A method and apparatus for measuring the wheel alignment of a vehicle on a production line. In the measuring method, a wheel hub (55) having a plurality of hub bolts (56) for mounting a wheel to is rotated while displacements of the hub bolts are measured with displacement measuring sensors (73, 74). The wheel alignment is measured by calculating an angle of inclination (0) of the wheel hub on the basis of the measured displacements of the hub bolts.

L'invention concerne un procédé et un appareil permettant de mesurer l'alignement des roues d'un véhicule sur une chaîne de production. Lors du procédé de mesure, un moyeu (55) de roue, muni de plusieurs boulons (56) de moyeu destinés au montage d'une roue, tourne tandis que l'on mesure les déplacements desdits boulons au moyen de capteurs (73, 74) de mesures de déplacement. On mesure l'alignement des roues en calculant un angle d'inclinaison (.theta.) du moyeu de roue en fonction des déplacements des boulons de moyeu que l'on a mesurés.
