Abstract

Tope de compresión hidráulico para amortiguadores. En los amortiguadores hidráulicos convencionales, tanto del tipo monotubo como bitubo, existe un pistón (3) conectado a un vástago (4) de accionamiento. Se definen dos cámaras: una de expansión o tracción (5) y otra de compresión (6), inundadas de fluido y pasando el aceite de una a otra por orificios calibrados y válvulas existentes en el pistón (3), a consecuencia de los movimientos de elevación y descenso de las ruedas correspondientes. Acorde con la invención se prevén topes de compresión hidráulicos para amortiguar el golpe brusco producido por el paso de la rueda por un resalte. Se origina un aumento de la carga en la cámara de compresión para que se frene el desplazamiento rápida del vástago, al prever en dicha cámara de compresión (6) un émbolo libre (26) asistido por un resorte (24) que le impulsa contra un casquillo de cierre (13) solidaria al extremo del vástago (4). El émbolo (26) tiene un orificio central (27) y otros periféricos calibrados (28), así como unos salientes elásticos frontales (29) con pasos de aceite (30) deformables a compresión. Se forman tres subcámaras (19, 31 y 32) cuyos pasos se cierran sucesivamente al desplazarse el vástago (4).
