Title
(EN) SMART BOLT DEVICE HAVING COMMUNICATIONS SYSTEM IN SEPARATE HOUSING FROM BOLT
(FR) DISPOSITIF A BOULON INTELLIGENT DOTE D'UN SYSTEME DE COMMUNICATIONS SITUE DANS UN BOITIER SEPARE
Abstract
(EN)
A hot bearing detection system as shown which spatially separates the thermal sensor (21) which is disposed within a bearing-securing bolt (10) from the communication means (42) for communicating high temperature conditions occuring at a railroad car bearing or the like. The housing (22) for the communication means is disposed adjacent the bearing and is connected electrically with the thermal sensor such that when high temperature conditions occur the conditions will be r.f.-communicated to the wayside or to a locomotive.
(FR)
L'invention concerne un système de détection de coussinet à température élevée, représenté dans la figure 1, qui maintient espacés le capteur thermique (21) placé dans un boulon de fixation de coussinet (10) et le moyen de communications (42) conçu pour signaler les conditions de haute température survenant au niveau d'un coussinet de voiture de chemin de fer ou similaire. Le boîtier (22) pour le moyen de communication est placé à proximité du coussinet et est connecté électriquement au capteur thermique de sorte que toute apparition de conditions de haute température soit signalée par ondes radioélectriques au côté de la voie ou à la locomotive.
