Title
(EN) WEAR INDICATOR DEVICE FOR THE BRAKE PADS OF A MOTOR VEHICLE
(FR) DISPOSITIF AVERTISSEUR D"USURE DE GARNITURE DE FREIN POUR VEHICULE AUTOMOBILE
Abstract
(EN)
The device comprises a plurality of detection circuits (11A, 11B, 11C), mounted in parallel for the control of the supply circuit of a general indicating member (10), and comprising each an orientation diode (29A, 29B, 29C) to avoid the looping thereof on another one, such an orientation diode is an electroluminescent diode so that it forms by itself an individual indicating member (29A, 29B, 29C) associated to said detection circuit. The device comprises means (14) to indicate a possible mounting error, means (47, 48, 51, 52, 53) for adjusting the intensity of the indicator (10) in relation to the condition of the lighting members (50) of the vehicle and an automatic test circuit (34).
(FR)
Le dispositif comporte plusieurs circuits de detection (11A, 11B, 11C), montes en parallele pour le controle du circuit d"alimentation d"un organe d"avertissement general (10), et comportant chacun une diode d"orientation (29A, 29B, 29C) pour eviter son bouclage sur un autre, une telle diode d"orientation est une diode electroluminescente, en sorte qu"elle constitue par elle-meme un organe d"avertissement individuel (29A, 29B, 29C) associe a un tel circuit de detection. Le dispositif comporte des moyens (14) pour signaler une eventuelle erreur de montage, des moyens (47, 48, 51, 52, 53) pour regler l"intensite de l"avertisseur (10) en fonction de l"etat d"organes d"eclairage (50) du vehicule et un circuit de test automatique (34).
