Abstract

L'invention concerne un dispositif de démarrage pour moteurs à combustion interne, comprenant un moteur de démarreur dont le pignon vient s'engrener tout d'abord avec la couronne dentée du moteur à combustion interne, au moyen d'un signal de démarrage par l'intermédiaire d'un aimant d'engrènement, avant que le moteur de démarreur ne déploie toute son énergie pour le déclenchement du processus de démarrage. L'invention vise à améliorer l'engrènement du pignon de démarreur et la commutation du moteur de démarreur. A cet effet, le moteur de démarreur (SM) entraîne tout d'abord le pignon de démarreur avec un couple réduit au moyen du signal de démarrage (st) par l'intermédiaire d'un résistance série (Rvor), et l'aimant d'engrènement (EM) engrène le pignon avec la couronne dentée du moteur à combustion interne. Ensuite, l'aimant d'engrènement (EM) enfonce entièrement le pignon dans la couronne dentée du moteur à combustion interne, et le moteur de démarreur (SM) lance le moteur à combustion interne avec le couple total par contournement de la résistance série (Rvor).
