The invention relates to a derivative configuration for assembling a double-motor hybrid power system for a gasoline direct injection engine, which comprises a finished automobile controller, a GDI engine, a motor, a high-voltage power battery and a speed changer, and is characterized in that the GDI engine is connected with an input shaft of the speed changer through a clutch, a I shaft motor isintegrated between the clutch and the speed changer; a rotor of the I shaft motor is connected with the input shaft of the speed changer by key joint; a II shaft motor is directly connected with a bevel gear of a main reducing gear through gear transmission; and the power output by the engine, the I shaft motor and the II shaft motor is transmitted to a driving wheel through the main reducing gear and a half shaft. The derivative configuration greatly improves the economic performance and emission performance of fuel of a finished automobile; simultaneously, because a GDI engine system has self-start function, the derivative configuration saves an engine starter and a generator of the prior automobile, and reduces the weight and cost of the finished automobile and the difficulty of overall arrangement.
Description
Technical field: [0001] The invention relates to a derivative configuration of a dual-motor hybrid power system equipped with a gasoline direct injection engine, which belongs to the automobile power transmission system technology. Background technique: [0002] Energy saving and environmental protection are the two major themes in the development of today's automobile industry. The innovations of automobile technology around these two themes emerge in an endless stream, among which the hybrid technology is a typical representative. At present, hybrid power technology has become a hot field of automobile technology research at home and abroad. Since Japan's Toyota Corporation and Honda Corporation successfully launched hybrid electric cars and achieved great success in the market, major international automobile companies have devoted themselves to the development of hybrid electric products. my country also invested heavily in the research and development of hybrid electric...
