Abstract

The invention relates to the field of vehicle hybrid power, and discloses a dual-motor hybrid powertrain. The dual-motor hybrid powertrain comprises an engine, a dual-motor power module and a dual-input-shaft transmission. The dual-motor power module comprises a first motor, a second motor, a first planetary line and a second planetary line, and the dual-input-shaft transmission includes a first input shaft, a second input shaft and a transmission device. The first planetary line and the second planetary line each include three rotating elements. The first motor, the engine and the first inputshaft are correspondingly connected with the three rotating elements of the first planetary line, and the second motor, the engine and the second input shaft are correspondingly connected with the three rotating elements of the second planetary line. The first input shaft and the second input shaft transmit power to automobile wheels separately through the transmission device, and the two planetary line are internally provided with lockup clutches. The dual-motor hybrid powertrain solves the problems of complicated structure, high electric energy consumption, poor gear shifting quality, difficult control and poor hybrid effect of a hybrid power system in the prior art.

Description

technical field [0001] The invention relates to the field of vehicle hybrid power, and discloses a dual-motor hybrid power assembly. Background technique [0002] At present, the hybrid power of automobiles is mostly in two forms. One is to connect a motor in series between the engine and the dual clutch, or between the dual clutch and the transmission; the other is to connect a motor drive mechanism in parallel to a certain gear gear; What kind of hybrid power based on dual-clutch automatic transmission has its disadvantages. First, it needs the clutch and shift synchronizer to cooperate with shifting. The matching control of the system is difficult and the shifting quality is poor; Working in the fuel-saving area, the fuel consumption is high. [0003] Therefore, it is urgent to develop a better hybrid mechanism. Contents of the invention [0004] The technical problem to be solved by the present invention is that the hybrid power system in the prior art has complex st...
