Abstract

DISPOSITIVO DE ACCIONAMIENTO PARA LAS CUATRO RUEDAS DE UN VEHICULO TRACTOR. LA VALVULA (24) ES DESEXCITADA PARA LA SELECCION DE LA APLICACION DEL PAR MOTOR A LAS RUEDAS DELANTERAS. ESTA VALVULA ESTA CONTROLADA POR EL CONMUTADOR (25) ACCIONADO POR EL OPERARIO. CUANDO EL MOTOR SE SOBRECARGA Y LA TEMPERATURA DE LOS GASES DE ESCAPE SE ELEVA, EL SENSOR TERMICO (32) INTERRUMPE EL CIRCUITO DEL RELE (31), Y UN SEGUNDO RELE (30) INTERRUMPE EL CIRCUITO DE LA VALVULA SOLENOIDE (24): EL ACCIONAMIENTO A LAS CUATRO RUEDAS SE APLICA AUTOMATICAMENTE. ESTA ACCION QUEDA RESTRINGIDA A UN REGIMEN O INTERVALO DE ENGRANAJES BAJO POR EL CONMUTADOR (29) UNIDO AL MECANISMO DE SELECCION ENTRE EL INTERVALO BAJO (I) Y EL ELEVADO (II).
