The invention relates to the technical field of hybrid power vehicles, in particular to a dual-motor hybrid drive system and a vehicle. According to the dual-motor hybrid drive system, an intermediate shaft is provided with a first gear switching piece and a second gear switching piece which can be connected or disconnected with part of gears in a first gear set; the engine is connected with the input shaft, and the input shaft is provided with a third gear switching piece and a fourth gear switching piece which can be connected with or disconnected from part of gears in the second gear set. The first motor is provided with a first motor shaft in transmission connection with the input shaft; the second motor is provided with a second motor shaft in transmission connection with the intermediate shaft; the front drive axle assembly is provided with a front output shaft in transmission connection with the intermediate shaft. Different working modes are formed by controlling the connection or disconnection state of the first gear switching piece, the second gear switching piece, the third gear switching piece and the fourth gear switching piece and cooperation of the power sources, and multi-gear output can be achieved in the different working modes, so that oil consumption of the vehicle is effectively reduced.
本发明涉及混合动力车辆技术领域,尤其是涉及一种双电机混合驱动系统及车辆。双电机混合驱动系统包括:中间轴设置有能够与第一齿轮组中的部分齿轮接合或断开的第一挡位切换件和第二挡位切换件;发动机与输入轴连接,输入轴上设置有能够与第二齿轮组中的部分齿轮接合或断开的第三挡位切换件和第四挡位切换件;第一电机具有与输入轴传动连接的第一电机轴;第二电机具有与中间轴传动连接的第二电机轴;前驱动桥总成具有与中间轴传动连接的前输出轴。本发明通过控制第一挡位切换件、第二挡位切换件、第三挡位切换件和第四挡位切换件的接合或断开状态以及动力源的协同,形成不同的工作模式,且不同的工作模式可以多挡位输出,从而有效降低车辆的油耗。
