The invention discloses a series-parallel hybrid power system which comprises an engine, a motor and a differential mechanism. A power output shaft of the engine is connected with the differential mechanism through a clutch; a motor shaft of the motor is hollowly sleeved on a power output shaft of the engine and is connected with the differential mechanism, a differential mechanism lock is arranged in the differential mechanism, and the differential mechanism lock is used for controlling power transmission between the differential mechanism and the engine as well as between the differential mechanism and the motor; a transmission shaft is arranged at the axis of the side, away from the motor, of the differential mechanism shell, is connected with a transmission and outputs power to a vehicle drive axle. The series-parallel hybrid power system disclosed by the invention can better adapt to the urban operation road environment, the energy conservation and emission reduction performance of the hybrid power system can be brought into play to a greater extent, and the basic dynamic property of the whole vehicle can be ensured. Meanwhile, a plurality of working conditions are set for the engine, so that optimization design of the engine is facilitated, and good practical value is achieved.

    本发明公开了一种混联式混动系统,包括发动机、电动机以及差速器;所述发动机的动力输出轴通过离合器与所述差速器连接;所述电动机的电机轴空套在所述发动机的动力输出轴上,并与所述差速器连接,所述差速器内设有差速器锁,所述差速器锁用于控制所述差速器与所述发动机和所述电动机之间的动力传递;所述差速器壳体远离所述电动机的一侧轴心处设有传动轴,所述传动轴与变速器连接,并将动力输出至车辆驱动桥。本发明所公开的混联式混动系统能够更好适应城市运营道路环境,更大程度发挥混动系统的节能减排性能,又可以保证基本的整车动力性。同时发动机设定多个工作工况,便于发动机优化设计,具有较好的实用价值。
