The invention relates to the technical field of hybrid electric vehicles, in particular to a dual-motor hybrid power transmission system. Comprising an engine, a generator, a driving motor, double clutches, a planet row, a synchronizer and a differential mechanism. A first shaft connected with an engine is connected with the double clutch; the double clutches comprise a first clutch and a second clutch; the first clutch is connected with a second shaft connected with the generator in a closed state; the generator is a motor capable of generating electricity and outputting power; the second clutch is connected with a planet carrier of the planet row in a closed state; the synchronizer comprises a gear hub and gear combination teeth; the differential mechanism is connected with an inner gear ring of the planet row through a gear transmission structure and is in transmission connection with the driving motor through a gear pair. The hybrid power transmission system is simple in structure and exquisite and compact in design, has multiple engine working modes, optimizes the engine direct-drive efficiency, reduces the high-speed direct-drive oil consumption, and is extremely rich in whole hybrid power working modes.
