Abstract
(DE)
Um eine Lagervorrichtung (200, 202, 300, 400, 500) für ein Untersetzungsgetriebe (11) für eine elektromechanische Servolenkung, umfassend ein erstes Ende (251) und ein dem ersten Ende (251) gegenüberliegendes zweites Ende (252), wobei zwischen dem ersten Ende (251) und dem zweiten Ende (252) ein Kontaktabschnitt (250) vorgesehen ist, und einen Lagerabschnitt (260) zum Lagern eines Antriebselements (13) anzugeben, bei der die Lagerung des Antriebselements (1) verbessert ist, wird vorgeschlagen, dass der Lagerabschnitt (260) als Öffnung ausgebildet ist, welche von dem ersten Ende (251) in Richtung des zweiten Endes (252) hineinragt und eine Ausnehmung (253) vom zweiten Ende (252) in Richtung des ersten Endes (251) hineinragt, wobei die Öffnung (260) zu der Ausnehmung (253) radial beabstandet ist.
(EN)
The invention relates to a bearing device (200, 202, 300, 400, 500) for a reduction gear (11) for an electromechanical power steering system, having a first end (251) and a second end (252) opposite the first end (251), a contact portion (250) being provided between the first end (251) and the second end (252), and further having a bearing portion (260) for supporting a drive element (13). The aim of the invention is to improve the support of the drive element (1) of said bearing device. This aim is achieved, according to the invention, in that the bearing portion (260) is designed as an opening which extends from the first end (251) towards the second end (252) and a recess (253) extends from the second end (252) towards the first end (251), the opening (260) being radially spaced from the recess (253).
(FR)
L'invention vise à fournir un dispositif de palier (200, 202, 300, 400, 500) pour un réducteur (11) pour une direction électromécanique assistée, comprenant une première extrémité (251) et une deuxième extrémité (252) opposée à la première extrémité (251), une partie de contact (250) étant prévue entre la première extrémité (251) et la deuxième extrémité (252), et une partie de palier (260) pour supporter un élément d'entraînement (13), dans lequel le palier de l'élément d'entraînement (1) est amélioré. À cet effet, la partie de palier (260) se présente sous forme d'ouverture qui fait saillie de la première extrémité (251) en direction de la deuxième extrémité (252) et un évidement (253) fait saillie de la deuxième extrémité (252) en direction de la première extrémité (251), l'ouverture (260) étant radialement espacée de l'évidement (253).
