Title
(EN) HYBRID POWER DRIVE SYSTEM AND DRIVE METHOD THEREOF
(FR) SYSTÈME D’ENTRAÎNEMENT À ÉNERGIE HYBRIDE ET PROCÉDÉ D’ENTRAÎNEMENT ASSOCIÉ
Abstract
(EN) A hybrid power drive system comprises an engine (10), a first motor (30), a first clutch(20) operatively coupled between the engine (10) and the first motor (30); a first decelerating mechanism (50) which has an input portion and an output portion,wherein the input portion operatively couples between the first clutch (20) and the first motor (30) and configures to receive rotational power from the first motor (30) and /or the engine (10), and the output portion operatively drives at least one first wheel (30); a second motor (70) operatively coupled to at least one second wheel (90) via a second decelerating mechanism (80); and an energy storage device (100) electrically coupled to the first motor (30) and the second motor (70) respectively, for storing or supplying energy to the first motor (30) and second motor (70) respectively. A plurality of operating modes is provided to meet energy efficiency requirements.
(FR) L’invention porte sur un système d’entraînement à énergie hybride comprenant un moteur (10), un premier moteur (30), un premier embrayage (20) couplé de manière opérationnelle entre le moteur (10) et le premier moteur (30) ; un premier mécanisme de décélération (50) possédant une partie d’entrée et une partie de sortie, la partie d’entrée étant couplée de manière opérationnelle entre le premier embrayage (20) et le premier moteur (30) et configurée pour recevoir l’énergie de rotation provenant du premier moteur (30) et/ou du moteur (10), et la partie de sortie entraînant de manière opérationnelle au moins une première roue (30) ; un second moteur (70) couplé de manière opérationnelle à au moins une seconde roue (90) via un second mécanisme de décélération (80) ; et un dispositif de stockage d’énergie (100) électriquement couplé respectivement au premier moteur (30) et au second moteur (70), servant à stocker l’énergie ou à l’amener au premier moteur (30) et au second moteur (70) respectivement. Une pluralité de modes de fonctionnement permet de satisfaire aux exigences en matière de rendement énergétique.
