Abstract
Pour empêcher les corps étrangers tels que l'eau, la boue, le sable, les graviers et les petits cailloux, de pénétrer dans les roulements des branches du croisillon on utilise un joint comprenant une bague (5) à profil en L, qui est bloquée dans la douille (4) et qui retient et donne appui à une garniture (6) présentant plusieurs lèvres (7, 8, 9) qui s'appuient contre la base conique ou profilée du tourillon (2).To prevent foreign bodies such as water, mud, sand, gravel and small pebbles from entering the bearings of the arms of the spider, a seal is used comprising a ring (5) with an L-profile, which is blocked in the sleeve (4) and which retains and gives support to a lining (6) having several lips (7, 8, 9) which bear against the conical or profiled base of the journal (2).
