Abstract

UN DISPOSITIVO DE CONTROL PARA UNA CAJA DE CAMBIOS DE UN VEHICULO A MOTOR, PARTICULARMENTE PARA UN TRACTOR, TENIENDO EL DISPOSITIVO UNA SOLA PALANCA DE CAMBIO (1) PARA OPERAR UN VARIADOR MECANICO CON VARIOS NIVELES DE CAMBIO (I, II, III) Y UN VARIADOR MECANICO CON DOS LIMITES DE CAMBIO (L, V) COLOCADOS EN SERIES. EN ORDEN A ENGANCHAR UNO U OTRO DE LOS LIMITES DE CAMBIO (L, V), LA PALANCA (1) PUEDE SER SITUADA EN DOS POSICIONES CORRESPONDIENTES, SITUADAS EN LADOS OPUESTOS DE LA LINEA DE SELECCION (5) QUE COINCIDE CON LAS POSICIONES NEUTRALES (N) DE LA PALANCA, Y MEDIOS MECANICOS (9, 13) SON PROVISTOS, PARA MANTENER PERMANENTEMENTE CADA LIMITE DE CAMBIO SELECCIONADO, PUDIENDO ESTOS SER LIBERADOS COMO RESULTADO DE LA SELECCION DEL OTRO LIMITE. UN SISTEMA DE SEGURIDAD (17) ESTA PROVISTO, PARA PREVENIR LOS ENGANCHES NO QUERIDOS O ACCIDENTALES DE LA PALANCA DE CAMBIO (I).
