Title
(DE) LENKSYSTEM MIT SCHWENKLAGER
(EN) STEERING SYSTEM WITH PIVOT BEARING
(FR) SYSTÈME DE DIRECTION AVEC PALIER DE PIVOTEMENT
Abstract
(DE)
Die Erfindung betrifft ein Lenksystem für ein Kraftfahrzeug (1) mit einem Schneckengetriebe (2), umfassend ein Schneckenrad (3) und eine Schneckenwelle (4), wobei die Schneckenwelle (4) an mindestens einer Lagerstelle (5) mittels eines Schwenklagers (6) in einem Gehäuse des Schneckengetriebes (2) drehbar gelagert ist. Es ist vorgesehen, dass das Schwenklager (6) im Vergleich zu einem Schwenklager mit einem einreihigen Standardrillenkugellager eine erhöhte Tragkraft aufweist. Die Erfindung betrifft ferner ein Schwenklager (6) für ein Lenksystem (1) mit einem Innenring (11) und einem Außenring (12), wobei zwischen dem Innenring (11) und dem Außenring (12) eine Mehrzahl von Wälzkörpern (17) angeordnet ist. Es ist vorgesehen, dass einer der Lagerringe (11, 12) als Vollring und der jeweils andere Lagerring (11, 12) als geteilter Lagerring (21) ausgeführt ist, wobei der geteilte Lagerring (21) ein erstes Ringelement (22) und ein zweites Ringelement (23) aufweist.
(EN)
The invention relates to a steering system for a motor vehicle (1) having a worm gear set (2), comprising a worm wheel (3) and a worm screw (4), the worm screw (4) being mounted rotatably in a housing of the worm gear set (2) by means of a pivot bearing (6) at at least one bearing point (5). According to the invention, the pivot bearing (6) has a higher load capacity than a pivot bearing with a single-row standard grooved ball bearing. The invention further relates to a pivot bearing (6) for a steering system (1), having an inner race (11) and an outer race (12), a plurality of rolling elements (17) being arranged between the inner race (11) and the outer race (12). According to the invention, one of the bearing races (11, 12) is designed as a solid race and the respective other bearing race (11, 12) is designed as a split bearing race (21), wherein the split bearing race (21) comprises a first race element (22) and a second race element (23).
(FR)
L'invention concerne un système de direction pour un véhicule automobile (1) pourvu d'un engrenage à vis sans fin (2), comprenant une roue à vis sans fin (3) ainsi qu'un arbre à vis sans fin (4) qui est monté à rotation au niveau d'au moins un point d'appui (5) au moyen d'un palier de pivotement (6) dans un carter de l'engrenage à vis sans fin (2). Selon l'invention, le palier de pivotement (6) possède une force portante accrue par rapport à un palier de pivotement avec un roulement à billes à gorge profonde standard à une rangée. L'invention concerne en outre un palier de pivotement (6) pour un système de direction (1), comprenant une bague intérieure (11) et une bague extérieure (12), une pluralité d'éléments de roulement (17) étant disposés entre la bague intérieure (11) et la bague extérieure (12). Selon l'invention, l'une des bagues de roulement (11, 12) est réalisée sous la forme d'une bague pleine et l'autre bague de roulement (11, 12) respective est réalisée sous la forme d'une bague de roulement fendue (21). La bague de roulement fendue (21) possède un premier élément de bague (22) et un deuxième élément de bague (23).
