An energy damping device that includes a piston-cylinder assembly (12) having a cylinder and a piston (22) movable therein. A pre-loaded double acting spring (12), and a friction assembly (14), are enclosed fully within the cylinder, and engage the piston concentrically. The spring acts against the friction assembly for forcing it into frictional engagement with the inner surface of the cylinder. The friction assembly includes at least one wedge (25) for engaging the interior surface of the cylinder. The friction assembly further includes a plurality of spaced-apart compression rings (30,33,36), that are interleaved with the wedges, for forcing them into radially outwardly directed frictional engagement with the interior surface of the cylinder.
Cette invention concerne un amortisseur comportant un système (12) de cylindre et de piston, le piston (22) se déplaçant dans le cylindre. Le cylindre renferme également un ressort taré à double effet (12) et un dispositif à friction (14), disposés autour du piston. Le ressort pousse le dispositif à friction contre la paroi interne du cylindre. Le dispositif à friction comporte au moins un élément en forme de coin (25) destiné au contact avec la paroi interne du cylindre, ainsi qu'une série de rondelles de compression (30, 33, 36) intercalées entre les coins et servant à pousser ces derniers radialement pour qu'ils s'appliquent contre la paroi interne du cylindre.
