Abstract

SE PRESENTA UN SISTEMA DE ACCIONAMIENTO HIDRAULICO QUE INCORPORA UNA BOMBA HIDRAULICA (2) PARA VEHICULOS DE TRES RUEDAS TALES COMO CARRETILLAS ELEVADORAS DEL TIPO "PIGGY BACK" EN LAS CUALES HAY AL MENOS DOS UNIDADES MOTRICES SEPARADAS PERO ACOPLADAS (11 Y 12; 21 Y 22; 31 Y 32) QUE FORMAN UNA SOLA UNIDAD MOTRIZ (10, 20, 30) PARA CADA UNA DE LAS RUEDAS, Y CADA UNIDAD MOTRIZ (11, 12, 21, 22, 31 Y 32) TIENE UNA ENTRADA Y UNA SALIDA SEPARADAS. SE SUMINISTRAN VALVULAS PARA PERMITIR UN FUNCIONAMIENTO TANTO PARALELO COMO EN SERIE DEL SISTEMA PARA OBTENER UN PAR, UNA VELOCIDAD Y UN FUNCIONAMIENTO ANTIDERRAPE OPTIMOS. EN UNA FORMA PREFERIDA DE LLEVAR A CABO LA INVENCION, UNA SOLA UNIDAD MOTRIZ (10) ALIMENTA UNA DE LAS UNIDADES MOTRICES (22, 32) DE CADA UNA DE LAS OTRAS UNIDADES MOTRICES. LA BOMBA HIDRAULICA (2) ALIMENTA LA UNIDAD MOTRIZ SIMPLE (10) Y UNA DE LAS UNIDADES MOTRICES (21, 22) DE LAS OTRAS UNIDADES MOTRICES TRANSVERSALES (20, 30). SE MONTAN VALVULAS DE DESVIO EN BY-PASS (23, 33) A TRAVES DE LAS UNIDADES MOTRICES (22, 33) DE LAS UNIDADES MOTRICES TRANSVERSALES (20, 30).
