The invention discloses a vehicle hybrid power driving system which comprises an engine, two motors, a planet row mechanism, a reduction gear and a differential mechanism. The planet row mechanism comprises a first planet row and a second planet row, and an inner gear ring and a planet carrier of each planet row are connected with each other to form a four-axis planetary gear train. The engine is connected with a sun gear of the first planet row, the generator is connected with an inner gear ring of the first planet row, and a sun gear of the second planet row serves as a power output shaft and is connected with the driving motor. When the engine works, the power system achieves a power split driving mode, the stepless speed change function of the whole vehicle is achieved through control of the double motors, and the engine is not affected by running working conditions to the maximum extent and works in a low-oil-consumption interval. The scheme can be used for front-drive and rear-drive vehicles, and can be used for deep hybrid power and plug-in hybrid power vehicles. The energy conversion efficiency is improved, and the reliability of motor operation is enhanced.
本发明公开了一种车辆混合动力驱动系统,包括发动机、两个电机、行星排机构、减速齿轮、差速器。行星排机构包括第一行星排和第二行星排,每个行星排的内齿圈和行星架彼此连接,构成一个四轴行星轮系。发动机与第一行星排的太阳轮连接,发电机与第一行星排的内齿圈连接,第二行星排的太阳轮作为动力输出轴同时与驱动电机连接。发动机工作时动力系统实现功率分流驱动模式,通过双电机的控制实现整车无级变速功能,使发动机最大程度不受行驶工况影响,工作在低油耗区间。该方案能够用于前驱和后驱车辆,满足深度混合动力和插电式混合动力汽车使用。提高了能源转换效率,增强了电机运行的可靠性。
