Hybrid transmission device of motor vehicle

A hybrid power transmission device of a motor vehicle comprises an engine, a generator and a driving motor, an input shaft is fixedly connected with the engine, the driving motor is fixedly connected with a hollow shaft, the generator is fixedly connected with a solid shaft, the hollow shaft is sleeved on the solid shaft to form a concentric shaft, and an output shaft is parallel to the solid shaft. The input shaft and the output shaft are located on the same axis. A first driving gear is fixed to the input shaft in the circumferential direction, a first driven gear is fixed to the solid shaft in the circumferential direction, and the first driven gear is meshed with the first driving gear. A second driving gear is circumferentially fixed on the hollow shaft, a second driven gear is circumferentially fixed on the output shaft, and the second driven gear is meshed with the second driving gear; a first clutch is arranged between the hollow shaft and the first driven gear, a first friction disc of the first clut
