Abstract

Sistema de amortiguamiento controlado electrónicamente con leyes cruzadas El interior del vástago de accionamiento del pistón del amortiguador hidráulico, está ocupado por una válvula rotativa de control (2) movida angularmente por un motor eléctrico activado por un calculador electrónico en función del estado de movimiento del vehículo, teniendo dichos vástago y válvula rotativa una serie de orificios que pueden entrar en comunicación y teniendo el pistón principal (3) unas válvulas de paso (7, 8) que permiten o no el paso de aceite de una cámara del cilindro a otra. Además del pistón principal (3) se prevén otros dos pistones secundarios primero (14) y segundo (21). El pistón principal (3) tiene dobles parejas de orificios (5, 6) pasantes y obturables por válvulas (7, 8) de ambas caras del mismo. El primer pistón secundario (14) se relaciona con orificios (9, 10) del vástago (1) y con orificios (29, 31) de la varilla de control (2). El segundo pistón secundario (21) se relaciona también con otros dos orificios (27, 28) del vástago (1) y con los orificios (30, 32) de la varilla de control (2). Se consiguen pasos distintos y en diferente número para una posición determinada de la varilla de control (2), siendo éstos controlados por cierres elásticos en base a válvulas y muelles helicoidales independientes entre sí.
