Abstract

UNA SUSPENSION ACTIVA PARA UN VEHICULO INCLUYE UNA ARMADURA (10) QUE SE COMPONE DE UN PISTON (12) QUE OPERA DENTRO DE UN CILINDRO (11) Y PUEDE MOVERSE PARA COMPENSAR EN LA SUSPENSION ENTRADAS IMPREVISTAS EN EL CAMINO Y ENTRADAS GENERADAS POR EL CONDUCTOR, TALES COMO FUERZAS INERCIALES INTRODUCIDAS POR EL FRENADO O AL DOBLAR BRUSCAMENTE. MUCHAS VECES CUANDO SE MUEVE EL PISTON (12) POR EL CAMINO Y LAS ENTRADAS DEL CONDUCTOR A LA ARMADURA (10) SE ALIMENTA UN EXCESO DE FLUIDO HIDRAULICO DESDE LA ARMADURA (10) A UNA ACUMULADOR (33) DONDE SE ALMACENA TEMPORARIAMENTE A ELEVADA PRESION Y LUEGO SE LIBERA NUEVAMENTE HACIA LA ARMADURA (10) CUANDO SE DESEE AUMENTAR LA LONGITUD DE LA ARMADURA. DE ESTA MANERA, UNA PARTE, Y A VECES TODA, LA ENERGIA NECESARIA PARA EXTENDER LA ARMADURA (10) PUEDE SUMINISTRARSE MEDIANTE EL ACUMULADOR (33) EN LUGAR DE LA BOMBA (P). ESTO IMPLICA UN AHORRO DE ENERGIA. EL PISTON (12) TIENE AREAS DESIGUALES Y SE PROVEE UN SISTEMA DE VALVULAS DE CARRETE (32, 39) PARA CONTROLAR EL FLUJO DE FLUIDO ENTRE LA ARMADURA (10), EL ACUMULADOR (33), Y LA BOMBA (P).
