Abstract

Un amortisseur comprend un cylindre dans lequel une tige de piston est montée axialement mobile par l'intermédiaire d'un guide de tige de piston, un ressort hélicoïdal de butée de course de déplacement agissant à partir d'une position de course de déplacement définie, et étant relié au cylindre par complémentarité de forme en vue de sa fixation à celui-ci ; le cylindre 3 présente au moins partiellement une résistance à la déformation qui est dimensionnée de façon à ce que pour une position de butée de course de déplacement de la tige de piston 5, il apparaît, en raison des augmentations de diamètre du diamètre de spire du ressort de butée de course de déplacement, qui y sont liées, un profil 23 de liaison par complémentarité de forme, à l'intérieur du cylindre 3.A shock absorber comprises a cylinder in which a piston rod is mounted axially movable by means of a piston rod guide, a helical spring for travel travel stop acting from a defined travel travel position, and being connected to the cylinder by complementarity of shape for its attachment thereto; the cylinder 3 has at least partially a resistance to deformation which is dimensioned so that for a position of travel stroke stop of the piston rod 5, it appears, due to the increases in diameter of the turn diameter of the displacement travel stop spring, which are linked to it, a profile 23 of connection by complementarity of shape, inside the cylinder 3.
