Abstract

Para controlar la relacion de transmision de una transmision hidrostática continuamente variable que incluye una flecha de entrada (14), una flecha de salida (16), una unidad de bomba (18) impulsada por la flecha de entrada (14), una unidad de motor a tierra (20), y una placa motriz en forma de cuña (22) conectada de una manera impulsable y pivotal con la flecha de salida (16) en una posicion de comunicacion del fluido hidráulico entre las unidades de bomba y de motor (18, 20), se proporciona un controlador de relacion que tiene un piston hidráulicamente accionado (128) incorporado internamente en la flecha de salida (16). También se incorpora una válvula piloto (150) internamente en la flecha de salida (16), que opera para crear presiones diferenciales de fluido en las caras de extremo opuestas del piston (128), forzando el movimiento axial del piston y el movimiento pivotal que cambia la relacion de la placa motriz (22) enlazada con el piston.
