Abstract

MANDO ELECTRO-HIDRAULICO PARA UN CAMBIO DE VELOCIDADES PARA AUTOMOVILES DE CONEXION AUTOMATICA CON UNA CORREDERA DE SELECCION (2), AL MENOS PARA LA POSICION NEUTRA (N), ASI COMO PARA LA MARCHA DE AVANCE (D) Y LA MARCHA DE RETROCESO (R), UN APARATO DE MANDO ELECTRONICO (3) CON VALVULAS MAGNETICAS (4), QUE SE MANTIENEN EN POSICION NEUTRA POR LA ACCION DE LA FUERZA ELASTICA, UNA FUENTE DE AGENTE DE PRESION (1), VALVULAS DE MANDO Y DE CONEXION DE PRESION (5, 6, 7) PARA ACCIONAR LOS EMBRAGUES DE CAMBIO DE MARCHA Y FRENOS (A-F), ASI COMO UNA VALVULA DE SEGURIDAD DE LA MARCHA ATRAS (8) PARA EVITAR LA INTRODUCCION DE LA MARCHA ATRAS CUANDO LA VELOCIDAD DE MARCHA EN AVANCE ES TODAVIA DEMASIADO ELEVADA Y UN DISPOSITIVO QUE, AL FALLAR EL SISTEMA ELECTRONICO, MANTIENE O CONECTA EL CAMBIO AUTOMATICO EN UNA MARCHA QUE GARANTIZA QUE, A LA MAXIMA VELOCIDAD DE MARCHA POSIBLE, NO SE REBASE EL NUMERO DE REVOLUCIONES MAXIMO PERMITIDO DEL MOTOR, A CUYO EFECTO EN CASO DE AVERIA DEL APARATO DE MANDO ELECTRONICO (3) DURANTE EL RECORRIDO SE MANTIENE O CONECTA POR MEDIO DE UN DISPOSITIVO DE MANDO Y AL FALLAR EL APARATO DE MANDO ELECTRONICO (3), ANTES DEL ARRANQYE O NUEVO ARRANQUE DEL MOTOR, SE INTRODUCE UNA MARCHA MAS CORTA POR MEDIO DE ESTE DISPOSITIVO DE MANDO (5, 6, 7, 8, 9). SI FALLA EL SISTEMA ELECTRONICO DURANTE EL RECORRIDO, SE PUEDE CONTINUAR POR TANTO EL VIAJE SIN DIFICULTAD ALGUNA INCLUSO, POR EJEMPLO, CON LA MARCHA MAS LARGA, SIN QUE ELLO OCASIONE RETROCESO ALGUNO. EN CASO DE FALLAR EL SISTEMA ELECTRONICO EN EL ARRANQUE O NUEVO ARRANQUE DEL MOTOR DESPUES DE FALLAR DURANTE EL RECORRIDO, SE CAMBIARA A UNA MARCHA MAS CORTA EN LA QUE TAMBIEN ES POSIBLE LA PUESTA EN MARCHA.
