Abstract

Dans le mécanisme d'entraînement à deux étages (40) pour les auxiliaires d'un véhicule à moteur, un moteur entraîne de manière constante un rotor d'entraînement (3) dans le mécanisme d'entraînement (40). Le rotor entraîne sélectivement la roue solaire (7) d'un engrenage planétaire faux (9), soit au moyen d'un premier embrayage à friction électromagnétique (1), d'une couronne (4) et des première et deuxième roues planétaires fausses (5, 6), soit au moyen d'un deuxième embrayage à friction électromagnétique (2) et d'un rotor intermédiaire (36). La roue solaire (7) entraîne le rotor (8) de l'auxiliaire, p.ex. l'arbre d'entraînement d'un compresseur dans un système d'air conditionné. Dans un troisième mode de fonctionnement, les deux embrayages à friction (1, 2) peuvent rester ouverts. Dans ce cas, le moteur entraîne uniquement le rotor d'entraînement (3). Le rotor d'entraînement (3) peut former une poulie à courroie pour une courroie trapézoïdale multiple. Les embrayages à friction (1, 2) peuvent être des embrayages à sec.
