Abstract

Una transmision hidrostática continuamente variable (10) incluye una flecha de entrada (14) conectada para impulsar una unidad de bomba hidráulica (18), una unidad de motor hidráulico a tierra (20), y una flecha de salida (16). Se monta pivotalmente una placa motriz en forma de cuña (22) en la flecha de salida (16), en una conexion de impulso para recibir el par de torsion de salida resultante del intercambio de fluido hidráulico presurizado entre las unidades de bomba (18) y un motor (20) a través de compuertas especialmente configuradas en la placa motriz (22). Un controlador de relacion hidráulicamente accionado cambia las posiciones axiales de los baleros esféricos (86, 96) que montan un bloque de cilindros de bomba (88) en la unidad de bomba hidráulica (18), y un bloque de cilindros de motor (100) en la unidad de motor hidráulico (20), para ajustar el ángulo de la placa motriz en relacion con el eje de la flecha de salida (25), y cambiar de esta manera la relacion de la transmision.
