Title (EN) FIXED BEARING FOR A STEERING GEAR AND METHOD FOR MANUFACTURING THE FIXED BEARING
(FR) PALIER FIXE POUR UN MÉCANISME DE DIRECTION ET PROCÉDÉ POUR FABRIQUER LE PALIER FIXE
(DE) FESTLAGER FÜR EIN LENKGETRIEBE UND VERFAHREN ZUR HERSTELLUNG DES FESTLAGERS
Abstract:
(EN) A fixed bearing (6) for a steering gear comprises a rotary bearing (9) having an inner bearing ring (11) for receiving a pinion shaft (4) of the steering gear, and an outer bearing ring (12). Furthermore, the fixed bearing (6) has a pivoting ring (15) which has an outer ring (17) and an inner ring (16), which rings (17, 16) are pivotably connected via one or more torsion webs, wherein the outer ring (17) is provided for supporting the fixed bearing (15) in a housing (1) of the steering gear. Such a fixed bearing (15) is also characterized in that the inner ring (16) of the pivoting ring (15) and the outer bearing ring (12) of the rotor bearing (9) are directly connected, and in particular welded, to one another.
(FR) L'invention concerne un palier fixe (6) pour un mécanisme de direction. Le palier fixe comprend un palier rotatif (9) qui comporte une bague de palier intérieure (11) destinée à loger un arbre de pignon (4) du mécanisme de direction, et une bague de palier extérieure (12). Par ailleurs, le palier fixe (6) comprend une bague pivotante (15) qui comporte une bague extérieure (17) ainsi qu'une bague intérieure (16) reliées de manière à pouvoir pivoter par l'intermédiaire d'un ou de plusieurs éléments jointifs de torsion, la bague extérieure (17) étant destinée à servir de support au palier fixe (15) dans un carter (1) du mécanisme de direction. Ledit palier fixe (15) est caractérisé en outre par le fait que la bague intérieure (16) de la bague pivotante (15) et la bague de palier extérieure (12) du palier rotatif (9) sont reliées directement l'une à l'autre et sont en particulier soudées l'une à l'autre.
(DE) Ein Festlager (6) für ein Lenkgetriebe umfasst ein Drehlager (9), das einen inneren Lagerring (11), der zur Aufnahme einer Ritzelwelle (4) des Lenkgetriebes vorgesehen ist, und einen äußeren Lagerring (12) aufweist. Weiterhin umfasst das Festlager (6) einen Schwenkring (15), der einen Außenring (17) sowie einen Innenring (16) aufweist, die über einen oder mehrere Torsionsstege verschwenkbar verbunden sind, wobei der Außenring (17) zur Lagerung des Festlagers (15) in einem Gehäuse (1) des Lenkgetriebes vorgesehen ist. Ein solches Festlager (15) ist weiterhin dadurch gekennzeichnet, dass der Innenring (16) des Schwenkrings (15) und der äußere Lagerring (12) des Drehlagers (9) direkt miteinander verbunden und insbesondere verschweißt sind.
