Abstract

Titre : Jambe de force d’un système de suspension de véhicule automobile Jambe de force (1) d’un système de suspension de véhicule automobile comportant au moins un amortisseur (2) avec un cylindre d’amortisseur (4) et une tige (6) coulissante dans le cylindre et dont l’extrémité libre (10) coopère avec un bloc filtrant (24), le bloc filtrant (24) comportant un corps rigide formant une cage de réception pour cartouche de filtration (36) liée à l’extrémité libre (10) de la tige d’amortisseur (6), le bloc filtrant (24) comprenant une première extrémité (44) et une deuxième extrémité (46) formant chacune des parois opposées du logement interne, la deuxième extrémité (46) étant plus proche du cylindre d’amortisseur (4) que la première extrémité (44), caractérisé en ce que la première extrémité (44) comprend une paroi de renvoi (50) issue de matière du corps rigide et formant une butée au déplacement axial de la cartouche de filtration (36) et en ce que la deuxième extrémité (46) est fermée par un élément de retenue (51) rapporté et fixé sur le corps rigide (38) du bloc filtrant (24). (Figure 3)Title: Strut of a motor vehicle suspension system Strut (1) of a motor vehicle suspension system comprising at least one shock absorber (2) with a shock absorber cylinder (4) and a rod ( 6) sliding in the cylinder and whose free end (10) cooperates with a filter block (24), the filter block (24) comprising a rigid body forming a receiving cage for filtration cartridge (36) linked to the free end (10) of the shock absorber rod (6), the filter block (24) comprising a first end (44) and a second end (46) each forming opposite walls of the internal housing, the second end (46) being closer to the shock absorber cylinder (4) than the first end (44), characterized in that the first end (44) comprises a return wall (50) made from material of the rigid body and forming a stop to axial movement of the filtration cartridge (36) and in that the second end (46) is closed by a retaining element (51) attached and fixed to the rigid body (38) of the filter block (24).
