Abstract

The invention relates to a 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 is integratedbetween 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 integrated at the rear end of an outputshaft of the speed changer and connected with the output shaft of the speed changer by key joint; the front end of the output shaft of the speed changer is connected with a bevel gear of a main reducing gear through a gear; and the power output by the GDI engine, the I shaft motor and the II shaft motor is transmitted to a driving wheel through a differential mechanism and a half shaft. The 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 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 configuration of a dual-motor hybrid power system equipped with a gasoline direct injection engine, which belongs to the technology of an automobile power transmission system. 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 vehi...
