Hybrid power frame structure based on double-belt continuously variable transmission and hybrid power method

The invention discloses a hybrid power frame structure based on a double-belt continuously variable transmission and a hybrid power method. The hybrid power frame structure comprises an engine, five clutches, a P0 motor, two PS motors, a double-belt continuously variable transmission mechanism and a planetary gear mechanism. In the hybrid power driving system, a P0 motor is arranged at the front end of an engine and is flexibly connected with a crankshaft of the engine through a belt, clutches are arranged behind the engine, two clutches and a PS motor are arranged on each of a first output shaft and a second output shaft, and the PS motor is arranged between the two clutches. And finally the power of the first output shaft and the power of the second output shaft are gathered to the planetary gear mechanism. Pure electric drive (a PS motor is integrated in a speed change mechanism), single-belt engine direct drive, double-belt engine direct drive, single-belt hybrid power, double-belt hybrid power, single-mo
