Abstract

Una transmisión infinitamente variable de derivación de potencia con dos modos de funcionamiento, cuyos elementos constitutivos están repartidos entre dos vías de potencia que unen en paralelo el motor térmico (1) con las ruedas (3) del vehículo, de tal modo que estos medios incluyen al menos dos primeros trenes epicicloidales (5, 6), dos máquinas eléctricas (2, 4) y una etapa de reducción (11), caracterizada por que comprende unos órganos de gobierno (8, 9), que cooperan con un tercer tren epicicloidal (7) para establecer los dos modos de funcionamiento de la transmisión y para conmutar entre éstos últimos, por acoplamiento simultáneo durante la fase transitoria de cambio de modo.

Description

Transmisión de relación infinitamente variable con derivación de potencia con dos modos de funcionamiento, que comprende tres trenes epicicloidales.
La presente invención se refiere a una transmisión de derivación de potencia que permite obtener una variación continua de relación de marcha atrás a marcha adelante, pasando por una posición concreta, denominada "de toma neutra", en la que la velocidad de desplazamiento del vehículo es nula, para un régimen cualquiera del motor térmico.
Más precisamente, tiene por objeto una transmisión infinitamente variable de derivación de potencia con dos modos de funcionamiento, cuyos elementos constitutivos se encuentran repartidos entre dos vías de potencia que unen en paralelo el motor térmico a las ruedas del vehículo, de tal modo que estos medios incluyen al menos dos trenes epicicloidales, dos máquinas eléctricas y una etapa de reducción.
Se conoce por la publicación FR 2.823.156 una transmisión del tipo indicado en lo anterior, en la cual los dos modos de funcionamiento se establecen a través de dos etapas de reducción montadas en paralelo entre los dos trenes epicicloidales, y que son solicitadas, respectivamente, en el primer y en el segundo modos de funcionamiento.
La presente invención tiene como propósito modificar dicha transmisión de manera que se la haga más compacta, se reduzca su coste y se facilite su integración en el vehículo.
Con este fin, ésta propone reemplazar las etapas de reducción paralelas de la vía de derivación de potencia por un tercer tren epicicloidal.
De conformidad con la invención, este tercer tren epicicloidal coopera con unos órganos de gobierno con el fin de establecer los dos modos de funcionamiento de la transmisión y para conmutar entre éstos últimos.
De acuerdo con un modo de realización preferida de la invención, el cierre de un primer órgano de gobierno garantiza la inmovilización relativa de los elementos constitutivos del tercer tren y la rotación de forma solidaria o en bloque de éste, y el cierre de un segundo órgano de gobierno garantiza la inmovilización de un elemento del tercer tren con respecto al cárter.
Otras características y ventajas de la presente invención se pondrán de manifiesto claramente a partir de la lectura de la siguiente descripción, al hacer referencia a los dibujos que se acompañan, en los cuales la Figura 1 ilustra esquemáticamente el principio de la invención.
Los elementos constitutivos de esta transmisión se encuentran repartidos entre dos vías de potencia que unen en paralelo el motor térmico 1 con las ruedas 3 del vehículo. De acuerdo con el esquema, estos medios incluyen dos máquinas eléctricas 2, 4, que forman un dispositivo de variación, varios trenes epicicloidales 5, 6, 7, dos órganos de gobierno 8, 9, y varias etapas de reducción 11.
En este esquema se aprecian las dos vías de potencia que unen el motor térmico 1 con las ruedas 3 del vehículo. La primera vía, o vía principal de transmisión de potencia, une la segunda con el primer tren epicicloidal 5. La primera máquina eléctrica 2 une la vía de derivación de potencia con el segundo tren epicicloidal 6. Las dos máquinas eléctricas se encuentran separadas por un tercer tren epicicloidal 7, asociado a sus dos órganos de gobierno 8, 9.
Por último, el motor térmico 1, las ruedas y las dos máquinas eléctricas 2, 4 están unidos a unas etapas de reducción 11 cuya disposición particular, indicada en la Figura, no tiene ningún carácter limitativo para el alcance de la invención, puesto que puede concebirse un número y/o una disposición diferentes de estas etapas de reducción sin apartarse de éste.
Esta transmisión dispone de una vía principal de potencia por la que transita una parte importante del par entre el motor térmico y las ruedas, así como una vía secundaria o de derivación de potencia, en la que están dispuestas las dos máquinas eléctricas que constituyen el dispositivo de variación, de manera que se realiza una transmisión infinitamente variable del par entre el motor y las ruedas.
Esta dispone de dos modos de funcionamiento en los cuales son solicitados, respectivamente, los primeros o los segundos medios de gobierno del tercer tren epicicloidal 8, 9.
Estos dos modos de funcionamiento se encaminan a aumentar el intervalo o margen de funcionamiento de la transmisión infinitamente variable. Corresponden al establecimiento de dos relaciones de desmultiplicación diferentes en el tercer tren epicicloidal 7, gracias a la respectiva solicitación de los primeros y de los segundos medios de gobierno 8, 9 asociados.
La transmisión infinitamente variable que se ilustra en las figuras se denomina de un "punto de adaptación" y de "entrada acoplada", puesto que la derivación de la potencia a la salida del motor térmico está asegurada por un par de piñones de derivación de potencia (no representado), en tanto que la reunión de las dos vías de potencia antes de las ruedas se efectúa en un tren epicicloidal ensamblador 5.
Sin embargo, esta disposición particular no tiene ningún carácter limitativo y la invención se aplica igualmente a cualquier transmisión infinitamente variable de derivación de potencia con salida acoplada, en la cual se tenga un tren divisor de par a la salida del motor y un par de piñones de reunión antes de las ruedas. En las mismas condiciones, la invención puede aplicarse a cualquier transmisión infinitamente variable de derivación de potencia "de dos puntos de adaptación" en la que se tenga un tren epicicloidal divisor de par y un tren de reunión de par (lo que eleva a cuatro el número total de trenes, contando el tren 6, asociado a la segunda máquina eléctrica, y el tren 7 de cambio de modo de funcionamiento).
Como se ha indicado en el esquema, los órganos 8 de cambio de modo están asociados a este tercer tren 7. De conformidad con la invención, estos órganos de gobierno pueden estar constituidos por frenos, embragues o sistemas de engranajes.
De acuerdo con el modo de realización particular de la invención que se ilustra en el esquema, el cierre del primer órgano de gobierno 8 asegura la inmovilización relativa de los elementos constitutivos del tercer órgano y la rotación en bloque de éste, y el cierre del segundo órgano de gobierno 9 garantiza la inmovilización de un elemento del tercer tren con respecto al cárter. Como se ha indicado aquí en lo anterior, el cierre del primer o del segundo órgano de gobierno 7, 8 sitúa, respectivamente, la transmisión en su primer o en su segundo modo de funcionamiento.
En este contexto, una disposición particularmente ventajosa, pero no limitativa de la invención, consiste en disponer el primer órgano de gobierno 8 entre la corona y el elemento porta-satélites del tercer tren 7, y el segundo órgano de gobierno entre el elemento porta-satélites del tercer tren epicicloidal y el cárter.
De esta forma, en el primer modo de funcionamiento, el primer órgano de gobierno 8 está cerrado y el segundo 9 se encuentra abierto. El tren 7 gira en bloque, y la relación de desmultiplicación introducida por éste en la vía de derivación de potencia es igual a uno. En el segundo modo, el primer órgano 8 está abierto y el segundo órgano 9 se encuentra cerrado, de modo que se inmoviliza uno de los elementos constitutivos del tercer tren 7 con respecto al cárter. El tren 7 introduce entonces su relación de desmultiplicación diferente de uno en la vía de derivación de potencia.
Por último, durante el estado transitorio de cambio de modo, los dos órganos de gobierno pueden ser cerrados simultáneamente, situación en la que el tercer tren 7 queda inmovilizado.
En conclusión, el interés de reemplazar las dos etapas de reducción paralelas de la transmisión de derivación de potencia y dos modos de funcionamiento conocidos, por un tercer tren planetario, es obtener una arquitectura o estructura más compacta, en la que los tres trenes pueden estar alineados a lo largo de un mismo eje. En efecto, la solución anterior implica disponer un árbol específico para cada etapa de reducción, en tanto que la invención permite alinear el tercer tren epicicloidal con los dos primeros. Por último, si bien la invención puede ponerse en práctica utilizando frenos, embragues o sistemas de engranajes, el uso de éstos últimos es con mucho el más económico.
