The invention relates to an automobile hybrid power transmission device and an automobile. The automobile hybrid power transmission device comprises an engine, a first motor, a second motor, a PCU and a transmission. The engine and the first motor are connected with the transmission through the PCU, and the transmission is connected with a power output shaft. The transmission is further connected with the second motor and used for adjusting the speed of the second motor. According to the technical scheme, the transmission is arranged and connected with the second motor, the transmission is further connected with the power output shaft, and the speed of the second motor is output after being adjusted. The high-speed problem of the second motor is solved through speed regulation of the transmission, so that the problems of high dynamic balance difficulty of the motor and bearing rotating speed limitation are solved. And meanwhile, the influence of NVH of the power assembly on the comfort of the whole vehicle is also reduced. In addition, the transmission can improve the comprehensive efficiency of the operation condition of the second motor, meanwhile, the working rotating speed and the working load of a planetary speed reduction mechanism are reduced, and the service life of the second motor can be prolonged.
本发明涉及了一种汽车混合动力传动装置及汽车,包括发动机、第一电机、第二电机、PCU以及变速器;所述发动机与所述第一电机通过PCU与所述变速器连接,所述变速器与动力输出轴连接;所述变速器还与所述第二电机连接,所述变速器用于调整所述第二电机的速度。上述技术方案设置了变速器,变速器与第二电机连接,变速器还与动力输出轴连接,将第二电机的速度调整后输出。通过变速器调速解决了第二电机的高速化问题,从而避免了电机动平衡难度大和轴承转速限制的问题。同时也降低了动力总成的NVH对整车舒适性的影响。另外,变速器还会提高第二电机运行工况的综合效率,同时降低相比行星减速机构的工作转速和工作载荷,可提高第二电机的使用寿命。
