Abstract

UN SISTEMA HIDRAULICO (1) PARA CONTROLAR LA ROTACION DE UNA ESTRUCTURA DE VAGON DE TREN (2), Y QUE PRESENTA UN CONJUNTO DE BOMBA DE MOTOR (8) CONECTADO A UN DEPOSITO DE LIQUIDO HIDRAULICO (7) Y A UNA LINEA DE ABASTECIMIENTO (14); UN NUMERO DE ACTUADORES HIDRAULICOS (3A, 3B, 4A, 4B) PARA EJERCER FUERZA MECANICA EN LA ESTRUCTURA (2) PARA GIRARLA; UNA VALVULA DE SOLENOIDE (26) PARA CONECTAR SELECTIVAMENTE LOS ACTUADORES HIDRAULICOS (3A, 3B, 4A, 4B) A LA LINEA DE ABASTECIMIENTO (14) O PARA UN DRENAJE (29) EN RESPUESTA A LAS SEÑALES DE CONTROL ELECTRICAS; Y UN DISPOSITIVO (61) PARA DESPRESURIZAR LOS ACTUADORES (3A, 3B, 4A, 4B) Y QUE INHABILITA EL SISTEMA AL FINAL DEL PERIODO DE TRABAJO O EN CASO DE EMERGENCIA. EL DISPOSITIVO (61) PRESENTA DOS VALVULAS DE INHABILITACION, HIDRAULICAMENTE ACCIONADAS, NORMALMENTE ABIERTAS (47) INTERPUESTAS ENTRE PARES CORRESPONDIENTES DE ACTUADORES (3A, 4A; 3B, 4B) Y EL DRENAJE (29), Y QUE PRESENTAN LINEAS DE IMPULSION CORRESPONDIENTES (59) CONECTADAS A LA LINEA DEABASTECIMIENTO (14); Y UN DISTRIBUIDOR ELECTRICO (46) PARA DESPRESURIZAR LAS LINEAS DE IMPULSION (59).A HYDRAULIC SYSTEM (1) TO CONTROL THE ROTATION OF A TRAIN WAGON STRUCTURE (2), AND WHICH PRESENTS AN ENGINE PUMP ASSEMBLY (8) CONNECTED TO A HYDRAULIC LIQUID TANK (7) AND A SUPPLY LINE (14 ); A NUMBER OF HYDRAULIC ACTUATORS (3A, 3B, 4A, 4B) TO EXERCISE MECHANICAL FORCE IN THE STRUCTURE (2) TO TURN IT; A SOLENOID VALVE (26) TO SELECTLY CONNECT THE HYDRAULIC ACTUATORS (3A, 3B, 4A, 4B) TO THE SUPPLY LINE (14) OR FOR A DRAIN (29) IN RESPONSE TO ELECTRICAL CONTROL SIGNALS; AND A DEVICE (61) TO DEPRESSORIZE THE ACTUATORS (3A, 3B, 4A, 4B) AND THAT DISABLES THE SYSTEM AT THE END OF THE WORKING PERIOD OR IN CASE OF EMERGENCY. DEVICE (61) FEATURES TWO HYDRAULICALLY OPERATED, NORMALLY OPEN DISABLING VALVES (47) INTERPOSED BETWEEN CORRESPONDING PAIRS OF ACTUATORS (3A, 4B; 4B) AND DRAINAGE LINES (29) ) CONNECTED TO THE SUPPLY LINE (14); AND AN ELECTRICAL DISTRIBUTOR (46) TO DEPRESSURIZE THE DRIVE LINES (59).
