Abstract

L'invention concerne un palier de colonne de direction (1), conçu sous la forme d'un roulement à billes à contact oblique, pour le montage d'un arbre de direction (2) d'un véhicule automobile, constitué d'une bague de palier interne (4) et d'une bague de palier externe (5), entre lesquelles des éléments de roulement (7), qui sont répartis sur la circonférence, sont guidés sur des chemins de roulement associés (8, 9) : le palier de colonne de direction (1) étant fixé contre un décalage axial au moyen d'une unité de montage (10) positionnée sur l'arbre de direction (2), laquelle unité de montage (10) présentant une fonction de ressort, une fonction de serrage et une fonction de retenue ; l'unité de montage (10), qui atteint une courbe caractéristique de ressort progressive ou régressive, comprend des segments de type dent (13) orientés axialement et venant en prise entre la bague de palier interne (4) et l'arbre de direction (2), et des griffes (14) qui sont réparties de manière circonférentielle et verrouillées par force et/ou par friction sur l'arbre de direction (2).
