Problems solved by technology

Chongqing University combines planetary gears with dual clutches, and has multiple gears and multiple transmission modes. When power transmission is performed in a certain mode, the motor must always be in working condition, and during the transmission process, the shaft of the DCT is always on. Rotation will reduce certain efficiency

Abstract

The mixed power drive unit based on double clutch automatic speed variator has one planet gear train, one double clutch automatic speed variator, three synchronizers and one brake. The planet gear train includes a planet gear, an outer gear and a sun gear; the double clutch automatic speed variator includes four shafts, two DCT clutches, four gear meshing pairs and two synchronizers. The present invention has the advantages of power synthesis between the engine and the motor with single planet gear rank, the combination with DCT, relatively broad transmission ratio range of stepless speed change and capacity of expanding the use range of engine.

Description

technical field [0001] The invention relates to a power drive device, in particular to a hybrid drive device based on a dual-clutch automatic transmission. Background technique [0002] As an important transition product for pure electric vehicles to replace internal combustion engine vehicles, hybrid vehicles not only have obvious advantages in fuel saving and environmental protection, but also have power and mileage comparable to current internal combustion engine vehicles, so they have become the research and development of major automobile companies today. hotspots. Hybrid powertrain is one of the key technologies of HEVs. A good transmission system can not only maximize the efficiency of the engine, but also ensure the cooperation with the motor, and carry out reasonable power distribution according to the control strategy, thereby improving the operating efficiency of the vehicle. At present, the German LUK Company, General Motors Technology Corporation of the United...
