Abstract

L'invention concerne un dispositif capteur de charge (52) servant à mesurer des charges de contact de roue appliquées sur un système de suspension (10) du véhicule. Le capteur de charge (52) selon l'invention comprend un élément souple (74) raccordé fonctionnel au système de suspension (10) et à un logement (72). Une carte de circuits imprimés (78) est fixée au système de suspension (10) et au logement (72), des capteurs (92) étant fixés sur ladite carte (78). Ces capteurs (92) mesurent les mouvements de la carte (78) créés en réponse aux charges de roue appliquées par l'élément souple (74).
