Abstract

L’invention concerne une butée de suspension de véhicule automobile, comprenant au moins une chambre annulaire (6) qui est délimitée latéralement par deux parois (1a, 2a), ainsi qu’un élément d’étanchéité interne (8i) qui est solidaire d’une première paroi (1a) en présentant un déflecteur externe (9b) disposé dans une section externe (6e) de ladite chambre, ladite butée comprenant un élément d’étanchéité externe (8e) qui présente deux portées d’étanchéité (11a, 11b) et est monté mobile dans la section externe (6e) entre une position stable dans laquelle lesdites portées d’étanchéité sont disposées à distance de portées complémentaires (12a, 12b) de respectivement la deuxième paroi (2a) et du déflecteur externe (9b) et une position contrainte par appui sur ledit élément d’étanchéité externe dans laquelle lesdites portées d’étanchéité sont plaquées sur respectivement une desdites portées complémentaires pour assurer l’étanchéité de la section externe (6e). Figure 3aThe invention relates to a suspension stop for a motor vehicle, comprising at least one annular chamber (6) which is delimited laterally by two walls (1a, 2a), as well as an internal sealing element (8i) which is integral with 'a first wall (1a) having an outer baffle (9b) disposed in an outer section (6e) of said chamber, said stopper comprising an outer sealing element (8e) which has two sealing surfaces (11a, 11b ) and is movably mounted in the outer section (6e) between a stable position in which said sealing surfaces are arranged at a distance from complementary surfaces (12a, 12b) of respectively the second wall (2a) and the external deflector (9b) and a constrained position by pressing on said external sealing element in which said sealing surfaces are pressed against respectively one of said complementary surfaces to ensure the sealing of the external section (6e).
