Abstract
The present invention discloses a wheel with large bending rigidity and less rolling resistance. It is a solid wheel with high-modulus skeleton or an inflated wheel with large-bending rigidity skeleton inside its inner tube.
Description
The present invention relates to the vehicle wheel.
Usually wheel comprises wheel rim and tire, and tire divides band tyre and air-inflation tyre.Air-inflation tyre comprises the inflatable inner tube and the cover tire of pressure-bearing, and cover tire comprises tyre surface, carcass and tyre bead.The analogy air-inflation tyre partly is the elastic body inner tube of a tyre with solid tyre center pressure-bearing, and solid tyre also comprises tyre surface, tyre bead and carcass (low modulus).Because of the tension force carrying that the main inner pressure of carcass causes, rolling resistance is big.
The invention provides carcass also with the wheel of other internal force carryings, reduce resistance.
The present invention seeks to realize like this, carcass comprises the high-modulus casing play, casing play itself or with big plain bending rigidity D is arranged after miscellaneous part combine, make the increase of carcass moment of flexure carrying share, the reduction resistance.Can add deep tread when causing ground plane to reduce and/or use gripping pattern.
Solid carcass comprises the skeleton 4 of high-modulus and/or than the skeleton 4 ' of macrobending rigidity.
The inflation carcass comprises the skeleton 4 ' than macrobending rigidity.
The above-mentioned parts that are provided with the solid of skeleton 4 and/or skeleton 4 ' or air-inflation tyre wheel become the interrelated product that can not separately use.
Moment of flexure carrying share is big, and the tension force share is just little, and interior drops reduces raw materials consumption.
Concrete structure of the present invention is provided by following examples and accompanying drawing.
Fig. 1, wheel.Fig. 2, embodiment 1.Fig. 3, embodiment 2.Fig. 4, embodiment 3.Fig. 5, embodiment 4.Fig. 6, embodiment 5.Fig. 7, example 5 elastic body inner tube of a tyre circumferentially deployings.Fig. 8, resistance decline principle.Fig. 9, distortion is decomposed.
Fig. 1, wheel comprise the wheel rim 2 that connects axletree hole 1, and the inner tube of a tyre 3 comprises skeleton 4,4 ' carcass, tyre surface 5, tyre bead 6.Skeleton 4 is carcass pliess, extends and connection tyre bead 6 from crown.Skeleton 4 ' has big plane 7 bending stiffnesses, and as thin-walled steel loop or plastic hoop, inner edge separates with wheel rim, does not influence crooked radial displacement.Outer rim is covered pressure by skeleton 4 and/or tyre surface 5.On 7 sections of plane from inside to outside ordering be wheel rim, the inner tube of a tyre, carcass, tyre surface.Fig. 2-the 6th, embodiment omit the cross-sectional figure of hatching.Fig. 2, skeleton 4 ' linear pattern, during inflatable inner tube, skeleton 4 ' is positioned at skeleton 4 outside banding skeletons 4, the best meridian direction of skeleton 4 cords; During elastic body (as rubber, the polyurethane etc.) inner tube of a tyre, skeleton 4 ' is in skeleton 4 inboards, and preferably the banding inner tube of a tyre has the elastic body inner tube of a tyre and radially gives pressure (also being interior pressure), and the sidepiece 10 of skeleton 4 is preferably straight.These structural constraints of (inflation and elastic body) tire the crooked radial displacement of carcass, improved bending stiffness.Fig. 8 reduces the resistance principle.Drive torque M is that zero hour wheel subcenter Q is subjected to gravity P, wheel rim 2 distance h that descended, and the outer rim of matrix crown 12 and tyre surface 5 has gravity deformation 17, shown in solid line.It is 11,11 ' that tyre surface 5 has left and right end points, keeps in touch ground-surface 14 before critical conditions.Point 11 and 11 ' is located tyre surface and be squeezed into evagination flange 13,13 ' under following two factors: 1, face 14 place's tyre surfaces are compressed by ground reaction force (P that makes a concerted effort crosses the Q point); 2,11,11 ' locate bizet 12 curvature and diminish.Ground connection tyre surface 5 ', the carcass and the inner tube of a tyre are the tire base together with the tyre surface at bizet 12 outsides, face 14 places, and it is 16,16 ' interface 12 ' that tyre surface 5 ' and tire base have end points.The carcass of common solid tyre and the elastic body inner tube of a tyre all are the low amount of touching materials, and flange 13 is that the bending that the tire base diminishes in point 11 place's curvature makes bizet 12 pressurizeds subdue evagination formation, and tire base cross-sectional plane is subdued part and do not born moment of flexure.The skeleton 4 of the high amount of touching (tightening force is arranged) has retrained subdues evagination and makes the cross section hold curved ability to increase.Make M increase to rolling resistance moment M ' and promptly put 11 maximum torques of built on stilts not, reach the dotted line position of critical conditions.Wheel rim 2 turns over an angle θ moves to right apart from d the Q point, at point 11 places, the strain reversing sense that strain that moment M ' produces and gravity produce is cancelled each other, flange 13 disappears, bizet 12 curvature are recovered, and it is equidirectional with the gravity strain to locate the moment strain at point 11 ' on the contrary, superposes mutually, flange 13 ' is enlarged, the curvature of bizet 12 more reduces, and causes ground connection place bizet 12 to have a down dip to the right, and tyre surface 5 bulk compressibilitys below it are left small and right large.Stack up ground reaction force P point of action moves to right apart from d+S, i.e. M '=PS.Because being the wheel rim rotation and the extruding tire that moves to right, causes S, so S increases with θ.If M '=N+N ', N and N ' are the resisting moments on face that respectively acts on 14 and the additional facet 14 '.Fig. 9 is decomposed into distortion A with critical strain: locate effect-N at distortion 17 interface 12 ', and distortion B: respectively act on M ', N at the Q point, the interface 12 ' that are out of shape A; Sum.Distortion B is equal to remake with an interface 12 ' of only preventing the bearing 15 fixed deformation A that rotate and uses M '.Distortion A mainly makes tyre surface 5 ' distortion, and distortion B mainly makes the flexural deformation of tire base produce additional facet 14 '.Obviously carcass bending stiffness D increases, and N reduces, and distortion B reduces, and N ' reduces, and M ' reduces.If D=∞, distortion B=0, M '=N=makes the rolling resistance moment X of common solid tyre with tyre surface 5, and is minimum, less relatively because of the 12 ' bending of critical conditions interface, makes D less to the N influence, generally approximately thinks that N=X and D have nothing to do.If increasing and reduce interior pressure simultaneously, D can realize that resistance and radial elastic all reduce.
Fig. 3 does not have skeleton 4 ', and almost entirely by the tension force carrying, interior pressure is bigger.It during inflatable inner tube the tire of common no bracing ply; Skeleton 4 can not extend to tyre bead 6 but linear pattern (referring to Fig. 6) during the elastic body inner tube of a tyre.Fig. 4, skeleton 4 ' the stretching elastic body inner tube of a tyre 3, almost entirely by the moment of flexure carrying, add the shear deformation of circumferential distribution uniform, can exoskeletal 4, the elastic body inner tube of a tyre 3, tyre bead 6 and tyre surface 5 link to each other, and at this moment tyre surface sidepiece 8 can have less radial elastic (as flexure type) with the excessive bending stiffness of balance skeleton 4 '.Fig. 3, the 4th, two extreme special cases of Fig. 2, moment of flexure and tension force all be can not ignore in Fig. 2 carcass, look particular case skeleton 4 can be wanted or not, link to each other with tyre surface as tyre bead 6 in exoskeletal 4 o'clock, can make straight with tyre surface sidepiece (replacement skeleton 4 sidepieces).Fig. 6, because of no side pressure, tyre bead 6 can move on on the inner tube of a tyre 3 during the elastic body inner tube of a tyre, and the inner tube of a tyre 3 can have horizontal reinforced rib 9 (Fig. 7).Fig. 5, the inner tube of a tyre 3 can connect tyre surface 5 during the elastic body inner tube of a tyre.At Fig. 4, also can keep the skeleton 4 (Fig. 2) that connects tyre bead in 5.The tyre bead 6 that links to each other with skeleton 4 (as Fig. 4,5 or 6) can not contain bead coil or ebonite core.Skeleton 4 ' can be sticking or identical with adjacent cover tire parts.Fig. 6 also can tyre surface 5 and skeleton 4 ' all be iron or nylon, high-modulus, and tyre surface 5 and skeleton 4 ' link together, as the wheel of handcar, furniture, case and bag.Name the parts that comprise them with the structure that links to each other, these parts comprise: Fig. 2, and wheel rim 2, skeleton 4 ', the elastic body inner tube of a tyre 3, tyre bead 6, skeleton 4 are connected with tyre surface 5; Fig. 4, the elastic body inner tube of a tyre 3, tyre bead 6 are connected with tyre surface 5; Fig. 5, the elastic body inner tube of a tyre 3, tyre bead 6 are connected with tyre surface 5, and the elastic body inner tube of a tyre 3, tyre bead 6, skeleton 4 are connected with tyre surface 5; Fig. 6, tyre bead 6 is connected with the elastic body inner tube of a tyre 3, tyre surface 5.
