The invention provides a dual-motor series-parallel hybrid power system, an engine and two motors are jointly connected into a coaxial dual-input gearbox, so that the whole system is small in occupiedspace, and energy can be recycled in time. The coaxial double-input gearbox comprises a shell, a first input shaft, a second hollow input shaft, an output shaft and an intermediate shaft, the first input shaft is coaxially arranged in a center cavity of the second hollow input shaft, an avoiding center cavity is formed in the position, corresponding to the first input shaft, of a TM motor, and the hollow transmission end of the TM motor is connected with the input end of the second hollow input shaft; the first input shaft penetrates through the avoiding center cavity and then is sequentiallyconnected with the output end of an Isg motor and one end of a clutch device, the output end of the engine is connected with the other end of the clutch device, the engine is connected with the firstinput shaft when the clutch device is in a closed state, and the output shaft is coaxially arranged behind the first input shaft with spacing. The rear end of the first input shaft protrudes backwards out of the second hollow input shaft and is provided with a power selection device.
本发明提供了一种双电机混联混合动力系统,通过发动机和两个电机共同接入同轴双输入变速箱,使得整个系统占用空间小,且能量可以及时回收。同轴双输入变速箱包括壳体、第一输入轴、第二空心输入轴、输出轴、中间轴,第一输入轴同轴布置于第二空心输入轴的中心腔内,TM电机的对应于第一输入轴的位置设置有避让中心腔,TM电机的空心传动端连接第二空心输入轴的输入端,第一输入轴贯穿避让中心腔后顺次连接Isg电机的输出端、离合装置的一端,发动机的输出端连接离合装置的另一端,离合装置闭合状态发动机连接第一输入轴,输出轴布置于第一输入轴的后方、同轴布置、且留有间隔,第一输入轴的后端后凸于第二空心输入轴并安装有动力选择装置。
