PLATOS EXCÉNTRICOSEccentric Dishes
La presente invención consiste en un sistema de eje de pedales (pedalier) especial para bicicletas y máquinas de tracción humana por pedales, que permite independizar las bielas sincronizándolas con una relación de transmisión variable de forma senoidal, de forma que para conseguir la tracción requiere el uso de platos excéntricos o descentrados según las invenciones reivindicadas en las solicitudes de patente españolas P9501429 del 17 de Julio de 1995 y P9601579 del 15 de Julio de 1996, ambas incluidas en la patente U.S.A. n° 5,899,477 concedida al solicitante de la presente el 4 de Mayo de 1999. Ambas invenciones también corresponden al inventor de la presente. Asimismo, la solicitud P9601579 ha sido objeto de extensión internacional PCT con número de publicación WO 98/02344.The present invention consists of a system of pedal axles (bottom bracket) for bicycles and human traction machines for pedals, which allows the cranks to be independent by synchronizing them with a sine-shaped variable transmission ratio, so that to achieve traction requires the use of eccentric or offset plates according to the inventions claimed in Spanish patent applications P9501429 of July 17, 1995 and P9601579 of July 15, 1996, both included in US Pat.

Also, the application P9601579 has been the subject of PCT international extension with publication number WO 98/02344.
Las dos solicitudes señaladas se refieren a diferentes sistemas de tracción para bicicletas: los mecanismos de ambas invenciones hacen uso de cuatro engranajes elípticos que engranan dos a dos para conseguir la relación de transmisión deseada entre los pedales, y de platos excéntricos siendo siempre la excentricidad de los platos función de la de los engranajes. Ambas patentes se resumen como sigue:The two applications referred to refer to different traction systems for bicycles: the mechanisms of both inventions make use of four elliptical gears that engage two to two to achieve the desired transmission ratio between the pedals, and eccentric plates always being the eccentricity of The dishes function of the gears. Both patents are summarized as follows:
- La solicitud P9501429 reivindica un sistema de tracción que utiliza dos cadenas y dos juegos de platos excéntricos que corresponden a cada uno de los pedales, sincronizados por los cuatro engranajes elípticos, yendo las dos bielas, dos de los engranajes elípticos y los dos platos montados en un primer eje en el pedalier; mientras que los otros dos engranajes que engranan con los anteriores consiguiendo la sincronización entre los pedales, van montados en un segundo eje. La tracción a la rueda desde cada una de las bielas se realiza directamente por cadena mediante un plato excéntrico, mientras la misión de los engranajes es únicamente sincronizar las bielas, y por tanto los pedales, con una relación de transmisión variable de forma senoidal. - La solicitud P9601579 usa una única cadena y un juego de platos excéntricos ligado a una de las bielas, y el mecanismo incluye dos parejas de engranajes elípticos: una de las parejas de engranajes, con cada uno de estos ligado a cada una de las bielas, va montada sobre el eje principal, en el pedalier, y la otra pareja, cuyos engranajes engranan con los anteriores consiguiendo la sincronización entre los pedales, va montada en un eje secundario. La tracción desde una de las bielas se realiza directamente por cadena desde un plato excéntrico, mientras que la biela opuesta se ve afectada por la transmisión, a través de los engranajes, hacia la otra biela.- Application P9501429 claims a traction system that uses two chains and two sets of eccentric plates corresponding to each of the pedals, synchronized by the four elliptical gears, the two connecting rods, two of the elliptical gears and the two mounted plates on a first axle on the bottom bracket; while the other two gears that mesh with the previous ones, achieving synchronization between the pedals, are mounted on a second axle. The wheel drive from each of the cranks is carried out directly by chain using an eccentric plate, while the mission of the gears is only to synchronize the cranks, and therefore the pedals, with a variable transmission ratio of sinusoidal shape. - Application P9601579 uses a single chain and an eccentric plate set linked to one of the connecting rods, and the mechanism includes two pairs of elliptical gears: one of the gear pairs, with each of these linked to each of the connecting rods. , it is mounted on the main axle, on the bottom bracket, and the other pair, whose gears mesh with the previous ones, achieving synchronization between the pedals, is mounted on a secondary axis. Traction from one of the connecting rods is carried out directly by chain from an eccentric plate, while the opposite connecting rod is affected by the transmission, through the gears, towards the other connecting rod.
El nuevo pedalier que se reivindica en la presente solicitud y que se describe a continuación permite indistintamente el uso de dos cadenas y conjuntos de platos excéntricos, según el sistema mecánico correspondiente a la solicitud P9501429, y el uso de una sola cadena y conjunto de platos excéntricos asociado a una de las bielas, según el sistema mecánico correspondiente a la solicitud P9601579.The new bottom bracket that is claimed in the present application and described below allows both the use of two chains and eccentric plate assemblies, according to the mechanical system corresponding to the application P9501429, and the use of a single chain and set of plates eccentrics associated with one of the connecting rods, according to the mechanical system corresponding to the application P9601579.
Este nuevo pedalier comprende: dos semiejes (1 , 1') que conforman el eje de pedales; un eje secundario (2); cuatro engranajes elípticos (3, 4, 5, 6); elementos de rodadura (8) y otros que sean requeridos para el ensamblaje; y, como elemento estructural y protector de los mecanismos anteriores, un subchasis (7).This new bottom bracket comprises: two half shafts (1, 1 ') that make up the pedal axis; a secondary axis (2); four elliptical gears (3, 4, 5, 6); rolling elements (8) and others that are required for assembly; and, as a structural and protective element of the previous mechanisms, a subframe (7).
El cuadro de la bicicleta (0) o chasis en el que se acopla o integra este nuevo pedalier ha de disponer de un único alojamiento especial (0') con las dimensiones necesarias para la incorporación de este mecanismo que conforma el nuevo pedalier.The frame of the bicycle (0) or chassis in which this new bottom bracket is attached or integrated must have a single special housing (0 ') with the dimensions necessary for the incorporation of this mechanism that forms the new bottom bracket.
El subchasis (7) es similar a los que se usan en las bicicletas convencionales para el eje de pedalier, el cual se acopla en el alojamiento especial (0') del cuadro anteriormente citado, y da cobertura y posicionamiento a los engranajes (3, 4, 5, 6) y elementos de rodadura (8). El subchasis (7) puede estar dividido en tantas partes como sea necesario, y bien puede ser una estructura completamente independiente del cuadro de la bicicleta, o bien que sea el propio alojamiento (0') del cuadro el que complete el cierre del pedalier, siendo así esta parte (0') del cuadro parte integrante del subchasis (7).The subframe (7) is similar to those used in conventional bicycles for the bottom bracket, which engages in the special housing (0 ') of the aforementioned frame, and gives coverage and positioning to the gears (3, 4, 5, 6) and rolling elements (8). The subframe (7) can be divided into as many parts as necessary, and it can be a structure completely independent of the bicycle frame, or it is its own housing (0 ') of the frame which completes the closing of the bottom bracket, thus being this part (0') of the frame integral part of the subframe (7).
La disposición de dichos elementos es la siguiente: Cada semieje (1, 1') incorpora 5 solidariamente uno de los engranajes elípticos (3,6) coincidiendo uno de los focos de la elipse primitiva de los engranajes en dicho semieje. Los otros dos engranajes elípticos (4,5) se montan en el eje secundario (2), haciendo coincidir igualmente uno de los focos de la elipse correspondiente a cada engranaje sobre dicho eje secundario y de forma que son solidarios entre ellos, estandoThe arrangement of said elements is as follows: Each half-shaft (1, 1 ') incorporates one of the elliptical gears (3,6) in solidarity with one of the foci of the primitive ellipse of the gears in said half-shaft. The other two elliptical gears (4,5) are mounted on the secondary axis (2), also matching one of the foci of the ellipse corresponding to each gear on said secondary axis and so that they are integral with each other, being
10 desfasados 180°. Los dos semiejes (1 , 1') están alineados, formando el eje de pedales y el eje secundario (2) queda paralelo a este, de forma que los engranajes (3, 4, 5, 6) engranan dos a dos. Con esto se consigue la relación de transmisión deseada entre ambos semiejes: cuando el eje secundario se mueva con velocidad angular constante, cada uno de los semiejes, y por tanto las bielas10 180 ° out of phase. The two half shafts (1, 1 ') are aligned, forming the pedal axis and the secondary axis (2) is parallel to it, so that the gears (3, 4, 5, 6) engage two by two. This achieves the desired transmission ratio between both axles: when the secondary axis moves with constant angular speed, each of the axles, and therefore the connecting rods
15 y pedales, girarán con velocidades senoidalmente variables, de forma que los pedales alcancen la máxima velocidad durante la subida (cuando la pierna flexiona), y la velocidad mínima durante la bajada (cuando la pierna se extiende).15 and pedals, will rotate with sinusoidally variable speeds, so that the pedals reach the maximum speed during the ascent (when the leg flexes), and the minimum speed during the descent (when the leg is extended).
El elemento estructural o subchasis (7) conforma un compartimento estanco y 20 aloja los elementos de rodadura (8) que permiten el posicionamiento de los ejes (1 , 1', 2 ), manteniendo la independencia de los semiejes (1 , 1'), y su sincronización a través del engrane por medio del eje secundario (2). Los extremos de ambos semiejes (1 , 1') saldrán necesariamente al exterior del subchasis (7) para permitir su acoplamiento con las bielas correspondientes: (10, 25 11 ) en el mecanismo de una sola cadena; o bien dos bielas (10) con platos (12) para el de dos cadenas. De esta forma se evita el acoplamiento directo biela- engranaje puesto que si van los engranajes en el exterior del cuadro, al menos una de las bielas tiene que dar arrastre al engranaje junto a ella para lo cual, lejos de ser una biela estándar, necesita una geometría especial que permita el anclaje 30 del engranaje. Con este nuevo pedalier, cada biela y su correspondiente engranaje quedan unidos por medio de cada semieje (1 ,1'), y de esta forma se simplifica el diseño de las bielas que, al igual que las convencionales, necesitan el correspondiente alojamiento para el empotramiento del extremo del eje.The structural element or subframe (7) forms a watertight compartment and 20 houses the rolling elements (8) that allow the positioning of the axles (1, 1 ', 2), maintaining the independence of the semi-axles (1, 1') , and its synchronization through the gear by means of the secondary axis (2). The ends of both axles (1, 1 ') will necessarily come out of the subframe (7) to allow their coupling with the corresponding connecting rods: (10, 25 11) in the single chain mechanism; or two connecting rods (10) with plates (12) for that of two chains. In this way, the direct linkage of the gearbox is avoided since if the gears go outside the frame, at least one of the connecting rods has to drive the gear next to it, for which, far from being a standard connecting rod, it needs a special geometry that allows the anchor 30 of the gear. With this new bottom bracket, each connecting rod and its corresponding gear are joined by means of each semi-axle (1, 1 '), and in this way the design of the connecting rods is simplified which, like conventional ones, need the corresponding housing for the shaft end recess.
Como característica adicional se incluye, en la variante de realización preferida, la posibilidad de reglaje de la distancia entre el eje secundario (2) y los semiejes (1 , 1 '), con el fin de ajustar y regular el juego entre los engranajes. Una posibilidad para conseguirlo es el posicionamiento de los elementos de rodadura (8) correspondientes al eje secundario (2) sobre piezas excéntricas (9) que al ser giradas acerquen o alejen los ejes.As an additional feature, the possibility of adjusting the distance between the secondary axis (2) and the semi-axles (1, 1 ') is included in the preferred embodiment variant, in order to adjust and adjust the play between the gears. One possibility to achieve this is the positioning of the rolling elements (8) corresponding to the secondary axis (2) on eccentric parts (9) which, when turned, bring the axles closer or further away.
El modelo matemático y fundamento mecánico del mecanismo descrito forma parte del estado de la técnica, al estar recogido en las solicitudes P9501429 y P9601579, de las cuales depende directamente la presente solicitud. Así, según se haga uso de una sola cadena y conjunto de platos según la solicitud P9601579 o de dos según la solicitud P9501429, el descentramiento de los platos ha de ser el doble que la excentricidad de los engranajes (3, 4, 5, 6), o bien estar ligeramente por encima de ese valor, en cada uno de los casos.The mathematical model and mechanical basis of the mechanism described is part of the state of the art, as it is included in applications P9501429 and P9601579, upon which the present application depends directly. Thus, depending on the use of a single chain and set of plates according to the application P9601579 or two according to the application P9501429, the offset of the plates must be twice the eccentricity of the gears (3, 4, 5, 6 ), or be slightly above that value, in each case.
Al igual que los mecanismos reivindicados en las solicitudes P9501429 y P9601579, podrán usarse engranajes circulares descentrados sustituyendo a los elípticos, de forma que el descentramiento sea igual a la distancia del foco al centro de la elipse primitiva del engranaje elíptico que sustituye.Like the mechanisms claimed in applications P9501429 and P9601579, off-center circular gears may be used replacing the ellipticals, so that the offset is equal to the focus distance to the center of the primitive ellipse of the elliptical gear that it replaces.
El sistema descrito supone notables mejoras sobre las soluciones mecánicas registradas en las solicitudes P9501429 y P9601579; así, las diferentes ventajas del uso de este pedalier son las siguientes:The system described implies significant improvements over the mechanical solutions recorded in applications P9501429 and P9601579; Thus, the different advantages of using this bottom bracket are as follows:
- Se consigue un único diseño que permite ser usado en bicicletas o máquinas de tracción por pedales, tanto con dos cadenas y dos conjuntos de platos excéntricos, como con una cadena y un conjunto de platos excéntricos.- A unique design is achieved that allows it to be used on bicycles or pedal traction machines, both with two chains and two sets of eccentric plates, as with a chain and a set of eccentric plates.
- Al ser un sistema que alberga los engranajes (3, 4, 5, 6) en su interior permite mantenerlos limpios y engrasados durante más tiempo que si se encuentran en el exterior del cuadro, además de evitarse la posibilidad de accidentes por introducción en los engranajes de elementos extraños que podrían producir daños tanto al mecanismo como incluso al propio usuario.- Being a system that houses the gears (3, 4, 5, 6) inside it allows them to be kept clean and greased for longer than if they are in the outside the frame, in addition to avoiding the possibility of accidents due to the introduction of gears of foreign elements that could cause damage to both the mechanism and even the user.
- Se evita el uso de un carenado o carcasa destinada a cubrir los engranajes en el exterior, con lo que se simplifica la fabricación y montaje, se ahorran costes, y al mismo tiempo se incrementa la protección conseguida para el conjunto de engranajes (3, 4, 5, 6), dada la mayor resistencia a impactos y mejor estanqueidad conseguidas.- The use of a fairing or housing intended to cover the gears outside is avoided, which simplifies manufacturing and assembly, saves costs, and at the same time increases the protection achieved for the gear set (3, 4, 5, 6), given the greater resistance to impacts and better sealing.
- Se evita la unión directa biela-engranaje. Con la nueva solución, la unión directa biela-engranaje se sustituye por una unión biela-eje de pedalier de tipo tradicional, lo que facilita el uso de una biela estandarizada. Esto implica ventajas en la fabricación y baja los costes de producción del sistema.- Direct connecting rod-gear connection is avoided. With the new solution, the direct connecting rod-gear is replaced by a connecting rod-bottom bracket of the traditional type, which facilitates the use of a standardized connecting rod. This implies advantages in manufacturing and lowers the production costs of the system.
- Se consigue una importante mejora en precisión al usar una estructura (7) que posiciona los ejes independientemente del cuadro de la bicicleta (o el chasis de la máquina), dado que se evita que sea el cuadro de la bicicleta, mediante dos alojamientos paralelos, el que posicione los ejes condicionando su paralelismo. Esta es una importante ventaja ya que la mayoría de cuadros de bicicleta son fabricados por soldadura de tubos, lo que da lugar tanto a deformaciones no deseadas como al sobrecoste que suponen, en el caso de cuadros con dos alojamientos para ejes, operaciones posteriores a la soldadura para conseguir el paralelismo entre dichos ejes.- A significant improvement in precision is achieved by using a structure (7) that positions the axles independently of the frame of the bicycle (or the chassis of the machine), since it is avoided that it is the frame of the bicycle, by means of two parallel housings , the one that positions the axes conditioning its parallelism. This is an important advantage since most bicycle frames are manufactured by welding tubes, which leads to both unwanted deformations and cost overruns that involve, in the case of frames with two axle housings, operations after the welding to achieve the parallelism between these axes.
Las citadas mejoras redundan en una mayor simplicidad y fiabilidad mecánica (minimizando además los riesgos de posibles accidentes), un ahorro de costes, y una mayor facilidad de producción y montaje, y por tanto, en una mayor aplicabilidad industrial de la invención. The aforementioned improvements result in greater simplicity and mechanical reliability (also minimizing the risks of possible accidents), cost savings, and greater ease of production and assembly, and therefore, in greater industrial applicability of the invention.
