Abstract
Una unidad de control de rodillos para una transmisión de relación continuamente variable, la cual está compuesta de: un cilindro (54) que tiene una pared del cilindro (56); un pistón (70) que tiene una superficie exterior y que está dispuesto en el cilindro (54) y axialmente transferible por allí; una primera cámara (66, 68) formada por dichos cilindro (54) y pistón (70) para recibir fluido hidráulico, el cual, en operación, hace que dicho pistón (70) se mueva entre la primera y la segunda posición desplazada axialmente; y un pasaje de suministro de lubricación (71), el cual consta de una cámara de lubricación (94) que recibe el fluido de lubricación de una fuente de fluido hidráulico presionizado y proporciona un fluido de lubricación a un rodillo que está conectado a dicho pistón (70) para moverse con el mismo, caracterizándose por el hecho de que dicha cámara de lubricación (94) se forma entre la superficie exterior de dicho pistón (70) y dicha pared del cilindro (56), y uno o más pasajes que se extienden radialmente (102) se facilitan a través de dicho pistón (70), cada uno de ellos teniendo un primer extremo (102a) que comunica el fluido con dicha cámara de lubricación (94) y teniendo un segundo extremo (102b) que se comunica con dicho rodillo.
