Patent

CA 2378214

In an engine-starting and stopping system in a vehicle, a crank pulley for driving auxiliary parts by an endless belt is mounted at an end of a crankshaft protruding from a cylinder block of an engine, and a starter motor for cranking the crankshaft is accommodated in an internal space in the crank pulley. The starter motor includes a rotor having a permanent magnet fixed to an inner peripheral surface of a peripheral wall of the crank pulley, and a stator having a coil fixed to an outer surface of a chain cover. Thus, the starter motor for automatically carrying out the restarting of the engine after stopping of the engine can be laid out compactly.

L'invention concerne un dispositif de démarrage/arrêt d'un moteur de véhicule dans lequel une poulie du vilebrequin permet de commander une machine auxiliaire à travers une courroie sans fin installée à l'extrémité d'un arbre à vilebrequin s'étendant d'un bloc moteur et un moteur de démarreur permet de démarrer l'arbre à vilebrequin logé dans l'espace intérieur de la poulie du vilebrequin. Le moteur du démarreur comprend un rotor présentant des aimants permanents fixés sur la surface périphérique interne de la paroi périphérique de la poulie du vilebrequin et un stator comprenant des bobines fixées sur la surface extérieure d'un garde-chaîne. Le moteur du démarreur, servant à relancer automatiquement le moteur une fois ce dernier est arrêté, peut être assemblé de manière compacte.
