Abstract
(DE)
Die Erfindung betrifft eine Lagerbuchse (10), insbesondere für Kraftfahrzeuge, mit einem Innenrohr (11) und einem Außenrohr (12) sowie einem zwischen Innenrohr (11) und Außenrohr (12) angeordneten Tragkörper (13) aus elastomerem Material. Der Tragkörper (13) weist in Radialrichtung verlaufende, rippenförmige Stege (18) auf. Um in den verschiedenen Belastungsrichtungen ein unterschiedliches Steifigkeitsverhältnis zu erzielen, weisen zwischen den Stegen (18) vorgesehene stollenförmige, elastische Anschläge (19b, 20b) Hinterfütterungsbereiche (16) auf, die am Außenrohr (12) ausgebildet sind.
(EN)
The invention concerns a bearing bush (10), in particular for motor vehicles, the bearing bush comprising an inner pipe (11), an outer pipe (12) and an elastomer carrier member (13) disposed between the latter. The carrier member (13) comprises rib-like webs (18) extending in the radial direction. In order to attain a different rigidity ratio in the various load directions, resilient stud-like stops (19b, 20b) provided between the webs (18) comprise rear lining regions (16) which are formed on the outer pipe (12).
(FR)
L'invention concerne un coussinet (10), notamment pour automobiles, qui comprend un tube intérieur (11) et un tube extérieur (12), ainsi qu'un élément support (13) en matériau élastomère monté entre le tube intérieur (11) et le tube extérieur (12). L'élément support (13) présente des entretoises (18) sous forme d'ailettes qui s'étendent dans le sens radial. Afin de parvenir à un rapport de rigidité différent dans les différentes directions de charge, des butées (19b, 20b) élastiques sous forme de patins présentent des zones de revêtement arrière (16) formées sur le tube extérieur (12).
