Abstract

An elastically deformable polyform wheel is susceptible of adopting multiple shapes which correspond to efforts derived from various working situations. The wheel is comprised of a central element which includes the rotational axis of said wheel, and intermediate elastically deformable element, connection and rigidification means, and an external tyre. The elastically deformable intermediate element may consist of a continuous, solid and compacted mass, or of individual elements such as appropriately curved, rigid metal sections which extend between the central element and the tyre support, or it may consist of damping elements which are situated radially between said central element and said tyre support, the elements being configured like spokes which are angularly equidistant. The connection and rigidification means may also consist of a steel band and a conformer means of a caterpillar type. This arrangement provides a multideformable wheel which keeps constant its perimetral length.

Antecedentes y Sumario de la InvenciónBackground and Summary of the Invention
Es conocido el hecho de que cualquier vehículo que deba desplazarse sobre algún plano de rodadura, debe incorporar un número de ruedas, variable en función del tipo concreto de vehículo, mediante las que se permite que tal desplazamiento pueda ser llevado a cabo. En general, las ruedas están montadas sobre órganos solidarizados al bastidor del vehículo, normalmente con la colaboración de elementos amortiguadores, solos o combinados con resortes de características apropiadas para cada caso en particular, de modo que cualquier esfuerzo derivado de la utilización del vehículo es suavizado por tales elementos amortiguadores antes de ser finalmente soportado por los citados órganos de vinculación al bastidor. Cuando se trata de vehículos terrestres (o incluso aéreos), cada una de las ruedas montadas en el vehículo incorpora una llanta y una cubierta, de modo que entre la llanta y la cubierta queda un espacio destinado a ser rellenado con un fluido, generalmente aire, de modo que la masa de aire proporcionada se encarga ya de actuar como un primer, y muy importante, elemento amortiguador de los esfuerzos derivados del peso y de la utilización general del vehículo. Aun así, las fuerzas transmitidas a la estructura siguen siendo considerablemente altas, sobre todo cuando se producen situaciones extremas derivadas de frenadas, irregularidades bruscas del plano de rodadura, etc., por lo que sería aconsejable poder disponer de medios que estén capacitados para reducir de forma apropiada la cantidad de esfuerzo transmitido.It is known that any vehicle that should to move on some plane of rolling, it must incorporate a number of wheels, variable depending on the specific type of vehicle, by means of which it is allowed that such displacement can be carried out. In general, the wheels are mounted on bodies in solidarity with the frame of the vehicle, usually with the collaboration of shock absorbers, alone or in combination with springs of appropriate characteristics for each particular case, so that any effort derived from the use of the vehicle is smoothed by such damping elements before being finally supported by the aforementioned linkage bodies to the frame. When it comes to land vehicles (or even air vehicles), each of the wheels mounted on the vehicle incorporates a tire and a cover, so that between the tire and the cover is a space intended to be filled with a fluid, usually air , so that the mass of air provided is already responsible for acting as a first, and very important, damping element of the efforts derived from the weight and the general use of the vehicle. Even so, the forces transmitted to the structure remain considerably high, especially when extreme situations arise due to braking, sudden irregularities of the tread, etc., so it would be advisable to have means that are capable of reducing appropriate form the amount of effort transmitted.
Este objetivo se ha alcanzado mediante la rueda poliforme propuesta por la presente invención, la cual proporciona ya en sí misma un medio ventajoso de absorción de esfuerzos en virtud de la configuración y de las características constructivas de que se ha dotado a la misma. La rueda de la invención se caracteriza esencialmente por su capacidad de deformación elástica, resultando aplicable a cualquier tipo de vehículo, ya sea de tipo doméstico (bicicletas, motos, automóviles), como a cualquier vehículo de tipo comercial, industrial, etc.This objective has been achieved by means of the polyform wheel proposed by the present invention, which already provides in itself an advantageous means of absorbing stresses by virtue of the configuration and the constructive characteristics that it has been endowed with. The wheel of the invention is essentially characterized by its elastic deformation capacity, being applicable to any type of vehicle, whether of a domestic type (bicycles, motorcycles, automobiles), as well as any commercial, industrial type vehicle, etc.
La capacidad de deformación elástica, y por tanto de absorción de esfuerzos, de la rueda que va a ser objeto de descripción, se deriva de sus características constructivas, al estar concebida de forma que, cualquiera que sea la forma adoptada por la rueda, se mantiene constante la dimensión longitudinal de su circunferencia. La capacidad de deformación elástica de la rueda viene proporcionada por los componentes internos que incorpora, y que pueden corresponder, según diferentes alternativas de realización, con una masa elástica deformable, extendida entre un elemento central de fijación al eje de giro y que está constituido a modo de silentbloc o similar, y el elemento de soporte del neumático exterior; también se puede llevar a cabo la vinculación entre el elemento central y el soporte del neumático con la utilización de una pluralidad de amortiguadores individuales, dispuestos a modo de radios, con la colaboración de resortes colocados por el exterior o incluso en el interior de dichos elementos amortiguadores individuales radiales, o incluso con otros elementos rígidos curvados apropiadamente para conseguir la flexión elástica deseada.The capacity of elastic deformation, and therefore of stress absorption, of the wheel to be described, is derived from its constructive characteristics, as it is designed so that, whatever the shape adopted by the wheel, it is keeps the longitudinal dimension of its circumference constant. The capacity of elastic deformation of the wheel is provided by the internal components that it incorporates, and which may correspond, according to different embodiments, with a deformable elastic mass, extended between a central element for fixing to the axis of rotation and which is constituted to silentbloc mode or similar, and the outer tire support element; The connection between the central element and the tire support can also be carried out with the use of a plurality of individual shock absorbers, arranged as spokes, with the collaboration of springs placed outside or even inside said elements. individual radial dampers, or even with other rigid elements properly curved to achieve the desired elastic flexion.

Descripción de las Realizaciones Preferidas Según se ha indicado en lo que antecede, las Figuras de los dibujos anexos representan diversas opciones preferentes de realización del objeto de la invención, a través de las cuales puede entenderse la forma en que funciona la rueda en su montaje en un vehículo cualquiera.DESCRIPTION OF THE PREFERRED EMBODIMENTS As indicated above, the Figures in the accompanying drawings represent various preferred options for carrying out the object of the invention, through which the manner in which the wheel works in its assembly in any vehicle.
Haciendo referencia, en primer lugar, a la Figura 1 , a través de las distintas vistas representadas en la misma, se puede apreciar una forma de realización en la que la rueda de la invención está constituida, de manera simplificada, por un elemento central (1) constitutivo del elemento de vinculación al bastidor del vehículo para la provisión del eje de rotación de la rueda, y rodeando a dicho eje (1), una masa (2) elásticamente deformable, constitutiva del medio de unión y soporte a un neumático (3) exterior convencional. Las consecuencias que se pueden desprender de estas representaciones explican perfectamente el funcionamiento de una rueda construida de acuerdo con la invención. En efecto, la acción de absorción de los esfuerzos derivados de las distintas situaciones a las que se ve sometida dicha rueda, son absorbidas por el conjunto constituido por el propio neumático externo (3) y por la masa (2) macizada dispuesta alrededor del eje (1). Un ejemplo de situación normal de esfuerzo suplementario, aparece en una de las vistas de dicha Figura, en la que una irregularidad (4) del plano de rodadura provoca la deformación parcial del conjunto neumático- masa deformable, haciendo que este conjunto ceda radialmente hacia el interior. También merece un comentario especial la situación derivada de una frenada brusca en la que se origina un esfuerzo horizontal considerable en virtud de la inercia del vehículo derivada del movimiento a que esté sometido en ese momento, y que junto con el conocido efecto de "cabeceo" del vehículo, da lugar a una fuerza resultante que provocará la deformación elástica en la dirección correspondiente, quedando así absorbido el esfuerzo y aumentando proporcionalmente la superficie de contacto con el firme para mayor agarre a éste, y recuperando el conjunto la forma habitual una vez que tales fuerzas dejan de actuar.Referring, first, to Figure 1, through the different views represented therein, an embodiment can be seen in which the wheel of the invention is constituted, in a simplified manner, by a central element ( 1) constituting the linkage element to the frame of the vehicle for the provision of the axis of rotation of the wheel, and surrounding said axle (1), an elastically deformable mass (2), constituting the means of attachment and support to a tire ( 3) conventional exterior. The consequences that can be derived from these representations perfectly explain the operation of a wheel constructed in accordance with the invention. In fact, the action of absorption of the stresses derived from the different situations to which said wheel is subjected, are absorbed by the assembly constituted by the external tire itself (3) and by the solid mass (2) arranged around the axle (one). An example of a normal situation of supplementary stress appears in one of the views of said Figure, in which an irregularity (4) of the tread causes partial deformation of the deformable pneumatic mass assembly, causing this assembly to yield radially towards the inside. The situation derived from sudden braking in which a considerable horizontal effort originates due to the inertia of the vehicle derived from the movement to which it is subjected at that time, and which together with the known "pitching" effect, also deserves special comment. of the vehicle, gives rise to a resulting force that will cause the elastic deformation in the corresponding direction, the effort being thus absorbed and proportionally increasing the contact surface with the firm for greater grip on it, and recovering the assembly in the usual way once that such forces stop acting.
De igual manera, se debe apreciar este mismo efecto de absorción de esfuerzos y aumento del agarre en tarea de empuje en el caso de vehículos tractores o remolcadores.In the same way, this same effect of absorption of efforts and increase of the grip in the task of thrust in the case of tractor or tug vehicles must be appreciated.
Una realización particularmente preferida es la que aparece representada a través de las diferentes vistas de la Figura 2, las cuales se corresponden respectivamente con las vistas de la Figura 1 anterior. Como elementos coincidentes con la realización anterior, estas representaciones muestran una rueda poliforme formada a partir de un eje central (1) con respecto al cual puede girar la misma, y un neumático (3) exterior convencional, de modo que en este caso se ha sustituido la masa intermedia por una multiplicidad de elementos amortiguadores (5) individuales, dispuestos radialmente y extendidos entre un soporte (6) del neumático, al que se unen por uno de sus extremos, y el citado eje (1) al que unen por el extremo opuesto. Como se ha dicho, la disposición de tales elementos (5) amortiguadores es radial, y están equiespaciados angularmente. Al igual que en el caso de la Figura 1, una irregularidad (4) presente en el plano de rodadura provocará la actuación de los elementos (5) amortiguadores correspondientes según un movimiento de retracción hacia el centro. La recuperación de los mismos, una vez que se ha superado la posición de tal irregularidad, devuelve el conjunto a su forma original.A particularly preferred embodiment is that shown through the different views of Figure 2, which correspond respectively to the views of Figure 1 above. As elements coinciding with the previous embodiment, these representations show a polyform wheel formed from a central axis (1) with respect to which it can rotate, and a conventional exterior tire (3), so that in this case it has been replaced the intermediate mass by a multiplicity of individual damping elements (5), arranged radially and extended between a support (6) of the tire, to which they are joined by one of its ends, and the aforementioned axis (1) to which they join by the opposite end. As said, the arrangement of such damping elements (5) is radial, and they are angularly spaced. As in the case of Figure 1, an irregularity (4) present in the tread will cause the corresponding damping elements (5) to act according to a retraction movement towards the center. The recovery of the same, once the position of such irregularity has been overcome, returns the assembly to its original form.
Como particularización de esta última realización comentada, la invención ha previsto que los elementos (5) amortiguadores puedan ser de cualquier tipo con el fin de que constituyan radios efectivos capaces de adaptarse a las distintas situaciones, pudiendo consistir en amortiguadores convencionales rellenos con fluido hidráulico, o incluso ser actuables por comando desde un lugar remoto, por ejemplo desde una posición predeterminada del tablero del vehículo, o incorporado en el sistema de conducción.As a particularization of this last commented embodiment, the invention has provided that the damping elements (5) can be of any type in order to constitute effective radii capable of adapt to different situations, which may consist of conventional shock absorbers filled with hydraulic fluid, or even be operated by command from a remote location, for example from a predetermined position of the vehicle dashboard, or incorporated into the driving system.
La representación de la Figura 3 es igualmente correspondiente con las dos anteriores comentadas, pero en este caso se han sustituido los elementos amortiguadores intermedios por otros elementos resistentes rígidizados, constituidos por tramos (7) metálicos de sección transversal rectangular invariable, cuyos lados mayores se extienden en planos paralelos al eje de la rueda para impedir la flexión de dichos tramos en sentido lateral con respecto a la rueda, extendidos en planos equivalentes entre el eje (1) central y el soporte (6) del neumático (3). La curvatura proporcionada a tales elementos (7) provoca la flexión de los mismos en correspondencia con el esfuerzo que se ejerza sobre la rueda, absorbiendo así, junto con el propio neumático (3), tales esfuerzos. También en este caso aparece una posición en la que se ha representado la rueda de la invención situada sobre una irregularidad (4) del plano de rodadura.The representation of Figure 3 is also corresponding to the two previous ones mentioned, but in this case the intermediate damping elements have been replaced by other rigid stiffened elements, constituted by metal sections (7) of invariable rectangular cross-section, whose major sides extend in planes parallel to the axis of the wheel to prevent bending of said sections laterally with respect to the wheel, extended in equivalent planes between the central axle (1) and the support (6) of the tire (3). The curvature provided to such elements (7) causes them to flex in correspondence with the effort exerted on the wheel, thus absorbing, together with the tire itself (3), such forces. In this case too, a position appears in which the wheel of the invention is shown on an irregularity (4) of the tread.
La Figura 4 muestra, por último, una materialización práctica detallada de una rueda según la invención, correspondiente en particular con la realización de la Figura 2, en la que se utilizan amortiguadores (5), dispuestos radialmente, equiespaciados angularmente, como medios de vinculación entre una pieza (8) interna, constituida a modo de silentbloc, de mayor diámetro que el eje simple, y que incluye además el eje de giro de la rueda, y el elemento (6) de soporte del neumático (3) externo. Cada uno de los amortiguadores (5) puede estar dispuesto en el interior de un resorte (9) respectivo, constituido a modo de doble espiral, y por la parte externa del soporte (6) se ha dispuesto un medio conformador constituido a modo de oruga por una pluralidad de eslabones (10) articulados sucesivamente entre sí. El elemento (6) de soporte del neumático está constituido por una banda de acero que da consistencia a la estructura circunferencial interradial de la rueda, evitando una deformación incontrolada de tal estructura circunferencial debido a su carácter articulado a modo de oruga. El citado medio conformador y el elemento de soporte están capacitados para mantener constante la longitud perimetral del conjunto, de modo que las fuerzas derivadas de la actuación de la rueda y aplicadas perimetralmente a la misma, provocan la actuación de los amortiguadores (5) hasta la compensación del esfuerzo, junto con la deformación del propio neumático (3), y de modo que los resortes (9) no sólo colaboran en el efecto amortiguador sino que además, junto con el elemento de soporte, proporcionan la fuerza de recuperación necesaria para devolver a la rueda la forma original cuando cesan los esfuerzos sobre la misma.Figure 4 shows, finally, a detailed practical embodiment of a wheel according to the invention, corresponding in particular with the embodiment of Figure 2, in which radially arranged dampers (5) are used, angularly spaced apart, as linking means between an internal part (8), constituted as a silent block, of a larger diameter than the single axle, and which also includes the axis of rotation of the wheel, and the support element (6) of the external tire (3). Each one of The dampers (5) can be arranged inside a respective spring (9), constituted as a double spiral, and a forming means constituted by a plurality of a plurality is provided by the external part of the support (6). of links (10) articulated successively with each other. The support element (6) of the tire is constituted by a steel band that gives consistency to the interradial circumferential structure of the wheel, avoiding uncontrolled deformation of such circumferential structure due to its articulated caterpillar-like character. The said shaping means and the support element are capable of maintaining the perimeter length of the assembly constant, so that the forces derived from the operation of the wheel and applied perimeter to it, cause the action of the dampers (5) until compensation of the effort, together with the deformation of the tire itself (3), and so that the springs (9) not only collaborate in the damping effect but also, together with the support element, provide the necessary recovery force to return to the wheel the original form when the efforts on it cease.
Asimismo, el resorte (9) anteriormente descrito puede alojarse en el interior de cada uno de los amortiguadores (5), siendo esta configuración operativamente equivalente a la anteriormente descrita.Likewise, the spring (9) described above can be housed inside each of the dampers (5), this configuration being operationally equivalent to the one described above.
La razón de constituir el centro de la rueda a modo de silentblock radica en que, al producirse una deformación del perímetro de la rueda, las distancias angulares entre radios varían, por lo que, de no estar éstos unidos de manera elástica o articulada al soporte central, se producirían esfuerzos que llevarían a la fractura de los materiales en las uniones de los radios con el soporte central de los mismos.The reason for constituting the center of the wheel as a silentblock is that, when deformation of the perimeter of the wheel occurs, the angular distances between spokes vary, therefore, if they are not elastically attached or articulated to the support central, there would be efforts that would lead to the fracture of the materials at the junctions of the spokes with the central support of them.
Por igual motivo, y tal como se detalla en la figura 4, los radios quedan unidos al elemento (6) de soporte mediante articulaciones conocidas por medio de pernos o pasadores (11).For the same reason, and as detailed in Figure 4, the spokes are attached to the support element (6) by means of known joints by means of bolts or pins (11).
Como se comprenderá, la provisión de ruedas como las comentadas a un vehículo normal supone una considerable simplificación del conjunto, además de una seguridad incrementada, con el consiguiente ahorro económico que todo ello supone. As will be understood, the provision of wheels such as those commented to a normal vehicle implies a considerable simplification of the set, in addition to an increased safety, with the consequent economic savings that all this entails.
