Abstract

TRANSMISION (1) PARA UN TRACTOR AGRICULTOR, CON GRAN NUMERO DE ENGRANAJES Y QUE CONSTA DE UN PRIMER ESTADO EN SEXTA MARCHA (2) Y UN SEGUNDO ESTADO REDUCTOR Y DE MARCHA ATRAS (3) CON TRES RANGOS DE VELOCIDAD HACIA ADELANTE Y UNO HACIA ATRAS. EL PRIMER ESTADO (2) CONSTA DE UN PAR DE EJES CONDUCTORES (4,5) QUE SE CONECTAN SELECTIVAMENTE A UN EJE DE ENTRADA (12) POR MEDIO DE EMBRAGUES HIDRAULICOS RESPECTIVOS (FP,FD) Y A UN EJE DE SALIDA (16) POR MEDIO DE ENGRANAJES CONSTANTES (R1,R''1,R3,R''3,R5,R''5,R2,R''2,R4,R''4,R6,R''6) QUE DEFINEN RESPECTIVAMENTE EL NUMERO IMPAR O PAR DE ENGRANAJES, Y QUE SE CONECTAN AL EJE DE SALIDA (16) POR MEDIO DE ACOPLAMIENTOS DESLIZANTES (M13,M52,M46) CONTROLADOS POR ACCIONADORES HIDRAULICOS DE TRES POSICIONES (A13,A52,A46). DICHOS ACCIONADORES SE VEN DIRIGIDOS POR PARES RESPECTIVOS DE VALVULAS SOLENOIDES ON-OFF (E1,E3;E5,E2;E4,E6) SUMINISTRADAS POR UNA VALVULA SOLENOIDE DE RESPUESTA PRORPORCIONAL (E8,E9) QUE CONTROLAN EL ACOPLAMIENTO Y LIBERACION DE LOS EMBRAGUES MENCIONADOS (FP,FD). TODAS LAS VALVULAS SOLENOIDES MENCIONADAS (E1,...,E9) SON CONTROLADAS POR UNA UNIDAD DE CONTROL ELECTRONICO (45) QUE CONTROLA EL ACOPLAMIENTO APROPIADO DE LOS EMBRAGUES (FP,FD) Y DE LOS ACCIONADORES (A13,A52,A46) COMO UNA DE LAS FUNCIONES DE LAS CONDICIONES DE SERVICIO ACTUALES DEL TRACTOR. (FIGURAS 1 Y 2).
