Description
technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, and relates to a drive assembly for a hybrid electric vehicle, in particular to a multi-mode coupling drive system with multiple power sources. Background technique [0002] The existing hybrid drive system based on the power split power coupling mechanism, in the EVT mode, if only the input split mode is used, it is only suitable for low-speed driving conditions, and the efficiency of high-speed conditions decreases, and due to the motor, it cannot be used for a long time. Keep up the speed. Therefore, most hybrid drive systems use a combination of input split and compound split modes, so that the power split mode can adapt to high and low speed conditions at the same time. However, the power coupling mechanism of this drive system requires two to three planetary gear mechanisms, and requires more clutches and brakes, resulting in a complex structure of the drive system, increa...
