The invention discloses a hybrid power transmission which comprises an engine, a clutch, a first motor, a second motor, a gear set, a synchronizer, an input shaft and an output shaft. The clutch is used for combining or cutting off power transmission between the engine and the input shaft; a motor shaft of the first motor is connected with the input shaft or a flywheel output end of the engine through gear transmission; the shift gear set comprises at least two groups of driving gears and driven gears which are meshed with each other, the driving gears are hollowly sleeved on the input shaft, and the driven gears are sleeved on the output shaft; a motor shaft of the second motor is fixedly connected with one of the driving-gear gears through a shaft sleeve which is hollowly sleeved on the input shaft; the synchronizer is used for selectively combining or cutting off power transmission in the direction from the input shaft and the gear gear set to the output shaft. According to the hybrid power transmission, high-efficiency output of the transmission under the conditions of low, medium and high vehicle speeds and various loads is achieved, the structure is simple, and space arrangement is compact.

    本发明公开一种混合动力变速器,包括发动机、离合器、第一电机、第二电机、档位齿轮组、同步器、输入轴和输出轴;离合器用于结合或者切断发动机与输入轴之间的动力传输;第一电机的电机轴通过齿轮传动与输入轴或者发动机的飞轮输出端相连;档位齿轮组包括至少两组相互啮合的主动齿轮和从动齿轮,主动齿轮空套在输入轴上,从动齿轮套接在输出轴上;第二电机的电机轴通过一空套在输入轴上的轴套与主动档位齿轮中的一个进行固接;同步器用于选择性结合或者切断输入轴、档位齿轮组至输出轴方向上的动力传输。本发明技术方案实现变速器在低中高车速和各种负载情况下的高效率输出且结构简单,空间布置紧凑。
