Kind of Hybrid hybrid drive system

The invention provides a series-parallel connection hybrid power driving system, belonging to the technology field of hybrid power automobiles. The series-parallel connection hybrid power driving system solves problem that the axial length of a current series-parallel connection hybrid power driving system is too long to be easily arranged. The series-parallel connection hybrid power driving system comprises a gearbox, an engine (E), and a first motor (M1) and a second motor (M2) capable of performing conversion of electric energy and mechanical energy, a driving shaft (S5) of the automobile is inserted in the box body of the gearbox, a motor shaft I (S1) of the first motor (M1), a motor shaft II S4 of the second motor (M2), and an output shaft (S2) of the engine (E) are all disposed in the box body of the gearbox, and at least two shafts of the motor shaft I (S1), the motor shaft II (S4), and the output shaft (S2) of the engine (E) are in an axial parallel arrangement. The invention provides a novel series-parallel connection hybrid power assembly configuration, the two motors are in an parallel arrangement, and the whole structure is compact, facilitating whole arrangement of the whole automobile.
