The invention relates to a hybrid electric driving device which comprises an engine, a first motor, a second motor and a speed change mechanism, the first motor is connected with a first intermediate shaft, the second motor is connected with a second intermediate shaft, the engine is connected with an input shaft, the input shaft is connected with a third intermediate shaft through a front transmission gear set, and the engine is connected with the input shaft through a main clutch. By the adoption of the hybrid electric driving device, the engine can utilize all gears, the first motor and the second motor can only utilize part of the gears, when the vehicle runs at a medium-low speed, relevant gears meshed with the third input shaft are not dragged at the moment, and when the vehicle runs at a medium-high speed, the first motor and the first input shaft are engaged with related gears and are not dragged, so that the internal dragging loss during vehicle running is reduced, and the energy efficiency of the electric driving system is improved.

    本发明涉及一种混合电驱动装置,包括发动机、第一电机、第二电机和变速机构,所述的第一电机与第一中间轴连接,所述的第二电机与第二中间轴连接,所述的发动机与输入轴连接,所述的输入轴通过前传动齿轮组与第三中间轴连接,所述的发动机通过主离合器与输入轴连接。采用了本发明的混合电驱动装置,发动机可以利用全部的挡位而第一电机和第二电机只能利用部分的挡位,在车辆中低速行驶时,此时与第三输入轴啮合相关齿轮不被拖动,当车辆中高速行驶时,第一电机和第一输入轴啮合相关齿轮不被拖动,降低车辆行驶时内部的拖曳损失,提高电驱动系统能效。
