Title
(DE) RADNABEN-RADACHSEN-ANORDNUNG ZUR LAGERUNG EINES FAHRZEUGRADES

(FR) ENSEMBLE MOYEU-ESSIEU POUR MONTER UNE ROUE DE VÉHICULE
Abstract
(DE) Die Erfindung betrifft eine Radnaben-Radachsen-Anordnung (10) mit einer Radachse, einer Radnabe (12) zur Lagerung eines Fahrzeugrades an der Radachse und einer Wälzlagereinheit (14) mit Wälzlagern (16, 18) zur Lagerung der Radnabe (12) auf einem Achszapfen (20) der Radachse. Es ist vorgesehen, dass die Radnaben- Radachsen-Anordnung (10) weiterhin eine Messanordnung (24) zur Bestimmung der Lage der Radnabe (12) relativ zur Radachse mittels einer Abstandsmessung zwischen einer Struktur (26) der Radnabe (12) einerseits und einer Achskomponente der Radachse, insbesondere dem Achszapfen (20), andererseits aufweist. Die Erfindung betrifft weiterhin eine Verwendung einer derartigen Radnaben-Radachsen-Anordnung (10) zur Ermittlung von Daten über auftretende Radkräfte eines Fahrzeugrades beim Fahren, insbesondere bei einem autonomen Fahren, mittels einer Abstandsmessung.
(EN) The invention relates to a wheel hub-wheel axle arrangement (10) comprising a wheel axle, a wheel hub (12) for mounting a vehicle wheel on the wheel axle, and a rolling bearing unit (14) having rolling bearings (16, 18) for mounting the wheel hub (12) on an axle journal (20) of the wheel axle. According to the invention, the wheel hub-wheel axle arrangement (10) also comprises a measurement arrangement (24) for determining the position of the wheel hub (12) relative to the wheel axle by measuring the distance between a structure (26) of the wheel hub (12) on the one hand and an axle component of the wheel axle, in particular the axle journal (20), on the other hand. The invention also relates to a use of such a wheel hub-wheel axle arrangement (10) for obtaining data about vehicle wheel forces occurring during driving, in particular during autonomous driving, by means of a distance measurement.
(FR) L'invention concerne un ensemble moyeu-essieu (10) comprenant un essieu, un moyeu (12) pour monter une roue de véhicule sur un essieu et un ensemble roulement (14) comprenant des roulements (16, 18) pour monter le moyeu (12) sur une fusée d'essieu (20) de l'essieu. Selon l'invention, l'ensemble moyeu-essieu (10) comprend en outre un système de mesure (24) pour déterminer la position du moyeu (12) par rapport à l'essieu par mesure de la distance entre la structure (26) du moyeu (12) d'un côté, et un composant de l'essieu, en particulier la fusée d'essieu (20), de l'autre côté. Cette invention concerne en outre l'utilisation d'un tel ensemble moyeu-essieu (10) pour déterminer des données relatives à des forces appliquées sur une roue de véhicule lors de la conduite, en particulier lors d'une conduite autonome, au moyen d'une mesure de distance.
