The invention provides a hybrid power system which is characterized in that an engine is connected with a first mechanical oil pump, so that the first mechanical oil pump operates when the engine operates; the differential mechanism is connected with a second mechanical oil pump, so that the second mechanical oil pump operates when wheels driven by the differential mechanism operate. A first one-way valve is arranged on the side, away from the differential mechanism, of the second mechanical oil pump, the two sides of the second one-way valve are connected with the two sides of the second mechanical oil pump correspondingly, and oil of the first one-way valve and the second one-way valve flows from the side close to the differential mechanism to the side away from the differential mechanism; therefore, when the differential rotates forwards, oil in the second mechanical oil pump flows to the to-be-cooled motor through the first one-way valve, and when the differential rotates backwards, oil in the second mechanical oil pump flows to the to-be-cooled motor through the second one-way valve. And whether the generator and the driving motor are cooled or not is controlled by simply electrifying or not the electromagnetic valve, so that the control is simple, and the cost is low.

    本发明提供了一种混合动力系统,发动机连接设置第一机械油泵,使得发动机运转则第一机械油泵运转;差速器连接设置第二机械油泵,使得与差速器所驱动的车轮运转则第二机械油泵运转。第二机械油泵远离差速器的一侧设有第一单向阀,第二单向阀的两侧分别连接第二机械油泵的两侧,第一单向阀、第二单向阀的油液流向为:从靠近差速器的一侧流向远离差速器一侧;从而使得:差速器正转时,第二机械油泵内的油液通过第一单向阀流向待冷却电机,差速器反转时,第二机械油泵内的油液通过第二单向阀流向待冷却电机,本发明无需复杂控制结构和控制方法,而是通过简单的电磁阀的通电与否来控制是否对发电机和驱动电机进行冷却,控制简单,且成本低。
