Abstract

L'invention concerne la mesure du pincement des roues d'un véhicule. Elle se rapporte à un appareil dans lequel un projecteur 12 fixé à la roue dont le pincement doit être déterminé contient, à demeure, un arrangement de sources lumineuses, par exemple un arrangement de photodiodes 1L, 2L, 3L, 4L, 5L, projetant des faisceaux lumineux suivant un dessin divergent. Un faisceau B de référence vient frapper un détecteur 16 lorsque le pincement est nul, et le pincement est déterminé d'arpès l'angle formé par le faisceau B' qui vient frapper le détecteur 16 avec le faisceau B de référence. Application à la mesure du pincement des roues des véhicules.
