The invention relates to the technical field of hybrid power vehicles, in particular to a multi-gear electromechanical hybrid power system and a vehicle. A multi-stage electromechanical hybrid system includes: an engine having an engine shaft; the generator is provided with a generator shaft, the generator shaft is provided with a first gear switching piece, the input shaft and the engine shaft are coaxially arranged, the input shaft is provided with a second gear switching piece, and the intermediate shaft is provided with a third gear switching piece; three-gear adjustment is achieved by controlling the first gear switching piece, the second gear switching piece and the third gear switching piece to be in different connection or disconnection states. The braking piece and the fourth gear switching piece can be connected with or disconnected from the planet row mechanism so as to realize two-gear adjustment; the output shaft is connected with the planet row mechanism, and the driving motor can transmit power to the output shaft. The combination of the second assembly and the third assembly can realize six-gear adjustment, and has the advantages of multiple gears, simple structure, and realization of high dynamic property and high fuel economy of the whole vehicle.

    本发明涉及混合动力车辆技术领域,尤其是涉及一种多挡位机电混合动力系统及车辆。多挡位机电混合动力系统包括:发动机具有发动机轴;发电机具有发电机轴,发电机轴上设置有第一挡位切换件,输入轴与发动机轴同轴设置且输入轴上设置有第二挡位切换件,中间轴上设置有第三挡位切换件;通过控制第一挡位切换件、第二挡位切换件和第三挡位切换件处于不同的接合或断开的状态以实现三挡位调节;制动件和第四挡位切换件能够分别与行星排机构接合或断开以实现两挡位调节;输出轴与行星排机构连接,驱动电机能够将动力传递至输出轴。本发明第二组件和第三组件组合能够实现六个挡位调节,具有挡位多、结构简单、实现整车高动力性和高燃油经济性的优点。
