non-intersect or connect, crossing.Described outer shroud longitudinal fluting 42 bottom land all protrudes from the inside face of outer shroud 4, and the cross section of described outer shroud longitudinal fluting 42 takes the shape of the letter U or V-arrangement shape.In addition, outer shroud longitudinal fluting 42 is all crossing with the outer shroud transverse concave groove above stay bearing plate 3, in order to reach better Comfortable elastic effect, the degree of depth of the depth ratio outer shroud transverse concave groove of outer shroud longitudinal fluting wants dark, and the axial plane place of outer shroud longitudinal fluting, outer shroud transverse concave groove and stay bearing plate connecting position is in the crenel structure be connected.
Allow polyurethane material not only for as while stay bearing plate 3 but also as outer shroud 4, save material and keep good load again, then the hardness of polyurethane material need more than 80 ° of shore hardnesses, but the situation lower supporting plate 3 high at material hardness is surrendered with the stressed difficulty in region of making a concerted effort that outer shroud is formed, particularly during pavement roughness, when outer shroud 4 drives through protruding little obstacle, because outer shroud 4 hardness is large compared with the hardness of inflated rubber tire, therefore position external annular surface face not contacting obstacle also can form actv. support to the position of contact obstacle, the outer shroud 4 contacting little obstacle is difficult to surrender, and by arranging inner annular recess 42, when outer shroud 4 is when by little obstacle, the inner annular recess 42 on outer shroud 4 both sides reduces the bearing capacity of the hard outer shroud 4 not touching obstacle side, namely under gravity, the groove cell wall compression of contact projection obstacle at first shortens, neighbouring inner annular recess or the groove-bottom of annular intermediate groove shoal, further again, because stay bearing plate 3 is closely connected with outer shroud, when gravity flattens outer shroud plane, stay bearing plate 3 and outer shroud planar shaped are in an angle, the stay bearing plate tilted is connected with the outer plane of a loop of pressing, the stay bearing plate 3 that non-crenel structure division is corresponding,
By gravity extruding, outwards plane of a loop bends at first, again pressure is passed to the stay bearing plate 3 below crenel when there being larger gravity extruding to pass over, also by gravity extruding, outwards plane of a loop is bending for stay bearing plate below crenel, this situation is the same with inflated rubber tire, the little easily yield deformation of screen resilience of local produces comfortable, and integrally-built screen resilience is very large, be not easy to allow whole circular tire be deformed into ellipticity.By adopting this outer ring structure, non-inflatable tyre produces in the process of moving has comfort and better load, also make tire rotational speed faster, and power consumption is less simultaneously.
In order to improve the yield deformation performance of stay bearing plate 3 further, arrange more than two and opposing parallel outer shroud longitudinal fluting and outer shroud transverse concave groove intersect, the degree of depth of the depth ratio outer shroud transverse concave groove of outer shroud longitudinal fluting wants dark, the axial plane place of outer shroud longitudinal fluting, outer shroud transverse concave groove and stay bearing plate connected position in the crenel structure be connected, the crenel nadir arc with the nearlyer connecting place of stay bearing plate extend to vertex again arc extend to the even thinning formation in stay bearing plate place little chase of curve of crenel nadir.The degree of depth of the little chase of curve is between the 10%-35% of stay bearing plate 3 thickness, width is between the 30%-150% of stay bearing plate thickness, so when carrying weight, stay bearing plate 3 has the easier yield deformation in the place of curve chase 21, stay bearing plate again below further compression line chase, thus make tire when stressed, produce better traveling comfort.
As shown in Figure 4, outer shroud 4 is separated into multiple outer shroud tread blocks 43 by annular intermediate groove 41, outer shroud transverse concave groove and outer shroud longitudinal fluting, outer shroud tread blocks first kiss the earth connected by groove cell wall and support in tire running process, when ensureing outer shroud tread block thickness and resistance to abrasion, the inside face hollow out of outer shroud tread blocks, hollow out position is inverted pot shape structure 431, wherein, this pot of shape structure " pot " end, is in the inside of outer shroud tread blocks, and the aperture position of " pot " is positioned at the inside face of outer shroud.During carrying weight, the side that " pot " shape structure of outer shroud tread blocks inside first extends to " pot " by " pot " end produces self compressive deformation, and because inversion " pot " structure of each outer shroud tread blocks inside is independently, therefore be firmly not easily destroyed, and due to the side of pot shape structure be just the cell wall of annular intermediate groove, outer shroud transverse concave groove and outer shroud longitudinal fluting, these structural systems are closely connected, and has again fabulous entirety survivable fastness during the Comfortable elastic that guarantee outer shroud tread blocks produces.
Further improvement, as shown in Figure 2, left outside ring and right outside ring are respectively provided with at least one outer shroud longitudinal fluting 42, and the inner annular recess quantity on left outside ring and right outside ring is equal and symmetrical, inner annular recess 42 is opposing parallel with annular intermediate groove 41 or be arranged in parallel, the depth of outer shroud longitudinal fluting 42 changes at different parts, outer shroud longitudinal fluting between the stay bearing plate that left outside ring or right outside ring two pieces are adjacent is in middle shallow, both sides are dark, and groove is deepened gradually by the stay bearing plate of centre portion to both sides, and the thickness of outer shroud is also thickening gradually to the stay bearing plate on both sides by centre, and corresponding outer shroud tread blocks hollow out is more and more darker, two pieces of adjacent stay bearing plates and between inner annular recess 42 and outer shroud tread blocks connect into arch configuration 5, the outer shroud of this arch configuration 5 midway location is thinner, and the outer shroud of end positions is thicker, the hollow out degree of the outer shroud longitudinal fluting 42 and outer shroud tread blocks that are simultaneously positioned at this position also produces corresponding adjustment along with the change of outer shroud 4 thickness, namely its groove of position that outer shroud 4 is thick is darker, its outer shroud tread blocks hollow out is also darker, and thin its groove of position of outer shroud 4 is more shallow, the hollow out of its outer shroud tread blocks is also more shallow, in this tire running process, both fine load carrying behaviour had been ensured, turn increase the traveling comfort of traveling simultaneously.
As shown in Figure 3, the size of the cambered surface angle of arch configuration 5 by the Distance geometry between adjacent stay bearing plate in opposite directions the thickness of stay bearing plate and the thickness of periderm decide, two pieces of adjacent stay bearing plate distances are shorter, and arch configuration 5 cambered surface angle can be larger, adjacent supports plate thickness is thicker, and arch configuration 5 cambered surface angle can be larger, periderm is thicker, arch configuration 5 cambered surface angle can be larger, because polyurethane non-inflatable tyre supports by material structure, the more thickness of stay bearing plate quantity is thicker and periderm is thicker, the bearing force of whole tire will be stronger, elastic force also can be larger, even if the whole support strength of tire is enough large, if but the outer shroud of tire 4 is because the too hard gravity of polyurethane material is difficult to allow local yielding, this tire will at manned or goods by not producing traveling comfort during rough road surface, and by adjacent two pieces of stay bearing plates and the outer shroud between two pieces of stay bearing plates being arranged to arch configuration 5, thus when allowing the manned or goods of tire cross broken little obstacle, produce the traveling comfort that local yielding acquires a certain degree, one piece tyre support strength is not weakened again simultaneously, comfortable change is but created to whole tire.
The comfortable slow principle of arch configuration 5 is as follows: (1) is when the little obstacle of projection is just in the middle outer shroud tread blocks of the outer shroud that band tire two stay bearing plate correspondence adjacent in opposite directions connects, because this position is just positioned in the middle of the bridge floor of arch bridge, at this moment bear immense pressure can by bridge wall (the outer shroud longitudinal fluting deepened gradually of circular arc at this position, groove cell wall) rapidly squeese pressure is delivered to two in opposite directions and on adjacent stay bearing plate, the outer shroud longitudinal fluting and the groove cell wall that form arch configuration are efficiently compressed when keeping huge bounce simultaneously.(2) when the little obstacle of projection is just in the outer shroud tread blocks of the close stay bearing plate of band tire, because this position is in the thickest position of arch configuration and outer shroud longitudinal fluting innermost, it is also simultaneously the darkest position of outer shroud tread blocks hollow out, therefore higher longer groove cell wall can be extruded rapidly when this part outer shroud tread blocks bears immense pressure, cell wall shortens rapidly and shrinks and power is synchronously delivered on stay bearing plate, because this cell wall is longer compared with other cell walls, therefore larger compression space can be produced and also extraordinary traveling comfort can be produced simultaneously, and structure is not easily destroyed.Therefore, arch configuration 5 not only serves buffer action, protects again stay bearing plate 3 simultaneously and does not act as very first time stress point with the junction of outer shroud 4, thus avoiding tire to cross, bank instantaneous force is excessive that stay bearing plate 3 and outer shroud connecting portion are easily torn or shaken wound.Make polyurethane non-inflatable tyre at harder outer shroud by this structure and need not be complicated stickup rubber tread also can reach the airtyred traveling comfort of rubber like, better make use of simultaneously polyurethane material as tyre surface have wear-resisting, economize can, the high performance of short, the environmental protection of braking distance.
As shown in Figure 3, in order to improve the more superior traveling comfort of non-inflatable tyre, rubber tread 6 can also be wrapped up at the outer shroud 4 of polyurethane non-inflatable tyre, because the hardness of rubber tread 6 own is little compared with polyurethane outer shroud, therefore it has better cushion characteristic, also tire can be made to have better traveling comfort in the process of moving, but its resistance to abrasion is not as polyurethane outer shroud 4, therefore also select whether wrap up rubber tread 6 as required, rubber tread 6 also can replace with the polyurethane of the lower identical type of softness in addition, thus reaches better traveling comfort in tire running process.
