The invention relates to a hybrid electric driving device which comprises an engine, a first motor, a second motor, a speed change mechanism, a first input shaft, a second input shaft, a third input shaft, an intermediate shaft, an output shaft, a rear transmission gear set, a first gear gear set, a second gear gear set and a third gear gear set. The first motor is connected to the first input shaft. The second motor is connected with the second input shaft, and the engine is connected with the third input shaft. By the adoption of the hybrid electric driving device, when a vehicle runs at a medium-low speed, a related gear meshed with the third input shaft is not dragged, when the vehicle runs at a medium-high speed, a related gear meshed with the first motor and the first input shaft is not dragged, internal dragging loss is reduced, and the energy efficiency of an electric driving system is improved. When the high-voltage electrical system breaks down, a neutral gear can be engaged through a first gear shifting element and a second gear shifting element, so that the first motor and the second motor are not dragged by the engine, the engine independently drives the vehicle to complete crippling home, the functions are complete, and the energy efficiency 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、变速机构、第一输入轴、第二输入轴、第三输入轴、中间轴、输出轴、后传动齿轮组、第一挡位齿轮组、第二挡位齿轮组、第三挡位齿轮组,第一电机与第一输入轴相连,第二电机与第二输入轴相连,发动机与第三输入轴相连。采用了本发明的混合电驱动装置,车辆中低速行驶时,与第三输入轴啮合相关齿轮不被拖动,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,降低内部的拖曳损失,提高电驱动系统能效。在高压电气系统出现故障时可通过第一换挡元件和第二换挡元件挂空挡使第一电机和第二电机不被发动机拖动,发动机单独驱动车辆完成跛足回家,从而功能完整且提升能效。
