Abstract

L'invention concerne un dispositif d'entraînement (1) pour une chaîne cinématique d'un véhicule à moteur comprenant un moteur à combustion interne et un moteur électrique (4) disposé coaxialement avec ce dernier, un amortisseur de vibrations de torsion (9) doté d'un dispositif à ressort (10) disposé entre le rotor (6) et l'arbre de sortie (8) de manière à être efficace dans la direction circonférentielle étant disposé entre le rotor (6) du moteur électrique (4) et l'arbre de sortie (8) du dispositif d'entraînement (1). Afin de proposer un meilleur amortissement des vibrations de torsion du dispositif d'entraînement (1) dans une plage de charge partielle du moteur à combustion interne, en tenant compte du moment d'inertie du rotor (6), un taux de torsion du dispositif à ressort (10) est réglé à une valeur inférieure ou égale à 20 Nm/°, de préférence inférieure ou égale à 10 Nm/°, de préférence particulièrement inférieure ou égale à 5 Nm/°, pour une plage d'angle de torsion prédéterminée entre le rotor (6) et l'arbre de sortie (8) inférieure à un angle de torsion maximal.
