The present invention consists in a system to subject flexible wheels or radially articulable which, in a complβte- y autogenous way, offer t ea a smooth rolling, but with ex¬ treme firaneββ, with almost complete abβortion of impacts and trepidation.
The main advantage of the system, here also denominated axial oscillating subject©re, which can be used to equip any kind of rotating or flyng vehicles, is that, comparing with conventional wheels that oan diminish impacts and trepidation only by the utilisation of no much efficient mechanical im¬ pact abβorverβ, hydraulics or pneumatics, when the present in ventlon utilise only its own constitution and way of functio- ning, sufficiently and automatically, to avoid effects of reaction, resiliency and elastic return to wlch the wheels are submitted when used in irregular tracks.
Another innovation who introduce is the possibility of utilisation of simple flexible or articulable treds, without necessity of circular rigid support for him set, or uβe tireβ subject to punctures or leackageβ, for example, because with the system now presented the flexible wheels will only re¬ tract in the small areas receiving impacts or that are in con tact with the surface, eopyng the irregularities, while the others areas will stay firmly in tension, with enough circu¬ lar rigidity to support charges gradually greater or stokes without losing alignment.
Pratically, it consist of a pair of axles or rolling bearings in disc shape that can oscillate or incline their rolling angles one towards the other, allwayβ in simultaneous opposite movements in relation to the plan of flexible wheels to which are radially linked and in obliquity be both sides, in a way to keep them firmly in tension and, so, can roll pro ducing the movements that generate the absorving physical effects that characterize this invention an is functioning.
Its was specially produced to equip small vehicles,
wlth the simultaneous function of wheel and impact absorver, like bicycles, but can be freely used in any other vehicle and without restrictions to the uβe of accessories such as traction systems, guiding, as well as the adoption of other implements which can be incorpored or not, that aim adequate it to different uses and aplications.
The illuβtrativeβ drawings enclose are βeai-βcheaatlc and only βhowβ the ideal configuration of the axial oscilla¬ ting subjectorβ, because there are others configurations that can be adopted to produce the same rolling and oβcillating mo vementβ, in opposition, when subjecting flexible wheels as re lated and claimed from now on.
These drawings will also show the axial oscillating sub jectorβ subjecting optional flexible wheels, not restrict! es, only to show the well characterized movements of both, a ba¬ sic factor of functioning of this invention.
The drawing 1, figure 1, show the axial oβcillating sub jectors with its own configuration and disposition, with sec¬ tions cuts. The drawing 2, figure 2, show same subjectore, without the sections showed in the drawing 1, figure 1, subjecting a optional flexible wheel only as example.
The drawing 3, figure 3 * show a diametral and frontal cut of these βubjectors without the incidence of any forces or charges on them, to better show them in these conditions and to exemplify their functioning with the following draw¬ ings and indications *
The drawing 4, figure 4, show the same section of the su ectors showed in drawing 3, figure 3 » but with incidence of forces or charges on theirs axles, represented by vertical arrows in the imaginary forks.
The drawing 5, figure 5, show a lateral wiew of the βubjectors, almost the drawing 4, figure 4, but where was added a detail, indicated in the dashed circle, of an irregu- larity of the surface that make retract the small area in the inferior part of the flexible wheel, in contact with it, co-
pyng its shape, main advantage of this invention.
In drawings 3, 4 and 5, it was added a figure of a fork similar to those used in bicycles, be means of imaginary li¬ nes of trace and point, only to show a kind of optional βub- jection or fixation that the axial oscillating subjection can freely adopt.
The drawing 1, figure 1, show the ideal composition of the axial oscillating βubjectors (5), that are oscillating axles (1) couplet by spheres joint (2) to other fixing axles (3) that, in relation to the last ones, can oscillate in pen dulum movement or freely describe trajectory of imaginary co¬ nes, both in articulation movements.
This set of axles so couplet will form pairs in rectil.1 near disposition in a way they can execute oβcillating move- mβnts in opposition, simultaneously, as if they were perfor¬ med in front a mirror, for example.
To assure the simultaneous movements also to reduce the attrition in the bearings, the central and internal points of contact, side to side, of the axial oscillating βubjectors (5) can be optionally made of hemispherical surfaces, such aβ, for example, the two semi-spheres (8), that form a single sphere, wrapped up the ring (9).
Around the oβcillating axles (1), with the possibility of utilisation of systems to reduce the friction such aβ ball bearings (4), will rotate the axial oscillating βubjectorβ (5), wioh, βo, will acquire the same variable movements of oscillation executed by the first ones, basics and characte¬ ristics of this invention.
In drawing 2, figure 2, the axial oβcillating tors (5) get together by flexible linklns (6) to the optio-/ nals wheels (7), also flexibleβ or radially artloulablββ, co posing a rotating complete set, will the purpose of wheel to any vehicle, almost shock, impacts and trepidation proof.
The flexible wheels (7) or tredβ will allwayβ be optio- nals, since they are useful for an ideal functioning, there¬ fore what is claimed here is the way how they are subjected
by the axial oscillating subjβc ore (5). in radial obliquity through of linkingβ (6), and the intrinβic movements that execute in accordance those characteristics.
The type of construction of the axial oβcillating βub- jectorβ (5) aβ showed in the drawings, similar to the arming of wires of bicycle wheels, represent only their ideal con¬ formation, βince they can adopt any other shapes sizes or totating systems.
The two baβlo working characteristics of this invβn- tion, the first one, that is provide a circular rigity in flexible wheels (7) able to support the charges to be trans¬ ported and, the βecond one, to absorb the impacts without deformation or losing the its alignement, are obtained βiaul tanβouβlly and automatically, by the fact of being joined to the axial oscillating subjectorβ (5) in radial oblique sense to both sides and so being in tensity by lateral swinging movements, oscillatory or inclination in opposition, natura¬ lly produoed by them as they are put in rolling movement with charges. This is demonstrated with drawings 3 and 4, where two/ diametral sections of the axial oscillating subjeotorβ (5), corretly assembled on the oscillating axle (1) and fixing/ axles (3) ? as weel as subjecting, by linkingβ (6), optional flexible wheels (7). The drawing, 3, figure 3, shews this set assembled wi¬ th the characteristics of this invention, in balance of ten¬ sions because there are no incidenβe of charges or impacts over them.
The drawing 4, figure 4, otherwise, shows them supo£ ting charges and impacts, indicating phases of functioning, with the resultant inclination of the subjeotorβ (5), which is the practical way as it absorbs, in direct proportion to the intensity, of its potential energy.
Under the effect of these charges or impacts, re resen ted by the vertical arrows in drawing 4, figure 4, there will be a natural, gradual or sudden depending on the case.
inclination in opposition of the axial oscillating sub ec¬ tors (5) in relation to the rolling plan of the flexible subjected wheel (7), bringing their own rolling angles near in the superior region and, consequently, separating in the inferior region, wich will induce in the linkings (6) a constant radial and uniform stretching in all areas of the flexible wheels (7), even for those placed below the axle 11 nes, what would not happen in case there where on oblique ra dial forces of stretching in perfect uniformity, produced by this invention with such characteristics movements.
This uniform radial oblique stretching represents the own functioning of this invention, in what concerns the main tenance of the flexible wheel (7) with the circular rigity necessary to support great charges and the capacity of absor bing impacts and trepidation, because it is expontaneously generated and in completely autogenous way by its own consti_ tution and way of natural working.
In drawing 4, figure 4, indicated by the bold arrows, plaoed near the areas where that axial oscillating subjβc- tore (5) are joined to the linkings (6), it is demonstrated that the swinging movements in oscillating or inclination executed, can absorb or assure that is will rebound the βnβjr gy produced by the bumps in the flexible wheels (7) only in axial direction, without inducing elastic return or any other physical reaction in opposition to its absortion and elimination.
Another factor of absortion of impacts generated by the uniform radial oblique stretching is the one showed in dra¬ wing 5, figure 5, where it can be noticed that, although the wheel (7) in completely flexible or radially articulable, it stays fixed by at least two points inset, by the rigid clips (10), what assures an extraordinary circular rigity, because it is impossible that these and the linkingβ (6) to witch are tied suffer any desviation in the oblique radial sense, as showed by the more vertical arrows in the dashed circle. Whit this working system, that prevent the loosening
of the linkings (6) placed in the inferior region of the flexible wheels, these will never loose their circular rigi¬ ty, since they constructed with adequatβd materials, in ex¬ ception of the small areas receiving preββure or impacts of the surface, that will to yield, absorbing them, by the effect of flacoidity of the linkingβ (6) as indioated by the horizontal arrows in the same dashed cirole of drawing 5, fi. gure 5 *
The axial oscillating βubjβctorβ (5) can also adopt a meeting system, or mutual back seat, in its rolling oenter, that preferentially rotate with them, composed by two semi- spheres (6) that, beside making contact by means of spheri¬ cal surfaces, wich points of generation are the same points of articulation of the axles (1) form also an sphere artiou- lation surrounded by the ring (9) in order to realize the oscillatory movements in oppoaitlon that characterize this/ invention, without changing the distβnoe between the axles and, also, nullifyng the binary oblique forces of attraction aplied in the linkingβ (6). For this purpose other systems can be freely adopted, such as equiping the semi-spheres (8) with gear teeth deβcrl. bing oircleβ, for example, or simply using oscillating bea¬ rings of axial seat.
By the fact this invention had been produced using con cepts settled by the practice, all its component•..should fo¬ llow rigid constructive rules, concerning the resiβtenoy of the materials and its geometry, proportions and properties/ that aids its purpose as absorbing iapaets and trepidation, also the optional flexible wheels used in complement βhould have all the requisites that provide, to set forming, all the ideal conditions of functioning.
