Abstract

L'invention concerne un embrayage destiné à accoupler deux arbres coaxiaux rotatifs. L'invention est remarquable par le fait qu'un premier arbre est solidaire en rotation d'un inducteur à aimants permanents mobile en translation, suivant l'axe desdits arbres, dans une enceinte formée par deux armatures et intérieurement revêtue d'une couche en matériau magnétique disposée de manière que le flux magnétique traversant l'inducteur soit constant, l'une des deux armatures étant solidaire en rotation du deuxième arbre. L'embrayage de l'invention ne requiert qu'une faible énergie de commande et est sans usure.
