Title
(DE) FEDERBEINLAGER
(EN) SPRING STRUT BEARING
(FR) PALIER DE JAMBE DE FORCE
Abstract
(DE)
Federbeinlager mit einer Kappe (2) und mit einem gegenüber der Kappe (2) um eine Drehachse (P) drehbar gelagerten Führungsring (3), wobei zwischen der Kappe (2) und dem Führungsring (3) ein Axiallager (4) angeordnet ist und wobei die Kappe (2) eine erste Dichtung (7) und eine zweite Dichtung (8) aufweist und wobei die erste Dichtung (7) schleifend an dem Führungsring (3) anliegt und die zweite Dichtung (8) als Labyrinthdichtung (13) ausgebildet ist. Die Labyrinthdichtung (13) Ist mittels ineinandergreifender Borde ausgebildet und mindestens ein Bord (14) der Kappe (2) und mindestens ein Bord (16, 17) dem Führungsring (3) zugeordnet ist, wobei die Kappe (2) aus einer Hartkomponente (20) ausgebildet ist und wobei der der Kappe (2) zugeordnete Bord (14) aus einer ersten Weichkomponente (19) ausgebildet Ist
(EN)
A spring strut bearing having a cap (2) and having a guide ring (3) rotatably mounted opposite the cap (2) and about an axis of rotation (P), wherein a thrust bearing (4) is arranged between the cap (2) and the guide ring (3), wherein the cap (2) comprises a first seal (7) and a second seal (8) and wherein the first seal (7) sits with slip against the guide ring (3) and the second seal (8) is designed as a labyrinth seal (13). The labyrinth seal (13) is designed to have interlocking flanges and at least one flange (14) is assigned to the cap (2) and at least one flange (16, 17) is assigned to the guide ring (3), wherein the cap (2) is made from a hard component (20) and wherein the flange (14) assigned to the cap (2) is made from a first soft component (19).
(FR)
L'invention concerne un palier de jambe de force, comprenant une calotte (2), et une bague de guidage (3), montée tournante autour d'un axe de rotation (P), vis-à-vis de la calotte (2), un palier axial (4) étant disposé entre la calotte (2) et la bague de guidage (3), la calotte (2) présentant un premier joint (7) et un second joint (8), le premier joint (7) s'appliquant de manière adhésive à la bague de guidage (3), et le second joint (8) étant réalisé sous la forme d'un joint labyrinthe (13). Le joint labyrinthe (13) est configuré au moyen d'un rebord assemblé par grippage, et au moins un rebord (14) étant associé à la calotte (2), et au moins un rebord (16, 17) étant associé à la bague de guidage (3), la calotte (2) étant constitué par un composant dur (20), et le rebord (14) associé à la calotte (2) étant constitué par un premier composant mou (19).
