Abstract

SE PRESENTA UN SISTEMA (230)/METODO DE CONTROL DEL CAMBIO DE VELOCIDAD DE LA SECCION DE TRANSMISION AUXILIAR (14) QUE INCLUYE UNA VALVULA DE PRESION RESIDUAL (246) Y UNA VALVULA DE DESAHOGO DE FLUJO RESTRINGIDO UNIDIRECCIONAL (250) PARA PREVENIR QUE SE DAÑE UN EMBRAGUE SINCRONIZADO DE LA RELACION DE ALTA VELOCIDAD DE SECCION AUXILIAR (92) SI LA SECCION DE TRANSMISION PRINCIPAL (12) SE ENGANCHA DURANTE UN CAMBIO ASCENDENTE DE LA SECCION AUXILIAR. LA CAMARA (224A) DEL ACCIONADOR (220) ASOCIADA AL EMBRAGUE SINCRONIZADOR DE ALTA VELOCIDAD SE VENTILA GRADUALMENTE DE MANERA CONSTANTE, HASTA QUE ALCANCE UNA PRESION DE REFERENCIA, A TRAVES DE UN ORIFICIO MUY ESTRECHO QUE SE ENCUENTRA EN LA VALVULA DE DESAHOGO DE FLUJO RESTRINGIDO UNIDIRECCIONAL (250) Y LA VALVULA DE PRESION RESIDUAL (246) BLOQUEARA LA CIRCULACION DE FLUIDOS DESDE LA FUENTE (234) A LA VALVULA SECUNDARIA (238) SIEMPRE QUE LA SECCION DE TRANSMISION PRINCIPAL CAMBIE A UNA CONDICION NEUTRA DE LA MISMA. SEGUN ESTO, SIEMPRE QUE SE INTENTEUN CAMBIO ASCENDENTE DE LA SECCION AUXILIAR MIENTRAS LA SECCION DE TRANSMISION PRINCIPAL NO SE ENCUENTRA EN LA POSICION NEUTRA, EL ACCIONADOR (222) EJERCERA UNA FUERZA GRADUALMENTE REDUCIDA DESDE UNA PRIMERA FUERZA ELEVADA A UNA SEGUNDA FUERZA MENOR EN EL EMBRAGUE DE RELACION DE ALTA VELOCIDAD PARA PREVENIR O MINIMIZAR LOS DAÑOS EN EL MISMO.
