Speed sensor for transmission output

The invention concerns a speed sensor for transmission output comprising a Hall-effect detector (11) or a variable reluctance detector and a means (10) of producing a magnetic field. According to the invention, the means (10) is built into an axial thrust bearing positioned around a differential cas...

Zusammenfassung:	The invention concerns a speed sensor for transmission output comprising a Hall-effect detector (11) or a variable reluctance detector and a means (10) of producing a magnetic field. According to the invention, the means (10) is built into an axial thrust bearing positioned around a differential casing (5) of a motor vehicle transmission. In this way a structural modification of the transmission itself is avoided. L'invention concerne un capteur de vitesse de sortie de transmission comprenant un détecteur à effet Hall (11) ou un détecteur à réluctance variable et un moyen (10) pour produire un champ magnétique. Selon l'invention, le moyen (10) est intégré dans une butée axiale positionnée autour d'un boîtier de différentiel (5) d'une transmission d'automobile. On évite ainsi une modification structurelle de la transmission elle-même.
