The invention relates to a hybrid power transmission, a hybrid power transmission system and a vehicle, the hybrid power transmission comprises an input shaft, an output shaft, a first disconnecting device and a second disconnecting device, the input shaft comprises a core shaft connected to an engine and a sleeve shaft arranged on the outer side of the core shaft in a sleeving mode at intervals, and the core shaft and the sleeve shaft are connected in an on-off mode through the first disconnecting device; the output shaft is used for being connected with an axle; the first gear set is arranged between the sleeve shaft and the output shaft; and the first motor is selectively connected with the core shaft or the sleeve shaft. When the first motor is connected with the sleeve shaft, the connection with the engine can be disconnected, and pure electric driving is realized; when the first motor is connected with the mandrel, the first motor is connected with the engine, engine driving can be assisted, the rotating speed of the engine can be adjusted, the target rotating speed of the engine can be rapidly achieved, gear shifting is rapid, meanwhile, the engine can charge the first motor, the first motor can adjust the output torque of the engine, and torque shunting is achieved. When the engine charges the first motor, the first disconnecting device is disconnected, and the influence of loads on the sleeve shaft is reduced.

    本公开涉及一种混合动力变速器、混合动力变速系统和车辆,该混合动力变速器包括:输入轴,包括连接到发动机的芯轴和间隔套设在芯轴外侧的套轴,芯轴和套轴通过第一断开装置可通断地连接;输出轴,用于与车桥连接;第一齿轮组,设置在套轴和输出轴之间;第一电机,可选择性地与芯轴或套轴相连接。当第一电机与套轴相连接时,可断开与发动机的连接,实现纯电驱动;当第一电机与芯轴相连接时,第一电机与发动机连接,能够助力发动机驱动,还可以调节发动机的转速,使其快速达到目标转速,快速换挡,同时发动机可对第一电机充电,第一电机可调节发动机的输出扭矩,实现扭矩分流。在发动机对第一电机充电时,断开第一断开装置,减少套轴上负载的影响。
