Title
(EN) BUMPER CAP FOR DAMPER
(FR) EXTRÉMITÉ DE PARE-CHOCS POUR AMORTISSEUR
Abstract
(EN) A bumper cap for a damper, the damper including an outer tube with a tube end. A rod extending through the tube end. The damper including a damping fluid, such as a hydraulic oil, that is movable within the damper in response to movement of the rod to provide a damping effect. The bumper cap has a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube. The base of the bumper cap has a through hole in the base, the through hole configured to have the rod pass therethrough. The base has at least one fluid passage extending away from the through hole that is in fluid communication with a fluid reservoir in the side wall.
(FR) L’invention concerne une extrémité de pare-chocs pour un amortisseur, l'amortisseur comprenant un tube externe avec une extrémité de tube. Une tige s'étend à travers l'extrémité du tube. L'amortisseur comprend un fluide d'amortissement, tel qu'un liquide hydraulique, qui est mobile à l'intérieur de l'amortisseur en réponse au mouvement de la tige pour fournir un effet d'amortissement. L’extrémité de pare-chocs présente un corps en forme de coupelle comportant une paroi latérale et une base, la paroi latérale présentant une surface interne et une surface externe, la surface interne présentant une dimension qui est dimensionnée pour être ajustée par pression sur le tube externe. La base de l’extrémité de pare-chocs comporte un trou traversant dans la base, le trou traversant étant conçu pour faire passer la tige à travers celui-ci. La base comporte au moins un passage de fluide s'étendant à l'opposé du trou traversant qui est en communication fluidique avec un réservoir de fluide dans la paroi latérale.
