Abstract
(DE)
Die Erfindung betrifft eine Radlagereinheit (1) eines Fahrzeugs, insbesondere eines landwirtschaftlichen Fahrzeugs, umfassend eine Nabe (2) zur Anbringung eines Rades (3) des Fahrzeugs, wobei die Nabe (2) mittels mindestens eines Lagers (4) in einem Gehäuse (5) gelagert ist, wobei Mittel (6, 7) zur Erfassung einer vom Rad (3) auf das Gehäuse (5) übertragenen Kraft vorhanden sind. Um in einfacher Weise die effektiv wirksamen Kräfte vom Boden auf das Gehäuse messen zu können, sieht die Erfindung vor, dass die Mittel (6, 7) einen Messring (6) umfassen, der an einem der Ringe (8) des Lagers (4) angeordnet ist und sich über die axiale Erstreckung des Rings (8) hinaus erstreckt und mit einem Endbereich mit dem Gehäuse (5) verbunden ist, wobei in einem axialen Abschnitt (9) des Messrings (6), der zwischen dem Ring (8) des Lagers (4) und der Verbindungsstelle (10) mit dem Gehäuse (5) liegt, ein Messmittel (7) zur Erfassung der mechanischen Spannung angeordnet ist.
(EN)
The invention relates to a wheel bearing unit (1) of a vehicle, in particular of an agricultural vehicle, comprising a hub (2) for attaching a wheel (3) of the vehicle, said hub (2) being mounted in a housing (5) by means of at least one bearing (4), and means (6, 7) being provided for sensing a force transferred from the wheel (3) to the housing (5). In order to easily measure the forces from the ground that are actually acting on the housing, according to the invention the means (6, 7) comprise a ring gauge (6) which is disposed on one of the rings (8) of the bearing (4), extends over the axial extent of the ring (8) and is connected to the housing (5) by an end region, and a measuring device (7) for sensing mechanical stress is provided in an axial section (9) of the ring gauge (6), said section being positioned between the ring (8) of the bearing (4) and the connection point (10) to the housing (5).

L’invention concerne une unité de palier de roue (1) d’un véhicule, en particulier d’un véhicule agricole, comprenant un moyeu (2) pour le montage d’une roue (3) du véhicule, le moyeu (2) étant logé dans un carter (5) au moyen d’au moins un palier (4), des moyens (6, 7) pour la détection d’une force transmise de la roue (3) au carter (5) étant prévus. Selon l’invention, pour pouvoir mesurer de manière simple les forces agissant du sol sur le carter, les moyens (6, 7) comprennent un anneau de mesure (6), lequel est disposé sur un des anneaux (8) du palier (4) et s'étend au-delà de l’extension axiale de l’anneau (8) et est connecté par une zone d'extrémité au carter (5), un instrument de mesure (7) pour la détection de la tension mécanique étant disposé dans une partie axiale (9) de l’anneau de mesure (6) située entre l’anneau (8) du palier (4) et le point de liaison (10) avec le carter (5).
