Abstract

L'invention concerne une structure de fixation pour un embrayage électromagnétique. Lorsqu'un boîtier de réception de bobine recevant une bobine d'excitation de l'embrayage électromagnétique est fixé à une position d'installation prédéterminée avec une plaque d'installation placée entre eux, la résistance de liaison entre le boîtier de réception de bobine et la plaque d'installation est accrue et la vibration du boîtier de réception de bobine est réduite. L'embrayage électromagnétique (1) inclue une bobine d'excitation (2) qui amène la surface de friction (15) d'une armature (4) à être attirée vers une surface de friction (13) d'un rotor (3). Ledit embrayage électromagnétique (1) comporte également un boîtier de réception de bobine (6) de forme annulaire pour recevoir la bobine d'excitation (2). Une feuille (30) est interposée entre le boîtier de réception de bobine (6) et la plaque d'installation (8) pour fixer le boîtier de réception de bobine (6) à la position d'installation prédéterminée sur la plaque d'installation (8).
