Abstract | A sensor device (20) for detecting whether a tractor and a trailer (14) of a truck (10) are connected includes a container having a plurality of tabs (26) extending radially outwardly to engage an inside surface of a bearing plate (62) of the trailer (14) when the container is located in a hole (80) in the bearing plate (62). A spring (24) extends from a base of the container away from the face surface to bear upon an interior wall of the trailer to bias the tabs into contact with the inside wall when the container is located in the hole to maintain a position of the container therein. A sensor (60) is also provided for sensing proximity of a ferrous material and being located in the container. The sensor (60) senses proximity of ferrous material of a coupler carried by the tractor without sensing ferrous material of the bearing plate (62).
La présente invention concerne un dispositif capteur (20) permettant de détecter si un tracteur et une remorque (14) de camion (10) sont connectés, qui comprend un récipient possédant une pluralité de languette (26) s'étendant radialement vers l'extérieur pour entrer en contact avec la surface intérieure d'une plaque de base (62) de la remorque (14) lorsque le récipient est situé dans un trou (80) de cette plaque de base (62). Un ressort (24) s'étend à partir d'une base du récipient à distance de la surface de face afin de porter sur une paroi intérieure de la remorque et presser les languettes en contact avec la paroi intérieure lorsque le récipient est situé dans le trou afin de maintenir une position de ce récipient à l'intérieur de celui-ci. Un capteur (60) permet aussi de capter la proximité d'un matériau ferreux et est situé dans le récipient. Ce capteur (60) détecter la proximité d'un matériau ferreux d'un coupleur porté par le tracteur sans capter le matériau ferreux de la plaque de base (62). |
