Abstract

Eine Liftzylindereinheit (1) weist ein ortsfestes Stangenrohr (2) mit einer Längsachse (3) auf, das in einem seiner axialen Endbereiche mit einem Stangenkopf (4) fest verbunden ist. Außerhalb des Stangenrohrs (2) ist ein Zylinderrohr (14) so angeordnet, daß es entlang der Längsachse (3) relativ zu dem Stangenrohr (2) verschieblich ist. In einem der axialen Endbereiche des Zylinderrohrs (14) ist ein Zylinderboden (15) vorgesehen, der fest mit dem Zylinderrohr (14) verbunden ist. Eine eine Kraftangriffsfläche (30) aufweisende Führungsbuchse (18) ist mit der äußeren Oberfläche (22) des Zylinderrohrs (14) fest verbunden. Innerhalb des Stangenrohrs (2) ist ein Druckraum (31) angeordnet, der über eine Anschlußbohrung (7) mit einem Hydraulikmedium versorgt und über eine dynamische Dichtung (24) und eine Lauffläche (25) gegenüber der Umgebung abgedichtet ist. Die Liftzylindereinheit (1) ist in Plungerbauweise ausgebildet. Die dynamische Dichtung (24) ist im Bereich der inneren Oberfläche (23) der Führungsbuchse (18) angeordnet. Die Lauffläche (25) für die dynamische Dichtung (24) ist im Bereich der äußeren Oberfläche (26) des Stangenrohrs (2) angeordnet.
